Health services research (HSR) is a field of study that examines how social factors, financing systems, organizational structures and processes, health technologies, and personal behaviors affect access to health care, the quality and cost of health care, and health and well-being. HSR approaches can help build the occupational therapy evidence base, particularly in relation to population health. Data from electronic health record (EHR) systems provide a rich resource for applying HSR approaches to examine the value of occupational therapy services. Transparency about data preparation procedures is important for interpreting results. Based on our findings, we describe a six-step cleaning protocol for preparing EHR and billing data from an inpatient rehabilitation facility for research and provide recommendations for the field based on our experience. Using and reporting similar strategies across studies will improve efficiency and transparency, and facilitate comparability of results.

Archives of Rehabilitation Research and Clinical Translation. Advance online publication. https://doi.org/10.1016/j.arrct.2024.100370 Show abstract
Objective. To examine associations among the time and content of rehabilitation treatment with self-care and mobility functional gain rate for adults with acquired brain injury.
Design. Retrospective cohort study using electronic health record and administrative billing data.
Setting. Inpatient rehabilitation unit at a large, academic medical center.
Participants. Adults with primary diagnosis of stroke, traumatic brain injury, or nontraumatic brain injury admitted to the inpatient rehabilitation unit between 2012 and 2017 (N=799).
Interventions. Not applicable.
Main Outcome Measures. Gain rate in self-care and mobility function, using the Functional Independence Measure. Hierarchical regression models were used to identify the contributions of baseline characteristics, units, and content of occupational therapy, physical therapy, and speech-language pathology treatment to functional gain rates.
Results. Median length of rehabilitation stay was 10 days (interquartile range, 8-13d). Patients received an mean of 10.62 units of therapy (SD, 2.05) daily. For self-care care gain rate, the best-fitting model accounted for 32% of the variance. Occupational therapy activities of daily living units were positively associated with gain rate. For mobility gain rate, the best-fitting model accounted for 37% of the variance. Higher amounts of physical therapy bed mobility training were inversely associated with mobility gain rate.
Conclusions. More activities of daily living in occupational therapy is associated with faster improvement on self-care function for adults with acquired brain injury, whereas more bed mobility in physical therapy was associated with slower improvement. A potential challenge with value-based payments is the alignment between clinically appropriate therapy activities and the metrics by which patient improvement are evaluated. There is a risk that therapists and facilities will prioritize activities that drive improvement on metrics and deemphasize other patient-centered goals.

The purpose of this study was to differentiate clinically meaningful improvement or deterioration from normal fluctuations in patients with disorders of consciousness (DoC) following severe brain injury. We computed indices of responsiveness for the Coma Recovery Scale-Revised (CRS-R) using data from a clinical trial of 180 participants with DoC. We used CRS-R scores from baseline (enrollment in a clinical trial) and a four-week follow-up assessment period for these calculations. To improve precision, we transformed ordinal CRS-R total scores (0 to 23 points) to equal-interval measures on a 0-to-100-unit scale using Rasch Measurement theory. Using the 0-to-100 unit total Rasch measures, we calculated distribution-based 0.5 standard deviation (SD) minimal clinically important difference, minimal detectable change using 95% confidence intervals, and conditional minimal detectable change using 95% confidence intervals. The distribution-based minimal clinically important difference evaluates group-level changes, whereas the minimal detectable change values evaluate individual-level changes. The minimal clinically important difference and minimal detectable change are derived using the overall variability across total measures at baseline and four weeks. The conditional minimal detectable change is generated for each possible pair of CRS-R Rasch person measures and accounts for variation in standard error across the scale. We applied these indices to determine the proportions of participants who made a change beyond measurement error within each of the two sub-groups, based on treatment arm (amantadine hydrochloride or placebo) or categorization of baseline Rasch person measure to states of consciousness (i.e., unresponsive wakefulness syndrome and minimally conscious state). We compared the proportion of participants in each treatment arm who made a change according to the minimal detectable change and determined whether they also changed to another state of consciousness. CRS-R indices of responsiveness (using the 0-100 transformed scale) were as follows: 0.5SD minimal clinically important difference = 9 units, minimal detectable change = 11 units, and the conditional minimal detectable change ranged from 11 to 42 units. For the amantadine and placebo groups, 67% and 58% of participants showed change beyond measurement error using the minimal detectable change, respectively. For the unresponsive wakefulness syndrome and minimally conscious state groups, 52% and 67% of participants changed beyond measurement error using the minimal detectable change, respectively. Among 115 participants (64% of the total sample) who made a change beyond measurement error, 29 participants (25%) did not change state of consciousness. CRS-R indices of responsiveness can support clinicians and researchers in discerning when behavioral changes in patients with DoC exceed measurement error. Notably, the minimal detectable change can support the detection of patients who make a ‘true’ change within or across states of consciousness. Our findings highlight that continued use of ordinal scores may result in incorrect inferences about the degree and relevance of a change score.

Neuro-occupation was developed to study the relationship between the nervous system and occupation. Pragmatic implications of neuro-occupation have not been previously summarized. This study aimed to determine how neuro-occupation has been defined, applied across relevant fields, and evolved over time. We performed a scoping review following the Arksey and O’Malley framework. Twenty-five works related to neuro-occupation published between 1997 and 2020 were included. We found that neuro-occupation evolved from utilization primarily in the United States to an international term applied to different clinical populations. Common themes were: (a) the reciprocal relationship between the nervous system and occupations; (b) the Intention, Meaning, and Perception (IMP) model of neuro-occupation; and (c) pragmatic implications for occupational therapy practice and interventions. We suggest an updated definition of neuro-occupation. In addition, we contend that although the term neuro-occupation was developed in response to historical debates in occupational therapy, continued use creates more confusion than clarity.

Transitioning from one electronic health record to another: A systematic review. Journal of General Internal Medicine, 38(Suppl 4), 956–964. https://doi.org/10.1007/s11606-023-08276-3 Show abstract
Background. Transitioning to a new electronic health record (EHR) presents different challenges than transitions from paper to electronic records. We synthesized the body of peer-reviewed literature on EHR-to-EHR transitions to evaluate the generalizability of published work and identify knowledge gaps where more evidence is needed.
Methods. We conducted a broad search in PubMed through July 2022 and collected all publications from two prior reviews. Peer-reviewed publications reporting on data from an EHR-to-EHR transition were included. We extracted data on study design, setting, sample size, EHR systems involved, dates of transition and data collection, outcomes reported, and key findings.
Results. The 40 included publications were grouped into thematic categories for narrative synthesis: clinical care outcomes (n = 15), provider perspectives (n = 11), data migration (n = 8), patient experience (n = 4), and other topics (n = 5). Many studies described single sites that are early adopters of technology with robust research resources, switching from a homegrown system to a commercial system, and emphasized the dynamic effect of transitioning on important clinical care and other outcomes over time.
Discussion. The published literature represents a heterogeneous mix of study designs and outcome measures, and while some of the stronger studies in this review used longitudinal approaches to compare outcomes across more sites, the current literature is primarily descriptive and is not designed to offer recommendations that can guide future EHR transitions. Transitioning from one EHR to another constitutes a major organizational change that requires nearly every person in the organization to change how they do their work. Future research should include human factors as well as diverse methodological approaches such as mixed methods and implementation science.

Using research to transform electronic health record modernization: Advancing a VA partnered research agenda to increase research impacts. Journal of General Internal Medicine, 38(Suppl 4), 965–973. https://doi.org/10.1007/s11606-023-08289-y Show abstract
Background. The U.S. Department of Veterans Affairs (VA) is undergoing an enterprise-wide transition from a homegrown electronic health record (EHR) system to a commercial off-the-shelf product. Because of the far-reaching effects of the EHR transformation through all aspects of the healthcare system, VA Health Services Research and Development identified a need to develop a research agenda that aligned with health system priorities so that work may inform evidence-based improvements in implementation processes and outcomes.
Objective. The purpose of this paper is to report on the development of a research agenda designed to optimize the EHR transition processes and implementation outcomes in a large, national integrated delivery system.
Design. We used a sequential mixed-methods approach (portfolio assessment, literature review) combined with multi-level stakeholder engagement approach that included research, informatics, and healthcare operations experts in EHR transitions in and outside the VA. Data from each stage were integrated iteratively to identify and prioritize key research areas within and across all stakeholder groups.
Participants. VA informatics researchers, regional VA health system leaders, national VA program office leaders, and external informatics experts with EHR transition experience.
Key Results. Through three rounds of stakeholder engagement, priority research topics were identified that focused on operations, user experience, patient safety, clinical outcomes, value realization, and informatics innovations.
Conclusions. The resulting EHR-focused research agenda was designed to guide development and conduct of rigorous research evidence aimed at providing actionable results to address the needs of operations partners, clinicians, clinical staff, patients, and other stakeholders. Continued investment in research and evaluation from both research and operations divisions of VA will be critical to executing the research agenda, ensuring its salience and value to the health system and its end users, and ultimately realizing the promise of this EHR transition.

Cogan, A. M., & Bailie, J. M. (2023). Therapeutic relationship in mTBI rehabilitation: The disparity between the illness experience and clinical definitions. Military Medicine, 188(9-10), e3010–e3016. https://doi.org/10.1093/milmed/usad143 Show abstract
Introduction. A positive therapeutic relationship is characterized by trust and mutually perceived genuineness. It is positively associated with patients’ adherence to treatment, satisfaction, and health outcomes. When service members with a history of mild traumatic brain injury (mTBI) present to rehabilitation clinics with nonspecific symptoms, a disparity between their experience of disability and clinical expectations of mTBI may disrupt the establishment of a positive therapeutic relationship between patients and providers. The objectives of this study are to (1) explore disparities between military service members and rehabilitation clinicians about the clinical diagnosis and illness experience of mTBI and (2) identify barriers to the establishment of a positive therapeutic relationship.
Materials and Methods. This is a qualitative descriptive study of military service members with prior mTBI (n = 18) and clinicians (n = 16) who participated in interviews and focus groups. Data were analyzed thematically using Kleinman’s framing of illness experience and clinical diagnosis.
Results. Three themes reflected the potential breakdowns in the therapeutic relationship. The first theme, clinical expectations for post-injury recovery versus patients’ experience of ongoing disability, reflects the inconsistency between clinicians’ expectations of symptom resolution within 90 days following mTBI and service members’ experiences of symptoms that worsened over several months or years. The second theme, symptom attribution to mental health conditions versus tissue injury, describes the difficulty in attributing symptoms to the physical impact of the mTBI or mental health diagnoses that may also stem from the injury event. The third theme, suspected malingering versus valid disability, describes clinicians’ reports of frustration with cases in which they suspected malingering for secondary gains in contrast with service members’ feelings that their problems were not taken seriously by clinicians.
Conclusions. This study extended previous research on therapeutic relationships by examining the situation of mTBI rehabilitation services for military service members. The findings reinforce the best practice recommendations of acknowledging patients’ experiences, addressing the presenting symptoms and problems, and encouraging progressive return to activity following mTBI. Acknowledgment of and attention to patients’ illness experience by rehabilitation clinicians is necessary and important for supporting a positive therapeutic relationship and ultimately to optimize patients’ health outcomes and reduce disability.

Journal of General Internal Medicine. Advance online publication. https://doi.org/10.1007/s11606-023-08338-6 Show abstract
Background. The Department of Veterans Affairs (VA) has embarked on the largest system-wide electronic health record (EHR) transition in history. To date, most research on EHR-to-EHR transitions has focused on employee and system transition-related needs, with limited focus on how patients experience transitions.
Objective. (1) Understand patients’ preferences for information and support prior to an EHR transition, and (2) examine actual patient experiences that occurred at facilities that implemented a new EHR.
Design. We used a two-step approach. We had discussions with geographically diverse patient advisory groups. Discussions informed semi-structured, qualitative interviews with patients.
Participants. Patients affected by the EHR transition.
Main Measures. We met with four patient advisory groups at sites that had not transitioned their EHR. Interviews were conducted with patients who received care at one of two facilities that recently transitioned to the new EHR.
Key Results. Patient advisors identified key areas important to patients during an EHR transition. 1) Use a range of communication strategies to reach diverse populations, especially older, rural patients. 2) Information about the EHR transition should be clear and reinforce trustworthiness. 3) Patients will need guidance using the new patient portal. From the patient interviews, we learned if and how these key areas mapped onto patients’ experiences. Patients at the sites that had transitioned learned about the new EHR through a variety of modalities, including letters and banners on the patient portal. However, their experiences varied in terms of information quality, leading to frustrations during and between healthcare encounters. Patient portal issues exacerbated frustrations. These raised concerns about the accuracy and security of the overall EHR.
Conclusions. Maintaining clear communication across patients, local leadership, and providers throughout an EHR transition is essential for successful implementation. Patient-facing communications can set expectations, and help patients receive adequate support, particularly related to the patient portal.

Archives of Physical Medicine and Rehabilitation, 104(8), 1343-1355. https://doi.org/10.1016/j.apmr.2023.03.036 Show abstract
Objective. To develop new diagnostic criteria for mild traumatic brain injury (TBI) that are appropriate for use across the lifespan and in sports, civilian trauma, and military settings.
Design. Rapid evidence reviews on 12 clinical questions and Delphi method for expert consensus.
Participants. The Mild Traumatic Brain Injury Task Force of the American Congress of Rehabilitation Medicine Brain Injury Special Interest Group convened a Working Group of 17 members and an external interdisciplinary expert panel of 32 clinician-scientists. Public stakeholder feedback was analyzed from 68 individuals and 23 organizations.
Results. The first two Delphi votes asked the expert panel to rate their agreement with both the diagnostic criteria for mild TBI and the supporting evidence statements. In the first round, 10 of 12 evidence statements reached consensus agreement. Revised evidence statements underwent a second round of expert panel voting, where consensus was achieved for all. For the diagnostic criteria, the final agreement rate, after the third vote, was 90.7%. Public stakeholder feedback was incorporated into the diagnostic criteria revision prior to the third expert panel vote. A terminology question was added to the third round of Delphi voting, where 30 of 32 (93.8%) expert panel members agreed that ‘the diagnostic label ‘concussion’ may be used interchangeably with ‘mild TBI’ when neuroimaging is normal or not clinically indicated.’
Conclusions. New diagnostic criteria for mild TBI were developed through an evidence review and expert consensus process. Having unified diagnostic criteria for mild TBI can improve the quality and consistency of mild TBI research and clinical care.

People who experience disorders of consciousness (DoC) following a severe traumatic brain injury (TBI) have complex rehabilitation needs addressed by occupational therapy. To examine the effectiveness of interventions to improve arousal and awareness of people with DoC following a TBI. For this systematic review, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched six databases in collaboration with a research librarian. Twenty-seven studies were included and grouped thematically. Multimodal sensory stimulation, familiar voices telling structured stories, and transcranial direct current stimulation had a moderate level of evidence. Multimodal sensory stimulation had the strongest evidence in support of its use in clinical practice. Occupational therapy practitioners should administer multimodal stimuli frequently as studies reported administering these interventions at least twice daily. Occupational therapy practitioners should incorporate personally relevant, meaningful, salient stimuli into interventions when treating patients with DoC.

Health Services Research, 58(S1), 9-15. https://doi.org/10.1111/1475-6773.14054 Show abstract
Objective. To examine by age, the veterans' report on whether components of age-friendly health systems were discussed during primary care visits.
Data Sources and Study Setting. Veterans Affairs (VA) Survey of Healthcare Experience of Patients from October 2015 to September 2019.
Study Design. Cross-sectional survey of VA users by age group (18–44 years, 45–64 years, 65+ years; N = 1,042,318). We used weighted logistic regression models to evaluate disparities in whether veterans discussed with anyone in their provider's office: health goals, depression symptoms, stress, personal problems, and medications. Models were adjusted for socio-demographic characteristics (sex, socioeconomic status, education, rurality) and comorbidity.
Data Collection/Extraction Method. Surveys were administered by mail and online. Additional veteran characteristics were extracted from VA administrative data.
Principal Findings. In unadjusted analyses, VA users age 18–44 had a higher (−8.2%; CI: −9.0, −7.3) and users aged 45 to 64 had lower (4.0%; CI: 3.7, 4.3) predicted, probably discussing health goals compared to age 65+. Fewer VA users age 65+ reported discussing depression symptoms, personal problems, and stress than other age groups, whereas more VA users age 65+ discussed medications. Results were unchanged after adjusting for socio-demographics and comorbidity.
Conclusions. Delivery of goal-concordant care relies on understanding the needs of individual patients. Lower rates of discussing what matters and mood represent potential missed opportunities to deliver age-friendly care for older veterans.

Objectives. This study explored the association between cognitive impairment at admission with self-care and mobility gain rate (amount of change per week) during a post-acute care stay (admission to discharge) for older adults with stroke.
Design. Retrospective cohort study.
Setting and Participants. Four inpatient rehabilitation and 6 skilled nursing facilities. A total of 100 adults with primary diagnosis of stroke; mean age 79 years (SD 7.7); 67% women.
Methods. Retrospective cohort study. We evaluated the extent to which cognitive impairment at admission explained variation in weekly gain rate separately for self-care and mobility. Additional covariates were occupational and physical therapy minutes per day, self-care and mobility function at admission, age, and number of comorbidities.
Results. Participants were classified as having severe (n = 16), moderate (n = 39), or mild (n = 45) cognitive impairment at admission. Occupational therapy minutes per day (β = 0.04; P < .01) and Functional Independence Measure (FIM) self-care function at admission (β = 0.48; P < .01) were both significantly associated with self-care gain rate (Adjusted R2 = 0.18); cognitive impairment group, age, and number of comorbidities were not significant. Only FIM mobility function at admission (β = 0.29; P < .001) was significantly associated with mobility gain rate (Adjusted R2 = 0.18); cognitive impairment group, physical therapy minutes, age, and number of comorbidities were not significant.
Conclusions and Implications. These results provide preliminary evidence that patients with stroke who have severe cognitive impairment may benefit from intensive therapy services as well as less severely impaired patients, particularly occupational therapy for improvement in self-care function.

Determining the hierarchy of Coma Recovery Scale-Revised rating scale categories and alignment with Aspen consensus criteria for patients with brain injury: A Rasch Analysis. Journal of Neurotrauma, 39(19-20), 1417-1428. https://doi.org/10.1089/neu.2022.0095 Show abstract
This study aimed to empirically evaluate the hierarchical structure of the Coma Recovery Scale-Revised (CRS-R) rating scale categories and their alignment with the Aspen consensus criteria for determining disorders of consciousness (DoC) following a severe brain injury. CRS-R data from 262 patients with DoC following a severe brain injury were analyzed applying the partial credit Rasch Measurement Model. Rasch Analysis produced logit calibrations for each rating scale category. Twenty-eight of the 29 CRS-R rating scale categories were operationalized to the Aspen consensus criteria. We expected the hierarchical order of the calibrations to reflect Aspen consensus criteria. We also examined the association between the CRS-R Rasch person measures (indicative of performance ability) and states of consciousness as determined by the Aspen consensus criteria. Overall, the order of the 29 rating scale category calibrations reflected current literature regarding the continuum of neurobehavioral function: category 6 “Functional Object Use” of the Motor item was hardest for patients to achieve; category 0 “None” of the Oromotor/Verbal item was easiest to achieve. Of the 29 rating scale categories, six were not ordered as expected. Four rating scale categories reflecting the Vegetative State (VS)/Unresponsive Wakefulness Syndrome (UWS) had higher calibrations (reflecting greater neurobehavioral function) than the easiest Minimally Conscious State (MCS) item (category 2 “Fixation” of the Visual item). Two rating scale categories, one reflecting MCS and one not operationalized to the Aspen consensus criteria, had higher calibrations than the easiest eMCS item (category 2 “Functional: Accurate” of the Communication item). CRS-R person measures (indicating amount of neurobehavioral function) and states of consciousness, based on Aspen consensus criteria, showed a strong correlation (rs = 0.86; p < 0.01). Our study provides empirical evidence for revising the diagnostic criteria for MCS to also include category 2 “Localization to Sound” of the Auditory item and for Emerged from Minimally Conscious State (eMCS) to include category 4 “Consistent Movement to Command” of the Auditory item.

Introduction. Historically, heterogeneous outcome assessments have been used to measure recovery of consciousness in patients with disorders of consciousness (DoC) following traumatic brain injury (TBI), making it difficult to compare across studies. To date, however, there is no comprehensive review of clinical outcome assessments that are used in intervention studies of adults with DoC. The objective of this scoping review is to develop a comprehensive inventory of clinical outcome assessments for recovery of consciousness that have been used in clinical studies of adults with DoC following TBI.
Methods and analysis. The methodological framework for this review is: (1) identify the research questions, (2) identify relevant studies, (3) select studies, (4) chart the data, (5) collate, summarise and report results and (6) consult stakeholders to drive knowledge translation. We will identify relevant studies by searching the following electronic bibliographic databases: PubMed, Scopus, EMBASE, PsycINFO and The Cochrane Library (including Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials and Cochrane Methodology Register). Criteria for article inclusion are published in the English-language, peer-reviewed studies of interventions aimed at facilitating recovery of consciousness among adults (> 18 years) with DoC following a severe TBI, published from January 1986 to December 2020. Articles meeting inclusion criteria at this stage will undergo a full text review. We will chart the data by applying the WHO International Classification of Functioning, Disability and Health Framework to identify the content areas of clinical outcome assessments. To support knowledge translation efforts, we will involve clinicians and researchers experienced in TBI care throughout the project from conceptualisation of the study through dissemination of results.

Participation mediates the relationship between postconcussive symptoms and suicidal ideation among veterans. American Journal of Occupational Therapy, 76(3), 7603205020. https://doi.org/10.5014/ajot.2022.048561 Show abstract
Importance. Veterans with mild traumatic brain injury (mTBI) and associated symptoms are at risk for suicide. Postconcussive symptoms (PCS) may heighten risk for suicidal thoughts by limiting veterans’ participation.
Objective. To investigate whether participation mediates the relationship between PCS and suicidal ideation.
Design. Cross-sectional, exploratory design. Structural equation models were used to investigate whether participation mediated the relationship between PCS and suicidal ideation.
Setting. Community.
Participants. Veterans with mTBI (N = 145).
Outcomes and Measures. The Ohio State University TBI Identification Method was used to establish mTBI diagnosis. We identified latent variables for PCS and participation using the Neurobehavioral Symptom Inventory and select domains of the Medical Outcomes Study Short Form–36, respectively. We used the Beck Scale for Suicide Ideation to measure the presence of suicidal ideation.
Results. Participation mediated the relationship between PCS and the presence of suicidal ideation (odds ratio [OR] = 1.09, p = .011). More severe PCS were associated with lesser participation (β = –.86, p < .001); greater participation was associated with lower odds of suicidal ideation (OR = 0.92, p = .007).
Conclusions and Relevance. PCS may heighten risk for suicidal thoughts among veterans by limiting successful participation, a primary target of occupational therapy intervention. Thus, the results suggest that occupational therapy practitioners can play a substantial role in suicide prevention services for veterans with mTBI. Preventive services could mitigate suicide risk among veterans with mTBI by enabling sustained engagement in meaningful and health-promoting activity (e.g., reasons for living) and targeting PCS.

Archives of Physical Medicine and Rehabilitation, 103(1), 90-97. https://doi.org/10.1016/j.apmr.2021.08.017 Show abstract
Objective. To quantify the economic burden of all-cause health care resource utilization (HCRU) among adults with and without chronic vestibular impairment (CVI) after a mild traumatic brain injury (mTBI).
Design. Retrospective matched cohort study.
Setting. IQVIA Integrated Data Warehouse.
Participants. People with mTBI+CVI (n=20,441) matched on baseline age, sex, year of mTBI event, and Charlson Comorbidity Index (CCI) score to people with mTBI only (n=20,441) (N=40,882).
Interventions. Not applicable.
Main Outcome Measures. All-cause health HCRU and costs at 12 and 24 months post mTBI diagnosis.
Results. People with mTBI+CVI had significantly higher all-cause HCRU and costs at both time points than those with mTBI only. Multivariable regression analysis showed that, when controlling for baseline variables, costs of care were 1.5 times higher for mTBI+CVI than mTBI only.
Conclusions. People who developed CVI after mTBI had greater overall HCRU and costs for up to 2 years after the injury event compared with people who did not develop CVI after controlling for age, sex, region, and CCI score. Further research on access to follow-up services and effectiveness of interventions to address CVI is warranted.

Psychometric properties and sex differences on the Mayo-Portland Adaptability Inventory Participation subscale (M2PI) in veterans with traumatic brain injury. Archives of Physical Medicine and Rehabilitation, 102(11), 2193-2200. https://doi.org/10.1016/j.apmr.2021.06.003 Show abstract
Objective. To evaluate the structural validity of the Mayo-Portland Adaptability Inventory Participation Index (M2PI) in a sample of veterans and to assess whether the tool functioned similarly for male and female veterans.
Design. Rasch analysis of M2PI records from the National Veterans Traumatic Brain Injury Health Registry database from 2012-2018.
Setting. National VA Polytrauma System of Care outpatient settings.
Participants. Veterans with a clinically confirmed history of traumatic brain injury (TBI) (N=6065; 94% male).
Interventions. Not applicable.
Main Outcome Measures. M2PI, a 5-point Likert-type scale with 8 items. For this analysis, the 2 employment items were treated individually for a total of 9 items.
Results. The employment items misfit the Rasch Measurement model (paid employment mean square [MnSq]=1.40; other employment MnSq=1.34) and were removed from subsequent iterations. The final model had eigenvalue 1.87 on the first contrast, suggesting unidimensionality of the remaining 7 items. Item order from least to most participation restriction was transportation, self-care, residence management, financial management, initiation, leisure, and social contact. Wright's person separation reliability for nonnormal distributions was 0.93, indicating appropriateness of M2PI for making individual-level treatment decisions. Mean person measure was −0.92±1.34 logits, suggesting that participants did not report restrictions on most items (item mean=0 logits). A total of 3.8% of the sample had the minimum score (no impairment on all items), and 0.2% had the maximum score. Four items had different item calibrations (≥0.25 logits) for female compared with male veterans, but the hierarchy of items was unchanged when the female sample was examined separately.
Conclusions. These findings suggest that, although employment is a poor indicator of participation restrictions among veterans with TBI, the M2PI is unidimensional. Because of subtle differences in scale function between male and female participants, M2PI should be part of a more thorough clinical interview about participation strengths and restrictions.

In this paper, we explore how socially constructed hegemonic masculinity permeates military culture, and how this cultural context intersects with the seeking and receiving of health care by active-duty US military service members with chronic mild traumatic brain injury (mTBI) (n = 18). Data were collected through individual interviews and focus groups. Using Bourdieu’s theory of practice as an analytical framework, we identified four themes: maintenance of social capital, remaining in the field, reframing health care use to bolster social capital, and risk of health care use as not being rewarded. Each emerged from statements about why participants had avoided seeking health care for physical and psychological needs during their military service. We consider our findings in the context of maintaining status within an institutional steeped in hegemonic masculinity and describe implications for reframing caring for the body and dealing with problems as masculine acts.

Archives of Physical Medicine and Rehabilitation, 102(5), 881-887. https://doi.org/10.1016/j.apmr.2020.10.123 Show abstract
Objectives. To explore the association between therapy minutes per length of stay (LOS) day (TMLD), functional outcomes, and rate of functional recovery among older adults after elective hip or knee replacement surgery across postacute (PAC) settings.
Design. Secondary analysis of data collected for an observational cohort study from 2005 to 2010.
Setting. Four inpatient rehabilitation facilities (IRF) and 7 skilled nursing facilities (SNF).
Participants. Adults aged 65 years or older (N=162) with Medicare fee-for-service insurance and a primary diagnosis of elective hip or knee replacement.
Interventions. Not applicable.
Main Outcome Measures. FIM mobility and self-care measures at discharge.
Results. The TMLD was divided into high, medium, and low categories. Participants were grouped into low, medium, and high gain rate groups based on their average change in mobility and self-care FIM measures per LOS day. Gain rate and TMLD groups were crossmapped to create 9 gain-TMLD groups separately for mobility and self-care. There were no significant differences in admission mobility or self-care measures by gain rate and TMLD trajectory or by facility type (IRF or SNF). TMLD was not significantly associated with discharge mobility measures. Participants in high gain trajectories attained independence with mobility and self-care tasks at discharge regardless of TMLD. Those in low gain trajectories needed supervision or assistance on all mobility tasks. Older age and greater pain at discharge were significantly associated with lower odds of being in the medium or high gain rate groups.
Conclusions. For clinicians and facility managers who must care for patients with constrained resources, the shift to value-based reimbursement for rehabilitation services in PAC settings has reinvigorated the question of whether the duration of therapy provided influences patient outcomes. Three hours of daily therapy after joint replacement surgery may exceed what is necessary for recovery. Postsurgical pain management remains a significant challenge in older adults.

Objectives. Cognitive impairment is highly prevalent after stroke, with 77% of people having impairment in at least 2 cognitive domains. The purpose of this study is to describe the association between therapy minutes per length of stay (LOS) day and cognitive recovery in patients receiving rehabilitation services in inpatient post-acute care facilities following a stroke.
Design. Secondary analyses of data collected in inpatient rehabilitation and skilled nursing facilities from 2005 to 2010 for an observational cohort study.
Setting and Participants. Participants were adults aged ≥65 years with Medicare insurance and primary diagnosis of stroke (N = 100). Participants who met criteria for dementia (n = 5) were excluded from analyses. We calculated therapy minutes per LOS day for occupational therapy, physical therapy, speech-language pathology, and all therapies combined; therapy times were dichotomized into high or low minutes per LOS day (MLD). We used an ordinary least squares regression model for cognitive outcome at discharge to control for cognitive status at admission, therapy intensity by discipline, and LOS.
Results. At baseline, participants were classified as having severe (n = 11), moderate (n = 39), or mild (n = 45) cognitive impairment. Impairment groups were not significantly different on any demographic variables. The adjusted regression model showed that high occupational therapy MLD (>50 minutes per LOS day) (P = .028) was significantly associated with cognitive measure at discharge compared with low occupational therapy MLD when controlling for cognitive impairment group at baseline (P < .001). Neither high physical therapy MLD nor speech-language pathology MLD was significantly associated with cognitive outcome relative to their respective low TMLD groups.
Conclusions and Implications. Our results show that higher-intensity occupational therapy services were associated with better cognitive outcome at discharge from inpatient rehabilitation after stroke. Findings also suggest that volume of therapy alone does not necessarily produce optimal outcomes. Both amount and type of therapy should be tailored to meet the needs of individual patients.

Archives of Physical Medicine and Rehabilitation, 102(1), 106-114. https://doi.org/10.1016/j.apmr.2020.07.003 Show abstract
Objective. To combine items from the Functional Independence Measure, Minimum Data Set (MDS) 2.0, and the Outcome and Assessment Information Set (OASIS)-B to reliably measure cognition across postacute care settings and facilitate future studies of patient cognitive recovery.
Design. Rasch analysis of data from a prospective, observational cohort study.
Setting. Postacute care inclusive of inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies.
Participants. Patients (N=147) receiving rehabilitation services.
Interventions. Not applicable.
Main Outcome Measures. Functional Independence Measure, MDS 2.0, and the OASIS-B.
Results. Six cognition items demonstrated good construct validity with no misfitting items, unidimensionality, good precision (person separation reliability, 0.95), and an item hierarchy that reflected a clinically meaningful continuum of cognitive challenge.
Conclusions. This is the first attempt to combine the cognition items from the 3 historically, federally mandated assessments to create a common metric for cognition. These 6 items could be adopted as standardized patient assessment data elements to improve cognitive assessment across postacute care settings.

Archives of Physical Medicine and Rehabilitation, 101(12), 2071-2079. https://doi.org/10.1016/j.apmr.2020.06.030 Show abstract
Objectives. To identify areas of most restricted self-reported participation among veterans with traumatic brain injury (TBI), explore associations among participation restriction and clinical characteristics, and examine differences in participation restrictions by sex.
Design. Retrospective cross-sectional design.
Setting. National VA Polytrauma System of Care outpatient settings.
Participants. Veterans with a confirmed TBI event (N=6065).
Interventions. Not applicable.
Main Outcome Measure(s). Mayo-Portland Participation Index (M2PI), a 5-point Likert-type scale with 8 items. Total score was converted to standardized T score for analysis.
Results. The sample consisted of 5679 male and 386 female veterans with ≥1 clinically confirmed TBI events (69% white; 74% with blast exposure). The M2PI items with greatest perceived restrictions were social contact, leisure, and initiation. There were no significant differences between men and women on M2PI standardized T scores. Wilcoxon rank-sum analyses showed significant differences by sex on 4 items: leisure, residence, employment, and financial management (all P<.01). In multinomial logistic regression on each item controlling for demographics, injury characteristics, and comorbidities, female veterans had significantly greater relative risk for part-time work and unemployment on the employment item and significantly less risk for impairment on the residence and financial management item.
Conclusions. There was no significant difference between men and women. Veterans on M2PI standardized T scores, which masks differences in response patterns to individual items. Clinical teams should be encouraged to discuss perceived restrictions with patients and target these areas in treatment planning. Future work is needed to investigate the psychometric properties of the M2PI by biological sex.

This scoping study describes the range of outcomes in traumatic brain injury (TBI) studies of military service members and veterans addressing gender differences. A secondary purpose is to identify differences in outcomes between male and female participants in such studies. We searched PubMed, CiNAHL, and PsycInfo databases for relevant articles. Two reviewers independently screened results. Of 822 unique titles and abstracts screened for eligibility, 55 full articles were reviewed, with 29 studies meeting full inclusion criteria. Twenty of the 29 included studies used retrospective designs and all but two used data collected from Veterans Affairs or Department of Defense health care settings. TBI was diagnosed by self-report, screening, and evaluation procedures, and medical record documentation. Ten different outcome categories were identified among the included studies. In general, female service members and veterans have not been well represented in TBI outcomes research. Evidence suggests that female veterans with mild TBI (mTBI) report more neurobehavioral symptoms and use more outpatient services than male veterans. Studies also indicate that female veterans with TBI are more frequently diagnosed with depression. Additional research is essential to support precision treatment recommendations for female veterans with TBI, as women represent a growing proportion of the patients served by the Veterans Health Administration.

JAMA Network Open, 3(1), e1919672. https://doi.org/10.1001/jamanetworkopen.2019.19672 Show abstract
Importance. Medicare is shifting from payment for postacute care services based on the volume provided to payment based on value as determined by patient characteristics and functional outcomes. Matching therapy time and length of stay (LOS) to patient needs will be critical to optimize functional outcomes and manage costs.
Objective. To investigate the association among therapy time, LOS, and functional outcomes for patients following hip fracture surgery.
Design, Setting, and Participants. This retrospective cohort study analyzed data on patients from 4 inpatient rehabilitation facilities and 7 skilled nursing facilities in the eastern and midwestern United States. Participants were patients aged 65 years or older who received inpatient rehabilitation services for hip fracture and had Medicare fee-for-service as their primary payer. Data were collected from 2005 to 2010. Analysis was conducted from November 2018 to June 2019.
Exposure. Therapy minutes per LOS day.
Main Outcomes and Measures. Functional Independence Measure mobility and self-care measures at discharge. Patients were categorized into 9 recovery groups based on low, medium, or high therapy minutes per LOS day and low, medium, or high rate of functional gain per day.
Results. A total of 150 patients (101 [67.3%] female; 148 [98.6%] white; mean [SD] age, 82.0 [7.3] years) met inclusion criteria. Participants in all gain and therapy minutes per LOS day trajectories were similar in function at rehabilitation admission (mean [SD] mobility, 16.2 [3.2]; F8,141 = 1.26; P = .27) but differed significantly at discharge (mean [SD] mobility, 23.9 [5.2]; F8,141 = 14.34; P < .001). High-gain patients achieved mobility independence by discharge; low-gain patients needed assistance on nearly all mobility tasks. Medium-gain patients with a mean LOS of 27 days were independent in mobility at discharge; those with a mean LOS less than 21 days needed supervision with toilet transfers and were dependent with stairs. Length of stay and functional gain rate explained much of the variance in mobility and self-care scores at discharge. Although medium– and high–therapy minutes per LOS day groups were statistically significant in the regression model (β = 6.99; P = .001; and β = 11.46; P = .007, respectively), they explained only 1% of the variance in discharge outcome. Marginal means suggest that medium-gain patients with shorter LOS would have achieved mobility independence if LOS had been extended.
Conclusions and Relevance. In this study, rate of recovery and LOS in skilled nursing and inpatient rehabilitation facilities were associated with mobility and self-care outcomes at discharge following hip fracture surgery, particularly for medium-gain patients. Therapy time per day explained only 1% of the variance in discharge outcome. Discharging medium-gain patients before 21 days LOS may transfer burden of care to family and caregivers, home health, and outpatient services.

Purpose. Medically underserved adults with spinal cord injury (SCI) remain at high risk of incurring medically serious pressure injuries even after receiving education in prevention techniques. The purpose of this research is to identify circumstances leading to medically serious pressure injury development in medically underserved adults with SCI during a lifestyle-based pressure injury prevention program, and provide recommendations for future rehabilitation approaches and intervention design.
Methods. This study entailed a qualitative secondary case analysis of treatment notes from a randomized controlled trial. Participants were 25 community-dwelling, medically underserved adults with SCI who developed medically serious pressure injuries during the course of the intervention of the RCT.
Results and conclusions. Among the 25 participants, 40 unique medically serious pressure injuries were detected. The six themes related to medically serious pressure injury development were: (1) lack of rudimentary knowledge pertaining to wound care; (2) equipment and supply issues; (3) comorbidities; (4) non-adherence to prescribed bed rest; (5) inactivity; and (6) circumstances beyond the intervention’s reach. Together, these factors may have undermined the effectiveness of the intervention program. Modifications, such as assessing health literacy levels of patients prior to providing care, providing tailored wound care education, and focusing on equipment needs, have potential for altering future rehabilitation programs and improving health outcomes.

A growing number of individuals are living with chronic traumatic brain injury. As these individuals and their families attempt to reintegrate into their communities, several ethical questions arise for clinicians and researchers. These include issues around alignment of perspectives and priorities, as well as responsibilities for ongoing treatment, education, community outreach, and research. An action plan for addressing these questions is outlined.

The purpose of this study is to describe important features of occupational therapy practice for treatment of military service members with chronic symptoms and a history of mild traumatic brain injury (mTBI) in a military concussion care clinic from service members’ perspectives with support from occupational therapy practitioners. Two series of focus groups were conducted with service members with chronic mTBI-related symptoms (n = 6) and practitioners (n = 5). Data were analyzed concurrently with collection. We identified five main themes: therapeutic relationship, consistent inclusion of family members, combat versus noncombat injuries, loss of military identity, and assessment against population norms. The findings of this study suggest that service members’ evaluations of occupational therapy are based on the overall experience of the encounter, centered by the therapeutic relationship, rather than specific intervention strategies or technology.

Importance. Pregnancy loss and infant death are unexpected, traumatic, life-changing events. The role of occupational therapy practitioners in treating this population is not well defined.
Objective. To describe the outcomes of an occupation-based residential retreat for women who have experienced pregnancy or infant loss.
Design. Program evaluation.
Setting. Seven residential retreats for bereaved mothers.
Participants. One hundred forty-one women who experienced perinatal loss.
Intervention. Residential retreats that were held in natural settings and included occupation-based activities such as group discussions, yoga, meditation, crafts, and rituals to facilitate grieving and healing processes after perinatal loss.
Outcomes and Measures. The Beck Depression Inventory, PTSD Checklist–Civilian Version, Self-Compassion Scale, and Multidimensional Scale of Perceived Social Support were collected pre- and postretreat.
Results. Statistically significant improvements were seen in women’s depression, trauma, self-compassion, and perceived social support from pre- to postretreat.
Conclusions and Relevance. At present, occupational therapy practitioners support this population primarily by providing referrals and information about local resources. However, as occupational therapy practice in primary care settings grows, so too do possibilities for the development of occupational therapy–related interventions to support maternal mental health.
What This Article Adds. This article provides preliminary support for occupation-based retreats as a treatment for improving maternal mental health after perinatal loss.

Objective. The purpose of this study was to identify the needs of military service members with chronic symptoms after mild traumatic brain injury (mTBI) that fall within the scope of occupational therapy practice.
Method. In this qualitative descriptive study, service members with a history of mTBI (N = 12) participated in semistructured interviews about their injury history, symptoms, daily routines, challenges, and plans.
Results. Two main themes were identified: occupational changes and plans for the future. Occupational changes contains six subthemes: (1) rest and sleep, (2) activities of daily living and instrumental activities of daily living, (3) work, (4) social participation, (5) play and leisure, and (6) education. Plans for the future contains three subthemes: (1) supports, (2) barriers, and (3) fears.
Conclusion. Occupational therapists who work with this population should consider all areas of occupation, especially sleep, during assessment and treatment planning. Some clients may require additional support for preparing for civilian life.

Topics in Spinal Cord Injury Rehabilitation, 25(1), 31-40. https://doi.org/10.1310/sci2501-31 Show abstract
Background. Pressure injuries negatively impact quality of life and participation for individuals with spinal cord injury (SCI).
Objective. To examine the factors that may protect against the development of medically serious pressure injuries in adults with SCI.
Methods. A qualitative analysis was conducted using treatment notes regarding 50 socioeconomically disadvantaged individuals who did not develop medically serious pressure injuries during a 12-month pressure injury prevention intervention program.
Results. Eight types of potentially protective factors were identified: meaningful activity, motivation to prevent negative health outcomes, stability/resources, equipment, communication and self-advocacy skills, personal traits, physical factors, and behaviors/activities.
Conclusions. Some protective factors (e.g., personal traits) may be inherent to certain individuals and nonmodifiable. However, future interventions for this population may benefit from a focus on acquisition of medical equipment and facilitation of sustainable, health-promoting habits and routines. Substantive policy changes may be necessary to facilitate access to adequate resources, particularly housing and equipment, for socioeconomically disadvantaged individuals with SCI. Further research is needed to understand the complex interplay of risk and protective factors for pressure injuries in adults with SCI, particularly in underserved groups.

Context/Objective. Medically serious pressure injuries (MSPrIs), a common complication of spinal cord injury (SCI), have devastating consequences on health and well-being and are extremely expensive to treat. We aimed to test the efficacy of a lifestyle-based intervention designed to reduce incidence of MSPrIs in adults with SCI.
Design. A randomized controlled trial (RCT), and a separate study wing involving a nonrandomized standard care control group.
Setting. Rancho Los Amigos National Rehabilitation Center, a large facility serving ethnically diverse, low income residents of Los Angeles County.
Participants. Adults with SCI, with history of one or more MSPrIs over the past 5 years: N=166 for RCT component, N=66 in nonrandomized control group.
Interventions. The Pressure Ulcer Prevention Program, a 12-month lifestyle-based treatment administered by healthcare professionals, largely via in-home visits and phone contacts.
Outcome Measures. Blinded assessments of annualized MSPrI incidence rates at 12 and 24 months, based on: skin checks, quarterly phone interviews with participants, and review of medical charts and billing records. Secondary outcomes included number of surgeries and various quality-of-life measures.
Results. Annualized MSPrI rates did not differ significantly between study groups. At 12 months, rates were .56 for intervention recipients, .48 for randomized controls, and .65 for nonrandomized controls. At follow-up, rates were .44 and .39 respectively for randomized intervention and control participants.
Conclusions. Evidence for intervention efficacy was inconclusive. The intractable nature of MSPrI threat in high-risk SCI populations, and lack of statistical power, may have contributed to this inability to detect an effect.

Purpose. Participation is widely recognized as an important outcome for rehabilitation. However, it lacks a universally accepted definition. The purpose of this review is to synthesize the literature about participation in rehabilitation in order to clarify the term and increase its usefulness for rehabilitation providers and researchers.
Methods. We undertook an interpretive synthesis of the literature, drawing from a broad and varied selection of the vast number of publications on the subject of participation. The search and analysis was iterative and continued until saturation of themes was achieved.
Results and Conclusions. Seventy-six articles were included in our analysis. We argue that three essential dimensions — performance, subjective experience, and interpersonal connection — constitute participation. We further divide participation into community-based and interventional contexts. Interventional participation is circumscribed by the treatment setting, whereas community-based encompasses all other areas. Participation in either interventional or community-based contexts is largely determined by the available opportunities from which a person can choose, with such opportunities affected by conditions that are either internal or external to the individual. As defined in this framework, participation is not inherently good or bad; rather, its effect is determined by a person's unique life circumstances and the impact may not always be apparent. We posit this model as a resource for future research as well as clinical reasoning.
Implications for Rehabilitation. The often tacit assumption that increasing participation is a desirable outcome needs to be challenged and considered in each patient's life situation. Treatment settings constitute a unique context in which patients participate. Intervention goals should be clearly connected with patients' personal goals for community-based participation.
Cogan, A. (2016). From surviving to flourishing: Using narrative as a tool for patient-centered care. Journal of Humanities in Rehabilitation. Full text Show abstract
Rehabilitation practice aims to restore people to health after injury or illness. Health involves not only managing the technical aspects of treating the condition, but also living a good and personally fulfilling life. In addition to biomedical management, attention to flourishing – or fulfillment of one’s potential – requires intentional and individualized intervention. Clinicians can use narrative to better understand patient needs and values to encourage such a patient-centered approach to care. The purpose of this article is to describe the benefits of developing skills for understanding and interpreting stories, i.e. “narrative competence”, through reading and analyzing published first-person illness narratives. I will illustrate this approach by examining a story about a journey excerpted from memoirs written by a patient and caregiver dyad; then, contrasting between biomedical and narrative analyses of the story, demonstrate how the latter can enhance clinical reasoning for rehabilitation practice. This approach has the potential to generate new skills for rehabilitation clinicians that can help all patients flourish, regardless of disability.
Keywords. Narrative, patient-centered care, competencies, clinical reasoning

Mild traumatic brain injury (mTBI) has been labeled the “signature injury” of the wars in Iraq and Afghanistan, and approximately half of mTBIs that occur in combat are due to explosive blasts. The rapid change in pressure that results from an explosion may make blast injury distinct from mTBI due to other causes. Persistent symptoms following blast mTBI may be related to white matter damage that has recently been identified using innovative neuroimaging techniques, such as diffusion tensor imaging (DTI). By comparing the DTI findings in blast mTBI to studies of the effects of white matter structure on functional performance, hypotheses can be developed about the implications of the injury for engagement in occupation. Incorporation of neuroscience evidence about the effects of blast mTBI may provide objective evidence of underlying damage that correlates with deficits in occupational engagement of military service members and veterans who are affected by these injuries.

Objective. To investigate the efficacy of behavioral or educational interventions in preventing pressure ulcers in community-dwelling adults with spinal cord injury (SCI).
Data Sources. Cochrane, Clinical Trials, PubMed, and Web of Science were searched in June 2016. The search combined related terms for pressure ulcers, spinal cord injury, and behavioral intervention. Each database was searched from its inception with no restrictions on year of publication.
Review Methods. Inclusion criteria required that articles were (a) published in a peer-reviewed journal in English, (b) evaluated a behavioral or educational intervention for pressure ulcer prevention, (c) included community-dwelling adult participants aged 18 years and older with SCI, (d) measured pressure ulcer occurrence, recurrence, or skin breakdown as an outcome, and (e) had a minimum of 10 participants. All study designs were considered. Two reviewers independently screened titles and abstracts. Extracted information included study design, sample size, description of the intervention and control condition, pressure ulcer outcome measures, and corresponding results.
Results. The search strategy yielded 444 unique articles of which five met inclusion criteria. Three were randomized trials and two were quasi-experimental designs. A total of 513 participants were represented. The method of pressure ulcer or skin breakdown measurement varied widely among studies. Results on pressure ulcer outcomes were null in all studies. Considerable methodological problems with recruitment, intervention fidelity, and participant adherence were reported.
Conclusions. At present, there is no positive evidence to support the efficacy of behavioral or educational interventions in preventing pressure ulcer occurrence in adults with SCI.

This paper argues the benefits of characterizing occupational transitions as movement between figured worlds, which are socially constructed units that are characterized by particular people and activities, and that shape identities. Further, positive withdrawal, which is a purposeful decision to limit participation when the requirements of engaging surpass self-perceived ability, describes limited engagement with a figured world. To illustrate the utility of this lens, the community reintegration of military service members as they finish deployment and return to family and community life is explored. The figured worlds of military and family are drawn from first person accounts of deployment and reintegration experiences from the perspectives of both service members and spouses. The constructs of figured world and positive withdrawal are found to be useful ways to describe community reintegration for both service members and families and the complex shifts in identity associated with the transition process. The framework presented expands on the occupational science literature by presenting a framework for non-linear, bidirectional occupational transitions in which individuals return to familiar settings rather than enter novel ones. The constructs of figured world and positive withdrawal can contribute to future theory development and research with populations that experience similar occupational transitions.

Reorganized, expanded, and updated, this new edition of the award-winning Lifestyle Redesign gives practical guidance in this preventative occupational therapy program for independent-living older adults. The work integrates the concept of the USC's landmark Well Elderly Studies, which determined that preventive occupational therapy greatly enhances the health and quality of life of independent-living older adults.
Twelve modules, including those on longevity, stress, home safety and navigating health care, illustrate how to incorporate the program into practice. Includes a flash drive with program handouts.

Implementation into real-world practice of interventions previously studied in randomized controlled trials is an ongoing challenge. In this article, we describe the methodology we used for the first phase of a project for the implementation and outcomes assessment of an occupational therapy pressure ulcer prevention intervention for people with spinal cord injury in the Veterans Health Administration. This first phase of the project was guided by practice-based evidence research methodology and resulted in an intervention manual tailored to meet the needs of Veterans and the establishment of a system for documenting and monitoring care processes, patient characteristics, and intervention outcomes. This system, in turn, will provide the data-gathering template for the next phase in which the beneficial effects of the intervention will be assessed. We conclude by recommending that clinicians explore the utility of this approach for the implementation of other novel interventions.

More than 2 million U.S. military servicemembers have deployed to Afghanistan or Iraq since September 11, 2001. Unlike during prior conflicts, many servicemembers leave spouses and children behind. Long, multiple deployments cause strain on family at home, with new challenges arising when servicemembers return from combat and reintegrate into family and civilian life. In World Wars I and II, occupational therapy practitioners played a significant role in supporting servicemember reintegration. However, their presence in program delivery in this practice area is limited. Occupational therapy researchers and practitioners can make a valuable contribution by helping families tailor daily activities and routines to address challenges and optimize health and wellness. However, barriers such as reimbursement for services, workforce availability, and access to military families have limited the profession’s full engagement. Advocacy is needed to help establish occupational therapy as a key component of the mental and preventive health care teams serving military servicemembers.

Mild traumatic brain injury (mTBI), also known as concussion, has been labeled the “signature injury” of the wars in Iraq and Afghanistan. A subset of military personnel with mTBI experience ongoing symptoms well beyond the normal recovery window. While much research has been dedicated to understanding the etiology and severity of the symptoms, very little has assessed how long-term symptoms impact participation in daily life. A scoping study of the occupational science and occupational therapy literature was conducted to ascertain the current state of research on the impact of mTBI on participation in daily life activities, as well as occupational therapy interventions for mTBI. Although the emphasis in this article is on military personnel with mTBI, studies on civilians with mTBI were included in the review as research with military populations is extremely limited. Based on the literature reviewed, the author suggests a role for occupational science research and occupational therapy practice in meeting the occupational needs of military service members with persistent symptoms after mTBI.
