Context: Prognostic prediction models (PPMs) can help clinicians predict outcomes., Objective: To critically examine peer-reviewed PPMs predicting delayed recovery among pediatric patients with concussion., Data Sources: Ovid Medline, Embase, Ovid PsycInfo, Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Google Scholar., Study Selection: The study had to report a PPM for pediatric patients to be used within 28 days of injury to estimate risk of delayed recovery at 28 days to 1 year postinjury. Studies had to have at least 30 participants., Data Extraction: The Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies checklist was completed., Results: Six studies of 13 PPMs were included. These studies primarily reflected male patients in late childhood or early adolescence presenting to an emergency department meeting the Concussion in Sport Group concussion criteria. No study authors used the same outcome definition nor evaluated the clinical utility of a model. All studies demonstrated high risk of bias. Quality of evidence was best for the Predicting and Preventing Postconcussive Problems in Pediatrics (5P) clinical risk score., Limitations: No formal PPM Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) process exists., Conclusions: The 5P clinical risk score may be considered for clinical use. Rigorous external validations, particularly in other settings, are needed. The remaining PPMs require external validation. Lack of consensus regarding delayed recovery criteria limits these PPMs., (Copyright © 2024 by the American Academy of Pediatrics.)

Comparing self-reported symptom scores across time requires longitudinal measurement invariance (LMI), a psychometric property that means the measure is functioning identically across all time points. Despite its prominence as a measure of depression symptom severity in both research and health care, LMI has yet to be firmly established for the Patient Health Questionnaire-9 depression module (PHQ-9), particularly over the course of antidepressant pharmacotherapy. Accordingly, the objective of this study was to assess for LMI of the PHQ-9 during pharmacotherapy for major depressive disorder. This was a secondary analysis of data collected during a randomized controlled trial. A total of 1,944 veterans began antidepressant monotherapy and completed the PHQ-9 six times over 24 weeks of treatment. LMI was assessed using a series of four confirmatory factor analysis models that included all six time points, with estimated parameters increasingly constrained across models to test for different aspects of invariance. Root-mean-square error of approximation of the chi-square difference test values below 0.06 indicated the presence of LMI. Exploratory LMI analyses were also performed for separate sex, age, and race subgroups. Root-mean-square error of approximation of the chi-square difference test showed minimal change in model fits during invariance testing (≤ 0.06 for all steps), supporting full LMI for the PHQ-9. LMI was also supported for all tested veteran subgroups. As such, PHQ-9 sum scores can be compared across extended pharmacotherapy treatment durations.

As health care attempts to bridge the gap between evidence and practice, the concept of the learning health system (LHS) is becoming increasingly relevant. LHS integrates evidence with health systems data, driving health care quality and outcomes through updates in policy, practice, and care delivery. In addition, LHS research is becoming critically important as there are several initiatives underway to increase research capacity, expertise, and implementation, including attempts to stimulate increasing numbers of LHS researchers. Physical Medicine & Rehabilitation (PM&R) physicians (physiatrists), nurses, therapists (physical therapists, occupational therapists, speech therapists, clinical psychologists), and scientists are affiliated with LHSs. As LHS research expands in health care systems, better awareness and understanding of LHSs and LHS research competencies are key for rehabilitation professionals including physiatrists. To address this need, the Agency of Healthcare Research and Quality (AHRQ) identified 33 core competencies, grouped into eight domains, for training LHS researchers. The domains are: (1) Systems Science; (2) Research Questions and Standards of Scientific Evidence; (3) Research Methods; (4) Informatics; (5) Ethics of Research and Implementation in Health Systems; (6) Improvement and Implementation Science; (7) Engagement, Leadership, and Research Management; and the recently added (8) Health and Healthcare Equity and Justice. The purpose of this commentary is to define LHS and its relevance to physiatrists, present the role of implementation science (IS) in LHSs and application of IS principles to design LHSs, illustrate current LHS research in rehabilitation, and discuss potential solutions to improve awareness and to stimulate interest in LHS research and IS among physiatrists in LHSs., (© 2024 The Authors.

Objective: We sought to elicit key informant (KI) perspectives regarding decisional needs of Veterans with mild traumatic brain injury (mTBI) who are initiating insomnia disorder and obstructive sleep apnea (OSA) treatment within the Veterans Health Administration (VHA) Polytrauma/TBI System of Care (PSC). Specifically, we sought to understand: (1) information regarding treatment options that Veterans with mTBI require in order to make an informed decision; and (2) values used to guide decision-making (ie, personally meaningful aspects of the decision used to compare treatment options)., Setting: Nationwide VHA PSC sites., Participants: Clinicians included VHA providers and policymakers involved in the management of mTBI and/or sleep disorders in the VHA PSC (n = 29). Veterans included those with a clinician-confirmed mTBI who received care for insomnia disorder and/or OSA within the past year (n = 20)., Design: Semi-structured interviews with the 49 KIs were recorded and transcribed verbatim. Themes were identified using a descriptive and interpretive approach to qualitative analysis., Main Measures: Not applicable., Results: Informational needs identified by both KI groups included information regarding outcomes and downsides of treatment, accessible delivery, treatment candidates, description of diagnosis, and level of commitment. Values used to guide decision-making for both insomnia disorder and OSA treatment included benefits, downsides, and availability of treatments. Values used to decide on insomnia treatments alone included time commitment, intrinsic management of sleep, beliefs regarding mental health treatment, and time course of benefit. Values used to decide on OSA treatment alone included intrusiveness of the treatment, appearance, and impact on bed partners., Conclusions: The current study revealed the decisional needs of Veterans with mTBI who are initiating sleep disorder treatment. Findings can inform the development of decision aids and other efforts aimed at promoting patient-centered management of comorbid mTBI and sleep disorders, thereby improving care quality and clinical outcomes., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Importance: Veterans receiving inpatient psychiatric services with limitations in activities of daily living (ADLs) benefit from occupational therapy, yet disparities in access are unknown., Objective: To investigate whether ADL limitations, an indicator of occupational therapy need, was associated with inpatient psychiatric occupational therapy utilization in the Veterans Health Administration (VHA) and whether this relationship differs by facility characteristics., Design: Secondary analysis of VHA data. Modified Poisson regression modeled occupational therapy utilization as a function of ADL limitations, facility characteristics, and covariates. Interactions estimated whether the relationship between ADL limitations and occupational therapy utilization differed across facility characteristics., Setting: VHA inpatient psychiatric setting., Participants: Veterans receiving VHA inpatient psychiatric care from 2015 to 2020 (N = 133,844)., Outcomes and Measures: Occupational therapy utilization., Results: Veterans with ADL limitations were more likely to receive occupational therapy. Veterans receiving care in facilities with higher complexity and greater inpatient psychiatric care quality were more likely to receive occupational therapy. Additionally, Black veterans were less likely to receive occupational therapy relative to their White, non-Hispanic counterparts. Interactions indicated that the extent to which ADL limitations drove access to occupational therapy utilization was weaker within facilities with higher complexity and care quality., Conclusions and Relevance: Veterans with ADL limitations were more likely to access inpatient psychiatric occupational therapy, suggesting that such services are generally allocated to veterans in need. However, findings indicate disparities in access across patient-level (e.g., Black race) and facility-level (e.g., facility complexity) factors, informing efforts to eliminate barriers to accessing these valuable services. Plain-Language Summary: This is the first study, to our knowledge, to examine disparities in access to inpatient psychiatric occupational therapy in the Veterans Health Administration (VHA). The study findings show that access to inpatient psychiatric occupational therapy is partly driven by the needs of the patient. However, nonclinical factors, such as a patient's race and the characteristics of the facility at which they receive care (complexity, number of psychiatric beds available, and the quality of psychiatric care), are also important drivers of access. Identifying factors influencing access to these valuable services is the first step in developing strategies that reduce barriers to access for veterans in need., (Copyright © 2024 by the American Occupational Therapy Association, Inc.)

Objective: To identify distinct subgroups of veterans with mild traumatic brain injury (mTBI) based on configurations of postconcussive symptom (PCS) endorsement, and to examine predictors of subgroup membership., Setting: Outpatient Veterans Health Administration (VHA)., Participants: Veterans with clinician-confirmed mTBI who completed the Neurobehavioral Symptom Inventory (NSI), determined using the Comprehensive Traumatic Brain Injury Evaluation database. Individuals who tended to overreport symptoms were excluded via an embedded symptom validity scale., Design: Retrospective cohort study leveraging national VHA clinical data from 2012 to 2020. Latent class analysis (LCA) with a split-sample cross-validation procedure was used to identify subgroups of veterans. Multinomial logistic regression was used to examine predictors of subgroup membership., Main Measures: Latent classes identified using NSI items., Results: The study included 72 252 eligible veterans, who were primarily White (73%) and male (94%). The LCA supported 7 distinct subgroups of veterans with mTBI, characterized by diverging patterns of risk for specific PCS across vestibular (eg, dizziness), somatosensory (eg, headache), cognitive (eg, forgetfulness), and mood domains (eg, anxiety). The most prevalent subgroup was Global (20.7%), followed by Cognitive-Mood (16.3%), Headache-Cognitive-Mood (H-C-M; 16.3%), Headache-Mood (14.2%), Anxiety (13.8%), Headache-Sleep (10.3%), and Minimal (8.5%). The Global class was used as the reference class for multinomial logistic regression because it was distinguished from others based on elevated risk for PCS across all domains. Female (vs male), Black (vs White), and Hispanic veterans (vs non-Hispanic) were less likely to be members of most subgroups characterized by lesser PCS endorsement relative to the Global class (excluding Headache-Mood)., Conclusion: The 7 distinct groups identified in this study distill heterogenous patterns of PCS endorsement into clinically actionable phenotypes that can be used to tailor clinical management of veterans with mTBI. Findings reveal empirical support for potential racial, ethnic, and sex-based disparities in PCS among veterans, informing efforts aimed at promoting equitable recovery from mTBI in this population., Competing Interests: The authors declare no conflicts of interest.

Objective: To understand factors influencing adherence to recommended treatment for insomnia and obstructive sleep apnea (OSA) among Veterans with mild traumatic brain injury (mTBI)., Method: Semi-structured interviews ( n  = 49) with 29 clinical stakeholders and 20 Veterans were conducted. Clinical stakeholders included Veterans Health Administration providers and policymakers involved in the management of mTBI and/or sleep disorders. Veterans included those with a clinician-confirmed mTBI with a recent history of insomnia disorder and/or OSA treatment. Themes were identified using a Descriptive and Interpretive approach., Results: Barriers to sleep disorder treatment adherence included factors associated with the patient (e.g., negative appraisal of treatment benefit), intervention (e.g., side effects), health conditions (e.g., cognitive challenges), health care system (e.g., limited availability of care), and socioeconomic status (e.g., economic instability). Similarly, facilitators of adherence included patient- (e.g., positive appraisal of treatment benefit), intervention- (e.g., flexible delivery format), condition- (e.g., accommodating cognitive impairments), health care system- (e.g., access to adherence support), and socioeconomic-related factors (e.g., social support)., Conclusions: Interviews revealed the multi-faceted nature of factors influencing adherence to sleep disorder treatment among Veterans with mTBI. Findings can inform the development of novel interventions and care delivery models that meet the complex needs of this population.

Background: Individuals with a history of moderate-severe traumatic brain injury (TBI) experience a significantly higher prevalence of insomnia compared to the general population. While individuals living with TBI have been shown to benefit from traditional insomnia interventions (e.g., face-to-face [F2F]), such as Cognitive Behavioral Therapy for Insomnia (CBTI), many barriers exist that limit access to F2F evidence-based treatments. Although computerized CBT-I (CCBT-I) is efficacious in terms of reducing insomnia symptoms, individuals with moderate-severe TBI may require support to engage in such treatment. Here we describe the rationale, design, and methods of a randomized controlled trial (RCT) assessing the efficacy of a guided CCBT-I program for reducing insomnia symptoms for participants with a history of moderate-severe TBI., Methods: This is an RCT of a guided CCBT-I intervention for individuals with a history of moderate-severe TBI and insomnia. The primary outcome is self-reported insomnia severity, pre- to post-intervention. Exploratory outcomes include changes in sleep misperception following CCBT-I and describing the nature of guidance needed by the Study Clinician during the intervention., Conclusion: This study represents an innovative approach to facilitating broader engagement with an evidence-based online treatment for insomnia among those with a history of moderate-severe TBI. Findings will provide evidence for the level and nature of support needed to implement guided CCBT-I. Should findings be positive, this study would provide support for a strategy by which to deliver guided CCBT-I to individuals with a history of moderate-severe TBI., Competing Interests: Declaration of competing interest Dr. Brenner reports grants from the VA, DOD, NIH, and the State of Colorado, editorial renumeration from Wolters Kluwer, and royalties from the American Psychological Association and Oxford University Press.

There is a rare subset of patients with a genetically abnormal hemoglobin structure initially discovered in the Volga region of Europe known as Volga anemia. Key features of this condition include compromised delivery of oxygen to peripheral tissues and altered red blood cells that have a higher likelihood of being broken down or hemolyzed, which can lead to significant hemolytic anemia. Methylene blue is a dye that acts as a reducing agent of oxygen and is commonly used in toxic states that lead to methemoglobin build-up. This paper explores the pathophysiology of this genetic condition and documents three cases across two patients-a father and son-when methylene blue was used during an anemic crisis., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

Objective: The authors sought to investigate whether utilization of inpatient occupational therapy (OT) was associated with reduced risk for 30-day psychiatric readmission in the Veterans Health Administration (VHA)., Methods: The authors conducted a secondary analysis of VHA medical record data for veterans who received inpatient psychiatric care from 2015 to 2020 (N=176,889). Mixed-effects logistic regression was used to model psychiatric readmission within 30 days of discharge (yes or no) as a function of inpatient psychiatric OT utilization (none, one, two, three, or four or more encounters) and other care utilization (e.g., previous psychiatric hospitalization), as well as clinical (e.g., primary diagnosis), sociodemographic (e.g., race-ethnicity), and facility (e.g., complexity) characteristics. Sensitivity analyses were conducted to evaluate the robustness of findings (e.g., stratification by discharge disposition)., Results: Relatively few veterans received inpatient psychiatric OT (26.2%), and 8.4% were readmitted within 30 days. Compared with veterans who did not receive inpatient psychiatric OT, those with one (OR=0.76), two (OR=0.64), three (OR=0.67), or four or more encounters (OR=0.64) were significantly (p<0.001) less likely to be readmitted within 30 days. These findings were consistent across all sensitivity analyses., Conclusions: Veterans who received inpatient OT services were less likely to experience psychiatric readmission. A clear dose-response relationship between inpatient psychiatric OT and readmission risk was not identified. These findings suggest that OT services may facilitate high-value inpatient psychiatric care in the VHA by preventing readmissions that stymie recovery and incur high costs. Future research may establish the causality of this relationship, informing policy regarding increased access to inpatient psychiatric OT., Competing Interests: Dr. Brenner reports editorial remuneration from Wolters Kluwer and RAND, royalties from the American Psychological Association and Oxford University Press, and consulting for sports leagues.

Study Objectives: We elicited perspectives of clinical stakeholders and Veterans regarding barriers and facilitators to implementing shared decision-making (SDM) for comorbid mild traumatic brain injury (mTBI) and sleep disorders in the Veterans Health Administration. We also compared the perspectives of clinical stakeholders and Veterans regarding determinants of SDM., Methods: Semistructured interviews were conducted with 29 clinical stakeholders and 20 Veterans (n = 49). Clinical stakeholders included Veterans Health Administration providers and policymakers involved in the management of mTBI and/or sleep disorders (insomnia disorder, obstructive sleep apnea). Veterans included those with a clinician-confirmed mTBI who received care for insomnia disorder and/or obstructive sleep apnea within the past year. Themes were identified using a descriptive and interpretive approach to qualitative analysis. We compared results across clinical stakeholders and Veterans., Results: Barriers to implementing SDM were identified by both groups at the patient (eg, mTBI sequalae), provider (eg, deprioritization of Veteran preferences), encounter (eg, time constraints), and facility levels (eg, reduced care access). Similarly, both groups identified facilitators at the patient (eg, enhanced trust), provider (eg, effective communication), encounter (eg, decision support), and facility levels (eg, mitigating access barriers). Integrated services and provider discontinuity were factors identified by clinical stakeholders and Veterans alone, respectively., Conclusions: Our study revealed factors shaping the implementation of SDM at the levels of the patient, provider, encounter, and facility. Findings can inform the development of strategies aimed at implementing SDM for comorbid mTBI and sleep disorders, promoting patient-centered care and enhancing clinical outcomes., Citation: Kinney AR, Brenner LA, Nance M, et al.

Objective: Latent class analysis was used to identify functional classes among patients hospitalized for pneumonia. Then, we determined predictors of class membership and examined variation in distal outcomes among the functional classes., Design: An observational, cross-sectional study design was used with retrospectively collected data between 2014 and 2018., Setting: The study setting was a single health system including 5 acute care hospitals., Participants: A total of 969 individuals hospitalized with the primary diagnosis of pneumonia and receipt of an occupational and/or physical therapy evaluation were included in the study., Interventions: Not applicable., Main Outcomes: The following 5 distal outcomes were examined: (1) occupational therapy treatment use, (2) physical therapy treatment use, (3) discharge to home with no services, (4) discharge to home with home health, and (5) institutional discharge., Results: Five functional classes were identified and labeled as follows: Globally impaired, Independent with low-level self-care, Independent low-level mobility, Independent self-care, and Independent . Probability of occupational therapy treatment use (χ 2 [4]=50.26, P <.001) and physical therapy treatment use (χ 2 [4]=50.86, P <.001) varied significantly across classes. The Independent with low-level self-care class had the greatest probability of occupational therapy treatment use and physical therapy treatment use. Probability of discharging to home without services (yes/no; χ 2 [4]=88.861, P <.001), home with home health (yes/no; χ 2 [4]=15.895, P =.003), and an institution (yes/no; χ 2 [4]=102.013, P <.001) varied significantly across the 5 classes. The Independent class had the greatest probability of discharging to home without services., Conclusions: Five functional classes were identified among individuals hospitalized for pneumonia. Functional classes could be used by the multidisciplinary team in the hospital as a framework to organize the heterogeneity of functional deficits after pneumonia, improve efficiency of care processes, and help deliver targeted rehabilitation treatment., (© 2024 The Authors.)

Objective: To investigate whether participation restrictions, an indicator of need for occupational therapy (OT), was associated with outpatient OT utilization in the Veterans Health Administration (VHA) among Veterans with mild traumatic brain injury (mTBI), and whether this relation differs by facility characteristics., Design: In a secondary analysis of national VHA data, we used modified Poisson regression to model OT utilization (yes/no) as a function of participation restrictions (Mayo-Portland Adaptability Inventory Participation Index [M2PI]), facility characteristics, and covariates. Facility characteristics included complexity, geographic region, and self-reported access to specialty care. Covariates included prior OT utilization, sociodemographic factors, injury characteristics, and spatial access (eg, drive time). Interactions estimated whether the relation between participation restrictions and OT utilization differed across facility characteristics., Setting: Outpatient setting in the VHA., Participants: 8684 Veterans with a clinician-confirmed mTBI who received outpatient VHA care between 2012 and 2020 (N=8684)., Interventions: None., Main Outcome Measure(s): OT utilization was measured within a year of M2PI administration using VHA administrative data., Results: Many Veterans who did not receive OT reported participation limitations, indicating unmet need for OT (eg, 67% with leisure restrictions). Participation restrictions were associated with increased likelihood of receiving OT (risk ratio [RR]=1.01; 95% confidence interval [CI]=1.006-1.019), suggesting a tendency for Veterans' OT-related needs to be satisfied. However, interactions indicated that this was not the case among Veterans receiving care in lower complexity facilities, and those in the South. Veterans with longer drive times were less likely to receive OT (RR=0.82; 95% CI=0.744-0.904)., Conclusions: Participation restrictions were associated with OT utilization, yet many Veterans with mTBI who may have benefited did not receive such care. Specific barriers to accessing OT (eg, OT practitioner supply) should be investigated. Novel care models can ensure access to OT services among Veterans seeking care at less-resourced and/or geographically distant VHA facilities., (Published by Elsevier Inc.)

Occupational therapy has been identified as a required service in the neuro critical care unit (NCCU), however who receives occupational therapy services and what services they receive are not well understood. We sought to determine if arousal deficits impacted patients' likelihood to receive an occupational therapy evaluation or specific types of occupational therapy interventions in the NCCU. When compared to patients without arousal deficits, patients who were experiencing agitation or light sedation, but not deep sedation, were more likely to receive occupational therapy interventions in the therapeutic activities category. Arousal deficits were not associated with receipt of occupational therapy services or occupational therapy interventions in the self-care or therapeutic exercise categories. Determining predictors of occupational therapy services will help ensure the timely delivery of services by improving the allocation of resources and identifying potential gaps in care.

Objective: Synthesize data regarding barriers and facilitators of adoption (ie, adoption determinants) of evidence-based occupational (OT) and physical therapy (PT) interventions within real-world practice. Whether evidence varied across disciplines, settings, and use of theoretical frameworks was also examined., Data Sources: Literature published from database inception to December 9, 2022, in OVID MEDLINE, EMBASE, OVID PsycINFO, Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and Google Scholar., Study Selection: Original research including: (1) stakeholder insight into adoption determinants; (2) discrete evidence-based interventions delivered/supervised by an OT and/or PT; (3) intervention recipients aged 18 or older; and (4) data regarding adoption determinants. Two reviewers independently screened and evaluated studies for inclusion, with a third resolving discrepancies. Of the 3036 articles identified, 45 articles were included., Data Extraction: Data were extracted by a primary reviewer, independently evaluated by a second reviewer, and conflicts were resolved via group consensus., Data Synthesis: A descriptive synthesis approach was used to categorize adoption determinants according to constructs from the Consolidated Framework for Implementation Research. 87% of studies were published after 2014. Many studies: described PT interventions (82%); were within the outpatient setting (44%); had data gathered after implementing the intervention (71%); and did not report use of a theoretical framework to inform data collection (62%). Lack of available resources (64%) and knowledge/beliefs about the intervention (53%) were the most common barrier and facilitator, respectively. Variability in adoption determinants was observed according to discipline, setting, and use of a theoretical framework., Conclusions: Findings suggest a recent surge of scientific investment in understanding adoption determinants for evidence-based OT and PT interventions. Such knowledge can inform efforts aimed at improving OT and PT quality, thereby enhancing patient outcomes. However, our review highlighted gaps with significant implications for the delivery of evidence-based OT and PT within real-world practice settings., (Published by Elsevier Inc.)

Objective: Among service members (SMs) with mild traumatic brain injury (mTBI) admitted to an intensive outpatient program (IOP), we identified qualitatively distinct subgroups based on post-concussive symptoms (PCSs) and characterized changes between subgroups from admission to discharge. Further, we examined whether co-morbid posttraumatic stress disorder (PTSD) influenced changes between subgroups., Design: Quasi-experimental. Latent transition analysis identified distinctive subgroups of SMs and examined transitions between subgroups from admission to discharge. Logistic regression examined the effect of PTSD on transition to the Minimal subgroup (low probability of any moderate-very severe PCS) while adjusting for admission subgroup designation., Setting: National Intrepid Center of Excellence (NICoE) at Walter Reed National Military Medical Center., Participants: 1141 active duty SMs with persistent PCS despite prior treatment (N=1141)., Interventions: NICoE 4-week interdisciplinary IOP., Main Outcome Measure(s): Subgroups identified using Neurobehavioral Symptom Inventory items at admission and discharge., Results: Model fit indices supported a 7-class solution. The 7 subgroups of SMs were distinguished by diverging patterns of probability for specific PCS. The Minimal subgroup was most prevalent at discharge (39.4%), followed by the Sleep subgroup (high probability of sleep problems, low probability of other PCS; 26.8%). 41% and 25% of SMs admitted within the Affective (ie, predominantly affective PCS) and Sleep subgroups remained within the same group at discharge, respectively. The 19% of SMs with co-morbid PTSD were less likely to transition to the Minimal subgroup (odds ratio=0.28; P<.001) and were more likely to remain in their admission subgroup at discharge (35.5% with PTSD vs 22.2% without)., Conclusions: Most of SMs achieved symptom resolution after participation in the IOP, with most transitioning to subgroups characterized by reduced symptom burden. SMs admitted in the Affective and Sleep subgroups, as well as those with PTSD, were most likely to have continuing clinical needs at discharge, revealing priority targets for resource allocation and follow-up treatment., (Published by Elsevier Inc.)

Background: Justice-involved Veterans experience notable risk for psychosocial stressors (e.g., homelessness) and psychiatric multimorbidity, which can result in complex clinical presentations. However, research examining how such factors coalesce to impact risk for suicide remains limited., Methods: We conducted a latent class analysis of 180,454 Veterans accessing Veterans Health Administration (VHA) justice-related services from 2005 to 2018., Results: A four-model class membership solution was identified. Among these classes, risk for suicide was highest among Veterans with greater psychiatric burden, with risk most notable among those with high VA service use. Veterans seeking healthcare primarily focused on substance use disorders or with low psychiatric burden and service use had a lower risk for suicide., Conclusions: Psychiatric multimorbidity is salient as it relates to suicide among Veterans accessing VHA justice-related services. Further evaluation of existing VHA services for this population and methods of augmenting and enhancing care for justice-involved Veterans with histories of co-occurring psychiatric conditions may be beneficial in facilitating suicide prevention efforts., (© 2023.

Objective: The Learning Health Systems Rehabilitation Research Network (LeaRRn), an NIH-funded rehabilitation research resource center, aims to advance the research capacity of learning health systems (LHSs) within the rehabilitation community. A needs assessment survey was administered to inform development of educational resources., Methods: The online survey included 55 items addressing interest in and knowledge of 33 LHS research core competencies in 7 domains and additional items on respondent characteristics. Recruitment targeting rehabilitation researchers and health system collaborators was conducted by LeaRRn, LeaRRn health system partners, rehabilitation professional organizations, and research university program directors using email, listservs, and social media announcements., Results: Of the 650 people who initiated the survey, 410 respondents constituted the study sample. Respondents indicated interest in LHS research and responded to at least 1 competency item and/or demographic question. Two-thirds of the study sample had doctoral research degrees, and one-third reported research as their profession. The most common clinical disciplines were physical therapy (38%), communication sciences and disorders (22%), and occupational therapy (10%). Across all 55 competency items, 95% of respondents expressed "a lot" or "some" interest in learning more, but only 19% reported "a lot" of knowledge. Respondents reported "a lot" of interest in a range of topics, including selecting outcome measures that are meaningful to patients (78%) and implementing research evidence in health systems (75%). "None" or "some" knowledge was reported most often in Systems Science areas such as understanding the interrelationships between financing, organization, delivery, and rehabilitation outcomes (93%) and assessing the extent to which research activities will improve the equity of health systems (93%)., Conclusion: Results from this large survey of the rehabilitation research community indicate strong interest in LHS research competencies and opportunities to advance skills and training., Impact: Competencies where respondents indicated high interest and limited knowledge can inform development of LHS educational content that is most needed., (© The Author(s) 2023.

Objective: The aims of this study were to identify disability subgroups among patients hospitalized for ischemic stroke and to determine the predictors and distal outcomes for the disability subgroups., Methods: A retrospective, cross-sectional study design was used. Data on patients after ischemic stroke were collected from the electronic health records at 5 hospitals within a single health system. Covariates included social and demographic factors. Disability was characterized according to the Activity Measure for Post-Acute Care assessment. Distal outcomes were physical therapist treatment use, occupational therapist treatment use, and discharge disposition. Latent class analysis was used to identify disability subgroups of patients hospitalized for ischemic stroke., Results: A total of 1549 patients were included in the analyses. Five disability subgroups were identified and labeled as follows: globally impaired (subgroup 1), impaired dynamic balance (subgroup 2), impaired self-care (subgroup 3), impaired mobility (subgroup 4), and independent (subgroup 5). Physical therapist treatment use (χ24 = 113.21 [P < .001]) and occupational therapist treatment use (χ24 = 122.97 [P < .001]) varied significantly across the disability subgroups. The globally impaired group had the highest probability of physical and occupational therapist treatment use. Similarly, discharge disposition varied across the subgroups (for home without services, χ24 = 246.61 [P < .001]; for home with home health care, χ24 = 35.49 [P < .001]; for institutional discharge, χ24 = 237.18 [P < .001]). The independent subgroup had the highest probability of discharge to home without services., Conclusion: Five disability subgroups were identified for patients after ischemic stroke. The disability subgroups provide a common language for clinicians to organize the heterogeneity of disability after stroke., Impact: Using the disability subgroups, the multidisciplinary team might be able to improve the accuracy and efficiency of care decisions. The number of current rehabilitation interventions is indeterminable; these subgroups may help to guide clinicians in selecting the most beneficial interventions for patients based on subgroup membership., (© The Author(s) 2023.

Objective: To examine racial and ethnic differences in suicide and drug and opioid-related overdose deaths among a population-based cohort of military service members who were diagnosed with a mild traumatic brain injury (mTBI) during military service., Design: Retrospective cohort., Setting: Military personnel receiving care within the Military Health System between 1999 and 2019., Participants: In total, 356 514 military members aged 18 to 64 years, who received an mTBI diagnosis as their index TBI between 1999 and 2019, while on active duty or activated., Main Measures: Death by suicide, death by drug overdose, and death by opioid overdose were identified using International Classification of Diseases, Tenth Revision (ICD-10) codes within the National Death Index. Race and ethnicity were captured from the Military Health System Data Repository., Results: Overall crude rates were 38.67 per 100 000 person-years for suicide; 31.01 per 100 000 person-years for drug overdose death; and 20.82 per 100 000 person-years for opioid overdose death. Crude and age-specific rates for military members who self-identified as Other were higher than all other racial/ethnic groups for all 3 mortality outcomes. Adjusting for age, suicide rates for those classified as Other were up to 5 times that of other racial/ethnic groups for suicide, and up to 11 and 3.5 times that of other race/ethnicity groups for drug and opioid overdose death, respectively., Conclusion: Findings extend previous knowledge regarding risk for suicide and deaths by drug overdose among those with mTBI and highlight new important areas for understanding the impact of race and ethnicity on mortality. Methodological limitations regarding classification of race and ethnicity must be addressed to ensure that future research provides a better understanding of racial and ethnic disparities in suicide and drug overdose mortality among military members with TBI., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: To examine the impact of community-level social determinants of health (SDoH) on the onset of occupational therapy (OT) and physical therapy (PT) services among individuals hospitalized for traumatic brain injury (TBI)., Setting: 14 acute care hospitals in the state of Colorado., Participants: We studied 5825 adults with TBI., Design: In a secondary analysis of de-identified electronic health record data, we performed multivariable logistic and linear regressions to calculate odds ratios (ORs) and 95% CIs for the likelihood of receiving services and duration to initiation of services among those who received them., Main Measures: Community-level SDoH, receipt of rehabilitation services, and onset of rehabilitation services., Results: Multivariable logistic and linear regressions revealed that those in top quartiles for community income were associated with duration to OT services, ranging from OR = 0.33 [05% CI, 0.07, 0.60] for quartile 2 to 0.76 [0.44, 1.08] for quartile 4 compared with those with the lowest quartile. Only the top quartile differed significantly for duration to PT services (0.63 [0.28, 0.98]). Relative to those with below the median community percentage of high school degree, those with above the median were associated with duration to PT services only (-0.32 [-0.60, -0.04]). Neither community percentage with bachelor's degree nor rural-urban designation was associated with duration to either therapy service., Conclusion: Further research is needed to determine whether our SDoH variables were too diffuse to capture individual experiences and impacts on care or whether community-level education and income, and rurality, truly do not influence time to therapy for patients hospitalized with TBI. Other, individual-level variables, such as age, comorbidity burden, and TBI severity, demonstrated clear relationships with therapy onset. These findings may help therapists evaluate and standardize equitable access to timely rehabilitation services., Competing Interests: The authors declare no conflicts of interest.

Objective: Bayesian meta-analyses offer several advantages over traditional approaches, including improved accuracy when using a small number of studies and enhanced estimation of heterogeneity. However, psychological trauma research has yet to see widespread adoption of these statistical methods, potentially due to researchers' unfamiliarity with the processes involved. The purpose of this article is to provide a practical tutorial for conducting random-effects Bayesian meta-analyses., Method: Explanations and recommendations are provided for completing the primary steps of a Bayesian meta-analysis, ranging from model specification to interpretation of results. Furthermore, an illustrative example is used to demonstrate the application of each step. In the example, results are synthesized from six studies included in a previously published systematic review (Holliday et al., 2020), with a combined sample size of 21,244,109, examining the association between posttraumatic stress disorder and risk of suicide in veterans and military personnel., Results: The posterior distributions for each model estimate, such as the pooled effect size and the heterogeneity parameter, are discussed and interpreted with regard to the probability of increased suicide risk., Conclusions: Our hope is that this tutorial, along with the provided data and code, facilitate the use of Bayesian meta-analyses in the study of psychological trauma.

Objective: Psychosocial factors, including combat-related distress (e.g., posttraumatic stress disorder [PTSD]), contribute to postconcussive symptoms (PCS) among veterans with mild traumatic brain injury (mTBI). However, research on risk factors for PCS has focused solely on life-threatening combat experiences, neglecting the morally injurious dimension of combat-related trauma and associated implications for treatment. Morally injurious events (MIEs) are associated with PTSD symptoms among veterans, a robust risk factor of PCS. Nonetheless, the interplay between MIEs, PTSD symptoms, and PCS remains poorly understood. We sought to investigate MIEs as an indirect risk factor for PCS among Veterans with mTBI., Method: This cross-sectional study of 145 veterans with mTBI used path analysis to investigate whether PTSD symptoms mediated the relationship between MIEs (transgressions and betrayals) and PCS (mood-behavioral, vestibular-sensory, and cognitive domains) among 145 veterans with mTBI. We used the Moral Injury Event Scale, PTSD Checklist-Civilian Version, and Neurobehavioral Symptom Inventory to measure MIEs, PTSD, and PCS, respectively., Results: Perceived transgressions were indirectly associated with mood-behavioral (β = .21, p = .005), vestibular-sensory (β = .17, p = .005), and cognitive PCS (β = .20, p = .005), as mediated by PTSD. Greater transgressions were associated with more severe PTSD (β = .27, p = .003), and greater PTSD was associated with more severe mood-behavioral (β = .79, p < .001), vestibular-sensory (β = .64, p < .001), and cognitive PCS (β = .73, p < .001). Betrayals were not indirectly associated with PCS., Conclusions: Findings offer preliminary support for responses to MIEs being a modifiable risk factor for PCS among veterans. Interventions designed to foster veterans' recovery by targeting the unique emotions and beliefs associated with MIEs may be indicated. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Objective: Kibler et al. (2009) reported that hypertension was related to PTSD independent of depression. These two conditions have significant diagnostic overlap. The present study sought to conceptually replicate this work with a veteran sample, using Bayesian estimation to directly update past results, as well as examine symptom severity scores in relation to hypertension., Method: This was a secondary analysis of data obtained from the United States-Veteran Microbiome Project. Lifetime diagnoses of PTSD and major depressive disorder (MDD) were obtained from a structured clinical interview and hypertension diagnoses were extracted from electronic medical records. PTSD and depressive symptom severity were obtained from self-report measures. Logistic regressions with Bayesian estimation were used to estimate the associations between hypertension and (a) psychiatric diagnostic history and (b) symptom severity scores., Results: Compared with veterans without lifetime diagnoses of either disorder, the PTSD-only group was estimated to have a 29% increase in hypertension risk, and the PTSD + MDD group was estimated to have a 66% increase in hypertension risk. Additionally, higher levels of PTSD symptom severity were associated with a higher risk of hypertension., Conclusion: PTSD diagnosis and symptom severity are uniquely associated with hypertension, independent of MDD or depressive symptom severity. These results support previous findings that PTSD might be a modifiable risk factor for the prevention and treatment of hypertension. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Introduction: Among women Veterans, firearms are the leading suicide means. This has prompted efforts to elucidate factors associated with women Veterans' firearm ownership. This cross-sectional study examined if deployment experiences were associated with firearm ownership among women Veterans and if safety-related beliefs mediated these associations., Methods: 492 previously deployed post-9/11 women Veterans participated in a national survey that included the Deployment Risk and Resilience Inventory-2, subscales of the Posttraumatic Cognitions Inventory and Posttraumatic Maladaptive Beliefs Scale, and firearm ownership questions. Path analysis was used., Results: Perceived threat during deployment was associated with firearm ownership, irrespective of safety-related beliefs. Indirect effects did not support that safety-related beliefs mediated relations between deployment experiences and firearm ownership. The other deployment experiences (sexual harassment, sexual assault, general harassment, combat experiences) were not indirectly associated with firearm ownership, nor were safety-related beliefs (negative cognitions about the world, threat of harm, beliefs about others' reliability and trustworthiness) directly associated with firearm ownership. In an exploratory serial mediation analysis, perceived threat during deployment mediated the association between combat experiences and firearm ownership. In a sensitivity analysis examining firearm acquisition following military service, results were similar, except the indirect effect of combat experiences upon firearm acquisition through perceived threat was not significant., Conclusion: Post-9/11 women Veterans' firearm acquisition and ownership may relate to specific deployment experiences, such as perceived threat; however, longitudinal studies are needed to fully ascertain this. Efforts to address firearm access among post-9/11 women Veterans may benefit from assessing heightened sense of danger during deployment., Competing Interests: Declaration of competing interest The authors report grant funding from the Department of Veterans Affairs (Monteith, Kinney, Holliday, Miller, Schneider, Hoffmire, Simonetti, Brenner, Forster), Department of Defense (Monteith, Hoffmire, Brenner, Holliday, Forster), National Institutes of Health (Brenner, Hoffmire, Forster), American Psychological Association (Monteith), and State of Colorado (Brenner).

Objective: Understand barriers and facilitators of implementing recommended practices for postconcussive sleep disturbance and headache, as outlined in the Veterans Administration/Department of Defense 2016 Clinical Practice Guideline (CPG) for mild traumatic brain injury (mTBI)., Design: Convergent parallel mixed methods., Setting: Ten national Veterans Health Administration (VHA) facilities., Participants: Twenty VHA stakeholders (14 clinicians; 4 researchers; 2 policymakers), 55% of whom were affiliated with a VHA polytrauma rehabilitation center (N=20)., Interventions: None., Main Outcome Measures: Stakeholders rated the quality of recommendations for sleep disturbance and headache using the Appraisal of Guidelines Research and Evaluation-Recommendations Excellence instrument. A descriptive analysis of item scores was performed to understand the following features of the recommendations: (1) clinical credibility (eg, evidence quality), (2) alignment with stakeholder values, and (3) implementability. We conducted semistructured interviews with stakeholders and used descriptive and interpretive analyses to reveal emergent themes. After analyzing the Appraisal of Guidelines Research and Evaluation-Recommendations Excellence and qualitative interview data, we synthesized the results into coherent conclusions (ie, meta-inferences) by comparing and contrasting respective findings., Results: Stakeholders highlighted that the mTBI CPG includes features that reflect clinical priorities (eg, alignment with veteran preferences), making it an appropriate standard of care and facilitating its implementation. However, stakeholders also identified that the design of the mTBI CPG, along with provider-level (eg, knowledge) and facility-level (eg, resources) factors, may create barriers for implementation. In addition to these potential barriers, stakeholders noted a lack of comprehensive and systematic efforts designed to promote the uptake of these recommendations. Findings also revealed stakeholder recommendations for addressing potential barriers (eg, decision support)., Conclusions: With the recent release of the 2021 mTBI CPG, decision makers are encouraged to incorporate information gathered from previous implementation efforts to promote adherence to updated recommendations. Study findings, including recommended changes suggested by stakeholders, offer information that can be leveraged to design such efforts and promote care quality and associated outcomes for veterans with mTBI., (Published by Elsevier Inc.)

Background: Homeless Veterans are at substantially elevated risk for suicide mortality; however, understanding of drivers of suicide in this population remains limited., Method: Building upon prior work, we conducted a retrospective chart review, comprised of a latent class analysis of 724,752 Veterans with use of Veterans Health Administration (VHA) homeless services 2005-2018., Results: A five-model class membership solution was identified. Among these classes, risk for suicide mortality was greatest among Veterans with the highest psychiatric burden and high VHA service use. Those experiencing moderate psychiatric burden or primarily experiencing substance use disorders also experienced elevated risk for suicide mortality relative to those with low burden and service use., Limitations: Models were specific to Veterans accessing VHA homeless services and may not generalize to those not using such services outside VHA care., Conclusions: Continued research and programing remain necessary to determine how to address mental health conditions and engage homeless Veterans in services to facilitate suicide prevention., (Published by Elsevier B.V.)

Background: Sleep problems are common among Veterans with mild traumatic brain injury (mTBI) and may contribute to participation restrictions. However, explanatory mechanisms underlying this relationship are poorly understood. Sleep problems are associated with post-concussive symptoms (e.g., headaches). In turn, post-concussive symptoms contribute to participation restrictions. We hypothesized that post-concussive symptom severity mediates the purported relationship between sleep problems and participation restrictions among Veterans with mTBI., Materials and Methods: This study was a retrospective analysis of clinical data among 8,733 Veterans with mTBI receiving Veterans Health Administration outpatient care. Sleep problems (yes/no) were identified using the sleep-related item from the Neurobehavioral Symptom Inventory (NSI). Post-concussive symptoms were measured using remaining NSI items. Participation restrictions were measured using the Mayo-Portland Adaptability Inventory Participation Index. We specified a latent variable path model to estimate relationships between: (1) sleep problems and three latent indicators of post-concussive symptoms [vestibular-sensory (e.g., headache)]; mood-behavioral [e.g., anxiety]; cognitive [e.g., forgetfulness]); and, (2) the three latent indicators of post-concussive symptoms and two latent indicators of participation restrictions (social and community participation [e.g., leisure activities]; productivity [e.g., financial management]). We examined the indirect effects of sleep problems upon participation restrictions, as mediated by post-concussive symptoms. Estimates were adjusted for sociodemographic factors (e.g., age), injury characteristics (e.g., blast), and co-morbid conditions (e.g., depression)., Results: 87% of Veterans reported sleep problems. Sleep problems were associated with greater social and community participation restrictions, as mediated by mood-behavioral ( β  = 0.41, p  < 0.001) and cognitive symptoms ( β  = 0.13, p  < 0.001). There was no evidence that vestibular-sensory symptoms mediated this relationship ( β  = -0.01, p  = 0.48). Sleep problems were associated with greater productivity restrictions, as mediated by vestibular-sensory ( β  = 0.16, p  < 0.001) and cognitive symptoms ( β  = 0.14, p  < 0.001). There was no evidence that mood-behavioral symptoms mediated this relationship ( β  = 0.02, p  = 0.37)., Discussion: Findings suggest that evidence-based sleep treatment should occupy a prominent role in the rehabilitation of Veterans with mTBI. Indirect effects of sleep problems differed when considering impact on social and community participation vs. productivity, informing individualized rehabilitative care for Veterans with mTBI., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (This work is authored by Adam R.

A retrospective cross-sectional study was conducted on 435 adults with TBI who received occupational therapy services in an acute care trauma center hospital. Outcome measures were (1) occupational therapy utilization based on billed minutes of occupational therapy evaluation and treatment (low vs. high); (2) Activity Measure for Post-Acute Care (AM-PAC) "6-Clicks" to assess activities of daily living level of assistance; and (3) Discharge disposition (community vs. institution). Community discharge included home and supported living facilities. Institutional discharge involved long term care, rehabilitation facility, short term hospital, and skilled nursing facility. Results indicated that change in ADL performance, between admission and discharge, partially mediated the relationship between occupational therapy utilization and community discharge (OR= 0.80, p = .003). High occupational therapy utilization (vs. low) was associated with greater change in ADL performance ( β  = 0.39, p < .001). Greater change in ADL performance was associated with lower odds of community discharge (OR= 0.96, p <.001). Independent of change in ADL performance, higher occupational therapy utilization was associated with significantly lower odds for community discharge (OR = 0.57, p  = 0.023). In conclusion, patients who received more occupational therapy were less likely to be community discharged, as mediated by change in ADL performance. This result can provide direction for future research exploring acute care occupational therapy utilization and discharge disposition.

Objective: To investigate whether a direct measure of need for physical therapy (PT), mobility status, was associated with acute care PT utilization and whether this relationship differs across sociodemographic factors and insurance type., Design: In a secondary analysis of electronic health records data, we estimated logistic regression models to determine whether mobility status was associated with acute care PT utilization. Interactions between mobility and both sociodemographic factors (sex, age, significant other, minority status) and insurance type were included to investigate whether the relationship between mobility and PT utilization varied across patient characteristics., Setting: Five regional hospitals from 1 health system., Participants: A total of 60,459 adults admitted between 2014 and 2018 who received a PT evaluation., Interventions: None., Main Outcome Measures: Received acute care PT; Activity Measure for Post-Acute Care "6-Clicks" measure of mobility., Results: Half of patients who received a PT evaluation received subsequent treatment. Patients with mobility limitations were more likely to receive PT. Interaction terms indicated that among patients with mobility limitations, those who (1) were younger, (2) had significant others, and (3) had private insurance (vs public) were more likely to receive PT. Among patients with greater mobility status, older patients and those without a significant other were more likely to receive PT., Conclusions: The relationship between acute care PT need and utilization differed across sociodemographic factors and insurance type. We offer potential explanations for these findings to guide efforts targeting equitable distribution of beneficial PT services., (Published by Elsevier Inc.)

Objective: Studies of combat emphasize its impact upon health-related outcomes (e.g., depression). Little is known regarding the risk that combat poses to positive outcomes, such as meaning in life, and factors that mitigate this risk. We sought to investigate whether combat poses an indirect risk to life meaning and protective factors that mitigate this risk., Method: Through an online survey at 2 time points, 153 combat-exposed veterans enrolled in college reported combat exposure, health status (posttraumatic stress disorder, depressive, somatic symptoms), meaning in life, and protective factors (social support, instructor autonomy support, coping ability, academic self-efficacy, social and community participation, and meaningful activity). We used path analysis to (a) explore whether baseline health status and life meaning mediated the relationship between combat and follow-up life meaning, and (b) test whether protective factors promoted life meaning despite combat and health status (combat-related risk)., Results: The relationship between combat and follow-up life meaning was mediated by baseline health status and life meaning. Meaningful activity and coping ability were associated with greater life meaning independently of combat-related risk. The indirect effect of combat upon life meaning was weakened when social support, instructor autonomy support, coping ability, and academic self-efficacy were high., Conclusions: Combat is associated with worse health status, in turn limiting student veterans' life meaning. This supports an expanded conception of combat-related risk, in which the effect of combat upon positive outcomes is emphasized. Findings indicate that the proposed protective factors may mitigate combat-related risk. We discuss implications for research and practice.

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. What This Article Adds: Researchers have proposed that occupational therapy practitioners can help prevent veteran suicide by supporting their engagement in meaningful, health-promoting activity and by targeting suicide risk factors within their scope of practice. To the best of our knowledge, this is the first study to offer empirical support for such proposed suicide prevention efforts. Although additional research is needed, these results are promising and highlight a distinct role for occupational therapy in suicide prevention., (Copyright © 2022 by the American Occupational Therapy Association, Inc.)

Importance: Veterans often experience chronic insomnia, and professionals capable of delivering effective interventions to address this problem are lacking., Objective: To evaluate the efficacy of the Restoring Effective Sleep Tranquility (REST) program, an occupational therapist-led cognitive-behavioral therapy for insomnia (CBT-I) intervention to treat sleep problems among post- 9/11 veterans., Design: Wait-list controlled trial with 3-mo follow-up., Setting: Community-based veteran support program in a Mountain West university., Participants: Fifteen post-9/11 veterans with sleep disturbances who were assigned to either the REST intervention or a wait-list control group. Outcomes and Measures: Sleep-related, health-related, and participation-related patient-reported outcomes (PROs) and daily sleep diary variables., Results: Wait-list controlled trial benefits included improved sleep-related (e.g., sleep disturbance), health-related (e.g., depression), and participation-related (e.g., meaningful activity) PROs. Findings were confirmed after participants in both the intervention and the control groups (n = 13) received the REST intervention, including improved daily sleep diary outcomes (e.g., sleep efficiency). All gains were maintained at 3 mo., Conclusions and Relevance: Occupational therapy practitioners with advanced training in CBT-I have the potential to safely deliver an effective CBT-I intervention to veterans with sleep disturbances in a community-based setting. What This Article Adds: Occupational therapy practitioners with sleep-related education and training can positively affect the well-being of their clients through improving sleep participation., (Copyright © 2022 by the American Occupational Therapy Association, Inc.)

In the current policy context, the occupational therapy profession must act to promote and sustain high-value care. Stakeholders have delineated efforts, such as defining and measuring high-quality care processes or promoting the adoption of evidence into practice, that can enhance the value of occupational therapy services. There is a growing recognition, however, that low-value care is the product of deficiencies within health care systems and is therefore most amenable to system-level solutions. To date, the specific nature of system-level changes capable of identifying and rectifying low-value occupational therapy has yet to be elucidated. In this "The Issue Is. . ." column, we introduce occupational therapy to the Learning Health System concept and its essential functions. Moreover, we discuss action steps for occupational therapy stakeholders to lay the foundation for Learning Health Systems in their own professional contexts. What This Article Adds: This article is the first to outline concrete action steps needed to transform occupational therapy practice contexts into Learning Health Systems. Such a transformation would represent a system-level change capable of fostering the delivery of high-value occupational therapy services to clients in a variety of practice settings., (Copyright © 2021 by the American Occupational Therapy Association, Inc.)

Background: Relying solely on null hypothesis significance testing to investigate rehabilitation interventions may result in researchers erroneously concluding the presence of a treatment effect., Objective: We sought to quantify the strength of evidence in favour of rehabilitation treatment effects by calculating Bayes factors (BF 10 s) for significant findings. Additionally, we sought to examine associations between BF 10 s, P-values, and Cohen's d effect sizes., Methods: We searched the Cochrane Database of Systematic Reviews for meta-analyses with "rehabilitation" as a keyword that evaluated a rehabilitation intervention. We extracted means, standard deviations, and sample sizes for treatment and comparison groups from individual findings within 175 meta-analyses. Investigators independently classified the interventions according to the Rehabilitation Treatment Specification System. We calculated t-statistics, P-values, effect sizes, and BF 10 s for each finding. We isolated statistically significant findings (P≤0.05); applied evidential categories to BF 10 s, P-values, and effect sizes; and examined relationships descriptively., Results: We analysed 1935 rehabilitation findings. Across intervention types, 25% of significant findings offered only anecdotal evidence in favour of a treatment effect; only 48% indicated strong evidence. This pattern persisted within intervention types and when conducting robustness analyses. Smaller P-values and larger effect sizes were associated with stronger evidence in favour of a treatment effect. However, a notable portion of findings with P-value 0.01 to 0.05 (63%) or a large effect size (18%) offered anecdotal evidence in favour of an effect., Conclusions: For a substantial portion of statistically significant rehabilitation findings, the data neither support nor refute the presence of a treatment effect. This was the case among a notable portion of large treatment effects and for most findings with P-value>0.01. Rehabilitation evidence would be improved by researchers adopting more conservative levels of significance, complementing the use of null hypothesis significance testing with Bayesian techniques and reporting effect sizes., (Copyright © 2021 Elsevier Masson SAS.

Importance: Hospitalized patients who have difficulty performing activities of daily living (ADLs) benefit from occupational therapy services; however, disparities in access to such services are understudied., Objective: To investigate whether need (i.e., limited ADL performance) predicts acute care occupational therapy utilization and whether this relationship differs across sociodemographic factors and insurance type., Design: A secondary analysis of electronic health records data. Logistic regression models were specified to determine whether ADL performance predicted use of occupational therapy treatment. Interactions were included to investigate whether the relationship between ADL performance and occupational therapy utilization varied across sociodemographic factors (e.g., age) and insurance type., Participants: A total of 56,022 adults admitted to five regional hospitals between 2014 and 2018 who received an occupational therapy evaluation., Intervention: None. Outcomes and Measures: Occupational therapy service utilization, Activity Measure for Post-Acute Care "6-Clicks" measure of daily activity., Results: Forty-four percent of the patients evaluated for occupational therapy received treatment. Patients with lower ADL performance were more likely to receive occupational therapy treatment; however, interaction terms indicated that, among patients with low ADL performance, those who were younger, were White and non-Hispanic, had significant others, and had private insurance (vs. public) were more likely to receive treatment. These differences were smaller among patients with greater ADL performance., Conclusions and Relevance: Greater need was positively associated with receiving occupational therapy services, but this relationship was moderated by age, minoritized status, significant other status, and insurance type. The findings provide direction for exploring determinants of disparities in occupational therapy utilization. What This Article Adds: Acute care occupational therapy utilization is driven partly by patient need, but potential disparities in access to beneficial services may exist across sociodemographic characteristics and insurance type. Identifying potential determinants of disparities in acute care occupational therapy utilization is the first step in developing strategies to reduce barriers for those in need., (Copyright © 2021 by the American Occupational Therapy Association, Inc.)

Importance: Occupational therapy in the neurological critical care unit (NCCU) may enable safe community discharge by restoring functional ability. However, the influence of patient characteristics and NCCU occupational therapy on discharge disposition is largely unknown., Objective: To examine how patient factors and receipt of occupational therapy predict discharge disposition for NCCU patients., Design: Retrospective cross-sectional cohort study of electronic health records data from adults admitted to the NCCU between May 2013 and September 30, 2015., Setting: NCCU in a large urban academic hospital., Participants: Adults age 18 yr or older (N = 1,134) admitted to the NCCU. Outcomes and Measures: Using logistic regression with discharge disposition as the dependent variable, we entered sex, age, length of stay (LOS), baseline Glasgow Coma Scale score, Elixhauser Comorbidity Index, and receipt of occupational therapy services as predictor variables., Results: Of NCCU patients, 39% received occupational therapy. Younger age, shorter LOS, lower comorbidity burden, and not receiving occupational therapy services increased the likelihood of discharge to the community. Men who received occupational therapy were less likely to be discharged to the community than men who did not receive occupational therapy. As age increased, differences in the probability of community discharge decreased between recipients and nonrecipients of occupational therapy services., Conclusions and Relevance: Our results suggest that patients receiving occupational therapy services in the NCCU may have a lower likelihood of community discharge. However, these findings may result from therapist's consideration of the safest discharge location to ensure the greatest balance between independence and support. What This Article Adds: This study's findings suggest that receipt of occupational therapy in the NCCU is associated with higher likelihood for noncommunity discharge (i.e., to inpatient rehabilitation, skilled nursing, or long-term care). However, activity limitations and comorbidity burden may be greater for recipients of occupational therapy, and these NCCU patients are presumably less prepared for community discharge., (Copyright © 2021 by the American Occupational Therapy Association, Inc.)

Objective: Estimate the probability of met and unmet post-acute rehabilitative needs among pediatric patients with moderate to severe traumatic brain injury (TBI)., Participants: One hundred and thirty children who received acute and post-acute rehabilitative services at a hospital for children., Methods: Prospective, observational study. Recommended service needs (1. Medical, 2. Psychological, 3. Cognitive/Educational, 4. Medically Based Therapies, 5. Community/Caregiver/Family Support) were collected at discharge and 1, 6, 12, and 18 months post-injury. Probabilities were estimated using nonlinear logistic regression models. The impact of age at discharge was also assessed., Results: Over time, the estimated probability of need for Medical, Medically Based Therapies, and Cognitive/Educational services were consistently high. Whereas unmet need for Medical and Medically Based Therapies were low, unmet need for Cognitive/Educational services were relatively high. Need for Psychological and Community/Caregiver/Family Support services increased in the months post-discharge, as did the probability of unmet need. Older age at discharge was associated with need for Psychological and Community/Caregiver Family Support services., Conclusions: Findings support the long-term monitoring of need for Psychological and Community/Caregiver/Family Support services among children with moderate to severe TBI. Future research to explore the etiology of unmet needs is warranted.

Background: Relying solely on null hypothesis significance testing (NHST) to investigate rehabilitation interventions may result in researchers erroneously concluding the absence of a treatment effect., Objective: We aimed to distinguish between truly null treatment effects and data that are insensitive to detecting treatment effects by calculating Bayes factors (BF 01 s) for non-significant findings in the rehabilitation literature. Additionally, to examine associations between BF 01 , sample size, and observed P-values., Method: We searched the Cochrane Database of Systematic Reviews for meta-analyses with "rehabilitation" as a keyword that clearly evaluated a rehabilitation intervention. We extracted means, standard deviations, and sample sizes for treatment and comparison groups for individual findings within 175 meta-analyses. Two independent investigators classified the interventions into 4 categories using the Rehabilitation Treatment Specification System. We calculated t-statistics and associated P-values for each finding in order to extract non-significant results (P>0.05). We calculated BF 01 s for 5790 non-significant results and classified BF 01 s based on the strength of evidence in favour of the null hypothesis (i.e., anecdotal, moderate, and strong) across and within intervention types. We examined correlations between BF 01 , sample size, and P-values across and within intervention types., Results: Across all intervention types, most (71.9%) findings were deemed anecdotal, and this pattern remained within distinct intervention types (58.4-76.0%). Larger sample sizes tended to be associated with greater strength in favour of the null hypothesis, both across and within intervention types. Larger P-values were not associated with greater strength in favour of the null hypothesis; this finding was present both across and within intervention types., Conclusion: Our findings indicate that most non-significant rehabilitation findings are unable to distinguish between the true absence of a treatment effect and data that are merely insensitive to detecting a treatment effect. Findings also suggest that rehabilitation researchers may improve the strength of their statistical conclusions by increasing sample size and that Bayes factors may offer unique benefits relative to P-values., (Copyright © 2020.

Objective: To investigate whether indicators of patient need (comorbidity burden, fall risk) predict acute care rehabilitation utilization, and whether this relation varies across patient characteristics (ie, demographic characteristics, insurance type)., Design: Secondary analysis of electronic health records data., Setting: Five acute care hospitals., Participants: Adults (N=110,209) admitted to 5 regional hospitals between 2014 and 2018., Interventions: Not applicable., Main Outcome Measures: Occupational therapy (OT) and physical therapy (PT) utilization. Logistic regression models determined whether indicators of patient need predicted OT and PT utilization. Interactions between indicators of need and both demographic factors (eg, minority status, presence of significant other) and insurance type were included to investigate whether the relation between patient need and therapy access varied across patient characteristics., Results: Greater comorbidity burden was associated with a higher likelihood of receiving OT and PT. Relative to those with low fall risk, those with moderate and high fall risk were more likely to receive OT and PT. The relation between fall risk and therapy utilization differed across patient characteristics. Among patients with higher levels of fall risk, those with a significant other were less likely to receive OT and PT; significant other status did not explain therapy utilization among patients with low fall risk. Among those with high fall risk, patients with VA insurance and minority patients were more likely to receive PT than those with private insurance and nonminority patients, respectively. Insurance type and minority status did not appear to explain PT utilization among those with lower fall risk., Conclusions: Patients with greater comorbidity burden and fall risk were more likely to receive acute care rehabilitation. However, the relation between fall risk and utilization was moderated by insurance type, having a significant other, and race/ethnicity. Understanding the implications of these utilization patterns requires further research., (Published by Elsevier Inc.)

Objective: To understand whether symptoms of health conditions explain the negative association between combat exposure and student Veterans' achievement of a meaningful life. Participants: 153 combat Veterans enrolled in college between November 2013 and April 2018. Methods: Through an online survey, participants reported combat exposure, health status (symptoms of conditions such as depression), and aspects of a meaningful life (belonging, self-understanding, and doing) at two time points. Path analysis was used to explore whether baseline health status mediated the relationship between combat exposure and belonging, self-understanding, and doing at follow-up. Results: Indirect effects indicated that the negative influence of combat on student Veterans' sense of belonging, self-understanding, and doing at follow-up was mediated by poor health at baseline. Conclusions: Combat exposure may contribute to the development of health conditions, which in turn limit student Veterans' experience of three aspects of a meaningful life: a sense of belonging, self-understanding, and doing.

Objective: First, to establish empirically-based effect size interpretation guidelines for rehabilitation treatment effects. Second, to evaluate statistical power in rehabilitation research., Data Sources: The Cochrane Database of Systematic Reviews was searched through June 2019., Study Selection: Meta-analyses included in the Cochrane Database of Systematic Reviews with "rehabilitation" as a keyword and clearly evaluated a rehabilitation intervention., Data Extraction: We extracted Cohen's d effect sizes and associated sample sizes for treatment and comparison groups. Two independent investigators classified the interventions into 4 categories using the Rehabilitation Treatment Specification System. The 25th, 50th, and 75th percentile values within the effect size distribution were used to establish interpretation guidelines for small, medium, and large effects, respectively. A priori power analyses established sample sizes needed to detect the empirically-based values for small, medium, and large effects. Post-hoc power analyses using median sample sizes revealed whether the "typical" rehabilitation study was sufficiently powered to detect the empirically-based values. Post hoc power analyses established the statistical power of each test based on the sample size and reported effect size., Data Synthesis: We analyzed 3381 effect sizes extracted from 99 meta-analyses. Interpretation guidelines for small effects ranged from 0.08 to 0.15; medium effects ranged from 0.19 to 0.36; and large effects ranged from 0.41 to 0.67. We present sample sizes needed to detect these values based on a priori power analyses. Post hoc power analyses revealed that a "typical" rehabilitation study lacks sufficient power to detect the empirically-based values. Post hoc power analyses using reported sample sizes and effects indicated the studies were underpowered, with median power ranging from 0.14 to 0.23., Conclusions: This study presented novel and empirically-based interpretation guidelines for small, medium, and large rehabilitation treatment effects. The observed effect size distributions differed across intervention categories, indicating that researchers should use category-specific guidelines. Furthermore, many published rehabilitation studies are underpowered., (Published by Elsevier Inc.)

Importance: Occupational therapy practitioners can use therapeutic activity to promote veterans' well-being, but the mechanisms through which participation promotes well-being are poorly understood., Objective: To examine whether coping ability, meaningful activity, and social support mediate the relationship between participation and two indicators of veterans' overall well-being: life meaning (psychological well-being) and life satisfaction (subjective well-being)., Design: Explanatory cross-sectional design. We used two multiple mediation models to test whether coping ability, meaningful activity, and social support explained the relationship between participation and both life meaning and life satisfaction. Models were adjusted for demographic characteristics and service-related health conditions (e.g., posttraumatic stress disorder)., Setting: Community., Participants: Three hundred eighty-nine community-based veterans attending college., Intervention: None., Outcomes and Measures: Measures of participation, coping ability, meaningful activity, social support, life meaning, life satisfaction, and service-related health conditions., Results: Meaningfulness of activity partially explained the relationship between participation and both psychological well-being (B = 0.16, standard error [SE] = 0.04, 99% confidence interval [CI] [0.07, 0.27]) and subjective well-being (B = 0.14, SE = 0.03, 99% CI [0.07, 0.24]). Social support partially explained the relationship between participation and subjective well-being (B = 0.05, SE = 0.02, 99% CI [0.01, 0.11]). These findings persisted when symptoms of service-related health conditions were accounted for., Conclusions and Relevance: Veterans' participation is associated with a greater sense of meaningful activity and social support, which in turn promotes psychological and subjective well-being. Occupational therapy practitioners may promote veterans' well-being by supporting engagement in activities that elicit meaning and enable social interaction, although further study is needed., What This Article Adds: This is among the first studies to test mechanisms underlying the relationship between veterans' engagement in activities and their overall well-being. Results may inform treatment theories for activity-based interventions in the veteran population. For example, results indicate that occupational therapy interventions that facilitate engagement in meaningful and shared activities could be developed to promote veterans' well-being., (Copyright © 2020 by the American Occupational Therapy Association, Inc.)

Objective: The purpose of this study was to identify specific and modifiable supported education (SEd) service needs for the veteran population. To do so, we compared veterans participating in SEd services to other veterans on campus with respect to service-related challenges, community reintegration, and academic-related challenges. Identifying independent factors that distinguish veterans receiving SEd services from other veterans on campus may help operationalize interventions that target the unique challenges in this vulnerable population., Method: This study used an exploratory cross-sectional design. We used logistic regression on 410 veterans attending college. Models tested whether sociodemographic characteristics (e.g., age), service-related challenges (e.g., combat exposure), academic-related challenges (e.g., academic self-efficacy), and aspects of community reintegration (e.g., employment status) distinguished veterans receiving SEd services ( n = 94) from veterans on campus ( n = 316)., Results: Veterans who reported (a) more severe combat exposure, (b) more severe posttraumatic stress disorder (PTSD) symptoms, (c) service-related mild traumatic brain injury (mTBI), (d) lower levels of academic self-efficacy, and (e) no paid employment were more likely to participate in SEd services., Conclusions and Implications for Practice: This study established several factors that distinguished veterans receiving SEd services from veterans on campus. Findings indicate that SEd education services for veterans should: (a) apply principles of trauma-informed care, (b) mitigate the influence of PTSD and/or mTBI upon academic success and community reintegration, (c) promote academic self-efficacy, and (d) integrate principles of supported employment.

Importance: Occupational therapists can foster student veterans' resilience, but targets for intervention must be developed., Objective: To explain factors influencing student veterans' successful adaptation to past combat exposure, we hypothesized that participants with high life meaning would have greater levels of protective factors and lower levels of health conditions than those with low life meaning., Design: Longitudinal panel study with two measurements. Participants were classified by level of combat exposure (high-low) and life meaning (high-low) at follow-up, yielding four possible classifications (e.g., resilient group: high combat exposure, high life meaning). Linear mixed models were fit to obtain adjusted means of protective factors and health conditions for each classification; independent-samples t tests were used to examine differences between classifications., Setting: Community., Participants: Convenience sample of 153 combat-exposed student veterans., Outcomes and Measures: Psychometrically sound measures of combat exposure, life meaning, protective factors (social and instructor autonomy support, coping ability, academic self-efficacy, social-community participation, and meaningful activity), and health conditions (posttraumatic stress [PTSD], depression, somatic symptoms)., Results: Groups with high life meaning at follow-up in response to both levels of combat exposure reported greater meaningful activity and coping ability and fewer depressive symptoms. Participants with high life meaning in response to low combat exposure had greater social support and fewer somatic symptoms; participants with high life meaning in response to high combat exposure had lower PTSD., Conclusions and Relevance: Occupational therapists may foster student veterans' resilience by promoting meaningful activity, social support, and coping ability while managing symptoms of health conditions., What This Article Adds: To the best of our knowledge, this study is the first to offer empirical support for potential targets of occupational therapy intervention that address student veterans' successful adaptation to combat exposure. Findings suggest that researchers should develop and test interventions that facilitate successful engagement in meaningful and shared activities and that occupational therapists should work within multidisciplinary teams to bolster coping ability and manage symptoms of combat-related health conditions., (Copyright © 2020 by the American Occupational Therapy Association, Inc.)

Aim: Evidence of factors explaining sports-related concussion (SRC) risk and recovery among high school athletes remains inconclusive., Materials & Methods: Prospective study of a real-world sample of high school athletes (n = 77) who sustained ≤1 SRC. Among those with multiple SRCs, recovery time between events was investigated. To investigate concussion risk, baseline characteristics of athletes with a single versus multiple SRC(s) were compared., Results: Recovery time did not differ across events. There were no differences between those with a single versus multiple SRCs., Conclusion: Recovery time between initial and subsequent concussive events did not differ, suggesting that prior concussion may not prolong recovery. Baseline characteristics did not explain heightened concussion risk. Investigation of these relationships using more representative samples is needed., Competing Interests: Financial & competing interests disclosure LA Brenner consults for professional sports leagues.

Student service members/veterans (SSM/Vs) may experience diminished social support and meaningful activity due to health-related sequelae, in turn threatening their community reintegration. Social and community participation may foster both social support and meaningful activity. This study assessed whether social and community participation explained social support and meaningful activity and evaluated the psychometric properties of the Veterans' Social and Community Participation Assessment (VSCPA). Online surveys generated responses to the VSCPA, indicators of social support, meaningful activity, health-related challenges, and demographic characteristics. Multiple regression models explored predictors of social support and meaningful activity. The VSCPA comprised three components: active community participation, familial and household participation, and social participation. These components exhibited positive associations with social support and meaningful activity and negative relationships with health-related sequelae. Targeting social and community participation among SSM/Vs may be a fruitful means by which occupational therapists bolster social support and meaningful activity.
