Pressure Injury Data Reconciliation in a Randomized Controlled Trial.

OBJECTIVE: To advance pressure injury (PrI) research in individuals with spinal cord injury (SCI) by describing lessons learned and recommendations for future research, ultimately promoting PrI prevention and more effective wound care. This paper describes the detailed procedures undertaken to collect and reconcile PrI data and summarizes the types of discrepancies identified. DESIGN: Secondary analyses of PrI data collected between 2009 and 2014 in a randomized controlled trial (parent study). SETTING: Participants in the parent study were recruited from a large rehabilitation center in the Los Angeles area that serves primarily individuals with limited resources. PARTICIPANTS: 232 participants with SCI and a history of 1 or more medically serious PrI (MSPrI) in the previous 5 years. INTERVENTIONS: Participants in the parent study were randomized to a 12-month PrI prevention intervention led by an occupational therapist, or to usual care. MAIN OUTCOME MEASURES: Relations among PrI characteristics, data sources (phone interviews, skin checks, paper and electronic medical records [MRs]), and treatment condition, and sensitivity of 6 different data sources in detecting MSPrIs. RESULTS: The majority (62%) of MSPrIs were in the pelvic region. MRs detected 82% of the MSPrIs overall, making it the most sensitive data source, and scheduled skin checks were the second-most sensitive data source, finding 37% of the MSPrIs. CONCLUSIONS: MR review is the preferred method for ascertaining MSPrIs in clinical trials of interventions designed to reduce the incidence of these injuries. When multiple sources of information are used, careful reconciliation of reports is necessary to ensure accuracy.

Reporting Guideline for RULER: Rasch Reporting Guideline for Rehabilitation Research: Explanation and Elaboration.

The Rasch Reporting Guideline for Rehabilitation Research (RULER) provides peer-reviewed, evidence-based, transparent, and consistent recommendations for reporting studies that apply Rasch Measurement (RM) Theory in a rehabilitation context. The purpose of the guideline is to ensure that authors, reviewers, and editors have uniform guidance about how to write and evaluate research on rehabilitation outcome assessments. The RULER statement includes an organizing framework and a checklist of 59 recommendations. This companion article supports the RULER statement by providing details about the framework, rationale for the domains and recommendations in the checklist and explaining why these considerations are important for improving consistency and transparency in reporting the results of RM studies. This article is not intended to describe how to conduct RM studies but provides rationale for the essential elements that authors should address in each domain. Consistency and transparency in reporting RM studies will advance rehabilitation research if authors consider these issues when planning their study and include the checklist when they submit their manuscript for peer review. A copy of the checklist can be found at [table 2 in https://doi.org/10.1016/j.apmr.2022.03.013].

Rasch Reporting Guideline for Rehabilitation Research (RULER): the RULER Statement.

The application of Rasch Measurement (RM) Theory to rehabilitation assessments has proliferated in recent years. RM Theory helps design and refine assessments so that items reflect a unidimensional construct in an equal interval metric that distinguishes among persons of different abilities in a manner that is consistent with the underlying trait. Rapid growth of RM in rehabilitation assessment studies has led to inconsistent results reporting. Clear, consistent, transparent reporting of RM Theory results is important for advancing rehabilitation science and practice based on precise measures. Precise measures, in turn, provide researchers, practitioners, patients, and other stakeholders with tools for effective decision making. The goal of this Rasch Reporting Guideline for Rehabilitation Research (RULER: Rasch Reporting Guideline for Rehabilitation Research) is to provide peer-reviewed, evidence-based, transparent, and consistent recommendations for reporting studies that apply RM Theory in a rehabilitation context. The purpose of the guideline is to ensure that authors, reviewers, and editors have uniform expectations about how to write and evaluate research on rehabilitation outcome assessments. A task force of rehabilitation researchers, clinicians, and editors met regularly between November 2018 and August 2020 to identify the need for the guideline, develop an organizing framework, identify content areas, and develop the recommendations. This RULER: Rasch Reporting Guideline for Rehabilitation Research statement includes the organizing framework and a checklist of 59 recommendations. The guideline is supported by an Explanation and Elaboration article that provides more detail about the framework and recommendations in the checklist. A glossary of key terms and a recommended iterations table are provided in supplemental online only materials.

Psychometric Properties of the Coma Near-Coma Scale for Adults in Disordered States of Consciousness: A Rasch Analysis.

OBJECTIVES: To examine the construct validity and measurement precision of the Coma Near-Coma scale (CNC) in measuring neurobehavioral function (NBF) in patients with disorders of consciousness receiving postacute care rehabilitation. DESIGN: Rasch analysis of retrospective data. PARTICIPANTS: Participants (N=48) with disordered consciousness who were admitted to postacute care rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: CNC. RESULTS: Assessment with CNC repeated weekly until the participant was conscious or discharged from the postacute care facility (451 participant records). Rating scale steps were ordered for all items. Eight of the 10 CNC items evaluated in this study fit the measurement model (χ2=5332.58; df=11; P=.17); pain items formed a distinct construct. The ordering of the 8 items from most to least challenging makes clinical sense and compares favorably with other published hierarchies of NBF. Tactile items are more easily responded to. Visual and auditory items requiring higher cognitive processing were more challenging. In the full sample, the CNC achieved good measurement precision, with a person separation reliability of 0.87. CONCLUSIONS: The items of the CNC reflect good construct validity and acceptable interrater reliability. The measurement precision achieved indicates that the CNC may be used to make decisions about groups of individuals but that these items may not be sufficiently precise for individual patient treatment decision-making.

Combining Items From 3 Federally Mandated Assessments Using Rasch Measurement to Reliably Measure Cognition Across Postacute Care Settings.

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.

Psychometric Properties and Sex Differences on the Mayo-Portland Adaptability Inventory Participation Subscale (M2PI) in Veterans With Traumatic Brain Injury.

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.

Association of Therapy Time Per Day With Functional Outcomes and Rate of Recovery in Older Adults After Elective Joint Replacement Surgery.

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.

Cognition and Other Predictors of Functional Disability Among Veterans With Mild Traumatic Brain Injury and Posttraumatic Stress Disorder.

BACKGROUND: Limitations in everyday functioning are frequently reported by veterans with a history of mild traumatic brain injury (mTBI) and/or posttraumatic stress disorder (PTSD). Multiple factors are associated with functional disability among veterans, including depression, poor social support, cognition, and substance use. However, the degree to which these factors, particularly cognitive capacities, contribute to functional limitations remains unclear. METHODS: We evaluated performance on tests of processing speed, executive functioning, attention, and memory as predictors of functioning on the World Health Organization Disability Assessment Scale (WHODAS) 2.0 in 288 veterans. Participants were placed in one of the following groups: PTSD-only, mTBI-only, mTBI + PTSD, and neither PTSD nor mTBI (deployed control group). Cognitive test performances were evaluated as predictors of WHODAS 2.0 functional ratings in regression models that included demographic variables and a range of mood, behavioral health, and postconcussive symptom ratings. RESULTS: Multiple cognitive test performances predicted WHODAS 2.0 scores in the deployed control group, but they generally did not predict functioning in the clinical groups when accounting for demographics, mood, behavioral health, and postconcussive symptoms. CONCLUSIONS: In veterans with mTBI and/or PTSD, cognitive test performances are less associated with everyday functioning than mood and postconcussive symptoms.

Self-reported Participation Restrictions Among Male and Female Veterans With Traumatic Brain Injury in Veterans Health Administration Outpatient Polytrauma Programs.

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.

A Pilot Trial Examining the Merits of Combining Amantadine and Repetitive Transcranial Magnetic Stimulation as an Intervention for Persons With Disordered Consciousness After TBI.

OBJECTIVE: Report pilot findings of neurobehavioral gains and network changes observed in persons with disordered consciousness (DoC) who received repetitive transcranial magnetic stimulation (rTMS) or amantadine (AMA), and then rTMS+AMA. PARTICIPANTS: Four persons with DoC 1 to 15 years after traumatic brain injury (TBI). DESIGN: Alternate treatment-order, within-subject, baseline-controlled trial. MAIN MEASURES: For group and individual neurobehavioral analyses, predetermined thresholds, based on mixed linear-effects models and conditional minimally detectable change, were used to define meaningful neurobehavioral change for the Disorders of Consciousness Scale-25 (DOCS) total and Auditory-Language measures. Resting-state functional connectivity (rsFC) of the default mode and 6 other networks was examined. RESULTS: Meaningful gains in DOCS total measures were observed for 75% of treatment segments and auditory-language gains were observed after rTMS, which doubled when rTMS preceded rTMS+AMA. Neurobehavioral changes were reflected in rsFC for language, salience, and sensorimotor networks. Between networks interactions were modulated, globally, after all treatments. CONCLUSIONS: For persons with DoC 1 to 15 years after TBI, meaningful neurobehavioral gains were observed after provision of rTMS, AMA, and rTMS+AMA. Sequencing and combining of treatments to modulate broad-scale neural activity, via differing mechanisms, merits investigation in a future study powered to determine efficacy of this approach to enabling neurobehavioral recovery.

Health Services Research in Rehabilitation and Disability-The Time is Now.

Policy drives practice, and health services research (HSR) is at the intersection of policy, practice, and patient outcomes. HSR specific to rehabilitation and disability is particularly needed. As rehabilitation researchers and providers, we are uniquely positioned to provide the evidence that guides reforms targeting rehabilitative care. We have the expertise to define the value of rehabilitation in a policy-relevant context. HSR is a powerful tool for providing this evidence. We need to continue building capacity for conducting rigorous, timely rehabilitation-related HSR. Fostering stakeholder engagement in these research efforts will ensure we maintain a patient-centered focus as we address the "Triple Aim" of better care, better health, and better value. In this Special Communication we discuss the role of rehabilitation researchers in HSR. We also provide information on current resources available in our field for conducting HSR and identify gaps for capacity building and future research. Health care reforms are a reality, and through HSR we can give rehabilitation a strong voice during these transformative times.

Exploring the attitudes & practices of shared decision-making for CT scan use in emergency department patients with abdominal pain.

BACKGROUND: Shared decision-making (SDM) has been studied in the emergency department (ED) in relation to hospital admissions but not for CT scan utilization. CT scans are a common imaging modality with high accuracy that emit considerable ionizing radiation. This study has three aims: to measure provider and patient preference for SDM; to evaluate patient involvement in the decision to order a CT scan; and to determine the association between patient involvement and CT utilization. METHODS: In this prospective study, stable ED patients with abdominal pain with CT imaging as a likely diagnostic tool, were screened and consented. The Control Preferences Scale assessed patient and provider baseline decision-making preference. Using the OPTION-5 tool, providers were assessed in each encounter for the extent to which they engaged patients in discussions. The association between the Control Preferences Scale, the OPTION-5 score and ultimate CT utilization was evaluated. RESULTS: Twenty-nine encounters were observed. CT was considered in 70% (n = 20) of encounters and ordered in 55% (n = 16). 62% of patients and 59% of providers reported that they prefer "shared responsibility" when making treatment decisions. In >80% of encounters, provider's showed no or minimal effort when discussing whether to perform a CT scan. Provider or patient preference was not associated with patient involvement. Patient involvement was not associated with CT utilization. CONCLUSIONS: High rates of provider and patient preference to use SDM for treatment plans were reported but providers were rarely observed engaging patients with abdominal pain in the decision to order a CT scan.

Impact of urinary incontinence on medical rehabilitation inpatients.

AIMS: To determine the prevalence of urinary incontinence (UI) and its association with rehabilitation outcomes in patients receiving inpatient medical rehabilitation in the United States. METHODS: A retrospective, cohort study of 425,547 Medicare patients discharged from inpatient rehabilitation facilities (IRFs) in 2005. We examined prevalence of UI at admission and discharge for 5 impairment groups. We examined the impact of demographics, health, and functional status on the primary outcome, change in continence status, and secondary outcomes of discharge location and 6-month mortality. RESULTS: Approximately one-quarter (26.6%) of men were incontinent at admission compared to 22.2% of women. In all diagnostic groups, continence status remains largely unchanged from admission to discharge. Patients who are older, have cognitive difficulties, less functional improvement, and longer lengths of stay (LOS), are more likely to remain incontinent, compared to those who improved, after controlling for patient factors and clinical variables. UI was significantly associated with discharge to another post-acute setting (PAC). For orthopedic patients, UI was associated with a 71% increase in the likelihood of discharge to an institutional setting after controlling for patient factors and clinical variables. UI was not associated with death at 6 months post-discharge. CONCLUSIONS: UI is highly prevalent in IRF patients and is associated with increased likelihood of discharge to institutional care, particularly for orthopedic patients. Greater attention to identifying and treating UI in IRF patients may reduce medical expenditures and improve other outcomes. Neurourol. Urodynam. 36:176-183, 2017. © 2015 Wiley Periodicals, Inc.

Responsiveness, Minimal Detectable Change, and Minimally Clinically Important Differences for the Disorders of Consciousness Scale.

OBJECTIVES: To determine the responsiveness, minimal detectable change (MDC95), and minimally clinically important difference (MCID) of the Disorders of Consciousness Scale (DOCS-25) in patients with severe traumatic brain injury (TBI) and to report the percentages of patients' change scores exceeding MDC and MCID after 3 weeks of inpatient rehabilitation. SETTING: Post-acute rehabilitation hospitals. PARTICIPANTS: One hundred seventy-two patients with severe TBI. Ninety-two were included in the DOCS-25 3-week analysis. DESIGN: Retrospective cohort study. MAIN MEASURE(S): Disorders of Consciousness Scale, Glasgow Coma Scale. RESULTS: The effect size and standardized response mean of the DOCS-25 for those who improved were 0.45 and 1.3, respectively-moderate to large by Cohen criteria. The MDC95 (95% confidence interval) was 5.6. Distribution-based MCIDs for small (0.20 SD), moderate (0.33 SD), and large (0.50 SD) differences were 2.6 units, 4.4 units, and 6.6 units, respectively. The anchor-based MCID was 8.6 units. On average, patients who improved (n = 57) gained 14.5 units by week 3, exceeding the anchor-based MCID. On average, patients who did not improve (n = 35) declined by 7.2 units, which exceeds both the MDC95 and the largest distribution-based MCID. CONCLUSION(S): The DOCS-25 is a responsive, clinician-observed assessment tool for capturing change in neurobehavioral function in adults recovering from severe TBI. This is the first study to provide evidence for the size of neurobehavioral function change that might indicate meaningful recovery in patients with severe TBI. Results from this study may support future research by better informing sample size calculations for clinical trials and also assist clinicians in identifying when variation in level of consciousness is consequential enough to warrant changes in intervention.

Napping and Nighttime Sleep: Findings From an Occupation-Based Intervention.

OBJECTIVE: To describe sleeping behaviors and trends over time among an ethnically diverse group of community-living older adults. METHOD: A descriptive secondary data analysis of a subsample (n = 217) from the Lifestyle Redesign randomized controlled trial was done to explore baseline napping and sleeping patterns as well as 6-mo changes in these outcomes. RESULTS: At baseline, the average time sleeping was 8.2 hr daily (standard deviation = 1.7). Among all participants, 29% reported daytime napping at baseline, of which 36% no longer napped at follow-up. Among participants who stopped napping, those who received an occupation-based intervention (n = 98) replaced napping time with nighttime sleep, and those not receiving an intervention (n = 119) experienced a net loss of total sleep (p < .05). CONCLUSION: Among participants who stopped napping, the occupation-based intervention may be related to enhanced sleep. More research examining the role of occupation-based interventions in improving sleep is warranted.

Implementing trials of complex interventions in community settings: the USC-Rancho Los Amigos pressure ulcer prevention study (PUPS).

BACKGROUND: Randomized trials of complex, non-pharmacologic interventions implemented in home and community settings, such as the University of Southern California (USC)-Rancho Los Amigos National Rehabilitation Center (RLANRC) Pressure Ulcer Prevention Study (PUPS), present unique challenges with respect to (1) participant recruitment and retention, (2) intervention delivery and fidelity, (3) randomization and assessment, and (4) potential inadvertent treatment effects. PURPOSE: We describe the methods employed to address the challenges confronted in implementing PUPS. In this randomized controlled trial, we are assessing the efficacy of a complex, preventive intervention in reducing the incidence of, and costs associated with, the development of medically serious pressure ulcers in people with spinal cord injury. METHODS: Individuals with spinal cord injury recruited from RLANRC were assigned to either a 12-month preventive intervention group or a standard care control group. The primary outcome is the incidence of serious pressure ulcers with secondary endpoints including ulcer-related surgeries, medical treatment costs, and quality of life. These outcomes are assessed at 12 and 24 months after randomization. Additionally, we are studying the mediating mechanisms that account for intervention outcomes. RESULTS: PUPS has been successfully implemented, including recruitment of the target sample size of 170 participants, assurance of the integrity of intervention protocol delivery with an average 90% treatment adherence rate, and enactment of the assessment plan. However, implementation has been replete with challenges. To meet recruitment goals, we instituted a five-pronged approach customized for an underserved, ethnically diverse population. In intervention delivery, we increased staff time to overcome economic and cultural barriers to retention and adherence. To ensure treatment fidelity and replicability, we monitored intervention protocol delivery in accordance with a rigorous plan. Finally, we have overcome unanticipated assessment and design concerns related to (1) determining pressure ulcer incidence/severity, (2) randomization imbalance, and (3) inadvertent potential control group contamination. LIMITATIONS: We have addressed the most daunting challenges encountered in the recruitment, assessment, and intervention phases of PUPS. Some challenges and solutions may not apply to trials conducted in other settings. CONCLUSIONS: Overcoming challenges has required a multifaceted approach incorporating individualization, flexibility, and persistence, as well as the ability to implement needed mid-course corrections.

Psychometric properties of the disorders of consciousness scale.

OBJECTIVE: To provide evidence for psychometric properties of the Disorders of Consciousness Scale (DOCS). DESIGN: Prospective observational cohort. SETTINGS: Seven rehabilitation facilities. PARTICIPANTS: Patients (N=174) with severe brain injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE DOCS RESULTS: Initial analyses suggested eliminating 6 items to maximize psychometrics, resulting in the DOCS-25. The 25 items form a unidimensional hierarchy, rating scale categories are ordered, there are no misfitting items, and differential item functioning was not found according to sex, type of brain injury, veteran status, and days from onset. Person separation reliability (.91) indicates that the DOCS-25 is appropriate for individual patient measurement. Items are well targeted to the sample, with the difference between mean person and item calibrations less than 1 logit. DOCS-25 Rasch measures result in a 62% gain in relative precision over total raw scores. Internal consistency is very good (Cronbach α=.86); interrater agreement is excellent (intracIass correlation coefficient=.90) for both the DOCS-25 and the sensory subscales. The DOCS-25 total measure, but not subscale measures, correlates with the Glasgow Coma Scale and the Coma/Near-Coma Scales and distinguishes significantly between vegetative and minimally conscious states, indicating concurrent validity. CONCLUSIONS: The DOCS-25 is psychometrically strong. It has excellent measurement precision and captures a broad range of patient function, which is critical for capturing recovery of consciousness. The sensory subscales are clinically informative but should not be reported as separate measures. The Keyform synthesizes clinical observations to visualize response patterns with potential for informing clinical decision-making. Future studies should determine sensitivity to change, examine issues of rater severity, and explore the usefulness of the Keyform in clinical practice.

Comparison of discharge functional status after rehabilitation in skilled nursing, home health, and medical rehabilitation settings for patients after hip fracture repair.

OBJECTIVE: To examine differences in rehabilitation outcomes across 3 post-acute care (PAC) rehabilitation settings for patients after hip fracture repair. DESIGN: Prospective, observational cohort study. SETTING: Six skilled nursing facilities (SNFs), 4 inpatient rehabilitation facilities (IRFs), and 8 home health agencies (HHAs) in 10 states. PARTICIPANTS: Patients (N=181) receiving PAC rehabilitation following hip fracture with internal fixation (n=116) or total hip replacement (n=64), or no surgical intervention (n=1). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Self-care and mobility status at PAC discharge measured by the Inpatient Rehabilitation Facility Patient Assessment Instrument. RESULTS: IRF and HHA patients had lower self-care function at discharge relative to SNF patients controlling for patient characteristics, severity, comorbidities, and services. Adding length of stay (LOS) resulted in nonsignificant differences between IRFs and SNFs. In contrast, there was no setting-specific advantage in discharge mobility for patients with or without the addition of LOS. The average LOS of HHA patients was 2 weeks longer than that of SNF patients, whose average LOS was 9 days longer than that of IRF patients (average, 15d). IRF and SNF patients received about the same total minutes of therapy over their PAC stays (∼2100min on average), whereas HHA patients received only approximately 25% as many minutes. CONCLUSIONS: Setting-specific effects varied depending on whether self-care or mobility was the outcome of focus. It remains unclear to what extent rehabilitation intensity or natural recovery effects changes in functional status for patients with hip fracture. This study points to important directions for PAC setting comparative effectiveness studies in the future, including uniform measurement, limited consensus on factors affecting recovery, accounting for selection bias, and using end-point data collection that is at the same follow-up time periods for all settings.

Prescribing multiple neurostimulants during rehabilitation for severe brain injury.

BACKGROUND: Despite a lack of clear evidence, multiple neurostimulants are commonly provided after severe brain injury (BI). The purpose of this study is to determine if the number of neurostimulants received during rehabilitation was associated with recovery of full consciousness or improved neurobehavioral function after severe BI. METHOD: Data from 115 participants were extracted from a neurobehavioral observational study database for this exploratory, retrospective analysis. Univariate optimal data analysis was conducted to determine if the number of neurostimulants influenced classification of four outcomes: recovery of full consciousness during rehabilitation, recovery of full consciousness within one year of injury, and meaningful neurobehavioral improvement during rehabilitation defined as either at least a 4.7 unit (minimal detectable change) or 2.58 unit (minimal clinically important difference) gain on the Disorders of Consciousness Scale-25 (DOCS-25). RESULTS: Number of neurostimulants was not significantly (P > 0.05) associated with recovery of full consciousness during rehabilitation, within one year of injury, or meaningful neurobehavioral improvement using the DOCS-25. CONCLUSIONS: Receiving multiple neurostimulants during rehabilitation may not influence recovery of full consciousness or meaningful neurobehavioral improvement. Given costs associated with additional medication, future research is needed to guide physicians about the merits of prescribing multiple neurostimulants during rehabilitation after severe BI.
