    Advanced Therapy in Traumatic Brain Injury Inpatient Rehabilitation: Effects on Outcomes During the First Year after Discharge
    (Elsevier, 2019) Timpson, Misti; Hade, Erinn M.; Beaulieu, Cynthia; Horn, Susan D.; Hammond, Flora M.; Peng, Juan; Montgomery, Erin; Giuffrida, Clare; Gilchrist, Kamie; Lash, Aubrey; Dijkers, Marcel; Corrigan, John D.; Bogner, Jennifer; Physical Medicine and Rehabilitation, School of Medicine
    Objective To use causal inference methods to determine if receipt of a greater proportion inpatient rehabilitation treatment focused on higher level functions, e.g. executive functions, ambulating over uneven surfaces (Advanced Therapy, AdvTx) results in better rehabilitation outcomes. Design A cohort study using propensity score methods applied to the TBI-Practice-Based Evidence (TBI-PBE) database, a database consisting of multi-site, prospective, longitudinal observational data. Setting Acute inpatient rehabilitation (IRF). Participants Patients enrolled in the TBI-PBE study (n=1843), aged 14 years or older, who sustained a severe, moderate, or complicated mild TBI, receiving their first IRF admission to one of 9 sites in the US, and consented to follow-up 3 and 9 months post discharge from inpatient rehabilitation. Interventions Not applicable. Main Outcome Measures: Participation Assessment with Recombined Tools-Objective-17, FIMTM Motor and Cognitive scores, Satisfaction with Life Scale, and Patient Health Questionnaire-9. Results Controlling for measured potential confounders, increasing the percentage of AdvTx during inpatient TBI rehabilitation was found to be associated with better community participation, functional independence, life satisfaction, and decreased likelihood of depression during the year following discharge from inpatient rehabilitation. Participants who began rehabilitation with greater disability experienced larger gains on some outcomes than those who began rehabilitation with more intact abilities. Conclusions Increasing the proportion of treatment targeting higher level functions appears to have no detrimental and a small, beneficial effect on outcome. Caution should be exercised when inferring causality given that a large number of potential confounders could not be completely controlled with propensity score methods. Further, the extent to which unmeasured confounders influenced the findings is not known and could be of particular concern due to the potential for the patient’s recovery trajectory to influence therapists’ decisions to provide a greater amount AdvTx.

    Family Involvement in Traumatic Brain Injury Inpatient Rehabilitation: A Propensity Score Analysis of Effects on Outcomes During the First Year After Discharge
    (Elsevier, 2019) Bogner, Jennifer; Peng, Juan; Beaulieu, Cynthia; Horn, Susan D.; Corrigan, John D.; Hammond, Flora M.; Dijkers, Marcel P.; Montgomery, Erin; Gilchrist, Kamie; Giuffrida, Clare; Lash, Aubrey; Timpson, Misti; Physical Medicine and Rehabilitation, School of Medicine
    Objective To evaluate the effect of family attendance at inpatient rehabilitation therapy sessions on traumatic brain injury (TBI) patient outcomes at discharge and up to 9 months postdischarge. Design Propensity score methods are applied to the TBI Practice-Based Evidence database, a database consisting of multisite, prospective, longitudinal, and observational data. Setting Nine inpatient rehabilitation centers in the United States. Participants Patients (N=1835) admitted for first inpatient rehabilitation after an index TBI. Intervention Family attendance during therapy sessions. Main Outcome Measures Participation Assessment for Recombined Tools-Objective-17 (Total scores and subdomain scores of Productivity, Out and About, and Social Relations), Functional Independence Measure, Satisfaction with Life Scale, and Patient Health Questionnaire-9. Results Participants whose families were in attendance for at least 10% of the treatment time were more out and about in their communities at 3 and 9 months postdischarge than participants whose families attended treatment less than 10% of the time. Although findings varied by propensity score method, improved functional independence in the cognitive area at 9 months was also associated with increased family attendance. Conclusions Family involvement during inpatient rehabilitation may improve community participation and cognitive functioning up to 9 months after discharge. Rehabilitation teams should engage patients’ families in the rehabilitation process to maximize outcomes.

    Impact of Level of Effort on the Effects of Compliance with the 3-Hour Rule
    (Elsevier, 2019) Beaulieu, Cynthia L.; Peng, Juan; Hade, Erinn M.; Corrigan, John D.; Seel, Ronald T.; Dijkers, Marcel P.; Hammond, Flora M.; Horn, Susan D.; Timpson, Misti L.; Swan, Melanie; Bogner, Jennifer; Physical Medicine and Rehabilitation, School of Medicine
    Objective To determine if patients’ level of effort (LOE) in therapy sessions during traumatic brain injury (TBI) rehabilitation modifies the effect of compliance with the 3-Hour Rule of the Centers for Medicare & Medicaid Services. Design Propensity score methodology applied to the TBI-Practice-Based Evidence (TBI-PBE) database, consisting of multi-site, prospective, longitudinal observational data. Setting Acute inpatient rehabilitation facilities (IRF). Participants Patients (n=1820) who received their first IRF admission for TBI in the US and were enrolled for 3 and 9 month follow-up. Main Outcome Measures Participation Assessment with Recombined Tools-Objective-17, FIMTM Motor and Cognitive scores, Satisfaction with Life Scale, and Patient Health Questionnaire-9. Results When the full cohort was examined, no strong main effect of compliance with the 3-Hour Rule was identified and LOE did not modify the effect of compliance with the 3-Hour Rule. In contrast, LOE had a strong positive main effect on all outcomes, except depression. When the sample was stratified by level of disability, LOE modified the effect of compliance, particularly on the outcomes of participants with less severe disability. For these patients, providing 3 hours of therapy for 50%+ of therapy days in the context of low effort resulted in poorer performance on select outcome measures at discharge and up to 9 months post discharge compared to patients with <50% of 3-hr therapy days. Conclusions LOE is an active ingredient in inpatient TBI rehabilitation, while compliance with the 3-Hour Rule was not found to have a substantive impact on the outcomes. The results support matching time in therapy during acute TBI rehabilitation to patients’ LOE in order to optimize long-term benefits on outcomes.

    Traumatic Brain Injury-Practice Based Evidence Study: Design and Patients, Centers, Treatments, and Outcomes
    (Elsevier, 2015-08) Horn, Susan D.; Corrigan, John D.; Bogner, Jennifer; Hammond, Flora M.; Steel, Ronald T.; Smout, Randall J.; Barrett, Ryan S.; Dijkers, Marcel P.; Whiteneck, Gale G.; Department of Medicine, IU School of Medicine
    OBJECTIVES: To describe study design, patients, centers, treatments, and outcomes of a traumatic brain injury (TBI) practice-based evidence (PBE) study and to evaluate the generalizability of the findings to the U.S. TBI inpatient rehabilitation population. DESIGN: Prospective, longitudinal, observational study. SETTING: Ten inpatient rehabilitation centers. PARTICIPANTS: Patients (N=2130) enrolled between October 2008 and September 2011 and admitted for inpatient rehabilitation after an index TBI injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Return to acute care during rehabilitation, rehabilitation length of stay, FIM at discharge, residence at discharge, and 9 months postdischarge rehospitalization, FIM, participation, and subjective well-being. RESULTS: The level of admission FIM cognitive score was found to create relatively homogeneous subgroups for the subsequent analysis of best treatment combinations. There were significant differences in patient and injury characteristics, treatments, rehabilitation course, and outcomes by admission FIM cognitive subgroups. TBI-PBE study patients were overall similar to U.S. national TBI inpatient rehabilitation populations. CONCLUSIONS: This TBI-PBE study succeeded in capturing naturally occurring variation in patients and treatments, offering opportunities to study best treatments for specific patient impairments. Subsequent articles in this issue report differences between patients and treatments and associations with outcomes in greater detail.
