Objective To examine associations of patient and injury characteristics, inpatient rehabilitation therapy activities, and neurotropic medications with outcomes at discharge and 9 months post-discharge for patients with traumatic brain injury (TBI) Design Prospective, longitudinal observational study Setting 10 inpatient rehabilitation centers (9 US, 1 Canada) Participants Consecutive patients (n=2130) enrolled between 2008 and 2011, admitted for inpatient rehabilitation after an index TBI injury Interventions Not applicable Main Outcome Measures Rehabilitation length of stay, discharge to home, and Functional Independence Measure (FIM) at discharge and 9 months post-discharge Results The admission FIM Cognitive score was used to create 5 relatively homogeneous subgroups for subsequent analysis of treatment outcomes. Within each subgroup, significant associations were found between outcomes and patient and injury characteristics, time spent in therapy activities, and medications used. Patient and injury characteristics explained on average 35.7% of the variation in discharge outcomes and 22.3% in 9-month outcomes. Adding time spent and level of effort in therapy activities, as well as percent of stay using specific medications, explained approximately 20.0% more variation for discharge outcomes and 12.9% for 9-month outcomes. After patient, injury, and treatment characteristics were used to predict outcomes, center differences added only approximately 1.9% additional variance explained. Conclusions At discharge, greater effort during therapy sessions, time spent in more complex therapy activities, and use of specific medications were associated with better outcomes for patients in all admission FIM Cognitive subgroups. At 9 months post-discharge, similar but less pervasive associations were observed for therapy activities, but not classes of medications. Further research is warranted to examine more specific combinations of therapy activities and medications that are associated with better outcomes.

“…Further testing for nonlinear relationships between age and medication administration (i.e., both very young and very old patients being less likely to be prescribed medications) is also warranted. 21 Anxiolytics, antidepressants, antipsychotics, hypnotics, and antiparkinson agents were less likely to be used with ethnic minorities, particularly those of Asian and Hispanic descent. Given the relatively small number of Asian and Hispanic patients in this sample, further investigation is warranted to evaluate the extent that injury severity and secondary conditions versus unmeasured factors (such as differential cultural preferences or site differences in ethnicity and prescribing preferences) are related to medication use.…”

Objective To describe psychotropic medication administration patterns during inpatient rehabilitation for traumatic brain injury (TBI) and their relationship to patient pre-injury and injury characteristics. Design Prospective observational cohort. Setting multiple acute inpatient rehabilitation units or hospitals. Participants 2,130 individuals with TBI (complicated mild, moderate, or severe) admitted for inpatient rehabilitation. Interventions NA Main Outcome Measure(s) NA Results Most frequently administered was narcotic analgesics (72% of sample) followed by antidepressants (67%), anticonvulsants (47%), antianxiolytics (33%), hypnotics (30%), stimulants (28%), antipsychotics (25%), antiparkinson agents (25%), and miscellaneous psychotropics (18%). The psychotropic agents studied were administered to 95% of the sample with 8.5% receiving only 1 and 31.8% receiving 6 or more. Degree of psychotropic medication administration varied widely between sites. Univariate analyses indicated younger patients were more likely to receive anxiolytics, antidepressants, antiparkinson agents, stimulants, antipsychotics, and narcotic analgesics, while those older were more likely to receive anticonvulsants and miscellaneous psychotropics. Men were more likely to receive antipsychotics. All medication classes were less likely administered to Asians, and more likely to those with more severe functional impairment. Use of anticonvulsants was associated with having seizures at some point during acute care or rehabilitation stays. Narcotic analgesics were more likely for those with history of drug abuse, history of anxiety and depression (premorbid or during acute care), and severe pain during rehabilitation. Psychotropic medication administration increased rather than decreased during the course of inpatient rehabilitation in each of the medication categories except for narcotics. This observation was also true for medication administration within admission functional levels (defined by cognitive Functional Independence Measure (FIM) scores), except for those with higher admission cognitive FIM scores. Conclusion(s) Many psychotropic medications are used during inpatient rehabilitation. In general, lower admission FIM Cognitive groups were administered more of the medications under investigation, compared to those with higher cognitive function at admission. Considerable site variation existed regarding medications administered. The current investigation provides baseline data for future studies of effectiveness.

“…Significant differences in case mix do exist among the sites, 19 and patient characteristics account for approximately 18% of variance when site is not included in a prediction model for hours/week of group therapy. However, once site enters the prediction model, 54% of the variance in group therapy hours/week is explained, suggesting that site-associated factors other than case-mix are driving use of group therapy.…”

Objective To describe the amount and content of group therapies provided during inpatient rehabilitation for traumatic brain injury (TBI), and assess the relationships of group therapy with patient, injury, and treatment factors as well as outcomes. Design Prospective observational cohort. Setting Inpatient rehabilitation. Participants 2,130 consecutive admissions for initial TBI rehabilitation at 10 inpatient rehabilitation facilities (9 in US and 1 Canada) from October 2008 to September 2011. Interventions n/a Main Outcome Measure(s) proportion of sessions that were group therapy (two or more patients were treated simultaneously by one or more clinicians); proportion of patients receiving group therapy; type of activity performed and amount of time spent in group therapy, by discipline; rehabilitation length of stay (RLOS); discharge location; FIM Cognitive and Motor scores at discharge. Results 79% of patients received at least 1 session of group therapy, with group therapy accounting for 13.7% of all therapy sessions and 15.8% of therapy hours. On average, patients spent 2.9 hours per week in group therapy. The greatest proportion of treatment time in group format was in Therapeutic Recreation (25.6%), followed by Speech Therapy (16.2%), Occupational Therapy (10.4%), Psychology (8.1%), and Physical Therapy (7.9%). Group therapy time and type of treatment activities varied among admission FIM cognitive subgroups and treatment sites. Several factors appear to be predictive of receiving group therapy, with treatment site being a major influence. However, group therapy as a whole offered little explanation of differences in the outcomes studied. Conclusion(s) Group therapy is commonly used in TBI rehabilitation, to varying degrees among disciplines, sites, and cognitive impairment subgroups. Various therapeutic activities take place in group therapy, indicating its perceived value in addressing many domains of functioning. Variation in outcomes is not explained well by overall percent of therapy time delivered in groups.
