Age- and sex-specific predictors of inpatient rehabilitation facility discharge destination for adult patients with traumatic brain injury

Objective : To determine age- and sex-specific predictors of discharge destination among patients with traumatic brain injury (TBI) receiving inpatient rehabilitation facility (IRF) care. Design : Secondary analysis of Uniform Data System for Medical Rehabilitation data. Methods : Logistic regression of patients (N = 221,961) age >= 18, TBI diagnosis, admitted to IRF between 2002 and 2018. Outcome : Discharge destination (subacute vs. home/community settings) Results : Approximately 16% were discharged to subacute vs. 84% home. Younger versus older adults had lower odds of subacute discharge [OR = 0.72; 95% CI: 0.69, 0.76]. Younger females had lower odds of subacute discharge (vs. home) than older females [OR = 0.68; 95% CI: 0.63, 0.74]; younger males had lower odds of subacute discharge (vs. home) than older males [OR = 0.74; 95% CI: 0.70, 0.78]. Younger females versus younger males had lower odds of subacute discharge (vs. home) [OR = 0.83; 95% CI: 0.79, 0.87]. Older females versus older males had lower odds of subacute discharge (vs. home) [OR = 0.93; 95% CI: 0.90, 0.97]. Predictors of discharge destination for age- and sex-stratified groups varied. Conclusions : Younger (vs. older) and female (vs. male) patients had lower odds of subacute discharge vs. home.
