Access to Rehabilitation After Hospitalization for Traumatic Brain Injury: A National Longitudinal Cohort Study in Sweden

Background Rehabilitation is suggested to improve outcomes following traumatic brain injury (TBI), however, the extent of access to rehabilitation among TBI patients remains unclear. Objective To examine the level of access to rehabilitation after TBI, and its association with health and sociodemographic factors. Method We conducted a longitudinal cohort study using Swedish nationwide healthcare and sociodemographic registers. We identified 15880 TBI patients >= 18years hospitalized >= 3days from 2008 to 2012 who were stratified into 3 severity groups; grade I (n=1366; most severe), grade II (n=5228), and grade III (n=9268; least severe). We examined registered contacts with specialized rehabilitation or geriatric care (for patients >= 65years) during the hospital stay, and/or within 1year post-discharge. We performed a generalized linear model analysis to estimate the risk ratio (RR) for receiving specialized rehabilitation or geriatric care after a TBI based on sociodemographic and health factors. Results Among TBI patients, 46/35% (grade I), 14/40% (grade II), and 5/18% (grade III) received specialized rehabilitation or geriatric care, respectively. Being currently employed or studying was positively associated (RR 1.7, 2.3), while living outside of a city area was negatively associated (RR 0.36, 0.79) with receiving specialized rehabilitation or geriatric care. Older age and a prior substance use disorder were negatively associated with receiving specialized rehabilitation (RR 0.51 and 0.81). Conclusion Our results suggest insufficient and unequal access to rehabilitation for TBI patients, highlighting the importance of organizing and standardizing post-TBI rehabilitation to meet the needs of patients, regardless of their age, socioeconomic status, or living area.
