ObjectiveTo assess the incidence of, causes for, and factors associated with readmission to an acute care hospital (RTAC) during inpatient rehabilitation for traumatic brain injury (TBI).DesignProspective observational cohort.SettingInpatient rehabilitation.ParticipantsIndividuals with TBI admitted consecutively for inpatient rehabilitation (N=2130).InterventionsNot applicable.Main Outcome MeasuresRTAC incidence, RTAC causes, rehabilitation length of stay (RLOS), and rehabilitation discharge location.ResultsA total of 183 participants (9%) experienced RTAC for a total of 210 episodes. Of 183 participants, 161 patients experienced 1 RTAC episode, 17 had 2, and 5 had 3. The mean time from rehabilitation admission to first RTAC was 22±22 days. The mean duration in acute care during RTAC was 7±8 days. Eighty-four participants (46%) had ≥1 RTAC episodes for medical reasons, 102 (56%) had ≥1 RTAC episodes for surgical reasons, and 6 (3%) participants had RTAC episodes for unknown reasons. Most common surgical RTAC reasons were neurosurgical (65%), pulmonary (9%), infection (5%), and orthopedic (5%); most common medical reasons were infection (26%), neurological (23%), and cardiac (12%). Any RTAC was predicted as more likely for patients with older age, history of coronary artery disease, history of congestive heart failure, acute care diagnosis of depression, craniotomy or craniectomy during acute care, and presence of dysphagia at rehabilitation admission. RTAC was less likely for patients with higher admission FIM motor scores and education less than high school diploma. RTAC occurrence during rehabilitation was significantly associated with longer RLOS and smaller likelihood of discharge home.ConclusionsApproximately 9% of patients with TBI experienced RTAC episodes during inpatient rehabilitation for various medical and surgical reasons. This information may help inform interventions aimed at reducing interruptions in rehabilitation for RTAC. RTACs were associated with longer RLOS and discharge to an institutional setting.Copyright © 2015 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.
