Effects of an acute care brain injury medicine continuity consultation service on health care utilization and rehabilitation outcomes

Introduction Although general physiatry acute‐care consultation services are commonplace and improve length of stay (LOS), the benefits of a subspecialty physiatric continuity consultation service targeting patients with severe brain injury have not been reported. Objectives Our primary objective was to characterize patient care recommendations from a Brain Injury Medicine (BIM) Continuity Consult Service, and to investigate the effects on acute‐care LOS relative to brain injury patients receiving General Physical Medicine & Rehabilitation (PM&R) Consult Services. Our secondary objectives were to examine inpatient rehabilitation (IPR) health care utilization metrics and costs between groups and evaluate clinical improvements during IPR and discharge disposition. Design Retrospective cohort comparison study. Setting Academic medical center with level 1 trauma center. Participants Adults with severe brain injury admitted to a single‐site acute‐care facility and subsequently admitted to a single inpatient brain injury rehabilitation unit over the same time period. Physiatric Care Models BIM Continuity Consult Service versus General PM&R Consult Service. Main Outcome Measures Acute‐care LOS; unplanned discharges to acute‐care. Results Despite no major demographic or clinical group differences, the BIM Consult Service had more patient comorbidities than General PM&R Consult Service (17.5±5.3 versus 16±5.1;P = .04). BIM Consult Service patients spent fewer days in acute care (30±11.8 versus 36±22.8; P = .008), and early BIM consult (≤7 days after admission) was associated with shorter acute‐care LOS (P
