Correlates of Rehabilitation Length of Stay in Asian Traumatic Brain Injury Inpatients in a Superaged Country: A Retrospective Cohort Study

Background: While Asia contributes 44.3% of traumatic brain injuries (TBI) worldwide, data regarding Asian TBI inpatient rehabilitation length of stay (RLOS) is scarce. A retrospective cohort study was conducted to determine correlates of inpatient RLOS (days) and prolonged RLOS >30 days (PRLOS &...

Description
Summary:Background: While Asia contributes 44.3% of traumatic brain injuries (TBI) worldwide, data regarding Asian TBI inpatient rehabilitation length of stay (RLOS) is scarce. A retrospective cohort study was conducted to determine correlates of inpatient RLOS (days) and prolonged RLOS >30 days (PRLOS > 30). (2) Methods: Data extraction of discharged inpatient records was performed from 2018 to 2024. Dependent variables included RLOS (days) and PRLOS > 30. Independent variables included demographic characteristics, TBI severity (emergency-room Glasgow Coma Scale-GCS), admission/discharge Functional Independence Measure (FIM), intra-rehabilitation complications, post-traumatic amnesia (PTA) duration, and discharge placement. (3) Results: Altogether, 289 data sets were analysed, median (IQR) age, 64 (28) years, 78.9% (228/289) males, and 79.6% (230/289) Chinese. Median (IQR) RLOS was 28 (21) days, with PRLOS >30 at 39.8% (115/289); RLOS of 44 (19.5) days. PRLOS > 30 was significantly associated with PTA duration >28 days (OR 4.01, 95% CI 1.90–8.45, <i>p</i> < 0.001), admission FIM ≤ 40/126 (OR 4.71, 95% CI 2.32–9.59, <i>p</i> < 0.001), delayed neurosurgical complications (OR 4.74, 95% CI 1.28–17.6, <i>p</i> = 0.02) and discharge to non-home destination (OR 2.75. 95% CI 1.12–6.76, <i>p</i> = 0.03). (4) Conclusion: PRLOS >30 was significantly associated with longer PTA > 4 weeks, lower admission FIM score, delayed neurosurgical complications, and discharge to a nursing home.
