Incidence of Long-term Disability Following Traumatic Brain Injury Hospitalization, United States, 2003

TLDR

The study aims to develop and validate a predictive model for long‑term disability after traumatic brain injury and estimate its national incidence in 2003. A logistic regression model trained on a South Carolina TBI registry was applied to 2003 nationwide inpatient data to estimate long‑term disability incidence. In 2003, about 124,626 of 288,009 hospitalized TBI survivors (≈43%) developed long‑term disability, underscoring a major public health issue that warrants comprehensive rehabilitation services.

Abstract

Objective Develop and validate a predictive model of the incidence of long-term disability following traumatic brain injury (TBI) and obtain national estimates for the United States in 2003. Data/methods A logistic regression model was built, using a population-based sample of persons with TBI from the South Carolina Traumatic Brain Injury Follow-up Registry. The regression coefficients were applied to the 2003 Healthcare Cost and Utilization Project–Nationwide Inpatient Sample data to estimate the incidence of long-term disability following traumatic brain injury hospitalization. Results Among 288,009 (95% CI, 287,974–288,043) hospitalized TBI survivors in the United States in 2003, an estimated 124,626 (95% CI, 123,706–125,546) had developed long-term disability. Conclusion TBI-related disability is a significant public health problem in the United States. The substantial incidence suggests the need for comprehensive rehabilitative care and services to maximize the potential of persons with TBI.
