Race and Insurance Status Disparities in Post-discharge Disposition After Hospitalization for Major Trauma

Abstract

Background: Investigations detailing predictive measures of hospital disposition after traumatic injury are scarce. We aim to examine the discharge practices among trauma centers in the US and to identify factors that may influence post-hospital disposition.

Methods: A retrospective analysis of trauma patients using the American College of Surgeons-Trauma Quality Improvement Program dataset from 2007-2017. Primary study outcome was hospital disposition (including long term care facility [LTC], others). Secondary outcomes included: Intensive Care Unit (ICU)-length of stay (LOS), complications, others).

Results: 6 899 538 patients were analyzed. Odds of LTC discharge was significantly higher for Black patients (aOR = 1.30, 95% CI:1.24-1.37), abbreviated injury score (AIS) ≥3 (aOR = 4.22, 95% CI: 4.05-4.39), and higher injury severity score (ISS) (aOR = 9.41, 95% CI:9.03-9.80). Significantly more self-pay patients were discharged home compared to other insurance types (P < .0001). Significantly longer hospital- and ICU-LOS were experienced by those who had an AIS ≥3 (hospital: 4.8 days (±7.1) vs. 7.9 (±10.1); ICU: 4.6 (±6.9) vs. 5.9 (±7.9), P < .0001) and had a high ISS (hospital: 4.5 days (±5.9) vs. 16.8 (±17.9); ICU: 3.6 (±5.0) vs. 10.2 (±11.5), P < .0001).

Conclusions: Patient race, insurance status, and injury severity were predictive of post-hospitalization care discharge. Self-pay and Black patients were less likely to be discharged to secondary care facilities. These findings have the potential to improve in-hospital patient management and predict discharge secondary care needs, and necessitate the need for future research to investigate the extent of inequalities in access to trauma care.
