Topic: Risk, prevention and care in population studies

Importance There are limited data on which factors affect the critical and complex decision to withdraw life-supporting treatment (LST) in patients with severe traumatic brain injury (sTBI). Objective To determine demographic and clinical factors associated with the decision to withdraw LST in patients with sTBI. Design, setting, and participants This retrospective analysis of inpatient data from more than 825 trauma centers across the US in the American College of Surgeons Trauma Quality Improvement Program database from January 2013 to December 2015 included adult patients with sTBI and documentation of a decision regarding withdrawal of LST (WLST). Data analysis was conducted in September 2019. Main outcomes and measures Factors associated with WLST in sTBI. Results A total of 37931 patients (9817 women [25.9%]) were included in the multivariable analysis; 7864 (20.7%) had WLST. Black patients (4806 [13.2%]; odds ratio [OR], 0.66; 95% CI, 0.59-0.72; P Conclusions and relevance Withdrawal of LST is common in sTBI and socioeconomic factors are associated with the decision to withdraw LST. These results highlight the many factors that contribute to decision-making in sTBI and demonstrate that in a complex and variable disease process, variation based on race, payment, and region presents as a potential challenge.

Key findings

Why it matters

In this large database study of severe traumatic brain injury, withdrawal of life-supporting treatment was common and was associated with socioeconomic factors including race, payment and region. It concerns decision-making in traumatic brain injury and does not test any treatment, cure or prevention for Alzheimer's disease.
