Background: Trauma increases the risk for infection, but it is unknown how infection affects goals-of-care (GOC) decision making. We sought to determine how infections impact transition to comfort measures only (CMO), hypothesizing that infectious complications would expedite withdrawal of life-sustaining treatment (WOLST). Patients and Methods: We performed a retrospective review at a level-one trauma center over two years for adult patients without pre-existing advance directives who were made CMO with length of stay longer than one day. Demographics, injuries, and hospital course including infections and the GOC timeline were collected. Patients were divided on the basis of infection development, defined as an infectious complication requiring antibiotics or more invasive intervention, with subgroup analysis comparing those with single versus multiple infections. The primary end point was time to death or discharge. Results: Two hundred thirty-two patients met inclusion criteria and 72 developed an infection. Pneumonia was the most common infection (53.8%). Although those in the infection group had no substantial difference in demographics or comorbidities, they had higher emergency department Glasgow Coma Scale (GCS; 14 vs. 13), lower rate of head injury (28.6 vs. 49%), and higher time to death or discharge (12 vs. 2 days). Goals-of-care discussions were initiated later based on time to first family meeting (7 vs. 1 days), most occurring after the first infection. Subsequent analysis showed that versus those with a single infection (n = 38), those with multiple infections (n = 34) had a higher time to death or discharge (16.5 vs. 10.5 days) despite no difference in demographics, comorbidities, or trauma severity. Time to first family meeting was longer (8.5 vs. 4.5 days) with most occurring after the first infection. Conclusions: We did not find that development of an infection shortens time to WOLST. The increased time to death or discharge in the setting of multiple infections and similar patient populations may be a marker of provider approach to GOC plus family beliefs. Infectious complications play an uncertain role in end-of-life discussions after trauma.
