Short-term versus long-term trauma mortality: A systematic review.

Trauma is the leading cause of death in the United States for persons under 44 years and the fourth leading cause of death in the elderly. Advancements in clinical care and standardization of treatment protocols have reduced 30-day trauma mortality to less than 4%. However, these improvements do not seem to correlate with long-term outcomes. Some reports have shown a greater than 20% mortality rate when looking at long-term outcomes. The aim of this study was to systematically review the incongruence between short- and long-term mortality for trauma patients.For this systematic review, we searched the Cochrane Library, EMBASE, Ovid Medline, Google Scholar, and Web of Science database to obtain relevant English, German, French, and Portuguese articles from 1965 to 2018.Trauma patients have decreased long-term survival when compared to the general population and when compared with age-matched cohorts. Postdischarge trauma mortality is significantly higher (mean, 4.6% at 3-6 months, 15.8% at 2-3 years, 26.3% at 5-25 years) compared with controls (mean, 1.3%, 2.2%, and 15.6%, respectively). Patient comorbidities likely contribute to long-term trauma deaths. Trauma patients discharged to a skilled nursing facility have worse mortality compared with those discharged either to home or a rehabilitation center. In contrast to data available which illustrate that short-term mortality has improved, quality of evidence was not sufficient to determine if any improvements in long-term trauma mortality outcomes have also occurred.The decreased short-term mortality observed in trauma patients does not appear correlated with decreased long-term mortality. The extent to which increased long-term trauma mortality is related to the initial traumatic insult-versus rising population age and comorbidity burden as well as suboptimal discharge location-requires further study.Systematic Review, level IV.
