Care of the older trauma patient following low-energy transfer trauma—highlighting a research void.

Background in high-income countries trauma patients are becoming older, more likely to have comorbidities, and are being injured by low-energy mechanisms. This systematic review investigates the association between higher-level trauma centre care and outcomes of adult patients who were admitted to hospital due to injuries sustained following low-energy trauma. Methods a systematic review was conducted in January 2021. Studies were eligible if they reported outcomes in adults admitted to hospital due to low-energy trauma. In the presence of study heterogeneity, a narrative synthesis was pre-specified. Results three studies were included from 2,898 unique records. The studies' risk of bias was moderate-to-serious. All studies compared outcomes in trauma centres verified by the American College of Surgeons in the USA. The mean/median ages of patients in the studies were 73.4, 74.5 and 80 years. The studies reported divergent results. One demonstrated improved outcomes in level 3 or 4 trauma centres (Observed: Expected Mortality 0.973, 95% CI: 0.971–0.975), one demonstrated improved outcomes in level 1 trauma centres (Adjusted Odds Ratio 0.71, 95% CI: 0.56–0.91), and one demonstrated no difference between level 1 or 2 and level 3 or 4 trauma centre care (adjusted odds ratio 0.91, 95% CI: 0.80–1.04). Conclusions the few relevant studies identified provided discordant evidence for the value of major trauma centre care following low-energy trauma. The main implication of this review is the paucity of high-quality research into the optimum care of patients injured in low-energy trauma. Further studies into triage, interventions and research methodology are required. [ABSTRACT FROM AUTHOR]
