Morbidity and mortality of Hispanic trauma patients with diabetes mellitus.

PURPOSE: DM and trauma are leading causes of death in Hispanic patients, yet the interaction between them remains obscure. We aimed to assess the complications and in-hospital mortality rate of Hispanic diabetic trauma patients.

METHODS: A retrospective cohort study was carried out using data from the Puerto Rico Trauma Hospital databank. Patients were matched based on gender, age, mechanism of injury, Glasgow Coma Scale, and Injury Severity Score using propensity-score matching. From 2000 to 2014, a total of 1134 patients with DM were compared to 1134 patients who did not have DM. The outcomes measured were hospital and TICU lengths of stay, days on mechanical ventilation, complications, and in-hospital mortality rate. A logistic regression model was carried out to evaluate the relationship of DM with complications and mortality after trauma.

RESULTS: Hispanic patients with DM had longer hospital and TICU stays and required mechanical ventilation for extended periods. Complications, predominantly of an infectious nature, were more common among DM patients than they were among non-DM patients: 31.3% in the DM group vs. 11.6% in the non-DM group (OR 3.46; 95% CI 2.77-4.31). Despite an increase in the number of complications, DM was not associated with higher in-hospital mortality rates.

CONCLUSIONS: DM is associated with a twofold increase in complications in Hispanic diabetic trauma patients, which may account for their longer hospital and TICU stays. This indicates that diabetic Hispanic trauma patients may need earlier and more aggressive intervention to reduce their risk of developing complications.
