Background For years, surgical emergencies in Ecuador were managed on a case-by-case basis without significant standardization. To address these issues, the Regional Hospital Vicente Corral Moscoso adapted and implemented a model of ''trauma and acute care surgery'' (TACS) to the reality of Cuenca, Ecuador. Methods A cohort study was carried out, comparing patients exposed to the traditional model and patients exposed to the TACS model. Variables assessed included number of surgical patients attended to in the emergency department, number of surgical interventions, number of surgeries performed per surgeon, surgical wait time, length of stay and in-hospital mortality.Results The total number of surgical interventions increased (3919.6-5745.8, p B 0.05); by extension, the total number of surgeries performed per surgeon also increased (5.37-223.68, p B 0.05). We observed a statistically significant decrease in surgical wait time (10.6-3.2 h for emergency general surgery, 6.3-1.6 h for trauma, p B 0.05). Length of stay decreased in trauma patients (9-6 days, p B 0.05). Higher mortality was found in the traditional model (p B 0.05) compared to the TACS model. Conclusions The implementation of TACS model in a resource-restrained hospital in Latin America had a positive impact by decreasing surgical waiting time in trauma and emergency surgery patients and length of stay in trauma patients. We also noted a statistically significant decrease in mortality. Savings to the overall system and patients can be inferred by decreased mortality, length of stay and surgical wait times. To our knowledge, this is the first implementation of a TACS model described in Latin America.
