Abstract

|
|
Purpose : Acute care surgery (ACS) has been practiced in several tertiary hospitals in South Korea since the late 2000s. The medical emergency team (MET) has improved the management of patients with clinical deterioration during hospitalization. This study aimed to identify the clinical effectiveness of collaboration between ACS and MET in hospitalized patients.
Methods : This was an observational before-and-after study. Emergency surgical cases of hospitalized patients were included in this study. Patients hospitalized in the Department of Emergency Medicine or Department of Surgery, directly comanaged by ACS were excluded. The primary outcome was in-hospital mortality rate. The secondary outcome was the alarm-to-operation interval, as recorded by a Modified Early Warning Score (MEWS) of >4.
Results : In total, 240 patients were included in the analysis (131 in the pre-ACS group and 109 in the post-ACS group). The in-hospital mortality rates in the pre- and post-ACS groups were 17.6% and 22.9%, respectively (P = 0.300). MEWS of >4 within 72 hours was recorded in 62 cases (31 in each group), and the median alarm-to-operation intervals of each group were 11 hours 16 minutes and 6 hours 41 minutes, respectively (P = 0.040).
Conclusion : Implementation of the ACS system resulted in faster surgical intervention in hospitalized patients, the need for which was detected early by the MET. The in-hospital mortality rates before and after ACS implementation were not significantly different.
