Background: Dedicated emergency general surgery (EGS) service models were developed to improve efficiency of care and patient outcomes. The degree to which the EGS model delivers these benefits is debated. We performed a systematic review of the literature to identify whether the EGS service model is associated with greater efficiency and improved outcomes compared to the traditional model. Methods:We searched MEDLINE, Embase, Scopus and Web of Science (Core Collection) databases from their earliest date of coverage through March 2017. Pri mary outcomes for efficiency of care were surgical response time, time to operation and total length of stay in hospital. The primary outcome for evaluating patient out comes was total complication rate. Results:The EGS service model generally improved efficiency of care and patient outcomes, but the outcome variables reported in the literature varied.Conclusion: Development of standardized metrics and comprehensive EGS data bases would support quality control and performance improvement in EGS systems.
