Postoperative Outcomes Within an Enhanced Recovery After Surgery Protocol

Short title POWER Audit Methods 60 days national (Spain) audit of postoperative complications following elective gastrointestinal surgery within an enhanced recovery after surgery (ERAS) protocol. Research sites Hospitals undertaking elective lower gastrointestinal surgery. Objective To provide detailed data describing post-operative complications and associated mortality; and length of stay. To provide detailed data describing adherence to ERAS protocol and its association to morbidity. Number of patients Not specified. All eligible patients undergoing surgery during the study month. Inclusion Criteria All adult patients (aged ≥18 years) undergoing lower gastrointestinal elective surgery within an ERAS protocol during the 60 day study period. Statistical analysis Univariate analysis will be used to test factors (patient, surgical, and ERAS related) associated with surgical complications, length of stay (LOS) and in-hospital death. Single and multi-level logistic regression models will be constructed to identify factors independently associated with these outcomes and to adjust for differences in confounding factors. A stepwise approach will be used to enter new terms. A single final analysis is planned at the end of the study. Summary statistics with post hoc Bonferroni corrections will be used to assess possible dose-response dependence in percentage of patients with postoperative complications and LOS. Proposed Start Date A 60 day period between 2017 Proposed End Date Data collection will end by September 2017 Study Duration Six months
