Identification of core items in the enhanced recovery pathway

Summary Background & aims The Enhanced Recovery After Surgery (ERAS) pathway represents an optimal approach in patients undergoing colorectal surgery but complexity in implementing its items could limit its application. The aim of this study is to identify possible core items within an ERAS pathway following elective colorectal resection. Methods This is a retrospective review of data prospectively collected between January 2014 and September 2015 by 14 Italian Hospitals in an electronic registry dedicated to an ERAS protocol. 722 patients undergoing elective colorectal surgery within an ERAS protocol have been included in the study. Adherence to ERAS items was assessed in all patients. A secondary analysis was restricted to pre- and intraoperative ERAS items. Time to readiness for discharge (TRD) was the primary endpoint of the study. Postoperative overall morbidity was the secondary endpoint. Results Multivariate analyses showed that active intraoperative warming (p = 0.008), early stop of intravenous fluids (p = 0.0001), and early removal of urinary catheter (p = 0.0001) were associated to a shorter TRD, while early stop of intravenous fluids (p
