Downloaded from 5 Introduction: The ERAS protocol (Enhanced Recovery After Surgery) is a multimodal pathway 6 7 aimed to reduce surgical stress and to allow a rapid post-operative recovery. Application of the ERAS 8 protocol to colorectal cancer surgery has been limited to a minority of hospitals in Italy. To promote 9 10 the systematic adoption of ERAS in the entire regional hospital network in Piemonte an Audit and 11 12 Feedback approach (A&F) has been adopted together with a cluster randomised trial to estimate the 13 14 true impact of the protocol on a large, unselected population: . 15 Methods: A multicenter stepped wedge cluster randomised trial is designed for comparison between 16 17 standard perioperative management and the management according to the ERAS protocol. The 18 For peer review only 19 primary outcome is the length of hospital stay (LOS). Secondary outcomes are: incidence of post- 20 operative complications, time to patients’ recovery, control of pain and patients’ satisfaction. With 21 22 an A&F approach the adherence to the ERAS items is monitored through a dedicated area in the study 23 24 web site. 25 26 The study includes 28 surgical centers, stratified by activity volume and randomly divided into four 27 groups. Each group is randomly assigned to a different activation period of the ERAS protocol. There 28 29 are four activation periods, one every three months. However, the planned calendar and the total 30 31 duration of the study have been extended by three months due to the COVID-19 pandemic. 32 33 The expected sample size of about 2200 patients has a high statistical power (98%) to detect a 34 reduction of LOS of 1 day and to estimate clinically meaningful changes in the other endpoints. 35 36 Ethics and dissemination: The study protocol has been approved by the Ethical Committee of the http://bmjopen.bmj.com/ 37 38 coordinating Center and by all participating centers. Study results will be timely circulated within the 39 hospital network and published in peer-reviewed journals. 40 41 42 43 44 on September 29, 2021 by guest.
