RICA (ERAS) Pathway Adherence and Early Discharge Feasibility After Urgent Uncomplicated Appendectomy (APENERAS)

This multicenter, prospective observational study (APENERAS) evaluates adherence to the RICA (ERAS Zaragoza 2022) perioperative care pathway in adults undergoing urgent laparoscopic appendectomy for uncomplicated acute appendicitis. The study aims to describe real-world adherence to the pathway across participating hospitals and to explore its association with patient safety and recovery outcomes. Key outcomes include postoperative complications (including severity), length of hospital stay, and readmissions within 30 days. Patient-reported satisfaction is also assessed using a structured survey. In addition, the study evaluates the feasibility of early discharge/ambulatory management by intention-to-treat, using a standardized checklist of clinical, functional, and social discharge criteria assessed during the first 24 hours after surgery. No changes to usual clinical care are introduced. Data are collected from routine perioperative management and follow-up.
