A Global Prospective Cohort Study on Outcomes of Appendicectomy for Appendicitis

This study aims to assess and improve the global management of appendicitis, the most common emergency surgery, by examining various aspects of emergency care systems worldwide. Appendicitis is a time-sensitive condition, and delays in diagnosis or treatment can lead to complications, affecting patient outcomes and increasing healthcare costs. The study uses appendicitis as a "tracer condition" to explore how different healthcare systems manage emergency care, focusing on factors like access, quality, and efficiency. By gathering data from hospitals worldwide, the study seeks to identify areas where emergency surgical care can be improved, particularly in low- and middle-income countries (LMICs). The main goal is to identify gaps in emergency care systems, using a set of key performance measures (KPMs) that assess access to care, the quality of surgical treatment, and patient safety. These include factors like the time from symptom onset to first surgical assessment, the rate of appendectomy performed via minimally invasive (laparoscopic) surgery, and postoperative complications. The study aims to collect data on at least 14,000 patients from around 500 hospitals globally between February and May 2025. The data will be analyzed by hospital income group (from low to high) to understand how different resource levels impact outcomes and to help guide future policy and practice improvements. The study also includes two sub-studies that focus on specific issues in surgical care. The Sustainability and Waste Management sub-study aims to explore how hospitals manage waste and sustainability practices in operating theatres. This sub-study is part of global efforts to reduce carbon emissions in healthcare settings. The Financing sub-study examines the financial burden of appendicectomy, particularly the out-of-pocket costs for patients in LMICs. It will explore how the costs of open vs. laparoscopic surgery differ and investigate the impact of these costs on patients. By
