Brief Summary
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 combining global data on clinical outcomes with information on hospital resources and patient finances, this study hopes to provide valuable insights into how to improve emergency surgical care across diverse settings, making recommendations that can lead to better access to safe, timely, and affordable treatment for appendicitis worldwide.

Study Arms (1)
Appendicectomy for suspected or confirmed appendicitis
All patients undergoing appendicectomy for suspected or confirmed appendicitis by any surgical approach should be included. This includes patients who went theatre with suspect appendicitis even if the intraoperative or pathology results found a different diagnosis, so long as an appendicectomy was performed. It also includes patients who went to theatre for reasons other than suspected appendicitis but were found to have appendicitis intraoperatively and underwent appendicectomy. This includes interval appendicectomy and right hemicolectomy if performed for acute appendicitis. There are no age restrictions, although, if appropriate participating hospitals can choose to only include children or only adults, based on an age cut-off of their choice.
Interventions
Both open and minimally invasive (laparoscopic and robotic) interventions are eligible for inclusion. Laparoscopic and robotic converted to open cases are also eligible.
Eligibility Criteria
All consecutive patients undergoing appendicectomy for suspected or confirmed appendicitis are eligible for inclusion and should be captured in the study.
You may qualify if:
- Age: There are no age restrictions, although, if appropriate participating hospitals can choose to only include children or only adults, based on an age cut-off of their choice.
- Procedure: All patients undergoing appendicectomy for suspected or confirmed appendicitis by any surgical approach should be included. This includes patients who went theatre with suspect appendicitis even if the intraoperative or pathology results found a different diagnosis, so long as an appendicectomy was performed. It also includes patients who went to theatre for reasons other than suspected appendicitis but were found to have appendicitis intraoperatively and underwent appendicectomy. This includes interval appendicectomy and right hemicolectomy if performed for acute appendicitis.
You may not qualify if:
- Indication: Appendicectomy for any indication other than suspected or confirmed appendicitis should be excluded. For example, patients having appendicectomy for known appendiceal neoplasm.
- Approach: Natural orifice surgery and endoscopic treatment for suspected appendicitis are excluded.
- Previous appendicectomy: Patients having surgery for stump appendicitis are excluded.
- Return to theatre: Patients should be entered into study only once. A patient returning to theatre after appendectomy should not be re-entered as a new patient.
