Appendicitis Global Outcomes (AlliGatOr) Study
An international prospective, multicentre, cohort study that will include consecutive patients undergoing appendicectomy for suspected appendicitis.
The Global Surgery Unit has announced a new trainee-led collaborative cohort study called the Appendicitis Global Outcomes Study (AlliGatOr). This study is delivered by the management team from the NIHR Unit on Global Surgery. This team has successfully delivered the GlobalSurg, COVIDSurg, HIPPO and GECKO studies.
We are looking for collaborators (Hospital leads and Data Collectors) across Aotearoa New Zealand. All collaborators will be PubMed citable co-authors on resulting publications.
AlliGatOr is an international prospective multicentre cohort study which aims to identify areas for whole systems strengthening in emergency care using pre-defined key performance measures. Acute appendicitis is one of the most common surgical emergencies worldwide. Presentation of appendicitis and its management can serve as a benchmark to evaluate the efficiency and effectiveness of emergency health systems.
​
Key Study Features:
- Prospective, observational cohort study, with no changes to patient management
- All hospitals globally performing appendicectomy can participate
- Data collection can occur in any 2-week periods between 3 February and May 2025 for patients age 16 and over
