Can a 100,000-Patient global audit reveal how to make surgery safer?
NCT ID NCT07785076
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This study will track outcomes for 100,000 patients undergoing surgery in 1,000 hospitals across 100 countries. The goal is to understand how post-operative complications vary worldwide and what factors—like hospital resources—might influence them. By comparing results across income levels, researchers hope to identify ways to improve surgical care and reduce preventable deaths.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could identify global patterns in surgical complications and guide improvements in surgical safety, especially in low-resource settings.
- What could go wrong
- This is an observational study, so it cannot prove cause and effect. Data collection across many countries may face inconsistencies, and findings may not apply to every hospital.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Any operation (elective or emergency) performed in an operating theatre is eligible for inclusion, except for minor procedures specified in Appendix A. * All surgical specialties can participate including acute care surgery, breast surgery, cardiac surgery, colorectal surgery, general surgery, gynaecology, hepatobiliary surgery, neurosurgery, obstetrics, oesophagogastric surgery, ophthalmology, oral and maxillofacial surgery, orthopaedics, otolaryngology, paediatric surgery, plastic surgery, thoracic surgery, transplant surgery, trauma surgery, urology and vascular surgery. * Patients undergoing both day case surgery and inpatient surgery should be included. Exclusion Criteria: * Patients who do not undergo an operation (e.g. planned operations that are cancelled). * Patients undergoing angiography or minor procedures. * Procedures performed outside of an operating theatre * Individual participating centres can choose to include children only, adults only, or both children and adults. If including children or adults only, an age cut off should be selected that is appropriate to the local context. * Each individual patient should only be included in the study once, based on the first operation they undergo within the data capture window. Therefore, patients who are re-operated within 30-days should only be entered once.
