P-POSSUM for Outcomes After Abdominal Surgery

Sponsor: Bach Mai Hospital

Summary

Postoperative complications after abdominal surgery can lead to prolonged recovery, intensive care admission, and death. The P-POSSUM score is a commonly used surgical risk prediction tool, but its performance may vary between hospitals and patient populations. Frailty, especially in older patients, may also affect postoperative outcomes and may improve risk prediction when added to existing scoring systems. This ambispective observational cohort study evaluates the prognostic value of the P-POSSUM score, with additional assessment of frailty and routine perioperative clinical data, for predicting postoperative complications and treatment outcomes in adult patients undergoing abdominal surgery at Bach Mai Hospital. The study includes retrospective data from January 2025 and prospective data collection through May 2026. No intervention is assigned by the investigators. All patients receive routine perioperative care according to clinical practice. The study will assess the predictive performance of P-POSSUM for postoperative complications and mortality, and will explore whether adding frailty-related variables improves risk prediction.
