P-POSSUM for Outcomes After Abdominal Surgery
Vietnam3,000 participantsStarted 2026-01-01
Plain-language 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.

Inclusion Criteria:
Patients aged 60 years or older. Patients undergoing abdominal surgery at Bach Mai Hospital. Patients managed perioperatively or postoperatively by the Center for Anesthesia and Surgical Intensive Care.
Patients with available perioperative clinical data required to calculate the P-POSSUM score.
Patients with available baseline clinical, comorbidity, or functional status information for frailty assessment.
Patients with available postoperative outcome data for assessment of complications, mortality, or treatment outcomes.
Exclusion Criteria:
Patients younger than 60 years. Patients not undergoing abdominal surgery. Patients undergoing minor procedures without operative severity data required for P-POSSUM calculation.
Patients with missing key physiological or operative variables required to calculate the P-POSSUM score.
Patients with insufficient baseline information for frailty assessment. Patients with insufficient postoperative follow-up data for outcome assessment.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
