Key result
Proposed major abdominal surgery definition identifies patients with ~19-fold higher critical care admission risk.
Why the study?
There is no clear consensus regarding which surgical procedures constitute major abdominal surgery, despite multiple sources alluding to it without qualification.
Does the proposed definition of major abdominal surgery accurately discriminate between MAS and non-MAS procedures based on real-world proxy measures?
Observational (n=16,353)
Yes
Does the proposed definition of major abdominal surgery accurately discriminate between MAS and non-MAS procedures based on real-world proxy measures?
p-value: p=<0.001
A novel definition of major abdominal surgery was successfully validated using real-world data and unsupervised machine learning, demonstrating significant discriminative ability.

May refine perioperative planning; extends MAS definition validation in observational data but requires prospective confirmation.
Courtney et al. (2023) conducted an observational in Abdominal surgery (n=16,353). Major abdominal surgery (MAS) procedures vs. Non-MAS procedures was evaluated on Differences in proxy measures (patient age, procedure duration, hospital stay, critical care admission) between MAS and non-MAS cohorts (p=<0.001). A hypothesized definition of major abdominal surgery successfully discriminated procedures, with MAS patients having a 19 times greater risk of critical care admission compared to non-MAS procedures.
