Implementation of an emergency abdominal surgery classification: A propensity score-weighted before-after study
Main findingResult — go to the resultRelative risk 0.40 95% CI 0.19–0.85Authors' conclusion
This study shows that the implementation of a classification of emergency abdominal surgery could reduce the rate of postoperative complications probably by reducing the delay to surgery.

Main finding
As reported in the abstract
Relative risk
0.40
95% CI 0.19–0.85
P < 0.001
After vs Before
RR 0.40 (95% CI 0.19–0.85); P < 0.001
Further findings
Excess ideal time to surgery (iTTS) (actual time to surgery (aTTS)/iTTS ratio), postoperative complications (respiratory, infectious, digestive, cardiac) and AKI
- Significantly lower in the post-implementation group
- P < 0.05
