Inter-Rater Agreement of the Classification of Intraoperative Adverse Events (ClassIntra) in Abdominal Surgery
Authors' conclusion
ClassIntra has an almost perfect inter-rater agreement for the classification of iAEs. An increasing grade of ClassIntra was associated with a higher incidence of postoperative complications.
Study context
- Population
- Elective abdominal surgeries in the LAPAD study
- Participants
- 755 surgeries
- Comparison
- ClassIntra grading by team 1 vs team 2
- Primary endpoint
- Inter-rater agreement of ClassIntra grades (Cohen kappa)
Methodological detailssecondary use of data from the LAPAD study, cohort of elective abdominal surgeries
- Secondary use of data from the LAPAD study
- Cohort of elective abdominal surgeries
Primary result
As reported in the abstract
Cohen kappa coefficient for ClassIntra grades, 95% CI 0.84-0.90
0.87
IAEs rated in 333 of 755 surgeries by team 1
44%
IAEs rated in 324 of 755 surgeries by team 2
43%
Further findings
Postoperative complications (≥1)
- Patients with at least 1 postoperative complication
- 278 (37%)
- Risk of postoperative complications increased with every increase in ClassIntra severity grade
Predictors of postoperative complications
- Intraoperative hypotension, MD
- 23.41 (95% CI 12.93-33.90)
- Other organ injuries, MD
- 18.90 (95% CI −4.22 - 42.02)
- Strongest predictors
