Predictive Score for and Actual Rates of Ventral Incisional Hernia after Abdominal Surgery

Risk of hernia formation based on HERNIAscore points*
Class I (0-3 points) Class II (4-5 points) Class III (6 points)
Development cohort (n=428) 14 (6.8%) 48 (23.2%) 8 (50.0%)
Validation cohort (n=197) 2 (2.0%) 18 (19.6%) 3 (75.0%)
Overall cohort (n=625) 16 (5.2%) 66 (22.1%) 11 (55.0%)

HERNIAscore = 4*Laparotomy + 3* hand-assisted aparoscopy + 1*COPD + 1*BMI>25 kg/m2. Points based on hazard ratios rounded to the nearest integer minus 1.
