Leveraging a statewide quality collaborative to understand population-level hernia care.

Background: Although ventral hernia repair (VHR) is extremely common, there is profound variation in operative technique and outcomes. This study describes the results of a statewide registry capturing hernia-specific variables to understand population-level practice patterns.

Methods: Retrospective analysis of adult patients in a new statewide hernia registry undergoing VHR in 2020.

Results: 919 patients underwent VHR across 57 hospitals and 279 surgeons. Hernia width was <2 cm in 233 (25%) patients, 2-5 cm in 420 (46%) patients, 5-10 cm in 171 (19%) patients, and >10 cm in 95 (10%) patients. Mesh was used in 79% of cases and varied in use from 53% of hernias <2 cm to 95% of hernias >10 cm. The most common mesh type was synthetic non-absorbable (46%), followed by synthetic absorbable mesh (37%). The incidence of complications was significantly associated with hernia width.

Conclusions: A population-level, hernia-specific database captured operative details for 919 patients in 1 year. There was significant variation in mesh use and outcomes based on hernia size. These nuanced data may inform higher quality clinical practice.
