Variation in mesh placement for ventral hernia repair: an opportunity for process improvement?

BackgroundIncisional hernia repair (IHR) with mesh has been associated with decreased hernia recurrence. We analyzed variation in mesh use for IHR.MethodsA cohort undergoing IHR from 16 Veterans' Administration (VA) Hospitals was identified. Patient-specific variables were obtained from National Surgical Quality Improvement Program (NSQIP) data. Operative variables were obtained from physician-abstracted operative notes. Univariate and multivariable logistic regression analyses were used to model mesh implantation predictors.ResultsA total of 1,123 IHR cases were analyzed; Mesh was implanted in 69.6% (n = 781). Regression models demonstrated repair at a high performing facility was associated with a nearly 4-fold increase in mesh utilization. Other significant predictors include repair of recurrent hernia, chronic steroid use, and multiple fascial defects.ConclusionsThere is variation in the rate of mesh placement for IHR by VA facility, even after accounting for key explanatory variables. Patterns of mesh placement in IHR appear to be based on practice style.
