Background: Mesh reinforcement can reduce hernia recurrence, but mesh selection is poorly understood, particularly in contaminated defects. Acellular dermal matrix has enabled single-stage ventral hernia repair in clean-contaminated wounds but can be associated with higher complications and cost compared with synthetic mesh. This study evaluated the cost-utility of synthetic mesh and acellular dermal matrix for clean-contaminated ventral hernia repairs.
Methods: A systematic review of articles comparing outcomes for synthetic and acellular dermal matrix repairs identified 14 ventral hernia repair-specific health states. Quality-adjusted life years were determined through Web-based visual analog scale survey of 300 nationally representative individuals. Overall expected cost and quality-adjusted life-years for ventral hernia repair were assessed using a Monte Carlo simulation with sensitivity analyses.
Results: Synthetic mesh reinforcement had an expected cost of $15,776 and quality-adjusted life-year value gained of 21.03. Biological mesh had an expected cost of $23,844 and quality-adjusted life-year value gained of 20.94. When referencing a common baseline (do nothing), acellular dermal matrix (incremental cost-effectiveness ratio, 3378 ($/quality-adjusted life years)) and synthetic mesh (incremental cost-effectiveness ratio, 2208 ($/quality-adjusted life years)) were judged cost-effective, although synthetic mesh was more strongly favored. Monte Carlo sensitivity analysis demonstrated that synthetic mesh was the preferred and most cost-effective strategy in 94 percent of simulations, supporting its overall greater cost-utility. Despite varying the willingness-to-pay threshold from $0 to $100,000 per quality-adjusted life-year, synthetic mesh remained the optimal strategy across all thresholds in sensitivity analysis.
Conclusion: This cost-utility analysis suggests that synthetic mesh repair of clean-contaminated hernia defects is more cost-effective than acellular dermal matrix.
