Toppo AJ, Pagani NR, Moverman MA, et al. - The break-even analysis was designed to evaluate if the use of silver-impregnated occlusive dressings is a cost-effective measure for preventing prosthetic joint infection (PJI) after primary total knee arthroplasty (TKA) and total hip arthroplasty (THA). Baseline infection rates after TKA and THA, researchers ascertained the cost of revision arthroplasty for PJI, and the cost of a silver-impregnated occlusive dressing based on institutional data and the existing literature. They performed a break-even analysis to compute the minimal absolute risk reduction needed for cost-effectiveness. After TKA and THA, the use of silver-impregnated occlusive dressings was found to be a cost-effective measure for infection prophylaxis.
