Abstract
- Newer strategies to decolonize the shoulder of Cutibacterium acnes may hold promise in minimizing the occurrence of infections after shoulder arthroplasty, but little is known about their cost-effectiveness. Break-even models can determine the economic viability of interventions in settings with low outcome event rates that would realistically preclude a randomized clinical trial. We used such modeling to determine the economic viability of benzoyl peroxide and hydrogen peroxide for infection prevention in shoulder arthroplasty. Skin decolonization protocol costs ($11.76 for benzoyl peroxide; $0.96 for hydrogen peroxide), baseline infection rates for shoulder arthroplasty (0.70%), and infection-related care costs ($50,230) were derived from institutional records and the literature. A break-even equation incorporating these variables was developed to determine the absolute risk reduction (ARR) in the infection rate to make prophylactic use economically justified. The number needed to treat was calculated from the ARR. Topical benzoyl peroxide is considered economically justified if it prevents at least 1 infection out of 4348 shoulder arthroplasties (ARR = 0.023%). Hydrogen peroxide is economically justified if it prevents at least 1 infection out of 50,000 cases (ARR = 0.002%). These protocols remained economically viable at varying unit costs, initial infection rates, and infection-related care costs. The use of topical benzoyl peroxide and skin preparations with hydrogen peroxide are highly economically justified practices for infection prevention in shoulder arthroplasty. Efforts to determine drawbacks of routine skin decolonization strategies are warranted as they may change the value analysis. [ABSTRACT FROM AUTHOR]
