Interventions to Reduce Surgical Site Infection in Transmetatarsal Forefoot Amputations: A Feasibility Survey

ABSTRACT

Surgical site infection (SSI) following transmetatarsal amputation (TMA) is common and associated with significant morbidity. However, there is limited evidence to guide perioperative strategies for SSI prevention in this population. A prospective, cross-sectional survey was conducted among vascular specialists. The questionnaire assessed current practice in SSI prevention for TMA, perceptions of evidence gaps, and willingness to participate in future research. Responses were analysed descriptively. Eighty-four valid responses were analysed, with 64.3% from consultant vascular surgeons and 84.5% from UK centres. Most respondents (84.5%) considered SSI after TMA to be a significant issue. The majority preferred primary closure in clean wounds (78.6%) and commonly used short-course antibiotics and interrupted sutures. Over 70% agreed no clear best practice exists, and 65.5% felt high-quality randomised trials are needed. Ninety-three percent expressed willingness to engage in future studies. Equipoise existed regarding interventions including antibiotic duration, wound adjuncts, and closure techniques. Opinion varied regarding whether TMA and major lower limb amputation should be pooled when undertaking research into SSI prevention. Current practice in SSI prevention for TMA is highly variable. This survey demonstrates broad support for rigorous trials to establish effective strategies and highlights the feasibility of future research in this area.
