Variables Associated with Amputation Among 600 Community-Acquired Hand Infections—A Surgical and Infectiology Cohort

Résumé fourni par la source

Background/Objectives: Posttraumatic infections are common in emergency hand surgery. Amputation is the worst outcome and can occur at admission or during the course of antibiotic treatment and iterative surgical debridement. We wondered if the prolongation of antibiotic treatment beyond the usual indication, and more surgical debridement besides its immediate benefit, could reveal additional preventive effect against amputation during or immediately after therapy. Methods: We investigate 166 risk association (variables) of community-acquired (traumatic) hand infection with overall treatment failure using a specifically designed retrospective single-center cohort between 1 November 2018 and 31 October 2020. Results: Among 600 patients (362 males; 71 (11.8%) with diabetes mellitus), 58 (9.7%) required initially unplanned amputation during the therapeutic ourse. Multivariate Cox regression analysis identified only inherent risks associated with “amputation”: male sex (hazard ratio [HR] 3.12, 95% confidence interval [CI] 1.28–7.69, p = 0.01), age (HR 1.03, 95% CI 1.01–1.04, p = 0.03), diabetes (HR 2.40, 95% CI 1.15–5.01, p = 0.02), whereas no interventional variables such as early flapping or antibiotic-related parameters (early empirical antibiotic use, total duration of antibiotics including its initial parenteral use, and choice of agent) altered outcomes. Conclusions: In severe (traumatic) hand infections among 600 patients, the outcomes were determined by the extent of trauma and underlying comorbidities. The outcomes do not seem to be effectively reduced by more surgery or initial antibiotic treatment.
