Use of Clindamycin for Necrotizing Soft Tissue Infection Decreases Amputation Rate

Objective: To identify the impact of clindamycin use on mortality and amputation rates in patients with necrotizing fasciitis. Design: Retrospective review. Setting: Level 1 trauma center, single-center study. Patients/Participants: All patients from 2008 to 2019 with a diagnosis of necrotizing fasciitis. One hundred ninety patients were included in statistical analysis. Intervention: Use of clindamycin in the initial antibiotic regimen in the treatment of necrotizing soft tissue infection. Main Outcome Measurements: Amputation and mortality rates. Results: Patients who received clindamycin had 2.92 times reduced odds of having an amputation when compared with their counterparts, even when American Society of Anesthesiologist scores, comorbidities, smoking, drug use, alcohol consumption, race, ethnicity, sex, and age were controlled for and regardless of other antibiotics started (P = 0.015). There was no significant difference in mortality rate between those patients who did and did not receive clindamycin as part of their initial antibiotic regimen (8.3% vs. 11.6%, respectively; P = 0.453). Conclusion: The use of clindamycin in the initial antibiotic regimen for treatment of NSTI was shown to significantly decrease rates of amputation but not mortality.
