Abstract

Purpose: Necrotizing fasciitis (NF) is a rare, but rapidly progressing bacterial infection of the subcutaneous tissues and muscular fascia with high rates of morbidity and mortality. Our study aims to determine if socioeconomic status (SES) is a predictor of outcomes in NF. Methods: A retrospective review was conducted of patients diagnosed with NF at our institution. Demographic information, insurance status, medical and surgical history, vitals, ASA score, blood laboratory values, surgical procedure information, and outcomes prior to patient discharge were collected. Patient zip codes were utilized to obtain median household incomes at the time of the patient’s surgical procedure to determine SES. Patients without complete data in their medical record were excluded. Initial descriptive statistics and logistic regression models were performed. Results: We identified 196 patients (mean age 50.13 ± 13.03 years, 31.6% female) for inclusion. Mortality rate was 15.3% (n = 30) and 33.7% (n = 66) underwent amputation. Mortality rate was not significantly different across income brackets. Lower income brackets had higher rates of amputation than higher income brackets (p < 0.05). A logistic regression models showed the rate of amputation decreases by 29% for every $10,000 increment in median household income and ASA score decreased by 0.15 units for every $10,000 increase in median household income. Conclusions: Amputation rates in cases of NF are significantly higher in lower SES groups than higher SES groups. Patients with perivascular disease in lower SES groups were more likely to experience serious complications of NF than their counterparts in higher SES groups.
