Abstract Background: Necrotizing soft-tissue infection (NSTI) is a devastating disease associated with high rates of morbidity and mortality. Hyperglycemia is associated with poor wound healing; however, there are no studies evaluating glycemic control outcomes in patients with NSTI. The objective of this study was to examine disease progression and death in patients with NSTI who achieved early glycemic control (EGC) compared with patients that did not. Methods: A retrospective chart review of patients with NSTI was conducted between November 2011 and August 2017. Early glycemic control was defined as a daily average blood glucose concentration ≤150 mg/dL for a minimum of two consecutive days from admission to hospital day three. The primary outcome of this study was a composite of ≤3 debridement procedures by hospital day 14 and survival to discharge. Secondary outcomes were the total number of debridement procedures, amputation, hospital length of stay (LOS), intensive care unit (ICU) LOS, number of hypoglycemic events throughout hospitalization, and discharge disposition. Results: One-hundred five patients were included in the analysis. There were 62% male patients, mean age of 55.3 years, mean weight of 106.9 kg, and 57.1% with diabetes mellitus (DM). The 54 (51.4%) patients with EGC were less likely to have DM (29.6% versus 86.3%; p < 0.001), had a lower median admission glucose concentration (120.5 [97-144] versus 198 [153-295.5] mg/dL; p < 0.001), and had lower median daily glucose values during the first 96 hours after admission (p < 0.001). There was no significant difference in the primary outcome (83.3%% versus 84.3%; p > 0.99) or incidence of hypoglycemia (14.8% versus 23.5%; p = 0.32). Patients with EGC were more likely to return home after discharge (44.4% versus 23.5%; p = 0.039). Conclusion: Overall, there was no difference in composite clinical outcomes between patients with EGC and those without, although more patients who achieved EGC were discharged home. Patients with DM were less likely to achieve EGC.
