[Abstract]
Purpose/Background: Recent studies have shown improved outcomes with the initiation of earlier subcutaneous (SQ) basal insulin. The purpose of this study was to examine the effects of early SQ basal insulin administration on hospital length of stay in patients with mild to moderate diabetic ketoacidosis (DKA). Methods: This was a retrospective, single-center study from a large community teaching hospital that included patients 18 years or older with mild to moderate DKA, identified using ICD-10 codes, who received intravenous (IV) insulin. Patients who received SQ basal insulin prior to a documented anion gap ≤12 mmol/L were considered to have received early SQ basal insulin and were compared to patients who received SQ basal insulin after closure of their anion gap (AG). The primary outcome was hospital length of stay. Secondary outcomes included intensive care unit length of stay, duration of IV insulin, time to anion gap closure, and incidences of rebound hyperglycemia. Safety outcomes included incidences of hypoglycemia, and hypokalemia. Results: Of 301 patients screened, 108 patients were included in the final analysis. Forty patients received early SQ basal insulin and 68 did not. Median hospital length of stay in the nonearly group was 71 h, compared to 62 h in the early group (P = .57). Secondary and safety outcomes were similar between groups. Conclusions: In this study, there was no statistically significant difference in length of stay in patients that received early SQ basal insulin. Larger trials are needed to determine the significance of earlier SQ basal insulin in DKA.
