ADDRESSING PITFALLS IN MANAGEMENT OF DIABETIC KETOACIDOSIS (DKA) WITH A STANDARDIZED PROTOCOL.

Objective: To determine the efficacy and safety of a diabetic ketoacidosis (DKA)-Power Plan (PP) for guiding intravenous (IV) insulin infusions prior to anion gap (AG) closure and administering subcutaneous (SC) insulin >= 1 hour before discontinuing IV insulin. Methods: Retrospective chart review of patients with DKA before (pre-PP) (n = 60) and following (post-PP) (n = 60) implementation of a DKA-PP. Groups were compared for percentage of patients for whom IV insulin therapy was continued until AG closure, the percentage of patients receiving SC insulin >= 1 hour before discontinuation of IV insulin, and percentage of patients with rebound DKA during the index hospitalization. Results: Admission plasma glucose (514 mg/dL vs. 500 mg/dL; P = .36) and venous pH (7.2 vs. 7.2; P = .57) were similar in pre- and post-PP groups. Inappropriate discontinuation of IV insulin occurred less frequently in post-PP patients (28% vs. 7%; P = .007), with a lower frequency of rebound DKA (40% vs. 8%; P = .001) following acute management. More post-PP patients received SC insulin >= 1 hour before discontinuation of IV insulin (65% vs. 78%; P = .05). Conclusion: Implementation of a DKA-PP was associated with appropriate discontinuation of IV insulin in more patients, more frequent administration of SC insulin >= 1 hour prior to discontinuation of IV insulin, and fewer episodes of rebound DKA.
