Objective: To assess safety and efficacy compared to a historical cohort. Clinical practice guidelines recommend that patients with diabetic ketoacidosis (DKA) be treated with a standardized protocol. We created a multifaceted order set to promote best-practice management of DKA.
Methods: We performed a retrospective cohort study of admissions to internal medicine for DKA in adults during a 4.5-year period; 2.25 years before and after order-set initiation. Groups were compared using independent samples t tests and Pearson chi-square or Fisher exact test (categorical data). The Mann-Whitney U test was used for continuous data not normally distributed.
Results: The order-set cohort consisted of 47 admissions, 72.3% with type 1 and 27.7% with type 2 diabetes. The historical cohort consisted of 59 admissions, 69.5% with type 1 and 30.5% with type 2 diabetes. There were no significant differences in initial laboratory values between patients with type 1 and type 2 diabetes in both cohorts. The median length of hospital stay approached significance in the order-set cohort: 3.53 days (2.5 to 5.1); in the historical cohort, the median length of stay was 4.6 days (2.44 to 8.99) (p=0.102).
Conclusion: A standardized DKA order set was as effective and safe in type 1 and type 2 diabetes as individual physician management in an academic care setting. Further study is needed to assess its value in community hospital settings with less expertise and fewer diabetes specialty services.
