Using Quality Improvement to Design and Evaluate an Outpatient Day Treatment Pathway for Pediatric Patients with Diabetes Mellitus Requiring Insulin Initiation.

Introduction: Education and management of children with new-onset or established diabetes mellitus (DM) requiring insulin initiation do not always require hospitalization. We developed a pathway for outpatient day treatment of select patients after initial evaluation in the emergency department (ED) at a pediatric, tertiary care academic medical center. Methods: A multidisciplinary team identified key initial eligibility criteria for outpatient day treatment for insulin initiation, including absence of diabetic ketoacidosis, age ≥3 years, and plasma beta-hydroxybutyrate (BOHB) <1 mmol/L. Electronic medical record reviews and surveys administered to endocrine providers determined exclusions or reasons for nonparticipation. Refinement of the pathway occurred through iterative plan-do-study-act cycles. Statistical process control evaluated the uptake among eligible patients. Results: We launched the pathway in September 2020. Of 534 patients presenting to the ED with new-onset or established DM requiring insulin initiation in the first 2.5 years, 198 were potentially eligible for day treatment. Of these, 65 children (33%) completed the pathway. One additional patient was hospitalized following Day 1 of education due to newly identified psychosocial stressors. The increase of BOHB cutoff to 1.5 mmol/L and the option of rapid-acting insulin bolus for borderline BOHB resulted in a significant shift in utilization from a mean of 24.4% to 41.1%. Persistent barriers to participation include limited appointment availability, weekend presentation, and patient/family concerns. Conclusions: Outpatient day treatment was successful for select pediatric patients with new-onset or established DM requiring insulin initiation. However, this approach necessitates flexible resources and supportive patient messaging.
