RESUMO
OBJECTIVES: Our objectives were to characterize variations from standardized, evidence-based guidelines in the management of pediatric patients with diabetic ketoacidosis (DKA) based on initial presentation to a tertiary pediatric emergency department (PED) versus a community emergency department (OSH) and compare clinical outcomes. METHODS: We conducted a retrospective study on children 18 years and younger with DKA who presented to an OSH or PED over a 3-year period. Treatments monitored for variation included intravenous fluid management, insulin delivery, and sodium bicarbonate administrations. Clinical outcomes included time to anion gap correction and on insulin infusion, hypokalemia, hypoglycemia, rapid serum glucose decline, cerebral edema, mechanical ventilation, mortality, and time from initial presentation to hospital discharge. RESULTS: Children with DKA who presented to an OSH (n = 250) were more acidotic (pH 7.11 vs. 7.13, P = 0.001) and had larger anion gaps (28.8 vs. 25.5, P < 0.001) compared with children presenting to the PED (n = 237). The OSH patients were more likely to receive larger fluid boluses (>20 cc/kg or >1000 ml, 43% vs. 4%, P < 0.001), sodium bicarbonate (5% vs. 0%, P < 0.001), and intravenous bolus insulin (28% vs. 0%, P < 0.001). The OSH group were less likely to be started on maintenance intravenous fluids (70% vs. 99%, P < 0.001) or receive potassium in maintenance intravenous fluids (14% vs. 42%, P < 0.001). The OSH group had longer anion gap correction times (754 vs. 541 mins, P < 0.001), insulin infusion times (1018 vs. 854 min, P = 0.003), and times to hospital discharge (3358 vs. 3045 mins, P < 0.001). Incidence of hypokalemia, hypoglycemia, rapid glucose decline, cerebral edema, and deaths were similar between the 2 groups. CONCLUSIONS: Our study demonstrated significant variations in the initial management of pediatric DKA patients by OSH facilities that deviated from an evidence-based treatment pathway utilized by a PED. Statewide quality improvement initiatives could help improve the overall clinical care provided to pediatric DKA patients.
