A Quality Improvement Initiative to Reduce Hospitalizations for Low-risk Diabetic Ketoacidosis.

BACKGROUND AND OBJECTIVES

Children with established type 1 diabetes (T1D) who present to the emergency department (ED) with mild diabetic ketoacidosis (DKA) are often hospitalized, although outpatient management may be appropriate. Our aim was to reduce hospitalization rates for children with established T1D presenting to our ED with mild DKA who were considered low risk for progression of illness.

METHODS

We conducted a quality improvement initiative between January 1, 2012, and December 31, 2018 among children and young adults ≤21 years of age with established T1D presenting to our tertiary care ED with low-risk DKA. Children transferred to our institution were excluded. DKA severity was classified as low, medium, or high risk on the basis of laboratory and clinical criteria. Our quality improvement initiative consisted of development and implementation of an evidence-based treatment guideline after review by a multidisciplinary team. Our primary outcome was hospitalization rate, and our balancing measure was 3-day ED revisits. Statistical process control methods were used to evaluate outcome changes.

RESULTS

We identified 165 patients presenting with low-risk DKA. The baseline preimplementation hospitalization rate was 74% (95% confidence interval 64%-82%), and after implementation, this decreased to 55% (95% confidence interval 42%-67%) (-19%; = .011). The postimplementation hospitalization rate revealed special cause variation. One patient in the postimplementation period returned to the ED within 3 days but did not have DKA and was not hospitalized.

CONCLUSIONS

Hospitalization rates for children and young adults presenting to the ED with low-risk DKA can be safely reduced without an increase in ED revisits.
