ObjectiveDiabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes (T1D). In established T1D patients, DKA is frequently a result of insulin omission or inadequate insulin administration during illness or stress. Ethnic minorities and patients with lower socioeconomic status are affected disproportionately. We hypothesized that implementation of intensive sick day rules with frequent reinforcement would reduce hospitalizations secondary to DKA in T1D youth irrespective of their demographics.MethodsIntensive sick day rules were implemented beginning January 2016. All T1D patients seen in the pediatric endocrinology clinic or hospital between January 1st 2015 through December 31st 2017 were included for chart review. Categorical variables were analyzed with Chi-square test. For the continuous variables, t test was used. Episodes of DKA per 100 patients were compared using the trends test over the three-year period. Patients who had DKA in 2015 were analyzed as a subgroup.ResultsThe frequency of DKA episodes per 100 patient years for 2015 was 19.1, for 2016 was 15.2 and was 12.4 for 2017. This decrease was statistically significant (p=0.006). The decline was also statistically significant for the subgroup of patients who developed DKA in 2015 and followed longitudinally. The decline was not uniform across all patient groups and DKA episodes remained associated with African- American race, Medicaid insurance status and higher HbA1c throughout the years.ConclusionImplementation of intensive sick day rules led to a decrease in total number of DKA admissions in our population with T1D youth. However, this intervention did not reduce the health disparity in this population and African-Americans on Medicaid insurance continued to form the disproportionate majority of admissions with DKA. This study highlights the need for further research into interventions that can improve outcomes across racial and socio-economic barriers.Copyright © 2021 National Medical Association.
