PSUN193 Comparing Long-Term Outcomes of Children Diagnosed with New-Onset Type 2 Diabetes in an Outpatient vs Inpatient Setting

BACKGROUND: Early identification and treatment of children and adolescents with Type 2 Diabetes (T2DM) is thought to improve long-term outcomes. However, it is unclear if severity of T2DM at presentation affects long-term clinical outcomes. Using the location of treatment initiation (inpatient compared to outpatient) as a proxy for severity of illness, we aimed to assess changes in dysglycemia and insulin requirements at diagnosis and after 3 years of follow-up. METHODS: We performed a retrospective chart review of children 8-18 years of age diagnosed with new onset type 2 diabetes and receiving diabetes care within a large tertiary care center between 1/1/2010 and 11/1/2021 for three consecutive years. Children were identified by ICD codes (ICD9 250.00, ICD10 E13.9 or E11.9). Charts were reviewed to confirm diagnosis. Exclusion criteria included medication induced diabetes, MODY, >1 positive diabetes autoantibody, BMI<85%, complicated medical history (genetic disorders, transplant, cancer, etc.), and < 3 visits in the study time frame. Chi-squared, t-tests, ANOVA, and linear regression were used for analyses. RESULTS: A total of 513 patients were identified by ICD code and, after exclusions, 116 were included in the analysis: 69 initially treated in an inpatient setting and 47 initially treated in an outpatient setting. The average A1C at presentation was higher in the inpatient group (11.02% ± 1.77) than the outpatient group (7.19% ± 0.72) (p<0.001). The BMI z-score at presentation was lower in the inpatient group (2.17%±0.58) than the outpatient group (2.41% ±0.35) (p=0.015), but at three years of follow-up the BMI z-score between the groups was not significantly different (2.05%±0.60) compared to (2.12% ±0.50) (p = 0.536). The average A1C remained higher in the inpatient group (9.58%±2.92) compared to the outpatient group (8.43% ±2.44) (p = 0.031). At treatment initiation the average total daily dose of insulin in the inpatient group (0.68±0.36 units/kg/day) was higher than the outpatient group (0.05±0.18 units/kg/day) (p<0.001). At three years of follow-up the average total daily dose of insulin remained higher in the inpatient group (0.50±0.46 units/kg/day) compared to the outpatient (0.29±0.36) (p=0.008 units/kg/day) group. CONCLUSION: In conclusion, pediatric patients initially treated in the inpatient setting had poorer glycemic control and higher insulin requirements at baseline that persisted after three years of follow-up. These findings suggest that initial presentation may predict long-term clinical outcomes in children with T2DM. Presentation: Sunday, June 12, 2022 12:30 p.m. - 2:30 p.m.
