1226-P: Effectiveness of Frequency of Visits in the Internet plus Diabetes Shared Care Clinic on Glucose Improvement in Patients with Type 2 Diabetes: A Real-World Analysis

Background: Patients with diabetes need DSMS on the basis of systematic comprehensive management. However, there is no recommendation on how often regular follow-up visits patients should receive in China.

Objectives: To explore the effectiveness of frequency of visits in the Internet plus Diabetes Shared Care (IDSC) clinic on glycemic control among patients with type 2 diabetes followed-up more than 2 years.

Design: A retrospective single-center hospital-based propensity scores weighting (PSW) real-world analysis.

Methods: IDSC in Peking University First Hospital (PKUFH) provided individualized, systematic and continuous management with off-line and on-line support. Adult patients with type 2 diabetes who received at least second follow-up visit in IDSC clinic in the first semester of 2018 were eligible. All subjects were divided into three groups by actual follow-up visit times within 2018 Jan to 2019 Jan. Age, gender, diabetes duration, baseline metabolic profiles (BMI, HbA1c, LDL-c, BP), baseline Insulin usage and baseline costs of antidiabetic drugs were used as covariates for three-group PSW analysis to compare the average treatment effect in the population (ATE) of HbA1c in each group at 1-year and 2-year follow up.

Result: A total of 496 eligible subjects were included [Fv group (Four visits/y) n=330, Tv group (Three visits/y) n=128, TLv group (Two or Less visits/y) n=38]. After PSW, HbA1c of Fv group was improved in trend at 1-year follow up compared with Tv group (-0.25%, p=0.05) and TLv group (-0.34%, p=0.06) but was significantly improved at 2-year follow up (-0.34%, p=0.01 for Tv group; -0.55%, p=0.008 for TLv group). There was no significant difference in HbA1c between the Tv group and TLv groups at neither 1-year and 2-year follow-up.

Conclusions: Our findings indicate that regularly followed-up in IDSC clinic at least 4 times/year could efficiently improve glycemic control of among patients with type 2 diabetes.
