Effect of a Disease Management Program on the Adherence to Guideline-Recommended HbA1c Monitoring in Patients with Diabetes in Slovakia.

INTRODUCTION

Glycated hemoglobin (HbA1c) is a crucial marker of glucose control that is widely utilized in the management of diabetes mellitus. The aim of this study was to evaluate the effect of a diabetes management program (DMP) offered by a health insurance company, together with the effects of other factors associated with patient and physician characteristics, on the frequency of HbA1c testing in outpatient diabetes clinics in Slovakia.

METHODS

A retrospective analysis was conducted to compare the frequency of HbA1c measurements in patients under the care of physicians participating in the DMP with those who did not, spanning the years 2015 to 2019. In 2019, a total of 74,384 patients with diabetes were included in the analysis, of which 52% were men and 48% were women, with an average age of 64.1 years.

RESULTS

At the end of the study period, the average annual number of HbA1c measurements was significantly higher in patients treated by physicians participating in the DMP than in patients treated by physicians who were not (2.50 vs. 1.91 per year, respectively; P < 0.001). There was a substantial increase in HbA1c testing at least twice yearly in both groups, but the growth rate was greater in the group with DMP-engaged diabetologists (14.3%) compared to the diabetes specialists who were not involved in the DMP (5.1%). In the multivariate analysis, participation in the DMP was correlated with an increase in HbA1c tests per year by 0.7.

CONCLUSIONS

Physician participation in a DMP was found to significantly increase the number of HbA1c tests ordered by physicians, potentially leading to improved glycemic control.
