Investigating socioeconomic disparities in prescribing new diabetes medications in individuals with type 2 diabetes and very high cardiovascular risk in the Netherlands.

Abstract

Aims: This study aims to analyze prescription patterns of new diabetes medication and assess socioeconomic disparities in their initiation among individuals with T2DM with very high cardiovascular risk.

Methods: Individuals diagnosed with T2DM and very high cardiovascular risk were identified (N = 10,768) based on general practitioner's electronic health record data. SGLT-2is and GLP-1RAs prescription patterns were examined. Furthermore, the association between SES and the prescription of SGLT-2is and GLP-1RAs in 2022 was investigated.

Results: Despite the increase in prescription rates of SGLT-2is and GLP-1RAs between 2019 and 2022, approximately 85 % and 93 % of eligible individuals did not receive SGLT-2is and GLP-1RAs in 2022, respectively. We found a positive association between SGLT-2is prescription and SES in only the 4th quintile compared to 1st quintile (referent) in the fully adjusted model (OR 1.29 95 % CI:1.08-1.54).

Conclusions: The prescription rates among eligible individuals highlight significant room for improvement in aligning prescribing practices with guidelines. We found no profound socioeconomic gradient in initiation of SGLT-2is and GLP-1RAs. The latter may be due to guidelines' clear indication of the eligible population and GP education. Future development and potential disparities in initiation and maintenance should be monitored to ensure equitable prescribing.
