Abstract
Abstract Background There is a concern regarding socioeconomic disparities in prescription of new medications such as SGLT-2is or GLP-1RAs in type 2 diabetes mellitus (T2DM). This study aims to analyze prescription patterns of these medications 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’ electronic health record data. Socioeconomic status (SES) was based on standardized disposable household income in quintiles. The association between SES and the prescription of SGLT-2is and GLP-1RAs in 2022 was investigated by logistic regression analyses, adjusting for potential confounding factors. SGLT-2is and GLP-1RAs prescription patterns were examined over 2019-2022, stratified for age-groups and sex. Results We found a positive association between SES quintile 1 (referent) and quintile 4 in SGLT-2is prescription in all models (OR 1.29 95%CI:1.08-1.54 in the fully adjusted model). For prescriptions of GLP-1RAs, we found no significant differences in SES. Proportionally, men are more frequently prescribed SGLT-2is, while there are no sex disparities in GLP-1RAs prescription. Older individuals consistently receive fewer SGLT-2is and GLP-1RAs prescriptions compared to other age categories. Conclusions We observed sex and age disparities but no profound socioeconomic differences in initiation of SGLT-2is and GLP-1RAs in the Netherlands. The latter may be due to guidelines’ clear indication of the eligible population (T2DM and very high cardiovascular risk) and GP education. Future development and potential disparities in initiation and maintenance should be monitored. Key messages • We found no disparities in prescribing new Type 2 diabetes medication based on socioeconomic status. • The adoption of prescribing new medication for Type 2 diabetes patients takes time.
