Disparities in Continuous Glucose Monitoring Among Patients Receiving Care in Federally Qualified Health Centers
Authors' conclusion
In this cross-sectional study of electronic health record data, rates of CGM prescription orders were low among FQHC patients with T1D and T2D. Disparities in CGM orders were observed among patients reporting Hispanic ethnicity, Black race, and those who lacked health insurance. Future research is needed to understand the causes of infrequent CGM orders in FQHCs and drivers of observed disparities in this vulnerable patient population.
