Self-identified prescriber tendencies in sodium-glucose cotransporter-2 inhibitor outpatient prescribing

Abstract

BackgroundDespite expanded indications and demonstrated cardiovascular and renal benefits, prescribing rates of sodium-glucose cotransporter-2 (SGLT-2) inhibitors are low. ObjectivesThe study aimed to identify factors impacting prescriber decision-making when prescribing SGLT-2 inhibitors in the outpatient setting and identify differences across specialties in self-identified prescribing patterns. MethodsAn anonymous survey was administered electronically to prescribers in relevant specialties at a large community health system. Descriptive statistics were used to compile results, and subgroup comparisons were conducted utilizing Fisher’s exact test. ResultsFifty-one prescribers completed the survey, representing a 25.2% response rate. The highest reported prescribing rates were for type 2 diabetes (92%), and the lowest for HFpEF (20%) and ASCVD risk reduction (16%). Prescribers without clinic-embedded pharmacist were more likely to report cost and insurance had at least a moderate effect on prescribing compared to prescribers with clinic-embedded pharmacists (95.3% vs. 62.5%, P = 0.0228) and less likely to report hemoglobin A1c less than 6.5% to have at least a moderate effect on prescribing (20.9% vs. 62.5%, P = 0.0317). Compared to specialty providers, primary care prescribers were more likely to report hemoglobin A1c over 9% had at least a moderate effect on prescribing (92.0% vs. 42.9%, P = 0.0082) and less likely to note history of urinary tract infection (22.2% vs. 85.7%, P = 0.0028), history of mycotic infection (38.9% vs. 100%, P = 0.0036), and sex (male: 5.6% vs. 42.9%, P = 0.0242; female: 8.0% vs. 42.9%, P = 0.0447) had at least a moderate effect on prescribing. ConclusionPrescribing hesitancies vary across specialty and when clinic-embedded pharmacists are present. Pharmacists may help improve SGLT-2 inhibitor prescribing rates and use of guideline-directed therapies. Pharmacists can target identified hesitancies through medication-access consultations, education regarding adverse effects, and expanded benefits of the class. Future studies should examine the impact of pharmacist intervention on SGLT-2 inhibitor prescribing rates.
