Our aim in this study was to describe patterns and patient-level factors associated with use of sodium/glucose cotransporter 2 inhibitors (SGLT2is) among adults with diabetes being treated in Alberta, Canada.Using linked administrative data sets from 2014 to 2019, we defined a retrospective cohort of adults with prevalent or incident type 2 diabetes with indications for SGLT2i use and who did not have advanced kidney disease (glomerular filtration rate30 mL/min per 1.73 mOf the 341,827 patients with diabetes (mean age, 60.7 years; 45.6% female), 107,244 (31.3%) had CVD. The proportion of patients with an SGLT2i prescription increased in a linear fashion to a maximum of 10.8% (95% confidence interval [CI], 10.7% to 10.9%) of the eligible cohort by the end of the observation period (March 2019). The proportion of filled prescriptions was similar for patients with CVD (10.4%; 95% CI, 10.1% to 10.6%) and for those without CVD (10.9%; 95% CI, 10.8% to 11.0%). Patients' characteristics associated with lower odds of filling an SGLT2i prescription included female sex, older age and lower income.The use of SGLT2is is increasing among patients with diabetes but remains low even in those with CVD. Policy and practice changes to increase prescribing for those in whom SGLT2is may help to reduce morbidity and mortality related to cardiovascular and renal complications, particularly older adults.

Aims To summarize methods used to account for antihyperglycemic medication changes in randomized controlled trials evaluating the effect of dietary and physical activity interventions on glycemia among adults with diabetes. Methods Using studies included in two recently published systematic reviews of randomized controlled trials examining the glycemic effects of dietary and physical activity interventions, we evaluated how each study accounted for antihyperglycemic medication changes. Data were analyzed using summary statistics, stratified by the type of intervention studied, and each was assigned a score from 0 to 6 reflecting the strength of medication controls employed. Results We evaluated 22 physical activity focused and 27 dietary focused articles. Our scoring system yielded a mean concurrent medication adjustment score of 3.9/6 for the physical activity studies and a score of 1.7/6 ( p < 0.001) for the dietary studies. Conclusions We found that randomized controlled trials included in recent systematic reviews of physical activity and dietary interventions did not robustly account or control for changes in antihyperglycemic medications, with physical activity interventions doing so more robustly than dietary interventions. This is a threat to the validity of study findings, as observed glycemic changes may in fact be attributable to imbalances in concurrent medication adjustments between groups.
