Among adults with diabetes, we characterized the prevalence of chronic kidney disease eligible for SGLT2 inhibitor treatment, based on definitions of eligibility from trials and diabetes guidelines, and assessed the predictors of SGLT2 inhibitor use.Methods: We conducted a cross-sectional study using linked administrative data from Alberta Health in adults with diabetes (2002–2019). Chronic kidney disease was defined as an estimated glomerular filtration rate (eGFR) less than 90 mL/min/1.73 m2 with severe or greater proteinuria (trial-based definition); or eGFR less than 60 mL/min/1.73 m2 or moderate or greater proteinuria regardless of eGFR (diabetes guideline–based definition). Predictors (sociodemographic characteristics, comorbidities and health care utilization) of SGLT2 inhibitor use were identified using logistic regression.Results: Of 446 315 adults with diabetes, 76 630 (17.2%, guideline-based definition; 12 867 [2.9%], trial-based definition) had chronic kidney disease eligible for SGLT2 inhibitor treatment. A total of 7.1% used SGLT2 inhibitors. Older age, lower hemoglobin A1c (HbA1c) levels, female sex, lower neighbourhood income, rural residence and hospital admission were among variables associated with nonuse of SGLT2 inhibitors (adjusted odds ratios [ORs] from 0.13 [age ≥ 85 yr] to 0.92 [rural residence], p < 0.05). Family physician visits were associated with higher SGLT2 inhibitor use (adjusted OR 4.01, p < 0.001 for > 4 visits/yr). Considering all adults, both with and without diabetes, 162 012 individuals with chronic kidney disease (5% of all Alberta adults) may benefit from treatment with SGLT2 inhibitors.Interpretation: Many adults with chronic kidney disease would derive heart and kidney benefits from treatment with SGLT2 inhibitors but had low SGLT2 inhibitor use as of 2019. Efforts will be needed to address lower use of SGLT2 inhibitors among female, older and lower-income adults, and to enhance primary care and promote awareness of the benefits of SGLT2 inhibitors independent of glycemic control.
