Aim Studies examining the safety and effectiveness of sodium‐glucose cotransporter‐2 inhibitors (SGLT2is) versus glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) among community‐dwelling adults may not generalize to nursing home (NH) residents, who are typically older and more multimorbid. We compared the safety and cardiovascular effectiveness of SGLT2is and GLP‐1RAs among US NH residents. Materials and Methods Eligible individuals were aged ≥66 years with type 2 diabetes mellitus and initiated an SGLT2i or GLP‐1RA in an NH between 2013 and 2018. Safety outcomes included fall‐related injuries, hypoglycaemia, diabetic ketoacidosis (DKA), urinary tract infection or genital infection, and acute kidney injury in the year following treatment initiation. Cardiovascular effectiveness outcomes included death, major adverse cardiovascular events and hospitalization for heart failure. Per‐protocol adjusted hazard ratios (HR) were calculated using stabilized inverse probability of treatment and censoring weighted cause‐specific hazard regression models accounting for 127 covariates. Results The study population included 7710 residents (31.08% SGLT2i, 68.92% GLP‐1RA). Compared with GLP‐1RA initiators, SGLT2i initiators had higher rates of DKA (HR 1.95, 95% confidence limits 1.27, 2.99) and death (HR 1.18, 95% confidence limits 1.02, 1.36). Rates of urinary tract infection or genital infection, acute kidney injury, major adverse cardiovascular events, and heart failure were also elevated, while rates of fall‐related injuries and hypoglycaemia were reduced, but all estimates were imprecise and highly compatible with no difference. Conclusions SGLT2is do not have superior, and may have inferior, effectiveness compared with GLP‐1RAs for cardiovascular and mortality outcomes in NH residents. Residents initiating SGLT2is should be monitored closely for DKA.
