BackgroundIn people with type 2 diabetes at high risk of cardiovascular or kidney disease, sodium-glucose co-transporter 2 (SGLT2) inhibitors consistently reduce the risk of hospitalisations for heart failure. Less is known about their effects on hospitalisation from any cause, especially in people with type 2 diabetes without atherosclerotic cardiovascular disease, which includes most of the global population of people with type 2 diabetes. We aimed to assess the effect of the SGLT2 inhibitor, dapagliflozin, on the risks of hospitalisations for any cause and for specific causes in people with type 2 diabetes with and without atherosclerotic cardiovascular disease.MethodsThe DECLARE-TIMI 58 trial was a double-blind, multicentre, randomised, placebo-controlled study. People with type 2 diabetes and either risk factors for or established atherosclerotic cardiovascular disease were randomly assigned (1:1) to receive oral dapagliflozin 10 mg or placebo once daily. In these post-hoc analyses, the effects of dapagliflozin on risks of first non-elective any-cause and cause-specific hospitalisation were assessed with Cox proportional hazards regression models overall and in the subset of participants without prevalent atherosclerotic cardiovascular disease. The risk of total (first plus subsequent) non-elective hospitalisations was assessed with Lin-Wei-Ying-Yang model. Investigator-reported System Organ Class terms were used to classify cause-specific hospitalisations. The trial is registered with ClinicalTrials.gov, NCT01730534.FindingsBetween April 25, 2013, and Sept 18, 2018, 17 160 people (6422 [37·4%] women, 10 738 [62·6%] men; mean age 63·9 years [SD 6·8]) were enrolled in the original trial, of whom 10186 (59·4%) had multiple risk factors for but did not have established atherosclerotic cardiovascular disease, and 6835 (39·8%) had both no evidence of atherosclerotic cardiovascular disease and low KDIGO risk. Over a median follow-up of 4·2 years (IQR 3·9–4·4), dapagliflozin was associated with a lower risk of first non-elective hospitalisation for any cause (2779 [32·4%] of 8582 people in the dapagliflozin group vs 3036 [35·4%] of 8578 people in the placebo group; hazard ratio [HR] 0·89 [95% CI 0·85–0·94]) and total (first plus subsequent) non-elective hospitalisations for any cause (risk ratio 0·92 [95% CI 0·86–0·97]). The association between dapagliflozin use and the risk of first non-elective hospitalisation for any cause was consistent in subgroups of participants with (HR 0·92 [95% CI 0·85–0·99] and without (0·87 [0·81–0·94]) atherosclerotic cardiovascular disease at baseline (p interaction=0·31). Compared with the placebo group, the dapagliflozin group had lower risk of first hospitalisations due to cardiac disorders (HR 0·91 [95% CI 0·84–1·00]), metabolism and nutrition disorders (0·73 [0·60–0·89]), renal and urinary disorders (0·61 [0·49–0·77]), and due to any other cause excluding these three causes (0·90 [0·85–0·96]). Treatment with dapagliflozin was also associated with a lower risk of hospitalisations due to musculoskeletal and connective tissue disorders (HR 0·81 [0·67–0·99]) and infections and infastations (HR 0·86 [0·78–0·96]).InterpretationDapagliflozin reduced the risk of first and total non-elective hospitalisations for any cause in people with type 2 diabetes, regardless of the presence of atherosclerotic cardiovascular disease, including hospitalisations not directly attributed to cardiac, kidney, or metabolic causes. These findings might have implications on health-related quality of life for people with type 2 diabetes and on health-care costs attributable this condition.
