Despite large, randomized controlled trials and guideline recommendations, patients with heart failure with reduced ejection fraction (HFrEF) continue to receive suboptimal guideline-directed medical treatment (GDMT). This study aimed to evaluate the potential effect of inpatient initiation of sodium-glucose cotransport-2 (SGLT2) inhibitors on postdischarge prescribing rates and the downstream impact on clinical outcomes. The INitiation of SGlt2i in Hospital for HFrEF (INSIGHT-HF) study was a retrospective analysis of hospitalized patients older than 18 years with a left ventricular ejection fraction (LVEF) ≤40% conducted from July 2020 and July 2021. Our primary outcome was SGLT2i prescription rates at 30 days. Among 2,663 eligible patients with documented HFrEF, 177 (6.6%) had SGLT2i initiated during their index hospitalization. The rate of SGLT2i prescriptions at 30 days was significantly higher in those with inpatient initiation of SGLT2i compared with those who did not start while inpatient (96% vs 14.7%, p <0.0001). The heart failure readmission rate in the first 30 days was significantly lower in those with inpatient initiation of SGLT2i compared with those who did not start during hospitalization. (9.3% vs 22.7%, p = 0.04). Cardiovascular mortality was numerically, but not significantly, different between groups (4% vs 10.7%, p = 0.21). Inpatient initiation of an SGLT2i was associated with a significantly higher postdischarge rate of SGLT2i prescriptions and significantly lower heart failure readmission rates at 30 days. In conclusion, these findings highlight the importance of initiating SGLT2i during inpatient hospitalization to improve the quality of care in patients with HFrEF.
