|---|---|
| Secondary Outcome | 1) Medication adherence rate for the most recent month (28 days) at 6 months 2) Occurrence of a >30% decline in eGFR at 6 months, or hyperkalemia (K >5.5 mEq/L or initiation of new potassium binders), or hypokalemia (K <3.0 mEq/L) at 6 months 3) Change in NT-proBNP at 6 months 4) Proportion with NT-proBNP increase >30% at 6 months 5) Change in GNRI at 6 months 6) All-cause mortality up to 12 months 7) Heart failure hospitalization or unscheduled visits requiring IV diuretics up to 12 months 8) Increase or initiation of diuretics other than cardiac protective drugs (GDMT) by 12 months 9) Composite event of heart failure hospitalization, unscheduled visits requiring IV diuretics, or increase/initiation of diuretics other than GDMT by 12 months 10) Hospitalization triggered by any of the following abnormalities within 12 months (fracture, fall, delirium/consciousness disturbance, cognitive decline, syncope, bleeding, infection, malnutrition/anorexia, electrolyte abnormality, blood glucose abnormality, renal impairment, hepatic impairment, drug allergy, constipation/intestinal obstruction, drug-induced movement disorder) 11) Medication adherence rate in the most recent month at 12 months 12) Change in ASK-20 score at 12 months 13) Decrease in eGFR by >30% or development of hyperkalemia/hypokalemia as of December 14) Change in NT-proBNP level at 12 months 15) Change in GNRI level at 12 months |
