A comprehensive heart failure care chain should contain a tightly interconnected process, integrate related services within and outside an organization, and provide continuous care. Using the three major frameworks of the Heart Failure Disease Care Certification, National Taiwan University Hospital (NTUH) comprehensively examined the status quo of heart failure care operation. After the NTUH medical team implemented the certification, the mortality rate of patients with heart failure with an ejection fraction of ≤40% as their principal diagnosis decreased from 15.1% to 13.0%; the percentage of guideline-directed medical treatment with renin-angiotensin system-acting agents and beta-blockers increased from 28.5% to 40.0%; the percentage of using magnetic resonance angiography increased from 60.0% to 68.8 %; and the percentage of patients receiving rehabilitation increased significantly from 9.3% to 18.60%. NTUH improved the care process through the certification, which helped clinical staff to integrate heart failure care into actual care.
