Quality of care delivery in patients with acute heart failure: insights from the international REPORT-HF registry

Background: Heart Failure (HF) quality of care (QoC) is associated with clinical outcomes. Therefore, we investigated differences in HF QoC across worldwide regions (with differing national income) and the association of quality indicators with outcomes. Methods: We examined the quality of care (QoC) in acute heart failure (HF) patients across different regions using quality indicators (QIs) from the European Society of Cardiology (ESC) and the American Heart Association (AHA) to evaluate QoC. The analysis included 17,632 patients enrolled from 358 medical centres in 44 countries between 23 July 2014 and 24 March 2017, all part of the prospective REPORT-HF cohort study. We investigated how QoC varied by region and its relationship with mortality rates at 30 days and 1 year after hospital discharge. For each QI, percentage attainment of QI among eligible patients was calculated and compared across regions. Findings: Among 17,632 patients (median age: 67 years; 61% women) followed up for a median of two years, we assessed 16 QIs. QIs that were least often achieved included measurement of natriuretic peptides, performance of echocardiography, treatment with guideline medical therapy, and a scheduled follow-up consultation after discharge. QI achievement was significantly lower in lower-than higher-income countries. Higher (≥50% vs. <50%) achievement of cumulative QIs was associated with lower 30-day (hazard ratio HR 0.58, 95% Confidence Interval CI 0.40-0.83; p < 0.001), and 1-year mortality (HR 0.58, 95% CI 0.50-0.68; p < 0.001). Interpretation: QoC is lower in lower-than higher-income countries and lower QoC is associated with worse outcomes. Improving QoC by addressing structural barriers and quality improvement programs may improve the outcomes of patients with HF. Funding: Novartis.
