Health Services Costs of Clinical Heart Failure With Reduced Ejection Fraction in Singapore

Abstract

Objectives

This study aimed to estimate the annual healthcare burden of heart failure (HF) with reduced ejection fraction (<40%) in Singapore.

Methods

Retrospective longitudinal descriptive cohort study was conducted using a linked national administrative data set (Singapore Cardiovascular Longitudinal Outcomes Database). In Singapore, during 2011, there were a total of 3267 HF-related hospital admissions. Among these, 1631 patients (49.9%), who had an ejection fraction of less than 40%, were followed up for 9 years. The primary outcomes were annual healthcare costs related to hospital admissions and outpatient visits.

Results

There was a consistent decline in HF-related hospital admissions over the years, and the average per-hospital admission cost and average cost per day for HF varied over the 9 years. The average all-cause per-patient admission cost remained stable annually, ranging between S$16 000 and S$18 800. In the final year of life, there was a significant increase in both all-cause and HF-related hospital admission costs (by 24% and 54% from the previous year, respectively), and this rise in costs reflected increased frequency of admissions and longer hospital stays. There was an upward trend in the cost of outpatient visits as the patients neared death.

Conclusions

Hospital-based HF care imposes a significant financial impact on Singapore’s healthcare system. This suggests a need for cost-efficient management strategies to reduce the reliance on hospital-based treatment, thus mitigating economic pressures on the healthcare system.
