Background/Introduction
Heart failure (HF) is a major health problem due to its significant prevalence, disease burden and cost, mainly driven by high rates of hospitalization and mortality. Although numerous studies have demonstrated HF burden in western countries, data on current burden of HF in Thailand are limited.
Purpose
To describe characteristics and burden of HF, in terms of HF subgroups, hospital visits/hospitalization from HF and mortality, in participating hospitals in Thailand in 2019.
Methods
We retrospectively reviewed hospital profiles and medical records of HF adult patients at the five study sites which located in different regions across Thailand. All patients were diagnosed (newly and existing) with HF during 2018-2019, as identified by the International Classification of Diseases (ICD)-10 coding "I50". The interim data cutoff was scheduled when 4,000 patients were included. Hospital burden and the patients’ clinical and outcome data were collected and analyzed with descriptive statistics.
Results
From 4,000 patients, a total of 2,826 patients had follow-up visits in 2019 and then included in this analysis. Most of them were female (51.8%) and the overall patients’ mean (SD) age was 67.6 (15.0). Among 1,668 patients with available baseline left ventricular ejection fraction (LVEF), HF with preserved EF (HFpEF) was the most common subgroup (47.3%), followed by HF with reduced EF (HFrEF (39.0%) and HF with mid-range EF (HFmrEF) (13.7%). Of the total hospital visits from HF, 11.5% (95% CI 10.8-12.3) were from unscheduled visits to emergency or outpatient departments. HFpEF accounted for the highest number of hospital visits for HF, both scheduled and unplanned visits (46.4%, 48.9%), followed by HFrEF (39.0%, 41.5%) and HFmrEF (14.6, 9.6%), respectively. Among these 2,826 HF patients, the numbers of hospitalizations and rehospitalization from HF were 2,553 and 447. The total rate of HF rehospitalization was highest at 30 days (39.1%, 95% CI 34.6-43.7), followed by at 180 days (26.8%, 95% CI 22.7, 30.9), and 60 days (23.5%, 95% CI 19.6-27.4), respectively. The rates of all-cause and CV deaths within identified HF patients were 8.6% (95% CI 7.6-9.7) and 7.2% (95% CI 6.3-8.2). HFrEF accounted for the highest proportions of both (re) hospitalization and deaths (all-cause and CV) while HFpEF had the highest number of total beds.
Conclusion
Among the studied patients, HFpEF was the most common form of HF and HF was associated with a substantial healthcare burden in Thailand. The hospitalization rates from HF were especially high during the first 30 days after discharge, with a number of visits being unplanned or emergency visits leading to high hospital resource utilization.
