Insights
Congestive heart failure (CHF) significantly increases healthcare costs, with patients incurring two to three times higher expenses than those without the condition. This highlights opportunities for cost control in managing CHF patients.
Area of Science:
- Cardiology
- Health Economics
Background:
- Congestive heart failure (CHF) is a leading cause of hospital admissions.
- The economic burden of ambulatory care for CHF is less understood.
- This study assesses the comprehensive direct medical costs of CHF.
Purpose of the Study:
- To evaluate the relative burden and direct medical costs of congestive heart failure (CHF).
- To compare healthcare utilization and costs between CHF patients and matched controls.
- To analyze costs across inpatient and outpatient settings.
Main Methods:
- Utilized longitudinal clinical data from a large Israeli health organization (2006-2012).
- Identified and matched adults with newly diagnosed CHF to controls without CHF.
- Compared healthcare utilization and costs, excluding individuals in their final year of life.
Main Results:
- CHF patients (n=6592) showed significantly higher comorbidity and healthcare utilization than controls (n=32,960).
- Costs were elevated across all service categories (inpatient, outpatient, medications, labs) for CHF patients.
- CHF patients incurred 2.08 to 3.25 times higher healthcare costs compared to non-CHF individuals, varying by age.
Conclusions:
- Congestive heart failure (CHF) is associated with a 2-3 fold increase in healthcare costs.
- CHF accounts for over half of healthcare costs in elderly patients and two-thirds in younger patients.
- Findings suggest significant opportunities for cost containment in managing CHF, particularly in younger populations.
Background:
Congestive heart failure (CHF) is among the most common causes of hospital admissions and readmissions in the Western world. However, the burden of ambulatory care has not been as well investigated. The objective of this study was to assess the relative burden and direct medical costs of CHF including inpatient and outpatient care.
Methods:
We used longitudinal clinical data from a two-million member health organization in Israel (Maccabi Healthcare Services) to identify adults with newly diagnosed CHF between January 2006 and December 2012, either in the in- or outpatient setting. Adults without CHF were age- and sex-matched to CHF patients and healthcare utilization and all modes of healthcare costs were compared among them, excluding those in their last year of life.
Results:
The burden posed by 6592 CHF patients was significantly (p < 0.001) larger than that of 32,960 matched controls. CHF patients had significantly higher rates of baseline comorbidity and healthcare utilization compared to non-CHF controls. This was evident in all categories of healthcare services and expenses, including in- and outpatient visits, laboratory expenses, medication costs, among younger and older, men and women. Among those who incurred any healthcare costs, younger (45-64y) and older (65 + y) subjects with CHF were observed to have about 3.25 (95% CI: 2.96-3.56) and 2.08 (95% CI: 1.99-2.17) times the healthcare costs, respectively, compared to subjects without CHF after adjusting for patient characteristics.
Conclusion:
CHF is associated with an overall two- to three-fold higher cost of healthcare services depending on patient age, accounting for over half of all healthcare costs incurred by elderly CHF patients, and more than two-thirds of all costs among younger CHF patients. Observations of the large burden posed on one of the youngest societies in the developed world are profound, implicative of great opportunities to control the costs of CHF. Further research to understand how resource use impacts health outcomes and quality of care is warranted.
