The incremental economic burden of heart failure: A population-based investigation from South Korea.

ABSTRACT: BACKGROUND:The prevalence of heart failure (HF) and its economic burden are increasing with age of the South Korean population. This study aimed to assess the economic impact of HF from the societal perspective. METHODS:A prevalence-based, incremental cost-of-patient study was performed to estimate the cost ratio between patients with HF and those without HF based on the claims database of the national health insurance in South Korea. We defined adult HF patients as those aged ?19 years who had at least one insurance claim record with a primary or secondary diagnosis of HF. Age- and gender-matched controls were defined using a 1:4 greedy matching method. Costs were estimated by including medical costs for insurance-covered and non-covered services, transportation costs, caregiver's cost, and time costs of patients. The ratio of costs between patients with HF and those without HF was adjusted for age, gender, and type of universal health security program in the multivariate regression model. RESULTS:The average annual per-capita cost was estimated to be $6,601 for patients with HF (n = 14,252), which is about 3.38 (95% confidence interval [CI]: 3.31-3.46) times higher than that for patients without HF (n = 1,116,882) and 1.64 (95% CI: 1.59-1.70) times higher than that for the age- and gender-matched patients without HF (n = 57,008). In the multivariate regression model, the annual per-capita total costs were 1.98-fold (95% CI: 1.94-2.02) statistically higher for patients with HF than for patients without HF after adjustment for age, gender, and type of universal health security program. CONCLUSIONS:This study demonstrates a significant incremental burden of HF. Given that the prevalence of HF is expected to increase with an increase in the aging population, the national economic burden is expected to be substantial in the future. Thus, greater emphasis on the prevention and treatment of HF is warranted.

Project description:We evaluated the survival rates and medical expenditure in patients with lung cancer using a nationwide claims database in South Korea. A retrospective observational cohort study design was used, and 2,919 lung cancer patients and their matched controls were included. Medical expenditures were analyzed with the Kaplan-Meier sample average method, and patients were categorized into 4 groups by operation and primary treatment method (i.e. Patients with operation: OP = surgery, OP+CTx/RTx = surgery with anti-cancer drugs or radiotherapy; Patients without operation: CTx/RTx = anti-cancer drugs or radiotherapy, Supportive treatment). The 5-year medical expenditure per case was highest in the OP+CTx/RTx group ($36,013), followed by the CTx/RTx ($23,134), OP ($22,686), and supportive treatment group ($3,700). Lung cancer-related anti-cancer drug therapy was the major cost driver, with an average 53% share across all patients. Generalized linear regression revealed that monthly medical expenditure in lung cancer patients, after adjustment for follow-up month, was approximately 3.1-4.3 times higher than that in the control group (cost ratio for OP = 3.116, OP+CTx/RTx = 3.566, CTx/RTx = 4.340, supportive treatment = 4.157). The monthly medical expenditure at end of life was estimated at $2,139 for all decedents, and approximately a quarter of patients had received chemotherapy in the last 3 months. In conclusion, this study presented the quantified treatment costs of lung cancer on various aspects compared with matched controls according to the treatment of choice. In this study, patients with operation incurred lower lifetime treatment costs than patients with CTx/RTx or supportive treatment, indicating that the economic burden of lung cancer was affected by treatment method. Further studies including both cancer stage and treatment modality are needed to confirm these results and to provide more information on the economic burden according to disease severity.

Project description:IntroductionA worsening heart failure event (WHFE) is defined as progressively escalating heart failure signs/symptoms requiring intravenous diuretic treatment or hospitalization. No studies have compared the burden of chronic heart failure with reduced ejection fraction (HFrEF) following a WHFE versus stable disease to inform healthcare decision makers.MethodsA retrospective study using the IBM® MarketScan® Commercial Database included patients younger than 65 years of age with HFrEF (one inpatient or two outpatient claims of systolic HF or one outpatient claim of systolic HF plus one outpatient claim of any HF). The first claim for HFrEF during 2016 was the index date. Patients were followed for the first 12 months after the index date (the worsening assessment period) to identify a WHFE, and for an additional 12 months or until the end of continuous enrollment (the post-worsening assessment period). Mean per patient per month (PPPM) health care resource use (HCRU) and costs were compared between patients following a WHFE and stable patients during the two periods using generalized linear models adjusting for patient characteristics.ResultsOf 16,646 patients with chronic HFrEF, 26.8% developed a WHFE. Adjusted all-cause hospitalizations (0.16 vs. 0.02 PPPM, P < 0.0001), outpatient visits (3.54 vs. 2.73 PPPM, P < 0.0001), and emergency department visits (0.25 vs. 0.06 PPPM, P < 0.0001) were higher in patients following a WHFE than stable patients during the worsening assessment period. Similar differences in HCRU were observed between the two cohorts during the post-worsening assessment period. Mean total adjusted cost of care PPPM was $8657 in patients with HFrEF following a WHFE versus $2195 in stable patients during the worsening assessment period, and $6809 versus $2849, respectively, during the post-worsening assessment period.ConclusionHCRU and costs were significantly greater in patients with chronic HFrEF following a WHFE compared to those who remained stable, suggesting an unmet need to improve clinical and economic outcomes among these patients.
