The economic burden of hypertension in rural south‐west China

Abstract

Abstractobjective To estimate the economic burden of hypertension in a given year in rural Yunnan Province of China, including direct, indirect and intangible costs.methods A prevalence-based cost-of-illness method was used to estimate the economic burden of hypertension. Data on participants' demographic characteristics, inpatient hospitalisation expenditures, outpatient visit expenditures, self-medication costs and indirect costs related to hypertension were collected from a cross-sectional health examination and questionnaire survey, involving 9396 consenting individuals aged ‡18 years and 3500 households. Blood pressure (BP) levels were determined from the average of three BP measurements. Years of life lost (YLL) because of hypertension was estimated using medical death certificates.results The overall prevalence of and YLL ⁄ 1000 population because of hypertension was 24.8% and 1.5 years for the survey population, respectively. Mean unit direct medical costs, direct non-medical costs, morbidity costs, mortality costs, intangible costs and cost of illness were estimated to be $467.2, $20.1, $23.5, $8265.1, $417.4 and $9393.3, respectively. The total cost of hypertension was estimated to be $231.7 million. Direct costs represented the largest component of economic cost of hypertension. On average, males had higher overall direct, indirect and intangible costs of hypertension than females. Both indirect and intangible costs decreased with age, whereas direct costs increased with age. The incidence of household catastrophic health payment and household impoverishment because of hypertension was 8.9% and 4.1%, respectively.

Global budget payment system helps to reduce outpatient medical expenditure of hypertension in China

“…Our data confirms previous research that direct hypertension expenditure increases with age (Le et al 2012). As hypertensive patients get older, severity of the disease and relative complications tend to increase, which can lead to concomitant rising expenditure.…”

Direct costs of hypertensive patients admitted to hospital in Vietnam’ a bottom-up micro-costing analysis

“…In the Eastern European and Central Asian regions, high blood pressure is estimated to directly or indirectly account for 25% of all health expenditures [3]. In Southwest China, a cost-of-illness analysis from the societal perspective in 2010 estimated the cost of hypertension to be US$9,393 per patient [4]. In the Philippines, a health insurance company reported reimbursement for hypertension- related diagnoses during 3.5 years to be US$56 million for 360,016 patients [5].…”

Health system strengthening and hypertension awareness, treatment and control: data from the China Health and Retirement Longitudinal Study

“…In a study conducted in rural China, for example, it was estimated that 4.1% of households suffered impoverishment as a result of hypertension. 21 The prevention and control of noncommunicable diseases have been on China's policy agenda for decades. 22 In 2009, however, there was a huge reform of the national health system.…”
