Annual Total Medical Expenditures Associated with Hypertension by Diabetes Status in U.S. Adults.

ABSTRACT: Hypertension and diabetes, both independent risk factors for cardiovascular disease, often coexist. The hypertension-increased medical expenditures by diabetes status is unclear, however. This study estimated annual total medical expenditures in U.S. adults by hypertension and diabetes status.The study population consisted of 40,746 civilian, non-institutionalized adults aged ?18 years who participated in the 2013 or 2014 Medical Expenditure Panel Survey. The authors separately estimated hypertension-increased medical expenditures using two-part econometric and generalized linear models for the total; diabetes (n=4,396); and non-diabetes (n=36,250) populations and adjusted the results into 2014 U.S. dollars. Data were analyzed in 2017 and estimated the hypertension-increased medical expenditures by type of medical service and payment source.The prevalence of hypertension was 34.9%, 78.3%, and 30.1% for the total, diabetes, and non-diabetes populations, respectively. The respective mean unadjusted annual per capita medical expenditures were $5,225, $12,715, and $4,390. After controlling for potential confounders, hypertension-increased expenditures were $2,565, $4,434, and $2,276 for total, diabetes, and non-diabetes populations, respectively (all p<0.001). The hypertension-increased expenditure was highest for inpatient stays among the diabetes population ($1,730, p<0.001), and highest for medication among the non-diabetes population ($687, p<0.001). By payment source, Medicare ranked first in hypertension-increased expenditures for the diabetes ($2,753) and second for the non-diabetes ($669) populations (both p<0.001).Hypertension-increased medical expenditures were substantial and varied by medical service type and payment sources. These findings may be useful as inputs for cost- effectiveness evaluations of hypertension interventions by diabetes status.

Project description:BackgroundThe prevalence of obesity has more than doubled in the USA in the past 30 years. Obesity is a significant risk factor for diabetes, cardiovascular disease, and other clinically significant co-morbidities. This paper estimates the medical care cost savings that can be achieved from a given amount of weight loss by people with different starting values of body mass index (BMI), for those with and without diabetes. This information is an important input into analyses of the cost effectiveness of obesity treatments and prevention programs.MethodsTwo-part models of instrumental variables were estimated using data from the Medical Expenditure Panel Survey (MEPS) for 2000-2010. Models were estimated for all adults as well as separately for those with and without diabetes. We calculated the causal impact of changes in BMI on medical care expenditures, cost savings for specific changes in BMI (5, 10, 15, and 20 %) from starting BMI levels ranging from 30 to 45 kg/m(2), as well as the total excess medical care expenditures caused by obesity.ResultsIn the USA, adult obesity raised annual medical care costs by $US3,508 per obese individual, for a nationwide total of $US315.8 billion (year 2010 values). However, the relationship of medical care costs over BMI is J-shaped; costs rise exponentially in the range of class 2 and 3 obesity (BMI ≥35). The heavier the obese individual, the greater the reduction in medical care costs associated with a given percent reduction in BMI. Medical care expenditures are higher, and rise more with BMI, among individuals with diabetes than among those without diabetes.ConclusionsThe savings from a given percent reduction in BMI are greater the heavier the obese individual, and are greater for those with diabetes than for those without diabetes. The results provide health insurers, employers, government agencies, and health economists with accurate estimates of the change in medical care expenditures resulting from weight loss, which is important information for calculating the cost effectiveness of interventions to prevent and treat obesity.

Project description:ObjectiveTo identify the characteristics of high-cost (HC) patients and the determinants of the annual medical expenditures of Chinese rural residents.MethodsMedical expenditure clustering was performed by Lorentz curve and Gini index. T and X2 tests were performed to identify the characteristics of the respondents, and a multilevel regression model examined the determinants of their annual medical expenditures.DesignA cluster sampling study was performed to identify those residents who availed healthcare services and to assign them to HC (top 5%), moderate-cost (top 30%) and low-cost (others) groups based on their annual medical expenditures.SettingThe annual healthcare utilisation was calculated by using data from the population-based database of the 2014 New Rural Cooperative Medical System.ParticipantsA total of 478 051 residents who availed healthcare services were recruited for the retrospective study in 2014. The annual medical expenditures of these residents were used as the research object.ResultsThe total medical expenditures of Macheng city residents for the year 2014 have a Gini index of 0.81 and around 68.01% of these expenditures can be attributed to HC patients. Female residents (51.5%) and persons aged over 60 years (34.48%) who are suffering from diseases that are difficult to diagnose have a high tendency to accumulate high medical costs. The annual medical expenditures of people living in the same village or town tend to be approximated. Age, disease category, inpatient status, healthcare utilisation and utilisation level are identified as the determinants of annual medical expenditures.ConclusionsThe medical expenditures of rural residents are clustered at a remarkably high level, and HC patients are suffering from high economic burden. Therefore, policy-makers must guide these patients in seeking appropriate healthcare services and improve their management of healthcare quality to reduce the unnecessary healthcare utilisation of these patients.Trial registration numberChiCTR-OOR-14005563.
