Does voluntary health insurance improve health and longevity? Evidence from European OECD countries

Country-level effects of diagnosis-related groups: evidence from Germany's comprehensive reform of hospital payments

Hospitals account for about 40% of all healthcare expenditure in high-income countries and play a central role in healthcare provision. The ways in which they are paid, therefore, has major implications for the care they provide. However, our knowledge about reforms that have been made to the various payment schemes and their country-level effects is surprisingly thin. This study examined the uniquely comprehensive introduction of diagnosis-related groups (DRGs) in Germany, where DRGs function as the sole pricing, billing, and budgeting system for hospitals and almost exclusively determine hospital revenue. The introduction of DRGs, therefore, completely overhauled the previous system based on per diem rates, offering a unique opportunity for analysis. Using aggregate data from the Organisation for Economic Co-operation and Development and recent advances in econometrics, we analyzed how hospital activity and efficiency changed in response to the reform. We found that DRGs in Germany significantly increased hospital activity by around 20%. In contrast to earlier studies, we found that DRGs have not necessarily shortened the average length of stay.

Determinants of life-expectancy and disability-adjusted life years (DALYs) in European and Organisation for Economic Co-operation and Development (OECD) countries: A longitudinal analysis (1990-2019)

•We relate 68 factors to population health observed in 61 countries over 30 years.•Using random forests, multiple imputation and generalized estimating equations.•GDP per capita and demographics are key; income inequality is not.•Health and social expenditure are more influential than freedom and corruption.•On the macro-level, life-style effects appear to be mediated by cultural context.

Pediatric Health Access and Private Medical Insurance: Based on the Ecology of Medical Care in Korea

This study aimed to investigate pediatric health access by describing the ecology of medical care for children and adolescents in a medical environment where a well-balanced system between national health insurance (NHI) and private medical insurance (PMI) is required. Data from 2746 individuals aged 18 years old and younger were used. Of the participants, 87.3% had private medical insurance. Of the 1000 children, in an average month, 404 visited a clinic, 67 visited a hospital outpatient department (OPD), 49 visited an OPD in a tertiary hospital, 11 received emergency care, 5 received inpatient care in a hospital, and 9 were hospitalized. The generalized estimating equation models adjusted for age, sex, economic status, and pediatric comorbidity index were used for multivariate analysis. Receiving ambulatory care services in clinics was significantly more likely among children and adolescents with private medical insurance (adjusted odds ratio [aOR] = 1.16 [95% confidence interval [CI]: 1.00-1.35]). Receiving ambulatory care services in clinics was significantly more likely among indemnity type policyholders (aOR = 1.23 [1.05-1.45]) and single policyholders (aOR = 1.18 [1.00-1.37]). Countries with national health insurance schemes should continuously practice the proper regulation and management of PMI, including reviewing PMI compensation measures, NHI reimbursement standards, and consumers' perspectives on NHI and PMI.
