Reinterpreting Medical Innovation: The Social Adoption of Automated Multiphasic Health Testing and Services in Japan, 1937–2023

The dynamics of health care delivery for children and adolescents have greatly evolved over the last 5 years. The growth of managed care has been especially rapid, and has coincided with other fundamental changes—declines in private coverage, growth of Medicaid, welfare reform, and the creation of the state Child Health Insurance Program (CHIP).1 Over the past 10 years, the number of children covered through employer-sponsored plans and other private plans has dropped.2 During this same period, changes to Medicaid have begun to de-couple eligibility from welfare eligibility, theoretically enabling states to expand coverage. For children, this movement from private to public coverage has accelerated the movement to managed care systems. Between 1991 and 1997, Medicaid enrollment in managed care plans increased from 9.5% to 47.8% of total Medicaid enrollment.3 Recent estimates suggest that over half of these Medicaid managed care enrollees are children.4 However, little is known about the impact of these trends on children's access to and use of services, let alone the quality and outcomes of that care. This report is the first in what is anticipated to be an annual series of reports on access to and use of health care services by America's children and youth. The report capitalizes on the existence of 2 national datasets, the Medical Expenditure Panel Survey (MEPS) and the Healthcare Cost and Utilization Project (HCUP), which have not been widely used by the child health services research community. As background to these new sources of data, we have provided a detailed description of the datasets, and review some of the fundamental tabulations. In future years, as more data are accumulated, these reports will focus on delineation of key trends and analyses addressing policy issues. ### MEPS The MEPS is conducted to provide nationally representative estimates of health care use, …

Most health-care services in Japan are provided through the public health insurance system. Japan enjoys the lowest infant mortality rate and the longest life expectancy in the world. This chapter describes the historical development of the public health-care system and evaluates problems up to the present day. It then discusses current and future reforms from a financial perspective. Japan's public health insurance for private sector employees was introduced by the Health Insurance Law of 1922. The health insurance system faced a financial crisis shortly after its establishment in 1929 resulting from the global Great Depression, but it gradually regained financial stability as the nation's economy started to grow again. Universal health care coverage through a public health insurance scheme with fee-for-service payment is the basic definition of the Japanese system, which has contributed to the equitable distribution of health services and relieved families from old-age support.

Who Is Paying the Price? Loss of Health Insurance Coverage Early in Psychosis

We estimate the impact of a differential treatment of paid employees versus self-employed workers in a public health insurance system on the entry rate into entrepreneurship. In Germany, the public health insurance system is mandatory for most paid employees, but not for the self-employed, who usually buy private health insurance. Private health insurance contributions are relatively low for the young and healthy, and until 2013 also for males, but less attractive at the other ends of these dimensions and if membership in the public health insurance system allows other family members to be covered by contribution-free family insurance. Therefore, the health insurance system can create incentives or disincentives to starting up a business depending on the family’s situation and health. We estimate a discrete time hazard rate model of entrepreneurial entry based on representative household panel data for Germany, which include personal health information, and we account for non-random sample selection. We estimate that an increase in the health insurance cost differential between self-employed workers and paid employees by 100 euro per month decreases the annual probability of entry into self-employment by 0.38 percentage points, i.e. about a third of the average annual entry rate. The results show that the phenomenon of entrepreneurship lock, which an emerging literature describes for the system of employer provided health insurance in the USA, can also occur in a public health insurance system. Therefore, entrepreneurial activity should be taken into account when discussing potential health care reforms, not only in the USA and in Germany.

Whether an individual can or cannot participate in the Czech public health insurance system depends on several characteristics, one of which is whether he/she has permanent residence status in the Czech Republic, and a second whether he/she is employed. This means that those without permanent residence status, including self-employed migrants from third countries, their dependent relatives, and the dependent relatives of third country employees in the Czech Republic, cannot participate in the public health insurance system. Some argue that such migrants should be included in the system, since commercial health insurance is disadvantageous and the contributions they would pay into the public health insurance system would increase the public health insurance agencies’ income. We estimate the value of the contributions to public health insurance that would be paid by third country self-employed and non-working immigrants, if they were insured based on data from 2011 to 2013, and compare this to the assumed costs of their medical care. To calculate the contributions for self-employed migrants we use data on the distribution of the tax base for self-employed persons from personal income tax returns. Our estimation results in an overall negative balance of 22 million CZK on the data for 2012 and 2013. In the current system this deficit would be covered by the state, which would pay contributions to the system for certain (state insured) persons amounting to 97 million CZK; overall therefore the inclusion of these immigrants would result in a positive balance of 75 million CZK.

Do Canada and the United States Differ in Prevalence of Depression and Utilization of Services?

This paper documents the changing picture of health insurance coverage for pregnant women in the four-year period following Medicaid expansion and assesses the extent to which the crowding-out phenomenon may have influenced the observed trends. The report documents the distribution of insurance coverage for pregnant women in the post-expansion period and describes demographic characteristics of women covered under Medicaid. It examines the rate at which Medicaid-eligible women enroll in the program and addresses the crowding-out issue by comparing the trend in employer-sponsored coverage among poor and near-poor pregnant women with those among nonpregnant women and men of similar ages and incomes.

This study estimated the rates of health insurance coverage in the U.S. civilian noninstitutionalized population with schizophrenia and assessed whether basic access to health care varied across health insurance categories. Data from the Medical Expenditures Panel Survey collected between 2002 and 2006 were used. The sample contained 328 records representing 493,006 noninstitutionalized civilian persons with schizophrenia. Eighty-seven percent had Medicaid or Medicare, 8% received care through the Veterans Health Administration, and 15% had private insurance for at least one day during the year. About 7% were uninsured all of the year. The uninsured tended to be male (92%), nonwhite (54%), and unmarried (97%), and 30% of the uninsured had not had a medical checkup in more than five years. Almost all U.S. adults with schizophrenia were found to receive government health insurance, yet a measurable minority remained uninsured. These national estimates highlight opportunities for improving health service delivery for this vulnerable population.

Children without Health Insurance

The Czech government has identified commercial health insurance as one of the major problems for migrants’ access to health care. Non-EU immigrants are eligible for public health insurance only if they have employee status or permanent residency. The present study examined migrants’ access to the public health insurance system in Czechia. A cross-sectional survey of 909 immigrants from Ukraine and Vietnam was conducted in March and May 2013, and binary logistic regression was applied in data analysis. Among immigrants entitled to Czech public health insurance due to permanent residency/asylum, 30% were out of the public health insurance system, and of those entitled by their employment status, 50% were out of the system. Migrants with a poor knowledge of the Czech language are more likely to remain excluded from the system of public health insurance. Instead, they either remain in the commercial health insurance system or they simultaneously pay for both commercial and public health insurance, which is highly disadvantageous. Since there are no reasonable grounds to stay outside the public health insurance, it is concluded that it is lack of awareness that keeps eligible immigrants from entering the system. It is suggested that no equal access to health care exists without sufficient awareness about health care system.

We investigate the impact of a differential treatment of paid employees versus self-employed workers in a public health insurance system on the entry rate into self-employment. Health insurance systems that distinguish between the two sectors of employment create incentives or disincentives to start a business for different individuals. We estimate a discrete time hazard rate model of entry into self-employment based on representative household panel data for Germany, which include individual health information. The results indicate that an increase in the health insurance cost differential between self-employed workers and paid employees by €10 per month decreases the probability of entry into self-employment by 1.7% of the annual entry rate. This shows that entrepreneurship lock, which an emerging literature describes for the system of employer-provided health insurance in the USA, can also occur in a public health insurance system. Therefore, entrepreneurial activity should be taken into account when discussing potential health-care reforms.

Although the Chinese government has established a public health insurance system covering both rural and urban areas, the rural–urban migrants seem to have been neglected. To have a clear sense of the current status of migrants in the public health insurance system and to find ways to increase their enrollment to medical insurance, this paper attempts to construct a conceptual classification framework of China’s health insurance system. This was done by reviewing the development of China’s health insurance system and identifying barriers to entry for migrants. The finding suggests that migrants’ limited access to health insurance owes more to their reluctance than to system exclusions. The job and residential stability of migrants are critical factors to building the classification framework to account for supply and demand factors in the formulation of China’s health insurance policy.
