Objective

The aim of the study was to estimate the effect of the state-based reinsurance programs through the section 1332 State Innovation Waivers on health insurance marketplace premiums and insurer participation.

Data Source

2015 to 2022 Robert Wood Johnson Foundation Health Insurance Exchange Compare Datasets.

Study Design

An event study difference-in-differences (DD) model separately for each year of implementation and a synthetic control method (SCM) are used to estimate year-by-year effects following program implementation.

Data Collection/Extraction Methods

Not applicable.

Principal Findings

Reinsurance programs were associated with a decline in premiums in the first year of implementation by 10%–13%, 5%–19%, and 11%–17% for bronze, silver, and gold plans (p < 0.05). There is a trend of sustained declines especially for states that implemented their programs in 2019 and 2020. The SCM analyses suggest some effect heterogeneity across states but also premium declines across most states. There is no evidence that reinsurance programs affected insurer participation.

Conclusion

State-based reinsurance programs have the potential to improve the affordability of health insurance coverage. However, reinsurance programs do not appear to have had an effect on insurer participation, highlighting the need for policy makers to consider complementary strategies to encourage insurer participation.  相似文献

A comparative study of the financing, provision and quality of care in nursing homes. The approach of four European countries: Belgium, Denmark, Germany and the Netherlands As result of an increase in the numbers of frail elderly people, most European countries are facing problems with the financing and provision of services by nursing homes. At the same time, the expectations of quality of these services continue to rise. The main question investigated in this study was that of how countries approach the problems of financing and service provision by nursing homes and, at the same time, attempt to increase the quality levels in these institutions. The study was conducted in Belgium, Denmark, Germany and the Netherlands. A study was made of the relevant literature and questionnaires were sent to experts in each country. The four countries are addressing the problems of financing and sufficient service provision by controlling the use of nursing home services. In addition, financial problems are approached by extending co-payments, encouraging cheaper forms of care and putting pressure on nursing homes to operate at lower costs. Problems in the provision of care are addressed by applying more selective admission criteria and offering alternative forms of care outside the nursing home. As a result nursing home beds are used for those with the greatest care-dependency. Nursing home services are adjusted to rising quality expectations by offering a greater range of provision, decreasing the number of residents per room, improving comfort and improving the training of nursing staff. Another way to increase the quality of care is to separate the housing and service functions. Many nursing homes nowadays collaborate intensively with other facilities for the elderly to cope with all these problems and changes. The workload for nursing home staff has increased because of the increasing care-dependency of residents, the demand for higher quality of services and the financial problems.  相似文献

Background

Health has improved markedly in Mesoamerica, the region consisting of southern Mexico and Central America, over the past decade. Despite this progress, there remain substantial inequalities in health outcomes, access, and quality of medical care between and within countries. Poor, indigenous, and rural populations have considerably worse health indicators than national or regional averages. In an effort to address these health inequalities, the Salud Mesoamérica 2015 Initiative (SM2015), a results-based financing initiative, was established.

Methods

For each of the eight participating countries, health targets were set to measure the progress of improvements in maternal and child health produced by the Initiative. To establish a baseline, we conducted censuses of 90,000 households, completed 20,225 household interviews, and surveyed 479 health facilities in the poorest areas of Mesoamerica. Pairing health facility and household surveys allows us to link barriers to care and health outcomes with health system infrastructure components and quality of health services.

Results

Indicators varied significantly within and between countries. Anemia was most prevalent in Panama and least prevalent in Honduras. Anemia varied by age, with the highest levels observed among children aged 0 to 11 months in all settings. Belize had the highest proportion of institutional deliveries (99%), while Guatemala had the lowest (24%). The proportion of women with four antenatal care visits with a skilled attendant was highest in El Salvador (90%) and the lowest in Guatemala (20%). Availability of contraceptives also varied. The availability of condoms ranged from 83% in Nicaragua to 97% in Honduras. Oral contraceptive pills and injectable contraceptives were available in just 75% of facilities in Panama. IUDs were observed in only 21.5% of facilities surveyed in El Salvador.

Conclusions

These data provide a baseline of much-needed information for evidence-based action on health throughout Mesoamerica. Our baseline estimates reflect large disparities in health indicators within and between countries and will facilitate the evaluation of interventions and investments deployed in the region over the next three to five years. SM2015’s innovative monitoring and evaluation framework will allow health officials with limited resources to identify and target areas of greatest need.

Nigeria faces challenges that delay progress toward the attainment of the national government''s declared goal of universal health coverage (UHC). One such challenge is system-wide inequities resulting from lack of financial protection for the health care needs of the vast majority of Nigerians. Only a small proportion of Nigerians have prepaid health care. In this paper, we draw on existing evidence to suggest steps toward reforming health care financing in Nigeria to achieve UHC through social health insurance. This article sets out to demonstrate that a viable path to UHC through expanding social health insurance exists in Nigeria. We argue that encouraging the states which are semi-autonomous federating units to setup and manage their own insurance schemes presents a unique opportunity for rapidly scaling up prepaid coverage for Nigerians. We show that Nigeria''s federal structure which prescribes a sharing of responsibilities for health care among the three tiers of government presents serious challenges for significantly extending social insurance to uncovered groups. We recommend that rather than allowing this governance structure to impair progress toward UHC, it should be leveraged to accelerate the process by supporting the states to establish and manage their own insurance funds while encouraging integration with the National Health Insurance Scheme.  相似文献
