Background: The determinants of access to immunizers are still poorly understood, leading to questions about which criteria were considered in this distribution. Given the above, the present study aimed to analyze the determinants of access to the SARS-CoV-2 vaccine by different countries. Methods: The study covered 189 countries using data from different public databases, and collected until February 19, 2021. We used eight explanatory variables: gross domestic product (GDP), extreme poverty, human development index (HDI), life expectancy, median age, coronavirus disease 2019 (COVID-19) cases, COVID-19 tests, and COVID-19 deaths. The endogenous variables were total vaccine doses, vaccine doses per thousand, and days of vaccination. The structural equation modeling (SEM) technique was applied to establish the causal relationship between the country's COVID-19 impact, socioeconomic variables, and vaccine access. To support SEM, we used confirmatory factor analysis, t-test, and Pearson's correlation. Results: We collected the sample on February 19, and to date, 80 countries (42.1%) had already received a batch of immunizers against COVID-19. The countries with first access to the vaccine (e.g., number of days elapsed since they took the first dose) were the United Kingdom (68), China (68), Russia (66), and Israel (62). The countries receiving the highest doses were the United States, China, India, and Israel. The countries with extreme poverty had lower access to vaccines and the richer countries gained priority access. Countries most affected by COVID (deaths and cases) also received immunizers earlier and in greater volumes. Unfortunately, similar to other vaccines, indicators, such as income, poverty, and human development, influence vaccines' access. Thus affecting the population of vulnerable and less protected countries. Therefore, global initiatives for the equitable distribution of COVID need to be discussed and encouraged. Conclusions: Determinants of vaccine distribution consider the impact of the disease in the country and are also affected by favorable socioeconomic indicators. The COVID-19 vaccines need to be accessible to all affected countries, regardless of their social hands. [ABSTRACT FROM AUTHOR]

Background: Improving health equity is a fundamental goal for establishing social health insurance. This article evaluated the benefits of the Integration of Social Medical Insurance (ISMI) policy for health services utilization in rural China. Methods: Using the China Health and Retirement Longitudinal study (2011‒2018), we estimated the changes in rates and equity in health services utilization by a generalized linear mixed model, concentration curves, concentration indices, and a horizontal inequity index before and after the introduction of the ISMI policy. Results: For the changes in rates, the generalized linear mixed model showed that the rate of inpatient health services utilization (IHSU) nearly doubled after the introduction of the ISMI policy (8.78 % vs. 16.58 %), while the rate of outpatient health services utilization (OHSU) decreased (20.25 % vs. 16.35 %) after the implementation of the policy. For the changes in inequity, the concentration index of OHSU decreased significantly from − 0.0636 (95 % CL: −0.0846, − 0.0430) before the policy to − 0.0457 (95 % CL: −0.0684, − 0.0229) after it. In addition, the horizontal inequity index decreased from − 0.0284 before the implementation of the policy to − 0.0171 after it, indicating that the inequity of OHSU was further reduced. The concentration index of IHSU increased significantly from − 0.0532 (95 % CL: −0.0868, − 0.0196) before the policy was implemented to − 0.1105 (95 % CL: −0.1333, − 0.0876) afterwards; the horizontal inequity index of IHSU increased from − 0.0066 before policy implementation to − 0.0595 afterwards, indicating that more low-income participants utilized inpatient services after the policy came into effect. Conclusions: The ISMI policy had a positive effect on improving the rate of IHSU but not on the rate of OHSU. This is in line with this policy's original intention of focusing on inpatient service rather than outpatients to achieve its principal goal of preventing catastrophic health expenditure. The ISMI policy had a positive effect on reducing the inequity in OHSU but a negative effect on the decrease in inequity in IHSU. Further research is needed to verify this change. This research on the effects of integration policy implementation may be useful to policy makers and has important policy implications for other developing countries facing similar challenges on the road to universal health coverage.

Background: Health expenditure for tuberculosis (TB) care often pushes households into catastrophe and poverty. New Cooperative Medical Scheme (NCMS) aims to protect households from catastrophic health expenditure (CHE) and impoverishment in rural China. This article assesses the effect of NCMS on relieving CHE and impoverishment from TB care in rural China. Methods: Three hundred fourty-seven TB cases are included in the analysis. We analyze the incidence and intensity of CHE and poverty, and assess the protective effect of NCMS by comparing the CHE and impoverishment before and after reimbursement. Results: After out-of-pocket (OOP) payment for TB care, 16.1 % of non-poor fall below poverty line. The NCMS reduces the incidence of CHE and impoverishment by 11.5 % and 7.3 %. After reimbursement, 46.7 % of the households still experience CHE and 35.4 % are below the poverty line. The NCMS relieves the mean gap, mean positive gap, poverty gap and normalized positive gap by 44.5 %, 51.0 %, US$115.8 and 31.6 % respectively. Conclusions: The NCMS has partial effect on protecting households from CHE and impoverishment from TB care. The limited protection could be enhanced by redesigning benefit coverage to improve the "height" of the NCMS and representing fee-for-service with alternative payment mechanisms.

Background: China poverty reduction policy (PRP) addresses two important elements: the targeted poverty reduction (TPA) project since 2015 in line with social assistance policy as national policy; and reducing inequality in health services utilization by making provision of medical financial assistance (MFA). Therefore, this study aims to assess the effects of the PRP in health services utilization (both inpatient and outpatient services) among the central and western rural poor of China. Methods: The study conducted household survey and applied propensity score matching (PSM) method to assess the effects of the PRP on health services utilization among the rural poor of Central and Western China. A sensitivity test was also performed on the PSM results to test their robustness. Results: Key findings showed 17.6% of respondents were the beneficial of PRP. The average treatment effects on the treated (ATT) of the PRP on the inpatient visits within one year was found significantly positive (P = 0.026). Conclusion: There has been relationship between PRP with medical financial assistance and reduction of inequality in health services utilization by the poorer, in particular to accessing the inpatient services from the county or township hospitals of China. Policy makers should pay attention for making provision of improving responsiveness of supply, when subsidizing on the demand side. [ABSTRACT FROM AUTHOR]
