Objectives: This paper assesses the impact of effective access on out-of-pocket health payments and catastrophic health expenditure. Effective access cannot be attained unless both health services and financial risk protection are accessible, affordable, and acceptable. Therefore, it represents a key determinant in the transition from fragmented health systems to universal coverage that many low- and middle-income countries face.Methods: We use a definition of effective access as the utilization of health insurance when available. We conducted a cross-sectional analysis using the 2018 Mexican National Health Survey (ENSANUT) at the household level. The analysis is performed in two stages. The first stage is a multinomial analysis that captures the factor associated with choosing effective access against the alternative of paying privately. The second stage consists of an impact analysis regarding the decision of not choosing effective access in terms of out-of-pocket (OOP) health payments and catastrophic health expenditures (CHE). The analysis corrects for both the decision to buy insurance and the decision to pay for health care.Results: We found that, on average, not choosing effective access increases OOP health payments by around 2300 pesos annually. Medicine payments are the most common factor in this increase. Nevertheless, outpatient and medicines health care are the main drivers of the increase in OOP health payments in all insurance beneficiaries. Not having effective access increases the probability of CHE health expenditures by 2.7 p.p. for the case of Social Security Insurance and 4.0 p.p. for Social Government insurance. Household enrolled inProsperaprogram for the poor are more likely to choose effective access while having household heads with more education and assets value does the opposite. Diabetes illnesses are associated with a higher probability of effective access.Conclusion: Improving effective access is a middle step that cannot be disregarded when seeking universal coverage because OOP health payments and catastrophic outcomes are direct consequences. Public insurance in general, has around 50% effective access which remains a challenge in terms of health services utilization and health public policy design, calling for the need of better coordination across insurance types and pooling mechanisms to increase sustainability of needed health services.

Catastrophic out-of-pocket health expenditure (CHE) remain high in Sub-Saharan Africa and may not conform to the sporadic random pattern of acute illnesses that shapes insurance arrangements intended to avoid the risk of financial loss. The persistency of CHE remains a largely unexplored issue due to the lack of relevant methods and scarcity of panel data. This paper addresses the first shortcoming by presenting three different approaches to incorporating the timeframes into the analysis, considering dynamics between two periods, average over time and the recurrence of CHE incidence. Through the application of the complementary approaches, we identify (i) those at risk of persistent CHE in the short-term; (ii) those facing transient versus persistent CHE in the long-term; and (iii) those facing multiple CHE spells. The methods are applied to different definitions of CHE using panel data from three sub-Saharan countries: Malawi (3 waves: 2010, 2013, and 2016) with 4983 observations; Tanzania (3 waves: 2008, 2010, and 2012) with 8715 observations; and Uganda (5 waves: 2009, 2010, 2011, 2013, and 2015) with 6475 observations. All datasets are balanced panels. Additionally, we employ empirical strategies to identify the underlying factors contributing to these persistent and relatively high OOP. Across the three countries, we find that at least 27% of the people facing CHE in one period, because they spent more than 5% of their household budget on health out-of-pocket, will face it again in the next period. The lower-bound risk for those spending more than 10% of their household budget is 9% and for those spending more than 25% of their household capacity to pay is 13%. Between 11% and 45% of the population incurred CHE at least twice during the observation period when using the 5% budget definition of CHE. The double recurrence rate ranges between 7% and 13% when using the 25% capacity-to-pay definition and between 3% and 20% when using the 10% budgetshare definition. Between 22% and 32% of the population experienced chronic CHE at the 5% of the budgetshare definition (6%-10% at the 10% of the budgetshare definition of CHE; 2%-11% at 25% of capacity-to-pay). Our panel regression analysis consistently highlights the susceptibility of certain groups to face persistence CHE, notably those residing in rural areas, individuals with lower levels of education, the elderly, and those who have undergone hospitalizations.

Equity in health financing is a key concern of health systems worldwide, particularly segmented and fragmented ones [1,2]. Health systems must guarantee equitable access to effective and timely health services. However, accessing health services can lead to individuals, mainly those from vulnerable populations, using significant portions of their disposable income to pay privately and compromising […]

Background: Equitable health service utilization is key to health systems' optimal performance and universal health coverage. The evidence shows that men and women use health services differently. However, current analyses have failed to explore these differences in depth and investigate how such gender disparities vary by service type. This study examined the gender gap in the use of outpatient health services by Mexican adults with non-communicable diseases (NCDs) from 2006 to 2022. Methods: A cross-sectional population-based analysis of data drawn from National Health and Nutrition Surveys of 2006, 2011–12, 2020, 2021, and 2022 was performed. Information was gathered from 300,878 Mexican adults aged 20 years and older who either had some form of public health insurance or were uninsured. We assessed the use of outpatient health services provided by qualified personnel for adults who reported having experienced an NCD and seeking outpatient care in the 2 weeks before the survey. Outpatient service utilization was disaggregated into four categories: non-use, use of public health services from providers not corresponding to the user’s health insurance, use of public health services from providers not corresponding to the user’s health insurance, and use of private services. This study reported the mean percentages (with 95% confidence intervals [95% CIs]) for each sociodemographic covariate associated with service utilization, disaggregated by gender. The percentages were reported for each survey year, the entire study period, the types of service use, and the reasons for non-use, according to the type of health problem. The gender gap in health service utilization was calculated using predictive margins by gender, type of disease, and survey year, and adjusted through a multinomial logistic regression model. Results: Overall, we found that women were less likely to fall within the “non-use” category than men during the entire study period (21.8% vs. 27.8%, P < 0.001). However, when taking into account the estimated gender gap measured by incremental probability and comparing health needs caused by NCDs against other conditions, compared with women, men had a 7.4% lower incremental likelihood of falling within the non-use category ( P < 0.001), were 10.8% more likely to use services from providers corresponding to their health insurance ( P < 0.001), and showed a 12% lower incremental probability of using private services ( P < 0.001). Except for the gap in private service utilization, which tended to shrink, the others remained stable throughout the period analyzed. Conclusion: Over 16 years of outpatient service utilization by Mexican adults requiring care for NCDs has been characterized by the existence of gender inequalities. Women are more likely either not to receive care or resort to using private outpatient services, often resulting in catastrophic out-of-pocket expenses for them and their families. Such inequalities are exacerbated by the segmented structure of the Mexican health system, which provides health insurance conditional on formal employment participation. These findings should be considered as a key factor in reorienting NCD health policies and programs from a gender perspective.
