Improving the effective maternal-child health care coverage through synergies between supply and demand-side interventions: evidence from Mexico

COVID-19 and the adequacy of antenatal care among Indigenous women: A retrospective crossover analysis

BACKGROUND

Often marginalized and disadvantaged by systems of oppression, Indigenous populations commonly face significant barriers to accessing adequate antenatal care (ANC). The COVID-19 pandemic had an unprecedented impact on healthcare systems worldwide, including on the provision of antenatal care; this was especially so for Indigenous communities in many regions. As such, our study aimed to estimate the association between the COVID-19 pandemic and adequate ANC received by Indigenous women in Chiapas, Mexico.

METHODS

We conducted a retrospective crossover analysis with data collected between June and December 2021 from Indigenous women who attended at least one ANC appointment at one of two health centers in San Cristóbal de las Casas, Chiapas. We used a multinomial logistic regression model considering the time frame (before and during the pandemic) as the primary independent variable. Adequate antenatal care comprised four dimensions: attendance by qualified personnel, timely first visit, sufficient frequency of visits, and adequacy of the content provided during the visits.

RESULTS

During the COVID-19 pandemic, there was a significant drop in ANC adequacy, with 12.7% (95% CI: 8.3, 18.9) of Indigenous women receiving ANC, compared with the pre-pandemic rate of 52.5% (95% CI: 44.7, 60.3), among the 158 participants. The pandemic resulted in a reduction of 75.8% in the adequacy of ANC. Considering the four dimensions of adequacy, we found that having only one dimension was associated with a relative risk ratio (RRR) of 12.45 (95% CI: 6.40, 24.23), while having two or three dimensions was associated with a RRR of 5.23 (95% CI: 2.83, 9.65) when using adequate ANC as the category of reference.

CONCLUSIONS

According to our results, Indigenous women's ANC adequacy was negatively affected by the COVID-19 pandemic. In light of these findings, we emphasize the importance of developing healthcare systems that are prepared to adapt consultation schemes by implementing virtual visits and incorporating community health workers.

Persistent inequities in maternal mortality in Latin America and the Caribbean, 1990-2019

BACKGROUND

Despite the resources and personnel mobilized in Latin America and the Caribbean to reduce the maternal mortality ratio (MMR, maternal deaths per 100 000 live births) in women aged 10-54 years by 75% between 2000 and 2015, the region failed to meet the Millenium Development Goals (MDGs) due to persistent barriers to access quality reproductive, maternal, and neonatal health services.

METHODS

Using 1990-2019 data from the Global Burden of Disease project, we carried out a two-stepwise analysis to (a) identify the differences in the MMR temporal patterns and (b) assess its relationship with selected indicators: government health expenditure (GHE), the GHE as percentage of gross domestic product (GDP), the availability of human resources for health (HRH), the coverage of effective interventions to reduce maternal mortality, and the level of economic development of each country.

FINDINGS

In the descriptive analysis, we observed a heterogeneous overall reduction of MMR in the region between 1990 and 2019 and heterogeneous overall increases in the GHE, GHE/GDP, and HRH availability. The correlation analysis showed a close, negative, and dependent association of the economic development level between the MMR and GHE per capita, the percentage of GHE to GDP, the availability of HRH, and the coverage of SBA. We observed the lowest MMRs when GHE as a percentage of GDP was close to 3% or about US$400 GHE per capita, HRH availability of 6 doctors, nurses, and midwives per 1,000 inhabitants, and skilled birth attendance levels above 90%.

CONCLUSIONS

Within the framework of the Sustainable Development Goals (SDGs) agenda, health policies aimed at the effective reduction of maternal mortality should consider allocating more resources as a necessary but not sufficient condition to achieve the goals and should prioritize the implementation of new forms of care with a gender and rights approach, as well as strengthening actions focused on vulnerable groups.

Equity in out-of-pocket health expenditure: Evidence from a health insurance program reform in Mexico

Background

The fragmentation of health systems in low- and middle-income countries (LMICs) deepens health inequities and shifts the economic burden of health care to families via out-of-pocket spending (OOPHE). This problem has been addressed by introducing public health insurance programs for poor people; however, there is a lack of knowledge about how equitable these programs are. We aimed to analyse the long-term effects of the Seguro Popular (SP) voluntary health insurance program, recently phased out and replaced by the Health Institute for Welfare (Instituto de Salud para el Bienestar (INSABI)), on OOPHE equity in the poor Mexican population.

Methods

We conducted a pooled cross-sectional analysis using eleven waves of the National Household Income and Expenditure Survey (2002-2020). We identified the effect of SP by selecting households without social security (with SP or without health insurance (n = 169 766)) and matched them by propensity score to reduce bias in the decision to enrol in SP. We estimated horizontal and vertical equity metrics and assessed their evolution across subpopulations.

Results

The program's entry years (2003-2010) show a positive redistributive effect associated with a focalised stage of the program, while oversaturation could have diluted these effects during 2010-2014, with adverse results in terms of vertical equity and re-ranking among insured families. SP is more horizontally inequitable than for those uninsured. Within SP, the redistributive effect could improve up to 13% if all families with similar expenditures were spending equal OOPHE and horizontal equity was eliminated. Regarding vertical equity, SP outperforms the insured population with middle-range coverage some years after the implementation, but this progress disappears.

Conclusions

To achieve universal health coverage, health authorities need to create and execute financial protection mechanisms that effectively address structural inequalities. This involves implementing a more comprehensive risk-pooling mechanism that makes social insurance sustainable in the long-run by increasing the social-economic influx of resources. It is essential to monitor oversaturation and financial sustainability to achieve optimal results. The replacement of the SP with INSABI highlights the complexity of maintaining a social insurance program where the ideology of different governments can influence the program structure, regulation, financing, and even its existence.

Inequitable Financial Protection in Health for Indigenous Populations: the Mexican Case

BACKGROUND

There is an important gap in the literature concerning the level, inequality, and evolution of financial protection for indigenous (IH) and non-indigenous (NIH) households in low- and middle-income countries. This paper offers an assessment of the level, socioeconomic inequality and middle-term trends of catastrophic (CHE), impoverishing (IHE), and excessive (EHE) health expenditures in Mexican IHs and NIHs during the period 2008-2020.

METHODS

We conducted a pooled cross-sectional analysis using the last seven waves of the National Household Income and Expenditure Survey (n = 315,829 households). We assessed socioeconomic inequality in CHE, IHE, and EHE by estimating their Wagstaff concentration indices according to indigenous status. We adjusted the CHE, IHE, and EHE by estimating a maximum-likelihood two-stage probit model with robust standard errors.

RESULTS

We observed that, during the period analyzed, CHE, IHE, and EHE were concentrated in the poorest IHs. CHE decreased from 5.4% vs. 4.7% in 2008 to 3.4% vs. 2.9% in 2014 in IHs and NIHs, respectively, and converged at 2008 levels towards 2020. IHE remained unchanged from 2008 to 2014 (1.6% for IHs vs. 1.0% for NIHs) and increased by 40% in IHs and NIHs during 2016-2020. EHE plunged in 2014 (4.6% in IHs vs. 3.8% in NIHs), then rose, and remained unchanged during 2016-2020 (6.7% in IHs and 5.6% in NIHs).

CONCLUSION

In pursuit of universal health coverage, health authorities should formulate and implement effective financial protection mechanisms to address structural inequalities, especially forms of discrimination including racialization, that vulnerable social groups such as indigenous peoples have systematically faced. Doing so would contribute to closing the persistent ethnic gaps in health.

Setbacks in the quest for universal health coverage in Mexico: polarised politics, policy upheaval, and pandemic disruption

2023 marks the 20-year anniversary of the creation of Mexico's System of Social Protection for Health and the Seguro Popular, a model for the global quest to achieve universal health coverage through health system reform. We analyse the success and challenges after 2012, the consequences of reform ageing, and the unique coincidence of systemic reorganisation during the COVID-19 pandemic to identify strategies for health system disaster preparedness. We document that population health and financial protection improved as the Seguro Popular aged, despite erosion of the budget and absent needed reforms. The Seguro Popular closed in January, 2020, and Mexico embarked on a complex, extensive health system reorganisation. We posit that dismantling the Seguro Popular while trying to establish a new programme in 2020-21 made the Mexican health system more vulnerable in the worst pandemic period and shows the precariousness of evidence-based policy making to political polarisation and populism. Reforms should be designed to be flexible yet insulated from political volatility and constructed and managed to be structurally permeable and adaptable to new evidence to face changing health needs. Simultaneously, health systems should be grounded to withstand systemic shocks of politics and natural disasters.

Effects of women's economic empowerment interventions on antenatal care outcomes: a systematic review

OBJECTIVES

Early and adequate antenatal care (ANC) has been shown to reduce maternal morbidity and mortality globally. Increasing evidence suggests that women's economic empowerment (WEE) is a critical factor that may influence uptake of ANC during pregnancy. However, existing literature lacks a comprehensive synthesis of studies on WEE interventions and their effects on ANC outcomes. This systematic review analyses WEE interventions at the household, community and national levels and their effects on ANC outcomes in low-income and middle-income countries, where the majority of maternal deaths occur.

METHODS

Six electronic databases were systematically searched as well as 19 websites of relevant organisations. Studies published in English and after 2010 were included.

RESULTS

Following abstract and full-text review, 37 studies were included in this review. Seven studies used an experimental study design, 26 studies used a quasi-experimental study design, 1 study used an observational design and 1 study was a systematic review with meta-analysis. Thirty-one included studies evaluated a household-level intervention, and six studies evaluated a community-level intervention. No included studies examined a national-level intervention.

CONCLUSION

Most included studies on household-level and community-level interventions found a positive association between the intervention and the number of ANC visits women received. This review emphasises the need for more WEE interventions that empower women at the national level, for the expansion of the definition of WEE to be more inclusive of the multidimensionality of WEE interventions and the social determinants of health, and the standardisation of ANC outcome measurement globally.

Evaluations of effective coverage of maternal and child health services: A systematic review

Conventionally used coverage measures do not reflect the quality of care. Effective coverage (EC) assesses the extent to which health care services deliver potential health gains to the population by integrating concepts of utilization, need and quality. We aimed to conduct a systematic review of studies evaluating EC of maternal and child health services, quality measurement strategies and disparities across wealth quantiles. A systematic search was performed in six electronic databases [MEDLINE, EMBASE, Cumulative Index of Nursing and Allied Health (CINAHL), Scopus, Web of Science and Maternity and Infant Care] and grey literature. We also undertook a hand search of references. We developed search terms having no restrictions based on publication period, country or language. We included studies which reported EC estimates based on the World Health Organization framework of measuring EC. Twenty-seven studies, all from low- and middle-income settings (49 countries), met the criteria and were included in the narrative synthesis of the results. Maternal and child health intervention(s) and programme(s) were assessed either at an individual level or as an aggregated measure of health system performance or both. The EC ranged from 0% for post-partum care to 95% for breastfeeding. When crude coverage measures were adjusted to account for the quality of care, the EC values turned lower. The gap between crude coverage and EC was as high as 86%, and it signified a low quality of care. The assessment of the quality of care addressed structural, process and outcome domains individually or combined. The wealthiest 20% had higher EC of services than the poorest 20%, an inequitable distribution of coverage. More efforts are needed to improve the quality of maternal and child health services and to eliminate the disparities. Moreover, considering multiple dimensions of quality and the use of standard measurements are recommended to monitor coverage effectively.

Public health insurance and ethnic disparities in maternal health care: the case of vulnerable Mexican women over the last 25 years

This article examines the coverage in the continuum of antenatal-postnatal care for vulnerable women in Mexico according to indigenous status and assesses the influence of public health insurance strategies on the evolution of coverage over the last 25 years. We studied a total of 19 613 567 Mexican women, aged 12-54 years at last birth, based on a pooled cross-sectional analysis of data from the 1997, 2009, 2014 and 2018 waves of the National Survey of Demographic Dynamics. After describing sociodemographic characteristics and maternal-health coverage by indigenous status, we constructed a pooled fixed-effects and interaction multivariable regression model to assess the influence of the Seguro Popular programme on continuum of care. We estimated adjusted continuum of care coverage between 1994 and 2018 according to Seguro Popular affiliation and indigenous status. Prior to the Seguro Popular programme, crude coverage in the continuum of care for non-indigenous women stood at 14.5% [95% confidence interval (CI): 13.2-15.8%] or 11 percentage points higher than for indigenous women. During the last period of the programme, it rose to 46.5% [95% CI: 45.6-47.5%] and 34.1% [95% CI: 30.7-37.4%], respectively. Our regression analysis corroborated findings that, on average, indigenous women faced lower odds of benefiting from continuum of care [adjusted odds ratio (aOR) = 0.48, 95% CI: 0.40-0.57] than did their non-indigenous counterparts. It also revealed that coverage for indigenous women without Seguro Popular affiliation was 26.7% [95% CI: 23.3-30.1%] or 12 percentage points lower than for those with Seguro Popular affiliation (38.6%, 95% CI: 35.7-41.4%). Our regression results confirmed that the latter benefited from higher odds of continuum of care (aOR = 1.67, 95% CI: 1.36-2.26). Gaps between those of indigenous and non-indigenous status have persisted, but the Seguro Popular clearly contributed to reducing the coverage gaps between these two groups of women. Strategies yielding better outcomes are required to improve the structural conditions of indigenous populations.

Assessing the continuum of care for maternal health in Mexico, 1994-2018

OBJECTIVE

To describe the temporal and geographical patterns of the continuum of maternal health care in Mexico, as well as the sociodemographic characteristics that affect the likelihood of receiving this care.

METHODS

We conducted a pooled cross-sectional analysis using the 1997, 2009, 2014 and 2018 waves of the National Survey of Demographic Dynamics, collating sociodemographic and obstetric characteristics of 93 745 women aged 12-54 years at last delivery. We defined eight variables along the antenatal-postnatal continuum, both independently and conditionally. We used a pooled fixed-effects multivariable logistic model to determine the likelihood of receiving the continuum of care for various properties. We also mapped the quintiles of adjusted state-level absolute change in continuum of care coverage during 1994-2018.

FINDINGS

We observed large absolute increases in the proportion of women receiving timely antenatal and postnatal care (from 48.9% to 88.2% and from 39.1% to 68.7%, respectively). In our conditional analysis, we found that the proportion of women receiving adequate antenatal care doubled over this period. We showed that having social security and a higher level of education is positively associated with receiving the continuum of care. We observed the largest relative increases in continuum of care coverage in Chiapas (181.5%) and Durango (160.6%), assigned human development index categories of low and medium, respectively.

CONCLUSION

Despite significant progress in coverage of the continuum of maternal health care, disparities remain. While ensuring progress towards achievement of the health-related sustainable development goal, government intervention must also target underserved populations.
