Utilization of services provided by village based ethnic minority midwives in mountainous villages of Vietnam

Protocol for a realist synthesis of health systems responsiveness in low-income and middle-income countries

INTRODUCTION

Health systems responsiveness is a key objective of any health system, yet it is the least studied of all objectives particularly in low-income and middle-income countries. Research on health systems responsiveness highlights its multiple elements, for example, dignity and confidentiality. Little is known, however, about underlying theories of health systems responsiveness, and the mechanisms through which responsiveness works. This realist synthesis contributes to bridging these two knowledge gaps.

METHODS AND ANALYSIS

In this realist synthesis, we will use a four-step process, comprising: mapping of theoretical bases, formulation of programme theories, theory refinement and testing of programme theories using literature and empirical data from Ghana and Vietnam. We will include theoretical and conceptual pieces, reviews, empirical studies and grey literature, alongside the primary data. We will explore responsiveness as entailing external and internal interactions within health systems. The search strategy will be purposive and iterative, with continuous screening and refinement of theories. Data extraction will be combined with quality appraisal, using appropriate tools. Each fragment of evidence will be appraised as it is being extracted, for its relevance to the emerging programme theories and methodological rigour. The extracted data pertaining to contexts, mechanisms and outcomes will be synthesised to identify patterns and contradictions. Results will be reported using narrative explanations, following established guidance on realist syntheses.

Realist evaluation to improve health systems responsiveness to neglected health needs of vulnerable groups in Ghana and Vietnam: Study protocol

BACKGROUND

Socio-economic growth in many low and middle-income countries has resulted in more available, though not equitably accessible, healthcare. Such growth has also increased demands from citizens for their health systems to be more responsive to their needs. This paper shares a protocol for the RESPONSE study which aims to understand, co-produce, implement and evaluate context-sensitive interventions to improve health systems responsiveness to health needs of vulnerable groups in Ghana and Vietnam.

METHODS

We will use a realist mixed-methods theory-driven case study design, combining quantitative (household survey, secondary analysis of facility data) and qualitative (in-depth interviews, focus groups, observations and document and literature review) methods. Data will be analysed retroductively. The study will comprise three Phases. In Phase 1, we will understand actors' expectations of responsive health systems, identify key priorities for interventions, and using evidence from a realist synthesis we will develop an initial theory and generate a baseline data. In Phase 2, we will co-produce jointly with key actors, the context-sensitive interventions to improve health systems responsiveness. The interventions will seek to improve internal (i.e. intra-system) and external (i.e. people-systems) interactions through participatory workshops. In Phase 3, we will implement and evaluate the interventions by testing and refining our initial theory through comparing the intended design to the interventions' actual performance.

DISCUSSION

The study's key outcomes will be: (1) improved health systems responsiveness, contributing to improved health services and ultimately health outcomes in Ghana and Vietnam and (2) an empirically-grounded and theoretically-informed model of complex contexts-mechanisms-outcomes relations, together with transferable best practices for scalability and generalisability. Decision-makers across different levels will be engaged throughout. Capacity strengthening will be underpinned by in-depth understanding of capacity needs and assets of each partner team, and will aim to strengthen individual, organisational and system level capacities.

The Utilization of Maternal Healthcare Services Among Ethnic Minority Populations in Vietnam

BACKGROUND

Previous studies have observed lower utilization of maternal healthcare services by ethnic minority groups in Vietnam compared with the majority Kinh community. This study sought to assess the utilization of maternal healthcare service-associated factors within 12 ethnic minority groups.

METHOD

The cross-sectional study enrolled 996 women from 12 ethnic minority groups in Vietnam in 2019. Women had pregnancy outcomes in the last 5 years. The two variables for maternal healthcare utilization were [1] a minimum of four antenatal contacts and [2] health facility-based delivery. We examined the association of individual characteristics of maternal healthcare services using multilevel modeling. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported.

RESULTS

This nationally representative study found that 34.1% of women from ethnic minority backgrounds had four or more antenatal contacts during pregnancy, ranging from 8.3% in Mong community to 80.2% in Cham An Giang. Most of the women (94.4%) delivered at health facilities. Factors independently correlated with having fewer than four antenatal contacts included being illiterate, early marriage, unemployment, religious affiliation, household economy, and distance to the nearest health facility. Factors significantly associated with home delivery were living in the most disadvantaged areas and having fewer than four antenatal contacts.

CONCLUSION

Substantial inequity exists in antenatal coverage both within ethnic minority groups and between socio-economic groups. The low coverage of having at least four antenatal contacts and its' correlates with facility-based delivery suggests that the government should focus efforts on increasing the number of antenatal contacts for ethnic minority women.

Utilization of Services Provided by Village-Based Ethnic Minority Midwives in Vietnam: Lessons From Implementation Research

BACKGROUND

Global progress in reducing maternal mortality requires improving access to maternal and child health services for the most vulnerable groups. This article reports results of implementation research that aimed to increase the acceptability of village-based ethnic minority midwives (EMMs) by local communities in Vietnam through implementing an integrated interventions package.

METHODS

The study was carried out in 2 provinces in Vietnam, Dien Bien and Kon Tum. A quasi-experimental survey with pretest/posttest design was adopted, which included 6 months of intervention implementation. The interventions package included introductory "launch" meetings, monthly review meetings at community health centers, and 5-day refresher training for EMMs. A mixed-methods approach was used involving both quantitative and qualitative data. A structured questionnaire was used in the pre- and posttest surveys, complemented by in-depth interviews and focus group discussions with EMMs, relatives of pregnant women, community representatives, and health managers.

RESULTS

Introductions of EMMs to their local communities by local authorities and supervision of performance of EMMs contributed to significant increases in utilization of services provided by EMMs, from 58.6% to 87.7%. Key facilitators included information on how to contact EMMs, awareness of services provided by EMMs, and trust in services provided by EMMs. The main barriers to utilization of EMM services, which may affect sustainability of the EMM scheme, were low self-esteem of EMMs and small allowances to EMMs, which also affected the recognition of EMMs in the community.

CONCLUSIONS

Providing continuous support and integration of EMMs within frontline service provision and ensuring adequate local budget for monthly allowances are the key factors that should allow sustainability of the EMM scheme and continued improvement of access to maternal and child health care among poor ethnic minority people living in mountainous areas in Vietnam.

Socioeconomic inequalities in post-natal health checks for the newborn in Vietnam

Background

The newborn and child death associated with inadequate post-natal health checks continued to be a significant issue across the world. This study aimed to assess the socioeconomic inequalities in post-natal health checks for the newborn in Vietnam in 2014.

Methods

We used the secondary data from the Multiple Indicator Cluster Survey in 2014. We included women aged 15–49 years who had a live birth within two years of the time of the interview. We estimated the concentration index to measure socioeconomic inequalities post-natal health checks for the newborn. We conducted multiple logistic regression analysis to identify factors associated with post-natal health checks for the newborn.

Results

Overall, the proportion of post-natal health checks for the newborn in Vietnam was 89.1%. The concentration index of post-natal health checks for the newborn was positive at 0.06. It indicated that the newborns in the rich households were more likely to get post-natal health checks as compared to in the poor households. The common factors significantly associated with the higher percentage of post-natal health checks for the newborn were women belonging to the Kinh and Hoa ethnic, higher education, and wealthier groups.

Conclusion

Socioeconomic inequalities in post-natal health checks for the newborn in Vietnam were not strong, but it still existed. Thus, we recommended that policy efforts to increase access to post-natal health services for poor women. In addition, there is a need to improve access to post-natal health services for women belonging to minor ethnic group and low education.

Distributed Health Literacy in the Maternal Health Context in Vietnam

BACKGROUND

Previous health literacy research has often focused on individual functional health literacy, ignoring the cultural contexts through which many people experience health care.

OBJECTIVE

We aimed to explore the nature of maternal health literacy among ethnic minority women in a low-resource setting in Vietnam.

METHODS

Using a qualitative approach, we conducted focus groups with 42 pregnant women, mothers, and grandmothers of children younger than age 5 years from the Thai and Hmong ethnic groups. Semi-structured interviews were conducted with key informants and thematic analysis was performed.

KEY RESULTS

The findings of our thematic analysis aligned well with the concept of distributed health literacy. We found that ethnic minority women drew upon family and social networks of health literacy mediators to share knowledge and understanding, assess and evaluate information, communicate with health professionals, and support decision-making. Family members were also involved in making health decisions that had the potential to negatively affect women and children's health.

CONCLUSIONS

Family members are an important source of information for ethnic minority women, and they influence decision-making. Relatives and husbands of pregnant women could be included in maternal health education programs to potentially strengthen the health literacy of the whole community. The distributed health literacy concept can be used to strengthen health promotion messages and to reduce the risk of negative health outcomes. [HLRP: Health Literacy Research and Practice. 2019;3(1):e31-e42.].

PLAIN LANGUAGE SUMMARY

Distributed health literacy refers to how health literacy skills and practices are distributed through social networks. This concept applies well to the maternal health context in Vietnam. Older women are trusted sources of information, and family influences decision-making during pregnancy. Women's limited autonomy increases the importance of family involvement. Distributed health literacy could be used to strengthen health promotion messages.

Contribution of health workforce to health outcomes: empirical evidence from Vietnam

BACKGROUND

In Vietnam, a lower-middle income country, while the overall skill- and knowledge-based quality of health workforce is improving, health workers are disproportionately distributed across different economic regions. A similar trend appears to be in relation to health outcomes between those regions. It is unclear, however, whether there is any relationship between the distribution of health workers and the achievement of health outcomes in the context of Vietnam. This study examines the statistical relationship between the availability of health workers and health outcomes across the different economic regions in Vietnam.

METHODS

We constructed a panel data of six economic regions covering 8 years (2006-2013) and used principal components analysis regressions to estimate the impact of health workforce on health outcomes. The dependent variables representing the outcomes included life expectancy at birth, infant mortality, and under-five mortality rates. Besides the health workforce as our target explanatory variable, we also controlled for key demographic factors including regional income per capita, poverty rate, illiteracy rate, and population density.

RESULTS

The numbers of doctors, nurses, midwives, and pharmacists have been rising in the country over the last decade. However, there are notable differences across the different categories. For example, while the numbers of nurses increased considerably between 2006 and 2013, the number of pharmacists slightly decreased between 2011 and 2013. We found statistically significant evidence of the impact of density of doctors, nurses, midwives, and pharmacists on improvement to life expectancy and reduction of infant and under-five mortality rates.

CONCLUSIONS

Availability of different categories of health workforce can positively contribute to improvements in health outcomes and ultimately extend the life expectancy of populations. Therefore, increasing investment into more equitable distribution of four main categories of health workforce (doctors, nurses, midwives, and pharmacists) can be an important strategy for improving health outcomes in Vietnam and other similar contexts. Future interventions will also need to consider an integrated approach, building on the link between the health and the development.
