Unlocking the mechanisms of change in the MAMAACT intervention to reduce ethnic disparity in stillbirth and newborns' health: integration of evaluation findings

Ethnic disparities in stillbirth exist in Europe and suboptimal care due to miscommunication is one contributing cause. The MAMAACT intervention aimed to reduce ethnic disparity in stillbirth and newborns' health through improved management of pregnancy complications. The intervention encompassed training of antenatal care midwives in cultural competencies and intercultural communication combined with health education materials for the expecting parents about symptoms of pregnancy complications. The evaluation consisted of a qualitative in-depth implementation analysis and a process evaluation embedded in a cluster randomized trial including 19 of 20 maternity wards in Denmark. In this article, the findings from the different evaluation perspectives are integrated. The integration follows the principles of realist evaluation by analyzing to what extent the MAMAACT activities were generating mechanisms of change in interaction with the context. The integration analysis shows that the health education materials in the MAMAACT intervention contributed to heightened health literacy concerning pregnancy complications among pregnant women. Additionally, the training of midwives in cultural competency and intercultural communication raised awareness among midwives. Nonetheless, the exclusive emphasis on midwives and the inflexibility in care provision hindered them from changing their communication practices. To enhance the cultural competence in maternity care, it is essential to implement more comprehensive initiatives involving healthcare professionals in maternity care at all levels, from pregraduate to postgraduate. Adequate interpreter services and management support should also be ensured. Currently, the Danish antenatal care system faces challenges including inadequate information transfer between healthcare sectors, insufficient differentiation of care, and inflexibility in midwife scheduling. This results in a lack of responsiveness to the individual needs of women with immigrant backgrounds, potentially reproducing health inequities.

Improving health literacy responsiveness to reduce ethnic and social disparity in stillbirth and infant health: A cluster randomized controlled effectiveness trial of the MAMAACT intervention

OBJECTIVE

The MAMAACT intervention aims to reduce ethnic and social disparities in stillbirth and infant death by improving communication between pregnant women and midwives regarding warning signs of pregnancy complications. This study evaluates the effect of the intervention on pregnant women's health literacy (two domains from the Health Literacy Questionnaire) and complication management - interpreted as improved health literacy responsiveness among midwives.

DESIGN

Cluster randomized controlled trial, 2018-2019.

SETTING

19 of 20 Danish maternity wards.

PARTICIPANTS

Cross-sectional survey data were collected using telephone interviews (n = 4150 pregnant women including 670 women with a non-Western immigrant background).

INTERVENTION

A six-hour training session for midwives in intercultural communication and cultural competence, two follow-up dialog meetings, and health education materials for pregnant women on warning signs of pregnancy complications - in six languages.

MAIN OUTCOME MEASURES

Differences in mean scores at post-implementation of the domains Active engagement with healthcare providers (Active engagement) and Navigating the healthcare system from the Health Literacy Questionnaire, and differences in the certainty of how to respond to pregnancy complication signs between women in the intervention and control group.

RESULTS

No difference was observed in women's level of Active engagement or Navigating the healthcare system. Women from the intervention group were more certain of how to respond to complication signs: Redness, swelling, and heat in one leg: 69.4 % vs 59.1 %; aOR 1.57 (95 % CI 1.32-1.88), Severe headache: 75.6 % vs 67.3 %; aOR 1.50 (95 % CI 1.24-1.82), and Vaginal bleeding: 97.3 % vs 95.1 %; aOR 1.67 (95 % CI 1.04-2.66).

CONCLUSION

The intervention improved women's certainty of how to respond to complication signs, but was unable to improve pregnant women's health literacy levels of Active engagement and Navigating the healthcare system, likely due to barriers related to the organization of antenatal care. A reorganization of antenatal care and a care model sensitive to diversity within the entire healthcare system might help reduce disparities in perinatal health.

Effectiveness evaluation of an antenatal care intervention addressing disparities to improve perinatal outcomes in Denmark: A nationwide register-based analysis of a cluster randomised controlled trial (MAMAACT)

OBJECTIVE

To evaluate whether MAMAACT, an antenatal care (ANC) intervention, aimed at reducing ethnic and social disparities in perinatal mortality, affected perinatal health outcomes.

DESIGN

Cluster randomised controlled trial.

SETTING

Nineteen of 20 maternity wards in Denmark.

POPULATION

All newborn children within a pre-implementation period (2014-2017) or an implementation period (2018-2019) (n = 188 658).

INTERVENTION

A 6-h training session for midwives in intercultural communication and cultural competence, two follow-up dialogue meetings, and health education materials for pregnant women on warning signs of pregnancy complications in six languages.

METHODS

Nationwide register-based analysis of the MAMAACT cluster randomised controlled trial. Mixed-effects logistic regression models were used to estimate the change in outcomes from pre- to post-implementation in the intervention group relative to the control group. Results were obtained for the overall study population and for children born to immigrants from low- to middle-income countries, separately. Models were adjusted for confounders selected a priori.

MAIN OUTCOME MEASURES

A composite perinatal mortality and morbidity outcome, including stillbirths, neonatal deaths, Apgar score <7, umbilical arterial pH < 7.0, admissions to a neonatal intensive care unit (NICU) >48 h, and NICU admissions for mechanical ventilation. Additional outcomes were the individual measures.

RESULTS

The intervention increased the risk of the composite outcome (adjusted odds ratio [aOR] 1.16, 95% confidence interval [CI] 0.99-1.34), mainly driven by differences in NICU admission risk (composite outcome excluding NICU, aOR 0.98, 95% CI 0.84-1.14). The intervention slightly increased the risk of low Apgar score and decreased the risk of low arterial pH, reflecting, however, small differences in absolute numbers. Other outcomes were unchanged.

CONCLUSIONS

Overall, the MAMAACT intervention did not improve the composite perinatal mortality and morbidity outcome (when excluding NICU admissions). The lack of effects may be due to contextual factors including organisational barriers in ANC hindering the midwives from changing practices.

Knowledge About How to Manage Warning Signs of Pregnancy Complications Among Immigrants and Their Descendants Compared to Women of Danish Origin

OBJECTIVES

Ethnic differences in perinatal morbidity and mortality are starting points for social inequality in health. Increased incidence and severity of some pregnancy complications are found among immigrant women compared to ethnic majority women in high-income settings. However, little is known about immigrant women's assessment and management of warning signs. We aimed to assess women's knowledge about how to manage warning signs of pregnancy complications among immigrants and their descendants compared to women of Danish origin.

METHODS

A cross-sectional study including phone-based interviews with 1899 women. Women were interviewed during gestational week 30-37 in one of six languages. Maternal ethnicity was categorized as; immigrants, their descendants and ethnic Danes. The outcomes were yes or no to; do you know what to do if you experience 1) sudden swelling, redness, and heat in one leg 2) severe headache and 3) vaginal bleeding.

RESULTS

Immigrant women had lower levels of knowledge about how to manage all three types of warning signs of pregnancy complications compared to women of Danish origin. Adjusted OR for vaginal bleeding for women of European (4.33, 95% CI: 2.24-8.37), Asian (9.26, 95% CI: 5.10-16.83) and African (8.66, 95% CI: 3.26-23.05) origin.

CONCLUSIONS FOR PRACTICE

Immigrant women had lower levels of knowledge about how to manage warning signs of pregnancy complications compared to women of Danish origin. Improved needs-based health education in pregnancy complications and body symptoms during antenatal care is needed to address delays in the management of complications and could potentially improve the health of women and children.

The Danish implementation study on response to pregnancy complications, MAMAACT

Differential incidence and severity of pregnancy complications are likely important contributing factors to the increased risk of poor pregnancy outcomes among ethnic minority women in Europe. To address this issue, the MAMAACT trial has been developed based on a thorough mixed methods needs assessment and co-creation process, feasibility tested, now implemented in a nationwide complex intervention. The overall aim of the Danish MAMAACT trial is to reduce ethnic and social disparity in stillbirth and newborns' health by improved management of pregnancy complications. The overall target group is all pregnant women, and the specific target group is women of non-Western origin. The hypothesis of MAMAACT is that improved communication between pregnant women and midwives regarding body symptoms that need prompt reaction will improve perinatal health among these vulnerable groups. The intervention consists of postgraduate training of midwives in intercultural communication and a smart phone application and a leaflet, both in six different languages. The app and leaflet target the women and explain the most serious warning signs of pregnancy complications and how to respond to them.

MAMAACT is implemented and evaluated in a randomized controlled cluster trial and 10 maternity wards consist the intervention groups, while nine maternity wards are the control groups. The evaluation is a mixed method evaluation focusing on understanding the mechanisms of change, how context at both maternity ward level as well as in the everyday life of women affects the implementation, and finally if effects on health literacy of the women and perinatal health of the children can be documented.

Ethnic differences in the risk of caesarean section: a Danish population-based register study 2004-2015

BACKGROUND

Studies have shown differences in the risk of caesarean section (CS) between ethnic minority groups. This could be a marker of unequal health care. The aim of this study was to investigate differences in the risk of CS between immigrants of various origins in Denmark, where all health care is free and easy to access, and Danish-born women. A further aim was to determine the possible influence of known risk factors for CS.

METHODS

The design was a population-based register study using national Danish registers and included all live- and stillborn singleton deliveries by primiparous women in Denmark from 2004 to 2015. The total study population consisted of 298,086 births, including 25,198 births to women from the 19 largest immigrant groups in Denmark. Multinomial logistic regression analysis was used to estimate relative risk ratios (RRR) of emergency and planned CS, using vaginal delivery (VD) as reference, in immigrant women compared to Danish-born women. A number of known risk factors were included separately.

RESULTS

Women from Turkey, the Philippines, Thailand, Somalia, Vietnam, Iran and Afghanistan had a statistically significant elevated risk ratio of emergency CS vs. VD compared to Danish-born women; adjusted RRR's ranging 1.15-2.19. The risk ratio of planned CS vs. VD was lower among the majority of immigrant groups, however higher among women from Poland, Thailand and Iran, when compared to Danish-born women. None of the studied explanatory variables affected the risk ratio of planned CS vs. VD, whereas maternal height contributed with varying strength to the risk ratio of emergency CS vs. VD for all immigrant groups.

CONCLUSION

Substantial variations in CS risks by maternal country of birth were documented. Some of the disparities in emergency CS seem to be explained by maternal height.
