    Examining the impact of WHO’s Focused Antenatal Care policy on early access, underutilisation and quality of antenatal care services in Malawi : a retrospective study
    (BMC (part of Springer Nature), 2019-05-08) Mchenga, Martina; Burger, Ronelle; Von Fintel, Dieter
    Background: A variety of antenatal care models have been implemented in low and middle-income countries over the past decades, as proposed by the World Health Organisation (WHO). One such model is the 2001 Focused Antenatal Care (FANC) programme. FANC recommended a minimum of four visits for women with uncomplicated pregnancies and emphasised quality of care to improve both maternal and neonatal outcomes. Malawi adopted FANC in 2003, however, up to now no study has been done to analyse the model’s performance with regards to antenatal care service quality and utilisation patterns. Methods: The paper is based on data pooled from three comparable nationally representative Malawi Demographic and Health Survey (MDHS) datasets (2000, 2004 and 2010). The DHS collects data on demographics, socio-economic indicators, antenatal care, and the fertility history of reproductive women aged between 15 and 49. We pooled a sample of 8545 women who had a live birth in the last 5 years prior to each survey. We measure the impact of FANC on early access to care, underutilisation of care and quality of care with interrupted time series analysis. This method enables us to track changes in both levels and the trends of our outcome variables. Results: We find that FANC is associated with earlier access to care. However, it has also been associated with unintended increases in underutilisation. We see no change in the quality of ANC services. Conclusion: In light of the WHO 2016 ANC guidelines, which recommend an increase of visits to eight, these results are important. Given that we find underutilisation when the benchmark is set at four visits, eight visits are unlikely to be feasible in low-resource settings.

    Making under-resourced health systems work for vulnerable women and children : antenatal care in Malawi

    ENGLISH ABSTRACT : This thesis investigates the implementation barriers and adoption of maternal health care interventions in Malawi, a sub-Saharan African country with one of the highest maternal mortality rates and most poorly resourced health systems in the region. Although antenatal care has universal components that apply to all pregnant women, the guidelines are designed to be adaptable so that countries with different health system structures and burdens of disease can implement them according to their context and the needs of their population (Benova et al., 2018). However, a lack of empirical evidence, means it is difficult to know and assess whether the existing models of care are being successfully implemented and, furthermore, whether they achieve the intended – or even unintended – objectives and provide solutions for the future, especially in settings where resources are limited. This thesis attempts to address this gap. I focused on two major aspects of antenatal care (ANC): the supply aspect (quality of care) and the demand aspect (utilisation of care), to analyse three broad objectives. In the first objective, I examine the impact of the 2001 Focused Antenatal Care (FANC) model on quality of care and utilisation of ANC services in Malawi. In the second objective, I estimate the optimal number of visits that are effective in improving birth outcomes in low-resourced settings. In the third objective, I compare women’s self-reports on the quality of ANC received to the direct observation of facilities to understand how to counter biases and mismeasurements that can impede accurate local tracking of the quality of services provided. An examination of the impact of the 2001 World Health Organization FANC model on the utilisation, early access and quality of care in Malawi, using three comparable demographic and health datasets, and the interrupted time series analysis, confirms that, when it comes to policy, one size does not always fit all. The findings reveal that, although FANC only recommends a minimum number of four visits and is therefore potentially cost effective, in Malawi the model did not translate into improved quality of care and was found to be associated with the unintended consequence of increased underutilisation of ANC. It is therefore questionable whether revising the minimum number of visits from four to eight, as recommended by the 2016 WHO guidelines would be effective in low-resourced settings. Villar et al. (2002) noted that most ANC policies in low and medium-income countries (LMICs) are adopted without thorough scientific evaluation and that there is a lack of empirical evidence on the average number of visits likely to produce the most benefit in improving maternal and child health outcomes. Therefore, this thesis extends the analysis from objective one and estimates the number of visits that would be effective to improve birthweight in Malawi. Using nationally representative Malawi Demographic and Health Survey data, I apply instrumental variable models together with highly flexible non-linear spline specifications and Wald tests to estimate breaks in the relationship between the number of ANC visits and the probability of low birthweight. Results suggest that only three visits are required to reduce the probability of low birthweight to the same extent as more visits would. This implies that low-income health systems are likely to perform just as well if fewer routine visits are conducted with more attention to quality, and reserving additional ANC visits to women who critically need them. The analysis in the first two objectives takes advantage of the publicly available nationally representative household Malawi Demographic and Health Surveys, which are based on women’s self-reports on the services provided. However, the reliability of this data depends on a number of factors: the client’s ability to recall with accuracy; the client’s access to information and knowledge of the content of care; an understanding of the questions being asked and the ability to link them to what the provider was doing, among others. These highlighted limitations may lead to an upward or downward bias in the quality of care measurement, limiting the utility of survey results for programme improvement. Given that most LMICs rely on household and client exit surveys to obtain estimates of healthcare quality, accurate information on ANC quality is important. In this part of the thesis, therefore, I assess the extent to which women’s self-reports on the quality of ANC is congruent with facility-observed estimates by testing the sensitivity, specificity and receiver-operating curves (ROCs) of ANC quality components. The results suggest that women overestimate the quality of care, mainly due to a lack of knowledge about complicated items of ANC and an overall understanding of the questions beings asked in the surveys. For example, complicated quality components asking whether the provider had counselled the client on the side effects of iron and pregnancy-related complications had lower reporting accuracy than objective indicators asking whether the provider had prescribed medication for malaria prevention, and iron/folic tablets. The main recommendations in this regard are that, in measuring the quality of care, it is important to compare women’s self-reports to facility data to get accurate quality estimates; and that the emphasis needs to be on women to place them at the forefront of policy change by educating them on what to expect during healthcare consultations. The overall findings suggest that public policy has an important role to play when it comes to maternal preventive healthcare. Demand-side policy tools such as increased access to basic information on the importance of accessing ANC services and specific components to expect during a consultation can only be successful if the supply side is adequate and effective.
