Implementation fidelity of a multisite maternity waiting homes programme in rural Zambia: application of the conceptual framework for implementation fidelity to a complex, hybrid-design study

Background

Implementation fidelity measures are critical for understanding complex interventions. Though maternity waiting homes (MWHs) are recommended by the WHO and have been used to help pregnant women access health facilities for decades, a gap exists regarding fidelity studies on MWHs. To better understand intervention outcomes results, we assessed the fidelity of implementation of an improved Core MWH Model in 10 facilities in rural Zambia.

Methods

We analysed indicators for fidelity employing a widely used conceptual framework. We compared performance from October 2016 to July 2018 to goals set out during intervention design. The Core MWH Model consists of three pillars-infrastructure, policies and linkages to care-each designed to be culturally appropriate and responsive to community standards for safety and comfort.

Results

70% of sites exhibited high adherence to the Core MWH Model components. User experience corroborated poorer performing elements: insufficient lighting, small cooking spaces, non-locking cabinets and few educational classes. Mission statements and governing documents were not always visible or available. The proportion of 3206 users who came from>10 km away was higher than the proportion of the surrounding population living at that distance except in two sites with low populations of remote-living women. Women stayed for just below the target of 14 nights. MWH occupancy rate overall was lower (52%) than the target (80%). MWH users reported high quality and satisfaction. Only three MWHs reached 50% female membership on their governance committees but met other key indicators for community ownership and engagement.

Conclusions

This fidelity evaluation of an MWH model in rural Zambia helps bridge the evidence-practice gap for the WHO's recommendation on implementing MWHs and adds to the expanding body of literature on implementation fidelity studies in global health.

Realist evaluation of maternity waiting home intervention models in Inhambane, Mozambique: protocol for a comparative embedded case study, the Mozambique-Canada Maternal Health Project

INTRODUCTION

This is a study protocol that tests and refines realist theories regarding the uptake and scale-up of the linked maternity waiting home (hereafter MWH) and facility birth intervention in the Mozambican context. The theories were developed through a realist review of MWH-facility birth literature from low-income and middle-income countries. The aim of the proposed study is to contribute to a contextually refined understanding of the causal chains underlying MWH-facility birth adoption by pregnant women and their families, communities, the health system and donors.

METHODS AND ANALYSIS

The overarching methodology is mixed-methods realist evaluation. The study will adopt a comparative embedded case study design comparing three new masonry MWHs built by the Mozambique-Canada Maternal Health Project in Inhambane province with three older MWHs selected based on variation in the built environment. Baseline data on participating MWH-facility birth interventions will be collected through observations, reviews of routine data and analysis of statistics and reports from provincial and district health authorities and the Mozambique-Canada Maternal Health project. Realist interviews will be conducted with MWH users and non-users, companions of MWH users and non-users, partners of MWH users and non-users, and stakeholders within the health system and the non-governmental organisation sector. Realist focus groups will be used to collect data from community-level implementers. The analysis will be retroductive and use the context-mechanism-outcome configuration heuristic tool to represent generative causation. We will analyse data from intervention and comparator MWHs independently and compare the resulting refined programme theories. Data analysis will be done in NVivo 12.

ETHICS AND DISSEMINATION

Ethics approval for the project has been obtained from the Mozambique National Bioethics Committee (CNBS-Comité Nacional de Bioética para a Saúde) and the University of Saskatchewan Bioethical Research Ethics Board. The evaluation will adhere to the International Ethical Guidelines for Biomedical Research Involving Human Subjects and the African adaptation of evaluation ethics and principles. Evaluation results will be disseminated to stakeholders' practice audiences through peer-reviewed publications, plain-language briefs, theory validation/feedback meetings and conference presentations.
