Assessing implementation outcomes for launching balanced energy protein supplementation: A formative study in rural Bangladesh

Balanced energy protein (BEP) supplementation is an efficacious intervention in pregnancy for improving birthweight and is recommended by World Health Organization (WHO) in countries with high maternal undernutrition. Few countries have implemented BEP programmes due in part to high cost, lack of data on acceptability and feasibility, and complexity of delivery. We sought to address implementation gaps in BEP interventions through a formative study designed to understand implementation outcomes. We conducted 52 in-depth interviews and 8 focus-group discussions with married women of reproductive age, family members, health care providers and pharmacists in three unions of the Gaibandha district in rural Bangladesh. Interviews were translated and transcribed in English and analysed using an analytic framework for implementation science in nutrition. BEP was viewed as an acceptable and appropriate intervention to combat undernutrition in this setting. There was a lack of clarity on who should or could be responsible for providing/distributing BEP in a way convenient to mothers. Many participants preferred door-to-door delivery and thought this approach could address social and gender inequities, but providers mentioned already being overworked and worried about adding new tasks. Participants were concerned about the affordability of BEP and opportunity costs associated with travel to proposed distribution sites such as ANC or pharmacies. Women in these communities do not always have the agency to travel without supervision or make purchasing decisions. BEP supplementation is a complex intervention; future trials seek to assess ways to overcome these implementation challenges and inform a long-term systems-owned BEP intervention. While balanced energy protein supplementation is seen as an acceptable intervention by women, their families and health care providers, its implementation and rollout will be complex. Who bears the cost, who delivers the product and how it is delivered are important concerns which we will seek to address.image Balanced energy protein (BEP) supplementation is an efficacious intervention in pregnancy for improving birthweight but its implementation through ANC, as recommended by WHO, is complex.Decisions about who bears the cost of the product should consider the feasibility of scaling solutions to different groups. Targeting the most in need and with government supported programmes should be considered.Door-to-door distribution emerged as the preferred delivery modality, though the feasibility of this mechanism at scale is a concern, particularly given the documented lack of human resources in health.Given the positive community perceptions around BEP supplements, delivery through ANC could increase ANC participation.
