Plain English Summary
Background and study aims
Pregnant women attend health facilities to receive conventional antenatal care, but women at highest risk of morbidity (illness) and mortality (death) are least able to attend. Typically, they are socially isolated, overworked, poor, subject to gender violence and poorly educated. Nigeria has one of the highest rates of maternal mortality in the world, estimated as 576 deaths per 100,000 live births nationally and higher in Bauchi state. The Nigerian government has identified maternal mortality as a priority issue. Previous work in Bauchi state found four key links with negative outcomes of pregnancy: domestic violence, heavy work, lack of knowledge of danger signs, and lack of spousal communication about pregnancy. This study aims to answer the following questions:
1. Are universal home visits to pregnant women feasible and acceptable in northern Nigeria and what is their impact on pregnancy outcomes for mothers and babies?
2. How does adding video edutainment affect the feasibility and impact on pregnancy outcomes for mother and child?
3. In what way do home visits have an impact on pregnancy outcomes?
Who can participate?
Women of childbearing age (aged 14-49) living in six wards of Toro Local Government Authority (LGA) who are pregnant or who become pregnant during the study
What does the study involve?
The study tests the impact on mothers’ health of visiting all pregnant women every two months during their pregnancy and after delivery. In the visits, the female visitors ask them some questions about their health and discuss with them evidence about some problems that affect the outcome of pregnancy, and that can be tackled within the household: domestic violence, heavy work during pregnancy, lack of knowledge about danger signs of pregnancy, and lack of communication about pregnancy between women and their partners. Male workers visit the partners of the pregnant women to have the same discussions. The home visitors advise women with danger signs in their pregnancy to visit a health facility and provide a referral note for them. In half of the wards, the home visitors also show video clips to help the discussions about the problems that affect pregnancy outcomes. By the end of the study, all six wards have home visits in place. During the study, wards with home visits in place are compared with wards with home visits not yet in place. This includes comparing the number of deaths of mothers in visited and unvisited wards.
What are the possible benefits and risks of participating?
The intention of the home visits is to improve the health of pregnant women and their unborn children. The potential benefit of participating is a healthier pregnancy and a healthier baby. No risks are anticipated.
Where is the study run from?
Researchers from the department of Family Medicine at McGill University, Montreal, Canada, working in collaboration with staff of the Federation of Muslim Women Association of Nigeria (FOMWAN) in Bauchi, together with the Primary Health Care Development Agency (PHCDA) of the Ministry of Health, Bauchi State, Nigeria
When is the study starting and how long is it expected to run for?
August 2015 to May 2020
Who is funding the study?
The study is supported under the IMCHA programme (Innovating for Maternal and Child Health in Africa) with funding from the International Development Research Centre (IDRC) in Canada, Canadian Institutes for Health Research (CIHR) and Global Affairs Canada (GAC)

Video edutainment at the doorstep: impact on maternal and infant outcomes in Toro local authority in Bauchi state, Nigeria: a stepped wedge cluster randomised controlled trial
1. Are universal home visits feasible, acceptable and appropriate in areas of northern Nigeria other than Giade?
2. How does adding evidence-based video edutainment affect the feasibility, impact on maternal/infant outcomes, and cost of universal home visits?

Maternal and infant morbidity and mortailty
Six wards in Toro Local Government Authority (LGA) in Bauchi State, Nigeria, are randomly allocated (allocation by statistician outside the local study team) to three waves of two wards. The study uses central, computer based randomisation by an epidemiologist not associated with the fieldwork. The randomisation is of whole districts, into intervention waves of 5 districts each, rather than randomisation of individuals. The duration of the intervention is three years. At this point, the primary and secondary outcomes will be measured in the five first wave (intervention) districts and in the five second wave districts, serving as the controls for the first wave districts.
The “treatment” is a package of structural interventions implemented in the five districts allocated to the first wave. The study tests the impact on mothers’ health of visiting all pregnant women every two months during their pregnancy and after delivery. In the visits, the female visitors ask them some questions about their health and discuss with them evidence about some problems that affect the outcome of pregnancy, and that can be tackled within the household: domestic violence, heavy work during pregnancy, lack of knowledge about danger signs of pregnancy, and lack of communication about pregnancy between women and their partners. Male workers visit the partners of the pregnant women to have the same discussions. The home visitors advise women with danger signs in their pregnancy to visit a health facility and provide a referral note for them. In half of the wards, the home visitors also show video clips to help the discussions about the problems that affect pregnancy outcomes.
Primary outcome measure

2. Maternal mortality
3. Infant morbidity
Secondary outcome measures
1. Items in the CASCADA model of Conscious knowledge, Attitudes, Subjective norms, intention to Change, Agency, Discussion and Action, measured using a questionnaire administered in the household survey after 3 years
2. Feasibiity and acceptability of the home visits, assessed using household cluster survey after 3 years
