Abstract Background The Maternal and Child Health (MCH) handbook is an integrated home-based record (HBR) designed to record in a single document all the information regarding health services provided to a pregnant woman and her child. The MCH handbook has the potential to support continuity of care which is key to strengthening maternal, newborn and child health. However, there is a lack of an integrated system to manage the health of pregnant women and young children on an ongoing basis in Angola. Thus, the Angolan Ministry of Health is partnering with the Japan International Cooperation Agency to build the capacity of healthcare providers through trainings and implementation of the MCH handbook to improve service utilisation. In this study, we will estimate the impact of an intervention package including distribution of MCH handbook and its supplementary interventions to women, on the utilisation of services provided at healthcare facilities from pregnancy through the postnatal and early childhood period. Methods This study is a cluster randomised controlled trial involving public healthcare facilities across all the municipalities located in Benguela Province, Angola. All women who go to participating healthcare facilities and with confirmed pregnancy around the beginning of the trial period will be included in the study. Women will be randomised according to the municipality where their primary maternity and/or childcare services are located. The intervention package will consist of MCH handbook distribution at all public healthcare facilities, MCH handbook utilisation training for healthcare providers and community mobilisation for women on the use of the MCH handbook. The intervention will be administered to all women in the intervention arm while those in the control arm will continue the traditional use of two stand-alone HBRs. The primary outcome measure for this study is to compare the proportion of women who achieve a complete continuum of care in both study arms. Discussion The findings from the study are expected to form a basis for revising the current trial version of the Angola MCH handbook and provide a framework for policy guiding nationwide scale-up and distribution of the MCH handbook.
