ABSTRACT: Home-based records are paper or electronic records retained and used by mothers or caregivers to document the health services received for maternal, newborn, and child health. Little has been studied about the roles of these records on newborn and child health outcomes. Hence, we collated and summarized evidence concerning the roles of home-based records in improving newborn and child health. We conducted a systematic search in several databases: MEDLINE, Web of Science, CINAHL, PsycINFO, PsycARTICLES, Academic Search Complete, SocINDEX, CENTRAL, DARE, NHS EED, HTA, J-STAGE, Ichushi, and gray literature. We included original research articles of all study designs published in English or Japanese until January 2020. Owing to heterogeneity across the outcomes of included studies, we conducted a narrative synthesis. We included 55 studies (23 in Japanese) among 14,017 identified articles. We identified the following roles of home-based records on newborn and child health: promoted newborn/childcare seeking, improved knowledge and practices of newborn/childcare, encouraged home care for childhood illnesses, reduced child mortality and morbidity, and facilitated continuum of care. We observed a mixed effect on age-appropriate immunization (e.g., DTP3 completion) and no effect on the practice of immediate breastfeeding and prevention of perinatal mortality and morbidity. The findings highlighted the effectiveness and usefulness of home-based records to improve newborn and child health outcomes. However, only a few studies were available for each outcome category, limiting the certainty of evidence provided in this review. Therefore, we recommend further studies to explore the benefits of home-based records on improving newborn and child health.
