A Culturally Adapted Digital Intervention to Promote Maternal Care Utilization Using Multifaceted Approaches (CALCIUM) Among an Ethnic Minority Community in China
Maternal healthcare utilization is crucial for reducing maternal mortality, yet remains low in many underserved regions. The CALCIUM intervention, a culturally tailored, digital platform-integrated intervention, was developed to promote antenatal care (ANC) and institutional deliveries in Liangshan Yi Autonomous Prefecture, an ethnic minority community in China. The CALCIUM intervention was developed to address barriers including limited healthcare awareness, traditional norms and low-quality services. This intervention will evaluate the effectiveness, and cost-effectiveness of improving maternal healthcare utilization and pregnancy outcomes in an ethnic minority community.
A cluster quasi-randomised control trial will be conducted in two counties, Xide and Yuexi, in Liangshan Yi Autonomous Prefecture, Sichuan province, China. In total, 12 towns will be randomly selected from each of the two counties (i.e., Yuexi and Xide). Within each county, the selected towns will be randomly and evenly assigned to the intervention and control groups. In each town, 80 newly pregnant women will be invited to participate. The comprehensive intervention was designed based on the Behaviour Change Wheel (BCW) including digital health education via social media platform, capacity building for healthcare providers and economic incentives for village doctors. Primary outcomes include the rates of hospital delivery and ANC utilization. Secondary outcomes include participants' pregnancy-related diseases and pregnancy outcomes. Primary and secondary outcomes will be collected through the local maternal and newborn health monitoring system. Sociodemographic and process information will be gathered through postpartum interviews. A logistic mixed model with an intention-to-treat approach will be used to evaluate the effectiveness of the intervention. Additionally, intervention costs and cost-effectiveness will be assessed.
