<div><p>Background</p><p>Fetal monitoring in low-resource settings is often inadequate. A mobile cardiotocograph fetal monitoring device is a digital innovation that could ensure the safety of pregnant women at high risk and their fetuses through early detection and management of fetal distress. Research is scarce on factors that affect the implementation of fetal heart monitoring using the mobile cardiotocograph device in low-resource settings, including Tanzania. This study aimed to explore the barriers and facilitators of fetal monitoring with a mobile cardiotocograph device in Tanzania.</p><p>Methods</p><p>We adopted an exploratory qualitative study to analyze the barriers and facilitators of fetal monitoring using the mobile cardiotocograph device in primary healthcare facilities. Seventeen face-to-face in-depth interviews with healthcare providers and seven focus group discussions with women were conducted. Braun and Clarke’s thematic analysis guided the data analysis. It included the following steps: familiarizing with data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report.</p><p>Results</p><p>Three themes emerged as barriers: individual-related ones, including inadequate knowledge and skills to use mobile cardiotocograph devices, institutional barriers attributed to limited referral infrastructures and staff shortage, and community-related barriers, such as myths and misconceptions that limit antenatal care checkups. Individual factors, including motives and desires of healthcare providers and community trust in the healthcare system, support systems related to training and mentorship opportunities for healthcare providers, and the availability of community-based health programs in the respective areas, were revealed as facilitators of mobile cardiotocograph devices.</p><p>Conclusion</p><p>Implementing iCTG in primary healthcare facilities is affected by several factors, from individual to institutional level. Providing user-friendly procedure manuals and training on the functions of the iCTG device and cardiotocograph interpretations could serve as potential solutions to improve the competence and confidence of healthcare providers. Moreover, the availability of supportive infrastructure, adequate human resources for health, and community sensitization were good points to start with when addressing institutional and community barriers. Nevertheless, multistakeholder engagement during the design and implementation of fetal monitoring using a mobile cardiotocograph device is warranted.</p></div>
