Barriers and facilitators for implementation of HPV-based cervical cancer screening in Tanzania: a qualitative study among healthcare providers, stakeholders, and Tanzanian women.

backgroundCervical cancer is the leading cause of cancer-related deaths in Tanzania and the most common form of cancer among Tanzanian women. Screening attendance remains among the lowest globally, necessitating improved attendance and screening methods.

objectiveThis study aims to assess the feasibility of implementing the World Health Organization's 2021 hPV-based screening guideline in Tanzania by identifying potential barriers and facilitators to HPV-based screening among screening clients, healthcare providers, and stakeholders.

methodsFrom October 2022 to February 2023, 25 semi-structured interviews were conducted with screening clients (

resultsBarriers and facilitators emerged across all levels of the Social Ecological Model. At the individual level, clinic-based screening and a one-visit approach were barriers, while HPV-self-sampling was a facilitator. Interpersonal barriers included limited social support, while referrals served as facilitators. Community-level barriers included fear and misconceptions, countered by facilitators such as increased awareness and health education. Health system challenges included restrictive age limits and urbanization of human resources, with uptake through other health services acted as a facilitator. Political barriers highlighted the need for a steady local supply chain, while cost reduction could serve as a facilitator for guideline implementation.

conclusionWHO's 2021 hPV-based screening guideline shows promise in Tanzania, but barriers such as clinic availability, fear, misconceptions, and supply chain issues must be addressed to ensure successful implementation.
