Self-sampling for human papilloma virus DNA as a strategy to increase access to cervical cancer screening: patients' and providers' perspectives on facilitators and barriers to scale.

Self-sampling represents a high accuracy approach to human papilloma virus DNA (HPV-DNA) testing that allows for privacy and autonomy. As part of a larger study to evaluate cervical cancer screening in Mozambique, we explored user-driven facilitators and barriers to, and provider perspectives on, self-sampling. Our study was conducted in 4 public health facilities in 2 districts in Mozambique. Women aged 30-49 were prospectively enrolled for HPV screening and were offered provider or self-collected sampling. We used enrolment data from 9014 participants to examine characteristics of women choosing self-sampling and conducted in depth interviews with 104 women and 15 providers to understand facilitators and barriers to self-sampling. 97.5% of participants chose self-sampling over provider sampling. Participant-reported barriers included fear about technique, discomfort and inadequate training. Facilitators to self-sampling included increased privacy and having been exposed to a peer who previously self-sampled. Providers expressed concern about their limited role in the screening process with a self-sampling technique. Self-sampling for HPV is an acceptable approach to cervical cancer screening but barriers such as fear of sampling incorrectly and discomfort with their bodies remain.
