Uptake of Cervical Cancer Screening in Ethiopia by Self-Sampling HPV DNA Compared to Visual Inspection with Acetic...

In Ethiopia, the standard method of cervical cancer screening is using Visual Inspection with Acetic Acid (VIA). Self-collection-based human papillomavirus (HPV) testing is assumed to improve the uptake of screening, especially for hard to reach populations. We investigated whether HPV DNA testing with the self-collection of cervical samples would be associated with increased uptake and adherence to procedures at the population level compared with VIA within defined rural population in Ethiopia. A total of 22 clusters (comprising 2,356 women ages 30-49 years) were randomized in two arms. Following the community mobilization, women of the clusters were invited to go either to the local health post for a self-collection-based HPV DNA testing (arm A) or Butajira Hospital for VIA screening (arm B). In the HPV arm, of the 1,213 sensitized women, 1,020 (84.1%) accessed the health post for self-sampling compared with the VIA arm, where 575 of 1,143 (50.5%) visited the hospital for VIA (P < 0.0001). Of those women who attended the VIA and HPV arms, 40% and 65.4% adhered to all procedures expected after screening, respectively. Out of women positive for high risk HPV, 122 (85%) attended VIA as a follow-up test. The trial demonstrated significantly higher levels of population-based uptake and adherence for self-collection HPV testing. Women were more receptive for VIA after their HPV testing result was positive. Self-collection HPV testing can be done at the local health facility and may significantly improve the uptake of cervical cancer screening in Ethiopia.
