Motivations and hesitations for cervical cancer screening: considerations for scale-up of human papilloma virus (HPV) testing within HIV care in Zimbabwe
摘要
Consistent with WHO guidance Zimbabwe is transitioning from annual single visit screen-and-treat using visual inspection with acetic acid and cervicography (VIAC) to HPV testing every three years to screen women living with HIV (WLHIV) for cervical cancer.
MethodsWe administered a questionnaire at three public-sector facilities in Zimbabwe to understand reasons why WLHIV accept or decline VIAC and preferences for implementation of HPV testing.
ResultsA total of 451 WLHIV completed the questionnaire, of whom 414 (91.8%) accepted VIAC screening and 37 (8.2%) declined screening. Close to 50% of the 37 women who declined screening indicated a preference for HPV testing. The majority of WLHIV (76.3%) had known their HIV positive status for ≥ 5 years and nearly all (99.8%) were on antiretroviral therapy. Among the 414 WLHIV accepting VIAC screening, 323 (78.0%) were re-screening, and 91 (22.2%) were screening for the first time. WLHIV accepting VIAC re-screening were motivated by healthcare workers helping them feel secure about their health (45.8%), compliance with annual screening recommendations (39.6%), and encouragement from a healthcare worker (8.0%). Those accepting VIAC screening for the first time were motivated by encouragement from a healthcare worker (39.6%), compliance with annual screening recommendations (38.5%), and helping them feel secure about their health (17.6%). When asked what screening approach they would prefer in the future, the majority of women accepting re-screening (70.3%) and first-time screeners (89%) indicated a preference for continuing with VIAC screening. The 93 WLHIV with a screening history who indicated a preference for HPV testing were evenly split between preferring provider-collected sampling (13.9%) and self-collected sampling at the health facility (13.6%). Fear of physical discomfort of a pelvic exam (54.1%), worry about the screening result (13.5%), and perceived side effects of VIAC (10.8%) were the most common reasons given by the 37 WLHIV who declined VIAC.
ConclusionsFacilities transitioning to HPV testing will need to incorporate client-centered education that acknowledges existing individual commitment to VIAC, explains the benefits of HPV testing, and offers HPV self-sampling for WLHIV who are hesitant to undergo a pelvic exam.
