Mapping the cervical cancer screening cascade among women living with HIV in Johannesburg, South Africaa.

OBJECTIVE: To map the cervical cancer screening cascade among women living with HIV attending a public-sector cytology screening program in Johannesburg, South Africa. METHODS: We conducted a retrospective cohort study of routinely collected clinical data captured in an electronic medical record system. Women (≥18 years) living with HIV with an abnormal Pap result between January 2013 and May 2018 were included. The proportion of women who received follow-up consistent with extant clinical guidelines, stratified by their initial Pap smear result, was examined. RESULTS: The study included 2072 women: 1384 (66.8%) with a low-risk Pap result, 681 (32.9%) with a high-risk Pap result, and 7 (0.3%) with suspected cancer. Only 174 (25.6%) women with a high-risk Pap result underwent guideline-indicated management within 18 months. Among women with a low-risk Pap result, 375 (27.1%) received follow-up within 1 year; the cumulative incidence of follow-up increased to 63.1% at 3 years. All women with suspected cancer either received a colposcopic biopsy or were referred for further treatment. CONCLUSION: Attrition among South African women living with HIV who attended cervical screening in an urban public-sector program was high. Developing tailored interventions to address bottlenecks in the care cascade and improve cervical screening outcomes will be central to eliminating cervical cancer.

Exploring women's preferences for HPV-based cervical cancer screening in South Africa.

OBJECTIVE: To determine preferences for HPV-based cervical cancer screening among South African women. METHODS: A discrete choice experiment survey was conducted among 298 women who attended two public-sector clinics in South Africa from February 1 to May 31, 2018. Participants chose between hypothetical screening scenarios: method of swab collection (self or provider); timing of treatment (same day or return visit); type of clinic (static or mobile); cost of services (US $0 or US $4); and time spent at the clinic (30, 60, or 120 minutes). A logistic regression model was generated to evaluate the importance of each attribute. A market simulation analysis was performed to determine potential uptake of the various screening strategies. RESULTS: The participants expressed strong preferences for free services (ß=0.50; P<0.001) and same-day HPV testing and treatment (ß=0.40; P<0.001). The market simulation indicated that 83.8% of women would be willing to undergo screening if services were free; the swab was collected by the provider; and treatment was offered at a return visit. Including same-day testing and treatment in the model increased uptake to 96.4%. CONCLUSION: Offering same-day HPV testing and treatment could substantially improve uptake of cervical cancer screening in the South African public healthcare sector.
