RESUMEN
BACKGROUND: Cervical cancer screening programs that use visual inspection with acetic acid to identify women with pre-cancerous lesions in Zimbabwe have had limited success due to challenges with human resource constraints and patient acceptability. Nucleic acid amplification tests for human papillomavirus (HPV) have been endorsed by the World Health Organization for cervical cancer screening, along with self-collection of samples. As evidence shows self-collected sampling to be acceptable and preferable, Zimbabwe's Ministry of Health and Child Care (MOHCC) required a comparative analysis on the agreement between self- and clinician-collected samples for testing with Hologic Aptima HPV mRNA assay, to determine if self-collected samples could be used as another method to increase coverage of cervical cancer screening programs. METHODS: In four public health facilities in Zimbabwe from July to August 2020, self- and clinician-collected HPV samples were obtained from HIV-positive women aged 30-49 years for HPV testing. RESULTS: A total of 280 self- and clinician-collected samples were tested and results were found to have good agreement (κ: 0.75, 95% CI: 0.66-0.82). HPV prevalence was 43.0% (95% CI: 37.0%-49.3%) for self-samples and 48.0% (95% CI: 41.0%-54.2%) for clinician-samples. CONCLUSIONS: Self-collected sampling had good agreement with clinician-collected and its inclusion in the national cervical cancer screening policy by Zimbabwe's MOHCC is expected to increase testing coverage, especially among underserved communities such as women living with HIV, as well as decentralize access to cervical cancer screening services for lower-level facilities and increase the geographical scope of where HPV testing can be offered through the country.
