Cervical cancer is largely preventable through screening and preventive therapy. This is a cluster randomized trial that will integrate a novel cervical cancer screen-and-treat algorithm into voluntary family planning (VFP) services via two different models aimed at reducing barriers to screening and treatment in resource limited settings. Model 1 involves: 1) cervico-vaginal self-sampling for high-risk HPV (hr-HPV) while waiting for appointments at the VFP clinic or other clinics, 2) same-day visual inspection with acetic acid (VIA) for those women found to be hr-HPV-positive by rapid GeneXpert HPV testing, and 3) same-day thermocoagulation treatment for HPV-positive women who are eligible for ablative therapy by VIA. Model 2 will offer women the same services as in Model 1, but they will also be given the option to perform cervico-vaginal self-sampling in the community via Heath Surveillance Assistants (HSAs) who will bring their HPV sample to the clinic and notify them to return to the clinic for VIA and possible same-day thermocoagulation if their hr-HPV test is positive. Participants will be recruited from 16 high HIV-prevalence clinics in either Lilongwe in the Central Region or Zomba in the Southern Region. The broad objective of the project is to compare the effectiveness and budget impact of these two models for averting potential cervical cancer cases and to evaluate the implementation and acceptability of the models in multiple different health care facility settings. A systematic Implementation Evaluation will be conducted throughout implementation of the assigned models at the study health facilities to determine the success/failure in the delivery of intervention packages. The study team will employ the following mixed method data collection assessments: In-Depth Interviews with purposively selected healthcare facility staff and clients in the sampled facilities (N = approximately 60) Focus group discussions (FGDs) with purposively selected in-clinic services providers and HSAs (N = approximately 160) Structured weekly observations of service delivery by clinical mentors using an observation checklist, to observe providers and laboratorians adherence to standards, guidelines and intervention protocols Aggregate collection of routine quantitative service utilization data from adapted family planning and cervical cancer screening registers Implementation of assessment tools to assess changes in service providers' workload Client Exit Surveys with women in the catchment areas of the targeted facilities who received or declined family planning and/or cervical cancer screening services at the facility or in the community (N= approximately 1,000) Time and motion studies to observe visits and staff time spent on counseling, screening and treatment procedures, and managing and testing specimens. Finally, an Endline Household Survey will be completed among a random sample of women selected from all of the facilities' catchment areas (N= approximately 8,000). This survey will ask questions about basic demographic information, reproductive health information, HIV status, distance to the nearest health facility, prior VFP use, VFP use during project implementation, prior cervical cancer screening and preventive therapy (CCSPT) services received, and any CCSPT services received during project implementation.
