Readiness to transition to HPV self-collection from VIA screening: a mixed methods health systems assessment from Tamil Nadu, India
As a frontrunner in introducing cervical screening in India, the state of Tamil Nadu urgently needs to consider how to improve screening rates and switch to Human Papillomavirus (HPV) detection tests. We used a mixed methods design to assess the readiness of the state health system for delivering the current cervical screening program, as well as for future HPV self-collection. Following a desk review, we surveyed 14 government health facilities in three districts of Tamil Nadu and calculated overall and domain-specific (service utilization, service availability, general service, cervical screening) readiness scores as percentages. We conducted four interviews and five focus group discussions with 37 participants [managers, primary care nurses, community health workers (CHWs)] to clarify findings and obtain suggestions regarding the introduction of HPV self-collection in tribal, rural, and urban low-resource settings. Scores for general services and readiness to offer visual inspection with acetic acid (VIA) and follow-up were more than 70% in the surveyed facilities. Despite the availability of trained nurses, infrastructure and resources, utilisation was primarily limited to symptomatic women attending health facilities due to poor acceptability of screening that would require facility visits. Most participants felt that self-collection could reduce women's fear and embarrassment and could be delivered through CHWs in the community or by nurses at facilities. However, motivation for screening may remain low as most asymptomatic women do not perceive a need for screening, and/or fear implications of a positive test. Tertiary laboratories appear ready for HPV testing, given availability of high-throughput PCR equipment, computerised laboratory information management systems, and a planned hub and spoke model of improving access to laboratory tests. Despite relatively good infrastructure and staffing for VIA screening in public healthcare facilities, service utilisation was primarily by symptomatic women, contributing to low screening rates. HPV self-collection was highly acceptable to administrative and field staff. Widespread educational approaches to motivate asymptomatic women to screen using self-collection, with decentralised sample collection and treatment, could potentially improve cervical screening rates.
