Perceived barriers to self-collected HPV testing for cervical cancer screening, and knowledge of HPV: a survey of primary healthcare smear-takers across Aotearoa New Zealand.

Abstract

Cervical cancer remains a burden within Aotearoa New Zealand, with 2022 screening rates sitting 12.7% below target. The National Cervical Screening Programme has changed to primary human papillomavirus (HPV) testing for all screen-eligible people, with the aim for home self-testing. Little is known about the readiness of primary care for the change to self-testing and its associated challenges. A pilot HPV cervical cancer screening programme is being conducted in 17 practice centres. The aim of this study is to explore smear-taker knowledge at these centres about the use of primary HPV testing for cervical cancer screening. This is an ethically approved questionnaire study, with data from a structured web-based questionnaire sent to all smear-takers at the pilot centres. We achieved a total completion rate of 57.8%. The average score for "Knowledge of HPV" was 56.5% (range=20-100%). The challenges to patient home HPV self-testing were felt to be overall "not at all" to "mildly challenging". Up to 73.3% of participants identified ongoing needs for further education. The findings indicate knowledge deficits regarding HPV testing for cervical cancer screening and a desire for the provision of further education. Overall, respondents felt that no major barriers to implementing HPV self-testing would occur.
