Experience with HPV self-sampling and clinician-based sampling in women attending routine cervical screening in the...

Several countries offer HPV self-sampling for screening non-attendees. It is assumed that screening attendees also prefer self-sampling to clinician-based sampling, however, little research has been conducted with respect to this. Women participating in the IMPROVE-study were randomised (1:1) to self- or clinician-collected HPV testing, and HPV-positive women were retested using the other collection method. Three different questionnaires were sent out among a subset of participating women: Q1) HPV-positive women from both study groups were asked about their experiences with self-sampling and clinician-based sampling (n = 497); Q2) HPV-negative women from the self-sampling group were asked about their experiences with self-sampling (n = 2366); and Q3) HPV-negative women in the clinician-collection group were asked about their experiences with clinician-based sampling (n = 2092). Response rates ranged from 71.6 to 79.4%. Women reported significantly lower levels of shame, nervousness, discomfort and pain during self-sampling compared to clinician-based sampling. However, trust in correct sampling was significantly higher during clinician-based sampling. The majority of women in group Q1 preferred self-sampling (76.5%) to clinician-based sampling (11.9%) in future screening, while 11.6% of women reported to have no preference for either method. To conclude, women from a regular screening population have a positive attitude towards self-sampling but express some concerns with respect to accuracy. The majority prefers self-sampling to clinician-based sampling in future screening. Based on these results, a screening approach where women can choose for either self-sampling or clinician-based sampling seems highly justifiable.
