Out-reach Colposcopy Clinics and HPV Self-Sampling Decreases Loss to Follow up in a Community based Cervical Cancer Screening Programme.

objectiveTo introduce HPV self-sampling and out-reach colposcopy clinic as interventions to improve the follow-up of HPV positive women in a community based cervical cancer screening programme.

methodsThis was a prospective observational study conducted during October 2017 to August 2019 and 2977 women underwent cervical cancer screening using CareHPV test. Follow up colposcopy for HPV positive women were conducted at the rural health center and alternatively as out-reach clinics in their own villages and default rates were compared. HPV positive women were followed up at one-year. They were given an option of either having a follow-up HPV test performed by a health care worker (HCW) or by self-sampling. Compliance to follow up in these two modalities were compared. A validated questionnaire was given to women who had given an HPV self-sample to assess their awareness about HPV and cervical cancer.

resultsDuring our initial round of cervical cancer screening using HPV as a primary screening modality, our HPV screen positive rate was 7.05% (210 out of 2977 women screened).  Our colposcopy rates following an initial invitation at the rural health centre was only 28.5%. Following this, we initiated out-reach colposcopy clinics at their own villages for HPV positive women and this increased colposcopy rates from 28.5% to 45.2%. The participation rate at one-year follow-up was increased from 40.5% to 60% by the introduction of self-sampling as a follow up option and 16.2% of women who were initially positive remained HPV positive at 12-14 months follow up. All women who were offered the option of self-sampling preferred it over a HCW collected sample.

conclusionOur study showed that self-sampling could also be used effectively in the follow up of HPV positive women in the community. Outreach colposcopy clinics in their own villages enabled better follow up of HPV positive women.
