Improving Communication and Management Following a Positive Home HPV Self-Sampling Result: Comparing Intervention Strategies Between the HOME and STEP Trials.

Background: Mailed human papillomavirus (HPV) self-sampling kits improve cervical cancer screening adherence. The HOME trial found information needs and anxiety among HPV-positive patients. We designed a STEP trial to test optimized intervention strategies with bolstered educational materials and a centralized nurse communicating positive results. Here, we evaluate the effect of the strategies by comparing interviews of HOME and STEP participants receiving HPV-positive results.

Materials and methods: STEP participants were interviewed during December 2021-March 2022, and asked about their kit reaction and nurse communication, and surveyed on attitudes toward the kit. Transcripts were analyzed in two phases: (1) Coders used iterative content analysis to organize codes into node reports and identify themes and (2) coders compared node reports between the HOME and STEP trials.

Results: Sociodemographic of 46 HOME and 28 STEP participants were similar (White, older, had prior Pap). Participants from both trials appreciated the kit's convenience, although some questioned its accuracy compared to clinician-performed screening. While many STEP participants were surprised by the positive result, most felt reassured by the nurse and understood the recommended follow-up. STEP participants expressed fewer negative emotions. More STEP than HOME participants believed the HPV result was correct (86% vs. 59%) and trusted it (90% vs. 65%). Willingness to recommend the HPV kit to a friend and use it in the future was high in both the trials.

Discussion: Qualitative comparison of HOME and STEP participants' reactions suggests STEP patients received the information needed to understand HPV-positive results and complete follow-up. Findings support a centralized nurse communicating results and building trust in this new screening technology.
