Purpose: HPV self-sampling has previously been shown to increase cervical cancer screening among ethnic minority and immigrant women. We conducted a randomized pragmatic trial to examine the effectiveness of HPV self-sampling delivered via in-person versus by US mail for medically underserved Hispanic, Haitian, and non-Hispanic Black women living in South Florida.
Methods: We randomized women aged 30-65 who had not completed Pap smear screening in the past 3 years into two groups: (1) HPV self-sampling delivered in-person (IP) by a community health worker (CHW; IP + SS) or (2) HPV self-sampling delivered via US mail (SS + Mail). Our primary outcome was HPV self-sampling completion by 6-month post-study enrollment.
Results: We enrolled 600 women. Approximately 65% were Hispanic and 35% were Haitian or non-Hispanic Black. Nearly half (43%) had an income of less than $20,000/year and 67% were uninsured. In intent-to-treat analyses, 71.6% of participants in the SS + Mail group and 81.0% of participants in the IP + SS group completed HPV self-sampling.
Conclusion: Mailed HPV self-sampling is an effective strategy to increase cervical cancer screening among underserved immigrant and ethnic minority women.
