Prospective Evaluation of Self-Testing to Increase Screening (PRESTIS)

August 29, 2025 updated by: Jane Montealegre, Baylor College of Medicine

A Randomized Controlled Trial of Mailed Self-Sample HPV Testing to Increase Cervical Cancer Screening Participation Among Minority/Underserved Women in an Integrated Safety Net Healthcare System

Regularly attending for Pap test cervical cancer screening in a clinic is often unfeasible and/or unacceptable to many women. This study evaluates if mailing and testing self-sampled kits for high-risk human papillomavirus (HPV) can cost-effectively increase screening participation among underserved minority women in a safety-net health system.

Detailed Description

Regularly attending for Pap test cervical cancer screening in a clinic is often unfeasible and/or unacceptable to many women. Using mailed self-sampling kits to test for high-risk human papillomavirus (HPV), the virus that causes cervical cancer, may overcome multiple barriers to clinic-based screening. This study is a randomized controlled trial to compare the effectiveness of three outreach interventions to increase primary screening participation and clinical follow-up among underscreened women a in a safety net health system. The three strategies that will be evaluated are: 1) telephone recall; 2) telephone recall with mailed self-sample HPV testing kits; and 3) telephone recall with mailed self-sample HPV testing kits and patient navigation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Results of HPV test using self-collected samples (positive, negative, or inadequate)

Attendance to clinical follow up was assessed within 12 months of screening test result, up to 18 months post randomization.
