Development of mobile technologies for the prevention of cervical cancer in Santiago, Chile study protocol: a randomized controlled trial

BACKGROUND: In Chile, more than 500 women die every year from cervical cancer, and a majority of Chilean women are not up-to-date with their Papanicolau (Pap) test. Mobile health has great potential in many health areas, particularly in health promotion and prevention. There are no randomized controlled trials in Latin America assessing its use in cervical cancer screening. The ‘Development of Mobile Technologies for the Prevention of Cervical Cancer in Santiago, Chile’ study aims to determine the efficacy of a text-message intervention on Pap test adherence among Chilean women in the metropolitan region of Santiago. METHODS/DESIGN: This study is a parallel randomized-controlled trial of 400 Chilean women aged 25–64 who are non-adherent with current recommendations for Pap test screening. Participants will be randomly assigned to (1) a control arm (usual care) or (2) an intervention arm, where text and voice messages containing information and encouragement to undergo screening will be sent to the women. The primary endpoint is completion of a Pap test within 6 months of baseline assessment, as determined by medical record review at community-based clinics. Medical record reviewers will be blinded to randomization arms. The secondary endpoint is an evaluation of the implementation and usability of the text message intervention as a strategy to improve screening adherence. DISCUSSION: This intervention using mobile technology intends to raise cervical cancer screening adherence and compliance among a Chilean population of low and middle-low socioeconomic status. If successful, this strategy may reduce the incidence of cervical cancer. TRIAL REGISTRATION: Clinicaltrials.gov NCT02376023 Registered 2/17/2015. First participant enrolled Feb 22nd 2016.
