Health Literacy Interventions to Overcome Disparities in CRC Screening
Health Literacy Interventions to Overcome Disparities in CRC Screening
In the proposed project the investigators will evaluate two different follow-up approaches to improve low income patients' completion of initial and annual colorectal cancer (CRC) screening using the Fecal Immunochemical Test (FIT), the most sensitive FOBT. The purpose of this study is to compare the effectiveness of two distinct follow-up strategies to promote CRC screening: a prevention coordinator (PC) approach vs. an automated telephone reminder (ATR) system. The investigators will adapt a successful intervention tested in the Health Literacy and Cancer Screening Project by adding a follow-up strategy to the health literacy intervention. Specific Aims: The investigators Primary Aims are to: 1. Compare the effectiveness of the PC and ATR strategies to improve initial and repeat CRC screening. 2. Compare the cost effectiveness of the PC and ATR strategies for initial and repeat CRC screening. The investigators Secondary Aims are to: 3. Conduct a process evaluation of both follow-up strategies to investigate implementation and barriers 4. Determine if the effects of either strategy vary by patients' literacy skills. 5. Explore patient characteristics associated with CRC screening knowledge, beliefs, self-efficacy, and compliance over time between study arms.
The investigators objective is to compare the effectiveness of two distinct follow-up strategies to promote colorectal cancer screening: a prevention coordinator (PC) approach vs. an automated telephone reminder (ATR) system. The investigators will adapt a successful intervention tested in the Health Literacy and Cancer Screening Project [R01CA115869] by adding a follow-up strategy to the health literacy intervention. In the proposed project the investigators will evaluate two different follow-up approaches to improve low income patients' completion of initial and annual CRC screening using Fecal Immunochemical Test (FIT).
Substantial evidence shows that routine screening can prevent colorectal cancer (CRC) or detect it at an early stage, reducing related mortality. While overall CRC screening rates in the US are increasing, rates remain persistently low among uninsured and low-income individuals, those with fewer years of education, and racial/ethnic minorities. Low health literacy has been linked to cancer screening noncompliance, higher rates of advanced stage of presentation of disease and health disparities. In response, the Department of Health and Human Services has called for health information and services that are accurate, accessible, and actionable as well as culturally appropriate.
This study will implement a two-arm, randomized controlled trial with low income, underinsured patients in federally qualified health centers (FQHCs) to evaluate and compare the effectiveness of PC and ATR follow-up strategies to increase CRC screening. All patients recruited to the study will receive evidence-based, literacy appropriate screening materials developed using health literacy 'best practices' and a simplified FIT kit. Use of these materials has been shown to significantly increase CRC screening rates in the investigators ongoing study. Patients will be randomized to receive either: 1) the PC follow-up strategy, in which a PC personally reminds patients to complete and mail FIT kits, and perceived barriers to screening are discussed and addressed; or 2) the ATR follow-up strategy, in which an automated system electronically encourages patients to complete and mail FIT kits using plain language messages. The effectiveness of these two approaches will be compared at 12 and 24 months.
