Low-Literacy Physician-Patient Intervention Promoting Colorectal Cancer Screening

Overview

The purpose of this study is to evaluate the effectiveness of a low literacy, physician and patient-directed intervention to promote colorectal cancer (CRC) screening among the medically underserved.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Health Services Research
    • Masking: Single (Participant)
  • Study Primary Completion Date: July 2013

Detailed Description

This study will test the separate and combined effect of two of these interventions: 1) a provider communication skills training using a continuous quality improvement (CQI) framework, and 2) a brief, multimedia Patient Education Program (PEP) that incorporates plain language, graphic design, and audio voice-over to overcome literacy limitations. Our provider intervention has demonstrated efficacy to significantly improve CRC screening recommendation rates. Our multimedia program has also been field tested among patients with limited literacy and was able to improve patient knowledge and intention to receive screening.

We will implement both provider-only and combined provider-patient strategies within a federally qualified health center network to determine the most effective and efficient approach to promote CRC screening in these settings. Results from the study, supplemented by cost analyses and the process evaluation will directly inform translational strategies for cancer prevention within difficult community-based healthcare settings.

Interventions

  • Behavioral: Physician Intervention
    • Physicians at these clinics will participate in 6 training sessions over the course of 3 1/2 years; training sessions relate to colorectal cancer (CRC) screening guidelines, communication skills, and health literacy training
  • Behavioral: Physician and Patient Intervention
    • Physicians at these clinics will participate in 6 training sessions over the course of 3 1/2 years; training sessions relate to colorectal cancer (CRC) screening guidelines, communication skills, and health literacy training; patients in this condition will also view an educational DVD on CRC and CRC screening

Arms, Groups and Cohorts

  • No Intervention: Control
    • Participants will complete interviewer-administered pre- and post-test
  • Experimental: Physician Intervention
    • Physicians at these clinics will participate in 6 training sessions over the course of 3 1/2 years; training sessions relate to colorectal cancer screening guidelines, communication skills, and health literacy training
  • Experimental: Physician and Patient Intervention
    • Physicians at these clinics will participate in 6 training sessions over the course of 3 1/2 years; training sessions relate to colorectal cancer (CRC) screening guidelines, communication skills, and health literacy training; patients in this condition will also view an educational digital video disc (DVD) on CRC and CRC screening

Clinical Trial Outcome Measures
