RCT of Automated Telephone Outreach to Improve Colorectal Cancer Screening

Colorectal Cancer Clinical Trial

Official title: Automated Telephone Outreach With Speech Recognition to Improve Colorectal Cancer Screening: A Randomized Controlled Trial

Status Completed

Clinical Trial Summary

This large randomized controlled trial is testing the effectiveness of automated telephone outreach with speech recognition to improve rates of screening for colorectal cancer. The hypothesis is that the intervention improves rates of screening overall and specifically rates of colonoscopy.

Clinical Trial Description

Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the United States. Despite widespread dissemination of evidence-based guidelines recommending CRC screening, a large proportion of eligible individuals do not undergo screening. A variety of interventions have been tested to increase screening in primary care, but there remains an urgent imperative to develop and evaluate cost-effective and widely applicable approaches to promoting screening. In March 2005, Harvard Pilgrim Health Care, a large non-profit HMO in New England, carried out an internally funded program to increase CRC screening. The HMO randomized 80,000 members aged 50 to 64 years to receive automated telephone outreach with speech recognition or usual care. The intervention entailed the telephone engagement of members in a dialogue with a computer-programmed, responsive human voice about the importance of CRC screening, the options for undergoing screening, and encouragement to follow-up with their primary care physicians. The present study involves a 12-month follow-up of all eligible members randomized to intervention or usual care in March 2005, with assessment of the effect of the intervention on rates of CRC screening. This study has important implications for increasing CRC screening. With health plans expanding efforts to screen large populations for CRC and other malignancies, automated telephone outreach with speech recognition can reach large numbers of individuals with educational and reminder messages. It is important to know whether these efforts to promote screening are effective in overcoming known disparities in screening for CRC. If proven effective and cost-effective, this technology has the potential for widespread adoption and population-wide improvements in CRC screening and other prevention-related behaviors, with the ultimate public health goal of reducing the burden of suffering attributable to cancer and its complications. ;
