Abstract

Screening for colorectal cancer is cost-effective, but many U.S. women are nonadherent, and the costeffectiveness of web-based tailored screening interventions is unknown. A randomized controlled trial, COBRA (Increasing Colorectal and Breast Cancer Screening), was the source of information for the economic evaluation. COBRA compared screening among a Usual Care group to: (i) tailored Phone Counseling intervention; (ii) tailored Web intervention; and (iii) tailored Web + Phone intervention groups. A sample of 1,196 women aged 50 to 75 who were nonadherent to colorectal cancer screening were recruited from Indiana primary care clinics during 2013 to 2015. Screening status was obtained through medical records at recruitment with verbal confirmation at consent, and at 6-month follow-up via medical record audit and participant self-report. A "best sample" analysis and microcosting from the patient and provider perspectives were applied to estimate the costs and effects of the interventions. Statistical uncertainty was analyzed with nonparametric bootstrapping and net benefit regression analysis. The per participant cost of implementing the Phone Counseling, Web-based, and Web + Phone Counseling interventions was $277, $314, and $336, respectively. The incremental cost per person screened for the Phone Counseling compared with no intervention was $995, while the additional cost of Web and theWeb + Phone compared with Phone Counseling did not yield additonal persons screened. Tailored Phone Counseling significantly increased colorectal cancer screening rates compared with Usual Care. Tailored Web interventions did not improve the screening rate compared with the lower cost Phone Counseling intervention.
