Decreasing colorectal cancer screening disparities: A culturally tailored patient navigation program for Hispanic patients.

Abstract

Colorectal cancer (CRC) is the second leading cause of cancer-related death in Hispanic patients. Screening colonoscopy has been shown to reduce the incidence and mortality of CRC. However, utilization among Hispanic patients and other minority groups is low. The objective of this study was to evaluate colonoscopy utilization among Hispanic patients with a culturally tailored patient navigation program (CTPNP) in place. A CTPNP was designed to meet the needs of the authors' Hispanic patient population and their health care system characteristics. A CTPNP protocol was created, and a Spanish-speaking navigator/coordinator was hired. Enrolled patients received a Spanish-language introductory letter, an initial phone call for patient education, and follow-up calls to ensure that all potential barriers to colonoscopy were overcome. Colonoscopy completion (CC), colonoscopy cancellation (CN), and colonoscopy no-show (NS) rates were recorded and compared with historical rates in Rhode Island. Over a 28-month period, 773 patients were referred to the CTPNP, and 698 (53% female and 47% male) were enrolled in the program. The overall CC rate was 85% (n=592) with no difference between males and females. The CN rate was 9% (n=62), and the NS rate was 6% (n=44). The most common reasons for CN and NS were cost and an inability to contact the patient after referral. Within the CC group, 43% (n=254) of patients underwent polypectomy, and 1.3% (n=8) required colectomy. Ninety percent (n=530) of the CC group reported that they would not have completed colonoscopy without the CTPNP. Implementation of a CTPNP is an effective intervention to improve the CC rate and eliminate the historical gender gap in utilization among Hispanic patients.
