Evaluation of a 2-1-1 Telephone Navigation Program to increase Cancer Control Behaviors: Results From a Randomized Controlled Trial

PURPOSE: to evaluate the effectiveness of a telephone navigation intervention for increasing use of cancer control services among underserved 2-1-1 callers. DESIGN: Randomized controlled trial. SETTING: 2-1-1 call centers in Houston and Weslaco, Texas (located in the Rio Grande Valley near the Mexican border). PARTICIPANTS: 2-1-1 callers in need of Pap test, mammography, colorectal cancer screening, smoking cessation counseling, and/or HPV vaccination for a daughter (n = 1,554). A majority were low-income and described themselves as Black or Hispanic. INTERVENTION: Participants were randomly assigned to receive either a cancer control referral for the needed service(s) with telephone navigation from a trained cancer control navigator (n = 995) or a referral only (n = 559). MEASURES: Uptake of each individual service and any needed service. ANALYSIS: Assessed uptake in both groups using bivariate chi-square analyses and multivariable logistic regression analyses, adjusted for sociodemographic covariates. Both per-protocol and intent-to-treat approaches were used. RESULTS: Both interventions increased cancer control behaviors. Referral with navigation intervention resulted in significantly greater completion of any needed service (OR = 1.38; p = .042), Pap test (OR = 1.56; p = .023), and smoking cessation counseling (OR = 2.66; p = .044), than referral-only condition. Other outcomes showed the same trend although the difference was not statistically significant: mammography (OR = 1.53; p = .106); colorectal cancer screening (OR = 1.80; p = .095); and HPV vaccination of a daughter (OR = 1.61; p = .331). CONCLUSION: Adding cancer control referrals and navigation to an informational service like the 2-1-1 program can increase overall participation in cancer control services
