Bundled Cancer Screening and Genetic Services Navigation

Research Design and Methods:

All women referred for screening navigation within community navigation programs receive familial cancer risk assessment, bundled with either multicancer (colorectal + breast) vs. single (breast) cancer navigation, with a wait list control for colorectal cancer screening referral and navigation, stratified by site and genetics referral eligibility. Primary analyses will be conducted among those randomized to multicancer or single cancer navigation, but ineligible for genetic referral, to test effectiveness for colorectal cancer screening and non-inferiority for breast cancer screening (N=600). In exploratory subanalyses among those referred to genetic counseling based on their familial cancer risk assessment, the study will test the effect of four bundles that combine multicancer vs. single cancer navigation with usual care referral to telephone-based pretest and posttest genetic counseling and testing or video and print pre-counseling education + referral (N=180). A multi-site, mixed-methods organization- and patient-focused process evaluation is conducted alongside and at the conclusion of the trial.

Research Procedures:

Research staff not associated with navigation programs will obtain consent and HIPAA authorization, proceeding with baseline assessment and randomization, stratified by site and genetics eligibility. The trial will recruit (N=820) and retain (N=780) women to this trial within two years. N=600 are retained for primary analyses; N=180 are retained for exploratory outcomes among those referred to genetic services.

Randomization. At the end of the baseline assessment, research staff randomize participants to the single or multicancer navigation conditions, stratified by navigation site and genetic testing eligibility. Participants will be notified of study condition and connected to a navigator. Participants eligible for genetic services will receive services related to their study arm from their navigator following completion of multicancer or single cancer screening navigation. This will result in four bundles of screening and genetic services to be assessed in exploratory analyses. Contamination is mitigated through navigator training and supervision and documentation tracking. Participants will be randomized in blocks of 4 or 6 to support equal sample sizes across arms.
