Patient-Provider Communication and Colorectal Cancer Screening Completion Using Multi-target Stool DNA Testing

Area of Science:

• Oncology
• Public Health
• Health Communication

Background:

• Colorectal cancer (CRC) screening is underutilized in the USA, despite available guideline-recommended options.
• Provider recommendations are crucial for improving CRC screening completion rates.

Purpose of the Study:

• To identify patient-provider communication factors associated with multi-target stool DNA (mt-sDNA) screening completion.
• To inform interventions aimed at increasing CRC screening adherence.

Main Methods:

• A behavioral theory-informed survey was administered to US adults aged 45-75 who received an order for mt-sDNA screening.
• Multivariable logistic regression analyzed communication factors linked to mt-sDNA test completion.
• Data collected from 2973 participants (21.7% response rate).

Main Results:

• 81.6% of participants discussed mt-sDNA testing with their provider before ordering.
• Conversations covering costs, follow-up, and instructions correlated with higher test completion and future use likelihood.
• Lack of discussion on screening options' pros/cons and limited patient involvement reduced completion odds.

Conclusions:

• Healthcare providers are pivotal in enhancing patient adherence to CRC screening.
• Providers need resources and training to effectively educate patients and facilitate shared decision-making in CRC screening choices.
