Official title
Impact of an Implementation Intention Planning Guide on Fecal Immunochemical Tests (FIT) Completion Rates
Overview
Fecal immunochemical tests (FIT) are a primary method of screening for colorectal cancer (CRC). Implementation intention planning involves encouraging completion or eliminating barriers for the participant to make a plan to complete a behavior or activity. This randomized control study seeks to answer whether the addition of an implementation intention guide impacts behaviors when completing FIT screening. The primary objective includes determining if the implementation intention guide increases completion rate of screening FIT. The secondary objectives is whether this intervention decreases the lab sample rejection rate and reduces the duration between sample collection and laboratory receipt/evaluation of screening FIT.
Detailed description
Colorectal cancer (CRC) has a high incidence, burden of disease, and significant associated mortality.(1,2) Programs to screen for CRC have leveraged stool testing with the fecal immunochemical test (FIT), a non-invasive at home test with no inherent risks, as the primary method in many countries.(3) Advantages of screening with FIT include considerations of safety, simplicity, and cost. However, while this and other options are available for colorectal cancer screening, patient screening rates have still not achieved recommended 70-80% targets.(4) In order to increase colorectal cancer screening rates, various behavioral interventions (including screening reminders, mailed screening outreach, choice architecture) have been implemented with success.(5,6)
Implementation intention planning involves encouraging or eliminating barriers for the participant to make a plan and complete FIT. Prior examples found that touchscreen implementation intention planning increased CRC screening completion by 12%.(7) For FOBT specifically, implementation intention planning instructions increased completion by 1.2-6.6%.(8) However, pre-written tips about FIT related to barriers did not increase FIT completion.(9)
This study seeks to understand the impact of a simple implementation intention planning guide (one-page piece of paper) on increasing rates of successful completion of FIT for colorectal cancer screening. The implementation intention planning guide is a one-page document that encourages the patient to make concrete plans about completing FIT. This study will evaluate if this low-cost intervention improves the rate of successful completion and reduces the duration between sample collection and lab result.
While some versions of implementation intention planning for CRC screening have been evaluated and shown positive impact in CRC screening completion, this study is hoping to build on these findings to evaluate a simplified implementation intention guide for patients specific to FIT. If this intervention is found to improve completion, these significant findings would support future FIT programs with a simple intervention to improve community screening rates. If these interventions do not improve completion, this research will inform the need to pursue investment in evaluating other interventions to improve FIT screening rates.
Aim 1: To determine if inclusion of implementation intention guide in FIT increases 90-day completion rate of screening FIT.
Hypothesis 1: The inclusion of implementation intention guide in FIT will increase the 90-day completion rate of screening FIT by 7%.
Aim 2: To determine if inclusion of implementation intention guide with FIT reduces the duration between sample collection and laboratory receipt/evaluation of screening FIT.
Hypothesis 2: The inclusion of implementation intention guide in FIT will reduce the duration between sample collection and laboratory receipt/evaluation by 20% in number of days and increase the number of samples received in the clinically appropriate time window of screening FIT (reducing the sample rejection rate) by 20%.

Interventions
- Behavioral Implementation Intention Guide
The intervention is the addition of implementation intention guide document provided with the FIT. This is a one-page piece of paper that was developed by the investigator team and finalized with input/feedback from patient partners. The implementation intention guide includes instructions about the importance of developing a plan to complete FIT. It also includes fillable fields for participants to enter their plan for when to complete, where to store, when to return, and where to return their
Primary outcome measures
- FIT completion rate [Time frame: Through study completion, approximately 12-18 months]
Secondary outcome measures (2)
- Duration between FIT collection date and receipt by the laboratory [Time frame: Through study completion, approximately 12-18 months]
- Rate of lab sample rejection [Time frame: Through study completion, approximately 12-18 months]
