Project description:Participation in a primary screening colonoscopy programs remains low. Advanced notification letter has been shown to increase participation in colorectal cancer screening with fecal occult blood testing and to be cost effective compared to standard invitation. It is unknown whether advanced notification letter increases participation rate in primary colonoscopy screening program.
We hypothesize that an Advance Notification Letter will have significant influence on participation in screening colonoscopy, comparing to standard invitation procedure and will thus result in higher efficiency of the program.
This randomized controlled study aims to compare the participation rate in screening colonoscopy in response to advanced notification plus standard invitation letter and standard invitation letter alone.
Material and methods: 6800 individuals aged 55-64 years will be drawn from the Population Registry and randomly assigned in a 1:1 ratio to the group invited for screening colonoscopy with advanced notification letter (send two weeks before standard invitation) plus standard invitation (send six weeks before planned screening colonoscopy) or to standard invitation only (send six weeks before planned screening colonoscopy). The sample size was calculated to detect 3% difference in participation rate between the groups (25% vs 28%) with 80% power.

Project description:Background and study aims
An advance notification letter conveying information on colorectal cancer (CRC) risk and the intervention offered in the screening programme, may increase the likelihood of a positive response to the subsequent screening invitation, as the subject will have progressed in his degree of readiness for change. In addition, it has been shown that, in particular for less educated subjects, general practitioners (GP) advice may have a strong influence on the decision to be screened. The study aims to assess the impact on the response rate to the invitation for CRC screening, in the context of population based programs, of an advance notification letter mailed to subjects eligible for invitation. The additional cost per person examined and the additional workload for the subjects GPs will be assessed.
Who can participate?
All subjects (male and female) aged 50 to 69 targeted for CRC screening in 8 population based programmes in Italy.
What does the study involve?
During the enrolment period all subjects targeted for invitation in these screening programs were randomly allocated to three groups:
A: standard personal invitation letter, signed by the GP, to undergo CRC screening
B: advance notification letter, mailed one month before the standard invitation letter (same as in A), conveying information on CRC risk, on the screening program and on the expected benefits and potential harms of screening
C: as in B, with the addition, in the advance notification letter, of the offer of a personal encounter with the subjects GP, to discuss pros and cons of screening. The response rate across the different groups will be assessed at 6 months following the invitation letter.

Project description:Interventions: Group 1: Circular of the respective health insurance companies at their 50-54 years old insured persons. Besides the information about the offer of screening colonoscopy from the age of 50 and the invitation to its awareness, the letter contains a one-minute risk self-check for colorectal cancer (intervention group).
Group 2: Circular of the respective health insurance companies at their 50-54 years insured persons. The letter includes information about the offer of screening colonoscopy from the age of 50 and invitation to its awareness. The letter does not contain a one-minute risk self-check for colorectal cancer (control group).
Primary outcome(s): Increase of colorectal neoplasm detection rates through an invitation letter containing a risk self-check compared to an invitation letter without risk self-check.
Study Design: Allocation: Randomized controlled study; Masking: Blinded (masking used); Control: Other; Assignment: other; Study design purpose: prevention

Project description:The attendance rate to population based primary screening colonoscopy within NordICC trial (The Nordic-European Initiative on Colorectal Cancer, NCT00883792) in Poland is roughly 33%. The aim of this study is to compare the effect of two different time schedules for sending invitations and reminding letters to a pre-specified colonoscopy appointment. 1,600 screening naive men and women 55 to 64 years of age are randomly assigned in a 1:1 ratio to receive invitation and reminder 6 and 3 weeks (SIX and THREE group) or 4 and 2 weeks (FOUR and TWO group) prior to pre-specified screening colonoscopy appointment date. Outcome measures are participation in screening colonoscopy within 6 months from the date of invitation, response and acceptance rate before sending a reminder. The study is powered to detect 7% difference in participation in screening colonoscopy.

Project description:The investigators hope to determine whether the addition of an FOBT kit and educational materials to a second mailed invitation compared to a second mailed invitation alone increases use of appropriate screening tests (FOBT for average risk or colonoscopy if increased risk) by eligible persons within 6 months of the second mailing in: (1)Non-responders to an initial mailed CRC screening invitation from their family physician and, (2)Those who responded to the initial mailed CRC screening invitation and are due for repeat screening (i.e., "recall" patients). In addition, the investigators will also explore the impact of the investigators intervention in likely under-screened groups such as those living in more remote areas of the province and those with low socio-economic status as well as assessing the cost-effectiveness of this strategy.

Project description:Background and study aims
While colorectal cancer (CRC) screening can detect cancer at an early stage, participation in CRC screening programmes is often below recommended levels. In order to be effective, CRC screening programs high participation. There is therefore an interest in studying possible interventions to achieve high participation. While interventions such as pre-notification letters, tailored reminder letters and telephone contact can increase participation, they are often too costly for the screening programmes. Interventions based on behavioural economics only manipulate the decision setting and are therefore potentially cost-neutral. The aim of this study is to test whether messages derived from behavioral economics can increase participation in the context of the Cypriot pilot program for colorectal cancer screening.
Who can participate?
All residents aged 50-69 years who are eligible for colorectal cancer screening.
What does the study involve?
In the first study participants are randomly allocated to receive the standard invitation letter with one of six additional behavioral economics-based messages included, or the standard invitation letter with no manipulation. The additional behavioural economics-based messages are built on the following principles: (1) social responsibility to look after own health, (2) anticipated regret of non-attendance, (3) financial opportunity costs of non-attendance, (4) benefit of early detection, (5) limited duration of the offer and (6) social norms. In the second study participants are randomly allocated to receive either the standard invitation letter with the most effective message from the first study, or the standard invitation letter with no manipulation.

Project description:Participants will be mailed an invitation to complete CRC screening along with a fecal immunochemical test (FIT) kit, containing a 1-sample "Polymedco Over the Counter (OC) Sensor FIT", simplified English/Spanish instructions on performing the test, educational information about colorectal cancer screening and a return mailer with prepaid postage.
Processes that will be used to promote screening completion include automated and "live" phone call reminders to encourage completion of FIT testing.
Participants will be randomly assigned to 1 of 5 interventions across 3 conditions, described below:
1. Condition 1 (Standard Intervention):
* Branch I: Participants assigned to the control condition will receive a FIT kit and the standard invitation letter to participate in free screening.
2. Condition 2 (Time Guideline):
* Branch II: Participants will receive a FIT kit and invitation letter to participate in free screening with a 1-week time restriction.
* Branch III: Participants will receive a FIT kit and invitation letter to participate in free screening with a 3-week time restriction.
3. Condition 3 (Time Guideline + Incentive):
* Branch IV: Participants will receive a FIT kit and invitation letter to participate in free screening requesting they return the kit within 1-week for a "higher" monetary incentive or within 3 weeks for a "lower" (half of the higher) monetary incentive.
* Branch V: Participants will receive a FIT kit and invitation letter to participate in free screening requesting they return the kit within 1-week for a "higher" (same as lower in Branch IV) monetary incentive or within 3 weeks for a "lower" (half of the higher) monetary incentive.
Participants with a normal test result will receive a personal letter confirming this with invitations to complete a repeat screening in subsequent year(s). Participants receiving an abnormal FIT result will be navigated to complete a diagnostic colonoscopy.
Participants continuing in the screening program in subsequent years will receive letters emphasizing the importance of repeat screening to prevent adverse CRC outcomes.
