Project description:Interventions: Name of intervention: gender specific mail-administered screening invitation strategies.
All participants will receive an offer to participate in a free FOBT which will be delivered by mail. Intervention arms will differ from control according to the information included in the materials accompanying the screening offer. All study participants will receive a standard screening reminder irrespective of their intervention group. Intervention materials will target specific psychosocial variables previously identified as being related to male participation in FOBT screening.
The intervention period is 14 weeks. All participants will receive a screening offer according to the following timeline.
Baseline: Advance notification letter sent
Week two: Invitation package sent
Week eight: Reminder letters sent to those who have not completed an FOBT
Week 14: Data collection ceases.
Arm 1: Control
The control arm will receive a standard offer to participate in FOBT screening designed to mimic the strategy utilised by the Australian national bowel cancer screening program (NBCSP).
The standard offer includes an advance notification letter and a screening invitation package.
The advance notification letter is sent two weeks prior to the screening invitation package and is designed to alert participants that an invitation to screen for CRC with an FOBT will soon follow. The standard advance notification letter introduces basic information about colorectal cancer and the health benefits of screening.
The screening invitation package includes a) a screening invitation letter b) an immunochemical FOBT with associated instructions c) an information booklet that describes colorectal cancer and screening and d) a particip
Primary outcome(s): Rate of FOBT participation per trial arm as assessed by number of FOBT screening tests returned.[At 14 weeks from baseline, 12 weeks after receiving the FOBT.]

Project description:Interventions: The intervention is a bowel cancer screening program that includes the availability of a screening blood test after an offer of the standard faecal occult blood test (FOBT).
There are two intervention groups (n = 600 per group). Everyone in the intervention will be initially mailed an offer of screening for bowel cancer by FOBT. For the first intervention group, after 12 weeks anyone who has not participated with the FOBT will be mailed an offer of screening for bowel cancer by blood test (the methylated BCAT1/IKZF1 blood test). They will then need to call the study helpline to request a further blood test information.
The second intervention group will be sent the offer for the blood test at the same time as receiving the FOBT. They will be advised that if they believe that the FOBT is not suitable for them they might consider screening for bowel cancer by blood test. They will then need to call the study helpline to request a further blood test information.
Anyone requesting the blood test will then be sent information about the test (including accuracy of the test, where they can get their blood collected, and when they will receive their test results) and a test referral. They can then take up the offer of the free screening blood test at one of 10 local blood collection centres (Healthscope). They do not need to be fasted and appointments do not need to be made.
Reminder letters will be sent to non-participants 6 weeks after each type of screening test offer.
Participants of the FOBT will be required to collect a small sample from two separate bowel movements. These samples are then sent via reply-paid mail to a laboratory which tests the samples for the presence of blood. If more than 100ng/mL of blood is present in either sample,
Primary outcome(s): Total participation rate in a bowel cancer screening program that offers a FOBT followed by a blood test, compared to a program that only offers FOBT. This will be assessed at the 24 week timepoint by review of laboratory records.[24 weeks after the initial screening offer.]

Project description:The PICCOLINO is a randomized health services study performed within the framework of the Polish Colonoscopy Screening Program (PCSP) in Poland.
Within the study 12,298 eligible persons between 55 and 64 years of age will be drawn from the Population Registry and randomly assigned in a 1:1:1 ratio to receive an invitation to participate in one of the three screening strategies: (I) postal invitation to colonoscopy and a re-invitation to colonoscopy for initial non-responders, (II) postal invitation for screening using fecal immunochemical test (FIT) for non-responders and subjects refusing a colonoscopy, or (III) postal invitation offering a choice between FIT and colonoscopy.
Colonoscopies will be performed in seven local centers participating in the study. FITs will be analyzed in the central laboratory. Subjects with positive FIT result will be recommended to undergo colonoscopy.
The primary outcome is participation with CRC screening within 18 weeks after enrollment, defined as completion of colonoscopy, or completion of FIT along with colonoscopy for positive FIT result. Secondary outcome will be diagnostic yield for advanced neoplasia (CRC or advanced adenoma). The study has been approved by a local bioethics committee.

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
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.
