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: Two alternative advance notification strategies will be trialed. Intervention 1 will consist of a simple ‘advance notification of an invitation to participate in screening for Colorectal Carcinoma (CRC)’ letter incorporating messages introducing the concept of screening for CRC, increased risk for CRC and the value of screening to reduce risk. Intervention 2 (enhanced advance notification) will include those messages plus more complex messages to reduce known barriers (lack of knowledge about CRC and its prevention, aversion for faecal sampling, low perception of the value of Fecal Occult Blood Test (FOBT) screening). The advance notification letters will be followed in 2 weeks by a standard invitation-to-screen letter. A control group will receive the standard invitation only. Invitees have 12 weeks from date of invitation-to-screen in which to participate in screening.
Primary outcome(s): Completion of faecal immunochemical test expressed as the population participation rate.[Within 12 weeks of screening invitation.]

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: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:The aim of this project is to assess the impact on health and economics of the implementation of text messaging (SMS) in cancer screening programs. Three interventions with SMS will be evaluated through community trials. In the colorectal cancer screening program the following interventions will be tested: a) Participation reminder: six weeks after sending the invitation letter of the colorectal cancer program if there has not been a response, a reminder SMS will be sent in front of the usual method by letter; b) Reminder to return the fecal occult blood test: SMS reminder of test delivery versus no intervention. This reminder will be sent to the individuals who have gone to the pharmacy to pick up a fecal occult blood test and they have not returned it after 14 days. The impact on participation will be analyzed and, if applicable, the proportion of advanced neoplasms will be calculated by increase in participation. In the breast cancer screening program, the invitation by SMS versus the usual invitation by letter will be studied in women who had participated in the previous screening round. The impact on participation will be analyzed. A cost-effectiveness analysis of the three interventions will be carried out. The incremental cost ratio of the interventions between cost variation and effectiveness variation will be calculated.

Project description:Interventions: Group 1: Focus of the letter/writing addressed to the 50 year old group (two intervention groups of the birth year 1962) is testing for occult blood in the stool, which is paid by the health insurance from that age (and up to 55 years) annually. Beside the information about this offer and the invitation to its perception, the letter/writing should contain an understandable and clear information booklet about the test and its application and significance. In one of the two intervention groups, a stool test kit for carrying out the tests for blood in the stool should be additionally attached (test cards for each two samples from three consecutive bowel movements). It should be checked whether this service offer further increases participation rate in Germany, as shown in other countries. People in the intervention group 2 (cover letter with the stool test kit) will be asked to apply the test cards and send them to the DKFZ. There, the tests will be analysed and the result will be reported directly by mail to the persons and, if desired, additionally to the family doctor of whom the address is reported on a request form. In case of a positive test result, a meeting is recommended with the family doctor to discuss the possibility of a colonoscopic investigation. The test results are pseudonymised forwarded to the study center in the Saarland, where they can be clearly assigned to the investigation group 2 based on the communication numbers (which are noted on the materials sent to them). To check the benefits of repeated letters/writing of the same birth cohort, people are contacted again on the following 51th birthday (regardless of participation in the previous year). For this purpose there is a re-randomization, regardless of the assignment to the intervention and cont
Primary aims of the pilot project are the detection and quantification of the increase in participation rate in colorectal cancer early detection through a logistic uncomplex personal invitation procedure. The issues include in particular:
- To what extent can the use of the test for occult blood in the stool be increased through a personal invitation letter with an information booklet?
- To what extend can the sending of a stool test kit together with the personal invitation letter further increase participation?
- To what extend is a colonoscopy performed in case of a positive test result?
- To what extend can the use of screening colonoscopy be increased through a personal invitation letter with an information booklet?
- What effects can be achieved in terms of participation at initial cover letter and follow-up letter in one year distance?
- For all questions: Are there differences between women and men?

Project description:Interventions: Eligible people (n = 240) within the SCOOP program (a colonoscopy surveillance program for individuals at higher risk for bowel cancer) at Repatriation General Hospital or Flinders Medical Centre who do not screen for bowel cancer via the standard means (ie. faecal testing), will be sent a letter to invite them to screen for bowel cancer with a blood test (Colovantage Plasma), as well as a short survey to ascertain their demographic details and their screening history. Anyone interested in taking up the blood screening test will be asked to fill in the consent form and request form and send them back (in the provided reply paid envelope) to the Bowel Health Service. Following receipt of the blood test request form, the study enrolee will then be sent further information on the blood test (including information on the 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 four 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 after 6 weeks to those people who have not taken up the blood test screening offer. Screening participation rate with the blood test and demographic factors that influence uptake, will be assessed at the 12 week time point.
Primary outcome(s): The primary outcome is to determine how many people within 12 weeks following the invitation letter have a blood sample collected for bowel cancer screening (ie. outcome = blood test participation rate). The number that complete the blood test will be expressed as a percentage of the invited cohort (ie. 240)[12 weeks after invitation to screen.];An additional primary outcome will be to determine the factors that predict screening uptake with the blood test, ie. age, gender, risk status for bowel cancer, reasons for not participating with faecal testing. This information will be established via a short survey (designed specifically for this study) that is provided with the original study invitation letter.[12 weeks after invitation to screen.]

Project description:The effect of mailing FIT with the invitation on participation and colonoscopy rates will be evaluated in a randomized controlled trial conducted in the Centre-Val de Loire (CVL) region, involving 64,000 people from the population eligible for colorectal cancer population-based organised screening program (CRC-PBOSP).
In the "C" control group, invitations, test delivery and reminders will be carried out in accordance with the CRC-PBOSP rules at the time of the study.
Intervention group "B" will evaluate two experimental modes of invitation with direct home mailing of the test:
* Method "B1": invitation with test sent to home without prior information letter
* Method "B2": information letter followed by invitation with test sent home, designed to optimize participation by first-time subjects (aged 50-51) invited to the CRC-PBOSP for the first time.
Ancillary studies will focus 1/ on acceptability of this intervention (qualitative study on a few general practitioners, gastroenterologists and invitees), 2/ on social and geographical inequalities of participation on a subsample of individuals included in EXPEDIT study using ecological indices (EDI, SCALE).
