Impact of a promotional DVD on bowel screening uptake for

INTERVENTION: A six minute promotional DVD is currently being introduced in the Waitemata DHB bowel screening pilot. The DVD is being offered in addition to usual care. ). Usual care is a standard reminder letter, and for priority groups (Maori, Pacific and Asian), also a phone call follow‐up from a culturally appropriate outreach co‐ordinator located in the bowel screening pilot. The Data Manager estimates that approximately 50% of priority group participants are able to be reached with 3x phone follow up attempts. There will be no change to usual care for any participant group. The DVD shows a well known local Maori couple (kaumatua Pio and whaea Chrissy Jacobs) telling the story of whaea Chrissy’s recent experience of bowel screening, and being screened positive (having a positive test followed by a colonoscopy). The DVD is narrated by ex‐All Black Frano Botica, and includes a small amount of educational commentary on how to participate in bowel screening, and how to return the test kit (for example labelling and postage details). The DVD is intended to be watched in participant's own home, in their own time, when it is convenient for them, on their own DVD playing equipment. The DVD was designed by the Community Awareness Raising team in the bowel screening pilot to be a culturally appropriate for Maori. The DVD was developed with the intention to promote bowel screening and to motivate invitees to participate by returning their test kits. The study will run for approximately a year (calculated on the number of Maori and Pacific people to be invited in the remainder of the current screening round), in order to reach the numbers suggested by the power calculation (4600 ‐ 2600 Maori and 2000 Pacific). CONDITION: Participation in a bowel screening pilot PRIMARY OUTCOME: Difference in uptake between those who receive the DVD and those who do not. ; ; The bowel screening pilot involves self‐testing faecal matter in the participants own home with the supplied test kit, sealing the kit as instructed, labelling it (including barcode), signing the consent form and returning the kit in the supplied sealed bag in the post direct to the laboratory. ; ; Uptake as an outcome in this study refers to participation in the bowel screening pilot by return of the test kit. The purpose of the reminder letter (and the DVD as an intervention at this point) is to encourage people to participate in bowel screening. ; ; Uptake (or participation) is routinely measured in the bowel screening pilot, when a kit is received by the laboratory. It is measured at 4 weeks post invitation in order to generate a list of those who have not responded to be followed‐up (as part of usual care) with a reminder letter and phone calls (for priority groups). Uptake is then measured continuously after that; no further reminders are sent by participants are able to send their test kit in to be analysed at any time after their reminder letter. ; ; For the purposes of this study the Data Manager has been asked to provide the researchers the proportion of test kits returned (the uptake) at 6 weeks post reminder. SECONDARY OUTCOME: Difference in the rate of spoiled kits returned between those who receive the DVD and those who do not. Spoiled kits are those with labelling or collection issues affecting the ability for the laboratory to process the sample. INCLUSION CRITERIA: 1. Bowel screening pilot invitees (male or female Waitemata DHB residents aged 50‐69 year old, who are eligible for publically funded healthcare). 2. Non responders to the initial invitation at four weeks 3. Maori or Pacific
