What do patients and doctors think about alternative bowel screening strategies for people needing colonoscopy?

ABSTRACT: Interventions: This study will use surveys to determine the acceptability of faecal and blood-based bowel screening strategies for triaging individuals with a higher than average risk of colorectal cancer (CRC) to colonoscopy. This will include individuals requiring colonoscopy in response to abnormal gastrointestinal symptoms, a significant family history of CRC, and/or a previous finding of polyps. Individuals invited into the study will be patients who are scheduled to undergo a colonoscopy due to one of these risk factors, and clinicians who are involved in the care of people undergoing colonoscopy. Individuals who are scheduled to undergo a colonoscopy for gastrointestinal symptoms or CRC surveillance at one of the approved study sites (Flinders Medical Centre, Noarlunga Health Service, Tennyson Centre Day Hospital, Queen Elizabeth Hospital) will be identified via clinic and colonoscopy booking lists for invitation into the study. A letter will be sent to eligible participants approximately 2-4 weeks prior to their scheduled colonoscopy to invite them to complete a survey before their procedure. All respondents to this initial survey will be invited to complete a follow-up survey approximately one month after their colonoscopy. Participants will have the option to complete the surveys online (via a link or by scanning a QR code) or through a paper copy sent to them along with a reply-paid envelope. Each survey will take approximately 20-30 minutes to complete and will measure the acceptability of different bowel screening methods along with the following variables: previous clinical testing experiences and knowledge, health beliefs, health literacy, health-related quality of life, and fear of bowel cancer. Clinicians will be invited to complete a single online Primary outcome(s): A primary outcome for colonoscopy consumers will be their acceptability of faecal-based bowel screening tests for use in determining their need for colonoscopy. This will be assessed within the pre- and post-colonoscopy surveys using items that have been designed specifically for this study.

Project description:Interventions: We propose to conduct a prospective observational study to investigate how change in diet and lifestyle patterns over time impacts the development of precancerous colorectal lesions or colorectal cancer in individuals at above average risk of colorectal cancer and undergoing a colonoscopy surveillance - the ‘Southern Cooperative Program for the prevention of colorectal cancer’ (SCOOP). Data regarding patients’ colonoscopies will be extracted from the SCOOP database. Participants enrolled in the SCOOP program will be invited to complete the diet and lifestyle survey over the period of three years (in years 1 (baseline survey), 2 and 3 (follow-up surveys)). The survey can be completed by the participants either online, by clicking on a provided link or scanning a QR code. It is expected that each survey will require around 40-50 minutes to be filled out. The exposure variables include: -Dietary intake (using a validated food frequency questionnaire from the Australian Eating Survey), -Physical activity (using the International Physical Activity Questionnaire (IPAQ-L)), -Sleep patterns (Pittsburgh Sleep Quality Index (PSQI), Obstructive sleep apnoea screening questionnaire (OSAS), and Insomnia Severity Index questionnaire, -Smoking status, -Body mass index (BMI), -Aspirin intake, and -Comorbidities including diabetes. Primary outcome(s): The primary outcome of this study will be the dietary pattern that will be assessed using a validated food frequency questionnaire. [This will be assessed at baseline (year 1), years 2 and 3 at anytime during the three year observation period. Individuals whose colonoscopies are due within one year will receive only one diet survey (baseline), while those whose colonoscopies are due in two years’ time will receive only two diet surveys before their next scheduled colonoscopy. Most patients under surveillance will receive regular colonoscopies at intervals of 3 or 5 years, and they will be able to take part in all three diet surveys until the next scheduled colonoscopy.];Another primary outcome of this study will be sleep quality assessed by a validated International Physical Activity Questionnaire (IPAQ-L).

Project description:Interventions: Over recent years there has been an increase in the development of new blood tests for the use in detection, monitoring and surveillance of cancers. It is important that acceptability to cancer surveillance with blood biomarkers is identified through a range of approaches. This research will use focus groups to identify acceptability of blood biomarker tests, as well as other methods such as CT scans and colonoscopy, for use in cancer surveillance. This will be done with: (1) people who have undergone treatment for the different cancers (oesophageal, stomach or bowel), (2) their carers or support persons, and (3) clinicians who are involved in cancer treatment. Individuals who have undergone treatment for oesophageal, stomach, or bowel cancer during the prior three years will be identified via the gastrointestinal cancer clinic lists at the Flinders Medical Centre for invitation into a focus group, along with their nominated support person. Clinicians will be invited into the focus groups through an information session or email. Prior to the focus group, consented individuals will be contacted by a member of the research team to collect baseline characteristics (e.g., demographics, details about cancer stage and treatment, roles covered as a support person or clinician). Focus groups will be held in person at Flinders Centre for Innovation in Cancer, Bedford Park, South Australia, or via a web-based option such as Zoom or Microsoft TEAMS. The focus group will take approximately 45 minutes and each participant will only participate in one focus group. Separate focus groups will be held for patients, carers and clinicians, with approximately 6 people invited into each session. The focus groups will be led by facilitators (study researchers) who will follow a sem Primary outcome(s): Knowledge of clinical tests to monitor cancer treatment and surveillance, which will be assessed using qualitative, audio recorded, 45-minute focus group discussions which will be semi-structured based upon a study-specific discussion guide.[1 month after recruitment (during the focus group)];Trust in clinical tests to monitor cancer treatment and surveillance, which will be assessed using qualitative, audio recorded, 45-minute focus group discussions which will be semi-structured based upon a study-specific discussion guide.[1 month after recruitment (during the focus group)];Experience of clinical tests to monitor cancer treatment and surveillance, which will be assessed using qualitative, audio recorded, 45-minute focus group discussions which will be semi-structured based upon a study-specific discussion guide.[1 month after recruitment (during the focus group)] Study Design: Purpose: Psychosocial;Duration: Cross-sectional;Selection: Defined population;Timing: Prospective
