Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All eligible participants will receive an imunochemical faecal occult blood test (IFOBT) kit (EIKEN brand) containing the test and instructions, with additional explanation provided by study staff, as required. A sample is then collected from two separate bowel motions. All samples will be self-collected.

All completed kits will be sent and processed in a designated central laboratory and analysed according to the company’s standardised specifications. The results of this test can be positive, negative or inconclusive. All results will be sent via mail to the corresponding treating physicians, the participants and the research assistants at the Centre for Kidney Research. The screen is considered positive when one of the samples contains at least 50ng/ml of haemoglobin. Negative results are not followed up in the study but these patients are advised to continue with annual screening with their health practitioner. If the results are inconclusive, the participants will be contacted by phone and asked to repeat the test.

Only participants with positive IFOBT findings will be referred for a diagnostic colonoscopy at a designated colonoscopic service. Study staff will track participants with positive IFOBT results and will ensure the referral process is scheduled effectively and efficiently for a colonoscopy. The participants will not be required to pay for the IFOBT kit or the diagnostic colonoscopy. Other clinical significant pathologies such as polyps, adenomas, vascular lesions will be documented and recorded. Wherever possible, they will be resected and sent for pathology. Depending upon the stage of initial diagnosis, further treatment may be required for participants with malignant polyps and cancers. All cancer diagnoses, including stage, histological types, treatment effect, will be reported to the National Bowel Screening Program Register, the Central Cancer Registry of New South Wales (located within the Cancer Institute of NSW) and the Australian and New Zealand Dialysis and Transplant Registry (ANZDATA). Study staff will ensure the treatment plans and follow-up are taking place efficiently and effectively.

Comparator / control treatment
The reference standard should ideally be performed in all patients regardless of the screen test results and health status to avoid verification bias, but it would be medically and ethically unjustified to subject all patients (with and without positive screens) to receive the diagnostic colonoscopic procedure. Instead, all participants with positive screens, with or without a cancer, will be followed up clinically, with a phone-call for up to a period of 4 years. All negative FOBT screens will also be followed up clinically with a phone call, at the end of 2 and 4 years. For validation of such a procedure, we will also compare results of patients who had diagnostic colonoscopies and the standard diagnoses based upon clinical follow-up. To ensure adequate follow-up and accurate calculation of diagnostic test accuracies, we will compare our cancer records with that of the Central Cancer Registry of N.S.W. and the ANZDATA Registry. The ANZDATA Registry contains one of the largest and the most comprehensive databases of patients with renal replacement therapy in the world. The ANZDATA Registry collects all cancer records (stage, histological types and treatment) except for squamous and basal cell carcinomas of the skin.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients with chronic kidney disease in stages 3-5, dialysis or transplant populations will be recruited from the Sydney West Area Health Service. All eligible patients from each of these area health services will be identified and the researchers will consent the patients, if necessary, with a health care interpreter. All eligible participants will receive an IFOBT kit containing the test and instructions, with additional explanation provided by study staff, as required. All participants with positive IFOBT findings will be referred to a diagnostic colonoscopy at a designated colonoscopic service. Study staff will track participants with positive IFOBT results and will ensure the referral process is scheduled effectively and efficiently with no more than four weeks waiting time for a colonoscopy.
