NICE 24th August 2023
Tens of thousands of people a year could be spared the need for a colonoscopy following new guidance from NICE.
People with signs or symptoms of colorectal cancer should be offered a home test with quantitative faecal immunochemical tests (FIT) from 1 of 2 technologies (HM-JACKarc or OC-Sensor). This could lead to faster diagnosis, with fewer people referred to secondary care for an unnecessary colonoscopy. People who require follow up investigation can then be prioritised for referral leading to colonoscopy services focusing on those people who need them most.
Analysis carried out by NICE shows if there is a 25% reduction in the number of people referred, 94,291 fewer colonoscopies would take place.
North Tees and Hartlepool NHS Foundation Trust is already using the approach recommended by NICE and found they detected more cancers using fewer colonoscopies, which is better for patients and more efficient for the NHS.
NICE’s diagnostic advisory committee has recommended a sample is sent in the post to a laboratory where the amount of blood in the faeces is measured. The results are usually available within a week and people with 10 or more micrograms of haemoglobin in their faeces should then be referred for further investigation.
Under previous NICE guidance, FIT was already offered to some people presenting to primary care with symptoms suggestive of colorectal cancer, while others were immediately referred on the suspected cancer pathway.
Further assessment using colonoscopy, or CT colonography, is required to diagnose cancer.
Colonoscopy capacity is limited, and there are sometimes long wait times. Using FIT could reduce the number of people referred for urgent colonoscopy, and so reduce the waiting times to allow people on non-urgent referral pathways to be seen more quickly. For people where there is strong clinical concern of cancer because of ongoing unexplained symptoms, the guidance remains to refer them immediately to secondary care.
