Doctor suggestions for surveillance colonoscopies in older adults with prior adenomas range based mostly on a number of elements, together with affected person age, well being, adenoma threat, and doctor specialty, in keeping with a nationwide survey.
Typically, physicians had been extra prone to advocate surveillance for sufferers at a youthful age, with higher well being, and with prior high-risk adenomas. Moreover, a big proportion of physicians reported uncertainty about whether or not the advantages of continued surveillance outweighed the danger of hurt in older adults.

“There aren’t any current surveillance colonoscopy pointers that combine affected person age, well being, and adenoma threat, and physicians report vital decisional uncertainty,” write Nancy Schoenborn, MD, MHS, affiliate professor of medication at Johns Hopkins College Faculty of Drugs in Baltimore, Maryland, and colleagues.
“Growing the proof base to judge the dangers and advantages of surveillance colonoscopy in older adults, and decisional help instruments that assist physicians and sufferers incorporate out there knowledge and weigh dangers and advantages are wanted to handle present gaps in look after older adults with prior adenomas,” the authors write.
The examine was revealed on-line final month within the American Journal of Gastroenterology.
Surveying Physicians
Nationwide pointers advocate surveillance colonoscopy after adenoma elimination at extra frequent intervals than screening colonoscopy due to a better threat of colorectal most cancers amongst sufferers with adenomas. The top quality of screening colonoscopies coupled with an getting older inhabitants implies that many older adults have a historical past of adenomas and proceed to endure surveillance colonoscopies, the authors write.
The profit–hurt steadiness turns into unsure as potential harms from the process improve with age. Nonetheless, there isn’t any clear steering on when to cease surveillance in older adults following adenoma detection, they write.
Schoenborn and colleagues carried out a nationwide cross-sectional survey of 1800 main care physicians and 600 gastroenterologists between April and November 2021. The first care group included inner medication, household medication, basic follow, and geriatric medication physicians.
The analysis group requested whether or not physicians would advocate surveillance colonoscopy in a sequence of 12 vignettes that diversified by affected person age (75 or 85), affected person well being (good, medium, or poor), and prior adenoma threat (low or excessive).
Good well being was described as “well-controlled hypertension; residing independently,” whereas average well being was described as “average congestive coronary heart failure; has issue strolling” and poor well being was described as “extreme COPD [chronic obstructive pulmonary disease] on oxygen; requires assist with self-care.”
For prior adenomas, excessive threat concerned 5 tubular adenomas, one in all which was 15 mm, and low threat concerned two tubular adenomas, each of which had been lower than 10 mm. The survey additionally famous that the beneficial surveillance intervals had been 3 years within the high-risk state of affairs and seven years within the low-risk state of affairs.
Researchers mailed 2400 surveys and obtained 1040 responses. They included 874 within the evaluation as a result of the doctor respondents offered care to sufferers ages 65 and older and hung out seeing sufferers in clinic. Selections about surveillance colonoscopies for adenomas within the absence of signs nearly all the time happen within the outpatient setting, somewhat than acute or pressing care, the authors write.
Massive Variations Discovered
Total, physicians had been much less prone to advocate surveillance colonoscopies if the affected person was older, had poor well being, and had lower-risk adenomas. Affected person age and well being had bigger results on decision-making than adenoma threat, with well being standing having the most important impact.
About 20.6% of physicians beneficial surveillance if the affected person was 85, in contrast with 49.8% if the affected person was 75. As well as, 7.1% of physicians beneficial surveillance if the affected person was ill, in contrast with 28.8% for these in average well being, and 67.7% for sufferers in good well being.
If the prior adenoma was low threat, 29.7% of physicians beneficial surveillance, in contrast with 41.6% if the prior adenoma was excessive threat.
Typically, household medication and basic follow physicians had been more than likely to advocate surveillance, at 40%, and gastroenterologists had been least prone to advocate surveillance, at 30.9%. Affected person age and well being had bigger results amongst gastroenterologists than amongst main care physicians, and adenoma threat had comparable results between the 2 teams.
“The significance of affected person age and well being standing present in our examine mirrors examine outcomes on doctor decision-making relating to screening colonoscopies in older adults and makes intuitive sense,” the authors write. “Whether or not the priorities mirrored in our findings are supported by proof isn’t clear, and our outcomes spotlight essential information gaps within the area that warrant future analysis.”
Doctor Uncertainty
Further steering can be useful, the authors write. Within the survey, about 52.3% of main care physicians and 35.4% of gastroenterologists reported uncertainty concerning the profit–hurt steadiness of surveillance in older adults.
“Present pointers on surveillance colonoscopies are solely based mostly on prior adenoma traits,” the authors write. “Tips want to include steering that considers affected person age and well being standing, in addition to adenoma threat, and explicitly considers when surveillance ought to cease in older adults.”
As well as, most physicians within the survey — 85.9% of main care physicians and 77% of gastroenterologists — stated they might discover a determination help software useful. On the similar time, 32.8% of main care physicians and 71.5% of gastroenterologists perceived it because the gastroenterologist’s function to resolve about surveillance colonoscopies.
“Growing patient-facing supplies, communication instruments for clinicians, and instruments to help shared decision-making about surveillance colonoscopies that interact each physicians and sufferers are all essential subsequent steps,” the authors write. “To our information, there isn’t any current affected person determination help about surveillance colonoscopies; growing such a software could also be helpful.”
The examine was supported by Dr Schoenborn’s profession improvement award from the Nationwide Institute on Growing older. The authors reported no conflicts of curiosity.
