A Mayo Clinic study has reported that colorectal cancer screening preferences of primary care clinicians shifted toward non-invasive options in general and particularly for patients who were unwilling to undergo invasive procedures.
"Nearly one-third of eligible adults in the US are not up to date on colorectal cancer screening, and even lower rates have been observed among populations that are traditionally underserved," said Dr Lila Rutten, a health services researcher at Mayo Clinic and the study's lead author. "Interestingly, we found that nearly 1 in 4 primary care clinicians in our study selected a stool-based test as their preferred screening option, with multitarget stool DNA selected more frequently than either faecal immunochemical test or guaiac-based faecal occult blood test.”
Research has shown that the recommendations of primary care clinicians and gastroenterologists strongly influence whether patients are screened and what type of screening they choose direct visualisation such as colonoscopy, or non-invasive options such as stool-based screening. The findings were reported in the paper, ‘Health Care Provider Characteristics Associated With Colorectal Cancer Screening Preferences and Use’, featured in the Mayo Clinic Proceedings.
To better understand health care providers' preferences and practices with regard to colorectal cancer screening, the researchers developed a survey that was administered online in late 2019 and completed by 779 primary care clinicians and 159 gastroenterologists. According to the survey, colonoscopy was the most frequently preferred option for average-risk patients, favoured by 96.9% of gastroenterologists and 75.7% of primary care clinicians.
While colonoscopy is the most often recommended screening method, a new Mayo Clinic study finds that preferences of primary care clinicians shifted toward noninvasive options in general and particularly for patients who were unwilling to undergo invasive procedures; concerned about taking time from work; unconvinced about the need for screening; or refused other screening recommendations. The research, published in Mayo Clinic Proceedings, suggests that although health care providers prefer colonoscopy for screening, they recognize the need to tailor recommendations to the needs and preferences of patients.
"With the availability of multiple screening options with distinct benefits and drawbacks related to effectiveness, access, cost, risk and patient acceptability, it is critical to encourage informed choice and shared decision-making between patients and their health care providers," added Rutten.
"These findings suggest that primary care clinicians recognize the need to tailor their colorectal cancer screening recommendations to the preferences of their patients, especially with the emergence of new, less invasive options," said Dr Paul Limburg, a gastroenterologist at Mayo Clinic and the study's senior author. "The availability of multiple screening options with differing test attributes and patient acceptability highlights the need for health care providers to share accurate information about all available options to support informed choice and shared decision-making, so that more patients initiate and follow through with their preferred CRC screening strategy.”
The study notes that previous research has demonstrated that the common practice of recommending colonoscopy only may reduce the number of patients who undergo screening, particularly among racial and ethnic minorities, and that offering non-invasive screening options is associated with greater adherence to testing.
