Colonoscopy Needs Calculator – NCCRT

Colonoscopy Needs Calculator
This calculator is designed to estimate the number of colonoscopies your practice or healthcare system may require with a high quality stool-based colorectal cancer screening program, based on a specific patient population. Calculator Savings Chart
The calculator will also provide you with an estimated cost of providing colonoscopies for patients that require screening by colonoscopy either based on their personal risk or for patients that receive an abnormal result on a stool-based test. This cost can then be compared to an approximate cost to treat the estimated number of cancer cases if screening is not prioritized.

The American Cancer Society and the US Preventive Services Task Force now recommend that colorectal cancer screening begin at age 45. The ACS firmly believes that the evidence, including a concerning trend in colorectal cancer incidence in younger adults, now points to colorectal screening initiation starting at age 45. Having said that, implementation will be a multi-year process, as measurement and coverage issues are worked out. We recognize that many organizations will continue to follow the USPSTF recommendations for the time being. Learn more about the implementation timeline for the 2021 USPSTF colorectal cancer screening recommendation in NCCRT’s June 7, 2021 webinar.
View “determining risk threshold” citations on the reference page for more information. This will be the basis for your "average risk" population that is eligible for a non-colonoscopy test to screen for CRC. It is estimated that 85% of 50-75 year olds are average risk for CRC.
View “determining risk threshold” citations on the reference page for more information. This will be the basis for your "high risk" population that will require a direct referral to colonoscopy. It is estimated that 15% of 40-75 year old patients will require direct colonoscopy. This total will be added to the number of average risk patients needing follow up to positive stool test results to determine the total number of colonoscopies needed for your population.
You may choose to report your most recently calculated UDS or HEDIS rate, which currently capture screening between the ages of 50-75, if available. If you need guidance on how to calculate your rate, the NCCRT resource, Steps For Increasing Colorectal Cancer Screening Rates: A Manual For Community Health Centers, includes guidance on how to determine baseline screening rates beginning on page 9.
You may choose to enter your practice or system’s target rate or a target rate determined by a state or national organization, such as the 80% target of the NCCRT’s 80% in Every Community initiative.
View “expected FIT positivity and percent for cancer” citations on the reference page for more information. It is estimated that FITs will have a 5% - 10% positivity rate requiring follow up with colonoscopy. If you are using FIT and don't have an actual rate, 7.5% is suggested as the average. You may also refer to your FIT, gFOBT or FIT-DNA manufacturer for additional guidance.
