Description
This logic path provides recommendations on the age to start and to stop screening, modalities and screening intervals for average risk patients, based on U.S. Preventative Services Task Force (USPSTF). It also determines the next due date for screening for average risk patients, based on their age and screening history.
The path is intended for use with either individual patient alerts/flagging or for generating asynchronous reports on a cohort of patients in order to target outreach or escalation.

Recommendation: Start screening at 45 years old Description Start screening at 45 years old. Pseudocode Next due date = date patient is 45 years old. Source: USPSTF, 2021 |
Recommendation: Start screening Description Start screening now. Patients at average risk for colorectal cancer screening should start screening at 45 years old. Average risk recommended screening strategies and intervals: * Colonoscopy every 10 years * High-sensitivity gFOBT or FIT every year * sDNA-FIT every 1 to 3 years * CT colonography every 5 years * Flexible sigmoidoscopy every 5 years * Flexible sigmoidoscopy every 10 years + FIT every year Source: USPSTF, 2021 Pseudocode Next due date = now |
Recommendation: Continue routine screening Description Continue routine screening. Average risk recommended screening strategies and intervals: * Colonoscopy every 10 years * High-sensitivity gFOBT or FIT every year * sDNA-FIT every 1 to 3 years * CT colonography every 5 years * Flexible sigmoidoscopy every 5 years * Flexible sigmoidoscopy every 10 years + FIT every year Source: USPSTF, 2021 Pseudocode See 'Determine Next Due Date' logic path. |
