Events
| Name | Description |
|---|---|
Most recent CRC screening test is colonoscopy? | |
Endoscopist recommended interval in most recent colonoscopy? | The interval recommended by the endoscopist for the next screening or surveillance colonoscopy. |
'Recommended follow-up interval' associated with latest 'Colonoscopy' exists | |
Actions
Recommendation: Patient should be under colonoscopy surveillance Description Recommendation: Patient is at increased risk due to a history of potentially precancerous polyp(s). Colonoscopy surveillance is recommended. Pseudocode |
Recommendation: Next due date per endoscopist-recommended interval Description Recommendation: Follow endoscopist-recommended interval. Considerations: * Interval may be shorter than 10 years even if most recent colonoscopy is normal (e.g. when a patient had advanced adenoma(s) in baseline colonoscopy). Pseudocode Next due date = DATE of latest 'Colonoscopy' date + 'Recommended follow-up interval' associated with latest 'Colonoscopy' |
Recommendation: Follow-up with endoscopist Description Recommendation: Follow-up with endoscopist to determine appropriate interval for next colonoscopy. Considerations: * Interval may be shorter than 10 years even if most recent colonoscopy is normal (e.g. when a patient had advanced adenoma(s) in baseline colonoscopy). Pseudocode |
