Effect of the Automatic Surveillance System on Surveillance Rate of Colorectal Postpolypectomy Patients
Study Details
Study Description
Brief Summary
In this study, we proposed a prospective study about the effect of the automatic surveillance system on surveillance rate of colorectal postpolypectomy patients. The enrolled patients were divided into group A with intelligent surveillance system reminding though telephone and message, group B with intelligent surveillance system reminding though message, group C with manual reminder, and group D with natural state. The surveillance among the four groups were compared.

Detailed Description
The adherence of doctors to published colorectal post-polypectomy surveillance guidelines varies greatly, and patient follow-up is critical but time-consuming. Previous studies we developed an automatic surveillance (AS) system to accurately identify post-polypectomy patients, assign surveillance intervals for different risks of patients and proactively follow up with patients in time. In this study, we proposed a prospective study about the effect of the automatic surveillance system on surveillance rate of colorectal postpolypectomy patients. The enrolled patients were divided into group A with intelligent surveillance system reminding though telephone and message, group B with intelligent surveillance system reminding though message, group C with manual reminder, and group D with natural state. The surveillance among the four groups were compared.

|---|---|
| Experimental: With automatic surveillance system reminding through telephone and message Patients were reminded of the surveillance time by an automatic surveillance system after the endoscopic and pathological results were available and before the surveillance time through telephone and message. |
Other: AI based automatic surveillance (AS) system (ENDOANGEL-AS) reminds the patients through by telephone .
