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.
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.
