Abstract: Objective: To explore the effects of the cloud-based feedback health education on patients with Inflammatory Bowel Disease at home. Methods: Patients with Inflammatory Bowel Disease discharged from the Department of Gastroenterology of a tertiary grade A hospital in Qingdao were recruited by convenience sampling method. Fifty-six patients admitted from October to December 2022 were treated as the control group and routine out-of-hospital follow-up was provided. Another 56 patients admitted from January to March 2023 were assigned to the observational group and feedback education based on cloud platform was provided. The self-management ability, knowledge level, medication compliance, BMI, serum albumin, prealbumin and observation group were compared 3 months after discharge. Results: Two patients in the control group and two patients in the observational group withdrew from the study. There were no statistically significant differences in the dimensions of self-management ability, knowledge level, medication compliance, Body Mass Index, serum albumin and prealbumin between the two groups before intervention (P>0.05). After 3 months of discharge, scores of all dimensions of self-management ability, knowledge level, medication compliance and BMI of patients in the observational group were higher than those of the control group. The knowledge level and medication compliance of patients in both groups were better than those before intervention (P<0.001). Three months after discharge, there were no significant differences in serum albumin and prealbumin between the two groups. The total number of reading in the cloud platform was 3500 , and the mean length of reading duration was 5.84±2.11 min. Conclusion: The feedback health education based on cloud platform can improve patients' self-management ability, knowledge level, medication compliance, and body mass index. However, such an education cannot change the serum albumin and prealbumin level.
