BACKGROUND Telemedicine plays an important role in the management of patients with inflammatory bowel disease (IBD), which is especially evident during the pandemic such as COVID-19. However, the exact effectiveness and efficiency of telemedicine in managing IBD is unclear. OBJECTIVE We aimed to compare the impact of telemedicine on management of IBD patients with the standard care. METHODS We systematically searched the PubMed, Cochrane Library, EMBASE, Web of Science, and Scopus (search date April 22, 2020). Randomized controlled trials (RCTs) comparing telemedicine with standard care in IBD patients were included, while conference abstracts, letters, reviews, laboratory studies, or case reports were excluded. The IBD-specific quality of life (QoL), disease activity and remission rate of IBD patients were assessed as primary outcomes, and the number of clinic visits per patient, patient satisfaction, psychological outcome, and medication adherence were regarded as secondary outcomes. The Review Manage 5.3 and Stata 15.1 were used for the data analysis. RESULTS 17 RCTs (n=2571 participants) were included in this meta-analysis. The telemedicine group had higher IBD-specific QoL than the standard care group [standard mean difference (SMD) 0.18, 95% confidence interval (CI) 0.01 to 0.34，P=0.03)]. Furthermore, the number of clinic visits per patient in the telemedicine group was significantly lower than that in the standard care group (SMD -0.71, 95%CI -1.07 to -0.36, P CONCLUSIONS Telemedicine intervention showed a promising role in improving IBD-specific QoL among adolescents and decreased the number of clinic visits of IBD patients. Further researches are warranted to identify the ideal group of IBD patients who could benefit from telemedicine most.

Randomized controlled trials comparing telemedicine with standard care in patients with IBD were included, while conference abstracts, letters, reviews, laboratory studies, and case reports were excluded. The IBD-specific quality of life (QoL), disease activity, and remission rate in patients with IBD were assessed as primary outcomes, and the number of in-person clinic visits per patient, patient satisfaction, psychological outcome, and medication adherence were assessed as secondary outcomes. Review Manage 5.3 and Stata 15.1 were used for data analysis. Results A total of 17 randomized controlled trials (2571 participants) were included in this meta-analysis. The telemedicine group had higher IBD-specific QoL than the standard care group (standard mean difference 0.18, 95% CI 0.01 to 0.34; P.03).
