RHEUPP - A Rheumatological Follow-up Management App

The purpose of this Non-inferiority Randomized Clinical Trial is to evaluate the effectiveness of RHEUPP App during telehealth follow-up in a population of Rheumatoid Arthritis patients from a Tertiary Rheumatology Service in South Brazil. The main question\[s\] it aims to answer are: • Using RHEUPP App in telemedicine is not inferior to usual care in terms of means obtained by CDAI. Participants will be stratified by CDAI and then randomized 1:1 for intervention or control group. They will be evaluated at study starting, in 3 and 6 months, an extended evaluation after 12 months of recruitment is predicted. Researchers will compare intervention and control group to detect differences between usual care and Telehealth follow-up and determine if the last is not less effective in our study population of rheumatic patients.
