RHEUPP - A Rheumatological Follow-up Management App

Use of the Multidimensional Health Assessment Questionnaire (MDHAQ/RAPID3) in Follow-up of Patients With Rheumatoid Arthritis by Telemedicine: A Non-Inferiority Randomized Clinical Trial

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.

Participants with access to digital media will be sent a weblink for accessing the study's electronic questionnaires by electronic message or email, with a maximum interval of one week before or after your in-person consultation, according to the research participant's preference. A tablet will be made available to patients who choose to carry out the survey on the day of their in-person assessment. Participants randomized to the intervention group will receive guidance regarding the download or access to the RHEUPP application, with a period of training and adaptation to the tool, to be carried out by Social Monitor.

Inclusion Criteria:

• Adult patients (18y or older)
• Rheumatoid Arthritis according to the 2010 EULAR/ACR criteria
