assessment of rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, plaque psoriasis, crohn's disease and ulcerative colitis patients´ adherence attitudes to maintenance therapy with a scheduled adalimumab treatment in routine clinical practice

Conditions: Rheumatoid Arthritis; Ankylosing Spondylitis; Psoriatic Arthritis; Crohn´s Disease; Ulcerative Colitis; Plaque Psoriasis

Summary: the purpose of this non-interventional, multicenter, post-marketing observational study (pmos) was to assess rheumatoid arthritis (ra), psoriatic arthritis (psa), ankylosing spondylitis (as), plaque psoriasis (ps), crohn's disease (cd) and ulcerative colitis (uc) patients' adherence attitudes (beliefs) to maintenance therapy with adalimumab monotherapy or combination therapy with methotrexate (in participants with ra) and to investigate whether there were correlations between such beliefs and adherence to maintenance treatment.

adalimumab was prescribed in the usual manner in accordance with the terms of the local marketing authorization with regards to dose, population and indication. the assignment of a participant to an adalimumab-containing regimen was decided in advance and was to be current practice. the prescribing of adalimumab was clearly separated from the decision to include the participant in the study. participants were observed for a maximum of 12 months, with a total of 5 study visits (screening = visit 1).
