Therapeutic patient education (TPE) is now recognized as a crucial tool in managing conditions like chronic inflammatory rheumatism and in improving treatment adherence. This study aimed to assess whether different TPE programs might improve adherence to subcutaneous anti-tumor necrosis factor (anti-TNF) treatment in patients with rheumatoid arthritis (RA), ankylosing spondyloarthritis (AS), and psoriatic arthritis (PsA).Methods: This was a retrospective, observational, monocentric study of current care practices. We included 193 patients (124 women; mean age 53.3 ± 14.8 years). All patients received subcutaneous anti-TNF treatment and one of three TPE models, delivered by a nurse, from 2009 to 2013. The cohort was grouped according to different educational models: M1: information (N=92); M2: individual TPE (N=80); and M3: individual and group TPE sessions (N=21). Adherence was assessed with the Morisky Medication Adherence Scale (MMAS-4™). Scores were rated as follows: good adherence (MMAS-4 = 4), moderate adherence (MMAS-4 = 2– 3), and poor adherence (MMAS-4 = 0– 1).Results: The mean disease duration was 10 years [95% CI: 5 to 18]. The cohort comprised 113 patients with RA, 73 with AS, and seven with PsA. Overall, 146 (75.7%) patients displayed good adherence, 34 (17.6%) displayed moderate adherence, and 13 (6.7%) displayed poor adherence. The M3 group displayed less adherence than the M1 and M2 groups. Old age was the only factor correlated with good adherence (p=0.005). The level of knowledge had no significant impact on adherence.Conclusion: This study demonstrated good adherence to anti-TNF treatment in patients that received TPE, particularly when it was delivered in individual sessions.Keywords: chronic inflammatory rheumatism, subcutaneous anti-TNF, treatment adherence, therapeutic education
