OBJECTIVE: The objectives of this study were twofold: to assess if there are independent effects of variables representing patients' perceptions of disease on intensification of drug therapy in patients with RA seen in daily practice; and to test the hypothesis that effects of patients' perceptions of disease are mediated through patient self-reported willingness to alter therapy. METHODS: Before being seen by a physician, consecutive patients with RA, attending the Radboudumc outpatient rheumatology clinic, were asked to fill out a short questionnaire regarding the following four items: perceived health change, satisfaction with current health, willingness to change therapy and expected health change until the next visit. Independent associations between these measures, registered clinical measures and synthetic DMARD/biologic DMARD (including CSs) intensification were studied with logistic regression. Mediation analysis was performed focusing on the strongest predictor and self-reported willingness as a mediator. RESULTS: Out of 453 patients with RA, 65% female, 67% RF positive, medication was intensified for 82 patients (18%). All patient perception measures exhibited significant associations, independent of clinical measures, of which patient satisfaction with current health state was the strongest [odds ratio (OR) 0.21, 95% CI: 0.10, 0.44]. Significant mediation of the effect of patient satisfaction through willingness to alter therapy on actual registered medication intensification was found. CONCLUSION: Treat to Target interventions should address patients' perceptions of their disease, and the related health goals patients aim to achieve, in addition to the attained level of disease activity.
