ABSTRACT
OBJECTIVE: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a complex, chronic autoimmune disease, and its diagnosis triggers considerable anxiety and uncertainty for those affected. There are currently no valid data describing the impact of disease-specific patient education on the disease knowledge, subjective impairment, and changes in lifestyle habits related to AAV. METHOD: We designed a one-day educational programme to serve AAV patients with information about their disease and its treatment. Patients were randomized into an intervention group and a waiting list control group. Increase in knowledge was measured with a multiple-choice test. The intervention group completed the questionnaire before, directly after, and 3 months after the seminar, while the waiting list control group was additionally tested 3 months before the seminar to rule out non-specific learning. Furthermore, we investigated the burden of the disease and the impact of our intervention on this burden. RESULTS: Compared with the control group, the intervention increased the knowledge (mean ± sd score difference 2.2 ± 1.0, 95% confidence interval 0.1-4.3, p = 0.04). From the patients' point of view, their understanding of the disease had improved and the subjective impairment caused by their rheumatic disease had decreased. There was a tendency to include disease-relevant behaviour, such as nasal care or dietary recommendations, more often in everyday life. CONCLUSION: A one-day seminar is suitable to increase the disease-specific knowledge of patients with AAV in a sustainable manner. In addition, our measure positively affected the disease-relevant behaviour.
