RESUMO
OBJECTIVE: The purpose of rheumatoid arthritis (RA) patient education is to increase patients' knowledge levels. However, there are only a limited number of studies available concerning these patients' knowledge of their disease and its various treatments. The purpose of this study was to describe RA patients' understanding of their disease and its treatments. METHODS: A total of 252 RA patients participated in this survey in August 2004 (response rate 53.2%). The knowledge levels of the patients and their physical functioning were measured using self-reported questionnaires. The data were analysed using descriptive and non-parametric statistical methods. RESULTS: RA patients' knowledge of the disease and its treatments was, on average, good. However, the total scores of the Patient Knowledge Questionnaire ranged from 2 to 29 (maximum score 30). The patients knew well the aetiology and symptoms of RA, the blood tests and the physical exercise; they knew moderately well the facts relating to joint protection, energy conservation and how to use anti-rheumatic drugs and non-steroidal anti-inflammatory drugs. Young patients, women and patients with a long disease duration knew the most. There was a weak correlation between patient knowledge and physical functioning: the weaker the patient's functioning, the higher the knowledge level. CONCLUSIONS: RA patients' knowledge of their disease and its treatments varied from poor to good in this group. These results can be used for advancing RA patient education. However, more research is needed to evaluate RA patients' knowledge levels.
