Therapeutic education improves rheumatoid arthritis patients' knowledge about methotrexate: a single center...

To assess, by means of a questionnaire, the effectiveness of a therapeutic education session on rheumatoid arthritis patients' knowledge about methotrexate. Retrospective study of data collected in routine care. STROBE guidelines were used. Rheumatoid arthritis patients treated with methotrexate had a therapeutic education session conducted by a rheumatology nurse at time 0 and 6 months after. They completed a questionnaire to assess their knowledge about methotrexate before the first therapeutic education session and 6 and 12 months after. A score from 0 to 100 was calculated based on 20 questions. A total of 66 patients were enrolled (50 women), with a mean age of 57 years, median disease duration of 4 years, and methotrexate treatment duration of 2 years. The knowledge score improved 6 months after the first therapeutic education session and was unchanged at 12 months. Significant improvement was observed in knowledge about the need for contraception, the contraindication of trimethoprim, the maximum dose not to be exceeded, reduction in alcohol consumption, and the value of combining folic acid with methotrexate. Knowledge about the risk of hypersensitivity pneumonitis did not improve. Skills related to the need for and timing of laboratory testing and contraception were evaluated using two role-playing situations. None of the skills improved. A therapeutic education session improves patients' knowledge about methotrexate at 6 months.
