[Quality of life of patients with rheumatoid arthritis undergoing out-patient treatment with TNF inhibitors]

Abstract

Objective: To assess the quality of life of patients with rheumatoid arthritis undergoing out-patient treatment with TNF inhibitors (etanercept and adalimumab).

Method: Observational, descriptive and multi-centre study. A specific validated questionnaire was used (QOL-RA Scale) in its Spanish version, with complete confidentiality ensured. To measure the reliability of the results, the Cronbach Alpha Coefficient was used. A descriptive analysis was carried out to compare the results obtained with those obtained from studies in the USA and Colombia.

Results: A total of 82 patients were selected who mainly consisted of married housewives who had not undergone any previous studies. The average amount of years from diagnosis was 11.81 years (SD: 7.30) and the average duration of treatment with TNF inhibitors was 1.71 years (SD: 1.03). The results of the questionnaire were: physical ability 5.42 (SD: 1.67), pain 5.10 (SD: 1.83), social life 7.08 (SD: 1.96), support 7.45 (SD: 2.10), mood 6.02 (SD: 2.03), stress 5.50 (SD: 2.01), arthritis 5.15 (SD: 1.86), health 5.50 (SD: 1.77). The results obtained were similar to those from the USA, although they showed a lower score for mood and stress categories. However, the high score in the support and social-life categories was more similar to that obtained with the Colombian questionnaire. All patients considered their quality of life to have improved with the use of TNF inhibitors.

Conclusions: The quality of life in patients with Rheumatoid Arthritis is low, determined by pain and symptoms of depression. The patients believe that TNF inhibitors have improved their quality of life.
