Health status in chronic disease: a comparative study of rheumatoid arthritis.

A self-administered questionnaire has been used to measure and compare health status in rheumatoid arthritis (RA) and 5 other chronic diseases. Subjects with RA, hypertension, cancer, diabetes, cardiac disease, or pulmonary disease were assessed along 11 aspects of health status. Results showed significant differences in health status across the 6 diseases, particularly for physical function and pain. The psychological status measures were similar. A summary estimate indicated that RA and pulmonary diseases produced poorer health status than the others. This study confirms the severe negative health status associated with chronic RA.
