Objective: To determine the very long-term clinical and functional outcomes in rheumatoid arthritis (RA) patients followed by office-based or hospital-based physicians.
Patients and methods: A questionnaire including items on clinical outcomes (active disease, remission, burn-out) and the Health Assessment Questionnaire (HAQ) was mailed to 122 patients with RA of at least 15 years' duration; 61 were followed by office-based physicians and 61 by hospital-based physicians. In the 88 (72%) respondents, mean age was 63 +/- 13 years and mean disease duration was 20.1 +/- 8.7 years. RESULTS; None of the patients experienced burn-out of their disease, and only six (7%) met Pinals' remission criteria. However, 23 (26%) reported a current subjective remission with a mean duration of 8.5 +/- 5.9 months. Although the mean pain score in the 88 patients was 4.1 +/- 2.3, only 50 (56%) patients reported a physician visit during the last 6 months. HAQ scores varied widely, the mean being 1.11 +/- 0.84. Forty (46%) patients had a history of arthroplasty (knee or hip in 29 (33%)). Of the 34 nonrespondents, seven had died (at a mean age of 74 years), and in four of these seven the cause of death was infection or immobility-related complications; in the 27 survivors, disease activity was considered minimal by the physicians or patients, 11 (41%) patients believed they were in remission, and mean time since the last physician visit was 3.9 years. Conclusion. Although burn-out within 20 years of RA onset seems exceedingly rare, clinical activity is milder than in early RA; over one-fourth of our patients believed they were in remission and over one half had not seen a physician during the last 6 months. Functional outcomes varied widely across patients but were acceptable overall, a result that is partly ascribable to the favorable effects of surgery. No differences in functional outcomes were found between patients followed by office-based physicians and those followed by hospital-based physicians.
