Background/Purpose:

Optimal care in rheumatoid arthritis (RA) includes early use of disease-modifying anti-rheumatic drugs to prevent joint damage and hopefully decrease surgical interventions. Our objective was to determine if persons with RA who saw a rheumatologist early in the disease course had a reduced rate of orthopaedic surgery.

Methods:

All persons with a diagnosis of RA confirmed by a rheumatologist and based on billing code data in the province of Quebec, in 1995 were followed until 2007. Patients were classified as "early consulters" if they were seen by a rheumatologist within 3 months of being diagnosed with RA by their referring physician, "late consulters" if they were seen by more than 3 months after the initial RA diagnosis, and "undetermined" if they were first diagnosed with RA by a rheumatologist. Time to orthopaedic surgery, defined using ICD9 and ICD10 procedure codes, was compared with Cox's proportional hazards regression.

Results:

There were 3,890 patients with a confirmed RA diagnosis: mean age at diagnosis was 56.3 years and 69.4% were female. Most (73%) were "undetermined consulters"; 13.7% were "early" consulters and 13.3%"late" consulters. Among all patients, 15.3% (610) had an orthopaedic surgery during the observation interval. Patients in the early consultation group were less likely to undergo orthopaedic surgery over the 12 year follow-up period than those in the late consultation group (adjusted hazard ratio: 0.63; 95% confidence interval: 0.46, 0.85).

Conclusion:

Persons diagnosed with RA who consult a rheumatologist later in the disease course have a worse outcome in terms of eventual orthopaedic surgery. In addition to improving patient outcomes, appropriate medical treatment under the supervision of a rheumatologist may also decrease costly interventions such as orthopaedic surgery. Our results add more credence to support early treatment guided by a rheumatologist in patients with rheumatoid arthritis.
