Remodeling a rheumatology practice to facilitate early referral

Time to Treatment for New Patients with Rheumatoid Arthritis in a Major Metropolitan City

Objective.

To determine the proportion of patients with rheumatoid arthritis (RA) seen by rheumatologists and treated with disease-modifying antirheumatic drugs (DMARD) within 3 months of symptom onset, to determine where treatment delays occur, and to identify contributing factors.

Methods.

A retrospective cohort study in which adult patients with RA, diagnosed between January 1, 2003, and May 31, 2006, were recruited from rheumatologists’ offices to participate in a telephone survey and chart review. The percentage treated with DMARD within 3 months of symptom onset was determined, along with median times for delay. Factors contributing to the delay were explored using multivariable logistic regression.

Results.

Our study included 204 patients. Within 3 months of symptoms, 22.6% (95% CI 16.8%, 28.3%) received DMARD and within 6 months, 47.6% (95% CI 40.7%, 54.4%). The median time from symptom onset to DMARD was 6.4 months [interquartile range (IQR) 3.3, 12.0] with a median time from RA diagnosis by a rheumatologist to DMARD of 0.0 months (IQR 0.0, 1.0). Higher baseline swollen joint counts resulted in earlier treatment. Age, sex, education, comorbidity, rheumatologist practice type, and years since the physician’s graduation did not affect time to treatment.

Conclusion.

Fewer than 25% of patients referred to rheumatologists were treated within 3 months of symptom onset. Identification of inflammatory arthritis and referral to rheumatologists are the key factors in timely care, because once patients are seen there is no delay to treatment. Future resources should be focused on development and evaluation of interventions to facilitate rapid triage, referral, and assessment by a rheumatologist.

Identification of undiagnosed inflammatory arthritis in a community health fair screen

OBJECTIVE

To identify individuals with undiagnosed inflammatory arthritis (IA) and rheumatoid arthritis (RA) in a community health fair screen, and to establish in a health fair setting the diagnostic accuracy of combinations of the Connective Tissue Disease Screening Questionnaire (CSQ) and autoantibody testing for IA.

METHODS

Screening for IA/RA was performed at health fair sites using a combination of the CSQ, joint examination, rheumatoid factor, and anti-cyclic citrullinated peptide (anti-CCP) antibody testing. IA was defined as > or =1 swollen joint suggestive of synovitis on joint examination by a trained clinician.

RESULTS

Six hundred one subjects were screened; 51.0% participated because of joint symptoms (pain, stiffness, or swelling). Eighty-four subjects (14.0%) had > or =1 swollen joint, designated as IA on joint examination. Of the 601 subjects screened, 9 (1.5%) had IA and met > or =4 of 7 American College of Rheumatology criteria for RA but had no prior diagnosis of RA, and 15 (2.5%) had IA and RF and/or anti-CCP positivity, suggesting early RA. The diagnostic accuracy of combinations of the CSQ and autoantibody testing for the identification of IA yielded maximal sensitivity, specificity, and positive and negative predictive values of 95.3%, 99.2%, 71.4%, and 97.7%, respectively.

CONCLUSION

Health fair screening may be an effective approach for the identification of individuals with undiagnosed IA/RA. A combination of the CSQ and autoantibody testing alone has clinically useful diagnostic accuracy for the detection of IA. Decisions regarding which methodology to use for future health fair IA/RA screening will depend on goals of screening and funding.
