Abstract

Objective: To characterise temporal trends and factors associated with the prescription of disease modifying antirheumatic drugs (DMARDs) at the initial consultation in early rheumatoid arthritis (RA).

Methods: Data from 2584 patients with early RA at 19 hospitals were extracted from the Swedish Rheumatoid Arthritis Register for the period 1997–2001. Disease characteristics and DMARD prescription at first consultation with the rheumatologist were investigated using cross tabulation and logistic regression.

Results: DMARD prescriptions, particularly for methotrexate, increased from 1997 to 2001 independently of patient characteristics. Stratification by hospital type showed that patients in district hospitals were less likely to be prescribed DMARDs than those in university hospitals (adjusted odds ratio (OR) = 0.53 (95% confidence interval (CI) 0.40 to 0.69), p<0.001), independently of confounding factors. Association of the DAS28 with the likelihood of DMARD prescription was greater among patients attending district hospitals (OR = 1.65 (1.34 to 2.02), p<0.001) than those at university hospitals (OR = 1.23 (1.07 to 1.41), p = 0.003) and county hospitals (OR = 1.34 (1.01 to 1.63), p = 0.003). Interaction testing indicated that the difference was significant (p = 0.007).

Conclusions: Temporal trends in DMARD prescription indicate an increasingly aggressive approach to disease management among Swedish rheumatologists. However, the association of hospital type with DMARD prescription suggests that the adoption of research findings in clinical care varies considerably.
