La. Criswell et al., DIFFERENCES IN THE USE OF 2ND-LINE AGENTS AND PREDNISONE FOR TREATMENT OF RHEUMATOID-ARTHRITIS BY RHEUMATOLOGISTS AND NON-RHEUMATOLOGISTS, Journal of rheumatology, 24(12), 1997, pp. 2283-2290
Objective. To compare the use of methotrexate (MTX), intramuscular (im
) gold, hydroxychloroquine, and prednisone for rheumatoid arthritis (R
A) treatment among patients managed by rheumatologists and nonrheumato
logists. Methods. Multiple regression analysis to estimate the likelih
ood of starting treatment and response to treatment for patients manag
ed by rheumatologists and nonrheumatologists. All regression analyses
were adjusted for patient demographic and clinical characteristics. Re
sults. Therapy with all agents studied was initiated more frequently f
or patients with RA with at least some contact with rheumatologists du
ring the year than for those managed strictly by nonrheumatologists. T
he adjusted odds ratios for starts on these medications ranged from 1.
14 for im gold to 15.11 for MTX for patients managed by rheumatologist
s compared to those managed by nonrheumatologists. However, due to the
low frequency of initiation of treatment with most of these drugs for
patients managed strictly by nonrheumatologists, only the odds ratio
for prednisone reached statistical significance (OR = 2.94, p = 0.0082
). In the year after initiation of therapy with these agents, patients
managed by rheumatologists experienced better response to treatment t
han those managed by nonrheumatologists. These differences were statis
tically significant for MTX (p = 0.0447) and nearly significant for im
gold (p = 0.0597). Conclusion. These results provide evidence of syst
ematic differences in the propensity of rheumatologists and nonrheumat
ologists to initiate therapy with these antirheumatic drugs. If the ob
served differences in initial response to treatment translate into sub
stantial differences in longterm outcomes, then these results suggest
that the welfare of patients with RA may be jeopardized by the current
trend toward primary care and restricted access to rheumatologists.
