Intro ductio n
The task o f o btaining evidence to guide clinical decisio n-
making is particularly challenging in the management o f
go ut, a co nditio n that has been markedly understudied
relative to other rheumatologic disorders. In a comprehen-
sive review o f the MEDLINE database covering the years
1966 thro ugh 2001, there were o nly 23 rando m ized
co ntro lled trials (RCTs) o f go ut treatments; a majo rity o f
these examining the efficacy of nonsteroidal anti-inflamma-
tory drugs (NSAIDs) in the treatment of gout flares [1•]. To
put this into perspective, the number o f go ut RCTs in the
past 30 years is less than the total number of published RCTs
examining rheumatoid arthritis therapies in 2004 alone.
Perhaps as a result o f the po o r quality and quantity of
evidence, there has been little past co nsensus regarding
appropriate standards of gout care. Although an overwhelm-
ing number of physicians report confidence in the diagnosis
and management o f go ut [2], we and o thers have shown
that go ut care is frequently subo ptimal suggesting that the
self-reported confidence of healthcare providers may not be
warranted [3–12]. In this paper, we examine the evidence
suppo rting current strategies in care, fo cusing o n select
management issues that frequently arise in the clinical
setting with the use of currently available gout medications.
In addition, we examine efforts that have culminated in the
publication of gout management quality indicators. We also
discuss the need fo r future initiatives aimed at improving
patient safety and quality of care in gout.
Evidence Supporting
Gout Management Strategies
What is the most effective
treatment for acute gouty flares?
Although there are ample data to support the use of differ-
ent anti-inflammato ry strategies to treat acute go ut flares,
few investigatio ns have been well designed RCTs o r have
co mpared agents acro ss anti-inflammato ry drug classes.
Since RCTs represent the highest level o f clinical evidence
[13], we will fo cus o n RCTs, where available, but otherwise
highlight the best examples o f o ther existing data. The
paucity o f available co mparative data makes it impo ssible
to co nclude superio r efficacy o r to lerability with any
specific treatment for acute gout flares.
Colchicine
Repo rts examining the use of colchicine in gout treatment
are summarized in Table 1. Despite its lengthy and venera-
ble histo ry in the treatment o f go ut, to o ur kno wledge,
there has been o nly o ne rando mized trial examining the
use of oral co lchicine in the treatment of acute gout flares.
Ahern et al . [14•] repo rted the results o f a do uble-blind,
placebo -co ntro lled study invo lving 43 patients with an
acute go ut flare. Patients rando mized to co lchicine were
given 1 mg followed-up every 2 hours by an additio nal 0.5
mg until sym pto m reso lutio n o r the presence o f do se-
related toxicity. The primary endpo ints were 50% improve-
ment in a co mpo site clinical sco re ( based o n a co mbina-
tio n o f pain, tenderness o n palpatio n, swelling, and
redness graded o n a fo ur-po int scale) o r pain sco re alo ne.
At 48 ho urs, 64% o f the co lchicine gro up experienced at
least 50% impro vement in the co mpo site clinical sco re

Gout, a common form of inflammatory arthritis, has been
markedly understudied relative to other rheumatologic
conditions. As a result, evidence guiding clinical manage-
ment in gout has traditionally been lacking. Burgeoning data
suggests that quality of gout care in gout is frequently
suboptimal. In this paper, we examine the evidence
supporting gout management strategies in clinical practice.
In addition, we examine consensus building efforts that
have culminated in the recent publication of gout manage-
ment quality indicators. W e also discuss the need for future
initiatives aimed at improving patient safety and quality of
care in gout.
