Measuring the severity of rosacea: a review
Charles E. Gessert, MD, MPH, and Joel T. M. Bamford, MD
Abstract

Background Assessment of severity is essential in the clinical care
of rosacea patients and in the research on rosacea.

Objective To determine the range of methods used to assess rosacea
severity in clinical trials.

Methods The medical literature from 1965 through 2001 was searched
for rosacea clinical trials using MEDLINE and published citations.
Forty-seven articles were reviewed.

Results The most frequently assessed signs of rosacea were
papules/pustules (43 studies), erythema (35), and telangiectasia
(24). Other signs and symptoms of rosacea and adverse reactions to
therapies were assessed in 27 studies. Counts of papules/pustules
were conducted in 34 studies. Four-point scales were the most
frequently used assessment tools for erythema (17) and telangiectasia
(11). Other frequently used techniques included global assessment by
clinicians (29) and by patients (21), and photography (13).

Conclusions At present, there are no standard validated tools for
assessing the severity of rosacea or its signs or symptoms.
