Working with the National Rosacea Society (NRS), researchers administered a web-based survey from March 13 to May 26, 2017, to 708 patients who visited the NRS website or received their newsletter.
"These were self-reported rosacea patients, but they had to have had their diagnosis made by a physician. In the past that has been a problem with surveys — there was no way to assure that patients actually had what they thought they had," she says.
The survey also allowed patients to estimate the severity of their erythema using a photographic guide. Most patients (59.2%) had mild rosacea; 33.2% and 7.6% had moderate and severe erythema, respectively.
"When asked what bothers them most about their rosacea, 69% said that it was persistent redness. Another 61% said flushing and blushing," Dr. Baldwin says.
Patients also complained of facial warmness and burning, both of which occurred considerably more often in those with severe rosacea vs. moderate or mild rosacea.
Similarly, both Impact Assessment for Rosacea Facial Redness (IA-RFR) and Dermatology Life Quality Index (DLQI) scores showed statistically significant increases with rising levels of erythema severity (P <0.0001 in both analyses). Regarding IA-RFR components, the greatest mean-score disparities between patients with mild vs. severe erythema occurred in the self-perception (43.2 points), emotional (41.4 points) and social (30.4 points) domains.
