Background:
ItchyQuant is a validated patient-reported outcome measure rating itch. Assessment of subjective itch is important in clinical care to adequately understand disease burden.
Objective:
To assess itch severity among patients seen at a high-volume academic dermatology center and characterize variations in itch severity by demographic group and primary diagnosis.
Methods:
ItchyQuant was sent to every patient via e-portal 7 days prior to any non-Mohs dermatology encounter. Multinomial logistic regression compared data collected over 2 years.
Results:
Cohort included 8907 patients (mean age 52 years, 67.4% female, 75.0% White) who responded >0 to ItchyQuant. Increase in age, female sex, and Black race were significantly associated with a higher likelihood of both moderate and severe compared to mild itch. Hispanic compared to non-Hispanic patients were more likely to experience moderate itch. Patients with nonvisible sensations compared to inflammatory/rash diagnoses were more likely to report severe itch.
Limitations:
Single-institution retrospective study; patient-reported outcome measures deployed only in English.
Conclusion:
Black, Asian, and Hispanic patients reported higher itch severities than White and non-Hispanic counterparts while overall itch severities were consistent across age groups >45 years. Our data highlight the feasibility of broad ItchyQuant deployment without clinical workflow disruptions and suggest that itch disparities exist.
