This page describes patient-reported outcome measures in urticaria.
Monthly
The UCT covers the following 4 domains:
- Validated and specifically designed for chronic urticaria
- Self-administered, retrospective (past 4 weeks) 4-item questionnaire
- Each answer is scored ranging from 0 to 4
- The summed score ranges from 0: no control to 16: full control
Daily
A method for assessing disease severity
- Tools are available for angioedema-only patients2
- Patient scores their number of hives (0 to 3)† and pruritus severity (0 to 3) each day for 7 days2
- Maximum weekly score is 42 – a higher score corresponds to more severe disease2
- Severe CSU has a UAS7 score of 28–423
*Included in the NICE guidance as an example of objective assessment of disease severity.
†Scoring from 0 (none) to 3 (intense).
Weekly
The DLQI is a simple, validated questionnaire used to evaluate health-related quality of life in patients with skin diseases.
- It consists of 10 questions comprising 6 domains:
Symptoms and feelings
Daily activities
Personal relationships
Leisure
Work and school
Treatment
- The effect of the disease on each domain is scored from 0 (not at all) to 3 (very much) for each question, giving a total score of between 0 and 30
- Higher DLQI score corresponds to greater impairment on quality of life
PATIENT-REPORTED OUTCOMES RESOURCE
The patient-reported outcomes guideline presents patient-reported outcomes for healthcare professionals to use with patients with CSU; these outcomes include the UCT, UAS7 and DLQI.
As part of our mission to be as environmentally friendly as possible, we provide our resources in electronic form.
These materials should not be printed by healthcare professionals.
CSU, chronic spontaneous urticaria; DLQI, Dermatology Life Quality Index; UAS7, urticaria activity score at seven days; UCT, urticaria control test.
