Chronic itch can be a debilitating medical condition with clinical characteristics and impact akin to chronic pain. Itch severity is subjective and clinicians depend on patient reported numerical ratings scales (NRS); most commonly 24-hour worst itch (WI-NRS) has been validated including large scale studies. WI-NRS does not attempt to take into account itch duration or the variability that is often experienced throughout the day and night by chronic itch patients.
