Design outcomes

Primary

MeasureTime frame
Duration of remission achieved in psoriasis patients following a course of Narrowband UVB (NbUVB) ismeasured through monthly telephone calls after completion of treatment until study end. Patients are recalled and undergo a skin evaluation if psoriasis has flared.When >50% of the original PASI score is reached, the patients involvement in the study is complete.

Secondary

MeasureTime frame
1. Duration of remission achieved in patients who achieve “complete” clearance of psoriasis versus those who achieve “almost complete” clearance. Complete clearance was defined as 100%, and almost complete as 75-99% clear. 2. Practicality and effectiveness of the 308nm Excimer lamp in clearing more ‘resistant’ plaques alongside a standard course of NbUVB by nurse questionnaire
