Protocols and Practical Considerations

What Is the Optimum Protocol for the Delivery of Psoralen–Ultraviolet A Therapy to Optimize Outcome in Patients With Psoriasis, Eczema and Polymorphic Light Eruption?

Examples of treatment schedules commonly used in the U.K. can be accessed at the following websites:; (the National Managed Clinical Network for Phototherapy in Scotland website); (the South-east of England Phototherapy Network website).

These may be used as guidance to the phototherapist in determining the optimum protocol.

How Should a Psoralen–Ultraviolet A Therapy Clinic Be Set Up?

Taking account of equipment; staffing/training; support (e.g. medical physics, servicing); dosimetry/quality assurance; and records/database, a Phototherapy Working Party Report has been produced by the BAD on the minimum standards for phototherapy services, and includes a phototherapy service review toolkit. It is available at:

In addition, the BPG has also published guidelines for dosimetry and calibration in UV radiation therapy.[375] A joint BAD and BPG update of these guidelines has recently been published in the BJD.[376] Please visit for published BPG workshop reports and for BAD clinical guidelines.
