Dear Kevin, Greetings from Al-Ain the oasis city of the Middle East. Regarding your above posting the following might be relevent. I could not find any systematic review or an RCT on your question. I found this paper in Medline. Lowe NJ. Home ultraviolet phototherapy. Semin Dermatol 1992 Dec;11(4):284-6 Home UV phototherapy is extremely popular with many psoriasis patients. However, it is essential that they understand the need for regular skin examination by the dermatologist. Patients with psoriasis are not trained nor are many nondermatologist physicians to recognize the early features of many skin cancers, and continued home UV therapy in the presence of such skin cancers is clearly unwise for the safety of that patient. The use of UVA tanning salon treatments in the therapy of psoriasis is usually unsuccessful and is extremely unwise with concomitant psoralen and drug therapy. This is to be discouraged, and the patient should always be treated with PUVA in the dermatologist's office with carefully monitored UVA machines and staff trained in the administration of PUVA phototherapy. It appears that trained personnel should administer phototherapy under the supervision of dermatologists at least for psoriasis. When I did a quick search on the web I found that the Royal Adelaide hospital (http://www.rah.sa.gov.au/internal/dermatol.htm) adopts a team approach in the care of skin patients. Their Dermatology Day Care Treatment Center offers an alternative to inpatient care for patients with severe skin conditions such as psoriasis and dermatitis. The centre services include among other things phototherapy. The Day Care Center is staffed by medical Specialists, specialist nurses as well as experienced physiotherapists and dietitians. Probably the physiotherapists provide phototherapy under the guidance of dermatologists. Hope members of the list will throw more evidence based light on your question and my posting is of some help.
