Are narrow-band ultraviolet B home units a viable option for continuous or maintenance therapy of photoresponsive diseases?
BACKGROUND
Phototherapy is an effective treatment for several photoresponsive diseases. Many patients are unable to attend hospital-based treatment and prefer home phototherapy.


OBJECTIVE
The purpose of this study is to survey patients who were prescribed home phototherapy to determine the viability of narrow-band ultraviolet B home units in the continuous or maintenance treatment of photoresponsive diseases.


METHODS
A patient questionnaire was prepared focusing on different areas of interest: the reason for choosing home therapy, appropriate teaching, previous medical treatment, present exposure therapy, improvement of the condition, side effects, regular dermatologic follow-ups, and the effectiveness of this approach. Twenty-seven patients who attended the photodermatology clinics at the Sisters of Charity of Ottawa Health Service at the Elisabeth Bruyère Health Centre in Ottawa and the Ottawa Hospital Civic Campus were contacted, and they completed a questionnaire by telephone or electronic mail.


RESULTS
Twenty-five patients completed the questionnaire. One refused to participate, and one was out of the country. The main reasons for choosing home phototherapy were time (40%), travel expenses (25%), difficulty with work schedule (17%), and recommendation by a physician (6%). Other reasons included loss of earnings, personal stress, knowledge that the disease recurs when phototherapy is discontinued, moving from the city, personal stress, and the convenience of being at home. Regarding the effectiveness of the home phototherapy, 24 patients (96%) viewed the home unit approach to be effective. All patients agreed that they would continue the treatment; they would repeat it, and they would recommend it. Few patients reported side effects, such as erythema (36%), blisters (1%), pruritus (8%), and dryness (1%). Fourteen patients (56%) reported not experiencing any side effects.


CONCLUSIONS
Narrow-band ultraviolet B home phototherapy was found to be an effective form of maintenance therapy for photoresponsive diseases. It is safe and presents few side effects when patients receive appropriate guidelines, teaching, and follow-ups.
