Time Spent per delta PASI (TSdP) among psoriasis patients undergoing UVB-therapy – A pilot study

AbstractBackground: Psoriasis often poses a significant challenge to treat. Ultraviolet light band (UVB) treatment is widely used and well recognized. However, the frequent visits to the dermatologist may indirectly present an impediment to many of the patients’ careers and every day life due to the vast time burden with subsequent lost work earnings.

The time spent in relation to each treatment session was reported in a questionnaire given to the patient. Time Spent per delta PASI (TSdP) was defined as number of minutes to reduce the PASI score by one. Results: Seventeen (68%) of the participants needed less than 300 min to lower the PASI wi...
