Efficacy
Statistical methods / analysis
The aim of the test will be to test if on average a 50% reduction in PASI score is achieved across all patients enrolled in the trial between baseline and final measurement. Carlin et al (J Am Acad Dermatol. 2004 Jun;50(6):859-66) found that a 50% reduction in PASI score represents a clinically meaningful reduction in disease and should be the benchmark for future treatment tests.

Summary
Brief summary
Will bathing in a geothermal water reduce skin rashes due to psoriasis? People will be recruited who still have psoriatic skin rash despite other treatments. Participants will be randomly selected to receive either the intervention schedule or the control schedule first. The intervention and the control schedules are to bathe at QE Health at intervals over 20 days and we assess the rash at each visit using PASI scoring for size, redness and scaling and ask how the rash has been. Assessments include PASI scoring. Plus a questionnaire, photographs of the rash and vital signs are recorded at the first and last visits of each schedule.
Participants crossover and do both schedules one after the other
