Using the patient-acceptable symptom state to evaluate patients' perspectives of living with psoriasis: A cross-sectional study

Abstract

Background: Taking the perspectives of patients into consideration is of the utmost importance when defining treatment goals for psoriasis. The patient-acceptable symptom state (PASS) is a dichotomised question that captures patients' perceptions of their overall health state. Objectives: To evaluate PASS and determine the factors associated with a satisfactory PASS for psoriatic patients. Methods: Three questions were asked: (Q1) Considering the ways that your skin symptoms affect your functioning, is your current skin psoriasis satisfactory? (Current PASS), (Q2) Considering the ways that your psoriasis is affecting you, if you were to remain in this state for the next few months, would this be satisfactory? (Future PASS) and (Q3) If you were to remain for the rest of your life as you were during the last 48 hours, would this be satisfactory? (Lifelong PASS). Disease severity, symptoms and health-related quality of life (HRQoL) were collected. Results: Of 140 patients, 74.3%, 70.0% and 85.7% expressed satisfaction with their current, future and lifelong skin psoriasis conditions respectively. A satisfactory PASS was significantly associated with older and married patients; lower disease severity; fewer skin symptoms; and a higher HRQoL. A multivariate analysis revealed that the independent factors associated with a satisfactory PASS were being older than 40 years, being married, practising meditation, not having extensive lesions at sensitive areas and having a high HRQoL. Conclusions: PASS is a simple and easily administered questionnaire that reflects both disease severity and HRQoL. Understanding patients' needs and satisfaction levels will result in better care for psoriatic patients than otherwise.
