Patient Prioritisation of Impact Items to Develop the Patient-Reported Impact of Dermatological Diseases (PRIDD) Measure: European Delphi Data

The study involved 1154 adults with dermatological diseases, aiming to develop a new measure, PRIDD, to assess the impact of these diseases on patients' lives. The study identified 263 areas of impact and prioritized them through a global Delphi study. The top three impacts were skin sensitivity, dissatisfaction with the quality of nails, skin, hair, and physical discomfort. Psychological impact was the most significant, especially in 30- to 39-year-olds and more pronounced in females (55%) than in males (45%). Physical impact was the second most significant, particularly in 60- to 90-year-olds, and more prevalent in males (35%) than in females (25%). The study concluded that a biopsychosocial approach is needed for patient management, as focusing solely on physical symptoms is unlikely to reduce the burden of dermatological diseases. The findings will inform the development of the PRIDD measure, which is currently in the psychometric testing phase.
