Patient satisfaction with current psoriasis treatment: a real-world study in the USA

Psoriasis patients often report dissatisfaction with treatment. However, it is less clear how the severity of key psoriasis symptoms (painful skin, itching, and scaling) as well as overall disease severity influence patient dissatisfaction levels. Using the Adelphi 2011/2013 Psoriasis Disease Specific Programmes, two "real world" surveys of US dermatologists and their patients, patient satisfaction was evaluated. Dermatologists provided data on disease characteristics, while patients indicated their satisfaction with existing treatment. Physician-reported severity (none, mild, moderate/severe) of psoriasis-related itching, pain, and scaling, overall disease severity (mild, moderate and severe) and therapy type were compared by patient satisfaction levels (satisfied vs. dissatisfied). Multivariate regressions examined the relationship between patient satisfaction, clinical symptoms, and psoriasis overall disease severity, controlling for differences in patient demographics and comorbidities. The sample comprised 633 psoriasis patients (56% male) with a mean age of 45. Overall, 18% of patients reported dissatisfaction with their psoriasis treatment. Dissatisfied patients were more likely to have moderate (65% vs. 40%) or severe (21% vs 3%) psoriasis compared to patients who were satisfied (both p<0.05). Dissatisfied patients were also more likely to have more severe pain (30% moderate-to-severe pain vs. 9%), more severe itching (61% moderate-to-severe itching vs. 25%), and more severe scaling (68% moderate-to-severe scaling vs. 33%) than satisfied patients (all p< 0.05). Multivariate analyses confirmed these results. Clinicians should be aware that some psoriasis patients, especially those with severe overall disease or symptoms, may be dissatisfied and are in need of better treatment.
