Abstract

Psoriasis patients often report dissatisfaction with treatment. However, the extent to which patients and their treating dermatologists are aligned regarding satisfaction with psoriasis therapy is largely unknown. This was explored using data derived from the Adelphi 2011/2013 Psoriasis Disease Specific Programmes, two real world surveys of US dermatologists and their patients. Physicians and patients independently reported their satisfaction with psoriasis control (satisfied, dissatisfied). Two levels of satisfaction alignment between physician and patient responses were constructed: aligned (same responses) and misaligned (different responses). In addition, dermatologists provided patient treatment history and disease/symptom severity whereas patients reported data on health-related quality of life (HRQoL), using the EuroQOL 5-Dimension Health Questionnaire (EQ-5D) and Dermatology Life Quality Index (DLQI), and work productivity using the Work Productivity Activity index (WPAI). Multivariate regressions were employed to examine the relationship between satisfaction alignment, overall disease and symptom severity, HRQoL, and work productivity controlling for differences in patient demographics and comorbidities.

From 627 paired dermatologist and psoriasis patient records, 512 (81.7%) and 115 (18.3%) cases fell into the ‘aligned’ and ‘misaligned’ groups, respectively. Compared with patients in the aligned group, those in the misaligned group had more moderate to severe psoriasis (82.3% vs. 43.7%), moderate to severe itching (45.6% vs. 27.8%), pain (23.0% vs. 10.6%), and scaling (54.8% vs. 36.1%), and had lower current biologics use (27.0% vs. 42%) (all p<0.05). The misaligned group was associated with reduced HRQoL (lower EQ-5D score: 0.86 vs. 0.91; higher DLQI score: 7.06 vs. 4.23) and greater work productivity loss (higher WPAI scores: 18.27 vs. 11.43) (all p<0.05). Multivariate analyses confirmed these results (p<0.05). Almost 1 in 5 patients were misaligned with their dermatologist’s level of satisfaction with their psoriasis treatment; misalignment was associated with increased disease and symptom severity, reduced HRQoL, and reduced work productivity.
