Evaluation of treatment satisfaction misalignment between Japanese psoriasis patients and their physicians - Japanese psoriasis patients and their physicians do not share the same treatment satisfaction levels.

High treatment satisfaction in both patients and physicians is an important factor in improving quality of life in psoriasis patients. This study aimed to evaluate treatment satisfaction alignment between psoriasis patients and physicians and to identify factors associated with satisfaction misalignment, especially "physician-predominant" misalignment. This is a nationwide multicenter cross-sectional study. Subjects were paired moderate to severe psoriasis outpatients and their physicians. Treatment satisfaction was evaluated on a scale from 0 to 10. Subjects were defined as "misaligned" when the difference in treatment satisfaction was over ±1 between the patient-physician pair. A total of 425 pairs were collected from 54 facilities in Japan. The mean patient age and disease duration were 56.5 years and 18.7 years, respectively. The mean physician age was 50.6 years and 69.6% of physicians specialized in psoriasis. Treatment satisfaction misalignment was found in 49.9% of the patient-physician pairs. Among misaligned pairs, 43.6% were "physician-predominant" pairs. In the multivariate logistic regression analyses, "treatment is effective" was the most important reason for treatment satisfaction (odds ratio [OR]: 35.5; 95% confidence interval [CI]: 5.43, 231.78). Symptoms in the genital area (OR: 10.2; 95% CI: 2.55, 40.93) and lack of understanding of treatment options by patients (OR: 7.5; 95% CI: 2.19, 25.94) were key factors leading to "physician-predominant" status. The results suggest that genital psoriasis plays an important role in treatment satisfaction from the patient perspective, and illustrate the importance of communication between patients and physicians which potentially resolves these factors and improves misalignment.
