BACKGROUND: Although the effectiveness of biologics for psoriasis has been measured extensively with objective outcome measures, studies based on subjective, patient-reported outcome measures remain scarce. OBJECTIVES: To investigate satisfaction with medication, as measured by the Treatment Satisfaction Questionnaire for Medication (TSQM) for biologics in daily practice psoriasis care in the first 6 months of treatment; and to identify possible differences in satisfaction with medication between patients experienced (biologics-experienced) and inexperienced (biologics-inexperienced) in the use of biologics. METHODS: TSQM baseline measurements were compared using measurements taken after 6 months, using the Wilcoxon signed-rank test for paired comparisons. Intention-to-treat with last observation carried forward (ITT with LOCF) and as-treated analyses were performed. The difference between biologics-experienced and biologics-inexperienced patients for TSQM was analysed using ITT with LOCF. At 6 months, outcomes for biologics-experienced and biologics-inexperienced patients were compared using the Mann-Whitney U-test. RESULTS: One hundred and six patients were eligible for analysis, and treated with etanercept (n = 34), adalimumab (n = 49) or ustekinumab (n = 23). Fifty-four per cent of patients were biologics-inexperienced. A statistically significant improvement was seen in all domains of the TSQM ('effectiveness', 'side-effects', 'convenience' and 'global satisfaction') by comparison of months 3 or 6 with baseline (all P ≤ 0·02). After 6 months, biologics-inexperienced patients scored better on the 'global satisfaction' domain than biologics-experienced patients (P < 0·01). CONCLUSIONS: We provide a prospective, longitudinal analysis of TSQM for biologics in daily practice psoriasis care. High satisfaction rates were achieved. The 'effectiveness' and 'convenience' domains showed the most room for improvement.
