Background: Chronic spontaneous urticaria (CSU), characterized by the recurrence of pruritic hives and/or angioedema for >6 weeks with no identifiable trigger, has a negative impact on health-related quality of life (HRQoL). Methods: The objective of this web-based cross-sectional study was to evaluate disease control, disease burden, and treatment satisfaction in Japanese adults with CSU using the Urticaria Control Test (UCT), HRQoL outcomes, and the Treatment Satisfaction Questionnaire for Medication-9 items (TSQM-9). Results: In total, 529 adults were included in the analysis (59.9% female), with a mean ± standard deviation (SD) in CSU duration of 13.2 ± 13.0 years. Based on UCT scores, two-thirds of patients had poor (score of 0-7; 23.6%) or insufficient (score of 8-11; 43.3%) symptom control, and one-third had good control (score of 12-16; 33.1%). Overall treatment satisfaction was not high, with mean ± SD TSQM-9 scores of 55.5 ± 17.6% for effectiveness, 68.2 ± 18.8% for convenience, and 59.2 ± 18.4% for global satisfaction. No apparent differences in TSQM-9 scores were observed between patients receiving different medications. HRQoL outcomes were worse among patients with poor/insufficient symptom control. Conclusions: Japanese adults with CSU have a high disease burden, and better treatment options are needed to increase treatment satisfaction.
