ABSTRACT

BACKGROUND: Rosacea is one of the most common skin diseases causing great distress in affected patients. For optimal patient care, epidemiological studies on disease distribution and clinical aspects are essential.

OBJECTIVES: The goal of this study was to provide an updated perspective on the current state of rosacea epidemiology in Germany.

MATERIALS & METHODS: A cohort of 777 rosacea patients was assessed based on a detailed online questionnaire. Information regarding patients' demographics, course and clinical presentation of rosacea, trigger factors, dermatological consultations, treatment adherence and satisfaction as well as quality of life were obtained.

RESULTS: There was a very high self-reported prevalence of primary and secondary rosacea features (flushing: n = 726, 93.4%; papules/pustules: n = 613, 79.0%; telangiectasia: n = 590, 75.9%; sub jective symptoms: n = 691, 88.9%). However, these clinical findings were often underdiagnosed by the treating physicians, while changes in temperature and ultraviolet radiation were potent triggers across all patients (86.3%, 77.7%, respectively). Disease-related quality of life decreased with the number of drugs prescribed as well as with uncontrolled symptom activity, and was reduced in female patients.

CONCLUSION: This study is the largest German-based assessment exclusively focusing on rosacea patients covering a variety of clinical aspects to optimize patient care.
