RESUMEN
Objectives@#This study aimed to investigate the prevalence, incidence, and real-world diagnostic and treatment patterns, healthcare resource utilization (HCRU), and associated costs of narcolepsy in Germany. @*Methods@#This study was based on German claims data (2013–2018). Any patient with at least two outpatient specialist diagnoses and/or one inpatient diagnosis of narcolepsy was eligible for inclusion. Three cohorts were specified: 1) narcolepsy-prevalent patients alive on July 1, 2017; 2) narcolepsy-incident patients; and 3) newly treated patients. Descriptive analyses of the outcome measures were conducted. @*Results@#We identified 133 prevalent narcolepsy patients (mean age: 46.2 years, 36.3% female), 71 incident patients, and 41 treatment starters. The prevalence of narcolepsy was 3.1–9.1 per 100,000 persons within the German population; the cumulative incidence between July 1, 2017, and June 30, 2018, was 0.83/100,000 persons. Among the incident patients, 62.0% underwent at least one predefined diagnostic procedure. Modafinil was the most prescribed medication for the treatment starters (46.3%) and prevalent patients (24.1%), but 59.4% of the prevalent patients did not receive any narcolepsy-specific pharmacological treatment. Prevalent patients with narcolepsy consulted physicians significantly more often than a healthy matched control group and experienced more all-cause hospitalizations. The mean total direct healthcare costs were higher for narcolepsy patients by €2,429 per patient-year. @*Conclusions@#Not all narcolepsy patients undergo appropriate diagnostic procedures or narcolepsy-specific medications, as indicated by the treatment guidelines. More emphasis on the optimization of the management of this disease is needed, given its high prevalence and associated economic burden.
