Study typeObservational study
Brief description of the studySystemic SLE erythematosus SLE is a multisystem autoimmune disorder of connective tissue characterized by autoantibodies that target nuclear antigens, remissions and flares, and a highly variable clinical presentation, disease course, and prognosis. The disease course is more severe in childhood-onset compared to adult-onset SLE, with higher prevalence of morbidity and lower survival rates. In contrast to adult SLE, there is limited good quality evidence on the treatment of childhood SLE. Therefore, to review new drug applications, it would be important for the European Medicines Agency EMA to understand the current clinical practice of treating SLE in paediatric population and differences with the treatment in adult population. The overall objective of this study is to characterise paediatric and adult patients with SLE diagnosed in the period 2013-2022. This will be a patient-level characterisation and drug utilisation study.

14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
For objectives 1 to 4, follow up will start from date of first SLE diagnosis until the earliest of the following loss to follow up, end of data availability, or date of death.
For objectives 5 and 6, follow up will start from date of first SLE treatment after SLE diagnosis until the earliest of the following loss to follow up, end of data availability, or date of death.
15. Data analysis plan
Please provide a brief summary of the analysis method
Large scale patient level characterisation will be conducted. Medical condition and medication use history will be reported at any time and 365 days prior to index date, respectively. The number and percentage of patients receiving each of a pre specified list of SLE treatments and treatment combinations will be described per calendar year. Additionally, sunburst plots and Sankey diagrams will be used to describe treatment patterns and sequences over time. For the new user cohort, the index date is the initiation of SLE treatment after SLE diagnosis. Treatment duration, initial dose strength, cumulative dose, number of prescriptions will be estimated for new users of each SLE treatments at the ingredient level. For all continuous variables, mean with standard deviation and median with interquartile range will be reported. For all categorical analyses, number and percentages will be reported. A minimum cell count of 5 will be used when reporting results, smaller counts reported as 5.
