Study design details

Main study objective

To describe the rates of influenza and influenza like illness, including associated morbidity and mortality, among persons prescribed Xeljanz or other systemic therapies among cohorts of patients with RA, PsA and UC

Outcomes

To describe demographics, comorbidities and clinical characteristics of RA, PsA, and UC patient. To describe the frequency, incidence rates and clinical outcomes of influenza infections and influenza like illness and their complications.

Data analysis plan

Baseline demographics, comorbidities and clinical characteristics will be analyzed using baseline data for RA, PsA and UC patients, then stratified by index treatment and age. The frequency and incidence rates for influenza and influenza like illness among patients treated for RA, PsA, and UC in subsets of patients defined by different index treatments will be provided, the frequency of influenza complications, drug use around influenza diagnosis, influenza-related hospitalization and mortality among these patients will also be provided. By influenza season analysis will be performed when applicable.
