• Study description:
  This non-interventional study is designed to investigate the effectiveness of OM-85 in the prevention of Respiratory Tract Infection (RTI) episodes and to understand the management of patients with RTI. The objectives will be studied separately in Belgium, Italy and China and will include description and comparison of RTI episodes before and after initiating OM-85 treatment, comparison of RTI episodes in patients initiating OM-85 treatment and in a non-user group, pattern of prescription of OM-85, antibiotics and other concomitant medications of interest, and healthcare resource utilisation. ; ; As primary objectives, the effectiveness of OM-85 is assessed through (1) a before-after design, comparing the rate of RTI episodes before and after initiation of OM-85, and (2) a comparative effectiveness design, comparing the rate of RTI episodes during follow-up between patients who initiated OM-85 and patients who did not initiate OM-85.; ; The Target Trial Emulation is used as the framework for the design of this non-interventional study. ; The study period will start from the date of earliest data availability and end at the date of latest data availability in each of the data sources. The study period will include an inclusion period, a baseline period, an initiation grace period and a follow-up period. The outcomes will be assessed at 3, 6, 9, 12, and 24 months after the initiation grace period, as per data availability. ; ; The overall study population will include patients aged ≥ 1 year of age with ≥1 RTI episodes and no prescriptions of bacterial lysates within 12 months prior to the inclusion (baseline period).
