Summary

The study will assess the burden of severe influenza outcomes by age, risk status, and influenza subtype, in order to create a profile of the burden of influenza-related morbidity and mortality in United States from July 1997 to April 2009.

Data collection

The study will use multiple primary data sources: the Nationwide Inpatient Sample (for hospitalisations) and the US National Vital Statistics System (for mortality), and weekly virology data from the Centers for Disease Control and Prevention (CDC) influenza surveillance program supplemented with literature data. Weekly time series of the rates of various severe influenza-related health outcomes will be constructed. Statistical models, guided by weekly numbers of cases of laboratory-confirmed influenza and respiratory syncytial virus (RSV) contained in the CDC virology data, will be constructed to estimate the portions of the various outcomes that can be attributed to influenza. Next, the seasonal impact of influenza by age, risk status, and influenza subtype will be assessed. Finally, the potential burden that a quadrivalent vaccine could have prevented over the 12 year study period will be predicted.
