Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will assess the burden of influenza by age, risk status, vaccination status and influenza subtype, in order to create a complete profile of the burden of influenza-related morbidity and mortality in United Kingdom from 1996 to 2008.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This epidemiological study is a modelling of time series retrospectively extracted from multiple databases. The data collection will be a query of existing electronic healthcare databases.

Data collection

Intervention Type OTHER

The study, will use four primary data sources: the General Practice Research Database (GPRD, for mild outcomes), the Hospital Episode Statistics database (HES, for hospitalizations), the Office of National Statistics mortality database (ONS, for mortality), and weekly virology data from the Health Protection Agency (HPA).

Weekly time series of the rates of various influenza-related health outcomes in the various databases, such as office visits for acute otitis media and hospitalizations for pneumonia will be constructed. Statistical models, guided by weekly numbers of cases of laboratory-confirmed influenza and respiratory syncytial virus (RSV) contained in the HPA virology data, to estimate the portions of the various outcomes that can be attributed to influenza will be constructed. Finally, the seasonal impact of influenza by risk status, vaccination status, and seasons in which a well-matched versus mismatched influenza vaccine was used, will be assessed.
