Burden of Respiratory Syncytial Virus (RSV) in the United Kingdom From 1995 to 2009

Study Overview
=================
Brief Summary
-----------------
The study will assess the burden of RSV-attributable general practice consultations, hosptializations, and deaths by age and risk group in in United Kingdom from 1995 to 2009.

Detailed Description
-----------------
This epidemiological study is based on an already existing database of time series regression modeling outputs generated during the generated by EPI-FLU-018 BOD UK DB (116273) study, which estimated the burden of influenza in terms of General Practitioner (GP) consultations, hospitalizations, and deaths associated with various respiratory and non-respiratory outcomes.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Cohort Group<br> | Other: Data collection<br>* The previous study has used four primary data sources: the General Practice Research Data (GPRD [recently re-named Clinical Practice Research Datalink (CPRD)], 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). The extracted data are referred to as the EPI-FLU-018 BOD UK DB database. Weekly time series will be generated to estimate the RSV burden and characterize it in terms of incidence of GP consultations, hospitalizations and deaths for each of the respiratory and non-respiratory outcomes (including GP antibiotic prescriptions), stratified by age and risk group.<br>|

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Occurrence in the EPI-FLU-018 BOD UK DB results database of potentially RSV-attributable GP consultation, hospitalization or death associated with respiratory outcomes. |  | From 1995 to 2009 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Occurrence in the EPI-FLU-018 BOD UK DB results database of potentially RSV-attributable GP consultation, hospitalization or death associated with non-respiratory outcomes. |  | From 1995 to 2009 | 
| Occurrence in the EPI-FLU-018 BOD UK DB results database of potentially RSV-attributable GP prescription of antibiotics relevant to respiratory disease, by age and risk group. |  | From 1995 to 2009 | 
| Peak occurrence of potentially RSV-attributable hospitalizations and deaths in elderly and pediatric populations. |  | From 1995 to 2009 | 
| Occurrence of potentially RSV-attributable deaths among the total number of RSV-attributable hospitalizations and cases, by age and risk group. |  | From 1995 to 2009 |
