- 1. Julien Beauté, ECDC Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014 Evaluation of severe influenza surveillance in Europe
- 2. Background • 2009 influenza pandemic − First attempt to monitor severe cases at EU level − Rapid development of surveillance – July 2009 • 2010-to the present date − Six to ten EU/EEA countries reporting (seven for the 2013/14 season) − Thirteen countries reported SARI data to EuroFlu for the 2013/14 season (including two EU countries) − Cases admitted to intensive care units or any ward − Sentinel or comprehensive surveillance Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
- 3. Outputs Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014 • Weekly influenza bulletins • ECDC seasonal risk assessment • Annual reports • Peer-reviewed publications
- 4. Evaluation of severe influenza surveillance • To provide ECDC with: − Clear statement on epidemiological and public health usefulness − Future scenarios and recommendations • Requested deliverables: − Description of the surveillance of severe influenza in all the EU/EEA states − Review of the surveillance at the EU/EEA level − Comparison with systems elsewhere − Guidance for future Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
- 5. Evaluation of severe influenza surveillance • Findings: − Heterogeneity of systems in place hinders any significant added value from an European perspective − Example of federally organised countries (e.g. U.S.) strongly argues in favour of more harmonised systems Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
- 6. Key features of severe influenza surveillance systems in EU/EEA countries Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
- 7. 37th ECDC Advisory Forum, 27 Feb 2014 • Options − Abandon severe influenza surveillance − Proceed with the current strategy aiming at improving harmonisation and increasing the number of participating countries − Proceed with the current system, but restrict severe influenza surveillance to intensive care units − Establish a new surveillance system based on a European network of sentinel hospitals − … Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
- 8. Recommendations • 37th ECDC Advisory Forum, 27 Feb 2014 – Proceed with the current system, but restrict severe influenza surveillance to intensive care units – Clarify the objectives of severe influenza surveillance at the European level • EISN Coordination Committee meeting, 19 Mar 2014 – Convince countries collecting data to participate – Agree on denominator data – Explore alternative monitoring systems – Estimate risk factors for severe disease Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
