Prioritisation of infectious diseases in public health: feedback on the prioritisation methodology, 15 July 2008 to 15 January 2009

In 2004, the German public health institute, the Robert Koch Institute (RKI), prioritised pathogens by public health criteria and presented the methodology and findings. In order to further improve the methodology, the RKI invited experts to give feedback on this via a structured web-based questionnaire. The survey was completed by 72 participants during 15 July 2008 to 15 January 2009. Prioritisation of pathogens was considered as useful for public health purposes by 68 participants and for both surveillance and epidemiological research by 64 participants. Additional pathogens were suggested, including some that are resistant to antimicrobials. The criteria incidence, severity, outbreak potential, emerging potential and preventability were each considered as useful or very useful for the prioritisation (by more than 65 participants for each criterion). Weighting of the criteria was judged as relevant or very relevant by 67 of participants, but needs more explanation. It was also suggested that the group carrying out the prioritisation be composed of a median of 15 experts (range: 5-1,000). The feedback obtained in the survey has been taken into account in the modification of the methodology for the next round of prioritisation, which started in December 2010. .
