The increasing threat of infections with pandemic potential such as influenza has focussed attention on the information needed to inform those managing a pandemic. The Health Protection Agency, Nottingham University and EMIS have developed a new national health protection surveillance system using QRESEARCH, an established primary care-derived database, to provide timely and local information on trends in community illness and prescribing. This article describes the first year of the surveillance project. Data on consultations and prescribing were extracted from routinely generated computerized consultation records between November 2004 and December 2005. Weekly consultation and prescribing rates for a range of conditions including influenza-like illness and prescription of anti-viral drugs for influenza and vomiting were developed as key indicators. These indicators were presented in a weekly bulletin showing data to strategic health authority level for use by those working in public health. The particular value of this scheme is the ability to produce timely data on illness to local level and to link prescribing to morbidity. The data were used real time to reassure about lack of illness following the Buncefield Fuel Depot incident. This scheme is being further developed to provide daily local influenza-related information needed in an influenza pandemic.
