About the report Winter focus The first two pages of data within this report focus on Influenza-Like Illness, in order to provide information about the on set of seasonalinfluenza and early warning of any epidemic. Rate calculation Each weekly incidence rate is presented per 100,000 population. All presentations are for males and females, and for all age groups,unless otherwise stated. The denominator used for this report is taken from our most recent extract of data from GP practice systems, and includes all patientscurrently registered with eligible practices. The denominator varies week-on-week as patients register and deregister; it may also be thecase that all patients from an individual practice are excluded because of problems with the data extraction from that practice in a spe-cific week. As stated above, patients who have withheld consent for data-sharing are excluded. In addition to the national rate, we present data for the four NHS England regions: North; Midlands and East; South; and London. Five-year averages Weekly rates are set against the five-year average, calculated from data for the calendar years 2012-2016. Previously we reportedagainst a ten-year average. The change to a five-year average was made because longer-term trends in the incidence of disease haveled to weekly rates for certain diseases becoming increasingly divergent from their ten-year average. The use of five-year averageslessens this effect and enables more meaningful comparison. Threshold calculation for Influenza-Like Illness (ILI) We are now using the Moving Epidemic Method (MEM) to calculate threshold and intensity levels for Influenza-Like Illness. MEM worksby identifying seasonal epidemic peaks and then calculates thresholds and intensity levels based on the pre and post epidemic values.This allows us to report the severity of ILI against multiple thresholds, rather than a simple comparison with the five-year average as thewide variation in ILI year on year, especially during the seasonal peak, makes the average less representative. In addition to the All Ages thresholds, we have also calculated thresholds for three age bands: those aged under 15, 15-64 year oldsand those aged 65 and over. ILI incidence rates vary among different age groups, and the age-specific thresholds allow us to highlightepidemics where ILI disproportionately affects a particular age group. This methodology is used by the European Centre for Disease Prevention and Control to standardise reporting of influenza activityacross Europe, and is also in use by Public Health England. Full details of the methodology can be found in: Vega et al. (2012) Influen-za surveillance in Europe: establishing epidemic thresholds by the moving epidemic method. Influenza and Other Respiratory Viruses7(4), 546–558. For ease of graphical representation, the final threshold (Very High) is not included in Graph A, page 2, but it is part ofTable 3, page 3. Both the all-ages thresholds and the age-specific thresholds are shown in Table 2, page 3. Ten years of data were used for all-agesand age-specific thresholds calculation (winter seasons 2005/06- 2015/16 excluding 2009/10).

FURTHER INFORMATION:RCGP Research & Surveillance Centre - Weekly Returns Service
What we do The RCGP RSC was established in 1957, with the current name in use since 2009. The Centre is an internationally renowned source ofinformation, analysis and interpretation concerning the onset, patterns, prevalence and trends over time of morbidity in primary care.The RSC is an active research and surveillance unit that collects and monitors data; its most important research is the surveillance of influenza and the monitoring of vaccine effectiveness. The RSC data and analytics hub is housed in the Section of Clinical Medicine and Ageing at the University of Surrey. Further information about the RSC can be found on our website: Our data extraction process and information governance Data are extracted twice weekly from practice systems by Apollo Medical Software Solutions on the RCGP’s behalf. Patients who havewithheld consent for data sharing are excluded from the extraction process. Data are pseudonymised as close to source as possible. Data are held on secure servers at the RCGP data and analytics hub in theSection of Clinical Medicine and Ageing at the University of Surrey. Both Apollo and the University of Surrey are Registered and compliantwith the Data Protection Act and fully compliant with all relevant NHS Digital data information governance best practice. What the data is used for The RCGP RSC has been providing reports weekly about health and disease, called the Weekly Returns Service (WRS) since 1964.The WRS monitors the number of patients consulting with new episodes of illness classified by diagnosis in England and providesweekly incidence rates per 100,000 population for these new episodes of illness. It is the key primary care element of the national dis-ease monitoring systems run by Public Health England. The bulletin can be found at the following URL: In addition to the WRS, the data is used for other research studies. Any other uses of the data for research follow ethical approval oragreement from NIHR proportionate review, and where relevant Health Research Authority Confidential Advisory Group advice that fur-ther approval is not needed. Full details can be found on our website: For further information For further information about the work of the RSC, or if you would like to be included on our email notification list, please contact: RCGP Research & Surveillance Centre CIRC, First floor 30 Euston Square London NW1 2FB Tel: +44 (0)203 188 7690 Medical Director: Professor Simon de Lusignan [email protected]
