  1. Surveillance of influenza in Wales : interpreting sentinel general practice rates using contemporaneous laboratory data. Opportunities and limitations.

    Article, Communication - En anglais

    Hannover Sentinel Workshop. Hannover, DEU, 1996/03/01.

    Objectives-To evaluate the opportunities and limitations of using laboratory data to enhance sentinel general practice surveillance of influenza.

    Design-Descriptive study of active sentinel surveillance of clinically diagnosed influenza in general practice and passive total population surveillance of laboratory reports of influenza A, influenza B, Mycoplasma pneumoniae, and respiratory syncitial virus infections.

    Setting-Wales

    Subjects-Total sentinel practices population (currently 228 130) ; population of Wales (2 913 000,1994 mid-year estimate).

    Main outcome measures-Simplicity, flexibility, acceptability, sensitivity, predictive value positive, representativeness, and timeliness of a surveillance system.

    Rate of influenza and other respiratory infections.

    Results

    Sentinel general practice surveillance of influenza in Wales is simple, flexible, acceptable, timely, representative, and relatively sensitive.

    Current laboratory surveillance is complex and less timely than sentinel practice surveillance but is complete and has a relatively high positive predictive value.

    For the period January 1993 to September 1996, peaks in rates of influenza reported by sentinel practices during winters 1993/94 and 1995196 were temporally associated with increased rates of laboratory confirmed influenza A and respiratory syncitial virus, whereas the peak in 1994/95 was associated with increased rates of laboratory confirmed influenza B, M pneumoniae, and respiratory syncitial virus.
