Hypothesis

Can syndromic ILI data be extracted automatically from routine GP data?

Conclusion

Automated data extraction from routine GP records offers a means to gather data without introducing any additional work for the practitioner.

Supporting Evidence

  • The Canning Flu Tool identified seasonal trends in ILI both retrospectively and in near real-time.
  • The sensitivity of the tool was 96.3% and the specificity was 99.7%.
  • The GP surveillance tool produced a more robust signal than the existing PHREDSS system.

Takeaway

This study shows that we can use computers to automatically collect information about flu-like illnesses from doctors' records, making it easier to track flu trends.

Methodology

The study adapted a software program for automated data extraction from GP records and compared ILI data from GP practices with emergency department data.

Potential Biases

The sensitivity of the tool might be lower in practices using certain medical record software that encrypts progress notes.

Limitations

The study was conducted in a metropolitan area with relatively high socioeconomic status, limiting generalizability.

Participant Demographics

The study involved eight GP sites in a metropolitan area of Sydney, Australia.
