Viboud, C., Charu, V., Olson, D., et al. (2014). Demonstrating the Use of High-Volume Electronic Medical Claims Data to Monitor Local and Regional Influenza Activity in the US. PLoS One. 9(7).
Using electronic medical claims data from 2003 to 2010, the authors found that influenza-like illness indicators accurately reflected weekly fluctuations in influenza activity. They suggest that electronic medical claims data can supplement surveillance systems and can be used to provide situational awareness, refine influenza transmission models, and support future pandemic responses.
