Can EHRs power up the fight against epidemics? | healthcare technology | Scoop.it

Government health IT leaders say electronic health record systems can expand information sharing and help public health responders fight the spread Ebola and future viruses.


While the United States avoided a public health crisis from the Ebola virus, the possibility of an epidemic at home got government health IT leaders thinking about how electronic health records might be used to expand information sharing and help public health responders fight the spread of Ebola and future viruses.


There are significant hurdles to clear before the EHRs used in clinical care will be able to really help state, local and federal health officials track and respond to fast-moving outbreaks in real time, according to those at recent Health IT Policy Committee meeting on the potential for using EHRs to fight epidemics.


The problem of interoperability and data transfer between EHR systems, medical laboratories and public health databases is one big issue. More broadly, there is a lack of what experts call "bidirectionality" between health records, preventing health officials – either for technical or privacy reasons – from accessing individual patient records.


Ultimately, broader use of EHRs to detect and respond to epidemics will require changes in technology. The passive surveillance of patient EHRs using analytic tools could give greater velocity to detecting not just viral disease outbreaks, but environmental risks, contaminated food and medicine as well as other large-scale health problems that are clustered geographically or in certain demographic groups.


That’s not to say epidemiology is lacking in high-tech approaches. New York City, for example, was able to use cell phone location information and subway fare card data to conduct contact tracing on individuals that may have come into contact with the Ebola virus while traveling. However, aggregating that information, and making it available at scale through an EHR platform, appears to be a long way off.
