Medical Device Clock Errors
Unlike your cell phone or computer, most medical devices do not set their clocks using a network time reference. Like an old-fashioned VCR, the clocks are typically set manually twice a year for daylight savings time, or when the medical devices are serviced.
The absence of automatic clock-setting capabilities in most devices—and the lack of time synchronization among the wide array of different medical devices used in a typical hospital—can result in inaccurate time-stamps of clinical data recorded in the electronic medical record (EMR). These inaccuracies also complicate the synchronization of data from multiple devices when analyzing adverse events.
There is no widely adopted standard for medical device time management and no implementation guidelines are available. Therefore, we are studying this problem and potential solutions.
Research Studies
Two studies are in progress – one to study the extent of the problem by documenting medical device clock errors in hospitals, and the second study to assess the personnel workload/cost required to manually perform DST clock-changes. These studies are being funded by NIH/NIBIB and DoD/TATRC.
Survey on Medical Device Clock Synchronization Issues
We have developed a survey that was distributed to the healthcare technology management field. See details of the survey in the article on the AAMI website.
