Genes, N., Chary, M., and Chason K. (2013). An Academic Medical Center's Response to Widespread Computer Failure. American Journal of Disaster Medicine. 8(2):145-50.
The authors describe the disruption of the computer systems at Mount Sinai Medical Center in New York City on a single day, the hospital's response to the event, and subsequent modifications to emergency plans incorporating lessons learned. They found that departments that utilized a combination of electronic and paper systems were impacted less than the Emergency Department, which was completely reliant on electronic medical records.
