“Electronic Health Record (EHR) systems can serve as rich data sources to examine clinical workflow. We extracted event logs for every encounter that took place in an academic hospital emergency department and its satellite urgent care sites in 2013. We identified delays between the occurrence and the recorded times of care delivery activities. Workflow researchers should consider these delays to ensure event sequences are captured accurately when using EHR systems as a data source.

Methods
We extracted event logs for each encounter that took place in the emergency department (ED) of an academic hospital and its satellite urgent care sites in 2013. Our analysis included a total of 2,815,568 events from 133,586 visits by 88,936 patients. Data extraction included the following data elements: activity type, activity occurrence and activity recording times. Activity occurrence is the time that is displayed in the EHR as the time the event occurred, which may be changed manually by a staff member for some events. Activity recording time is the timestamp in the system when the information was recorded.

[Process mining!]”
