Quantifying the electronic medical record implementation to stabilization curve.

140Background: The implementation of electronic medical records (EMR) has been noted to disrupt clinical workflows as providers acclimate to a new EMR. On May 30, 2015, Dana-Farber Cancer Institute (DFCI) implemented a new EMR. Using our Real Time Location System (RTLS), we sought to identify the time required to stabilize the experience for providers. We identified factors that may speed the stabilization rate to guide EMR implementations elsewhere. Methods: DFCI uses an RTLS to timestamp patient and provider locations throughout the day. To adjust for variation in appointment types, we measured the ratio of the actual exam duration (recorded by the RTLS) to the scheduled exam duration. We compared to a 3-month baseline average to quantify the immediate impact of implementation. We tracked the ratio over time to identify when stabilization occurred and compare to baseline performance. To infer influential factors, we performed a regression analysis based on RTLS data from the first 6 months post implemen...
