The Impact of Electronic Medical Records on Hospital-Acquired Adverse Safety Events: Differential Effects Between Single-Source and Multiple-Source Systems

The objective was to examine differential impacts between single-source and multiple-source electronic medical<br>record (EMR) systems, as measured by number of vendor products, on hospital-acquired patient safety events. The<br>data source was the 2009-2010 State Inpatient Databases of the Healthcare Cost and Utilization Project for California,<br>New York, and Florida, and the Information Technology Supplement to the American Hospital Association’s Annual<br>Survey. Multivariable regression analyses were conducted to estimate the differential impacts of EMRs between singlesource<br>and multiple-source EMR systems on hospital-acquired patient safety events. In all, 1.98% of adult surgery<br>hospitalizations had at least 1 hospital-acquired patient safety event. Basic EMRs with a single vendor or self-developed<br>EMR systems were associated with a significant decrease in patient safety events by 0.38 percentage point, or 19.2%,<br>whereas basic EMRs with multiple vendors had an insignificant association. A single-source EMR system enhances the<br>impact of EMRs on reducing patient safety events.
