The impact of electronic medical records on hospital-acquired adverse safety events: differential effects between single-source and multiple-source systems.
Approach to Improving Safety
Setting of Care
Electronic health records enhance patient safety, but they also have unintended consequences. This retrospective study found that hospitals with a single-source electronic health record were less likely to have hospital-acquired safety events compared to hospitals with multiple systems in place. These results suggest that safety gaps may arise at the interface of multiple electronic systems.
