Risk of Wrong-Patient Errors With Multiple Records Open

This study is designed to achieve the following aims: 1. Assess the relationship between the number of records open at the time of placing an order, and the risk of placing an order on the wrong patient. 2. Compare the incidence of wrong-patient orders in a "restricted environment" that limits its providers to only one record open at a time to an "unrestricted environment" where users can open a maximum of four records at once. 3. The results of this study will help inform decisions on how to safely implement EHR systems. 4. The results of this study will inform a larger scale health IT implementation research project evaluating the balance between the wrong-patient error risks and potential efficiency gains of having multiple records open at once, with rigorous research methodologies.
