OBJECTIVE To measure the time spent authoring and viewing documentation and to study patterns of usage in healthcare practice. DESIGN Audit logs for an electronic health record were used to calculate rates, and social network analysis was applied to ascertain usage patterns. Subjects comprised all care providers at an urban academic medical center who(More)
Much of what is currently documented in the electronic health record is in response toincreasingly complex and prescriptive medicolegal, reimbursement, and regulatory requirements. These requirements often result in redundant data capture and cumbersome documentation processes. AMIA's 2011 Health Policy Meeting examined key issues in this arena and(More)
— In resource-limited mobile computing devices, Blue-tooth wireless technology imposes a weighty burden due to inef-£cient power utilization and a sluggish device discovery process. Buttressing Bluetooth with Radio Frequency Identi£cation (RFID) technology by performing an operation we call " Rendez-Blue " alleviates these limitations. In the Rendez-Blue(More)
OBJECTIVE To evaluate the data quality of ventilator settings recorded by respiratory therapists using a computer charting application and assess the impact of incorrect data on computerized ventilator management protocols. DESIGN An analysis of 29,054 charting events gathered over 12 months from 678 ventilated patients (1,736 ventilator days) in four(More)

MATERIALS AND METHODS Time-and-motion study of resident physicians' note-writing practices using a commercial(More)
We demonstrate the integration of a longitudinal, internally-developed legacy clinical information system with a vendor-based electronic health record application. The expense of developing the interface across systems was minimal, and it was successfully incorporated within the vendor EHR. Users consistently used the legacy data view while using the EHR;(More)
