Measuring adverse events in hospitalized patients: an administrative method for measuring harm.
Approach to Improving Safety
Setting of Care
Patient safety problems can be difficult to detect. This study used electronic health record data—such as diagnostic codes, laboratory test values, and pharmacy information—to identify adverse events in an automated fashion. The authors conclude that the administrative harm measurement tool can detect adverse events accurately enough for internal quality improvement purposes, but the tool is insufficient to compare harm across institutions.
