The safety of electronic prescribing: manifestations, mechanisms, and rates of system-related errors associated with two commercial systems in hospitals.
Approach to Improving Safety
Setting of Care
The Institute of Medicine highlighted the challenges of health information technology implementation in their 2011 report, Health IT and Patient Safety. A growing list of unintended consequences from computerized provider order entry (CPOE) systems has emerged over the last few years. This study describes a robust classification structure for identifying systems-related errors in CPOE programs. Two hospitals with different CPOE systems were examined. Systems-related errors were found to be frequent, comprising 42% of all prescribing errors, although only 2.2% were serious errors. Both CPOE systems in this study prevented many more prescribing errors than they created, supporting the overall benefit of CPOE for patient safety. An AHRQ WebM&M perspective discussed CPOE and medication safety.
