Inappropriate antibiotic prescribing can result in patient harm and costly antibiotic-resistant infections. Health record review of 1,477 patients admitted from the emergency department for suspected bacteremia infection revealed that 11.6% were misdiagnosed at infection site, and 3.1% did not have any infection. Misdiagnosis was not associated with worse short-term clinical outcomes but was associated with potentially inappropriate broad-spectrum antibiotic use.

This mixed-methods study analyzed patient safety incident reports between 2005-2015 to characterize the most frequently reported incidents resulting in severe harm or death in acute medical units. Of the 377 included reports, diagnostic errors, medication-related errors, and failure to monitor patient incidents were most common. Patients were at highest risk during handoffs and transitions of care. Lack of active decision-making during admission and communication failures were the most common contributors to incidents.
Much of the evidence about preventable harm in patients with psychiatric illnesses is limited to inpatient psychiatric facilities. This case-control study explores patient-related factors that place patients at an increased risk for patient safety incidents in primary or emergency care. While differences in income, education, and foreign background had some association with preventable harm, researchers found that psychiatric illness nearly doubled the risk of preventable harm among both emergency and primary care patients, with nearly half (46%) of harm attributable to diagnostic errors.

Many adverse event identification methods cannot detect errors until well after the event has occurred, as they rely on screening administrative data or review of the entire chart after discharge. Electronic medical records (EMRs) offer several potential patient safety advantages, such as decision support for averting medication or diagnostic errors. This study, conducted in the Veterans Affairs system, reports on the successful development of algorithms for screening clinicians' notes within EMRs to detect postoperative complications. The algorithms accurately identified a range of postoperative adverse events, with a lower false negative rate than the Patient Safety Indicators. As the accompanying editorial notes, these results extend the patient safety possibilities of EMRs to potentially allow for real time identification of adverse events.

Reflection, or thinking about thinking, is often used as a technique to encourage learning from adverse events. This study describes the development and pilot testing of a case-based system to encourage and measure reflection among faculty physicians at an academic medical center.

Emergency department (ED) patients are particularly vulnerable to adverse events, and a prior study of closed malpractice claims implicated systems factors such as poor teamwork in adverse patient outcomes. This study used root cause analysis of incident reports to identify the types and causes of errors and unanticipated events in the ED. Incidents included poor communication and teamwork, particularly with other departments, but medication errors and diagnostic errors were also noted. The authors recommend that organizations integrate the ED into hospital-wide safety improvement efforts.
