Summary: This study compared the frequency and types of errors and adverse events attributed to emergency medicine residents and attendings using an integrated electronic error reporting system. The results showed that resident errors were mainly related to treatment interventions and reflected concomitant errors on the part of attendings. Adverse events were more likely to be attributed to attendings rather than residents.

Summary: The study shows that the clinical decision unit (CDU) in the emergency department can significantly reduce unnecessary hospitalizations and wrongful patient discharges. CDU is particularly beneficial for high-risk patients, but there is a critical trade-off in resource allocation and congestion between the two gatekeeping stages. In this specific case, it is found that reducing the size of the first-stage ED to expand CDU capacity could further reduce unnecessary hospitalizations.

Summary: Patients discharged to home after an emergency department visit for headache face a heightened risk of stroke, three to four times higher than the risk associated with renal colic or back pain.

Summary: This study found that 0.6% of patients with emergency department visits for headaches were subsequently hospitalized for cerebrovascular disease, often at a different medical center. Patients with a history of stroke or neurosurgery prior to the visit may represent important opportunities for cerebrovascular disease prevention. Poor documentation of neurological examinations among cases suggests a potential need for improvement in emergency department processes.

Summary: This paper introduces a three-layer BP neural network model for quantitatively estimating the probability of unsafe events in air traffic control departments, and proposes a new mapping method to address the issue of large difference in desired outputs between unsafe events and safe events during training.

Summary: An observational study on the usage of an electronic diagnosis generator (EDG) in a high-acuity area of a tertiary care emergency department showed that it can play a role in improving diagnosis and guiding diagnostic testing for critically ill patients, especially for cases with uncertainty.

Summary: This study developed and tested a modified version of a medical record review tool to identify FNS in hospitalized stroke patients and gain insight into the sources of ED misdiagnosis. The most common sources of error identified were too narrow a differential diagnosis and limited neurological examination. The Safer Stroke-Dx Instrument was found to be a reliable tool for identifying FNS and sources of diagnostic error.

Summary: This study aimed to estimate the misdiagnosis rate of PRES/RCVS in the emergency department and its associated factors. The study found that approximately one in twenty patients with PRES/RCVS in a large, multistate cohort may experience misdiagnosis in the emergency department. Misdiagnosed patients were typically younger, more often female, and had comorbidities such as headache and substance use disorder.

Summary: This study examined the association between short-term ambient air pollution exposure and emergency department visits for asthma in the United States. The results showed that air pollution exposure was positively associated with increased rates of asthma ED visits. The effects of air pollution were more pronounced in children and older populations.

Summary: The study reveals that in the emergency department, the majority of patients receiving ketamine doses were below 50 mg, suggesting that a product with 50 mg in 1 mL may be most appropriate.

Summary: This paper conducts an error analysis for a new five-degree-of-freedom hybrid robot and identifies the compensable and non-compensable error sources affecting its posture error. The results show that the dynamic and fixed platform hinge position error has the most significant effect on the end of the robot. When designing this hybrid robot, attention should be paid to the manufacturing and installation accuracy of the dynamic and fixed platform hinge point positions and the translational joint initial position.

Summary: This study investigated medication errors in antibiotic prescriptions for pediatric patients discharged from a pediatric emergency department. The study found a total of 1986 errors, with underdosing being the most common error. The study suggests the need for further research and strategies utilizing technology, education, and pharmacy personnel to reduce antibiotic prescribing errors for discharged patients.

Summary: This study investigates the rate and factors associated with unplanned return visits (uRVs) within 48 hours in a pediatric emergency department. The results show that patients with triage category 3, aged between 3 months and 5 years, and presenting with infectious illnesses are more likely to have uRVs. Seasonal variation and doctor changeover also contribute to higher uRV rates.

Summary: This study characterized errors in the care of surgical patients and found an association between errors and postoperative morbidity, especially technical errors. The results of the study revealed a strong independent relationship between errors and morbidity.
