Diagnosing acute heart failure (AHF) is difficult in elderly patients presenting with acute dyspnea to the emergency department. ⋯ In this study, NT-proBNP alone exhibited the best diagnostic accuracy for diagnosing AHF in elderly patients presenting with acute dyspnea to the emergency departments. None of the other biomarkers alone or combined improved the accuracy compared to NT-proBNP, which is the only biomarker to use in this setting.

Carbon monoxide (CO) poisoning is one of the most common causes of poisoning death and its diagnosis requires an elevated carboxyhemoglobin (COHb) level. Noninvasive CO saturation by pulse oximetry (SpCO) has been available since 2005 and has the advantage of being portable and easy to use, but its accuracy in determining blood COHb level is controversial. To evaluate the accuracy of SpCO (index test) to estimate COHb (reference test). ⋯ The mean bias was 0.75% and the LOA was -7.08% to 8.57%, 95% CI (-8.89 to 10.38) (2794 subjects and 4646 observations). Noninvasive measurement of COHb (SpCO) using current pulse CO oximeters do not seem to be highly accurate to estimate blood COHb (moderate sensitivity and specificity, large LOA). They should probably not be used to confirm (rule-in) or exclude (rule-out) CO poisoning with certainty.

Procedural sedation is routinely performed for procedures in the emergency department (ED). Propofol is a commonly used sedative, frequently combined with an opioid or low-dose ketamine as an analgesic. However, there is still controversy on the optimal combination of agents in current guidelines. ⋯ Two studies showed significant differences of overall sedation events in the fentanyl group. One study did not find any significant differences of the incidence of sedation events. This systematic review did not provide sufficient evidence that the combination of low-dose ketamine and propofol is associated with a shorter recovery time and fewer sedation events compared to the combination of opioids and propofol.

Patient safety in emergency departments: a problem for health care systems? An international survey.
Patient safety in healthcare is one of the cornerstones of quality of care. The emergency department (ED) is by its very nature a place where errors and safety issues are liable to occur. ⋯ This survey highlighted that most health professionals identify the ED as an environment with specific safety issues. The main factors appeared to be a shortage of personnel during busy periods, overcrowding due to boarding, and a perceived lack of support from hospital management.
