To analyze whether short-term outcomes are affected when patients diagnosed with acute heart failure (AHF) spend time in an emergency department observation unit (EDOU) before hospital admission. ⋯ Although mortality higher in patients hospitalized for AHF who spend time in an EDO, the association seems to be accounted for by their worse baseline situation and the greater seriousness of the decompensation episode, not by time spent in the EDOU.

Multicenter Study Observational Study
Derivation and validation of new prehospital phenotypes for adults with COVID-19.
To characterize phenotypes of prehospital patients with COVID-19 to facilitate early identification of at-risk groups. ⋯ Patients with COVID-19 evaluated by emergency medical responders and transferred to hospital emergency departments can be classified into 4 phenotypes with different clinical, therapeutic, and prognostic characteristics. The phenotypes can help health care professionals to quickly assess a patient's future risk, thus informing clinical decisions.

To analyze the association between blood pressure during vasopressor weaning and in-hospital mortality in patients admitted to an intensive care unit (ICU). ⋯ Higher blood pressures during vasopressor weaning are associated with longer in-hospital survival in ICU patients. The optimum pressure ranges are SBP, 110-150 mmHg; DBP, 60-85 mmHg; and MAP, 75-110 mmHg. Blood pressures may behave differently according to diagnosis.

Observational Study
Safety of ketamine for reducing fractures in a pediatric emergency department.
Ketamine is one of the most widely used drugs for analgesia and sedation when reducing fractures in pediatric emergency departments (EDs). We aimed to analyze the safety of intravenous (IV) ketamine when administered by physicians who are not anesthesiologists. ⋯ Pediatric emergency physicians who are not anesthesiologists can safely administer IV ketamine for reducing fractures. Prior use of opioids is not associated with greater risk for respiratory AEs after ketamine use.
