Patients presenting to emergency departments (EDs) with suspected pulmonary embolism (PE) can be risk stratified and those who are deemed to be at low risk for PE usually undergo D-dimer testing. A negative D-dimer in this low-risk group rules out PE with a high degree of certainty because of its high sensitivity. The D-dimer is, however, a poorly specific test and positive results often lead to unnecessary radiological imaging (notably computed tomography pulmonary angiography). The Pulmonary Embolism Rule-Out Criteria (PERC) rule has been suggested as an alternative to D-dimer testing in these patients. This study looked at whether the PERC rule could safely replace the use of D-dimer in patients suspected of PE, but deemed 'PE unlikely' by the dichotomized Wells score in a UK ED setting. ⋯ The PERC rule has a high negative predictive value for excluding PE in patients presenting with suspected PE to the ED. However, the PERC rule may still miss around 8% of confirmed PE in patients who are deemed 'PE unlikely' by a dichotomized Wells score. Caution is advised in using the PERC rule as a substitute for the standard D-dimer test in all these patients.

Rapid sequence intubation and emergency intubation in the emergency department (ED) can be life-saving procedures, but require the appropriate skills, experience and preparation to avoid complications ranging from simple trauma to life-threatening desaturation. Only scarce data exist in the published literature on complications following emergency intubation in children and most guidelines are extrapolated from the adult population. ⋯ Complications of rapid sequence intubation, a relatively low-frequency procedure in the paediatric ED, occurred in one of four children and repeat attempts at intubation were made in another 24%. We suggest that the use of an intubation checklist including the preparation of equipment and recommendations for drug use would minimize the occurrence of adverse events of intubation in children.

The Emergency Heart Failure Mortality Risk Grade (EHMRG) scale, derived in 86 Canadian emergency departments (EDs), stratifies patients with acute-decompensated heart failure (ADHF) according to their 7-day mortality risk. We evaluated its external validity in a Spanish cohort. ⋯ The EHMRG scale stratified risk in an ADHF cohort that included both palliative and nonpalliative patients in Spanish EDs, showing an extrapolation to a higher mortality risk cohort than the original derivation sample. Stratification improved when the score was recalibrated in the Spanish cohort.

We aimed to evaluate the impact of the same-day GPs' strike and terrorist attacks on a call centre's activity. ⋯ The GPs' strike and the terrorist attacks did not impact our call centre's activity in the same manner. The strike increased the number of PMFs without increasing the number of calls received. The attacks increased the number of calls received and MICU dispatched without increasing the number of PMFs. Many markers are at the disposal of call centres to evaluate the impact of healthcare events.

Despite the universal acknowledgment that triage is necessary to prioritize emergency care, there is no review that provides an overview of triage tools evaluated and utilized in resource-poor settings, such as low- and middle-income countries (LMICs). We seek to quantify and evaluate studies evaluating triage tools in LMICs. ⋯ The quality of evidence supporting any single triage tool's validity and reliability in LMICs is moderate at best. Research on triage tool applicability in low-resource environments must be targeted to the actual clinical environment where the tool will be utilized, and must include low-income countries and rural, primary care settings.
