Emergency care staff wearing elastomeric respiratory personal protective equipment (PPE) report difficulties in communicating by telephone. We developed and tested an affordable technological solution aimed at improving telephone call intelligibility for staff wearing PPE. ⋯ Introduction of a suitable headset could significantly improve speech intelligibility during 'emergency alert' telephone calls.

Currently, there is no consensus on the number of defibrillation attempts that should be made before transfer to a hospital in patients with out-of-hospital cardiac arrest (OHCA). This study aimed to evaluate the association between the number of defibrillations and a sustained prehospital return of spontaneous circulation (ROSC). ⋯ We observed no significant increase in ROSC after five defibrillations, and no absolute increase in ROSC after seven defibrillations. These data provide a starting point for determination of the optimal defibrillation strategy prior to consideration for prehospital extracorporeal cardiopulmonary resuscitation (ECPR) or conveyance to a hospital with an ECPR capability.

The Manchester Acute Coronary Syndromes ECG (MACS-ECG) prediction model calculates a score based on objective ECG measurements to give the probability of a non-ST elevation myocardial infarction (NSTEMI). The model showed good performance in the emergency department (ED), but its accuracy in the pre-hospital setting is unknown. We aimed to externally validate MACS-ECG in the pre-hospital environment. ⋯ Neither MACS-ECG nor paramedic ECG interpretation had a sufficiently high PPV or NPV to 'rule in' or 'rule out' NSTEMI alone.

Upper gastrointestinal bleeding (UGIB) is a medical emergency with an approximate mortality of 10%, which results in a high hospitalisation rate. The Glasgow-Blatchford score (GBS) is recommended to identify low-risk patients who can be discharged from the emergency department (ED). A modified GBS (mGBS) and CANUKA score have recently been proposed but have not been well studied. The aim of this study was to assess whether the use of GBS, mGBS or CANUKA score could identify patients at low risk of death or need for intervention. ⋯ In patients with UGIB, the use of a GBS≤1 or CANUKA score ≤2 appears to be safe for identifying patients at low risk of death or need for intervention.
