Improving out-of-hospital cardiac arrest (OHCA) prognosis within the working-age population is important, but no studies have investigated the effects of COVID-19 pandemic specifically on the working-age population with OHCAs. We aimed to determine the association between the 2020 COVID-19 pandemic and OHCA outcomes and bystander resuscitation efforts among the working-age population. ⋯ Reviewing automated external defibrillator (AED) locations and increasing BCPR through DAI-CPR may help prevent pandemic-associated decreases in survival rates for patients with cardiac OHCAs.

microMend, a novel microstaple skin closure device, may be able to close simple lacerations. This study aimed to evaluate the feasibility and acceptability of using microMend to close these wounds in the ED. ⋯ microMend appears to be an acceptable alternative for closing skin lacerations in the ED, providing good cosmetic results, with high levels of satisfaction by patients and providers. Randomised trials are needed to compare microMend with other wound closure products.

Observational Study
Role of hospital strain in determining outcomes for people hospitalised with COVID-19 in England.
In England, reported COVID-19 mortality rates increased during winter 2020/21 relative to earlier summer and autumn months. This study aimed to examine the association between COVID-19-related hospital bed-strain during this time and patient outcomes. ⋯ High levels of bed-strain were associated with higher in-hospital mortality rates, although the effect was relatively modest and may not fully explain increased mortality rates during winter 2020/21 compared with earlier months. Shorter hospital stay during periods of greater strain may partly reflect changes in patient management over time.

Plain radiographs cannot identify all scaphoid fractures; thus ED patients with a clinical suspicion of scaphoid injury often undergo immobilisation despite normal imaging. This study determined (1) the prevalence of scaphoid fracture among patients with a clinical suspicion of scaphoid injury with normal radiographs and (2) whether clinical features can identify patients that do not require immobilisation and further imaging. ⋯ No single feature satisfactorily excludes an occult scaphoid fracture. Further work should explore whether a combination of clinical features, possibly in conjunction with injury characteristics (such as mechanism) and a normal initial radiograph might exclude fracture. Pain on supination against resistance would benefit from external validation.

Ankle injuries are one of the most common presentations in the ED. Although fractures can be ruled out using the Ottawa Ankle Rules, the specificity is low, which means many patients may still receive unnecessary radiographs. Even once fractures are ruled out, assessment of ankle stability is recommended to rule out ruptures, but the anterior drawer test has only moderate sensitivity and low specificity and should be performed only after swelling has receded. Ultrasound could be a reliable, cheap and radiation free alternative to diagnose fractures and ligamentous injuries. The purpose of this systematic review was to investigate the accuracy of ultrasound in diagnosing ankle injuries. ⋯ CRD42020215258.
