Optimizing emergency care for the aging population is an important future challenge, as the proportion of older patients at the emergency department (ED) rapidly increases. Older patients, particularly those who are frail, have a high risk of adverse outcomes after an ED visit, such as functional decline, institutionalization, and death. The ED can have a key position in identifying frail older patients who benefit most from comprehensive geriatric care [including delirium preventive measures, early evaluation of after-discharge care, and a comprehensive geriatric assessment (CGA)]. ⋯ Therefore, quick and easy-to-use instruments are needed to identify older patients at risk for adverse outcomes. This narrative review outlines the importance and complexity of frailty assessment at the ED. It aligns the available screening instruments, including clinical judgment as frailty assessment, and summarizes arguments for and against frailty assessment at the ED.

Meta Analysis
Use of backboards in cardiopulmonary resuscitation: a systematic review and meta-analysis.
To achieve optimal chest compression depth, victims of cardiac arrest should be placed on a firm surface. Backboards are usually placed between the mattress and the back of a patient in the attempt to increase cardiopulmonary resuscitation (CPR) quality, but their effectiveness remains controversial. A systematic search was performed to include studies on humans and simulation manikins assessing CPR quality with or without backboards. ⋯ Out of 557 records, 16 studies were included in the review and all were performed on manikins. The meta-analysis, performed on 15 articles, showed that the use of backboards during CPR increases chest compression depth by 1.46 mm in manikins. Despite statistically significant, this increase could have a limited clinical impact on CPR, due to the substantial heterogeneity of experimental conditions and the scarcity of other CPR quality indicators.

Meta Analysis
Thiamine combined with vitamin C in sepsis or septic shock: a systematic review and meta-analysis.
Thiamine and vitamin C have been increasingly used in patients with sepsis or septic shock because of their potential for improving metabolism and reducing mortality. ⋯ Despite widespread enthusiasm for thiamine combined with vitamin C for sepsis and septic shock, we only found an association with reduced SOFA score and time of vasopressor use. There was no association with in-hospital mortality.

Meta Analysis
Effect of oxygen supply on mortality in acute ST-elevation myocardial infarction: systematic review and meta-analysis.
Previous studies stated that high oxygen supply in patients with myocardial infarction (MI) was not associated with improved outcomes. However, the particularities of ST-elevation myocardial infarction (STEMI) and the results of a recent trial raised the question if this subgroup of patients benefits from high oxygen supply. This study aims to evaluate the clinical effect of high oxygen supply in patients with STEMI using a systematic review of the available literature. ⋯ Recurrent MI presented a contradictory result, favouring the lower oxygen protocol (RR 1.47; 95% CI, 0.84-2.56; I2 = 0%). The GRADE analysis was very low. High oxygen supply may be associated with a decrease in short-term mortality in STEMI patients, but the pooled data are not robust enough to allow definitive conclusions.

The stress response to acute disease is characterized by activation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathoadrenal system, increased serum cortisol levels, increased percentage of its free fraction and increased nuclear translocation of the glucocorticoid-receptor complex, even though many pathways may be inhibited by poorly understood mechanisms. There is no consensus about the cutoff point of serum cortisol levels for defining adrenal insufficiency. Furthermore, recent data point to the participation of tissue resistance to glucocorticoids in acute systemic inflammatory processes. ⋯ Critical illness-related corticosteroid insufficiency was defined as a dynamic condition characterized by inappropriate cellular activity of corticosteroids for the severity of the disease, manifested by persistently elevated proinflammatory mediators. There is no consensus regarding the diagnostic criteria and treatment indications of this syndrome. Therefore, the benefits of administering corticosteroids to critically ill patients depend on improvements in our knowledge about the possible disruption of its fragile signalling structure in the short and long term.
