Although sedation during gastrointestinal endoscopy is widely used in China, the characteristics of sedation use, including regional distribution, personnel composition, equipment used, and drug selection, remain unclear. The present study aimed to provide insights into the current practice and regional distribution of sedation for gastrointestinal endoscopy in China. ⋯ The sedation rate for gastrointestinal endoscopy is much lower in China than in the USA and in Europe. The most commonly used combination of sedatives was propofol plus an opioid (either fentanyl or sufentanil). Emergency support devices, such as difficult airway devices and defibrillators, were not usually available.

Observational Study
Postoperative delirium mediates 180-day mortality in orthopaedic trauma patients.
Frailty has been associated with increased incidence of postoperative delirium and mortality. We hypothesised that postoperative delirium mediates a clinically significant (≥1%) percentage of the effect of frailty on mortality in older orthopaedic trauma patients. ⋯ Frailty is associated with increased postoperative mortality, and delirium might mediate a clinically significant, but small percentage of this effect. Studies should assess whether, in patients with frailty, attempts to mitigate delirium might decrease postoperative mortality.

The COVID-19 pandemic has impacted healthcare in various vulnerable patient subpopulations. However, data are lacking on the impact of COVID-19 on hip fractures, seen mainly in older patients. Using national claims data, we aimed to describe the epidemiology during the first COVID-19 wave in the USA. ⋯ The COVID-19 pandemic significantly impacted not only volume of hip fractures, but also patterns in care and outcomes. These results may inform policymakers in future outbreaks and how this may affect vulnerable patient populations, such as those experiencing a hip fracture.
