A randomised clinical trial of awake prone positioning in COVID-19 suspects with acute hypoxemic respiratory failure.

Background: Awake prone position (APP) has been reported to improve oxygenation in patients with COVID-19 disease and to reduce the requirement for invasive mechanical ventilation for patients requiring support with high flow nasal cannula. There is conflicting data for patients requiring lower-level oxygen support.

Research Question: Does APP reduce escalation of oxygen support in COVID-19 patients requiring supplementary oxygen?The primary outcome was defined as an escalation of oxygen support from simple supplementary oxygen (NP, HM, NRB) NIV (CPAP or BiPAP), HFNC or IMV; from NIV (CPAP or BiPAP) or HFNC IMV by day30.

Clinical implications of serum myoglobin in trauma patients: A retrospective study from a level 1 trauma center.

Background: We aimed to study the clinical implication of high serum myoglobin levels in trauma patients.

Methods: A retrospective analysis was conducted on data from trauma patients who were admitted to a level 1 trauma center between January 2012 and December 2015. A receiver operating characteristic (ROC) curve analysis was performed for the optimum myoglobin cutoff plotted against hospital length of stay of >1 week.

Marginal analysis in assessing factors contributing time to physician in the Emergency Department using operations data.

Standard Emergency Department (ED) operations goals include minimization of the time interval (tMD) between patients' initial ED presentation and initial physician evaluation. This study assessed factors known (or suspected) to influence tMD with a two-step goal. The first step was generation of a multivariate model identifying parameters associated with prolongation of tMD at a single study center.

Health System Response and Adaptation to the Largest Sandstorm in the Middle East.

The State of Qatar experienced a sandstorm on the night of April 1, 2015, lasting approximately 12 hours, with winds of more than 100 km/h and average particulate matter of approximately 10 μm in diameter. The emergency department (ED) of the main tertiary hospital in Qatar managed 62% of the total emergency calls and those of higher triage order. The peak load of patients during the event manifested approximately 6 hours after the onset.
