Emergency Department-initiated High-flow Nasal Cannula for COVID-19 Respiratory Distress.

INTRODUCTION: Patients with coronavirus disease 2019 (COVID-19) can develop rapidly progressive respiratory failure. Ventilation strategies during the COVID-19 pandemic seek to minimize patient mortality. In this study we examine associations between the availability of emergency department (ED)-initiated high-flow nasal cannula (HFNC) for patients presenting with COVID-19 respiratory distress and outcomes, including rates of endotracheal intubation (ETT), mortality, and hospital length of stay. METHODS: We performed a retrospective, non-concurrent cohort study of patients with COVID-19 respiratory distress presenting to the ED who required HFNC or ETT in the ED or within 24 hours following ED departure. Comparisons were made between patients presenting before and after the introduction of an ED-HFNC protocol. RESULTS: Use of HFNC was associated with a reduced rate of ETT in the ED (46.4% vs 26.3%, P <0.001) and decreased the cumulative proportion of patients who required ETT within 24 hours of ED departure (85.7% vs 32.6%, P <0.001) or during their entire hospitalization (89.3% vs 48.4%, P <0.001). Using HFNC was also associated with a trend toward increased survival to hospital discharge; however, this was not statistically significant (50.0% vs 68.4%, P = 0.115). There was no impact on intensive care unit or hospital length of stay. Demographics, comorbidities, and illness severity were similar in both cohorts. CONCLUSIONS: The institution of an ED-HFNC protocol for patients with COVID-19 respiratory distress was associated with reductions in the rate of ETT. Early initiation of HFNC is a promising strategy for avoiding ETT and improving outcomes in patients with COVID-19.

Outcomes after Falls Continue to Worsen Despite Trauma and Geriatric Care Advancements.

The most common mechanism of traumatic injury is ground-level fall. The objective of this study was to understand how patients sustaining falls and their outcomes have evolved. An institutional trauma database was used to identify adult patients who suffered a fall and were admitted to a Level I trauma center during two distinct time periods: 1998 to 2003 (past) and 2008 to 2013 (current). Data on anticoagulant use and comorbidities was gathered by retrospective chart review of patients treated during 2003 and 2013. Univariable analyses and multivariable regression were used to evaluate demographics and outcomes. A total of 6116 patients were identified, with a 24 per cent increase in number of falls between groups. Current fall patients are older (70 vs 66 years, P < 0.001), more often admitted to intensive care (28 vs 12%, P < 0.001), have longer lengths of stay (5 vs 4 days, P < 0.001), are frequently discharged to skilled nursing facilities (24 vs 8%, P < 0.001), and have higher mortality (5 vs 3%, P = 0.002). The adjusted odds of mortality for patients treated during 2003 and 2013 was associated with age, gender, injury severity score, and Glasgow Coma Scale score. Current fall patients use more health care resources and have worse outcomes, despite advances in trauma and geriatric care.
