Effect of the COVID-19 pandemic on cardiac arrest resuscitation practices and outcomes in non-COVID-19 patients.

The effect of changes to cardiopulmonary resuscitation (CPR) procedures in response to Coronavirus disease 2019 (COVID-19) on in-hospital cardiac arrest (IHCA) management and outcomes are unreported. In this multicenter retrospective study, we showed that median time to arrival of resuscitation team has increased and proportion of patients receiving first-responder CPR has lowered during this pandemic. IHCA during the pandemic was independently associated with lower return of spontaneous circulation OR 0.63 (95% CI 0.43-0.91), despite adjustment for lowered patient comorbidity and increased time to resuscitation team arrival. Changes to resuscitation practice in this pandemic had effects on IHCA outcomes, even in patients without COVID-19.

Early intubation versus late intubation for COVID-19 patients: An in situ simulation identifying factors affecting performance and infection control in airway management.

COVID-19 poses an infectious risk to healthcare workers especially during airway management. We compared the impact of early versus late intubation on infection control and performance in a randomised in situ simulation, using fluorescent powder as a surrogate for contamination. Twenty anaesthetists and intensivists intubated a simulated patient with COVID-19. The primary outcome was the degree of contamination. The secondary outcomes included the use of bag-valve-mask ventilation, the incidence of manikin cough, intubation time, first attempt success and heart rate variability as a measure of stress. The contamination score was significantly increased in the late intubation group, mean (standard deviation, SD) 17.20 (6.17), 95% confidence intervals (CI) 12.80 to 21.62 versus the early intubation group, mean (SD) 9.90 (5.13), 95% CI 6.23 to 13.57, P = 0.005. The contamination score was increased after simulated cough occurrence (mean (SD) 18.0 (5.09) versus 5.50 (2.10) in those without cough; P<0.001), and when first attempt laryngoscopy failed (mean (SD) of 17.1 (6.41) versus 11.6 (6.20) P = 0.038). The incidence of bag-mask ventilation was higher in the late intubation group (80% versus 30%; P=0.035). There was no significant difference in intubation time, incidence of failed first attempt laryngoscopy or heart rate variability between the two groups. Late intubation in patients with COVID-19 may be associated with greater laryngoscopist contamination and potential aerosol-generating events compared with early intubation. There was no difference in performance measured by intubation time and incidence of first attempt success. Late intubation, especially when resources are limited, may be a valid approach. However, strict infection control and appropriate personal protective equipment usage is recommended in such cases.

Adult ICU Triage During the Coronavirus Disease 2019 Pandemic: Who Will Live and Who Will Die? Recommendations to Improve Survival.

OBJECTIVES: Coronavirus disease 2019 patients are currently overwhelming the world's healthcare systems. This article provides practical guidance to front-line physicians forced to make critical rationing decisions. DATA SOURCES: PubMed and Medline search for scientific literature, reviews, and guidance documents related to epidemic ICU triage including from professional bodies. STUDY SELECTION: Clinical studies, reviews, and guidelines were selected and reviewed by all authors and discussed by internet conference and email. DATA EXTRACTION: References and data were based on relevance and author consensus. DATA SYNTHESIS: We review key challenges of resource-driven triage and data from affected ICUs. We recommend that once available resources are maximally extended, triage is justified utilizing a strategy that provides the greatest good for the greatest number of patients. A triage algorithm based on clinical estimations of the incremental survival benefit (saving the most life-years) provided by ICU care is proposed. "First come, first served" is used to choose between individuals with equal priorities and benefits. The algorithm provides practical guidance, is easy to follow, rapidly implementable and flexible. It has four prioritization categories: performance score, ASA score, number of organ failures, and predicted survival. Individual units can readily adapt the algorithm to meet local requirements for the evolving pandemic. Although the algorithm improves consistency and provides practical and psychologic support to those performing triage, the final decision remains a clinical one. Depending on country and operational circumstances, triage decisions may be made by a triage team or individual doctors. However, an experienced critical care specialist physician should be ultimately responsible for the triage decision. Cautious discharge criteria are proposed acknowledging the difficulties to facilitate the admission of queuing patients. CONCLUSIONS: Individual institutions may use this guidance to develop prospective protocols that assist the implementation of triage decisions to ensure fairness, enhance consistency, and decrease provider moral distress.
