Background: Management of patients with acute deterioration from novel coronavirus disease of 2019 (COVID-19) has posed a particular challenge for rapid response systems (RRSs) due to increased hospital strain and direct risk of infection to RRS team members. Objective: We sought to characterize RRS structure and protocols adaptions during the COVID-19 pandemic. Design, setting, and participants: Internet-based cross-sectional survey of RRS leaders, physicians, and researchers across the United States. Results: Clinicians from 46 hospitals were surveyed, 40 completed a baseline survey (87%), and 19 also completed a follow-up qualitative survey. Most reported an increase in emergency team resources during the COVID-19 pandemic. The number of sites performing simulation training sessions decreased from 88% before COVID-19 to 53% during the pandemic. Conclusions: Most RRSs reported pandemic-related adjustments, most commonly through increasing resources and implementation of protocol changes. There was a reduction in the number of sites that performed simulation training.

Aims: To define outcomes of patients with COVID-19 compared to patients without COVID-19 suffering in-hospital cardiac arrest (IHCA). Materials and methods: We performed a single-center retrospective study of IHCA cases. Patients with COVID-19 were compared to consecutive patients without COVID-19 from the prior year. Return of spontaneous circulation (ROSC), 30-day survival, and cerebral performance category (CPC) at 30-days were assessed. Results: Fifty-five patients with COVID-19 suffering IHCA were identified and compared to 55 consecutive IHCA patients in 2019. The COVID-19 cohort was more likely to require vasoactive agents (67.3% v 32.7%, p = 0.001), invasive mechanical ventilation (76.4% v 23.6%, p
