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. Rapid Response Systems (RRSs) are important for the detection and early management of inpatient deterioration. As the COVID-19 pandemic spread across the United States (US), hospitals were faced with increased volumes of patients requiring hospitalization and critical care services [1] . The initial and subsequent inpatient surges posed unique challenges for RRS response to inpatient emergencies. In addition to often severe respiratory dysfunction, patients with acute deterioration or in-hospital cardiac arrest (IHCA) pose a risk of virus transmission to members of the Rapid Response Team (RRT). Professional societies IHCA guidelines have recommended adaptations including delayed cardiopulmonary resuscitation (CPR) until personal protective equipment (PPE) is available, early endotracheal intubation, and the use of viral filters during ventilation [2] . In addition to these clinical challenges, the impact of the COVID-19 pandemic on the quality improvement limb of the RRS has not been established. Traditional approaches such as high-fidelity simulation have historically played an important role in the ongoing training of RRS teams [3] , but it is unclear if and how hospitals have adapted these programs during the pandemic. We therefore sought to characterize the alterations made to RRS teams at a broad, representative group of U.S. hospitals resulting from response to the COVID-19 pandemic. We conducted an internet-based, cross-sectional survey that was distributed individually to a sample of RRS leaders, physicians, and resuscitation researchers across the US. Participants were identified as professional contacts of study team members and only one individual was contacted from each hospital to avoid duplication. The survey instrument was developed by the lead author (OJLM) and received input from the entire research team. It was further refined based on pilot testing by a sample of clinicians J o u r n a l P r e -p r o o f similar to the sampling frame but not participating from the study. The survey consisted of 67 questions, including hospital characteristics, RRS structure before and during the COVID-19 pandemic, adaptations made to IHCA management, use of simulation, and use of mechanical CPR devices (Supplemental Figure 1 ). Free text responses concerning RRS adaptations during the COVID-19 pandemic were reviewed by two of the study team (OJLM and BSA). The study was deemed exempt from review by the University of Pennsylvania Institutional Review Board. The survey was sent individually to survey participants from June to August 2020 and a follow-up survey was distributed in December 2020 only to those who completed the first survey. Study data were collected and managed using an internet-based clinical research tool (REDCap, Vanderbilt University, Nashville TN) [4] . Site characteristics were tabulated and summarized using descriptive statistics and presented as number (n) with percentage (%), or median with interquartile range (IQR). The survey was sent to forty-six clinicians from 46 hospitals, 40 of which completed a baseline survey (87%). Nineteen of the forty responders (48%) also completed the second follow-up survey. Among the hospitals represented in the survey (Table 1) , respondents represented hospitals from eighteen US states, primarily in the Northeast (22/40, 55%), the Midwest (7/40, 18%), and Western USA (7/40, 18%): the majority were academic medical centers (33/40, 83%); and 7/40 (18%) were community hospitals. At the time of survey completion, nearly all hospitals surveyed (95%) had at least one COVID-19 patient who experienced IHCA. All sites reported having at least one type of emergency team (RRT, Cardiac Arrest Team, or Emergency Intubation Team) that existed before the COVID-19 pandemic. Most hospitals reported an increase in emergency team resources during the COVID-19 pandemic: Eighteen hospitals (45%) increased staffing of existing teams; 18/40 (45%) added teams; 15/40 (56%) provided additional equipment to their teams; J o u r n a l P r e -p r o o f and 2/40 (5%) extended the hours of existing in-hospital emergency teams. Prior to COVID-19, 23/40 (58%) had mechanical CPR devices available for inpatient use, and this increased to 85% during the COVID-19 pandemic as 11 hospitals purchased mechanical CPR devices specifically for use during the COVID-19 pandemic. Most hospitals made multiple adaptations to their IHCA protocols: 38/40 (95%) employed use of viral filters for ventilation, 32/40 (80%) stopped chest compressions during intubation, and 38/40 (95%) used video laryngoscope when possible. All sites required Personal Protective Equipment (PPE) prior to initiating CPR in COVID-19 patients who had suffered IHCA and 24/40 (60%) required PPE during IHCA even when the patient was COVID-19 negative. Prior to the COVID-19 pandemic, clinical simulation training was used in the majority of surveyed hospitals -35/40 (88%), 31/35 (89%) in simulation labs and 24/35 (69%) with in situ simulations. The number of sites performing simulation training during the COVID-19 pandemic, either in simulation laboratories or in situ decreased to 21/40 (53%). During the pandemic, simulations more commonly focused on intubation (19/21, 90%) and IHCA (18/21, 86%), rather than decompensating patients more generally (10/21, 48%). The most commonly cited reason for the decrease in the use of in-laboratory simulation during the pandemic was concern surrounding virus transmission to simulation participants. PPE consumption and lack of instructor and participant availability were also implicated. Several sites developed alternative approaches to simulation during the pandemic, including reductions in class size, development of educational video resources, and use of augmented and virtual reality simulation. J o u r n a l P r e -p r o o f Nineteen participants (48%) provided free text responses. Themes identified included minimizing the number of people in rooms during events (11/19 responses, 58%), the use of mechanical CPR during IHCA (11/19 responses, 58%), an emphasis on interventions to protect members of the resuscitation team (11/19 responses, 58%), collaboration with other departments to provide patient care (6/19 responses, 32%) ( Table 2) . We have described the adaptations that hospitals have made to emergency teams in the face of the COVID-19, including an increase in resources available to emergency teams and a rapid adoption of American Heart Association IHCA recommendations specific to COVID-19 [2] . Interestingly, our surveyed clinicians reported a drop-off in simulation training, both in the laboratory and in situ environments. The management of deteriorating patients with COVID-19 poses a particular challenge due to the risk of virus transmission to the responding team. Given the large number of hospitalizations seen during surges of COVID-19, the increased resources made available seem to be a logical step to ensure the continued ability to respond to inpatient emergencies. However, the accompanying decrease in simulation suggests a potential area of future concern surrounding team functioning and communication. For the most part, RRSs at responding institutions adapted the guidance of professional societies such as the AHA for management of IHCA including measures to protect the resuscitation team, although we did not determine whether these were standard-of-care prior to the COVID-19 pandemic [2] . It is unclear whether such changes will impact outcomes from IHCA. High-fidelity or in situ simulation provides an ideal opportunity to identify areas for quality improvement during the RRS's response to deteriorating patients [5, 6] . Simulation carries many potential benefits when adapting to such a pandemic, allowing for testing of new protocols and just-in-time learning, but requires J o u r n a l P r e -p r o o f groups of in-person learners with risk of infection, consumes PPE, and places additional workload on already fatigued clinical staff required to participate in and supervise simulation sessions [7] . We found that many hospitals that had previously performed simulation training were no longer using this approach during the pandemic, with a marked reduction in laboratory simulations. The impact of this reduction in simulation during COVID-19 is unclear and is deserving of further study. Two themes that emerged were the adoption of two interventions: active crowd control at events and the use of mechanical CPR devices. Although both were likely implemented to reduce team members exposure during inpatient emergencies, it is possible that these interventions could impact team functioning. Crowd size has frequently been identified as a barrier to effective team functioning and, although it is best studied in out-of-hospital cardiac arrest, mechanical CPR has been associated with improved survival after IHCA [8] [9] [10] [11] . More studies will be required to evaluate the consequences, intended and unintended, on changes made to the structure and function of IHCA and RRT teams during the COVID-19 pandemic. Our study has several limitations that must be considered. First, due to the small sample size of the study and non-random sampling methods, responses may not be representative of protocol modifications implemented by most hospitals in the U.S. Although a large number of states were represented, most of the survey respondents were from academic medical centers that may have very different resources compared to community hospitals. As we did not collect detailed hospital-level information, we were unable to determine whether our sample was representative of the range of hospitals across the country. This is especially pertinent given the wide variation in emergency team structure in the United States [12] . The second round of the survey also had a lower response rate than the first, which may further impact the generalizability of our findings. Additionally, we only captured adaptations that had been made at the time of the initial survey, which took place during the initial wave of COVID-19 in the United States and not subsequent adaptations to team structure or function. The COVID-19 pandemic continues to present challenges to in-hospital emergency teams. Most hospitals in our study increased resources and implemented protocol changes to minimize exposure of the resuscitation team to transmissible virus as recommended by national societies. A particularly notable change was the decrease in simulation training, especially modeling patient decompensation.
