Scarce literature exists on comfort of clinicians (defined as physicians, nurses & advanced practice providers-APP's) in these new roles and their perceived understanding of new algorithms. METHODS: Routine CPA care in our ED was modified during the COVID-19 pandemic. This involved clinicians in shared leadership roles alongside COVID-19 specific changes to CPA algorithms. The new protocol was operationalized through a two-step educational intervention involving didactic education and in-situ simulations. Univariate analyses using student's t-test assessed effectiveness of this educational intervention with clinician comfort as team leaders and perceived knowledge as primary outcomes on a scale of 1 (strongly disagree) to 5 (strongly agree). Subgroup analysis across physicians (attending & resident), nurses & APP's were also undertaken with an alpha of 0.05, and p values <0.05 were considered statistically significant. Secondary outcomes of task saturation, procedural safety and error prevention were also analyzed. RESULTS: Across 83 of 95 total participants, our primary outcome of clinician comfort in the team leader role improved from a mean value of 3.41 (SD: 1.23) pre-intervention to 4.11 (SD: 0.88) with a p-value <0.001 post intervention. Similar and statistically significant findings in clinician comfort were noted across all subgroups except attending physicians and APP's. Perceived knowledge increased from a mean value of 3.54 (SD: 1.06) pre-intervention to a mean value of 4.24 (SD: 0.67) with a p-value <0.001 post intervention. Similar and statistically significant findings in perceived knowledge were noted across all subgroups except APP's. Responses were registered in either the strongly agree or agree category with regards to task saturation (89%), procedural safety (93%) and error prevention (71%) across all clinicians post intervention. CONCLUSION: Our pilot investigation of the effectiveness of an educational intervention of a novel CPA protocol in the ED during the COVID-19 pandemic reached statistical significance with regards to clinician comfort in shared leadership roles and perceived knowledge. These findings suggest that the protocol is rapidly teachable, usable and can be efficiently disseminated across ED clinicians of varying experience, especially in pandemic settings. Further work regarding effectiveness of this new protocol in real life cardiac arrest scenarios is warranted. Many resuscitation protocols across emergency departments (ED) have undergone modifications during the coronavirus disease (COVID-19) pandemic. Historically, the resuscitation of patients in cardio-pulmonary arrest (CPA) in the ED has been in large, multidisciplinary teams. 1, 2 While prior iterations of the advanced cardiac life support (ACLS) guidelines have advocated for these large teams [1] [2] [3] [4] [5] , more recent guidance has recommended against such team configurations owing to significant risk of healthcare worker (HCW) exposure during a pandemic. [6] [7] [8] [9] [10] As part of our institution"s response in the ED to CPA care during the COVID-19 pandemic, a combined nursing and physician-based leadership model of cardiac arrest care was devised and instituted. The primary intention behind this change was to limit HCW exposure during a resuscitation where significant Aerosol Generating Procedures (AGP"s) would occur. 6 A secondary intention was to use this unique opportunity to share the responsibility of code team leader with nursing personnel as physician shortages were anticipated. In correspondence with other academic ED"s, this practice has sometimes been referred to as nurse led codes. To the best of our knowledge, there is scant to no formal literature on outcomes associated with nurse led codes in the ED setting and certainly not during pandemic settings. [11] [12] [13] [14] [15] [16] This study will present the findings of an educational intervention on perceived knowledge and clinician comfort of a novel CPA protocol with joint physician and nursing leadership in an academic ED setting during the COVID-19 pandemic. Dual Emergency Medicine and Critical Care Medicine boarded physicians and core nursing representatives in our department designed a protocol specifically for the care of patients with CPA in the ED during the COVID-19 pandemic. Ideal team member composition and specific roles in this protocol are shown in Appendix A. Exact team composition for this study consisted of five essential HCW"s consisting of: one MD physician, two registered nurses (RN"s), 1 licensed practical nurse (LPN), and one respiratory therapist (RT). The major difference between this protocol and prior protocols was a shared and interchangeable role of code team leader between nursing staff and physicians. The protocol was designed to ideally have a physician leader in charge of the physician and RT personnel and a nursing leader in charge of the nursing and licensed nursing assistant (LNA) personnel. In specific, physicianscontrolled processes such as airway management, execution of procedures and decisions around termination of resuscitative efforts. Similarly, nursing personnel were in charge of the algorithmic portions of the specific ACLS algorithm being carried out. Specific tasks included medication administration, maintenance of CPR quality, timely defibrillation and strict compliance with personal protective equipment (PPE) requirements. Additionally, the design restricted the total number of HCW"s and equipment taken within the room. After this protocol was designed, we undertook a two-step intervention for the dissemination and familiarization of this new protocol with all providers in the ED. The first step involved didactic training which included educational sessions at faculty meetings, didactic resident lectures, daily nursing huddles, emailing staff list serves and the placement of laminated cards with this protocol (Appendix A) in each room in our ED. The second step involved an insitu simulation of this protocol with the entirety of the proposed team in the ED twice daily for J o u r n a l P r e -p r o o f approximately two weeks. Specific details of the in-situ simulation are described in the Appendix B. We coined the term Tandem Codes to reflect the joint physician and nursing code team leadership in this new model. Approximately, three weeks after the simulations ended, an anonymous ten question survey (Appendix C) was sent to the entire staff in the ED and results were analyzed. These responses were asked of all respondents on a subjective scale divided in the sub-categories of: Strongly Agree, Agree, Neither Agree/Disagree, Disagree or Strongly Disagree. This process of protocol design, educational dissemination and timing of survey is summarized in Appendix D. Our null hypothesis was that prior physician led code team models would be no different to tandem physician and nursing led code teams with regards to confidence in leading the team and perceived knowledge. Our primary outcomes were: clinician self-rating of confidence in leading the ED based CPA teams and perceived knowledge of the new model (cumulative across all participants). Secondary outcomes were: assessment of confidence as team leaders and perceived knowledge of the new model across clinical subgroups (nursing, attending physicians, resident physicians and APP"s), provider self-rating of task saturation, procedural safety and error prevention during CPA in this novel protocol as compared to the prior practices. Throughout this manuscript, the term "clinicians" refers to the combined group of physicians, nurses and APP"s. APP"s in our study are a combined set of advanced practice nurse practitioners and physician assistants. All statistical analyses were done in a blinded fashion by the authors. Authors only knew the designation of respondents within the ED (attending, resident, nurse, APP) and their years of experience. The authors did not have any relevant and reportable conflicts of interest and this study was deemed exempt by the institutional review board as no patient health information was J o u r n a l P r e -p r o o f involved. We conducted our initial data analysis via qualitative bar graphs for both the primary and secondary outcomes. Subsequently univariate analyses were done by converting subjective survey responses to a numerical scale 1-5, where a score of 1 corresponded to Strongly Disagree, score of 2 for Disagree, score of 3 for Neither Agree or Disagree, a score of 4 for Agree, and a score of 5 for Strongly Agree. Descriptive statistics were conveyed as mean ± standard deviations. To assess for differences in pre-and post-test responses, with a p-value derived from a student's t-test. P-values <0.05 were considered statistically significant. Statistical analysis was performed using Stata/IC (College Station, TX: StatCorp LLC). The following are abbreviations: ED-emergency department, CPA-cardio-pulmonary arrest, ACLS-advanced cardiac life support, HCW-healthcare worker, AGP"s-aerosol generating procedures, LNA-licensed nursing assistant. PPE-personal protective equipment, RN-registered nurses, APP-advanced practice providers, and POCUS-point of care ultrasound. After didactic education of the entire ED staff, we had 95 respondents to our final survey ( Table 1) . As shown in Appendix D, 12 participants were excluded from final analysis, as these respondents did not partake in the simulation portion of our two-step intervention. Of the final 83 clinicians analyzed, there were 34 physicians, 44 nurses and 5 APP"s of varying experience and seniority. This translates to an overall response rate of 89% amongst attending physicians, 61% amongst resident physicians, 100% amongst APP"s and 88% amongst nursing personnel. Within the physicians, there were 23 attending physicians and 11 resident physicians. Years of experience amongst practitioners were analyzed in two main categories: 0-10 years and over 10 J o u r n a l P r e -p r o o f years. Cumulative attending and resident physician years of experience revealed a value of 17/34 for 0-10 years and n=17/34 for over 10 years of experience. Amongst attending physicians only there were 6/23 (26%) who had 0-10 years of experience and 17/23 (74%) who had over 10 years of experience. Across nursing personnel, there were 31/44 (70%) who had 0-10 years of experience and 13/44 (30%) who had over 10 years of experience. All resident physicians had less than three years of cumulative experience. All APP"s had less than 10 years of experience. The two-step intervention seems to have been preferentially been taken by senior attending physicians and relatively junior nursing personnel in terms of years of experience. Across all participants, clinician comfort as team leader of a tandem-led code increased after the two-step intervention. As shown in Fig. 1 , the intervention seemed to simultaneously increase clinician comfort and reciprocally decrease clinician discomfort for the role of team leader across all clinician groups. On average, clinician comfort level before and after the intervention amongst all participants was 3.41 (1.23) and 4.11 (0.88), respectively with a p value <0.001 ( Table 2 ). The positive increase reflects a statistically significant transition from the neutral neither agree or disagree category towards the agree category for perceived clinician comfort amongst all surveyed participants. Clinician subset analysis in Table 2 (Table 3 ). The positive increase reflects a statistically significant transition from the neutral neither agree or disagree category towards the agree category for core knowledge amongst all surveyed participants. As seen in Table 3 , all subsets of clinicians also displayed this statistically significant and positive transition in their perceived knowledge of the new protocol. The only exception was the group of APP"s, where there was a positive deflection in its mean value but did not reach statistical significance. In general, tandem-led codes were reported to reduce the amount of task saturation for the physician (Figure 3 ). Across all participants, 40% Strongly Agree, 48% Agree, 10% Neither Agree or Disagree, 2 % Disagree and 0% Strongly Disagree (Table A. sustained across all subsets of clinicians except nursing personnel. Specifically and in contrast to their physician and APP counterparts, nursing personnel had the highest proportions that either responded in the Disagree or Neither Agree or Disagree category. As shown in Figure 3 , tandem-led codes were reported to allow the physician more time to focus on procedures such as airway management, placement of intra-vascular catheters and performance of point of care ultrasound (POCUS). Across all participants, 51% Strongly Agree, 42% Agree, 7% Neither Agree nor Disagree, 0 % Disagree and 0% Strongly Disagree (Table A. 5) . No notable differences were found in the overall responses from each individual subgroup. As shown in Figure 3 , tandem-led codes were self-reported to be helpful in reduction of all error subtypes during a CPA. Across all participants, 31% Strongly Agree, 40% Agree, 29% Neither Agree nor Disagree, 0 % Disagree and 0% Strongly Disagree (Table A. The exact role of nursing personnel alongside physicians as team leaders during a CPA resuscitation is a matter of great clinical equipoise and debate. [11] [12] [13] [14] [15] Conventionally, physicians or APP"s have held the roles of team leaders. More recently, varying clinical models have led to graduated increases in nursing responsibilities during CPA"s. 16 In specific, these models have nursing personnel be completely in-charge of the algorithmic portions of ACLS: CPR quality, timely medication administration and defibrillation. Our study incorporated these aforementioned principles but also advocated for joint physician-nursing leadership in the team via a two-step educational intervention as part of our ED based response to cardiac arrest care during the COVID-19 pandemic. To the best of our knowledge, our study is the first to study the ED based feasibility and efficacy of teaching a tandem physician and nursing leadership model for cardiac arrest care in pandemic settings at an academic medical center. Reduction in task saturation & CPA protocol deviations and increase in safe execution of procedures were also reported by all participants with this new protocol. This is of particular importance in the pandemic setting where routine CPA care is performed with the added challenges of airborne precautions and increased risk to HCW"s secondary to numerous AGP"s inherent to cardiac arrest care. 6, 9 Interestingly, the nursing subgroup felt most indifferent with regards to this new protocol being helpful in reducing task saturations and errors. This may be explained by the comparative lack of nursing experience with procedural and managerial tasks, as well as their associated errors that were conventionally the prerogative of physicians. However, it is reassuring that all our clinicians universally felt that they could effectively delegate core tasks, safely perform AGP"s and contribute to an overall reduction in errors. Future work done in real life scenarios should also look to measure these metrics. Within the constructs of a pandemic, it would be crucial to measure unintentional transmission of infection to HCW"s and classify errors within the subtypes of errors of commission and/or omission in a cardiac arrest framework. This was a single center study with relatively low power that is subject to recall bias. However, this is the largest analysis to date on the topic and the primary intention was to assess clinician comfort and safe, effective dissemination of core knowledge of a new protocol. Due to the high participation and response rate in all clinician subgroups, we believe that the two-step intervention had great penetration within our group. Within our center, a higher power would likely be unachievable as some resident physicians (group with lowest participation) were on J o u r n a l P r e -p r o o f clinical rotations outside the ED and/or in quarantine at the time. Given the state of clinical urgency during which the study was conducted, pre-intervention assessments of participants" feelings, such as perceived knowledge and comfort, were not pursued. Further analysis of these perceptions may provide insight into the significance of the intervention"s downstream clinical benefits, since participants may not accurately recall their perceptions prior to the intervention. Additionally, this is a simulation-based study and generalizability to real life CPA"s is limited. Yet, this pilot investigation was necessary to assess safety and feasibility of this new protocol, especially in a pandemic. A two-step educational intervention that includes didactic education and in-situ simulation is a practical and safe way to disseminate a novel cardiac arrest care protocol in an ED setting during a pandemic. In specific, a tandem physician and nursing led cardiac arrest protocol was teachable and deployable within a very short time period across all clinician subtypes. All participants reported increased clinician comfort in the team leader role and perceived knowledge with this intervention across qualitative and quantitative analyses. Tandem Codes allowed assessments within the domains of task saturation, procedural safety and error prevention in a simulation environment. However, the intervention will need to be further validated in real life cardiac arrest scenarios. Assessments of this protocol in real life CPA care during the COVID-19 pandemic are ongoing and additional data will be analyzed to provide post-clinical implementation assessments, in order to further confirm statistically significant findings from our study. Future studies could assess the clinically translatable benefits of this two-step intervention by measuring the ability of clinicians to delegate core tasks, mitigation of HCW"s exposure from AGP"s, and reduction of clinical errors during CPA"s.
