Introduction: Between 1980 and 2008, survival rates following an out-of-hospital cardiac arrest (OHCA) have remained unchanged, averaging 7.6%. Despite the use of new and emerging technologies, new medications, and automated external defibrillators, survival remains low. Recently, a new focus in cardiopulmonary resuscitation (CPR) has shown dramatic improvements in survival post OHCA. This new model, called pit-crew CPR, focuses on minimizing interruptions in chest compressions and has each team member playing a specific role in the resuscitation, akin to the pit-crew of a car race. Certain districts in the United States and Canada have adopted the pit-crew, or a similar, high quality, maximum time-on-chest CPR model, with much success. We aim to determine whether the pit-crew model of CPR improves survival following OHCA in Saskatoon, SK. Methods: In Saskatoon, EMS and Fire crews respond to OHCAs and have been exclusively using the pit-crew model of CPR since Jan 1st, 2015. This study is a before and after retrospective chart analysis, comparing two groups - pre and post implementation of the pit-crew CPR model. The primary outcome is survival to hospital discharge post OHCA. Secondary outcomes include survival to admission and any return of spontaneous circulation (as per the Utstein definition). The inclusion criteria are patients >18 years old with a witnessed OHCA of presumed cardiac origin who receive CPR by EMS/Fire within the Saskatoon Ambulance service (MD Ambulance) catchment area. Patients were excluded if the OHCA was unwitnessed, or if there was a presumed non-cardiac cause for the arrest, e.g. trauma. Results: In the pre-pit-crew model cohort, between Jan 1st, 2011 and Sept 31st, 2014, 455 OHCAs were analyzed. In this cohort 10.5% survived to discharge, 31.9% survived to admission and ROSC was achieved in 39% of cases. The percentage of patients with initial rhythms of VF/VT, asystole or PEA were 28.5% (26%), 41.5% (1%) and 23.6% (10%) respectively, with survival to discharge shown in parentheses. The post-pit-crew cohort is still in the data collection phase. Conclusion: Our pre-pit crew cohort data has been collected and analyzed. With ongoing data acquisition for the post-pit crew cohort, we hope to have the full data set complete by the end of 2018. It will be at that time when we are able to determine whether the pit-crew model of CPR improves survival to discharge following OHCA in Saskatoon.

Introduction Long pauses without chest compressions (CC) have been identified in CPR provided by EMS professionals for out-of-hospital cardiac arrest (OOHCA). The 2005 AHA ECC CPR guidelines emphasize CC. The 2005 AHA Basic Life Support (BLS) for Healthcare Professionals (HCP) course introduced a training method with more CPR skills practice during the DVD based course. The purpose of this before/after study was to determine whether CC rates increased after introduction of the 2005 course. Methods This urban EMS system has 400 cardiac etiology OOHCA events annually. A convenience sample of 49 continuous electronic ECG recordings of VF patients was analyzed with the impedance channel of the LIFEPAK 12 (Physio-Control, Redmond WA) and proprietary software. A trained researcher verified the automated analysis. Each CC during the resuscitation attempt and pauses in CC before and after the first defibrillation shock were noted. The time of return of spontaneous circulation (ROSC) was determined by medical record review and onset of regular electrical activity without CC. Medical records were reviewed for outcome to hospital discharge. The EMS patient care protocol for VF was changed on July 1, 2006 to comply with the 2005 AHA ECC guidelines. Cases were grouped by the OOHCA date: 9/2004 to 12/31/2006 (pre) and 7/1/2006 to 4/21/2007 (post). EMS personnel began taking the 2005 BLS for HCP course during spring 2006. Monthly courses over 3 years will recertify 1500 personnel. Results 29 cases were analyzed from the pre group and 20 from the post group. Compressions per minute increased from a mean (±SD) of 47 ± 16 pre to 75 ± 33 post (P < 0.01). The mean count of shocks given per victim decreased from 4.5 ± 4.0 pre to 2.8 ± 1.8 post (P < 0.04). The CC pause before the first shock was unchanged (23.6 ± 18.4 seconds to 22.1 ± 17.9). but the CC pause following that shock decreased significantly from 48.7 ± 63.2 to 11.8 ± 22.5 (p=0.008). Rates of ROSC (55% pre, 50% post) and survival to discharge (15% pre, 13% post) were similar. Conclusion Following introduction of the 2005 BLS for HCP course and the EMS protocol change, the quality of CPR delivered to victims of OOHCA improved significantly compared with pre-2006 CPR. The sample size was too small to detect differences in survival rates.

Hospital Cardiac Arrest

Background and Objectives: In-hospital cardiac arrest can be challenging. The frequency of events outside of critical care units is typically low which makes it a stressful event for staff. According to the HEROIC study, there were 209,000 in-hospital cardiac arrests in the United States in 2016. Only 24.9% survived. Get With the Guidelines-Resuscitation is a quality improvement tool for hospitals to measure and evaluate their in-house codes and resuscitation rates. It may be assumed that survival rates are better at larger hospitals. The objective of this study was to examine the association between in-hospital cardiac arrest rates based on the bed size of a hospital. Methods: By using number of beds as a comparison and data from Get With the Guidelines-Resuscitation we sampled 46 hospitals in the eleven-state AHA Midwest Affiliate, (IL, IN, IA, KS, MI, MN, MO, NE, ND, SD, WI), comparing survival to discharge from cardiac arrest, with and without shockable rhythms from January 1, 2013-December 31, 2016. All patients are included in a risk adjusted formula that resides within Get With the Guidelines-Resuscitation. Results: In our comparison, we included hospitals with licensed and/or staffed beds of <100, 100-199, 200-299, 300-399 and 400 or more beds. Our data showed that higher sustained return of spontaneous circulation rates with survival to discharge are not dictated by the size of a hospital. In fact, in all 4 years shown, successful resuscitation rates were higher at hospitals with fewer beds verses larger facilities. Conclusions: Survival to discharge from in-hospital cardiac arrest is not dependent on hospital bed size. It is important that hospitals collect and analyze data regarding in-hospital cardiac arrests to improve survival rates beyond the 24.9% identified in the HEROIC study. A further examination looking at discharge destinations with CPC scores should be considered for a future study.

Abstract Backgroun:This study proposed an algorithm to improve resuscitation outcomes in the emergency department (ED) for patients with traumatic out-of-hospital cardiac arrest (TOHCA). We also performed a retrospective chart review of patient outcomes before and after implementing the algorithm and sought to define factors that might influence patient outcomes.Methods: In September 2018, we implemented an algorithm for patients with TOHCA. This algorithm rapidly identifies possible causes of TOHCA and recommends appropriate interventions. We retrospectively reviewed the outcomes of all patients with TOHCA during a 5-year period and compared the results before and after the implementation of the algorithm.Results:After this algorithm was implemented, the use of the ED interventions of blood transfusion, placement of a large-bore central venous catheter, and thoracostomy increased significantly. Return of spontaneous circulation (ROSC), hospital admission, and survival rates also increased (before vs. after: ROSC: 23.6% vs. 41.5%, P = 0.035; hospital admission: 18.2% vs. 24.6%, P = 0.394; survival: 0.0% vs. 4.6%, P = 0.107). Admitted patients exhibited a higher end-tidal CO2 level than nonadmitted patients [admitted vs. nonadmitted: 41.5 (33.3–52.0) vs. 12.0 (7.5–18.8), P = 0.001].Conclusion:Our algorithm prioritizes the three major treatable causes of TOHCA: impedance of venous return, hypovolemia, and hypoxia. We found that ROSC, hospital admission, and survival rates increased with the increasing implementation of the ED interventions recommended by the algorithm.

Introduction: The interactions of various variables on out-of-hospital cardiac arrest (OHCA) in the young (1-35 years old) outcomes are complex. Network models have emerged as a way to abstract complex systems and gain insights into relational patterns among observed variables. Hypothesis: Network analysis helps provide qualitative and quantitative insights into how various variables interact with each other and affect outcomes in OHCA in the young. Methods: A mixed graphical network analysis was performed using variables collected by CARES. The network allows the visualization and quantification of each unique interaction between two variables that cannot be explained away by other variables in the data set. The strength of the underlying interaction is proportional to the thickness of the connections (edges) between the variables (nodes). We used the mgm package in R. Results: Figure 1 shows the network of the OHCA in the young cases in Chicago from 2013 to 2017. There are apparent clusters. Sustained return of spontaneous circulation and hypothermia are strongly correlated with survival and neurological outcomes. This cluster is in turn connected to the rest of the network by survival to emergency room. The interaction between any two variables can also be quantified. For example, American Indians cases occur more often in disadvantaged locations when compared to Whites (OR 4.5). The network also predicts how much one node can be explained by adjacent nodes. Only 20% of survival to emergency room is explained by its adjacent nodes. The remaining 80% is attributed to variables not represented in this network. This suggests that interventions to improve this node is difficult unless further data is available. Conclusion: Network analysis provides both a qualitative and quantitative evaluation of the complex system governing OHCA in the young. The networks predictive capability could help in identifying the most effective interventions to improve outcomes.

Introduction: Out-of-hospital cardiac arrest (OOHCA) victims are increasing, but emergency medical service system (EMSS) is not ready for them in Korea. A previous randomized, controlled clinical trial has suggested that vasopressin followed epinephrine was superior to epinephrine in patients with asystole. According to the Korean national registry of OOHCA, patients with asystole were more than two thirds of them. In Korean EMSS, no drugs are permitted to administer in the prehospital phase by law. Thereafter epinephrine or vasopressin cannot be administered until patients are transported to emergency departments (EDs). This study was to evaluate whether the combined administration of vasopressin and epinephrine in ED for OOHCA patients would increase the return of spontaneous circulation (ROSC) and survival discharge. Methods: From October 2007 to May 2008, we changed the CPR protocol in adult, nontraumatic OOHCA that 40 U of vasopressin was administered as soon as possible after the first dose of epinephrine (the after group). Cardiac arrest data were collected using the Utstein template. Data from January to September 2007, when vasopressin has not been used, were also collected for comparative analysis (the before group). These two groups were compared in terms of ROSC, and survival discharge Results: There were 45 and 50 patients in the before and after groups, respectively. There was no significant differences in the initial ECG rhythm of asystole (67% vs 78%), witnessed arrest (73% vs 72%), bystander CPR (16% vs 10%), time from collapse to BLS time (6 min vs 8.5 min), and time from collapse to study drugs (23 min vs 26.5 min). The rate of sustained ROSC was similar between the before and after groups (53% vs 48%, P=0.604) as was the survival discharge (27% vs 14%, P=0.123). Conclusions: Vasopressin with administerd with epinephrine does not increase the rate of ROSC nor the survival discharge.

Introduction: Agonal respiration has been shown to be commonly associated with witnessed events, ventricular fibrillation, and increased survival during out-of-hospital cardiac arrest. There is little information on incidence of gasping for in-hospital cardiac arrest (IHCA). Our “Rapid Response Team” (RRT) missions were monitored between December 2010 and March 2015, and the prevalence of gasping and survival data for IHCA were investigated. Methods: A standardized extended in-hospital Utstein data set of all RRT-interventions occurring at the University Hospital Basel, Switzerland, from December 13, 2010 until March 31, 2015 was consecutively collected and recorded in Microsoft Excel (Microsoft Corp., USA). Data were analyzed using IBM SPSS Statistics 22.0 (IBM Corp., USA), and are presented as descriptive statistics. Results: The RRT was activated for 636 patients, with 459 having a life-threatening status (72%; 33 missing). 270 patients (59%) suffered IHCA. Ventricular fibrillation or pulseless ventricular tachycardia occurred in 42 patients (16% of CA) and were associated with improved return of spontaneous circulation (ROSC) (36 (97%) vs. 143 (67%; p<0.001)), hospital discharge (25 (68%) vs. 48 (23%; p<0.001)), and discharge with good neurological outcome (Cerebral Performance Categories of 1 or 2 (CPC) (21 (55%) vs. 41 (19%; p<0.001)). Gasping was seen in 128 patients (57% of CA; 46 missing) and was associated with an overall improved ROSC (99 (78%) vs. 55 (59%; p=0.003)). In CAs occurring on the ward (154, 57% of all CAs), gasping was associated with a higher proportion of shockable rhythms (11 (16%) vs. 2 (3%; p=0.019)), improved ROSC (62 (90%) vs. 34 (55%; p<0.001)), and hospital discharge (21 (32%) vs. 7 (11%; p=0.006)). Gasping was not associated with neurological outcome. Conclusions: Gasping was frequently observed accompanying IHCA. The faster in-hospital patient access is probably the reason for the higher prevalence compared to the prehospital setting. For CA on the ward without continuous monitoring, gasping correlates with increased shockable rhythms, ROSC, and hospital discharge.

Introduction: Survival rates with favorable neurologic function after out-of-hospital cardiac arrest (OHCA) have remained low for decades. Hypothesis: Use of therapies focused on better perfusion during CPR using mechanical adjuncts and protective post-resuscitation care would improve survival and neurologic outcomes after OHCA compared to conventional CPR and care. Methods: OHCA outcomes in Alameda County, CA, USA, population 1.5 million, from December 2009-2011 when there was incomplete availability and use of impedance threshold device [ITD], mechanical CPR [MCPR], and hospital therapeutic hypothermia [HTH], were compared to 2012 when all were available and more widely used. Return of Spontaneous Circulation (ROSC), survival and Cerebral Performance Category (CPC) scores were compared using univariate and multivariable analyses. Results: Of the 3008 non-traumatic OHCAs who received CPR during the study period, >95% of survival outcome data were available. From 2009-11 to 2012, there was an increase in ROSC from 28.6% to 34.1% (p=0.002; OR=1.28; CI=1.09, 1.51) and a non-significant increase in hospital discharge from 10.5% to 12.3% (p=0.14; OR=1.17; CI=0.92, 1.49). There was, however, an 80% increase in survival with favorable neurological function between the two periods, as determined by CPC≤2, from 4.4% to 7.9% (p<0.001; unadjusted OR=1.85; CI=1.35, 2.54). After adjusting for witnessed arrest, bystander CPR, initial rhythm (VT/VF vs. others), placement of an advanced airway, EMS response time, and age, the adjusted OR was 1.60 (1.11, 2.31; p=0.012). Using a stepwise regression model, the most important independent positive predictors of CPC≤2 were 2012 (p=0.019), witnessed (p<0.001), initial rhythm VT/VF (p<0.001), and advanced airway (inverse association p<0.001). Additional analyses of the three therapies, separately and in combination, demonstrated that for all patients admitted to the hospital, ITD use with HTH had the most impact on survival to discharge with CPC≤2 of 24%. Conclusions: Therapies (ITD, MCPR, HTH) developed to enhance circulation during CPR and cerebral recovery after ROSC, significantly improved survival with favorable neurological function by 80% following OHCA.

Abstract Background Incidence of in-hospital cardiac arrest is reported to be 0.8 to 4.6 per 1,000 patient admissions. Patient survival to hospital discharge with favourable functional and neurological status is around 21–30%. The Bern University Hospital is a tertiary medical centre in Switzerland with a cardiac arrest team that is available 24 h per day, 7 days per week. Due to lack of central documentation of cardiac arrest team interventions, the incidence, outcomes and survival rates of cardiac arrests in the hospital are unknown. Our aim was to record all cardiac arrest team interventions over 1 year, and to analyse the outcome and survival rates of adult patients after in-hospital cardiac arrests. Methods We conducted a prospective single-centre observational study that recorded all adult in-hospital cardiac arrest team interventions over 1 year, using an Utstein-style case report form. The primary outcome was 30-day survival after in-hospital cardiac arrest. Secondary outcomes were return of spontaneous circulation, neurological status (after return of spontaneous circulation, after 24 h, after 30 days, after 1 and 5 years), according to the Glasgow Outcomes Scale, and functional status at 30 days and 1 year, according to the Short-form-12 Health Survey. Results The cardiac arrest team had 146 interventions over the study year, which included 60 non-life-threatening alarms (41.1%). The remaining 86 (58.9%) acute life-threatening situations included 68 (79.1%) as patients with cardiac arrest. The mean age of these cardiac arrest patients was 68 ± 13 years, with a male predominance (51/68; 75.0%). Return of spontaneous circulation was recorded in 49 patients (72.1%). Over one-third of the cardiac arrest patients (27/68) were alive after 30 days with favourable neurological outcome. The patients who survived the first year lived also to 5 years after the event with favourable neurological and functional status. Conclusions The in-hospital cardiac arrest incidence on a large tertiary Swiss university hospital was 1.56 per 1000 patient admissions. After a cardiac arrest, about a third of the patients survived to 5 years with favourable neurological and functional status. Alarms unrelated to life-threatening situations are common and need to be taken into count within a low-threshold alarming system. Trial Registration: The trial was registered in clinicaltrials.gov (NCT02746640).

Abstract Background: Incidence of in-hospital cardiac arrest is reported to be 0.8 to 4.6 per 1,000 patient admissions. Patient survival to hospital discharge with favourable functional and neurological status is around 21%. The Bern University Hospital is a tertiary medical centre in Switzerland with a cardiac arrest team from the Department of Anaesthesiology and Pain Medicine that is available 24 h per day, 7 days per week. Due to lack of central documentation of cardiac arrest team interventions, the incidence, outcomes and survival rates of cardiac arrests are unknown. The aim was thus to record all cardiac arrest team interventions over 1 year, and to analyse the outcome and survival rates of adult patients after in-hospital cardiac arrests.Methods: We conducted a prospective single-centre observational study that recorded all adult in-hospital cardiac arrest team interventions over 1 year, using an Utstein-style case report form. The primary outcome was 30-day survival after in-hospital cardiac arrest. Secondary outcomes were return of spontaneous circulation, neurological status (after return of spontaneous circulation, after 24 h, after 30 days and 1 year), according to the Glasgow Outcomes Scale, and functional status at 30 days and 1 year, according to the Short-form-12 Health Survey.Results: The cardiac arrest team had 146 interventions over the study year, which included 60 non-life-threatening alarms (41.1%). The remaining 86 (58.9%) acute life-threatening situations included 68 (79.1%) as patients with cardiac arrest. The mean age of these cardiac arrest patients was 68 ±13 years, with a male predominance (51/68; 75.0%). Return of spontaneous circulation was recorded in 49 patients (72.1%). Over one-third of the cardiac arrest patients (27/68) were alive after 30 days with favourable neurological outcome. The patients who survived to 1 year after the event showed favourable neurological and functional status. Conclusions: The in-hospital cardiac arrest incidence on a large tertiary Swiss university hospital was 1.56 per 1,000 patient admissions. After a cardiac arrest, about a third of the patients survived to 1 year with favourable neurological and functional status. Early recognition and high-quality cardiopulmonary resuscitation provided by a well-organised team is crucial for patient survival.Trial Registration: The trial was registered in clinicaltrials.gov (NCT02746640).
