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.

Purpose: Little is known regarding patterns of resuscitation care in patients with advanced cancer who suffer in-hospital cardiac arrest (IHCA). Methods: In the Get With The Guidelines – Resuscitation registry, 47,157 adults with IHCA with and without advanced cancer (defined as the presence of metastatic or hematologic malignancy) were identified at 369 hospitals from April 2006 through June 2010. We compared rates of return of spontaneous circulation (ROSC) and survival to discharge between groups using multivariable models. We also compared duration of resuscitation effort and resuscitation quality measures. Results: Overall, 6,585 patients with IHCA (14.0%) had advanced cancer. Patients with advanced cancer had lower multivariable-adjusted rates of ROSC (52.3% [95% CI, 49.5% to 55.3%] v 56.6% [95% CI, 53.8% to 59.5%]; P < .001) and survival to discharge (7.4% [95% CI, 6.6% to 8.4%] v 13.4% [95% CI, 12.1% to 14.8%]; P < .001). Among nonsurvivors who died during resuscitation, patients with advanced cancer had better performance on most resuscitation quality measures. Among patients with ROSC, patients with advanced cancer were made Do Not Attempt Resuscitation (DNAR) more frequently within 48 hours (adjusted relative risk, 1.30 [95% CI, 1.24 to 1.37]; P < .001). Adjustment for DNAR status explained some of the immediate effect of advanced cancer on survival; however, survival remained significantly lower in patients with cancer. Conclusion: Patients with advanced cancer can expect lower survival rates after IHCA compared with those without advanced cancer, and they are more frequently made DNAR within 48 hours of ROSC. These findings have important implications for discussions of resuscitation care wishes with patients and can better inform end-of-life discussions.

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.

Over Time

Introduction: Survival after in-hospital cardiac arrest (IHCA) is increasing. In the Get-With-The-Guidelines-Resuscitation (GWTG-R) registry, longer median CPR duration in patients not achieving ROSC is associated with higher survival rates at the hospital level. We analyzed trends over time in median CPR duration by hospital in patients who achieved ROSC and those who did not, and stratified this analysis by age, gender and race. Methods: We included adult IHCA cases in GWTG-R from 2001-2017, excluding data from a given hospital and year if fewer than 5 eligible arrests were recorded. A nonparametric test for trend was done to evaluate median CPR duration over time in those with and without ROSC, in all patients and in groups stratified by age (<60, 61-80 and >80 years), gender, and race (white and black). Linear regression was done to evaluate the amount of change per year. Association with survival was tested using Pearsons correlation. Results: Of 359,107 IHCA events, 31,189 were excluded, leaving 327,918 for analysis. Over time, there was a significant increase in median CPR duration in patients who did not achieve ROSC, and a decrease in those who did attain ROSC.(Fig.) These trends persisted when stratified by gender, race and age. Each year was associated with a decrease in median CPR duration of 0.37 min (95% CI -0.41 to -0.33 min) in those with ROSC and an increase of 0.29 min (95% CI 0.25 to 0.33 min) in those without. There was a small but significant correlation between median CPR duration in those without ROSC and adjusted survival by hospital over time (r=0.224, p<0.0001). Conclusions: In the GWTG-R registry, median duration of CPR is decreasing over time in patients achieving ROSC, but increasing in those not achieving ROSC. The increasing trend in CPR duration in those without ROSC correlates positively with the trend in survival. Whether the increase in median CPR duration in those without ROSC is contributing causally to improvements in survival warrants further study.

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.

Background and Objectives: It is estimated that over 200,000 adults experience in-hospital cardiac arrest each year. Overall survival to discharge has remained relatively unchanged for decades and survival rates remain at about 20% (Elenbach et al., 2009). Get With The Guidelines-Resuscitation (GWTG-R) is an in-hospital quality improvement program designed to improve adherence to evidence-based care of patients who experience an in-hospital resuscitation event. GWTG-R focuses on four achievement measures. The measures for adult patients include time to first chest compression of less than or equal to one minute, device confirmation of correct endotracheal tube placement, patients with pulseless VF/VT as the initial documented rhythm with a time to first shock of less than or equal to two minutes, and events in which patients were monitored or witnessed at the time of cardiac arrest. The objective of this abstract is to examine the association between hospital adherence to GWTG-R and in-hospital cardiac arrest survival rates. Methods: A retrospective review of adult in-hospital cardiopulmonary arrest (CPA) patients (n=1849) from 21 Michigan, Illinois, and Indiana hospitals using the GWTG-R database was conducted from January 2014 through December 2014. This study included adult CPA patients that did and did not survive to discharge. Results: The review found that hospitals that had attained 84.6% or higher thresholds in all four achievement measures for at least one year, which is award recognition status, had a significantly improved in-hospital CPA survival to discharge rate of 29.6%. Hospitals that did not obtain award status had a CPA survival to discharge rate of 24.3%. The national survival rate for in-hospital adult CPA survival to discharge is 20%. Hospitals that did not achieve award recognition status still demonstrated improvement in survival rate when compared to the national survival rate, indicating the importance of a quality improvement program such as GWTG-R. No significant difference was found between in-hospital adult CPA survival rate and race between GWTG-R award winning and non-award winning hospitals. Hospitals that earned award recognition from GWTG-R had a survival to discharge rate of 30.2% for African Americans and 29.6% for whites. Hospitals that were did not earn award recognition from GWTG-R had a survival to discharge rate of 20.0% for African Americans and 20.1% for whites. Conclusions: Survival of in-hospital adult CPA patients improved significantly when GWTG-R measures are adhered to. Survival of in-hospital adult CPA patients also improves with implementation of GWTG-R. It is crucial that hospitals collect and analyze data regarding resuscitation processes and outcomes. Quality improvement measures can then be implemented in order to assist with improving in-hospital CPA survival rates.

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).

Objective: In cardiac arrest cases, high quality cardiopulmonary resuscitation and effective chest compression are vital issues in improving survival with good neurological outcomes. In this study, we investigated the effect of mechanical chest compression devices on 30- day survival in out-of-hospital cardiac arrest. Materials and Methods: This retrospective case-control study was performed on patients who were over 18 years of age and admitted to the emergency department for cardiac arrest between January 1, 2016 and January 15, 2018. Manual chest compression was performed to the patients before January 15, 2017, and mechanical chest compression was performed after this date. Return of spontaneous circulation, hospital discharge, and 30-day survival rates were compared between the groups of patients in terms of chest compression type. In this study, the LUCAS-2 model piston-based mechanical chest compression device was used for mechanical chest compressions. Results: The rate of return of spontaneous circulation was significantly lower in the mechanical chest compression group (11.1% vs 33.1%; p < 0.001). The 30-day survival rate was higher in the manual chest compression group (6.8% vs 3.7%); however, this difference was not statistically significant (p = 0.542). Furthermore, 30-day survival was 0% in the trauma group and 0.6% in the patient group who underwent cardiopulmonary resuscitation for over 20 minutes. Conclusion: It can be seen that the effect of mechanical chest compression on survival is controversial; studies on this issue should continue and, furthermore, studies on the contribution of mechanical chest compression on labor loss should be conducted.
