In-Hospital Cardiac Arrest: Patient Characteristics and Factors Influencing Survival and Neurologic Outcomes

Objective: We aimed to determine the characteristics of in-hospital cardiac arrest (IHCA) patients, as well as the factors influencing survival to discharge and good neurologic outcome.Methods: We examined patients who experienced IHCA from January 1, 2011, to December 31, 2013, in Soonchunhyang University Seoul Hospital. They were divided into a survival group and non-survival group. The patient characteristics, including age, sex, comorbid disease, arrest time, arrest location, witnessed arrest, monitoring, arrest cause, arrest rhythm, and cardiopulmonary resuscitation (CPR) duration, were compared between the groups. Moreover, we assessed the factors associated with survival to discharge and good neurologic outcomes by using multivariate logistic regression analysis.Results: In total, 453 patients of IHCA were observed. The comorbidities in the survival group included neurologic disease (P < 0.001), arrhythmia (P = 0.001), and myocardial infarction (P = 0.032), pneumonia (P = 0.016). Other characteristics included cardiac arrest at daytime (P = 0.032), cardiogenic arrest cause (P = 0.019), and CPR duration < 15 minutes (P < 0.001). The factors associated with survival to discharge included comorbid neurologic disease (odds ratio [OR], 2.191; P = 0.031), arrhythmia (OR, 3.027; P = 0.009), pneumonia (OR, 3.243; P = 0.002), and CPR duration < 15 minutes (OR, 9.638; P < 0.001). The factors influencing good neurologic outcomes included age < 65 years (OR, 3.158; P = 0.007), comorbid disease as arrhythmia (OR, 4.921; P = 0.001), pneumonia (OR, 4.551; P = 0.001), hypotension (OR, 4.264; P = 0.021), and CPR duration < 15 minutes (OR, 6.652; P = 0.001).Conclusion: The factors influencing survival to discharge and good neurologic outcomes among IHCA patients included comorbidities, arrest cause, and CPR duration.

Hospital Cardiac Arrest

Out-of-hospital cardiac arrest (OHCA) due to drowning carries high morbidity and mortality. There are a few studies on drowning-related out-of-hospital cardiac arrest (OHCA), in which patients are followed from the scene to hospital discharge. This study aims to compare patient characteristics between the survival group and mortality group of OHCA due to drowning. OHCA due to drowning cases were selected from the North America Termination of Resuscitation Association database between 2011 and 2015. The retrospective analysis of epidemiological characteristics and clinical features of all OHCA patients were performed. Of the 17,094 OHCA cases in the registry, 54 cases of OHCA due to drowning were included in this study. Among the 54 OHCAs due to drowning, 7 (13.0%) survived, while 47 (87.0%) died. Compared to the mortality group, the survival group had a higher bystander witness rate (57.1% versus 17.0%, p < 0.05 ), higher asystole rate (42.9% versus 78.7%, p < 0.05 ), and higher mild therapeutic hypothermia rate (28.6% versus 2.1%, p < 0.05 ). In addition, a large proportion of survivors were children (71.4%) and males (71.4%). Survival among OHCA’s due to drowning was found to be improved with a higher bystander rate, higher asystole rate, and higher mild hypothermia rate. In addition, children and males comprised the majority of survivors.

Abstract Background Mechanical circulatory support (MCS) with either extracorporeal membrane oxygenation or Impella has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). The objective of this study was to describe the gradual implementation, survival and adherence to the national consensus with respect to use of MCS for OHCA in Denmark, and to identify factors associated with outcome. Methods This retrospective, observational cohort study included patients receiving MCS for OHCA at all tertiary cardiac arrest centers (n = 4) in Denmark between July 2011 and December 2020. Logistic regression and Kaplan–Meier survival analysis were used to determine association with outcome. Outcome was presented as survival to hospital discharge with good neurological outcome, 30-day survival and predictors of 30-day mortality. Results A total of 259 patients were included in the study. Thirty-day survival was 26%. Sixty-five (25%) survived to hospital discharge and a good neurological outcome (Glasgow–Pittsburgh Cerebral Performance Categories 1–2) was observed in 94% of these patients. Strict adherence to the national consensus showed a 30-day survival rate of 30% compared with 22% in patients violating one or more criteria. Adding criteria to the national consensus such as signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow < 100 min, pH > 6.8 and lactate < 15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (RR 1.20, 95% CI 1.03–1.41), initial pH < 6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels > 15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had reduced risk of 30-day mortality (RR 0.63, 95% CI 0.52–0.76). Conclusions A high survival rate with a good neurological outcome was observed in this Danish population of patients treated with MCS for OHCA. Stringent patient selection for MCS may produce higher survival rates but potentially withholds life-saving treatment in a significant proportion of survivors.

ObjectiveThe purpose of this study was to assess the trends in outcomes of out-of-hospital cardiac arrest (OHCA) in Beijing over 5 years.DesignCross-sectional study.MethodsAdult patients with OHCA of all aetiologies who were treated by the Beijing emergency medical service (EMS) between January 2013 and December 2017 were analysed. Data were collected using the Utstein Style. Cases were followed up for 1 year. Descriptive statistics were used to characterise the sample and logistic regression was performed.ResultsOverall, 5016 patients with OHCA underwent attempted resuscitation by the EMS in urban areas of Beijing during the study period. Survival to hospital discharge was 1.2% in 2013 and 1.6% in 2017 (adjusted rate ratio=1.0, p for trend=0.60). Survival to admission and neurological outcome at discharge did not significantly improve from 2013 to 2017. Patient characteristics and the aetiology and location of cardiac arrest were consistent, but there was a decrease in the initial shockable rhythm (from 6.5% to 5.6%) over the 5 years. The rate of bystander cardiopulmonary resuscitation (CPR) increased steadily over the years (from 10.4% to 19.4%).ConclusionSurvival after OHCA in urban areas of Beijing did not improve significantly over 5 years, with long-term survival being unchanged, although the rate of bystander CPR increased steadily, which enhanced the outcomes of patients who underwent bystander CPR.

Hospital Cardiac Arrest

Introduction: It is well established that AEDs improve outcome in shockable out-of-hospital cardiac arrest (OHCA). An increasing proportion (now the majority) of OHCAs present with non-shockable rhythms. Survival from non-shockable OHCA depends on high-quality CPR in transit to definitive care. Studies of AED use in non-shockable in-hospital arrest (as opposed to OHCA) have shown reduced survival with AED application possibly due to CPR interruptions to apply pads and perform rhythm analysis. We sought to determine whether AED application in non-shockable public, witnessed OHCA has a significant association with survival to discharge. Methods: This is a retrospective analysis of OHCA from 2010-2015 at 10 Resuscitation Outcomes Consortium centers. All adult, public, witnessed non-shockable OHCAs were included. Non-shockable arrest was defined as no shock delivered by the AED or by review of defibrillator tracings (10%). The initial rhythm on EMS arrival was used to confirm the rhythm. The primary outcome was survival to hospital discharge with favorable neurological status (modified rankin score <3). The OR was adjusted for the Utstein variables. Results: During the study period there were 1,597 non-shockable public, witnessed OHCA, 9.8% of which had an AED applied. The initial rhythm on EMS arrival was PEA or asystole in 86% of cases. Significantly more OHCA in the AED applied group had CPR performed. 6.5% of those without an AED applied survived with favorable neurologic status compared to 9% with an AED. After adjustment for the Utstein variables including bystander CPR, the aOR for survival with favorable neurologic outcome was 1.38 (95% CI:0.72-2.65). Conclusion: After adjusting for patient characteristics and bystander CPR, the application of an AED in non-shockable public witnessed OHCA had no significant association with survival or neurological outcome supporting the relative safety and potential benefit of AED application in non-shockable OHCA.
