Continuation of CPR on admission to emergency department after out-of-hospital cardiac arrest. Occurrence, characteristics and outcome

Cardiac arrest is a medical emergency with a poor prognosis. Patient characteristics and outcomes are associated with location and are traditionally categorized into out-of-hospital cardiac arrest (OHCA) or in-hospital cardiac arrest (IHCA). Increasing evidence has revealed that cardiac arrest occurring in the emergency department is distinct from OHCA or IHCA in other locations in hospitals, but most academic publications combine these populations and apply the knowledge arising from OHCA or IHCA to patients with emergency department cardiac arrest (EDCA). The aim of this study was to identify the research direction of EDCA in the past 20 years and to analyze the characteristics and content of academic publications. We searched the MEDLINE and EMBASE databases for eligible articles until May 30, 2021. Two independent reviewers extracted data by using a customized form to record crucial information, and any conflicts between the two reviewers were resolved through discussion with another independent reviewer. The aggregated data underwent a scoping review and analyzed qualitatively and quantitatively. In total, 52 original articles investigating EDCA were included; only 15 articles simply focused on EDCA, while other articles involved OHCA or IHCA simultaneously. There were 3 articles discussing the relationship of overcrowdedness and EDCA, 12 articles for prediction and risk factors associated with EDCA, 15 articles for epidemiology and prognosis, and 22 articles for specific diagnostic or resuscitation skills with regard to EDCA. Studies focusing on EDCA are increasing but still scarce. Applying the knowledge arising from OHCA or IHCA to EDCA is questionable, and research focused on EDCA is necessary. ED overcrowdedness-associated EDCA and prediction models for EDCA are essential topics that need further investigation.

Introduction: Neurological outcomes and the appropriate duration from call receipt to termination of resuscitation (TOR) in patients with out-of-hospital cardiac arrest (OHCA) could differ according to patient characteristics. Hypothesis: We hypothesized that a prediction chart comprising prehospital variables, including age, could be useful for predicting neurological outcomes and determining the time to TOR in the field or at the emergency department. Methods: We evaluated 19,829 elderly patients with OHCA (age ≥65 years) of cardiac origin who achieved prehospital return of spontaneous circulation (ROSC). Data were obtained from the prospectively recorded All-Japan Utstein Registry between 2011 and 2016. Patients with OHCA witnessed by emergency medical service providers were excluded. The primary outcome was 1-month neurologically intact survival, defined as a cerebral performance category (CPC) score of 1-2. Patients with OHCA were divided into 12 groups according to shockable rhythm (YES/NO), witness status (YES/NO), and age (65-74, 75-89, or ≥90 years). The time from call receipt to ROSC was calculated and categorized by 5-min intervals. The time from call receipt to ROSC at which the probability of 1-month CPC 1-2 decreased to <1% was defined as the call to TOR duration. Results: The overall 1-month CPC 1-2 rate was 18.9% (n = 3,756). When stratified by patient characteristics, the 1-month CPC 1-2 rates ranged from 52.3% in patients aged 65-74 years with shockable rhythm and witnessed OHCA (best-case scenario) to 1.6% in patients aged ≥90 years with non-shockable rhythm and un-witnessed OHCA (worst-case scenario). The corresponding call to TOR duration ranged from 35 to 10 min (Table). Conclusions: Neurological outcomes and the appropriate call to TOR duration differed according to patient characteristics, including age. Our prediction chart for elderly patients with OHCA could be useful for determining TOR in the field or at the emergency department.

Introduction The concept of the chain of survival is widely accepted. The four links viz. early access, early cardiopulmonary resuscitation (CPR), early defibrillation and early Advanced Cardiac Life Support (ACLS) are related to survival after pre-hospital cardiac arrest. Owing to the dismal survival-to-discharge figures locally, we conducted this study to identify any weaknesses in the chain, looking in particular at bystander CPR rates and times to Basic Cardiac Life Support (BCLS) and ACLS. Methods and materials A retrospective cohort study was conducted in the Emergency Department of an urban tertiary 1500-bed hospital. Over a 12-month period, all cases of non-trauma out-of-hospital cardiac arrest were evaluated. Results A total of 142 cases of non-trauma out-of-hospital cardiac arrest were identified; the majority being Chinese (103/142, 72.5%) and male (71.8%) with a mean age of 64.3±7.8 years (range 23–89 yrs). Most patients (111/142, 78.2%) did not receive any form of life support until arrival of the ambulance crew. Mean time from collapse to arrival of the ambulance crew and initiation of BCLS and defibrillation was 9.2±3.5 minutes. Mean time from collapse to arrival in the Emergency Department (and thus ACLS) was 16.8±7.1 minutes. Three patients (2.11%) survived to discharge. Conclusion There is a need to (i) facilitate layperson training in bystander CPR, and (ii) enhance paramedic training to include ACLS, in order to improve the current dismal survival outcomes from out-of-hospital cardiac arrest in Singapore.
