O-022 Cardiac Arrest in the Workplace: Characteristics, Outcome and Use of Automated External Defibrillator

Introduction Context Workplace cardiac arrest (CA) is often associated with young age, presence of bystanders, quick initiation of cardiopulmonary resuscitation (CPR) and availability of automated external defibrillator (AED). Characteristics and outcome of patients with workplace CA and potential use of an AED were described from the perspective of an emergency medical service. Methods The Paris Sudden Death Center is a registry of all CA in Paris region. It was used to include for all patients aged 18 and over with a workplace-acquired CA from 01/04/2014 to 31/12/2022. Data on age, gender, presence of a control, initiation of CPR, use of an AED, duration of no/low-flow, patient outcome, and Cerebral Performance Categories (CPC) score at hospital discharge were collected. Results Six hundred and sixty-one patients were included. Most were men (87.9%), with a mean age of 52 (± 12) years. A bystander was often present (79.5%) and performed CPR in 82.7% of cases. AED use was less frequent in 2015 (15%) and peaked in 2020 (50%). Average no-flow and low-flow time were respectively 5.43 min (± 9.84) was 37.8 min (+/-33.9). Fifty-six percent of patients were admitted to hospital, and 40.5% were discharged alive, with a CPC score of 1 in 80.9% and 2 in 15.7% of cases. Discussion and conclusion Occurrence of CA in the workplace offers favorable management conditions, resulting in an overall survival rate of 22.7%. Training staff in the use of AEDs, offering first aid training and regular refresher courses are all ways of optimizing the chances of better managing a CA.
