Details of the initial management of cardiac arrest occurring in the workplace in a French urban area

Cardiac Arrest Management in the Workplace: Improving but Not Enough?

The aim was to describe out-of-hospital cardiac arrest (OHCA) occurring in the workplace of a large emergency network, and compare the evolution of their management in the last 15 years. A retrospective study based on data from the Northern Alps Emergency Network compared characteristics of OHCA between cases in and out the workplace, and between cases occurring from January 2004 to December 2010 and from January 2011 to December 2017. Among the 15,320 OHCA cases included, 320 occurred in the workplace (2.1%). They were more often in younger men, and happened more frequently in an area with access to public defibrillation, had more often a shockable rhythm, had a cardiopulmonary resuscitation started by a bystander more frequently, and had a better outcome. Cardiopulmonary resuscitation started by a bystander was the only chain of survival link that improved for cases occurring after December 2010. Workplace OHCA seems to be managed more effectively than others; however, only a slight survival improvement was observed, suggesting that progress is still needed.

Awareness of cardiopulmonary resuscitation among parents of 3-year-old children

BACKGROUND

Out-of-hospital cardiac arrest (OHCA) in infants or toddlers mainly occurs at home. Therefore, parents should be able to perform immediate cardiopulmonary resuscitation (CPR) when they witness OHCA. The status of knowledge regarding CPR among parents, however, remains unclear. The aim of the present study was therefore to determine the factors associated with awareness of CPR in parents of 3-year-old children.

METHODS

We analyzed a subset of data from a population-based, cross-sectional survey that served as an evaluation of a national campaign for maternal and child health in Japan. The questionnaire was distributed to 32 897 parents who visited public health centers for medical check-ups for their children in 2013. Multivariate logistic regression analysis was carried out using the obtained demographic data.

RESULTS

Overall, 26 971 parents (82.0%) responded to the questionnaire. On multivariate logistic regression analysis, birth order of the child, age of the mother at delivery, awareness of medical facilities for emergency services at night or during the weekend, current occupation status of the mother, and current economic status were independently associated with CPR awareness. When the mother was employed but the parents felt economically insufficient, the probability of having CPR knowledge decreased by 19%. Regardless of the parents' economic stability, the probability of having CPR knowledge declined by >35% when the mother was unemployed.

CONCLUSIONS

The current occupation status of mothers and the current parent economic status should be considered when planning educational strategies regarding CPR training for parents.

Use of automated external defibrillators in US federal buildings: implementation of the Federal Occupational Health public access defibrillation program

OBJECTIVE

Federal Occupational Health (FOH) administers a nationwide public access defibrillation program in US federal buildings. We describe the use of automated external defibrillators (AEDs) in federal buildings and evaluate survival after cardiac arrest.

METHODS

Using the FOH database, we examined reported events in which an AED was brought to a medical emergency in federal buildings over a 14-year period, from 1999 to 2012.

RESULTS

There were 132 events involving an AED, 96 (73%) of which were due to cardiac arrest of cardiac etiology. Of 54 people who were witnessed to experience a cardiac arrest and presented with ventricular fibrillation or ventricular tachycardia, 21 (39%) survived to hospital discharge.

CONCLUSIONS

Public access defibrillation, along with protocols to install, maintain, and deploy AEDs and train first responders, benefits survival after cardiac arrest in the workplace.

Specific activity types at the time of event and outcomes of out-of-hospital cardiac arrest: a nationwide observational study

This study aimed to describe the characteristics of out-of-hospital cardiac arrest (OHCA) according to specific activity types at the time of event and to determine the association between activities and outcomes according to activity type at the time of event occurrence of OHCA. A nationwide OHCA cohort database, compiled from January 2008 to December 2010 and consisting of hospital chart reviews and ambulance run sheet data, was used. Activity group was categorized as one of the following types: paid work activity (PWA), sports/leisure/education (SLE), routine life (RL), moving activity (MA), medical care (MC), other specific activity (OSA), and unknown activity. The main outcome was survival to discharge. Multivariate logistic analysis for outcomes was used adjusted for potential risk factors (reference = RL group). Of the 72,256 OHCAs, 44,537 cases were finally analyzed. The activities were RL (63.7%), PWA (3.1%), SLE (2.7%), MA (2.0%), MC (4.3%), OSA (2.2%), and unknown (21.9%). Survival to discharge rate for total patients was 3.5%. For survival to discharge, the adjusted odds ratios (95% confidence intervals) were 1.42 (1.06-1.90) in the SLE group and 1.62 (1.22-2.15) in PWA group compared with RL group. In conclusion, the SLE and PWA groups show higher survival to discharge rates than the routine life activity group.
