Cardiac Arrest in the Operating Room

Audit of defibrillators at an urban public sector hospital

Introduction

Life-threatening emergencies are not limited to the emergency department. Any delay in intervention during an emergency often culminates into a poor outcome. Early electrical defibrillation is one of the most important interventions in patients with cardiac arrest. This study aimed to conduct a clinical audit of defibrillator devices at an urban public sector hospital in Johannesburg.

Methods

All defibrillator devices within various areas of the hospital were assessed. Device characteristics were recorded into a data collection sheet and subjected to further analysis.

Results

This study assessed 112 out of 123 areas in the hospital with a total of 143 defibrillators comprising 139(97.2%) manual external defibrillators (MED) and four(2.8%) automated external defibrillators (AED). MEDs were located in the general wards (n=52, 37.4%), theatre complex (n=25, 17.9%), high dependency areas (n=27, 19.4%) and non-sleepover areas (n=35, 25.2%). Daily checklist books were available for 101 (72.7%) MEDs, 26 (18.7%) had at least once daily documented checks over a 5-day period while 57 (41.0%) had been serviced in the last 12 months. Seven MEDs (4.9%) and one AED (0.7%) had critical problems.

Conclusion

Compliance with regard to the availability of defibrillator checklist books, conducting and recording of daily defibrillator checks, timely service maintenance of defibrillators and identification of critical device problems was suboptimal in this study. There is a need for ongoing training of hospital staff as well as the establishment of systems to prevent potential adverse consequences due to device failure.
