Network of Automated External Defibrillators in Poland before the SARS-CoV-2 Pandemic: An In-Depth Analysis

Sudden cardiac arrest (SCA), which causes more than half of all cardiovascular related deaths, can be regarded as a common massive global public health problem. Analyzing out-of-hospital cardiac arrest (OHCA) cases, one of the key components is automatic external defibrillators (AEDs).

The aim of this study was to analyze the use and distribution of AEDs in Polish public places.

The data were analyzed by using the Excel and R calculation programs.

The data represents 120 uses of automatic external defibrillators used in Polish public space in the period 2008-2018. The analysis describes 1165 locations of AEDs in Poland. It was noted that the number of uses in the period 2010-2016 fluctuated at a constant value, with a significant rise in 2017. When analyzing the time of interventions in detail the following was noted: the highest percentage of interventions was observed in April, and the lowest in November; the highest number of interventions was observed on a Friday, while the least number of interventions was observed on a Sunday; most occurred between 12:00 to 16:00, and least between 20:00 to 8:00.

The observed growth in the number of cases of AED use in public places is associated with the approach to training, the emphasis on public access to defibrillation, and, therefore, the growth of social awareness. This study will be continued. The next analysis would include 2020-2022 and would be a comparative analysis with the current research.
