Title: The analyze of cardiac arrest in public places in the centre of Krakow


Purpose of this study: To analyse and compare the characteristics of cardiac arrests (CAs) that presented in public places in the central public areas of the city of Kraków with CAs that arose in private homes, including determination of the locations in which cardiac arrests (CAs) occurred most often. Materials and methods: This study was a retrospective analysis of local EMS cardiac arrest reports. The first group comprised all cases of CA that had resulted in EMS calls to the central public areas of the city of Kraków from 1 st January 1997 to 31 st December 2001. The second group consisted of all cases of CA in patient's homes from 1st January 1997 to 30th June 1999. The public places were grouped into 21 categories; an annual incidence of CA per site was calculated for each category except for "from the streets", as this was not a specific enough geographical location. Results: During the study period 576 CAs occurred in first group and 1069 CAs occurred in second group. The comparison of both groups showed the following differences, all of which were statistically significant. Comparing CAs in public places with CAs in private homes: CA occurred mare often in men (65,6% vs. 53,3%), the victims were younger (average age 65,1yr vs, 70,7yr), witnesses were more often present (50,3% vs. 31,8%), the CA rhythm could mare often be treated by defibrillation (22,9% vs. 9,3%), the ; CA was mare commonly cardiological in origin (38,8% vs. 30,6%) and bystander BLS was more frequently begun (14,9% vs, 5,5%). lt was seen that a return of spontaneous circulation was observed in 16,3% of cases of CA in public places but only in 6, 1 % of cases of CA in private houses (p<0,001 ). In following public places (from the 21 studied) the frequency of CA occurring in the single location was higher than one case per five years: the hostel for drunken people, old people's homes, homeless people's shelters, the law courts, cemeteries, railway and bus stations, prisons, churches, and big department stores. Conclusions: The characteristics of CA in public places are significantly different from CA in private homes. As public area CAs could more often be treated with defibrillation, are more likely to be witnessed, are younger victims and have more bystander intervention (all of which are known to improve survival from CA), and as there are places within Kraków's central public areas where CA occurred especially often, this might suggest a justification for targeting Public Access Automated External Defibrillators to those particular locations.
