Regions of High Out-Of-Hospital Cardiac Arrest Incidence and Low Bystander CPR Rates in Victoria, Australia

摘要: Background Out-of-hospital cardiac arrest (OHCA) remains a major public health issue and research has shown that large regional variation in outcomes exists. Of the interventions associated with survival, provision of bystander CPR is one most important modifiable factors. The aim this study to identify census areas high incidence OHCA low rates Victoria, Australia Methods We conducted an observational using prospectively collected population-based data from state Victoria Australia. Using ArcGIS (ArcMap 10.0), we linked location dispatch coordinates (longitude latitude) Victorian Local Government Areas (LGAs). We used Bayesian hierarchical models random effects on each LGA provide shrunken estimates rates. Results Over period there were 31,019 adult attended, which 21,436 (69.1%) cases presumed etiology. Significant among LGAs was observed. There 3 fold difference rate between lowest highest LGAs, ranging 38.5 115.1 per 100,000 person-years. overall for witnessed OHCAs 62.4%, increasing 56.4% 2008–2010 68.6% 2010–2013. 25.1% absolute LGAs. Conclusion Significant exists throughout Victoria. Regions participation can be identified would make suitable targets improve rates.
