“…Our data suggests some of this variation may be explained by the regions examined and in the periods of time studied. We found significant sub-State variation in OHCA incidence rates, which is consistent with reports across census tracts in the United States [26][27][28]. To our knowledge, ours is the first study to include rural regions with low and very low density populations (<200/km2), some of which had the highest incidence rates across the state.…”

BackgroundRates of out-of-hospital cardiac arrest (OHCA) and bystander cardiopulmonary resuscitation (CPR) have been shown to vary considerably in Victoria. We examined the extent to which this variation could be explained by the sociodemographic and population health characteristics of the region.MethodsUsing the Victorian Ambulance Cardiac Arrest Registry, we extracted OHCA cases occurring between 2011 and 2013. We restricted the calculation of bystander CPR rates to those arrests that were witnessed by a bystander. To estimate the level of variation between Victorian local government areas (LGAs), we used a two-stage modelling approach using random-effects modelling.ResultsBetween 2011 and 2013, there were 15 830 adult OHCA in Victoria. Incidence rates varied across the state between 41.9 to 104.0 cases/100 000 population. The proportion of the population over 65, socioeconomic status, smoking prevalence and education level were significant predictors of incidence in the multivariable model, explaining 93.9% of the variation in incidence among LGAs. Estimates of bystander CPR rates for bystander witnessed arrests varied from 62.7% to 73.2%. Only population density was a significant predictor of rates in a multivariable model, explaining 73% of the variation in the odds of receiving bystander CPR among LGAs.ConclusionsOur results show that the regional characteristics which underlie the variation seen in rates of bystander CPR may be region specific and may require study in smaller areas. However, characteristics associated with high incidence and low bystander CPR rates can be identified and will help to target regions and inform local interventions to increase bystander CPR rates.

“…The lower incidence in the area serviced by SJANT is particularly surprising given that the Northern Territory has the largest proportion of Indigenous people [15] and it is known that the incidence of cardiovascular disease in Indigenous people is substantially higher than that of non-Indigenous people [24]. This regional variation may also be explained by an accompanying variation in underlying risk of OHCA; studies have demonstrated that a large proportion of regional variation in incidence can be explained through socioeconomic factors and health characteristics of the underlying population [25,26].…”
