“…This is explained by correlations between explanatory variables, such that when we controlled for other risk factors in the multivariable model, higher education levels were associated with increased incidence of OHCA. This finding is contrary to an existing study that demonstrated no significant association between education level and OHCA incidence in univariate analyses 23. In our region, a recent report found higher levels of education to be associated with longer times in deciding to seek medical attention following the onset of acute coronary symptoms,24 a patient group that are most likely to experience OHCA.…”

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.

Public-access defibrillation programs have thus been developed to make automatic external defibrillators (AEDs) publicly available, allowing rapid early defibrillation. 11-17Although the benefits of AED are undeniable, public use rates remain very low, 4,15,18 and thus the effectiveness of such programs could be dramatically improved. One of the key issues is the disparity between the locations of AEDs and SCAs. In Paris, although AED deployment in the community, which started in 1993 with the progressive equipping of EMS ambulances, has been particularly active over the last decade, the choice of where to install AEDs in public places has been driven mainly by empirical considerations (local unguided initiatives). Recent studies have already pointed out the limitations of such an approach, calling for an evidence-based strategy.

“…15 CAR models have been widely used to map health outcomes at a population level and to identify relations with covariates. 8,15,16 Individuals living in close proximity are more likely to have the same outcome than individuals living farther apart. Unlike Bayesian hierarchical modeling, traditional regression methods fail to account for such spatial correlation patterns which could lead to bias in regression parameter estimates, under-estimation of standard errors, very narrow confidence intervals and potentially incorrect inferences regarding exposure-outcome associations.…”

“…7 Previous evidence suggested a significant regional variation in the incidence of OHCA events in Singapore. 8 One local study reported significantly poor survival outcomes among residential OHCA cases. 9 However, the extent to which areas vary in BCPR and survival rates among residential OHCA cases remains unknown in Singapore.…”
