“…17,18 Patients with SAH in the United States presented with greater comorbid burden compared with Canadian patients. The effect of SES was more pronounced in the United States than in Canada; a finding consistent with previous comparative studies that demonstrated stronger link between SES and overall population health 19,20 and disease-specific outcomes 21 in the United States compared with Canada. It is possible that Canada's more inclusive publicly funded health insurance coverage facilitated a relatively better access to treatment for comorbid conditions and improved chances of better outcomes after SAH among lower SES groups.…”

Background and Purpose-Studies in the United States and Canada have demonstrated socioeconomic gradients in outcomes of acute life-threatening cardiovascular and cerebrovascular diseases. The extent to which these findings are applicable to subarachnoid hemorrhage is uncertain. This study investigated socioeconomic status-related differences in risk of inpatient mortality and use of institutional postacute care after subarachnoid hemorrhage in the United States and Canada. Methods-Subarachnoid hemorrhage patient records in the US Nationwide Inpatient Sample database (2005)(2006)(2007)(2008)(2009)(2010) and the Canadian Discharge Abstract Database (2004Database ( -2010 were analyzed separately, and summative results were compared. Both databases are nationally representative and contain relevant sociodemographic, diagnostic, procedural, and administrative information. We determined socioeconomic status on the basis of estimated median household income of residents for patient's ZIP or postal code. Multinomial logistic regression models were fitted with adjustment for relevant confounding covariates. Results-The cohort consisted of 31 631 US patients and 16 531 Canadian patients. Mean age (58 years) and crude inpatient mortality rates (22%) were similar in both countries. A significant income-mortality association was observed among US patients (odds ratio, 0.77; 95% CI, 0.65-0.93), which was absent among Canadian patients (odds ratio, 0.97; 95% CI, 0.85-1.12). Neighborhood income status was not significantly associated with use of postacute care in the 2 countries. Conclusions-Socioeconomic status is associated with subarachnoid hemorrhage inpatient mortality risk in the UnitedStates, but not in Canada, although it does not influence the pattern of use of institutional care among survivors in both countries.

“…1 However, that they restricted themselves to proposing solutions such as targeted training for cardiopulmonary resuscitation and placement of automated external defibrillators is disappointing. Surely, addressing low socioeconomic status itself has a role to play in reducing mortality from sudden cardiac arrest.…”

“…The study by Reinier and colleagues published in the CMAJ has tested the hypothesis that environmental factors, such as those found in North American neighbourhoods with lower socioeconomic status, are associated with a higher incidence of sudden cardiac arrest. 2 The high incidence of cardiac arrest is recognized as the predominant mechanism of sudden cardiac death, especially among patients with coronary artery disease. As such, medical scientists and clinicians have sought ways of predicting and preventing these events.…”

“…9 Reinier and colleagues report that the incidence of sudden cardiac arrest is higher in poorer neighbourhoods in North American metropolitan areas. 2 These results are not surprising -cardiovascular and cardiac mortality have been shown to be higher in populations with lower socioeconomic status, 8,9 and approximately one half of cardiac deaths are sudden. In fact, almost all adverse outcomes, including mortality due to cancer, 10 are higher in groups with the lowest socioeconomic status.…”
