Therapies Thursday, August 1st, 2013STROKEAHA: July 30, 2013
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 (2005–2010) and the Canadian Discharge Abstract Database (2004–2010) 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. Read more
