Abstract
Background and Purpose—: The association among socioeconomic status, quality of care, and clinical outcome after stroke remains poorly understood. In a Danish nationwide follow-up study, we examined whether socioeconomic-related differences in acute stroke care occur and, if so, whether they explain socioeconomic differences in case-fatality and readmission risk. Methods—: Using population-based public registries, we identified and followed all patients aged ≤65 years admitted with stroke from 2003 to 2007 (n=14 545). We compared the proportion of patients receiving 7 specific processes of care according to income, educational attainment, and employment status. Furthermore, we computed 30-day and 1-year hazard ratios for death and readmission adjusted for patient characteristics and received processes of acute stroke care. Results—: For low-income patients and disability pensioners, the relative risk of receiving all of the relevant processes of care was 0.82 (95% CI, 0.78 to 0.86) and 0.83 (95% CI, 0.79 to 0.87), respectively, compared with high-income patients and employed patients. Adjusted 30-day and 1-year hazard ratios for death for unemployed patients were 1.57 (95% CI, 1.25 to 1.97) and 1.58 (1.32 to 1.88), respectively, compared with employed patients. Unemployed patients also had a higher risk of readmission. The differences in mortality and readmission risk remained after controlling for received processes of acute stroke care. Conclusions—: Low socioeconomic status was associated with a lower chance of receiving optimal acute stroke care. However, the differences in acute care did not appear to explain socioeconomic differences in mortality and readmission risk.
