Background: It has been shown that individuals with lower socioeconomic status (SES) are more likely to develop cardiovascular disease despite improvements in other risk factors. We aim to assess the impact of socioeconomic status in patients hospitalized for non-ST elevation myocardial infarction (NSTEMI) in the United States.
Methods: This was a retrospective cohort study using the 2013 National Inpatient Sample (NIS). The inclusion criteria were age older than 18 years and an ICD-9 CM code for primary diagnosis of NSTEMI. SES was determined by the median household income for patient's ZIP code (group 1: low SES; group 2: high SES). Our outcomes included inpatient mortality, length of stay, percutaneous coronary intervention (PCI) rates, and hospital charges. Multivariate logistic regression was used to adjust for potential confounders including age, gender and the Charlson Comorbidity index.
Results: We included a total of 422,795 patients admitted with NSTEMI. The mean age was 68 years and 59% of patients were female. The adjusted likelihood of in-hospital mortality was higher in group 1. In the secondary outcomes, patients in group 1 had increased mean LOS. The likelihood of getting PCI was not different between the two groups. The average total hospital charges for group 1 was less compared to group 2.
Conclusions: Patients with lower socioeconomic status have increased rates of inpatient mortality with increased length of stay. Although, the likelihood of getting PCI is not associated with this factor.
