The Assessment of Clinical and Economic Outcomes Associated with Stroke in Rural Emergency Departments

Abstract

Specific Aims: The purpose of this study was to assess the clinical and economic predictors associated with rural emergency department visits in stroke patients. Methods: The current research was a retrospective, observational, cohort study. Multivariate regression was used to assess data from the Agency for Healthcare Research and Quality (AHRQ) 2009 Nationwide Emergency Department Sample (NEDS). Inclusion criteria were at least 18 years of age and rural ED admission with principle diagnoses of stroke. Main Results: Significant results for risks included: Intubation for increased mortality (OR = 17.432, p = 0.001), increased length of stay (IRR = 1.643, p = 0.018) and increased charges (exp β = 2.289, p = < 0.001); myocardial infarction for increased mortality (OR = 1.969, p = 0.006), decreased charges (exp β = 0.862, p = 0.013) and decreased length of stay (IRR = 0.853, p = 0.001); moderate to severe liver disease for increased mortality (OR = 62.691, p = 0.001) and reduced length of stay (IRR = 0.517, p = 0.025); congestive heart failure for increased mortality (OR 1.978, p = 0.003) and increased charges (exp β = 1.118, p = 0.039); non-specific cancer (OR = 2.447, p = 0.017) and metastatic cancer (OR = 4.799, p = 0.016) for mortality; hemiplegia/paraplegia for increased charges (exp β = 1.173, p = < 0.001). Conclusion: The current study found a better understanding of national estimates of burden of illness to further define clinical decision rules for stroke in rural emergency departments.
