Abstract 3898: Predictors Of Admissions In Patients Presenting To Emergency Department With Transient Ischemic Attacks In United States- A National Survey
Background: The estimates of patients who present with transient ischemic attacks (TIA) in the emergency departments (ED) of United states and their disposition including factors that determine hospital admission are not well understood.
Objective: We used a nationally representative database to determine the rate and predictors of admission in TIA patients presenting to the ED.
Methods: We analyzed the data from National Emergency Department Sample (NEDS 2006-2007) for all patients presenting with primary diagnosis of TIAs in the United States. Samples were weighted to provide national estimates of TIA hospitalizations and identify factors that increase the odds of hospital admission including age, sex, type of insurance, hospital type (urban teaching, urban nonteaching and non urban). Multivariate logistic regression analysis was used to identify predictors of hospital admission.
Results: Of the total of 631750 patients presenting with TIA to the EDs in a period of two years in US, 41, 9447 (66.4%) were admitted to the hospital. In the multivariate analysis, independent factors associated with hospital admissions were women (odds ratio[OR] 1.042, 95% confidence interval [CI] 1.014-1.071, p =0.003) , Medicare insurance type (OR 0.82, 95% CI 0.88-0.93, p<0.0001), and urban non-teaching hospital ED (OR 0.825, 95% CI 0.778-0.875, p<0.0001).
Conclusion: Approximately 70% of all patients presenting with TIAs to the EDs within United States are admitted. Factors unrelated to patients condition such as insurance status and ED affiliated hospital type play an important role in the decision to admit TIA patients to the hospitals.
