An Analysis of Transient Ischemic Attack Practices: Does Hospital Admission Improve Patient Outcomes?

IntroductionImmediate treatment has been shown to decrease the recurrence of cerebrovascular accidents following transient ischemic attacks (TIA), prompting the use of a specialized neurologic emergency department (Neuro ED) to triage patients. Despite these findings, there is little evidence supporting the notion that hospital admission improves post-TIA outcomes. Through the lens of a Neuro ED, this retrospective chart review of TIA patients examines whether hospital admission improves 90-day outcomes.Materials and MethodsTwo hundred sixty charts of patients discharged with TIA diagnosis were reviewed. These charts encompassed patients with TIA who presented to a main emergency department (ED) or Neuro ED from January 2014 to April 2015. Demographic information, admission ABCD2 scores, admission National Institutes of Health Stroke Scale scores, and admission Modified Rankin Scale, and reason for any return visits within 90 days were collected.ResultsThis review shows that patients triaged by the Neuro ED were admitted at a lower rate than those seen by the standard ED. Further, patients triaged by the Neuro ED experienced lower readmission and recurrence of stroke or TIA within 90 days.ConclusionsThese results provide preliminary support for the notion that discharging appropriate TIA patients, with adequate follow-up, will not adversely affect the recurrence of TIA or stroke within 90 days.
