Abstract WP331: The Effect of ABCD2 Score as a Triage Tool for TIA Patients on 90 Day Hospital Re-Admission

Introduction and Objectives: After a transient ischemic attack, there is a 90 day increased risk of stroke that can be predicted by ABCD2 score. A TIA clinic for low risk (ABCD2 score <4) was established at Kaiser Permanente. We hypothesized that patients seen in this clinic would have the same 90 day re-admission rate as those evaluated inpatient. Methods: At Kaiser Permanente LAMC, a TIA clinic was established in November 2, 2010. TIAs were triaged by a Neurologist who calculated the ABCD2 score. Patients were referred to the TIA clinic with a score <4 and evaluated inpatient if score ≥4. Patient data was abstracted for all patients with a TIA clinic referral placed between November 2, 2010 and February 28, 2013 (182 charts) and 148 were included in the analysis. Patients were excluded if the ABCD2 score could not be calculated or referral was inappropriate. The ICD-9 code was used to abstract patients with TIA for the same time period (145 charts) and 58 patients were included. Non-Kaiser members and p...
