In our low-risk population the majority of TIMI risk score differences were small however, 12% of TIMI risk scores differed by two or more points.Ĭonclusion: TIMI risk scores determined by ED providers in the setting of a busy ED frequently differ from scores generated by trained research investigators who complete them while not under the same pressure of an ED provider. Results: Of the 501 adult patients enrolled in the study, 29.3% of TIMI risk scores determined by ED providers and trained research investigators were generated using identical TIMI risk score variables. We examined provider type, patient gender, and TIMI elements for their effects on TIMI risk score discrepancy. Results: Event rates increased significantly as the TIMI risk score increased in the test cohort in TIMI 11B: 4.7 for a score of 0/1 8.3 for 2 13. Methods: This was an ED-based prospective observational cohort study comparing TIMI scores obtained by 49 ED providers admitting patients to an ED chest pain unit (CPU) to scores generated by a team of trained research investigators. We assessed whether TIMI risk scores obtained by ED providers in the setting of a busy ED differed from those obtained by trained research investigators. Most of the studies we reviewed relied on trained research investigators to determine TIMI risk scores rather than ED providers functioning in their normal work capacity. The TIMI Risk Score for UA/NSTEMI estimates mortality for patients with unstable angina and non-ST elevation myocardial infarction (MI). The original study showed 4.7 of patients with a score of 0 or 1 had adverse outcomes. Introduction: Several studies have attempted to demonstrate that the Thrombolysis in Myocardial Infarction (TIMI) risk score has the ability to risk stratify emergency department (ED) patients with potential acute coronary syndromes (ACS). A TIMI risk score of 0 or 1 does not equal zero risk of adverse outcome.
