The impact of high-sensitivity troponin implementation on hospital operations and patient outcomes in 3 tertiary care centers.

Objective: High-sensitivity troponin T (hs-TnT) assays detect myocardial injury sooner, possibly improving throughput times for emergency department (ED) assessment of suspected acute myocardial infarction (AMI). This study evaluates the influence of hs-TnT implementation on ED length of stay (LOS), consultations and admissions, as well as ED revisits with cardiology admissions for patients undergoing testing for suspected AMI.

Methods: This control pre-post design analysis included patients evaluated using hs-TnT or conventional troponin T.
