CSRS Implementation - A Pilot Study

The intervention is knowledge translation of the CSRS practice recommendations; the application of the practice recommendations will occur during the patient's ED visit and patients who are eligible for 15-day cardiac rhythm monitoring will have Holter monitor applied at the time of ED discharge. For the secondary objective to validate the accuracy of the ultra-low risk criteria of CSRS and assess for potential improvements in the practice recommendations and the prediction models we will request verbal consent during the index ED visit for addition of cardiac biomarker measurements \[troponin and NT-proBNP\] for patients who did not have such measurements performed as part of routine clinical care, and a 30-day telephone follow-up for serious outcome assessment. Patients who do not consent will be excluded from these portions of the study but included in the health resource utilization and generic patient safety outcome assessment objectives.
