Brief summary
As part of the planned implementation of a new clinical pathway using hs-cTnI, the investigators will measure patient outcomes and clinical processes in a real-world scenario throughout an integrated health system across 9 emergency departments (ED).
Detailed description
This is a pragmatic, implementation study testing the implications of a real-world execution of a rapid evaluation pathway for suspected ACS using the Beckman hs-cTnI assay. As the new protocol is executed across 9 EDs within an integrated health system, the investigators will study its effects on patient and system-level metrics. A modified stepped wedge design will be utilized that allows comparison of the RACE-IT pathway with standard of care management
Interventions
This care pathway includes the evaluation of suspected acute coronary syndrome with high-sensitivity troponin I testing and further prognostication as needed with a modified HEART score
Standard of care protocol that uses the 99th percentile troponin values for evaluation of suspected acute coronary syndrome and further prognostication using the HEART score

Stepped-Wedge Cluster Randomized
Eligibility
Inclusion criteria
* Patients ≥18 years old presenting to the ED for whom a treating clinician suspects ACS and orders a baseline ECG and cardiac troponin.
Exclusion criteria
1. ST-segment Myocardial Infarction (STEMI) leading to immediate reperfusion therapy 2. Any ED-drawn hs-cTnI value \> 99th percentile (18 ng/L) 3. Clear traumatic cause for symptoms (e.g., direct chest wall trauma, motor vehicle accident) 4. A transfer from another facility 5. Primary residence outside the state of Michigan 6. Previous inclusion in the study 7. Enrolled in hospice
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safe ED discharge | 30 days after initial presentation | Proportion of patients with safe discharges home from the ED, defined as being without death or acute myocardial infarction within 30-days |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Length of hospital stay | From date and time of start of emergency department encounter until date and time of end of ED or hospital encounter (whichever is latest), assessed up to 7 days. | Length of time from initial presentation to the Emergency Department until final discharge from the Emergency Department or Observation Unit |
| Number of participants with death or acute myocardial infarction | 30-day and through 1 year | Death or presence of acute myocardial infarction determined by adjudication panel |
| Composite number of cardiology resources utilized | 30-days | Cardiology resources are inclusive of completed orders for cardiac stress tests, cardiology consultation, coronary computed tomography, coronary angiography, and percutaneous coronary intervention |
| Hospital payments received | 30-days | The total hospital payments received for the initial ED visit and any subsequent hospitalizations and procedures that are cardiology related over 30-days from the initial encounter. |
| Number of participants with revascularization or rehospitalization for cardiovascular disease | 30-days | revascularization includes percutaneous coronary interventions and rehospitalization is inclusive of any such event for acute heart failure, acute myocardial infarction, or arrhythmia |
Other
| Measure | Time frame | Description |
|---|---|---|
| Pre-specified sub-group analyses of the primary outcome | 30 days | We will explore analysis assessing gender-specific cut-points for hs-cTnI associated with safe discharge |
