简要总结
In a randomized, controlled clinical trial, point-of care testing at the bedside using the cardiac biomarker troponin I in ED patients with possible ACS will be compared to traditional testing of this assay for myocardial necrosis obtained in the central laboratory. Our hypothesis: point-of-care testing for troponin I will decrease the time for disposition of patients with possible ACS in the emergency setting and decrease the time required for administering appropriate therapies for these patients.
详细描述
Cardiac troponin I is routinely used in the emergency department as a risk stratification tool for detecting myocardial necrosis in patients with possible acute coronary syndrome. It is our hypothesis that having bedside, point-of-care testing for TnI in the ED will decrease time needed to disposition patients to home from the ED or send to the cardiac catheterization laboratory or intensive care setting. Similarly, having point-of-care testing in the ED should decrease the time required to deliver anti-platelet drugs such as aspirin and glycoprotein IIb/IIIa inhibitors and anti-thrombin agents such as heparin to high risk patients found to have a positive TnI test. This will be evaluated in a randomized, controlled clinical trial of 2000 patients. Half will have the test performed in the ED at the bedside (point-of-care) while the other half will receive the usual lab results obtained from the central lab (typically requiring 1.5-2 hours to return).

结局指标
主要结局
Time to disposition from the ED
时间窗: The time from blood draw to initiation of therapy or to disposition
The primary hypotheses are that i) POC testing using the i-STAT system reduces the time to disposition and discharge for low-risk patients being discharged directly from the ED, and ii) POC testing using the i-STAT system reduces the time to therapy compared to laboratory testing for the subset of patients requiring anti-thrombotic therapies such as heparin/LMW heparin or anti-platelet agents such as GPIIb/IIIa inhibitors or clopidogrel or PCI. These groups of patients (those with new ST-depression, recurrent pain, positive troponin, diabetes, age \>65 years, or failed ASA and those discharged without a diagnosis associated with ischemic chest pain) will be extracted from the entire sample. The time from blood draw to initiation of therapy or to disposition and discharge will be computed and compared between the group with POC testing and the group with laboratory testing.
次要结局
- Time to departure(time of discharge to home or to the time of transfer to an inpatient setting)
