Key result
Introduction of high-sensitivity cardiac troponin I assays reduced median time spent in the ED (3.85 h vs 4.35 h; P<0.001) and increased coronary angiography rates, without changing admission rates.
Why the study?
Does the introduction of high-sensitivity cardiac troponin I assays improve ED triage times and clinical outcomes in patients presenting with suspected ACS?
Observational (n=12,360)
No
Does the introduction of high-sensitivity cardiac troponin I assays improve ED triage times and clinical outcomes in patients presenting with suspected ACS?
Effect estimate: Difference (95% CI -0.59 to -0.43)
Absolute Event Rate: 3.85% vs 4.35%
p-value: p=<0.001
The introduction of high-sensitivity troponin I assays in the ED reduced patient wait times and increased angiography rates without altering overall admission or revascularization rates.

May shorten ED stays in suspected ACS; observational data leaves net benefit open.
Yip et al. (2014) conducted an observational in suspected acute coronary syndrome (ACS) (n=12,360). high-sensitivity cardiac troponin I (hscTn-I) assays vs. standard troponin assays (pre-changeover) was evaluated on Time spent in the ED (hours) (Difference, 95% CI -0.59 to -0.43, p=<0.001). Introduction of high-sensitivity cardiac troponin I assays reduced median time spent in the ED (3.85 h vs 4.35 h; P<0.001) and increased coronary angiography rates, without changing admission rates.
