Cumulative distribution of time to discharge from the emergency department before and after the introduction of high-sensitivity cardiac troponin T.

Relative distribution of coronary angiography findings before and after the introduction of high-sensitivity cardiac troponin T. Relative distribution of coronary angiography findings performed in acute chest pain patients before (Phase A) and after (Phase B) the introduction of a high-sensitivity cardiac troponin T assay.

Changes in rates of cardiac stress testing and coronary angiography. Bars represent rates of cardiac stress testing, coronary angiographies, and percutaneous coronary interventions before (Phase A) and after (Phase B) the clinical introduction of high-sensitivity cardiac troponin T. SPECT, single-photon emission computerized tomography; ARR, absolute risk reduction; RRR, relative risk reduction; ns, not significant.

Change in trends of duration of stay on the emergency department before and after the introduction of high-sensitivity cardiac troponin T. Scatter plot depicting the duration of stay on the emergency department for each patient with respect to months before (Phase A, grey) and after (Phase B, blue) the introduction of high-sensitivity cardiac troponin T. Interrupted time series analyses were used to analyse for trends during both phases and to compare for change in slopes.
