Key result
Point-of-care troponin testing reduced emergency department length of stay by 48 minutes (95% CI 12-84; P=0.063) and increased the proportion of patients discharged within 8 hours by 10% (P=0.007).

Mean Difference: 48 (95% CI 12–84)
p-value: p=0.063
Point-of-care troponin testing significantly increases the proportion of patients with possible ACS discharged from the emergency department within 8 hours compared to central laboratory testing.
Loten et al. (2010) conducted an RCT in Possible acute coronary syndromes (ACS). Point-of-care (POC) cardiac troponin I testing vs. Central laboratory testing was evaluated on Length of stay from patient arrival to physical departure from the ED (MD 48 minutes savings, 95% CI 12 to 84, p=0.063). Point-of-care troponin testing reduced emergency department length of stay by 48 minutes (95% CI 12-84; P=0.063) and increased the proportion of patients discharged within 8 hours by 10% (P=0.007).
