Key result
Point-of-care hs-cTnI testing linked to ~43 minutes shorter ED length of stay versus laboratory testing.
Why the study?
The study was conducted to compare actual ED length of stay using laboratory-based hs-cTnI testing with the potential length of stay that could result from using point-of-care hs-cTnI tests.
Does point-of-care high-sensitivity cardiac troponin testing reduce emergency department length of stay compared to laboratory-based testing in patients discharged after a single baseline test?

Mean Difference: 43 (95% CI 40–46)
Absolute Event Rate: 157% vs 195%
Point-of-care high-sensitivity cardiac troponin testing has the potential to reduce emergency department length of stay by an average of 43 minutes for patients discharged after a single test.

POC hs-cTnI may shorten ED LOS in discharged patients; leaves open its impact on safety and workflow in larger studies.
Meek et al. (2025) conducted an observational in Emergency department patients requiring hs-cTnI testing (n=152). Point-of-care (POC) hs-cTnI testing vs. Laboratory-based hs-cTnI testing was evaluated on Emergency department length of stay (LOS) (MD 43, 95% CI 40-46). Point-of-care hs-cTnI testing could potentially reduce emergency department length of stay by a mean of 43 minutes (95% CI: 40-46) compared to laboratory-based testing.
