Point of Care Troponin T Test Reduces Acute Coronary Syndrome Diagnostic Delays

Forth Valley Royal Hospital has been able to reduce the length of stays and ward admissions for patients presenting with chest pain, as well as ensuring rapid referral for patients with positive findings, through the introduction of a Chest Pain Assessment Unit (CPAU) that offers streamlined patient care and rapid access to diagnostic testing, including Troponin T testing using the Roche point of care (POC) cardiac marker system, Cobas® h 232.

“Prior to opening the CPAU patients at low risk of Acute Coronary Syndrome (ACS) were spending a long time in hospital unnecessarily, often overnight, while ACS was ruled out, ” explains Nurse Consultant – Acute Medicine, Sharon Oswald. “To obtain real-time results that enable rapid decisions to be made, we introduced the Roche Cobas h 232 system for point of care Troponin T testing. The cobas h 232 has had a huge impact on the service. Before we introduced it, Troponin T tests were batched and performed four times per day in the laboratory. There were sometimes delays in getting the bloods to the laboratory and then in getting results back. Now, with the Cobas h 232 systems, we are able to obtain results in real time, which allows faster decision making.”

“The Cobas h 232 system is very sensitive,” Sharon adds. “A six month comparative evaluation demonstrated that we were getting comparable results to the laboratory method. We still send positives to the laboratory for confirmation but negative results do not require further confirmation This means that ACS is excluded more quickly, allowing earlier discharge. Patients that require further investigation or care can be referred immediately or given a planned return appointment.”
