Evaluation of a cardiac troponin process flow at the chest pain center with the shortest turnaround time
BACKGROUND: Early diagnosis of myocardial infarction is crucial in chest pain management and cardiac troponin (cTn) test is an important step in it. Process improvement to shorten the test turnaround time (TAT) may improve patients’ outcomes. The cTn test at chest pain center (CPC) of Zhongshan Hosp...

description | BACKGROUND: Early diagnosis of myocardial infarction is crucial in chest pain management and cardiac troponin (cTn) test is an important step in it. Process improvement to shorten the test turnaround time (TAT) may improve patients’ outcomes. The cTn test at chest pain center (CPC) of Zhongshan Hospital had the shortest TAT ever reported, but its process flow was not fully evaluated. METHODS: We performed a stepwise evaluation of CPC cTn TAT and explored the potential factor that might cause delay. The performance of CPC cTn test was also compared with cTn test and human chorionic gonadotropin (HCG) test ordered from emergency department (ED). RESULTS: At least 95% of CPC cTn tests were completed in 60 min, while 62% in 30 min. The medians of monthly order‐to‐collect time, collect‐to‐received time, and received‐to‐result time were ~7 min, ~3 min, and ~13 min, respectively. The samples collected at the bedside had longer collect‐to‐received time than the ones collected at the blood draw site next to the laboratory. Compared to ED cTn test and ED HCG test, CPC cTn test took less time in each step. A combination of the sample type switch and the centrifugation time reduction contributed the most to the shortening of TAT, which was reflected in the received‐to‐result time. CONCLUSIONS: The current process flow of CPC cTn test satisfied the requirements of chest pain management, giving an example of how to implement process improvement for emergency medicine to shorten TAT of laboratory tests. |
