Abstract

We assessed the efficiency of point-of-care (POC) tests in the emergency department (ED) by comparing them with the international standard. We recorded the turnaround times (TATs) for processing laboratory biomarkers to assess laboratory efficiency from 17 EDs in national/regional hospitals. We also compared patient components between national and regional hospitals. Although the 17 enrolled hospitals expanded their EDs, they contained only five POC machines among them. The P50 (P25, P75 ) of the TATs for POC tests was 47 min (39, 55.5 min) for cardiac troponin T, which was much longer than the international standard (30 min). The TATs of other cardiac biomarkers were also longer than 30 min. The low efficiency of TATs for POC tests was a common feature in both regional and national hospitals ( p > 0.05). Myocardial infarction was diagnosed in 61% of investigated ED patients who visited national hospitals, which is more frequently than those diagnosed at regional hospitals (46%, p < 0.05). Chronic heart failure was less frequent at national hospitals (28%) than at regional hospitals (41%, p < 0.05). The patient distribution in this study indicates that patients have the tendency to choose hospitals when they are affected with chest pain. However, the POC panel is rarely used in the ED, which delayed the TAT level and affected laboratory efficiency. This finding indicates a severe problem in the administrative management of EDs. This issue should be addressed in the next version of the medical reform policy.
