Abstract

Objective: Radio-contrast abdomino-pelvic computed tomography (APCT) is considered the gold standard diagnostic tool for an acute abdomen in the emergency department. On the other hand, APCT has a risk of contrast-induced nephropathy. Emergency physicians evaluate the creatinine (Cr) level prior to taking a APCT for the above reason but it takes time to evaluation the serum Cr level. This study hypothesized that Cr measured by a point-of-care test (POCT) can shorten the time to making clinically important decisions for patients with an acute abdomen.
Method: This prospective randomized study was conducted between March 2017 and October 2017. The subjects were divided into two groups (Cr measured by laboratory vs. Cr measured by POCT). To analyze the clinical acceptability for creatinine, agreement was demonstrated graphically by Bland-Altman plots. This study compared the time to make a clinically important decision by physicians and the length of stay at the emergency department in both groups.
Results: A total of 76 patients were eligible for the study, 38 patients were assigned to each group. There was no statistically significant difference in the time to the first medical examination (P=0.222) and emergency department stay time (P=0.802). On the other hand, the time to recognition of the Cr level (P<0.001), time to performing APCT (P<0.001), time to decision making (P<0.001), and time to initiation of treatment (P<0.001) were shortened significantly in the point-of-care creatinine group.
Conclusion: In this study, the POCT for creatinine can allow rapid decision making by shortening the time to performing the radio-contrast APCT than the laboratory for patients with an acute abdomen.
