Background: Turnaround time (TAT) is a major quality control indicator and can be defined differently depending on the starting point in the examination process. To determine effective TAT management plan, we investigated the status of TAT management in clinical laboratories in Korea.
Methods: A questionnaire was developed using Google web pages and a questionnaire survey was conducted at 30 clinical laboratories in laboratory medicine from September 1 to 11 in 2018. Questions were developed regarding management time, starting point standards, management goals, most problematic stages of delayed TAT, clinical measures, and shortening barriers for investigation.
Results: All clinical laboratories requested to undertake the survey completed the questionnaire (response rate 100%, 30/30) and answered that they were setting and managing TAT for all tests. Many laboratories (33%) set the TAT starting point as the reception stage, prior to commencing centrifugation. Of the surveyed laboratories, 37% achieved a TAT of 120 min or more for general tests, 27% met the TAT of 90 min for pre-clinic tests, and 77% met the TAT of 60 min for completion of stat tests. Most laboratories (67%) reported that the most delayed stage was pre-analysis, and 50% reported that the greatest obstacle to shortening TAT was the ratio of stat and pre-clinic tests to general tests.
Conclusions: The laboratories participating in this survey set a TAT based on various criteria and were performing management for TAT improvement. The results of this study can be used as basic data to guide efficient TAT management.
