In order to achieve the highest quality of patient care, laboratory must define reasonable STAT (Emergency) turnaround times for all testing. Turn around Time (TAT) is used to determine a laboratory’s efficiency in producing its specimen results. Strictly adhered to in all laboratories, it is one of the key performance indicators measured.
TAT is the time taken for a sample to be analyzed refers to the time a sample is collected in the laboratory until the time of reporting results. Faster TAT is universally seen as desirable, as the timely and rapidly a test is performed, the more efficient and effective will be the treatment. This in turn saves time and money for the patient, as well as the hospital.
It can be a useful tool in determining if there is a problem on a specific shift with specific tests. Turn-Around-Times are monitored in the lab by way of any complaints or issues that might come up about the timeliness of reporting results. Any issue that is brought up is investigated and documented in Laboratory Performance Improvement reports.
The average turn-around-time from order of STAT( Emergency) laboratory tests to draw is 30 minutes. This is monitored each month by pulling stat TAT reports and specific tests ordered in the Emergency Room.
The following TAT is from time of sample collection in lab to delivery of results.
- for all components of the CBC, the general turnaround time is 30 minutes.
- for all components of a urinalysis, the general turnaround time is 30 minutes.
- for all coagulation tests, the general turnaround time is 30-45 minutes.
- for compatibility testing, the general turnaround time is 45 minutes to 1 hour.
- for serology testing, the general turnaround time is 60 minutes.
- for general chemistry tests, the general turnaround time is 60 minutes.
- For CSF cell count and chemistry, the general turnaround time is 90 minutes.
- For CSF gram stain, the general turnaround time is 90 minutes.
- for immunoassay chemistry tests the general turnaround time is 1 hour to 1 hour, 15 minutes.
- All Defined Laboratory STAT turnaround times are reasonable, but always subject to problems or workloads at the time. If testing is ordered as stat, results are reported as soon as possible. Most Emergency Room (ER’s) with many tests ordered is reported within 1 hour, depending on orders and circumstances.
Laboratory Turn-Around times for STAT (Emergency) testing are monitored on a continual basis by the Laboratory Administration. This is monitored by way of complaints or issues that come up during testing. Any issues during time frame are documented in Laboratory Performance Improvement. The time is pulled from the computer and monitored on a monthly basis. Also percentage acceptable times are calculated and monitored on certain tests ordered in the Emergency Room. The goal is >90% acceptable on time from order to draw and from receipt to verify.
