ToTAT is the abbreviation for Total-Turn-Around-Time.
Traditionally most hospitals are working with the concept of TAT (Turn-Around-Time), when measuring their efficiency in processing their blood samples.
Unfortunately, when using TAT as a measurement for the process time of the blood samples, many focuses only on the process time of the blood samples - from when the sample arrives in the laboratory and until the result is available. As Lab equipment has developed, the process of analyzing blood samples has become faster with the introduction of automated tracks and analysis equipment. But it has reached a point where the improvements in analytical time is with very marginal improvements.
ToTAT on the other hand, is a measuring standard that encompass the entire process cycle of the blood samples, commencing when the blood sample is either ordered or drawn from the patient. The time scale revealed when implementing ToTAT as the standard of measuring the process time offers a completely different perspective on process efficiency.
Many hospitals around the world operates with a target time of less than one hour. This means that an answer or a result of a particular blood sample analysis should be provided within one hour. For a large portion of hospitals though, this is implemented for STAT-samples only.
Depending on the type of blood samples (e.g. plasma or serum), the type of analysis and the lab equipment available to the particular laboratory, the process time in the laboratory could span from 25 minutes to 50 minutes. The effect of which enables the laboratory - under ideal conditions - to provide the answer in less than an hour. One of the issues here is that more often than not, blood samples arrive to the laboratory in bulk. Hence increasing the process time of the blood samples due to the handling and in-lab-waiting-time, and potentially stretching the capacity of the laboratory.
Furthermore, the TAT gives no indication of "patient-waiting-time" or ToTAT, as there are none or little focus on the time it takes to get the sample from the patient to the laboratory. In short, this means that a laboratory that provides a TAT under an hour (which when isolated - looks good) might have a ToTAT of 2-3 hours, which is a long process/waiting time that no longer is necessary.
Implementing ToTAT as the standard measurement, will reveal the key area to attend to is more often than not, the routines of bringing the blood samples from the patient to the laboratory.
To solve the issue of bringing blood samples from the patient to the laboratory in the fastest and safest possible way while securing excellent potential for test results, economics, patient and staff satisfaction, Timedico A/S has developed and offers the Tempus600 Solutions via Tempus600 and Tempus600 Vita.
By implementing the Tempus600 system, ToTAT can be reduced to an average of just 30 minutes - from the blood sample has been drawn until the result is ready. This applies not only to STAT samples but to all samples. In fact, there is no longer STAT sample issues, as all samples are sent directly and individually from the ward to the laboratory, where it can be connected to Lab automation. Using Tempus600 as your system to send samples from the different department to the laboratory, not only provides you with a second to none ToTAT, the system is also able to send the samples according to FIFO (First in, First out). Lab capacity will not be stretched as samples do not appear in bulk but in a steady flow without any manual handling ensuring sample safety and speedy process time, from the patient to the result.
