Stat labs are for immediate testing and treatment of critically injured patients
Stat labs, derived from the Latin word "statim," meaning immediately, are an integral part of hospitals, providing rapid testing and evaluation for critically injured patients. The primary purpose of stat labs is to facilitate immediate testing and treatment for patients in life-threatening or critical situations.
The urgency of stat labs is evident in their name, indicating the need for immediate action. They are particularly crucial in trauma centres, where timely evaluation and treatment can mean the difference between life and death. For example, a STAT ECHO order could indicate ongoing CPR or decompensating congenital heart disease, requiring immediate medical attention.
Stat labs are characterised by their swift turnaround times, ensuring that specimens are processed and evaluated promptly. This rapid processing is achieved through various means, including dedicated stat lab staff, limited test menus, and, increasingly, laboratory automation systems. These systems standardise the testing process, from specimen collection to result reporting, enhancing efficiency.
The tests conducted in stat labs are typically limited to those that can be performed quickly and are essential for immediate patient care. Blood gases, CBC (complete blood count), coagulation testing, and limited chemistries are examples of tests commonly performed in stat labs. By focusing on these critical and time-sensitive tests, stat labs play a pivotal role in the initial assessment and stabilisation of patients.
The importance of stat labs in trauma centres is underscored by the requirement for a dedicated stat lab to obtain the PARC (Primary Adult Resource Centre) designation. This highlights the critical role of stat labs in providing timely and specialised care for critically injured patients. Furthermore, the emergence of outlying surgical centres and the emphasis on shorter hospital stays have further accentuated the need for efficient STAT testing capabilities.

Specimen collection and result delivery impact turnaround times
A stat lab in a hospital is a dedicated facility that provides rapid specimen analysis and results for critically injured patients. The timely provision of results enables swift evaluation and treatment. Specimen collection and result delivery are crucial components of the turnaround time (TAT) in stat labs, which directly impacts patient outcomes.
The TAT in clinical diagnostics is the duration between initiating a process and fulfilling a request. In the context of stat labs, the TAT is influenced by various pre-analytical, analytical, and post-analytical factors. Specimen collection is a critical pre-analytical factor that can significantly impact the overall TAT. This phase encompasses test requests, patient and specimen identification, collection, transportation, accessioning, and processing. Inefficiencies or delays in any of these steps can hinder the overall TAT.
To optimize specimen collection and minimize TAT, stat labs should employ efficient workflows and modern technologies. Utilizing robotic specimen transport systems, such as the Tempus600 pneumatic tube system, automates the movement of samples between departments, eliminating manual transport and reducing potential delays. Additionally, implementing laboratory information management systems (LIMS) can streamline processes by automatically triggering the next step in the workflow as soon as a sample is processed. This real-time automation is crucial in emergency settings, expediting decision-making and improving patient outcomes.
Result delivery is another critical aspect of TAT in stat labs. Efficient communication between different hospital departments is essential for maintaining short turnaround times. Effective collaboration allows for better prioritization of urgent samples, streamlined workflows, and quick resolution of issues during testing phases. Conversely, communication breakdowns can lead to bottlenecks and extended delays, negatively impacting efficiency and patient satisfaction.
The impact of specimen collection and result delivery on TAT in stat labs is significant. By optimizing these processes through efficient workflows, automation, and effective inter-departmental communication, stat labs can provide rapid results, enabling timely treatment decisions and improved patient care.

Stat testing is a priority for patients requiring a high level of care
STAT (short turn-around time) testing is an important aspect of providing high-quality care in hospitals. It involves the rapid evaluation and treatment of patients, particularly those who are critically injured or facing life-threatening situations. STAT testing ensures that patients receive timely and accurate diagnoses, enabling doctors to make quick and informed decisions about their treatment.
STAT testing is often required in emergency departments, intensive care units, and surgical suites, where immediate results are crucial for patient management. For example, in the case of a patient experiencing CPR or decompensating congenital heart disease, a STAT echo can be performed to rule out tamponade or PE. Similarly, in the event of suspected sepsis, stroke, or myocardial infarction, accelerated protocols for biochemical marker evaluation are utilised. STAT testing is also valuable when ordering multiple lab tests to avoid poking the patient multiple times.
The development of laboratory automation systems has revolutionised STAT testing. These systems handle the entire testing process, from specimen collection to result reporting, ensuring all specimens are treated identically and streamlining the testing process. Laboratory automation has improved the turnaround time for routine tests, bringing them closer to the urgency of STAT tests. Additionally, Point of Care Testing (POCT) and Near Patient Testing (NPT) have emerged as solutions to the need for shorter turn-around times, bringing testing equipment closer to the patient's location.
To further enhance STAT testing capabilities, hospitals are focusing on connectivity and technical support. The success of near-patient analytical systems relies on strong partnerships between vendors, IT teams, and laboratory staff. By prioritising connectivity and data management, hospitals can ensure that test results are reviewed promptly and accurately, regardless of where the data is generated. This two-tiered structure of STAT "laboratory" testing, encompassing both general lab work and Near Patient testing, improves efficiency and patient management.
Overall, STAT testing is a critical component of high-level patient care in hospitals. It requires efficient processes, dedicated staff, and advanced technology to provide rapid and accurate results. By prioritising STAT testing, hospitals can deliver timely diagnoses and treatment, improving patient outcomes and satisfaction.

Overuse of stat orders can be reduced with individual feedback
STAT, an abbreviation of the Latin word "statim," means "immediately, without delay". The overuse of inpatient stat laboratory orders is a significant problem in the modern healthcare system. This issue is particularly prevalent among Medicine and General Surgery residents, with the median proportion of stat orders out of total laboratory orders reaching 41.6% for nontrainee providers, 38.7% for Medicine residents, and a staggering 80.2% for General Surgery residents.
To address this concern, a study was conducted at an urban teaching hospital, where Medicine and General Surgery residents were educated about appropriate stat ordering practices. Following this intervention, individual feedback was provided to providers with the highest utilization rates of stat laboratory orders. The feedback was given by their direct supervisors over a period of five months.
The results of the study demonstrated a notable decrease in the proportion of stat laboratory orders among those who received feedback. Specifically, there was a reduction of 15.7% in the frequency of stat orders among Medicine and General Surgery residents. On the other hand, providers who were high utilizers but did not receive feedback showed only a minor decrease of 4.5%.
This study highlights the effectiveness of targeted individual feedback in reducing the overuse of stat orders. By providing direct feedback to high utilizers, hospitals can curb the unnecessary use of stat laboratory orders, improving patient care and optimizing resources.
Furthermore, the implementation of laboratory automation systems can also help address the overuse of stat orders. These systems standardize the testing process, ensuring that all specimens are treated with equal urgency. By "levelling the playing field," hospitals can improve the turnaround time for routine tests, reducing the perceived need for frequent stat orders.
