Laboratory professionals are now more than ever required to perform studies that provide evidence of the impact of testing on patient outcomes since the growth of laboratory medicine is reliant on its “value add” in the health-care landscape. In order to demonstrate the value for testing, we need to understand whether the test is worth of investment and to identify the impact of testing on management, care pathways and outcomes. However, in reality, to link the clinical laboratory information to value is challenging. Most laboratory tests are used for multiple purposes and in combination with other laboratory or medical tests in a complex care pathway. Impact of laboratory testing on patient outcomes is partial and variable since measured outcomes may be many steps beyond the performance of the test and affected by many other variables. So when the outcome information is missing, quantifying the value of the lab tests is difficult. The IFCC Task Force on Outcome Studies in Laboratory Medicine (TF-OSLM) was established in 2022. In this webinar, three members from the IFCC TF-OSLM will share the taskforce’s mandates and experience in identify existing peer reviewed, high quality publications that demonstrate the value of laboratory medicine in healthcare and developing a funded research program for investigators in hospitals located around the world to conduct new retrospective and prospective research with outcomes that assess the value of laboratory medicine in healthcare overall.
