  • Title: Quality in laboratory medicine: 50years on.
    Author: Plebani M.
    Journal: Clin Biochem; 2017 Feb; 50(3):101-104. PubMed ID: 27760306.
    Abstract:
    The last 50years have seen substantial changes in the landscape of laboratory medicine: its role in modern medicine is in evolution and the quality of laboratory services is changing. The need to control and improve quality in clinical laboratories has grown hand in hand with the growth in technological developments leading to an impressive reduction of analytical errors over time. An essential cause of this impressive improvement has been the introduction and monitoring of quality indicators (QIs) such as the analytical performance specifications (in particular bias and imprecision) based on well-established goals. The evolving landscape of quality and errors in clinical laboratories moved first from analytical errors to all errors performed within the laboratory walls, subsequently to errors in laboratory medicine (including errors in test requesting and result interpretation), and finally, to a focus on errors more frequently associated with adverse events (laboratory-associated errors). After decades in which clinical laboratories have focused on monitoring and improving internal indicators of analytical quality, efficiency and productivity, it is time to shift toward indicators of total quality, clinical effectiveness and patient outcomes.
