The purpose of this Cumitech is to provide clinical microbiologists with strategies to define, detect, describe, categorize, and prevent CML-associated errors.  The judgmental, intricate, and demanding nature of the procedures preformed in a CM laboratory and the critical results of stains, cultures, and antimicrobial susceptibility testing can lend themselves to errors and can lead to adverse outcomes.  By being proactive participants, by establishing measurable standards of quality, and by assigning accountability, laboratory personnel have the opportunity to decrease errors that can cause harm to patients.
