Identifying and Reducing Errors in Point-of-Care Testing

Point-of-care testing (POCT) refers to diagnostic testing performed outside of the central laboratory, near to the patient and often at the patient bedside. This testing is generally performed by clinical staff who are not laboratory trained and, as such, often do not appreciate the importance of quality assurance (QA) activities aimed at ensuring the quality of testing performed. Within hospital environments, it is typically the central laboratory that oversees POCT and that ensures QA practices are in-place. Audits for compliance of POCT users with policies and procedures in place are key to informing quality improvement initiatives. Here, audit and follow-up data and the results from three quality improvement initiatives are discussed. These examples demonstrate where QA audit practices led to a reduction in POCT errors and improved the quality of result interpretation.
