Point of Care Testing—Current and Emerging Quality Perspectives
نویسنده
چکیده
The volume and repertoire of point-of-care testing (POCT) is increasing rapidly, and it is now used in a variety of settings, including patient self-testing. Point-of-care testing offers the significant advantage of rapidly available test results, which have the potential to expedite clinical decision making and improve patient outcomes. Modification of traditional patient care pathways may be required to attain the maximum clinical benefit from POCT. Although POCT simplifies the testing process, it may be more prone to error than conventional laboratory testing. Operator-related error has emerged as a significant risk factor. Efforts to minimize POCT-related quality errors should focus on better and more robust instrument design with increased automation, improved training, and assessment of POCToperators and an enhanced regulatory and governance framework. A key quality measure is the impact of POCT on clinical outcomes, but this generally has been less well documented. Evidence on the effect of self-monitoring of blood glucose in diabetes and selfInternational Normalized Ratio testing for patients on long-term anticoagulant therapy in improving clinical outcomes measures highlight the potential for POCT to enhance patient care.

The existing health care systems focus on treating diseases rather than preventing them. Patients are generally not tested unless physiological symptoms are appeared. When they do get tested, the results often take several days and can be inconclusive if the disease is at an early stage. In order to facilitate the diagnostics process and make tests more readily available for patients, the conce...
