Pre-analytical errors: their impact and how to minimize them By: Nitin Kaushik By: Sol Green May 18, 2014 0 15035 The clinical laboratory plays an preanalytical errors in blood collection increasingly important role in the patient-centered approach to the delivery of pre analytical error definition healthcare services. Physicians rely on accurate laboratory test results for proper disease diagnosis and for guiding post analytical errors therapy; it is estimated that more than 70% of clinical decisions are based on information derived from laboratory test results.1 The process of blood testing, also known as

the “Total Testing Process,” begins and ends with the patient. It includes the entire process from ordering the test to interpretation of the test results by the clinician. The Total Testing Process can be subdivided into three stages: Pre-analytical: test request, patient and specimen identification, specimen collection, transport, accessioning and processing Analytical: specimen testing Post-analytical: reporting preanalytical errors in clinical laboratory ppt test results, interpretation, follow up, storage, retesting if needed. Additionally, the term “pre-pre-analytical phase” has been used for the initial part of the pre-analytical phase, focused on test selection and identification of test needed, and the term “post-post-analytical phase” has been used for the interpretation of results by the clinician.2 The numbers don’t lie: it’s a significant problem Clinical laboratory errors directly lead to increased healthcare costs and decreased patient satisfaction. A laboratory error is defined as any defect that occurs during the entire testing process, from ordering tests to reporting results, that in any way influences the quality of laboratory services.3 Any error during the laboratory testing process can affect patient care, including delay in reporting, unnecessary redraws, misdiagnosis, and improper treatment. Sometimes, these errors may even be fatal (e.g., acute hemolytic reaction after incompatible blood transfusion caused by an error in patient identification).3 It has been observed that diagnostic errors have led to the most prevalent type of malpractice claim in th

However, while it has been reported that the pre-analytical phase is error-prone, only recently has it been demonstrated that most errors occur in the ‘pre-pre-analytical phase’.
