Diagnostic Errors and Laboratory Medicine ā€“ Causes and Strategies

Mistakes in a stat laboratory: In fact, over the past decades, a ten-fold reduction in the analytical error rate has been achieved thanks to improvements in the reliability and standardization of analytical techniques, reagents, and instrumentation. Thus, moving from a focus on human failures e. However, as demonstrated by several publications on laboratory-related errors 22 – 24the pre- and post-analytical steps are the most errors-prone phases, so that they cannot be ignored as a part of the efforts for improving quality and reducing adverse events.

In addition, according to this Technical Specification 15any clinical laboratory should employ processes for: Understand the risk analysis approach that is recommended for implementation in laboratories. Two considerations may be brought to explain this data: Failure in the ordering of appropriate laboratory test and the application of laboratory test results are major contributors to diagnostic errors, along with residual problems in test performances analytical errors Exploring the iceberg of errors in laboratory medicine.

Lab Advice on Risk Analysis – includes 223677 exam. QIs incorporated in laboratory quality management system can minimize the possibility of errors occurrence and, consequently, enhance patient safety.

Towards harmonization of quality indicators in laboratory medicine. Failure to follow-up test results for ambulatory patients: Projects aiming to improve quality and patient safety must therefore be based upon a total quality perspective, in particular the accreditation of clinical laboratory services according to the International Standard ISO Although errors are generally attributed to failures of healthcare staff, most of them result from failure to design safe processes. Izo 1 The journey towards a patient-centered view of errors in laboratory medicine.

The brain-to-brain loop concept for laboratory testing 40 years after its introduction. Patient safety 2237 risk management in medical laboratories: The physician and the laboratory.


Informative Guidance for medical devices Annex H. Qual Saf Health Care ; The concept of risk management, regularly used in aerospace and automotive industries since the s 10has been initially applied to medical laboratories by the in vitro diagnostic manufacturers, in which products and components are subjected to stringent risk assessments before 2267 marketed. Identification errors were noted too, 23267 the appropriateness of test request was not considered in the study design.

Quality Indicators in Laboratory Medicine: Laboratory staff should hence lower the actual failures to an acceptable level, but should be aware and ready to avoid potentially serious risks but less frequent that could be masked.

Am J Med ; RPN or risk code allows then to distinguishing high from low risk processes, so prioritizing interventions.

Am J Clin Pathol ; Clin Chem Lab Med ; How should a medical laboratory make use of a manufacturer’s reported Risk information? Although there are io few reports on active use of risk management tools applied to medical laboratories, the latest ones to be published not only focus on analytical steps 25but relate to the entire testing process 26 – This inspired a patient-centred evaluation of errors in laboratory testing and an increased concern to identify weaknesses and vulnerability in procedures and processes, so that corrective and preventive actions can be activated before any adverse event or patient harm may occur.

As an example, monoclonal proteins may affect many laboratory measurements, including glucose, bilirubin, C-reactive protein, creatinine and albumin.

This is one of the few studies in which the risk management process has been conducted in its all phases, from risk identification ixo risk control. Laboratory errors and risk management From a risk management viewpoint, the great majority of laboratory errors have little direct impact on patient care but provide important learning opportunities.

Pending laboratory tests and the hospital discharge summary in patients discharged to sub-acute care. During the past decade, after the publication of the Iao of Medicine IOM report, To Err Is Human 1patient safety has finally become the object of 2367 and public attention.


BMC Fam Pract ; 8: In addition, different approaches are used to defining goals and identifying risks. While the frequency of laboratory errors varies greatly, depending on the study ixo and steps of the total testing process TTP investigated, a series of papers published in the last two decades drew the attention of laboratory professionals to the pre- and post-analytical phases, which currently appear to be more vulnerable to errors than the analytical phase.

In addition, the analysis of root causes showed that failures are due to non-laboratory personnel, according to other studies available in literature 30 – 34thus emphasizing that errors are often the result of a poor system design leading to problems in communication, integration of services and lack of accountability for areas where one service ends and another begins.

Abstract While the isoo of laboratory errors varies greatly, depending on the study design and steps of the total testing process TTP investigated, a series of papers published in the last two decades drew the attention of laboratory professionals to the pre- and post-analytical phases, which currently appear to be more vulnerable to errors than the analytical phase.

Serafini and colleagues 27 chose to analyse the entire testing process of a specific test, the Factor V Leiden isl, since the high variability 2236 this test is responsible for wrong results with a consequent number of repetitions and incremental costs.

J Gen Intern Med ; However, although the state-of-the-art highlights that pre- and post-analytical phases are more vulnerable to errors, there is still evidence indicating that analytical quality remains a major issue.
