In the patient-centered laboratory, it is no longer enough to identify, analyse and monitor errors, but it is now compelling to understand and manage the potential risks error associated with errors. In particular, a relatively high frequency of analytical errors has been documented for immunoassays with associated adverse clinical outcomes, sometimes resulting in grossly erroneous results 2.
The CCLM contribution to improvements in quality and patient safety. These discrepancies 2267 due to isso different tools used.
Ann Emerg Med ; Pre- and post-analytical phases While the frequency of laboratory errors varies greatly, depending on the study design and the specific steps of the total testing process TTP investigated, a series of papers published between and 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.
However, a major problem is the lack of kso defined Qls, particularly for extra-analytical phases. While the frequency 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 isl professionals to the pre- and post-analytical phases, which currently appear to be more vulnerable to errors than the analytical phase.
Course Syllabus Course Lesson. Open in a separate window. Depending on whether potential risks or actual risks are assessed, high priority risks could be related to pre-analytical and post-analytical steps, respectively.
Two main aspects contribute to this consideration. Two considerations may be brought oso explain this data: The list of Qls is available on line at www.
Patient safety and risk management in medical laboratories: theory and practical application
CLSI guidelines and ISO standards strongly advocate that the medical laboratory implement Risk 222367 as a way to assure quality in their testing processes. Reasons for proficiency testing failures in clinical chemistry and blood gas analysis: Errors in a stat laboratory: Alternately to this jso approach, the CLSI EPA2 documents suggests a top-down approach, fault tree analysis FTAwhich starts by assuming a main system failure and determines the root cause of this failure.
Thus, moving from a focus on human failures e. Several studies were in fact limited to risk identification and assessment 2837whist others reported the corrective measures without verifying their effectiveness in terms of RPN reduction National Academies Press Isk ; 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.
Quality Indicators in Laboratory Medicine: The authors identified five failures, all related to suitability of sample and corrective actions. Detection, identification and monitoring of errors through a set of harmonized, evidence-based and patient-centred QIs, are effective tools for risk assessment. From a risk management viewpoint, the great majority of laboratory errors have little direct impact on patient care but provide important learning opportunities.
Ann Intern Med ; The first application of risk management principles to laboratory medicine, excluding the manufacturing industry, could be attributed to the development of quality control plans. Click here if you are not yet a member Email address: In both studies, the pre-analytic phase had the highest error rate, the most frequent problems arising from mistakes in tube filling, inappropriate specimen containers, and requesting procedures.
Is the risk analysis 222367 that is recommended for implementation in laboratories. However, as demonstrated by Lao and colleagues 20there may be some differences in distribution of failures, and then in interventions prioritization, ixo on whether potential risks or actual risks are assessed. The physician and the laboratory. Therefore, the main message is the need to improve the quality of laboratory services, avoiding errors and improving patient safety, employing a global approach across the TTP, according to the seminal concept of the brain-to-brain loop Overall, data reported demonstrate that the initial and final steps of the TTP process, above all test requesting and reaction to laboratory results, are not only more error-prone than all the other steps, but are also the most important causes of potential adverse outcomes for patients.
Although errors 2236 generally attributed to failures of healthcare staff, most of them result from failure kso design safe processes.
Incorrect interpretation of diagnostic or laboratory tests in the end stages of the TTP loop was found to underlie a large percentage of errors in the ambulatory setting and in emergency departments. 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 222367 of a poor system design is to problems in communication, integration of services and lack of accountability for areas where one service ends and another begins.

The activity that measured the highest RPN was a post-post-analytical activity, i. Partners in reducing diagnostic error related to laboratory testing.
The reduction of RPN after three months from implementation of corrective actions showed their effectiveness summed to that of the entire risk management process, although FMEA remains a technique especially useful for evaluating a new process prior to its implementation 2267 not for process monitoring.
According to ISO In another study, approximately one-third of sub-acute care patients had laboratory tests microbiology tests in particularwhich were pending at discharge, but few of these cases were recorded in ido discharge forms This inspired a patient-centred evaluation ixo errors in laboratory testing and an increased lso 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.
The system also requires reporting the area inside or outside laboratorysource and detection system compliant, laboratory quality system, unknown of errors, in order to encourage participants to analyse the causes and responsibility of these errors Since there is no zero-risk activity, the ultimate goal of this process is to reduce the risk to an acceptable level for both patients and clinicians.
FRACAS is a tool by which failures are identified and analysed, so that corrective actions can be implemented How do I take this course? In fact, any error, regardless of its apparently trivial nature, might indicate weaknesses in policies and procedures that may not lead to adverse events in their particular context, but might cause the patient harm in slightly different circumstances The risk estimation, also defined risk assessment, is an essential oso of risk management process.
From patient safety perspective, all hazard situations in the laboratory should be analysed before harming patients. Any error might indicate weaknesses in policies and procedures that may not lead to adverse events in such particular context, but might cause patient harm in slightly different circumstances. Periodic participation in external quality assurance EQA programs is another example of risk management principles applied to medical laboratories Arch Intern Med ; 5: The brain-to-brain loop concept for laboratory testing 40 years 2367 its introduction.
A brief history of errors in laboratory medicine Initial studies, starting from the seminal paper by Belk and Sunderman in 4as well as other articles published before the s, focused only on the analytical phase and demonstrated high rates and severity of analytical errors.
