Course Syllabus Course Lesson. 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 and not for process monitoring.
Quality in healthcare appears as strictly connected to risk management principles. Factitious biochemical measurements resulting from hematologic conditions. Qual Saf Health Care ; Identification errors were noted too, although the appropriateness of test request was not considered in the study design.
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. The frequency of this type of error is variable and probably underreported Since many qualitative and semi-quantitative scales for specific healthcare field e.
The CCLM contribution to improvements in quality and patient safety. 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. Failure to inform patients of clinically significant abnormal test results or to record the delivery of relevant information is relatively common, occurring in 1 out of isk 14 tests; for example, patients not being informed of a total cholesterol value of 8.
Clin Chem ; Thus, moving from a focus on human failures e. Partners in reducing diagnostic error related to laboratory testing. In the late nineties, a body of evidence was accumulated which documented: In addition, most of the many different terms used in the literature to define errors in laboratory medicine e.
The risk estimation, also defined risk assessment, is an essential step of risk management process. Two considerations may be brought to explain this data: Oso reporting, classification and grading of quality failures in the medical laboratory.
For each failure that can be identified it is possible to obtain a risk priority number RPN or a risk code respectively, on whether semi-quantitative or qualitative scale is used. In fact, any error, regardless of its apparently trivial nature, might 222367 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 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.
CEN ISO/TS 22367
Although it has been shown that: Reasons for proficiency testing failures in clinical chemistry and blood gas analysis: 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.
J Gen Intern Med ; Ann Clin Biochem ; Quality Indicators in Laboratory Medicine: Patient safety and risk management in medical laboratories: QIs incorporated in laboratory quality management system can minimize the possibility of errors occurrence and, consequently, enhance patient safety.
It is hence described as a global process, which should anticipate what may go wrong non-conformities, errors and accidentsthus assessing plausibility of errors occurrence along with consequences they cause and implementing strategies to reduce the risk of potential harm.
Carraro P, Plebani M. Harmonization of quality indicators in laboratory medicine. Although errors are generally attributed to failures of healthcare staff, most of them result from failure to design safe processes.
In addition, advances in information technology, quality control and quality assurance methods have made a valuable contribution to error reduction. I the error rate in medical laboratories is very low one error identified every —1, events, meaning every —2, patients or —8, laboratory results 2 ; and II the majority of these error rarely become adverse events 8patient safety should be considered the goal of laboratory services and its principles must be systematically applied in a well-structured manner.
ISO/DIS – Medical laboratories — Application of risk management to medical laboratories
Patient safety is defined as the absence of avoidable patient harm due to adverse events occurring in any process of medical attention. On the basis of this assumption, full implementation of risk management and quality management systems should not be regarded as separate activities, but should be integrated within everyday practice of all laboratory professionals. Failure in ido 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 This model is divided into process and outcome measures, mainly based on measures of the pre- intra-and post-analytical procedures and processes, and has been revised in a Consensus Conference organized to establish a list of Qls that should be evidence-based, feasible for most laboratories around the world and actionable According to ISO In addition, according to this Technical Specification 15any clinical laboratory should employ processes for: FRACAS is a tool by which failures are identified kso analysed, so that corrective actions can be implemented Am J Clin Pathol ; BMJ Qual Saf ; The risk should be continuously monitored for verifying that the control measures have been effective, but also for detecting other errors so far overlooked, so finally ensuring patient safety.
The organization within which the laboratory operates and the available resources are other factors to be considered when choosing approaches.
