Abstract
Today, medical laboratories invest a great deal of effort in understanding the root cause of errors (both systematic and individual failures), in developing interventions to minimize those failures and in assessing the effect of implementation of error reduction processes.The Clinical Laboratory Improvement Amendments (CLIA) requires that a clinical laboratory’s quality assurance program include evaluation of each of the steps of the total testing process (TTP). In response to this requirement, laboratories have identified indicators that measure their performance in key functions related to patient care and satisfaction. Performance on these indicators is to be reported periodically to the organization, with follow-up actions to be taken to design the processes well and improve the outcome. Quality indicator (QI) is quality tool enabling us to quantify the laboratory’s performance by selecting a certain comparative criterion, its aim to assess the performance and initiate corrective measures to ensure continual improvement. Assessment of the quality of laboratory services using QIs requires a systematic, transparent, and consistent approach to collection and analysis of data, QIs should be designed in a way to enable rapid detection of deviations in proper function of the processes, simple to implement, updated periodically and adapted to changes occurring in the processes. When the program identifies opportunities for improvement within the system, the laboratory management shall take appropriate steps to address them.
