Defining a roadmap for harmonizing quality indicators in Laboratory Medicine: a consensus statement on behalf of the IFCC Working Group "Laboratory Error and Patient Safety" and EFLM Task and Finish Group "Performance specifications for the extra-analytical phases".

The improving quality of laboratory testing requires a deep understanding of the many vulnerable steps involved in the total examination process (TEP), along with the identification of a hierarchy of risks and challenges that need to be addressed. From this perspective, the Working Group "Laboratory Errors and Patient Safety" (WG-LEPS) of International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is focusing its activity on implementation of an efficient tool for obtaining meaningful information on the risk of errors developing throughout the TEP, and for establishing reliable information about error frequencies and their distribution. More recently, the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) has created the Task and Finish Group "Performance specifications for the extra-analytical phases" (TFG-PSEP) for defining performance specifications for extra-analytical phases. Both the IFCC and EFLM groups are working to provide laboratories with a system to evaluate their performances and recognize the critical aspects where improvement actions are needed. A Consensus Conference was organized in Padova, Italy, in 2016 in order to bring together all the experts and interested parties to achieve a consensus for effective harmonization of quality indicators (QIs). A general agreement was achieved and the main outcomes have been the release of a new version of model of quality indicators (MQI), the approval of a criterion for establishing performance specifications and the definition of the type of information that should be provided within the report to the clinical laboratories participating to the QIs project.

Recomendaciones para el diseño e implementación de un programa de aseguramiento de la calidad de la fase preanalítica / Recommendations for the design and implementation of a Pre-analytical Phase Quality Assurance Program

El aseguramiento de la calidad de la fase preanalítica se orienta hacia 2 aspectos clave: la gestión de los errores preanalíticos desde la perspectiva de la seguridad del paciente, y la mejora y armonización de los procedimientos, basada en la aplicación de normativa además de recomendaciones profesionales. Al igual que el resto de las fases, debe incluir un programa interno de aseguramiento y la participación en programas de intercomparación entre laboratorios. El control de calidad interno debe basarse fundamentalmente en la identificación de riesgos, detección sistemática de errores y establecimiento de indicadores. La selección de los indicadores priorizando el impacto en el paciente, la forma de detectar y registrar los errores de forma sistemática y fácilmente explotable, así como las variables utilizadas en su cálculo, son aspectos importantes para medir la eficacia de las acciones de mejora y permitir la comparabilidad entre laboratorios. En este sentido, los programas externos de la calidad de la fase preanalítica basados en la comparación de indicadores, son una herramienta útil para el diseño e implantación de un programa de aseguramiento de la calidad. Este documento pretende servir de apoyo para que cada laboratorio seleccione, implante y evalúe sus propios indicadores, de acuerdo a las características individuales de sus procedimientos preanalíticos, pero sin perder de vista la armonización entre laboratorios

The quality assurance of the pre-analytical phase is oriented towards two key aspects; the management of pre-analytical errors from the perspective of patient safety, and the improvement and harmonisation of procedures, based on the application of regulations and professional recommendations. Like the rest of the phases, it should include an internal quality assurance program, as well as the participation in external quality assurance programs. The internal quality control should mainly be based on the identification of risks, systematic detection of errors, and establishment of indicators. The selection of indicators prioritising the impact on the patient, the way to detect and record errors in a systematic and easily exploitable manner, and also the variables used in the calculations, are important aspects to measure the effectiveness of improvement actions and to allow comparability between laboratories. In this sense, the external quality assurance programs of the pre-analytical phase based on the comparison of indicators are a useful tool for the design and implementation of a quality assurance program. This document is intended as a support for each laboratory to select, implement, and evaluate its own indicators, according to the individual characteristics of its pre-analytical procedures, but without losing sight of the harmonisation between laboratories
