Patient Safety in Laboratory Medicine

Excerpt

Laboratory medicine in the healthcare system has recently been recognized as a fundamental service in the clinical decision-making process. Therefore, the notion of patient safety in laboratory medicine must be recognized as the assurance that harm to patients will be avoided, safe care outcomes will be enhanced through error prevention, and the total testing process (TTP) will be continuously improved.

Although the goal for patient safety is zero errors, and although laboratory professionals have made numerous efforts to reduce errors in the last few decades, current research into laboratory-related diagnostic errors highlights that: (a) errors occur at every step of the TTP, mainly affecting phases at clinical interfaces; (b) despite the improvement strategies adopted, analytical quality remains a challenge; (c) errors are linked not only to clinical chemistry tests, but also to new, increasingly complex diagnostic testing.

Medical laboratories must therefore implement effective quality assurance tools to identify and prevent errors in order to guarantee the reliability of laboratory information. Accreditation in compliance with the International Standard ISO 15189 represents the first step, establishing processes with excellence requirements and greater expectations of staff competency. Another important step in preventing errors and ensuring patient safety is the development of specific educational and training programs addressed to all professionals involved in the process, in which both technical and administrative skills are integrated. A wide variety of information is provided by a robust quality management system and consensus-approved Quality Indicators (QI) that identify undesirable events, evaluate the risk to the patient, and call for corrective and preventive actions. However, the effectiveness of the system depends on the careful analysis of data collected and on staff awareness of the importance of laboratory medicine to the healthcare process. The main task of the new generation of laboratory professionals should be to gain experience in “clinical laboratory stewardship.” In order to safeguard patients, laboratory professionals must assist clinicians in selecting the right test for the right patient at the right time and facilitate the interpretation of laboratory information.
