[Management of pre-analytical nonconformities]

Area of Science:

• Clinical Laboratory Science
• Quality Management Systems
• Healthcare Operations

Context:

• Pre-examination phase errors significantly impact laboratory test accuracy and patient care.
• Standardized protocols are crucial for managing and reducing laboratory nonconformities.
• Effective quality control in the pre-analytical phase is essential for reliable diagnostic results.

Purpose:

• To enumerate key nonconformities in the pre-examination phase of laboratory testing.
• To define specific actions for addressing identified nonconformities, including sample issues and data corrections.
• To propose a framework for traceability, assessment, and continuous improvement of laboratory quality.

Summary:

• This research details a system for codifying and managing pre-examination nonconformities in clinical laboratories.
• It outlines actions such as sample rejection, information requests, and result cancellations, emphasizing traceability of corrective and preventive measures.
• The study suggests using laboratory information systems and proposes tools for monitoring nonconformity scores and overall quality improvement.

Impact:

• Implementation of this system can lead to reduced diagnostic errors and improved patient safety.
• Standardized management of pre-examination nonconformities enhances laboratory efficiency and reliability.
• The proposed framework supports a culture of continuous quality improvement within laboratory settings.
