Practical, transparent prospective risk analysis for the clinical laboratory.

Clinical laboratories rely on robust quality assurance to ensure accurate patient results. Existing methods for identifying risks in laboratory workflows are limited in practical application. Prior research has shown the value of structured risk analysis in other healthcare settings. However, no prior work had resolved how to tailor these methods for laboratory-specific processes. This gap motivated the development of a streamlined approach to prospective risk analysis. The approach needed to be both systematic and adaptable for different laboratory steps. It also required a balance between objectivity and practicality for routine use. The challenge lay in creating a method that could be applied consistently across various laboratory functions. This paper aims to address these limitations through a novel implementation.

This study aimed to develop a practical approach to prospective risk analysis for clinical laboratories. The goal was to create a method that could be applied to key laboratory processes. The method needed to be based on established risk analysis frameworks. It also had to be simple enough for routine use by laboratory staff. The focus was on identifying high-risk process steps and prioritizing corrective actions. The study sought to provide a transparent and repeatable risk assessment method. It aimed to highlight common failure types in laboratory workflows. The ultimate purpose was to improve quality assurance through structured risk identification.

The method was based on the Failure Mode and Effect Analysis framework. It involved breaking down each process into major steps for evaluation. Each step was assessed for failure probability and consequence. A 10-point scale was used to quantify these risk factors. Detection likelihood was also scored for each potential failure. The scores were combined to calculate an overall risk value. Results were organized into matrix tables for easy interpretation. The method was tested on pre-analytical and analytical laboratory processes.

The highest risk scores were observed in stat processing steps. The most frequent failure type was delayed processing or analysis. Inappropriate analysis had the highest average risk score. Identification errors were most often rated as suboptimal. The matrix format allowed for clear visualization of risk levels. The method successfully identified high-risk areas for intervention. It provided a structured way to prioritize risk-reducing measures. The approach proved to be both practical and transparent in its implementation.

The designed PRA method offers a semi-objective way to assess laboratory risks. It enables consistent evaluation of process steps and failure types. The matrix format simplifies the interpretation of risk scores. The method supports practical decision-making for quality improvement. It provides a transparent framework for identifying high-risk areas. The approach is suitable for routine use in clinical laboratories. It can be adapted to different laboratory workflows and processes. The authors suggest it enhances quality assurance through structured risk analysis.
