Pre-Analytical Errors Through Effective Collaboration Between Nurses and Laboratory Professionals

Abstract

The pre-analytical phase of the total testing process is the most vulnerable to errors, accounting for over 60% of all laboratory mistakes. These errors, including misidentification, improper specimen collection, and hemolysis, have significant implications for patient safety, clinical decision-making, and healthcare costs. The execution of this phase predominantly involves nursing staff, while the oversight and consequences fall upon laboratory professionals, creating a critical interface where communication and collaboration failures often occur. This comprehensive review aims to analyze the root causes of pre-analytical errors, with a specific focus on the systemic and communication barriers between nursing and laboratory teams, and to synthesize evidence-based strategies for fostering effective interprofessional collaboration to mitigate these errors. Evidence consistently demonstrates that pre-analytical errors are largely preventable and are best addressed through a collaborative framework. Key findings indicate that strategies such as establishing joint nurse-laboratory quality committees, implementing closed-loop communication technologies, providing continuous interprofessional education, and leveraging data-driven feedback can reduce specimen rejection rates by 30-50% and significantly improve key quality indicators like hemolysis rates. A cultural shift from a siloed, blame-oriented model to a shared, system-based accountability is fundamental to success. Effective, systematic collaboration between nurses and laboratory professionals is the most potent strategy for strengthening the pre-analytical phase. By bridging the interdisciplinary gap through structured communication, shared goals, and ongoing education, healthcare institutions can dramatically enhance the quality of laboratory diagnostics, thereby safeguarding patient safety and optimizing clinical outcomes.
