The Quality Paradox in Medical Laboratories: High Pre-analytical Vigilance Masks Analytical Vulnerabilities in Libya

Abstract

Background: Laboratory reliability is the cornerstone of clinical decision-making and patient safety. This study aimed to evaluate compliance with quality standards among medical laboratory practitioners and analyze the demographic and institutional factors influencing analytical performance. Methods: A cross-sectional analytical design was employed, involving 186 practitioners (N=186). A validated survey instrument assessed compliance across pre-analytical and analytical phases. Advanced statistical tests, including Chi-square (X²) and Spearman’s correlation (r_s), were applied to identify compliance predictors and systemic barriers. Results: The findings revealed a distinct "quality paradox." Practitioners demonstrated high compliance in pre-analytical protocols, with 88.7% for patient identification and 93.5% for sterile tool usage. Conversely, a significant analytical gap emerged, as only 41.9% consistently executed daily Internal Quality Control (IQC). Inferential analysis identified a strong, highly significant positive correlation between educational attainment and protocol adherence (p=0.009). Alarmingly, 61.3% of the cohort lacked formal training in the past year. Excessive workload (43.5%) and resource scarcity were identified as the primary institutional barriers. Conclusion: The study underscores that individual diligence cannot compensate for the lack of automated safeguards and institutionalized training. We advocate for a paradigm shift from manual surveillance to quality automation and the integration of mandatory Continuing Medical Education (CME) into professional licensure. Bridging the analytical gap requires structural reforms to ensure laboratory reliability remains independent of daily operational pressures.
