A Cross-Sectional Assessment of Proficiency in Clinical Biochemistry Analytical Techniques among Laboratory Specialists and Technicians in Saudi Arabian Hospitals

Abstract

Clinical biochemistry plays a vital role in the diagnosis, monitoring, and treatment of various diseases. Proficiency in analytical techniques is crucial for accurate and reliable laboratory results. This cross-sectional study aimed to assess the proficiency of laboratory specialists and technicians in clinical biochemistry analytical techniques in Saudi Arabian hospitals. A total of 150 laboratory professionals (75 specialists and 75 technicians) from five major hospitals in Riyadh, Saudi Arabia, participated in the study. Proficiency was evaluated using a validated multiple-choice questionnaire and a practical skills assessment. The mean scores for the questionnaire and practical assessment were compared between specialists and technicians using independent t-tests. Factors associated with proficiency were identified using multiple linear regression analysis. The results showed that laboratory specialists had significantly higher mean scores in both the questionnaire (85.6% vs. 78.2%, p < 0.001) and practical assessment (92.4% vs. 84.5%, p < 0.001) compared to technicians. Years of experience, continuing education, and workplace training were positively associated with proficiency scores. The findings highlight the need for regular proficiency testing, targeted training programs, and continuing education to maintain and enhance the skills of laboratory professionals in clinical biochemistry analytical techniques
