摘要

NABL (National Accreditation Board for Testing and Calibration Laboratories) accreditation, aligned with ISO 15189 standards, is fundamental for quality assurance in clinical laboratories. Structured training of laboratory technicians during preparation for accreditation is critical for shaping compliance-related attitudes and quality culture. While evidence from private-sector institutions exists, data from tertiary care academic institutions remain limited. A pre–post interventional study was conducted among 30 laboratory technicians at the Department of Laboratory Medicine of a tertiary care academic institution in New Delhi, India. A validated 10-item questionnaire assessing attitudes was administered before and after NABL accreditation training. Responses were scored on a 3-point ordinal scale (1 = best, 3 = worst), and the Stuart–Maxwell test for marginal homogeneity was used to assess changes in attitude distribution for each item. Significant improvements were observed across all 10 questionnaire domains following training. The proportion of participants selecting the most favourable response increased from 20 to 56.7% before training to 83.3–96.7% after training. All changes were statistically significant (Stuart–Maxwell p < 0.01 for all items). The greatest improvements were observed in adherence to protocols (Q5: + 53.3%), training impact on performance (Q6: + 60.0%), and patient safety perception (Q8: + 40.0%). Structured NABL accreditation training was associated with significant improvements in laboratory technicians' attitudes toward quality compliance, protocol adherence, and patient safety. These findings support embedding structured training as an integral component of accreditation preparedness in academic tertiary care laboratories.
