Knowledge of Internal Quality Control for Laboratory Tests among Laboratory Personnel Working in Department of Biochemistry in a Tertiary Care Center: A Descriptive Cross-sectional Study

Le résumé fourni par la source

Introduction: Clinical laboratory holds a central position in patient care, thus, ensuring accurate laboratory test results is a necessity. Internal quality control ensures day-to-day laboratory consistency. However, unless practised, laboratory quality systems cannot be achieved. This depends on the efforts and commitment of laboratory personnel for its implementation. Hence, the aim of this study was to find out the knowledge of internal quality control for laboratory tests among laboratory personnel working in the Department of Biochemistry in a tertiary care centre. Methods: This was a descriptive cross-sectional study conducted from 1 July 2022 to 30 August 2022 after receiving ethical approval from Institutional Review Committee (Reference number: 2341/022). Semi-structured questionnaire was used to assess knowledge on internal quality control. Three non-respondents were excluded. The operational definition of the knowledge domain was set before finalizing the questionnaire. The convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 20 laboratory personnel, 5 (25%) (6.02-43.98, 95% Confidence Interval) had adequate knowledge of internal quality control. The mean knowledge score was 12±2.44. Conclusions: The prevalence of adequate knowledge of internal quality control for laboratory tests among laboratory personnel working in the Department of Biochemistry was similar to the other study done in a similar setting. Keywords: biochemistry; knowledge; laboratory personnel; quality control.
