EVALUATION OF THE QUALITY INDICATORS IN HEMATOLOGY LABORATORY – GCRI STUDY

Suchita Patel, Dr. Biren Parikh, Rachna Shah

Abstract


Introduction: Quality indicators in a clinical laboratory are considered as useful tools for continual improvement of the laboratory services.

Aim: The aim of this study was to assess timely performance of the Gujarat Cancer & Research Institute (GCRI) service laboratories in three phases of testing – pre-analytical, analytical and post-analytical, in an effort to improve their performance.

Methodology: The study included an assessment of different quality indicators from central laboratory - Hematology, at GCRI which provide service for the patient care.

Results: Data obtained from a total of 490349 samples collected over a period of three years was used in the study. The overall error rate was found to be 2.72%. The commonly observed indicators were clotted sample (3.62%) followed by low quantity (0.99%) of samples during the pre-analytical phase. In the analytical phase, IQC failure (0.27%) was the most common in the three years study period, TAT outlier was 1.2%, during the post- analytical phase.

Conclusions: Quality indicators are important tools in improving the quality system in a clinical laboratory and patient care.
