Experience of the external quality assessment scheme (EQAS) in haematology at C.U. Shah Medical College, Surendranagar.
Keywords:
External quality assessment scheme, quality control, quality assurance, Haematology.
Abstract
Background: The attainment of quality services in a laboratory requires a comprehensive quality assurance program which includes both internal and external quality control material. External quality assessment scheme programs are accepted around the world as an invaluable tool by laboratories to assess the performance of their testing systems. Results are objectively compared to other laboratories, using the same methodologies for every parameter.Aims: The goal of this study was to review EQAS result from time to time in an effort to improve the performance of the laboratory.Methods: Observational study done at C.U. Shah medical college and hospital, Surendranagar from January 2007 to August 2014. In the current study, our EQAS test results have been evaluated for the past 7 years and 8 months from 2007 to 2014.One EDTA whole blood sample for blood cell counts and 2 slides for peripheral smear examination and reticulocyte count are received quarterly in a year from AIIMS. The test results of all Indices of blood samples and peripheral smears for cell morphology and reticulocyte count were analyzed and documented.Results: Satisfactory results were obtained in all the cycles except thrice. Discrepancy was observed in RBC, MCH and platelet counts. Root cause analysis was performed and necessary action was taken.Conclusion: This participation in EQAS over the last 7 years and 8 months has helped us significantly to improve our laboratory services in terms of performance evaluation, Patient care and overall quality of laboratory practices.References
