Preanalytical variables and its impact on total quality management of clinical biochemistry laboratory- A tertiary referral rural hospital study
Journal Title: International Journal of Clinical Biochemistry and Research - Year 2018, Vol 5, Issue 3
Abstract
Introduction Advances in science and Technology have led to transformation of laboratory diagnostics from manual cumbersome testing methods to fully automated science ensuring accuracy and speed Quality is the core issue for all laboratories and this requires total quality management in the laboratory process in the preanalytical analytical and post analytical phasesObjectives To study and evaluate the types frequency and magnitude of errors in our tertiary health care clinical Biochemistry Laboratory in the preanalytical testing process and its overall impact on Total Quality Management System of our laboratoryMaterials and Methods A prospective observational study samples received for analysis between Jan 2015 to Dec 2015 in the clinical biochemistry section was evaluated for various preanalytical errors We evaluated the frequency and types of preanalytical errors found in our laboratory by monitoring specimes requested for laboratory analyses from both inpatient and outpatient divisions and statistically analyzedResults and Discussion Of the total 138275 analytical requests 6446 466 samples were rejected due to various errors in preanalytical variablesFor the inpatient samples preanalytical error rate was 420 4107 samples the preanalytical variable with highest frequency of occurrence was specimen hemolysis Lipemic sample 100 980 samples For the outpatient sample preanalytical error rate was 575 2339 The variable with highest frequency was requisitions with incomplete patient treating physician information 137 559 Preanalytical errors in laboratories are very common and play a very important role in patient care and treatmentLipemichemolytic samples are known to affect the parameter to be analysed and incomplete patient information leads to error in reporting the patients results which means the post analytical error becomes unavoidable and incomplete treating physician information leads to delayed reporting of critical valuesConclusion Our study observation showed each preanalytical variable to occur at different frequency and plays a very important role in the Total Quality Management system of the diagnostic lab which needs to be addressed on priorityKeywords Preanalytical Analytical Post analytical Total quality management Quality assurance
