Abstract
Sigma metrics is calculated in our lab and evaluated from December 2013 to November 2014. It is observed that Triglycerides,Lactate,Uric acid,AST, Urea,Creatine kinase(CK), Phosphate, Total Bilirubin are the best performers and the sigma value is more than 6.0 in both in normal and abnormal levels.Iron and Creatinine are best performers in normal level and Prolactin and Vitamin B12 are best performers in abnormal level. Amylase and LDH are the poor performers at level 1 ( normal), though they show sigma between 3 to 6 at level 2 which is clinically acceptable.
Highlights
It is the time to improve the quality accompanied by reduction of cost in healthcare system of both public and private sectors
Among the 23 analytes observed in Level 1 Triglycerides, Lactate, Uricacid, Iron, AST, Urea, Creatine kinase, Phosphorus, Prolactin, Total Bilirubin, Creatinine showed the performance of more than 6 sigma
Rule 10 x indicates ten consecutive control observations falling one side of the mean is a rejection rule that is sensitive to systematic error.[2]
Summary
It is the time to improve the quality accompanied by reduction of cost in healthcare system of both public and private sectors. This pressurises to implement Total Quality Management which includes Quality planning, Quality Laboratory Process, Quality Control, Quality assessment, Quality Improvement. Fundamental requirements for all objective quality control systems are clearly defined quality goals. Laboratories must define their service goals and establish clinical analytical requirements for testing processes. Without such quality goals, there is no objective way to determine whether acceptable quality is being achieved
