INTRODUCTION: The national Laboratory Error Classification System (LECS) was developed to for improve the quality processes of laboratory and patient security by the Turkish Ministry of Health in 2015. In this study, we aimed to evaluate the total laboratory process and quality indicators (QIs) in biochemistry laboratories according to LECS
METHODS: This retrospective study included 4757 samples according to LECS of total 649001 samples between 1 October 2015 and 30 December 2016. The number and type of rejected samples were obtained by the laboratory information system of Balıkesir State Hospital. Laboratory processes were organized according to the LECS. The following were counted on a monthly basis. The data were expressed in percentage.
RESULTS: The rates of pre-, intra-, and post analytical phases were 81.7%, 1.7%, and 16.6%, respectively. The maximum error type was clotted samples (0.28%). The main place of error was emergency service (25.6%). The error time intervals were between 8: 00-12: 00 to 12: 00-16: 00 hours (30%). The major profession group which made errors was the nurse group (64.6%).
DISCUSSION AND CONCLUSION: Different QIs have been used in clinical laboratories in Turkey and in the world in recent years to comply with the requirements of accreditation standards. In the present study, we evaluated QIs according to LECS. These indicators provide a means to compare the performance of individual laboratory with other laboratories. We believe that this results will contribute to the future laboratory total test procedures and to reduce the error rates.
