Total Turnaround Time ofClinical Laboratory – An Assessment tool for Laboratory Performance
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 9
Abstract
Introduction: Diagnostic turn around time is defined as the interval between the time of sample collection and the report dispatched to the patient. Objective of this study was to calculate the turn around time (TAT) for routine investigations done for OPD and IPD patients. We also aimed to find the time required for pre-analytical, analytical and post-analytical phases and their contribution to total TAT in terms of percentage. Methodology: Total of 51,702 samples were analyzed in the Clinical Laboratory, Adarsha Hospital, Udupi. Inpatient specimens accounted for 66% (34,165) and outpatient specimens accounted for 34% (17,537) of the total specimens. Time was noted at the time of phlebotomy, identification, transportation, separation, analysis, reporting and interpretation of the report. The whole process is divided in to pre-analytical, analytical and postanalytical phases. A log book was maintained for this purpose from which total TAT as well as percentage contribution of each phase to total TAT was calculated. Results: The average TAT for the OPD and IPD routine parameters is 65 min& 85 min respectively. Major contribution to TAT is from pre-analytical phase ,around 62% , analytical 25-30% and by post-analytical phase by 7-12%. Conclusion: TAT is an important parameter for the laboratory as well as for the hospital in assessing the laboratory services. It is an important quality indicator as well.TAT for both OPD and IP samples were excellent in our laboratory.
