Laboratory analytical turnaround time is a reliable indicator of laboratory effectiveness. Our study aimed to evaluate laboratory analytical turnaround time in our laboratory and appraise the contribution of the different phases of analysis towards the same. The turn around time (TAT) for all the samples (both routine and emergency) for the outpatient and hospitalized patients were evaluated for one year. TAT was calculated from sample reception to report dispatch. The average TAT for the clinical biochemistry samples was 5.5 h for routine inpatient samples while the TAT for the outpatient samples was 24 h. The turnaround time for stat samples was 1 h. Pre- and Post-analytical phases were found to contribute approximately 75% to the total TAT. The TAT demonstrates the need for improvement in the pre- and post-analytical periods. We need to tread the middle path to perform optimally according to clinician expectations.

Physician Goals and Monitoring of Turn Around Time in Clinical BiochemistryLaboratories are focusing on accuracy of test results, patients and clinicians however are interested in rapid, reliable and efficient service from them. Turnaround time (TAT), is one of the most noticeable signs of laboratory service and is often used as a key performance indicator of laboratory performance. The present study was conducted on 200 samples taken from patients in OPD and Indoor departments, simultaneously over a period of time in the clinical biochemistry laboratory of GMC Jammu, but excluding the results of investigations like hormone assays, tumour markers, etc. The time expended in various phases was retrieved from the recorded data at suitable stations and then statistically analysed. Average TAT in OPD and IPD was found to be 172.5±34.3 and 153.8±41.7 minutes respectively. Pre and post-analytical phases were contributing at the rate of 52.6% to 58.4% of the total time laps or turn around time. Time lapsed during analytical phase could be reduced by using fully automated machines with higher throughput, adoption of efficient quality control procedures, etc, but the manual dispatch of the reports could be replaced by Information Technology based e-prints and messages to reduce the time lapse and correct delivery. The biggest impediment for prompt TAT seemed to be the lack of automated facilities for sample transport. With the changing times, this could be immediately looked upon for an effective systemization and modern practises in the profession.
Turnaround time (TAT) is commonly defined as the time from when a test is ordered until the result is reported which includes the preanalytical, analytical and post-analytical time. Turnaround time (TAT) has been considered as cornerstone for measuring laboratory performance. However there has been lack of consensus among the clinicians and laboratory personnel on interpreting the term “TAT”. A faster TAT has always been solicited in spite of inconclusive data on turnaround time and clinical outcome. Increased attention to patient’s needs is demonstrated by efforts to improve the quality of the entire service provided, e. g reduction of laboratory turnaround time (TAT). The availability of the results from a laboratory in defined time increases the patient’s satisfaction and also proves the clinician’s efficiency. A total of 300 samples were taken for analysis of TAT, out of which 150 were from outdoor patients and 150 from indoor patients. The contribution of the analytical time to...

Monitoring and root cause analysis of clinical biochemistry turn around time at an academic hospital2014 •
Quality can be defined as the ability of a product or service to satisfy the needs and expectations of the customer. Laboratories are more focusing on technical and analytical quality for reliability and accuracy of test results. Patients and clinicians however are interested in rapid, reliable and efficient service from laboratory. Turn around time (TAT), the timeliness with which laboratory personnel deliver test results, is one of the most noticeable signs of laboratory service and is often used as a key performance indicator of laboratory performance. This study is aims to provide clue for laboratory TAT monitoring and root cause analysis. In a 2 year period a total of 75,499 specimens of outdoor patient department were monitor, of this a total of 4,142 specimens exceeded TAT. With consistent efforts to monitor, root cause analysis and corrective measures, we are able to decreased the specimens exceeding TAT from 7-8 to 3.7 %. Though it is difficult task to monitor TAT with the ...
Timeliness is an important quality attribute for any laboratory. Timeliness which is commonly expressed as the turnaround time (TAT) is often used as the benchmark for laboratory performance. Our study evaluated the total TAT, the intralab TAT and contribution of the preanalytical, analytical and post analytical phase to the total TAT. The turn around time (TAT) for routine and emergency for both the outpatients and inpatients were evaluated for one year. The total TAT was calculated from sample reception till the dispatch. The TAT for the routine biochemistry samples for inpatients was an average of 5 h whereas the TAT for the outpatient samples was 24 h. The turnaround time for emergency samples was 1 h. The contribution of the pre and post-analytical phases were 80% in OPD and 62.5% in Ward (IPD) to the total TAT whereas for emergency samples the pre and post analytical phases contribute to 55% & 50% of total TAT for routine parameters and electrolytes respectively. The analysis of TAT demonstrates the need for improvement and improvisation in the pre-analytical and post-analytical phase in order to reduce the total TAT.
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 post-analytical 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.

Turnaround time for common clinical chemistry examinations and root cause analysis for its delayObjectives: Measurement of turnaround time for common clinical chemistry examinations and performing root cause analysis for causes for inadequate turnaround time for examinations. Materials and Methods: The Turnaround Times (TAT) of common biochemistry tests ordered by physicians for OPD, IPD and ICU patients were evaluated. Various time periods were recorded, calculated and evaluated. Root cause analysis for delay in TAT was performed by Ishikawa fishbone method. Results and Conclusions: The study shows that average TAT for OPD patients was 22-23 hours, for indoor patient was 6-7 hours and for ICU patient was 7-8 hours. There was major contribution of report transport system in the total TAT, while actual analytical TAT contributed very small to over all TAT. The study shows that, lack of efficient sample and report transport, lack of man power and lack of electronic transport of report is root cause of delay in TAT.
