“…The small percentage of autoverified results for troponin I might explain this. Cheng et al showed very significant decreases in TAT both for the metabolic panel and for troponin I ( 17 ). The median after autoverification was 30.3 and 44.5 minutes respectively, close to ours.…”

BackgroundFor a quicker delivery of laboratory test results to the hospital emergency department (ED), we implemented an autoverification system based on the reference change value (RCV). The aim of this study was to assess how the RCV based autoverification reflected on turnaround time (TAT) and on physician satisfaction.Materials and methodsThe laboratory information system (LIS) was programmed to autoverify the results as long as they were within the range settled by RCV, so that the autoverified results were reported to the physician as soon as the tests were carried out, without any further intervention. We analyzed the same three-month periods’ TAT and verification time (VFT) from the years prior to and following the implementation of RCV autoverification. The change in physicians’ satisfaction levels was assessed using the hospital’s Annual Physician Satisfaction Survey (APSS). Over sixty percent of physicians completed the questionnaire, and the amount of daily ED test requests (nearly three hundred) did not vary throughout the duration of this study.ResultsMann-Whitney U test showed that the VFT was significantly reduced in all the test but troponin I. There were substantial reductions in TAT medians (haemogram, 75%; fibrinogen, 41%; prothrombin time, 40%; sodium, 27%). The percentage of physicians satisfied with the haematological and biochemical tests´ TAT increased from 84% to 93% and from 86% to 91% respectively.ConclusionsOur results reveal that VFT and TAT were severely reduced in most emergency tests, greatly improving physicians’ satisfaction with TAT.

Introduction Turnaround time is one of the most important signs of a laboratory service which many clinicians use to evaluate the quality of the laboratory. Pandemic has enlightened the importance of laboratory medicine in healthcare organizations. Each step in total testing process can be affected by errors essential in laboratory medicine. Our study aims to evaluate the impact of the COVID-19 pandemic on turnaround time. Material and Methods We evaluated turnaround time periods of the routine biochemistry, immunoassay, hematology, hemoglobinopathies, HbA1c and blood-typing. In our study, intra-laboratory turnaround time, which is starting from sample acceptance time to results’ verification time is determined. Defined turnaround time duration for all type of analytes are 1440 min. Time intervals in study as listed; Group 1 (pre-pandemic stage), Group 2 (pandemic stage), and Group 3 (post-pandemic stage). Frequency of samples with a TAT exceeded the laboratory’s cutoff time interval was determined and compared within groups. Results The percentage of exceeded turnaround time of all analytes, except blood typing, hematology and HbA1c in the Group 1 are significantly lower than other groups. With regards to comparing Group 2 and Group 3, percentage of exceeded turnaround times of HbA1c and hematology samples in the Group 3 are found significantly lower than the Group 2 Discussion: Turnaround time can be evaluated as a benchmark of the laboratory performance. Workload of the laboratories should be taken into consideration is specific situations, like pandemic. Giriş Test istem sonuç süresi, laboratuvar kalitesini değerlendirme amaçlı, çoğu klinisyenin kullandığı önemli bir parametredir. Pandemi dönemi, sağlık hizmeti organizasyonlarında laboratuvar tıbbının önemini bir kez daha göstermiştir. Toplam test sürecindeki her bir basamak, laboratuvar tıbbında önemli olan hatalardan etkilenebilmektedir. Çalışmamızın amacı test istem sonuç süresine COVID-19 pandemisinin etkisini göstermektir. Materyal ve Metot Rutin biyokimya, immünassay, hematoloji, hemoglobinopati değerlendirmesi, HbA1c ve kan gruplama parametrelerindeki test istem sonuç süresi değerlendirilmiştir. Çalışmamızda, örneğin kabul zamanı ile sonuçların onaylanma süresi arasındaki fark olarak da bilinen, laboratuvar içi test istem sonuç süresi kullanılmıştır. Laboratuvarımızda belirlenen test istem sonuç süresi, 1440 dk'dır. Çalışma grubundaki zaman aralıkları; Grup 1 (Pandemi öncesi dönem), Grup 2 (Pandemi dönemi) ve Grup 3 (Pandemi sonrası dönem) olarak gruplandırılmıştır. Laboratuvarın belirlediği test istem sonuç süresini aşan örneklerin sıklığı belirlenmiş ve gruplar arası karşılaştırması yapılmıştır. Sonuçlar Grup 1'deki Kan grubu, hematoloji ve HbA1c analizleri dışındaki diğer analizlerdeki test istem sonuç süresini aşan numune sıklıkları, diğer gruplara göre daha düşüktür. Grup 2 ve Grup 3 karşılaştırıldığında, HbA1c ve hematoloji örneklerindeki test istem sonuç süresi aşma sıklığı, Grup 3'de anlamlı düzeyde düşüktür. Tartışma: Test istem sonuç süresi, laboratuvar performansının bir belirteci olarak değerlendirilebilir. Laboratuvarların iş yükü, pandemi gibi spesifik durumlarda göz önünde bulundurulmalıdır.

“…Articles in the literature examining TAT also specify that it is particularly critical for the emergency laboratory because of the importance of time. Cheng et al [14] evaluated the TAT of an emergency department after the installation of a computerized auto verification process and they concluded that statistically significant improvements were recorded for a basic metabolic panel, a comprehensive metabolic panel, and troponin I tests. Goswani et al [15] also investigated the TAT of samples in routine and emergency laboratories for electrolytes prothrombin time testing.…”

Q uality can be defined as the ability of a product or service to satisfy the needs and expectations of the customer [1]. Laboratories have traditionally restricted discussion of quality to technical or analytical quality, focusing on imprecision and inaccuracy [2]. However, timeliness and accuracy are other terms of efficient laboratory management. While they share the concerns of laboratories, clinicians are also interested in the larger quality of service that laboratories offer, including areas such as the cumulative total of test errors, availability, cost, relevance , and timeliness. They need rapid and efficient laboratory service at a low cost [3]. Turnaround time (TAT) can be defined as a marker of timeliness; therefore, it can be used to evaluate the performance of laboratory. According to Lundberg [4], it is necessary to achieve the following steps to perform a laboratory test: ordering, collection, identification, transportation, preparation, analysis, reporting, interpretation, and action. Lundberg also identified the brainto-brain TAT or "total testing cycle" using that 9-step series [5]. Objectives: Accuracy, precision, timeliness, and authenticity are the 4 pillars of efficient laboratory services. Clinical biochemists generally overlook timeliness as an important attribute. However, turnaround time (TAT) is usually regarded by clinicians as the benchmark of laboratory performance. TAT can be classified by tests: priority, population served, etc. The aim of the current study was to both evaluate and compare the TAT of the test panels used in the emergency laboratory of Ankara Numune Training and Research Hospital. Methods: The TAT for tests carried out in the emergency laboratory in 2016 was recorded. The TAT limit for each analyte was determined by the hospital's quality control department. Routine biochemistry, arterial blood gas, troponin, erythrocyte sedimentation rate, complete blood count, beta-human chorionic gonadotropin, coagulation panel, and urinalysis tests were evaluated. Samples were grouped by admission time, day, and staff on duty. Samples that exceeded the TAT limit were determined and compared in terms of sample receipt time, day, and staffing. Statistical analysis was performed using SPSS for Windows, Version 15.0 (SPSS Inc., Chicago, IL, USA). P<0.05 was considered statistically significant. Results: A total of 286,577 samples were analyzed in 2016 in this laboratory. The TAT of 30,129 samples exceeded the established time limit. The mean TAT of the staff who worked a day shift on weekdays was significantly higher than that of other shifts, with the exception of arterial blood gas (ABG) testing (p=0.000 for all panels). The mean TAT of the staff who worked a night shift on weekdays and weekends was statistically different, excluding coagulation (p=0.08) and ABG (p=0.09) tests. Conclusion: It is strongly recommended that all of the staff who work in the laboratory be sufficiently informed and educated about TAT. Additionally, evaluation of TAT should be taken into consideration ...
