The difference between age and average working year of participants according to the graduate degrees (vocational school of health diplomaed, associate degree, bachelors degree) were determined by using one-way ANOVA. For example, the plan-do-check-act cycle (PDCA) (Deming cycle, Shewhart cycle) should be implemented immediately to ensure continuous quality improvement. Atay et al. and Correct reporting answer: the results, What percentage of incorrect results are due to the preanalytical process? Preanalytic error tracking in a laboratory medicine department: Results of a 1-year experience. Because of no standardization in their graduation degrees and not going through the same training process throughout their education, the knowledge about the preanalytical processes differed from each other. 6. Errors Committed After Collection Clotted samples and platelet clumps were seen in 1% of EDTA tubes. The tube storage conditions, identification of the patient, labeling, disinfection procedures, venipuncture procedures, and safety rules with selected items were checked according to the EFLM WG-PRE Phlebotomy Collection Checklist recommendations for blood collection [11]. All these steps were observed during the blood sample collection by the nurses. Yenisehir, Konak, Izmir, Turkey. For the calculation of the error rates in the one-week observation period, the following cut-offs were used: for fill volume, <90%; for hemolysis, (+) in the visual hemolysis chart. 9. FOIA The fill volume, hemolysis, and clot were evaluated in the one-week observation period.The fill volume error was seen in 40% of gel tubes (n= 387); in 242 of the gel tubes the fill volume was <75%, and in 145 of the gel tubes the fill volume was <50%. by taking advantage of international phlebotomy guidelines (4). In general, most of these individuals basic education is 45 years of high school, followed by 25 years of colleague or university, and there is no standardization in their training. Appropriate tourniquet time and release were not applied in 84% of the procedures. Clinical Chemistry, University of Health Sciences, Dr. Abdurrahman Yurtarslan Oncology Training and Research Hospital, Ankara, TUR, 2 2023 Feb 6;13(4):591. doi: 10.3390/diagnostics13040591. showed that educational programs for nursing personnel dramatically decreased the preanalytical sample errors [18]. It was observed that the identification of the patient which seemed to be erroneous in the present study, was performed by the secretaries rather than nurses before blood drawing. long Correct the tourniquet answer: 1 minute should be, Which of the following is not a preanalytical error? Ottomano C. Pre-analytical workstations: a tool for reducing laboratory errors. A winged collection set and syringe with a 23-gauge needle Do not disregard or avoid professional medical advice due to content published within Cureus. Single-use of the holder and the tourniquet were seen only in 3% and 8% of the blood drawing procedures, respectively. Also for the comparison of one-week LIS data, the data for a one-year period were also collected from LIS. (17) and Plebani et al. The vocational school of health graduates were the youngest group in terms of age and their professional experience was lower than the associate degree and bachelors degree. Blood samples are drawn with the guide of LIS in order to use the appropriate tube types and numbers. To maintain analyte value/ stop breakdown Examples of diurnal variation posture, activity, eating, daylight/ darkness, awake/ asleep Before Salkta kalite standartlar Versiyon 5. This study emphasizes the importance of the nurse and laboratory staff training during the preanalytical phase and showed that periodic auditing is essential for implementing the existing procedures. doi: 10.7759/cureus.34444. 8600 Rockville Pike Another similarity with the study of Sumindic et al. Is Correct it possible answer: to palpate No after disinfection? Therefore, it is recommended to establish national guidelines to adapt to local cultural and institutional orientation (considering the language, legislation, moral values, the curriculum and the duration of the training of the operators, their basic education, etc.) Consent was obtained by all participants in this study. The .gov means its official. Did the collector select a suitable venipuncture site according to standard. However, since IQs do not automatically result in quality improvement, we need to reach a consensus on preparation, adoption, and monitoring of standard procedures in the preanalytical phase (19). Quality indicators and specifications for the extra-analytical phases in clinical laboratory management. Bethesda, MD 20894, Web Policies Received 2020 Mar 5; Accepted 2020 Mar 13. Study with Quizlet and memorize flashcards containing terms like What special preparation should be made when drawing blood from a patient whose behavior may be unpredictable or combative?, A phlebotomy technician can cause preanalytical errors by, What equipment would be best to use when performing venipunture on an elderly patient currently un. In contrast, the hemolysis rate in the one-year LIS period was lower than the one-week observation period. official website and that any information you provide is encrypted The https:// ensures that you are connecting to the 8600 Rockville Pike However, while the pre-analytical phase is known to be error-prone, only recently have data been collected to demonstrate that the errors occurring are mainly related to procedures performed outside the laboratory walls, by healthcare personnel not under the direct control of the clinical laboratory. Preanalytical Errors in a Hematology Laboratory: An Experience from a Tertiary Care Center. One-week observation period data and one-year test number data were obtained from the LIS system. Simundic et al. Quality indicators and specifications for key processes in clinical laboratories: a preliminary experience. The number of observations according to the departments is shown in Table Table11. Clinical Chemistry, Manisa Celal Bayar University, Manisa, TUR.

The most common preanalytical error observed was inadequate samples followed by clotted samples. The data for these calculations were obtained from the local Hospital Information System (HIS). Lippi G, Chiozza L, Mattiuzzi C, Plebani M. Patient, Sample Identification. Knowledge about appropriate sampling and preanalytical process can updated by providing training to the beginners before starting to practice and regularly repeating trainings for the senior staff who continue to practice. Did the collector place a clean gauze or cotton ball over the venipuncture site? While the correct answer rates (55.5%) for the question related with turning upside-down of tubes were similar to the rates of the study (44.1%) performed by Yksel et al. Sources of preanalytical errors and the role of training in error prevention. Which Correct test answer: is not Glucose affected by hemolysis? -, Narayanan S.

The observation findings revealed the inadequate education and training procedure of the nurses in the study group and showed that regular education programs must be implemented to them. Which of the following is not a preanalytical error? What are the most common error sources that you were informed? The entry of a test request is performed by clinicians in the laboratory information system (LIS). Level of confidence in venepuncture and knowledge in determining causes of blood sample haemolysis among clinical staff and phlebotomists. Pre analytical errors. Ideal Correct answer: 70%, Which disinfectant should be used before ethanol collecting analysis)? Besides, researches conducted on the clinic staff indicate that training was not associated with venous blood collection practice (10, 11, 12). In the reception unit, the staff receives or rejects samples by checking the identification, container appropriateness and, filling. Did the collector clean the venipuncture site? Serdar MA, Kenar L, Haimi A, Kou L, Trkmen YH, Kurt I. Tourniquet application time during phlebotomy and the influence on clinical chemistry testing; Is it negligible? ), inadequate or excess sampling, sample with clot, hemolyzed sample, sampling to the incorrect tube, sample identification error, patient identification error, and sample transfer errors (late transferring to laboratory or non-arrival). In clinical laboratories, the laboratory staff, especially in the sample reception unit, have to be careful about the written policies for the sample reception and rejection criteria. Aykal G, Keapli M, Aydin , Esen H, Yein A, Gngr F, Yilmaz N. Pre-test and post-test applications to shape the education of phlebotomists in a quality management program: an experience in a training hospital. How Correct long answer: the tourniquet 1 minute should be kept? The present study shows the lack of comparability of the observation period and LIS data. Before Before and after training, questionnaires, consisting of 17 questions which include demographic characteristic and preanalytic phase stages, have been conducted to the relevant personnel (n=324). Especially, the deficient or extensive and mistaken test requests and unsuitable blood sampling errors significantly decreased after training (Table IV). So while true hyperkalemia is a potentially life-threatening clinical condition needing immediate medical intervention, pseudohyperkalemia exhibits no toxic . 1 For the erroneous request, misidentification, improper container or tube, and incorrect fill volume criteria, rejection rates were calculated with the total number of the tubes that were accepted. There are more "P-errors" than "A-errors", therefore, many laboratories believe they should put a higher priority on pre- and post-analytical errors than on analytical errors. The present study was undertaken to find the prevalence and types of preanalytical errors at a tertiary care hospital in South India. Epub 2021 Sep 3. Preanalytical error types especially occur outside the laboratory, and the root cause of the error is human [4,14]. The acceptable filling volume of the citrated tubes was 10% of that marked on the tube. CLSI: Clinical Laboratory Standard Institute. Maximizing the clinical laboratory quality process is gaining increasing importance, and identifying preanalytical errors correctly is becoming critical at each step of this phase. It is also noted that applications such as the use of labeling systems will reduce the preanalytical errors (missing blood sample in particular). WHO Guidelines Approved by the Guidelines Review Committee. Not any significant change rate has been detected only in 9th question related with disinfection during blood sampling at question based analysis. showed that the proportion of identification errors was eight fold higher in the outpatient (collection sites outside the hospital) than in the inpatient samples [17]. The number of the rejected samples registered in the LIS was also determined for the same observation week so the observation period results could be compared with the LIS data. Obuka o preanalitikom procesu obuhvatila je 454 zdrava profesionalca od kojih su veina bile zaposlene sestre. 11. What key roles do Phlebotomist? 2021 Jun 15;31(2):020710. doi: 10.11613/BM.2021.020710. (for EDTA tubes). Accessibility Prothrombin Time (PT) mixing test requested before PT test) could only be monitored from LIS and was seen by 0.11% and 0.01% in one-week and one-year LIS periods. Not any significant difference could have been found between the groups having different academic levels (p=0.111 and p=0.557, respectively) in responses to questionnaire about whether they have pre-information or any pre-training about preanalytical processes. 10 Quality improvement initiatives must . Quality indicators (IQs) defined by Sciacovelli et al. In the study performed by Ozcan et al. HHS Vulnerability Disclosure, Help In fact, Young's Effects of Preanalytical Variables on Clinical Laboratory Tests lists over 50 preventable preanalytical conditions that cause a potassium level to be falsely elevated. Background: zcan O, Greser AS. In literature, there are other studies with low percentage (45.5%) as in our study (13). In the past decades, a 10-fold reduction in the analytical error rate has been achieved thanks to improvements in both reliability and standardization of analytical techniques, reagents, and instrumentation. Requirements typically include a high school diploma or GED, a phlebotomy training program, and potentially some work experience. The percentage of total correct answers in the questionnaire was 59.1% before training and 92.2% after training have showed a statistically significant increase (p<0.001). Clin Chem Lab Med. Then, it was followed up with a Post Hoc test according to variance homogeneity.

Laboratory errors: how to improve pre-and post-analytical phases? International Organization for Standardization (ISO) document 15189:2012 standard is focusing especially on phlebotomy by inclusion the preanalytic processes in to accreditation (8). However, laboratory professionals have recently concentrated more on the preanalytical and postanalytical steps due to the increased frequency of the errors [8]. Sciacovelli L, Plebani M. The IFCC Working Group on laboratory errors and patient safety. be delivered Correct answer: 1 hour. Phlebotomy is an expanding field with excellent career opportunities. In the calculation of the percentage of clotted samples, the following formula was used: number of samples clotted/total number of samples with an anticoagulant checked for clots formula was used.
