In Democratic Republic of the Congo (DRC), the laboratory TAT is significantly very long and do not comply with either international standards or the suggestions of customers. However, there is neither a national nor a local strategy to improve the laboratory TAT. The aim of the present study is to develop practical management strategies to shorten clinical laboratory tests’ TAT. This was a qualitative study conducted in Kinshasa. Focus groups and Lean tools were used respectively to generate a wide range of views from a variety of laboratory staff and to eliminate several form of waste in the laboratory flow process. Based on the identified root causes of delay, focus groups participants reported that there is a lot of scope for the improvement of TAT in DRC. Consistent attendance and punctuality are essential. The hospital management should implement the laboratory Information Systems (LIS) and install Middleware. Total laboratory automation, inventory system for all reagents and supplies used in the laboratory, expansion of the sampling area, sufficient number of high-power machine and a clear job description are indispensable. LIS, 3.5 mL BD vacutainer BarricorTM tube and point-of-care testing (POCT) are necessary for workflow improvement. A reduction of 312 minutes was achieved by eliminating or decreasing non-value-added activities. Applying the suggested key strategies, and particularly the new workflow process, is a basis for improving the laboratory tests’ TAT. The algorithm presented can be easily implemented in other laboratories that face this type of problem.

Evaluation of clinical laboratory Tests’ Turnaround Time in a Tertiary Hospital in Democratic Republic of the Congo

引用

Journal of Biosciences and Medicines 2021年第7期9卷 96-111页

The delay in the delivery of laboratory results can be fatal and can even lead to the death of patients. This study was conducted at the clinical laboratory of the University Hospital of Kinshasa (UHK) from October 2020 to April 2021, aimed to evaluate the laboratory tests’ turnaround time (TAT) and to identify reasons for delay. TAT was quantified using a time and motion analysis approach. The evaluation of TAT consisted of comparing the overall intra-lab TAT with the suggested TAT using student t-test at 95% confidence intervals. Brainstorming was the root cause analysis tool used for identifying reasons for delay. In this study, the laboratory tests’ TATs were significantly higher (p laboratory is not meeting the established TAT. Preventive and curative measures must be undertaken to reduce the delay and improve the TAT.

Semen analysis standardization： is there any problem in Polish laboratories？

Asian Journal of Andrology 2013年第5期15卷 616-621页

作者： Renata Walczak-Jedrzejowska Katarzyna Marc hlewsks Elzbieta Oszukowska Eliza Filipiak Leszek Bergier Jolanta Slowikowska-Hilczer Division of Andrology Department of Andrology and Reproductive Endocrinology Medical University of Lodz 91-425 Lodz Poland Division of Reproductive Endocrinology Department of Andrology and Reproductive Endocrinology Medical University of Lodz 91-425 Lodz Poland Diagnostyka Company Ltd Medical Laboratories 31-513 Cracow Poland

The aim of the study was to determine the degree of compliance of Polish laboratories with World Health Organization （WHO） recommendations, with regard to semen analysis methodology. A survey requesting information about methods of semen analysis was distributed to employees of 55 laboratories. Respondents who had participated in external seminological workshops （31%） were termed certified respondents （CR）, the remaining （69%）--non-certified respondents （NCR）. Only one laboratory （6%） in the CR group and none in the NCR were compliant with WHO guidelines for methods and equipment used to evaluate seminal volume, sperm motility, concentration, vitality and morphology. Most problems were of volume measurement （weighing method was reported by 17% of CR and 10% of NCR） and staining method for sperm morphology （Papanicolau or Diff-Quik were found in 33% of CR and 23% of NCR）. A three- or four-point grading of sperm motility was used by the majority of respondents; however, 17% of CR and 37% of NCR did not use a laboratory counter to tally spermatozoa. Although a haemocytometer method was used by 80% of laboratories in each group, the improved Neubauer chamber was used only by 42% of CR and 19% of NCR. In each group, 24% of laboratories did not perform a vitality test. Procedural errors and the interchangeable utilization of two or even three methods to analyse a given parameter was observed in both groups. The results indicate a need for standardisation of the methods and continuous, unified training in semen analysis in Polish laboratories.

Objective:To detect Dientamoeba(D.)fragilis and Enterocytozoon(E.)bieneusi and to assess their genetic characteristics in stool samples submitted for routine examination in a clinical laboratory in Southeastern Brazil.Methods:In this survey,348 stool samples from female and male individuals with age ranging from 0 to≥55 years were analyzed by PCR amplifying and sequencing based on the small subunit ribosomal RNA(SSU r RNA)gene of D.fragilis and the internal transcribed spacer of E.bieneusi.Results:D.fragilis and E.bieneusi isolates were observed in 2.29%(8/348)and 4.59%(16/348)of the samples,respectively.These parasites were detected in stool samples from individuals of both genders,including young children under nine until adults over 55 years old.No statistically significant differences were found.All D.fragilis isolates were classified as genotype 1 and E.bieneusi isolates included genotypes D(n=15)and A(n=1).Conclusions:The findings provide relevant findings on occurrence and genetic diversity of D.fragilis and E.bieneusi,pointing to the need for the diagnosis of these parasites in routine examinations in clinical laboratories.In addition to sensitive diagnostic methods,it is mandatory that these parasites be considered relevant for physicians and laboratory staff.

Background:The quality of laboratory tests has a great impact on diagnosis and patient safety.Various lines of evidence show that pre-analytical errors are the major source of mistakes in the total test process(TTP).The pre-analytical phase is the most vulnerable and complex step that involves many individuals,including clinicians,nurses,workers and laboratory staff,and it is difficult to ensure a sample’s quality in the laboratory.In recent years,many quality indicators have been recommended by the International Federation of clinical Chemistry and laboratory Medicine(IFCC) to improve the quality of the pre-analytical phase.This study aimed to assess the value of the monitoring and analysis of quality indicators(QIs) in the pre-analytical phase Methods:This study was conducted in the diagnostic laboratory of the Second Affiliated Hospital of the Zhejiang University School of Medicine Beginning in January 2013,the laboratory groomed the workflow of samples with improved softwarefor real-time monitoring,analyzed some QIs monthly(i.e,sample loss rate,sample transportation overtime rate and sample unqualified rate),and communicated with relevant individuals or departments in a timely manner.Results:1) In 2013,when the sample workflow was subjected to real-time monitoring and the QIs were assessed monthly,compared with the same time in 2012,the sample loss rate,transportation overtime rate and rejected rate fell from 0.053‰,65.0‰ and 7.83‰ to 0.003‰,15.2‰ and3.84‰,respectively;these differences were statistically significant(Pclinical biochemistry,hematology,hemostasis and immunology analyses during January 2013 and December 2014.Of these samples,7,472(3.85‰)were rejected,and the three main reasons were clotted blood samples(26.57%,1,985/7472),hemolyzed samples(26.35%,1,969/7472) and samples collected with an insufficient volume(26.16%,1,955/7472).Monthly analysis about these QIs can provide some useful information to guarantee sample quality.3) After so
