Unlike standard laboratory–based coagulation tests (eg, prothrombin time and activated partial thromboplastin time), it provides a holistic, functional perspective on the entire coagulation process; and point-of-care application provides results more quickly. Across a wide range of clinical settings, thromboelastography can be used to assess the risk of bleeding or thromboembolic events and to guide management of hemostatic equilibrium. Until recently, the principal system for performing thromboelastography was the TEG 5000 analyzer. The TEG 6s system, which consists of the TEG 6s analyzer and disposable cartridges, measures the same properties as the TEG 5000 and was recently developed to increase the ease and precision with which thromboelastography is performed. By measuring the velocity of clot formation, the strength of the clot, contributions of fibrinogen and platelets to clot strength, and the speed/extent of fibrinolysis, a comprehensive insight into the patient's coagulation status is gained. Treatment can then be individualized to ensure effective coagulation management while avoiding exposure to unnecessary treatment. Subsequently, the effect of treatment can be assessed to determine whether further intervention may be required. We review the clinical use of thromboelastography in trauma, cardiovascular surgery, liver transplantation, obstetrics, congenital bleeding disorders, and other settings. Increased uptake of thromboelastography has the potential to improve standards of patient care and to lead to health economic benefits.","PeriodicalId":20262,"journal":{"name":"Point of Care: The Journal of Near-Patient Testing & Technology","volume":"37 6 1","pages":"15–22"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80896047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Spain, there are no data about how these tests are used and where they are performed, and there is no clear vision of what is the role of laboratory regarding these tests. The POCT Committee, in the Spanish Society of Clinical Biochemistry, carried out a survey in order to find out what the situation is with POCT in the country from a laboratory POCT manager's point of view. The survey had 19 questions: 3 for segmentation, 1 for opinion, 13 to obtain specific information about POCT in their hospitals, and 2 about personal information. To enable a response, a survey link was shared in the Spanish Society of Clinical Biochemistry Web page. Responses were obtained via Google Docs Web page, where coworkers were requested to fill in the survey. The survey was answered by 140 laboratories, but only 126 of the responses were considered valid. The survey results generally showed that the situation in Spain is similar to that in other countries as documented by similar national surveys on POCT. The survey also demonstrated room for improvement in POCT practices and a need for governmental regulation to improve POCT processes.","PeriodicalId":20262,"journal":{"name":"Point of Care: The Journal of Near-Patient Testing & Technology","volume":"10 1","pages":"151–160"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80449117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of a potential interaction between antiphospholipid antibodies and the reagent used in the prothrombin time INR assay, there is uncertainty as to the reliability of using POC INR monitors in patients with antiphospholipid syndrome (APLS). The study population consisted of 41 patients on warfarin therapy for either APLS (treatment group) or any other indication (control group). All patients had their INR analyzed by the CoaguChek XS meter and a central laboratory. Overall, the mean INR difference between the CoaguChek XS and laboratory in the APLS patients was 0.6772 (P < 0.0001). In APLS patients, when the laboratory INR was less than 2.0, 2.0 to 3.0, 3.1 to 4.0, or greater than 4.0, the CoaguChek XS differed by averages of 0.0636 (P = 0.4111), 0.6903 (P < 0.0001), 1.1417 (P < 0.0001), and 0.9333 (P = 0.0848), respectively. In the control group the overall mean difference was 0.5456 (P < 0.0001). For laboratory INR values of less than 2.0, 2.0 to 3.0, 3.1 to 4.0, and greater than 4.0, the mean differences from the CoaguChek XS were 0.3000 (P = 0.0003), 0.4444 (P < 0.0001), 1.0444 (P = 0.0002), and 1.3500 (P = 0.0236).

However, POCT is often implemented without supervision by laboratory personnel, which raises concern about the quality of its results. The aim of this study was to determine the quality management practices for POCT in several Nigerian tertiary hospitals. Materials and Method This was a descriptive study of 61 POCT sites at 5 tertiary hospitals across Nigeria. Research laboratories and self-monitoring POCT were excluded. Data were collected using interviewer-administered questionnaires, as well as visual inspection of records and facilities. Results were presented as counts and percentages. Results The predominant POCT was the glucometer (65%). Cost of testing was majorly 0 to 500 naira (<2 US dollars; 78%). Point-of-care testing sites were majorly operated by physicians 40%, and only 26% of the sites had documentation of training on the POCT before use. Method validation was not performed in 81% of the sites. Internal quality control and external quality assessment were performed at 26% and 10% of the sites, respectively. There was no traceability of results on the device to the patients tested at 78% of the sites. Troubleshooting a faulty device was performed by nonlaboratorians at 77% of the sites. Most sites did not involve the laboratory in device procurement (74%), validation (77%), maintenance (78%), troubleshooting (64%), or monitoring the accuracy of the results (74%). None of the hospitals had a POCT committee. Discussion The practice of quality management for POCT in tertiary hospitals was poor because of inadequately trained operators and noninvolvement of the laboratory. Laboratory staff should provide guidance and a framework for POCT implementation to ensure quality results and patient safety.","PeriodicalId":20262,"journal":{"name":"Point of Care: The Journal of Near-Patient Testing & Technology","volume":"28 1","pages":"173–176"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81874057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tight glycemic control protocols are important for preventing ill effects of fluctuating glucose levels. As technology advances, glucometers are getting better in terms of quality of results. The purpose here is to study the quality of glucose meter results in terms of clinical outcomes. The study was conducted in a tertiary care referral hospital. A total of 125 patients were recruited from pediatric wards. Bland-Altman plot, Parke error grid, and surveillance error grid analysis were used for comparing the results of the glucose meters with a standard laboratory method. It was found that there was a significant difference between the results of the 2 methods. Although usually minimal, the glucose meter results deviated from the results of the standard laboratory method. This will affect overall patient care especially in emergency conditions. Sometimes, the risk may be so high that the patient may be mislabeled as hypoglycemic when they actually are hyperglycemic and vice versa. This study is the first of its kind because no similar studies have been reported in the pediatric population. For effective use of glucose meters, the devices should give as accurate results as possible. Results should not only be accurate but also precise, without which critical errors may be possible. We recommend that for any glucose meter there should be regular calibration so that agreement with the reference laboratory method is maintained and effective medical decisions are possible.","PeriodicalId":20262,"journal":{"name":"Point of Care: The Journal of Near-Patient Testing & Technology","volume":"8 1","pages":"164–167"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88271295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
