INTRODUCTION TO COMPASS Fulfilling andmanaging all documentations for point-of-care testing (POCT) competency assessments can be a challenging process in today's laboratory environment. Even with diligent performance of assessment activities for all POCT personnel, it can be difficult to ensure that all pieces of evidence are tracked, stored, and readily available during accreditation inspections. Not surprisingly, one of the most common laboratory inspection citations involves nonconformance with current competency assessment standards. The era of cloud-based laboratory software has allowed for a different approach to aid in competency management while meeting the needs of the modern laboratory and POCT personnel. MediaLab's Compass solution was designed to automate competency processes—providing the ability for point-of-care coordinators to deliver custom competency assessments to employees that perform POCT or provider-performed microscopy (PPM) procedures. The Compass program creates custom competency assessment profiles for each device or test method, which are assigned, completed, and tracked online to present a complete picture of your POCT and PPM competency assessment program.
在当今的实验室环境中,实现和管理护理点测试(POCT)能力评估的所有文件可能是一个具有挑战性的过程。即使所有POCT人员都勤奋地进行评估活动,也很难确保在认证检查期间跟踪、存储和随时可用所有证据。毫不奇怪,最常见的实验室检查引用之一涉及不符合当前的能力评估标准。基于云的实验室软件的时代允许一种不同的方法来帮助能力管理,同时满足现代实验室和POCT人员的需求。MediaLab的Compass解决方案旨在实现能力流程的自动化,为护理点协调员提供定制的能力评估,以执行POCT或供应商执行的显微镜(PPM)程序。Compass程序为每个设备或测试方法创建自定义的能力评估文件,这些文件被分配、完成并在线跟踪,以呈现您的POCT和PPM能力评估程序的完整画面。

Abstract Point of care testing (POCT) international normalized ratio (INR) devices are widely accepted for self-testing and self-management of vitamin K antagonists (VKAs). The aim of this work was to evaluate the performance of a POCT at our thrombosis centre aiming at reducing the time spent by patients for blood sampling and dose adjustment. A total of 101 consecutive oral anticoagulated patients (53 M, 48 F, median age 74 years, 23–89) were enrolled in the study that consisted of 2 different phases. In the first, standard monitoring was carried out for 3 months; during this period, the INR value was also determined by capillary blood sample with the use of a POCT to compare the INR values obtained with the two systems. In the second phase, patients were monitored for 3 months using only the CoaguChek XS Plus. The Bland-Altman test showed a good agreement between INR values obtained with the automated coagulometer and the CoaguChek XS Plus. The Passing and Bablok test showed no significant deviation from linearity. The total median waiting time was 3 hours and 45 minutes (from 0:44 to 6:05) and 1 hour and 16 minutes (P < 0.001) during standard monitoring and the use of the CoaguChek XS Plus, respectively. CoaguChek XS Plus is a suitable POCT for monitoring VKA therapy at a thrombosis centre, thus significantly reducing the time spent by patients for blood sampling and waiting for dosage adjustment.
护理点检测(POCT)国际归一化比率(INR)装置被广泛接受用于维生素K拮抗剂(vka)的自我检测和自我管理。这项工作的目的是评估POCT在我们血栓中心的性能,旨在减少患者用于血液采样和剂量调整的时间。共有101例连续口服抗凝患者(53例M, 48例F,中位年龄74岁,23-89岁)纳入研究,研究分为2个不同的阶段。第一阶段进行3个月的标准监测;在此期间,还通过毛细管血液样本测定INR值,并使用POCT比较两种系统获得的INR值。在第二阶段,仅使用CoaguChek XS Plus对患者进行3个月的监测。Bland-Altman试验表明,自动凝血仪和CoaguChek XS Plus获得的INR值吻合良好。通过和Bablok检验显示线性无显著偏差。在标准监测和使用CoaguChek XS Plus期间,总中位等待时间分别为3小时45分钟(0:44至6:05)和1小时16分钟(P < 0.001)。CoaguChek XS Plus是一种适合在血栓中心监测VKA治疗的POCT,从而大大减少了患者采血和等待剂量调整的时间。

Background and Aims Coagulation abnormalities are relatively common among septic patients. The standard of care for preventing thrombosis in critically ill patients is subcutaneous administration of unfractionated heparin 2 or 3 times a day, which fails in some cases. We studied the influence of continuous intravenous infusion of equivalent doses on coagulation profile using rotational thromboelastometry. Subjects and Methods Patients were randomly allocated to the subcutaneous group (n = 15) or infusion group (n = 15). The subcutaneous group received 5000 units 3 times a day, whereas the infusion group received heparin 500 units/hour intravenously. Results Clotting times were significantly lower in the infusion group compared with the subcutaneous group on days 2 and 7 (P < 0.05). Clot formation times were also significantly lower in the infusion group both on days 2 and 7 (P < 0.05). Conclusions Intravenous infusion of low-dose heparin might provide more efficient thromboprophylaxis in septic patients. This method could be used in those who are at higher risk of thrombosis.
背景与目的凝血功能异常在脓毒症患者中较为常见。预防危重患者血栓形成的标准护理是每天皮下注射2或3次无分离肝素,但在某些情况下无效。我们使用旋转血栓弹性测量法研究了等量连续静脉输注对凝血特性的影响。患者随机分为皮下注射组(n = 15)和输液组(n = 15)。皮下注射组给予肝素5000单位,每日3次,静脉注射组给予肝素500单位/小时。结果输液组第2、7天凝血时间明显低于皮下组(P < 0.05)。输液组在第2天、第7天的凝块形成时间也显著低于对照组(P < 0.05)。结论静脉滴注低剂量肝素可有效预防脓毒症患者血栓形成。这种方法可用于血栓形成风险较高的人群。

Abstract Although many qualitative point-of-care tests are commercially available for detection of pregnancy including urine and serum human chorionic gonadotropin (hCG) tests, these products are often associated with higher risk of false-negative results and are not easy to use. The ADEXUSDx hCG Test uses only 1 drop (35–40 &mgr;L) of whole blood sample for the detection of hCG, making it suitable for capillary blood testing. Comparison with Access Total &bgr;hCG (5th IS) assay using 392 finger stick samples from women of child-bearing age demonstrated an overall agreement of 98.1%. Performance of the ADEXUSDx hCG Test was prospectively evaluated in 40 pregnant and 40 nonpregnant women aged 18 to 44 years. The hCG test generated 100% sensitivity and 100% specificity. Study of additional 318 nonpregnant women in various age groups demonstrated 99.7% specificity. The ADEXUSDx hCG Test is a rapid test (10 minutes) with demonstrated ease of use and clinical performance, making it a useful point-of-care test as well as over-the-counter test.
虽然许多定性的即时检测方法在商业上可用于妊娠检测,包括尿液和血清人绒毛膜促性腺激素(hCG)检测,但这些产品往往与假阴性结果的高风险相关,而且不容易使用。ADEXUSDx hCG检测只需要1滴(35-40 μ L)全血样本检测hCG,适用于毛细管血液检测。与使用来自育龄妇女的392个手指棒样本的Access Total &bgr;hCG (5th IS)检测相比,结果总体一致性为98.1%。对40名18至44岁的孕妇和40名非孕妇进行ADEXUSDx hCG测试。hCG测试产生100%的敏感性和100%的特异性。另外318名不同年龄组的未怀孕妇女的研究显示出99.7%的特异性。ADEXUSDx hCG测试是一种快速测试(10分钟),证明易于使用和临床性能,使其成为一种有用的护理点测试以及非处方测试。

Abstract Diagnosing illicit substance and drug intoxications in prehospital setting may be difficult. Invasive treatment procedures might be avoided with substance specific antidote treatment. An oral fluid (OF) screening device may aid differential diagnostics in the care of a patient suffering from an unknown intoxication or unconsciousness. The aim of this study was to evaluate whether on-site OF screening improves the diagnosis and treatment of emergency medical service (EMS) patients with lowered level of consciousness due to suspected intoxication or an unknown cause. A retrospective analysis was conducted on patients who were treated by a mobile intensive care unit due to a lowered level of consciousness and tested with an OF screening device. Patient characteristics, the cause of EMS activation, and screening test results were recorded from EMS run sheets, hospital medical records, and laboratory data. Prehospital treatment was evaluated in regard to the OF screening result. A total of 57 patients were tested during the study period. Of these, 8 were excluded owing to missing screening results. Of the final 49 patients (35 males, 14 females), 16 patients (33%) tested positive for one or more substances. In 6 (38%) of the 16 patients, treatment was modified based on the screening results, and in 4 of these cases, there was a clinically relevant prehospital response. Oral fluid screening for illicit substances can be a valuable diagnostic tool in addition to the usual diagnostic methods in EMS patients with unconsciousness due to an unknown cause or intoxication.
院前诊断非法物质和药物中毒可能是困难的。针对特定物质的解毒剂治疗可以避免侵入性治疗程序。一种口腔液(OF)筛查装置可以帮助鉴别诊断患有不明中毒或昏迷的病人。本研究的目的是评估现场of筛查是否能改善急诊医疗服务(EMS)患者因疑似中毒或原因不明而意识水平降低的诊断和治疗。回顾性分析了由于意识水平降低而在流动重症监护病房治疗的患者,并使用of筛查装置进行了测试。从EMS运行表、医院医疗记录和实验室数据中记录患者特征、EMS激活原因和筛选测试结果。院前治疗根据OF筛查结果进行评估。在研究期间,共有57名患者接受了测试。其中8例因筛查结果缺失而被排除。在最后的49名患者(35名男性,14名女性)中,16名患者(33%)对一种或多种物质检测呈阳性。16例患者中有6例(38%)根据筛查结果修改了治疗方案,其中4例出现了与临床相关的院前缓解。对于因不明原因或中毒而失去意识的EMS患者,除了常用的诊断方法外,口腔液体筛查非法物质是一种有价值的诊断工具。

Abstract A recent increase in the number of point-of-care (POC) international normalized ratio (INR) measurements greater than 4 and the need for venous confirmatory testing in an academic family medicine clinic has led to the further exploration of the accuracy of POC INRs greater than 4. The primary objective of this quality improvement project was to compare the POC INR measurements with confirmatory venipuncture INR measurements. Seventeen patients representing 41 separate encounters over a 20-month period were retrospectively reviewed. The median POC INR was 4.5 (interquartile range, 4.1 to 5.1) versus a median venous INR of 3.4 (interquartile range, 3 to 3.9) of the 27 patient encounters where a venous INR was available. This difference between POC and venous INR resulted in a change in therapy for over 80% of the patients, which is a higher-than-reported discrepancy between POC INRs and venous INRs in patients with a POC INR greater than 4. Clinicians using the results of these POC devices who are unaware of the potential positive bias in POC INR values compared with venous draw values are at risk for making warfarin dose reductions, which can put their patients at risk for thromboembolic events.
近年来,随着医疗点(POC)国际标准化比值(INR)测量值大于4的数量的增加,以及学术家庭医学诊所对静脉确认试验的需求,导致了POC INR大于4的准确性的进一步探索。该质量改进项目的主要目的是比较POC INR测量值与确认性静脉穿刺INR测量值。在20个月的时间里,我们对17名患者进行了回顾性研究。在27例可获得静脉INR的患者中,POC INR中位数为4.5(四分位数范围4.1至5.1),而静脉INR中位数为3.4(四分位数范围3至3.9)。POC和静脉INR之间的差异导致超过80%的患者改变了治疗方法,这比POC INR大于4的患者的POC INR和静脉INR之间的差异要高。使用这些POC装置结果的临床医生如果没有意识到POC INR值与静脉抽吸值相比存在潜在的正偏倚,则有减少华法林剂量的风险,这可能使患者面临血栓栓塞事件的风险。

Objectives The objectives of this study were to demonstrate the effect of albumin and pH on total and ionized calcium (TCa, iCa) and total and ionized magnesium (TMg, iMg) in a tertiary level hospital. The ionized fraction was tested on 2 different blood gas analyzers (Nova Prime Plus and Siemens RapidPoint 500), whereas iMg was only available on the Prime Plus. Methods The study consisted of 3 parts. Part 1 was to investigate the effects of increasing albumin by using a pooled serum sample and then spiking aliquots with Albumix to provide a wide concentration range. Part 2 investigated the effects of pH in fresh whole blood and pooled serum by spiking the aliquots with sodium hydroxide (NaOH) or hydrochloric acid (HCl) to provide a wide concentration range. The final part was to determine the percentage range of the ionized fractions in normal samples. Results Total calcium and iCa decreased by 0.01 mmol/L per 1 g/L with increasing albumin at a similar rate in response to increasing albumin concentration. Total magnesium and iMg also decreased but to a lesser degree by 0.003 and 0.005 mmol/L, respectively. As the pH increased, iCa decreased by approximately 0.04 mmol/L per 0.1 pH units in both sample types. The iMg decreased at a much smaller magnitude, by 0.002 mmol/L in whole blood and 0.001 mmol/L in serum per 0.1 pH unit. The ionized fraction percentages in the normal samples were as follows: iCa, 51% (44–57), and iMg, 69% (61–77). Conclusions The iCa and iMg should be routinely measured, owing to their clear inverse relationship with albumin and pH. Routine measurement of the ionized fractions would avoid the need for correction factors and would highlight the physiologically active ion concentration for better patient care decisions.
目的探讨白蛋白和pH值对三级医院总钙和电离钙(TCa, iCa)和总镁和电离镁(TMg, iMg)的影响。电离后的部分在两种不同的血气分析仪(Nova Prime Plus和Siemens RapidPoint 500)上进行测试,而iMg仅在Prime Plus上可用。方法本研究分为三个部分。第1部分是研究增加白蛋白的效果,方法是使用混合血清样本,然后用白蛋白混合液进行等分,以提供一个宽的浓度范围。第2部分研究了新鲜全血和混合血清中pH值的影响,方法是用氢氧化钠(NaOH)或盐酸(HCl)在溶液中增加pH值,以提供一个广泛的浓度范围。最后一部分是确定正常样品中电离组分的百分比范围。结果随着白蛋白浓度的增加,总钙和总钙含量每1 g/L随白蛋白浓度的增加而降低0.01 mmol/L。总镁和iMg也分别下降了0.003和0.005 mmol/L,但幅度较小。在两种样品类型中,随着pH值的增加,iCa每0.1 pH单位减少约0.04 mmol/L。iMg下降幅度要小得多,每0.1 pH单位全血下降0.002 mmol/L,血清下降0.001 mmol/L。正常样品的电离分数百分比如下:iCa, 51% (44-57), iMg, 69%(61-77)。结论:由于iCa和iMg与白蛋白和ph呈明显的负相关关系,因此应常规测量。常规测量电离部分可以避免校正因子的需要,并可以突出生理活性离子浓度,从而更好地制定患者护理决策。

H ypoglycemia (blood glucose [BG], <2.6 mmol/L) is common in neonates during the first week of life. Although this may be physiologically normal, hypoglycemia can be pathological leading to neurological impairment. All infants therefore considered at risk for hypoglycemia undergo BG monitoring after birth. However, identifying those actually at risk from lowBG levels due to impaired counter regulation is challenging. Medical interventions need to balance the risks from hypoglycemia with the potential harm from medical interventions and the need to separate mother and baby. Development of point-of-care (POC) technology that measures alternative fuels (ketones and lactate) could provide the means to identify those infants at significant risk, while avoiding unnecessary separation.
低血糖症(血糖[BG], <2.6 mmol/L)在新生儿出生后的第一周很常见。虽然这可能是生理上正常的,但低血糖可能是病理性的,导致神经损伤。因此,所有被认为有低血糖风险的婴儿在出生后都要进行BG监测。然而,识别那些由于反监管受损而导致的低血糖水平的实际风险是具有挑战性的。医疗干预需要平衡低血糖的风险与医疗干预的潜在危害以及母婴分离的需要。检测替代燃料(酮类和乳酸)的即时护理(POC)技术的发展可以提供识别那些有重大风险的婴儿的手段,同时避免不必要的分离。
