Abdominal aortic aneurysms (AAAs) are currently identified by incidental imaging or ultrasound screening. The potential diagnostic and prognostic value of D-dimer for AAA was assessed in this study. 1260 men from a population-based ultrasound screening study were included, of which 299 had small AAAs monitored by...

Postoperative cardiovascular event including myocardial infarction or heart failure is a major cause of morbidity after non-cardiac surgery. Preoperative evaluation including estimation of the probability of perioperative cardiac event and application of non-invasive testing or beta-blocker has been developed, but...

Point-of-care testing sites continue to increase in number due to the availability of easy-to-use devices that make it possible to provide test results very quickly relative to the central laboratory services. There is, however, mixed review regarding the accuracy and reliability of POCT results for patient care. It...

ROC curves are frequently used to show in a graphical way the connection/trade-off between clinical sensitivity and specificity for every possible cut-off for a test or a combination of tests. In addition the area under the ROC curve gives an idea about the benefit of using the test(s) in question.  ROC curves are...

As healthcare seeks to provide better care with fewer resources, Point-of-Care Testing steps in to move key diagnostic or screening tests to the patient’s bedside. The results can have a significant impact on a patient outcome and operational costs.

The following is a copy of an article from Nursing 2007, Fall 2007 Volume 37 Number 8 - Supplement: ED Insider, Pages 14 - 16 The D-dimer level is a measure of clot formation and lysis that results from the degradation of cross-linked fibrin. Widely used as an indicator for the presence of disseminated intravascular ...

Some of the frequently asked questions are: Should we use BE (base excess) or SID (strong ion difference) as a measure of a metabolic acid-base disturbance?  Is there any difference between BB (buffer base) and SID? Should we use SBE (standard base excess), i.e. BE referring to the expanded extracellular fluid or...

The following is a copy of an article from Evidence-Based Practice, 2007; 10(12):1-2. Venous thromboembolism refers to a spectrum of disease that includes both pulmonary embolus and deep-venous thrombosis (DVT). More than 250,000 people in the United States are diagnosed annually with venous thromboembolic disease;...

PURPOSE – The purpose of this paper is to show how over the last 18 months Bolton Hospitals NHS Trust have been exploring whether or not lean methodologies, often known as the Toyota Production System, can indeed be applied to healthcare. DESIGN/METHODOLOGY/APPROACH – This paper is a viewpoint. FINDINGS – One’s...

When a new D-dimer method is to be implemented either as a substitute for a currently used D-dimer assay or as a supplement, maybe as a point-of-care assay, it is necessary to do a clinical comparison of the "old" assay versus the "new" assay. The major pitfalls in D-dimer comparisons are addressed in this paper.   ...
