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...

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.

Over the years, as clinicians have learned how to utilize it, permissive hypercapnia has been finding a place in healthcare. However, it is important to bear in mind that numbers do not tell the entire story. It is imperative to understand the entire clinical picture before you act. For example, an acidic pH of 7.21...

PURPOSE – The purpose of this article is to discuss lean as a learning system in a hospital ward. DESIGN/METHODOLOGY/APPROACH – Discusses lean as a learning system in a hospital ward. FINDINGS – The Toyota veterans are fond of saying, lean is about “making people before making parts” or, in the wards’ context,...

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...

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...

Tight glycemic control (TGC) in the intensive care unit is essential to comprehensive clinical management.  However, TGC that is too aggressive in the wrong patient populations (particularly non-diabetics) can result in hypoglycemia, which brings with it a set of sequelae that can increase morbidity and mortality....

Analytical methods are often developed at one site and transferred to other sites for routine use. Increasingly, the method development is made by manufacturers of instruments and reagents. Regulatory agencies have ruled that the responsibility for the performance of IVDs in the laboratories mainly should lie with...
