Diagnosis of DVT with D-dimer testing and the Wells score
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;...

Benefit of using a D-dimer assay with a high clinical specificity
CONTEXT: Sensitive D-dimer assays have been developed to exclude the diagnosis of deep vein thrombosis (DVT) and have exhibited great success when used in conjunction with a diagnostic algorithm, including pretest probability scoring and a compression ultrasound (CUS).
Improving specificity of D-dimer assays would...

Can lean save lives
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...

Hyperglycemic control in the ICU
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....

Comparing D-dimer assays
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.

Interpretation of laboratory results
Clinical laboratory test results are a very important parameter in diagnosis, monitoring and screening. 70-80 % of decisions in diagnosis are based on laboratory results and more and more laboratory analyses are requested. Thus a lot of data are provided and it is therefore imperative for patient care (and safety)...

Verification of methods and instruments
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...

Diagnostic accuracy – Part 2
Predictive value and likelihood ratio
Sensitivity and specificity define the discriminative power of a diagnostic procedure, whereas predictive values relate to the predictive ability of a test to identify disease or its absence in individuals.
Predictive values are greatly influenced by the prevalence of the disease and should not be generalized beyond ...

D-dimer testing in the treatment and monitoring of septic patients
Sepsis and septic shock lead to local and systemic
activation of different response systems, including coagulation and
fibrinolysis.
Despite numerous attempts the high mortality rate of
these patients has remained stable over the last 20
years.
In this overview the pathophysiological insights and
possible...

Acute care testing at the point-of-care: now and in the future
The field of point-of-care testing (POCT) is entering a period of rapid expansion. This expansion is being driven by new evidence for clinical effectiveness of POCT, and new technologies that allow consolidation of testing onto smaller platforms.
Technological improvements will also lead to increased accuracy for...
