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...

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.

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...

Pediatric considerations in critical value assignment
Critical values are those associated with imminent danger unless acted upon promptly. Critical value menus often include results that do not fit this definition, leading to highly variable practice in adult and pediatric laboratories.
Existing menus may be subdivided into more uniform tiers of severity: the highly...

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 ...

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...

The utility of natriuretic peptide in the management of patients with acute and chronic heart failure: Insights from randomized controlled trials
Patients with heart failure (HF) experience significant morbidity and mortality and those admitted for acute decompensated HF are at particularly high risk for adverse events.
Hospitalization represents the major component of the high cost associated with the management of patients with HF. Accordingly, early and...

Diagnostic accuracy – Part 1
Basic concepts: sensitivity and specificity, ROC analysis, STARD statement
The discriminative ability of a diagnostic procedure is called diagnostic accuracy, and a number of quantitative measures out of which sensitivity and specificity are mostly used in the biomedical literature can express it.
Each diagnostic-accuracy measure relates to some specific aspects of a diagnostic procedure....

Biomarkers in sepsis: the present and the future
Timely and accurate diagnosis of sepsis is of great importance for the choice of treatment, level of monitoring and prognosis. For this biomarkers could be a significant aid, and thus the search for and application of sepsis biomarkers are of great importance.
Current evidence suggests that C-reactive protein and...

Point-of-care testing, now and in the near future
Introduction of point–of-care testing (POCT) in hospitals requires the use of principles of change management. Manufacturers can support this process.
E-learning programs adapted to the local situation with regular updates, a centralized accreditation and user-registration system and service level agreements are...
