Because measurements of GFR are tedious, estimated GFRs based on creatinine or cystatin C are widely used for assessing kidney function. Both measured GFRs and the Staging System for CKD based on GFR have analytical and clinical shortcomings. The advantages of serum creatinine and cystatin C, and eGFR will be...

This article explores the potential benefits of point-of-care testing in the ED. Price and St. John provide a detailed description on how to approach four common aspects of point-of-care testing (POCT) in the ED, specifically, the challenges of adopting POCT, the impact of POCT on clinical decisions, the impact of...

This article discusses the use of a D-dimer assay in excluding venous thromboembolism (VTE) in outpatients. Together with a low pretest probability of VTE, a negative D-dimer test can rule out VTE in 30-50 % of suspected patient cases. The article highlights the importance of using a D-dimer assay with particular...

Procalcitonin (PCT) is a biomarker which is elevated in bacterial infection. Usefulness of PCT measurements in community-acquired pneumonia (CAP) has to be proven by many studies. A single measurement of PCT on admission or outpatient visits is useful to diagnose CAP, estimate causative pathogens pattern, and for...

Bacterial infections are one of the major reasons for patients presenting to the ED - and the main cause of death in elderly patients. It is important to identify elderly patients with bacterial infections early and initiate treatment in the ED for a better outcome. However, an infection in an elderly patient can be...

This short review aims to put the diagnostic options provided by state-of-the-art POCT  technology into perspective with the clinical challenges faced by physicians treating patients presenting with acute dyspnea.  Natriuretic peptides, hemoglobin, D-dimers and venous blood gases play a key role in the early...

Barnsley Emergency Department (ED), which recruited patients into the RATPAC trial, initiated a point-of-care (POC) pathway for low-risk chest pain patients from December 2011. All patients who underwent POC testing for chest pain between December 2011 and July 2012 were identified. Patient notes were then examined...

In the past years, emergency rooms (ER) all over Germany, especially those of maximum-care hospitals, have been faced with an increasing number of patients. This is caused by a variety of factors, including demographic changes, inflexible ambulant services and an overreaching demand for healthcare services. ER...
