Emergency Department (ED) overcrowding is becoming an increasingly international issue.  Although the problem is not only resolved by ED change management (but rather requires a system-wide solution recognizing the complex interdependencies of consumer expectations, human resources, information systems immaturity and...

Point of care (POC) testing has become an important part of nephrological care. In cases of acute renal failure, POC is indispensible in deciding the need for dialysis, but is also essential in the management of patients on regular dialysis. For example, hyperhydration, cardiovascular adverse events and inflammation...

Few studies have addressed the predictive value of C-reactive protein at different cutoff values in appendicitis. We have determined the cutoff values for C-reactive protein levels at different periods during clinical evolution of appendicitis and established their use to support the diagnosis of appendicitis. The...

Diagnosing heart failure (HF) in patients presenting in primary care is difficult. Clinical assessment of symptoms and signs has limited sensitivity and specificity. NT-proBNP determination has been proven to be useful and accurate for ruling out the diagnosis of systolic HF, and some have even proposed different...

Many authors contend that drawing of umbilical ABGs is a simple method to evaluate the condition of the neonate and ideally would be routinely done for all newborns [13]. Other authors disagree. Appropriate general principles guide clinicians when drawing and interpreting ABGs for all patients. The special needs of...

Calcium is an essential mineral required for numerous biological functions. In circulation, calcium is found in three different fractions, anion-bound, protein-bound and free or ”ionized”. The amount of calcium in each of these fractions is dependent on the concentration of hydrogen ions, anions and plasma proteins....

BACKGROUND: Hospitals in countries with public health systems have recently adopted organizational changes to improve efficiency and resource allocation, and reducing inappropriate hospitalizations has been established as an important goal, as well as avoiding or buffering overcrowding in Emergency Departments.

Chris Price and Andrew St John have followed their book Point-of-Care Testing for Managers and Policymakers with another look at the subject from strategic vision to change management and implementation in Point-of-Care Testing: Making Innovation Work for Patient-Centered Care. In their latest book the authors give...

Clinical biomarker studies seldom follow recommendations for the evaluation of new biomarkers. Therefore it is important to assess any published clinical value of a biomarker or comparison of two or more biomarkers and see whether or not the published study applies to your situation. If the published study does not...

Test results, essential for quality healthcare, constitute more than 70% of patients’ health records. Because quality results are so important, governments around the world mandate a series of laboratory practices to ensure quality.  All laboratories in the United States follow the Clinical Laboratory Improvement...
