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...

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. AIMS: ...

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...

When collecting blood for blood gas analysis, it is important to remove air bubbles from syringes to avoid erroneous results, especially for pO₂, with a number of factors affecting the potential magnitude of the interference to pO₂ by air bubbles.  In this study, we calculate the expected theoretical changes in pO₂...

Arterial blood gases (ABG), a clinical test that involves measurement of the pH of arterial blood and the amount of oxygen and carbon dioxide dissolved in arterial blood, is routinely used in the diagnosis and monitoring of predominantly critically/acutely ill patients being cared for in hospital emergency rooms and...

Differentiating self-limiting from serious lower-respiratory-tract infections (LRTI) based on medical history and physical examination is challenging in primary care. Many family physicians (FPs) empirically prescribe antibiotics to most LRTI patients.  The use of C-reactive protein (CRP) point-of-care testing as an...

In the ED, 25 % of patients with angina pectoris with suspected AMI are wrongly diagnosed (no cardiac involvement). As a result, the patient risks are increased and resources are wasted. We investigated the effect of point-of-care testing (POCT) on ED processes, resource needs, patient risks and overall costs. POCT...

A new parameter called critical reference change value (CrRCV) to be applied for the interpretation of serial measurements of cardiac troponin I (cTnI) is introduced. To illustrate the practical utility of CrRCV a set of clinical examples based on two consecutive cTnI results are presented. Thus three cTnI changes...
