C-reactive protein point-of-care testing for respiratory-tract infections in primary care
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...

POCT in the ED - relevant clinical and economical advantages
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...

POC testing in the emergency department: Strategies to improve clinical and operational outcomes
Emergency departments (ED) are challenged by increasing patient visits, overcrowding and prolonged length of stay (LOS). The cause of these problems is multifactorial.
Delays in the laboratory are often perceived as contributing to delays in care and increased LOS. Implementation of selected point-of-care tests in...

D-dimer: Past, present, and future
The following is a copy of an article from Nursing 2007, Fall 2007 Volume 37 Number 8 - Supplement: ED Insider, Pages 14 - 16
The D-dimer level is a measure of clot formation and lysis that results from the degradation of cross-linked fibrin. Widely used as an indicator for the presence of disseminated intravascular ...

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...

D-dimer as a rule-out test for deep venous thrombosis: Gold standards and bias in negative predictive value
Recent studies of D-dimer as a “rule-out” test for deep venous thrombosis (DVT) frequently have used duplex ultrasound rather than venography as the gold standard.
Because duplex ultrasound has limited ability to image the calf veins, there is potential for ultrasound studies to classify patients with calf DVT as...

Troponin Testing and the Tyranny of Distance
Chest pain is a frequent cause of hospitalization and comprises a significant proportion of the acute medical workload in the western world. This issue is compounded for those living in regional or remote communities due to limited access to pathology services and tertiary-referral institutions.
Evidence suggests...

How to Avoid Preanalytical Testing Errors: A Virtual Roundtable Discussion
It is estimated that a majority of all laboratory medicine errors are errors that occur during the preanalytical phase of the laboratory testing cycle. Such errors have a significant impact on patient safety, staff workload, and hospital costs.
Correctly identifying patients and avoiding specimen-labeling errors are...

Patient safety 2007
In 2005, acutecaretesting.org interviewed Dr Michael Astion, an active spokesperson for patient safety and reduction of lab errors, on the main issues surrounding the topic. Since then, a lot has changed… or has it? In a follow-up interview with Astion, acutecaretesting.org gauges the status of patient safety year...
