Over the years, as clinicians have learned how to utilize it, permissive hypercapnia has been finding a place in healthcare. However, it is important to bear in mind that numbers do not tell the entire story. It is imperative to understand the entire clinical picture before you act. For example, an acidic pH of 7.21...

The following is a copy of an article from Evidence-Based Practice, 2007; 10(12):1-2. Venous thromboembolism refers to a spectrum of disease that includes both pulmonary embolus and deep-venous thrombosis (DVT). More than 250,000 people in the United States are diagnosed annually with venous thromboembolic disease;...

PURPOSE – The purpose of this article is to discuss lean as a learning system in a hospital ward. DESIGN/METHODOLOGY/APPROACH – Discusses lean as a learning system in a hospital ward. FINDINGS – The Toyota veterans are fond of saying, lean is about “making people before making parts” or, in the wards’ context,...

BACKGROUND: Besides actual pH, base excess (ctH⁺_B (mmol/L)) is of major importance since it is meant to reflect lactate acidosis due to fetal hypoxia; in vivo BE_B is not independent from pCO₂. Independence is achieved by using the extended extracellular fluid (Ecf) for dilution of hemoglobin (cHb_B), reducing cHb_B to ...

CONTEXT: Sensitive D-dimer assays have been developed to exclude the diagnosis of deep vein thrombosis (DVT) and have exhibited great success when used in conjunction with a diagnostic algorithm, including pretest probability scoring and a compression ultrasound (CUS). Improving specificity of D-dimer assays would...

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...

Tight glycemic control (TGC) in the intensive care unit is essential to comprehensive clinical management.  However, TGC that is too aggressive in the wrong patient populations (particularly non-diabetics) can result in hypoglycemia, which brings with it a set of sequelae that can increase morbidity and mortality....

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 ...

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...

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...
