How Do We Measure Comorbidity?

This chapter reviews methods used to measure comorbidity in the context of cancer; summarising methods, identifying contexts in which they have been used and assessing the validity, reliability and feasibility of each approach. Measures of comorbidity are categorised according to whether they are based on individual conditions or simple counts, on dysfunction/function of organ systems, on condi...

How accurately can we measure the W cross section?

We study the QCD sources of systematic uncertainties in the experimental extraction of the W cross section at hadron colliders. The uncertainties appear in the evaluation of the detector acceptances used to convert the number of observed events into a total production cross section. We consider the effect of NLO corrections, as well as of the inclusion of parton showers, and evaluate the impact...

How accurately do we measure blood glucose levels in intensive care unit (ICU) patients?

Hyperglycaemia is commonly found in critically ill patients as a result of numerous processes such as increased gluconeogenesis and glycogenolysis caused by elevated levels of corresponding hormones and insulin resistance. As the clinical consequence of hyperglycaemia has been shown to increase morbidity and mortality in various clinical settings, many hospitals by now use tight glycaemic contr...

Stroke care: how do we measure quality?

The purpose of this paper is to review the methods used to measure quality of stroke care. Relevant articles were searched for on Medline using the following key words: stroke, quality, outcome of care, process of care, structure of care. Articles that examined how to measure the quality of stroke care and that examined difficulties in the measurement of care outcomes, processes, and structures...
