Abstract
dc:descriptionMalnutrition is common in surgical patients and may be an important determinant of operative morbidity and mortality. As in all branches of medicine the history is still the more important of diagnosis, so in nutritional assessment the clinical examination is used to identify patients likely to develop nutritionally associated complications (NAC). However to make explicit the implicit information found in clinical history it is necessary the development of the field of applying mathematics to clinical medicine. This thesis, stimulated by the recent advances in probability and decision theory, reintroduces a different form of Bayes's theorem that allows calculation of the patient's probability to develop NACs by adding quantities known as "weights". A weight combines information found in both a symptom's or sign's sensitivity and specificity. Although these statistical calculation cannot replace clinical experience and judgement, calculated probabilities based on weights can provide reasonable estimates and offer valuable lessons in clinical nutritional assessment. This methodology allows to the clinician to involve combinations of clinical symptoms or signs and test results and to choose the optimum course of action for the patient. We conclude that the use of weights and this form of Bayes' theorem should allow clinicians to evaluate clinical nutritional assessment more easily, by quantifying the likelihood of occurrence of a symptom or sign, and use probability theory in their practice. We suggest in the future, both sensitivities and specificities and weights be calculated when new symptoms and tests are evaluated.
