Making better decisions: construction of clinical scoring systems by the Spiegelhalter-Knill-Jones approach.
A study was carried out assessing the practical use of a simple system of scoring information which can help in making a diagnosis or establishing a prognosis in an individual patient. The system was introduced in 1984 for use in gastroenterology, but it can be employed in a wide range of medical and surgical settings. This series was concerned with predicting postoperative respiratory complica...
متن کاملClinical Scoring Systems in Thrombosis and Hemostasis.
Welcome to this special theme issue of Seminars in Thrombosis &Hemostasis on “clinical scoring systems in thrombosis and hemostasis.” Clinical scoring systems (CSSs) are known by many other names including clinical prediction rules, clinical decision rules, probability assessments, prediction models, and risk scores.1 Nomatter which term is used, CSSs are tools that quantify the individual cont...
متن کاملClinical review: Scoring systems in the critically ill
General illness severity scores are widely used in the ICU to predict outcome, characterize disease severity and degree of organ dysfunction, and assess resource use. In this article we review the most commonly used scoring systems in each of these three groups. We examine the history of the development of the initial major systems in each group, discuss the construction of subsequent versions,...
متن کاملclinical scoring systems in predicting the outcome of acute upper gastrointestinal bleeding; a narrative review
prediction of the outcome and severity of acute upper gastrointestinal bleeding (ugib) has significant importance in patient care, disposition, and determining the need for emergent endoscopy. recent international recommendations endorse using scoring systems for management of non-variceal ugib patients. to date, different scoring systems have been developed for predicting the risk of 30-day mo...
متن کاملConstruction of strict Lyapunov function for nonlinear parameterised perturbed systems
In this paper, global uniform exponential stability of perturbed dynamical systems is studied by using Lyapunov techniques. The system presents a perturbation term which is bounded by an integrable function with the assumption that the nominal system is globally uniformly exponentially stable. Some examples in dimensional two are given to illustrate the applicability of the main results.
