What values are critical?
Chemistry and hematology laboratories long ago developed policies and procedures for so-called " critical values. " These policies ensured timely verbal communications for pre-defined test results understood to reflect life-threatening therapeutically remediable conditions. The critical values concept has penetrated anatomic pathology but only in specific limited settings, usually when an abnor...
متن کاملHow critical are critical care pharmacists?
The beginnings of caring for critically ill patients date back to Florence Nightingale’s work during the Crimean War in 1854, but the subspecialty of critical care medicine is relatively young. The first US multidisciplinary intensive care unit (ICU) was established in 1958, and the American Board of Medical Subspecialties first recognized the subspecialty of critical care medicine in 1986. Cri...
متن کاملHow do surgical pathologists evaluate critical diagnoses (critical values)?
BACKGROUND After introduction of the concept of critical value (CV) in laboratory medicine, some efforts were performed to define possible critical values in surgical pathology. Critical diagnosis (critical value) is a concept recently established in surgical pathology and is a challenging issue among pathologists and clinical specialists. The concept may be the subject of variation according t...
متن کاملA Critical Assessment of Simulated Critical Values
There is a wide variety of statistical problems (e.g., unit root and cointegration tests) where hypothesis testing involves the use of simulated rather than theoretical critical values. We argue that in practice the number of replications used to simulate critical values is often insufficient to provide the degree of precision that is implied. In particular, the number of replications needed is...
متن کاملHomotopy Type and Critical Values
Take M , a finite-dimensional differentiable manifold, and f : M → R a smooth function. Such a function f is called a Morse function if it has no degenerate critical points. Morse theory allows us to connect the topology, in particular the homotopy type, of M with the behavior of f on M . In the following sections, we will state and prove two important theorems in Morse theory. Using these two ...
