On the value of clinical information. Is there a bridge between quantum theory and medical diagnosis?

This paper discusses the problems in assigning a precise value to an item (or group of items) of clinical information. Historical viewpoints are reviewed; the paper illustrates how determinist descriptive thinking has been overtaken by concepts of uncertainty and probability. Four equations are proposed outlining the factors which affect the value of clinical information.

The endoscopic assessment of esophagitis: a progress report on observer agreement.

Background & Aims: The study and management of reflux esophagitis require an endoscopic classification system founded on esophageal lesions that can be reproducibly identified. The aim of this study was to investigate interobserver agreement for the identification of endoscopic lesions typical of reflux esophagitis.

Methods: Paired comparisons of observers' descriptions were obtained.

Assigning value to clinical information--a major limiting factor in the implementation of decision-support systems.

This paper deals with a major difficulty and potential limiting factor in present-day decision support-that of assigning precise value to an item (or group of items) of clinical information. Historical determinist descriptive thinking has been challenged by current concepts of uncertainty and probability, but neither view is adequate. Four equations are proposed outlining factors which affect the value of clinical information, which explain some previously puzzling observations concerning decision support.

An information technology course in the medical curriculum.

This paper concerns the information technology course now running in year 1 of the undergraduate curriculum of the medical school of Leeds University. The background and objectives of the course are described, and the course content is outlined in terms of knowledge and practical skills. By the end of the course, 95% of students could successfully accomplish 95% of the skill tasks taught.
