To measure the accuracy of automated tuberculosis case detection.

The Model for Assistance in the Orientation of a User within Coding Systems (MAOUSSC) project has been designed to provide a representation for medical and surgical procedures that allows several applications to be developed from several viewpoints. It is based on a conceptual model, a controlled set of terms, and Web server development. The design includes the UMLS knowledge sources associated with additional knowledge about medico-surgical procedures. The model was [...]

The authors provide a survey of how images are used in radiation therapy to improve the precision of radiation therapy plans, and delivery of radiation treatment. In contrast to diagnostic radiology, where the focus is on interpretation of the images to decide if disease is present, radiation therapy quantifies the extent of the region to be treated, and relates it to the proposed treatment using a quantitative modeling system called [...]

Objective: To use routine data from a comprehensive electronic medical record system to predict death among patients with reactive airways disease. Design: Retrospective cohort study conducted in an academic primary care internal medicine practice. Subjects were 1,536 adults with reactive airways disease: 542 with asthma and 994 with chronic obstructive pulmonary disease (COPD). Measurements: The dependent variable was death from any cause within 3 years following patients' first primary care [...]

To explore the informatic requirements in the home care of chronically ill patients.

United States health care is engaged in an ambitious project to make its clinical and administrative records "100% electronic." Substantial benefits are expected in both clinical care delivery and medical research (especially for public health surveillance and outcomes/effectiveness studies). Substantial costs also potentially accrue, beyond the large outlays for an expanded computer and telecommunications infrastructure. Privacy and confidentiality are obviously at risk if such systems cannot be made secure. Limited [...]

To compare three potential sources of controlled clinical terminology (READ codes version 3.1, SNOMED International, and Unified Medical Language System (UMLS) version 1.6) relative to attributes of completeness, clinical taxonomy, administrative mapping, term definitions and clarity (duplicate coding rate).

We evaluate the ability of a microcomputer program (Automatch) to link patient records in our hospital's database (N = 253,836) with mortality files from California (N = 1,312,779) and the U.S. Social Security Administration (N = 13,341,581). We linked 96.5% of 3,448 in-hospital deaths, 99.3% for patients with social security numbers. None of 14,073 patients known to be alive (because they were subsequently admitted) was linked with California deaths, and [...]

The Digital Imaging and Communications in Medicine (DICOM) Standard specifies a non-proprietary data interchange protocol, digital image format, and file structure for biomedical images and image-related information. The fundamental concepts of the DICOM message protocol, services, and information objects are reviewed as background for a detailed discussion of the functionality of DICOM; the innovations and limitations of the Standard; and the impact of various DICOM features on information system users [...]
