Strategies for screening blood for human immunodeficiency virus antibody. Use of a decision support system.

A decision analytic model was used to examine alternative strategies to screen donated blood for human immunodeficiency virus (HIV) using data from the literature and from 1987 blood-screening programs in areas with high and low prevalence of HIV. Sensitivity analyses incorporated uncertainties about HIV infection and test performance. Current screening strategies are estimated to allow 20.

Computers in hospital management and improvements in patients care--new trends in the United States.

This article discusses the current state of informations systems in hospital management. Decision Support Systems (DSS) for the management, administrative and patient care units of the hospital are described. These DSS's include market planning, nurse scheduling and blood screening systems.

Mass screening models for contagious diseases with no latent period.

In this paper, a simplified model describing the stochastic process underlying the etiology of contagious and noncontagious diseases with mass screening is developed. Typical examples might include screening of tuberculosis in urban ghetto areas, venereal diseases in the sexually active, or AIDS in high risk population groups. The model is addressed to diseases which have zero or negligible latent periods.
