Assessing the impact of community health information networks: a multisite field study of the Wisconsin Health Information Network.

Community health information networks (CHINs) have emerged as a promising new technology to generate cost reductions and support change in the health care industry. The proliferation of CHINs has been thwarted, however, by a conspicuous lack of evidence to support the claims of enhanced efficiency and effectiveness from CHIN participation. A recent study of the Wisconsin Health Information Network, the nation's first fully functioning CHIN, documents the benefits of this emerging technology.

Colorimetric determination of selenium in mineral premixes .

A method is described for determination of sodium selenite or sodium selenate in mineral-based premixes. It is based on the formation of intense-yellow piazselenol by Se(IV) and 3,3'-diaminobenzidine. Mineral premixes typically contain calcium carbonate as a base material and magnesium carbonate, silicon dioxide, and iron(III) oxide as minor components or additives.

Learning disabilities, employment discrimination, and the ADA.

The Americans with Disabilities Act (ADA) of 1990 was intended to prohibit discrimination against individuals with disabilities. Although the scope of this legislation is broad, there are aspects of Title I and Title II of the ADA that may be of particular interest to persons with learning disabilities who are preparing for employment. This article discusses those aspects and presents case studies to demonstrate how the ADA could potentially be applied to typical situations.

Bacterial succession in necrotic tissue of agria cactus (Stenocereus gummosus).

The bacterial communities associated with the development of necroses in injured agria cactus tissue were examined in the field by using both human-induced injuries and cactus tissue inoculated with cactophilic bacteria. Whole-cell bacterial fatty acids were used to determine when and where each of 23 detected species occurred. This information was then used to describe successional patterns of bacterial colonization.

Identification and ecology of bacterial communities associated with necroses of three cactus species.

To compare the bacterial communities residing in necrotic tissues of columnar cacti of the Sonoran Desert, isolates from 39 organ pipe, 19 saguaro, and 16 senita cacti were obtained. The isolates were clustered into 28 conspecific groups on the basis of their fatty acid profiles. The distributions of the individual bacterial isolates varied among cactus species.

Outcomes evaluation: measuring critical thinking.

Nursing education, along with higher education in general, is increasingly focusing on educational outcomes; critical thinking is one of these outcomes. This study examined the impact of a baccalaureate registered nurse programme on the critical thinking skills of students. Students were tested upon entry and exit of the programme and a significant (0.

Who likes hospital advertising--consumer or physician?

Both consumers and physicians have favorable attitudes toward advertising in general, but their attitudes toward hospital advertising differ considerably. In particular, the two groups differ in their opinions about the influence of advertising on hospital choice, the value of the information being advertised, and the economic impact of advertising on hospitals.

Automated situational analysis for operating room anesthesia monitoring.

The hospital operating room (OR) is an environment that requires up-to-the-minute, reliable information on a patient's state. Data is usually provided by a heterogeneous mixture of independent monitors that, due to their isolated nature, give complex and sometimes erroneous presentations of a patient's state. This complex presentation introduces the possibility of operating room personnel overlooking data items that indicate certain pending patient states, such as cardiac arrest.
