Intranet usage and potential in acute care hospitals in the United States: survey-2000.

This paper provides the results of the Survey-2000 measuring Intranet and its potential in health care. The survey measured the levels of Internet and Intranet existence and usage in acute care hospitals. Business-to-business electronic commerce and electronic commerce for customers were measured. Since the Intranet was not studied in survey-1997, no comparisons could be made. Therefore the results were presented and discussed. The Intranet data were compared with the Internet data and statistically significant differences were presented and analyzed. This information will assist hospitals to plan Internet and Intranet technology. This is the third of three articles based upon the results of the Survey-2000. Readers are referred to prior articles by the author, which discusses the survey design and provides a tutorial on technology transfer in acute care hospitals.(1) The first article based upon the survey results discusses technology transfer, system design approaches, user involvement, and decision-making purposes. (2) The second article based upon the survey results discusses distribution of Internet usage and rating of Internet usage applied to specific applications.

Bifonazole, but not the structurally-related clotrimazole, induces both peroxisome proliferation and members of the cytochrome P4504A sub-family in rat liver.

Male Wistar rats were treated with a low (150 mumol/kg) and a high (750 mumol/kg) dose of either clotrimazole of bifonazole. Bifonazole, but not clotrimazole, exhibited the characteristics of a peroxisome proliferator including hepatomegaly (increase in liver:body weight ratio), up to a 4-fold induction of lauric acid omega-hydroxylase activity and an 8-fold induction of palmitoyl-CoA oxidation by rat liver peroxisomes. This induction of enzyme activities was paralleled by increased protein levels as determined by immunochemical analysis for both liver microsomal cytochrome P4504A1 and the peroxisomal trifunctional protein of the beta-oxidation spiral. In contrast, clotrimazole did not increase protein levels of either cytochrome P4504A or the trifunctional protein. Western blot analyses demonstrated that bifonazole also induced P4502B1/2B2, P4503A and P4501A1, but not P4502E1. Clotrimazole induced a similar spectrum of P450s as determined by Western blotting with the exception that this azole was a marginal P4501A1 inducer under the conditions studied. Taken collectively, our data provides evidence that bifonazole is one of the increasingly recognised, non-carboxylate containing xenobiotics that induce both peroxisome proliferation and the cytochrome P4504A sub-family in rat liver.

Comparative induction of cytochrome P4504A in rat hepatocyte culture by the peroxisome proliferators, bifonazole and clofibrate.

1. The influence of imidazole and triazole antifungal drugs on cytochrome P450 levels in male Wistar primary rat hepatocyte culture for 70 h has been investigated and compared with clofibrate. 2. Bifonazole, clotrimazole, geniconazole clofibrate induced total P450 in hepatocytes, whereas itraconazole, miconazole and UK-47,265 did not. 3. When the CYP4A subfamily was examined, only bifonazole and clofibrate induced CYP4A as assessed by both Western blot analysis and the 11- and 12-hydroxylation of lauric acid. 4. By analysis of concentration-response curves in hepatocyte culture, bifonazole was 160 and 40 times more potent than clofibrate for induction of the 11- and 12-hydroxylation of lauric acid respectively. 5. Taken collectively, our data have identified bifonazole as a relatively potent, non-carboxylate inducer of CYP4A and the mechanism of induction and specificity of this azole is discussed.

Voting and priorities in health care decision making, portrayed through a group decision support system, using analytic hierarchy process.

Within the health care industry many decision making approaches and tools are used. This paper explores a new tool, the Analytic Hierarchy Process (AHP), which permits both subjective and objective information to be considered in a decision. AHP has tremendous potential to solve both traditional and non-traditional health care problems. Its strength as a decision-making tool is its ability to combine both subjective and objective data. Application of AHP is discussed within the context of a Group Decision Support System (GDSS) model developed by Hatcher. The model is reviewed in limited detail, and readers are referred to the original article that defined and discussed the uniqueness and level of sophistication of GDSS applications in the health care industry. Health and medical delivery problems are discussed to highlight AHP requirements and the complexity of AHP applications. Health care applications are unique in that they lend themselves ideally to the use of computer data, image, voice, text, and multimedia concepts.

Uniqueness of Group Decision Support Systems (GDSS) in medical and health applications.

Group Decision Support Systems (GDSS) are defined and discussed. A GDSS model developed by the author is reviewed in depth for communication of the concepts of GDSS. The model's components are related to health care applications. Questions about unique requirements and level of sophistication in health care applications are explored. What are the differences? What is needed in GDSS software? How do implementation strategies differ? The purpose of this paper is to define and discuss the uniqueness and level of sophistication of GDSS applications in health care. The information requirements and level of information abstraction are the major forces considered in the design of specific medical GDSSs. Data for the GDSS and queries originate both internally and externally to the system. Raw data may be in image form and require extensive analysis by the decision makers for information to be extracted from the raw data. Efforts also are made to relate financial and medical data for better business decisions. This integration often has limited success. Additionally, financial data represent multiple sources and present concerns of validity and reliability. In medical diagnoses the knowledge bases are large and contain thousands of rules. Treatment planning and progress reporting rely on medical records that contain thousands of information items and that often require interpretation by an expert. These information attributes go beyond qualitative versus quantitative definitions and are the author's basis for the analysis presented in this paper.

A simulation based decision support system for a health promotion center.

This study represents the financial and qualitative evaluation of a Health Promotion Center of a private hospital located in a medium-sized town located in a predominantly agricultural area. The major objective of this study was to evaluate the impact of various pricing, advertising, and service strategies on profitability. The result is a pricing strategy which allows the center to reach their financial goal of breaking even while maintaining their service policies. The hospital, which serves a community of 500,000 people, recently developed a new concept called a "Health Promotion Center" (HPC). The HPC provides services such as fitness programs, nutrition awareness, rehabilitation and therapy, and child and adult care. For this purpose, a new building was constructed and the center became operational in June 1983. A variety of management options available to the center are described with evaluations of their usefulness. Evaluation methods include scenarios, stochastic simulations, and analyses of how the decision makers use these methods. The inclusion of risk management, model flexibility, and user involvement are stressed throughout the paper and are critical in the decision process.
