When protocols fail: technical evaluation, biomedical knowledge, and the social production of 'facts' about a telemedicine clinic.

Telecommunications systems seem to offer health care providers, professionals and patients a plethora of opportunities to respond to social and geographical inequalities in health care provision, and a new field of health care endeavor has emerged--'telemedicine'. This paper presents results from a three year ethnographic study of the development and implementation of telemedicine systems in a British region. We explore how attempts to put into service one 'telemedicine' system failed to get beyond the draft of a written protocol. Our analysis focuses on the contests between clinicians, technical experts and external evaluators over what kinds of knowledge and practice count in developing a protocol and evaluating a clinical intervention. We show how the introduction and implementation of 'hard' technologies (systems hardware) can be undermined in practice by 'soft' technologies (the practices through which evaluative knowledge is produced).

Academic and commercial development of open source applications in international health informatics. Opposite sides of the same coin?

Whilst covertly in the past many ideas developed in academic environments have made their way into commercial applications, there is growing acknowledgment that this model may be necessary for both funding academics and for project enrichment in private ventures. This paper seeks to explore and expound on the various pressures related to protocol development and the creation of a MAP (Multiphasic Algorithimic Protocol) Engine as a commercial venture based on an evolution from an academic environment, into a service oriented commercial product. It has been determined in a series of symposia that an Object Oriented; Open Source (OS) environment may best meet the needs for this endeavor. Numerous barriers and agreements remain, and explorations of these will, we believe, bring out the best of both sides of the coin - reflecting the strengths of both cultures.

Psychiatry by videophone: a trial service in north west England.

In this paper we report on the use of a video link between two general practices and a hospital based mental health team in North West England to provide a trial telepsychiatry service for individuals with depression and anxiety related disorders. Patients (n = 16) took part in an evaluation of the service by both structured questionnaire and semi-structured interview. The results of the evaluation study suggest that patients may be highly critical of telemedicine systems and that they do so not simply on the grounds of the technical quality of video links, but also because the remote link increases the difficulty that the patient faces in expressing deep scated emotional and existential problems. It is not, therefore, simply a matter of technical quality in the link, but also a question of the quality of interpersonal relations perceived by the patient.

C.A.S.M. and C.A.S.T. A new information based approach to clinical audit.

This paper outlines a research project currently being conducted at the University of Central Lancashire. The project's aims are to develop a detailed structured method for clinical audit and to construct a supporting computer based toolset to automate the process. A discussion of the background to the research and an outline of the method and toolset is portrayed.

C.A.S.M. and C.A.S.T.--phase two.

This paper outlines the second phase of a research project currently being conducted at the University of Central Lancashire. The aim of this second phase is to construct a computer based toolset for clinical audit, based on the structured method (C.A.S.M.) developed during the first phase of the project. A discussion of the validation of the C.A.S.M. and an outline of the toolset is portrayed.

High school athletes and nutritional supplements: a study of knowledge and use.

Factors influencing nutritional supplement use by high school students were assessed. Comparisons were made between various groups of sports participants and non-sports participants. The Nutritional Supplement Use and Knowledge Scale was administered to 509 students. Mean supplement use score was 10.87 (SEM = 0.50, range 0-57). Mean knowledge score was 13.56 (SEM = 0.16, range 1-21). Significant relationships (p < .01) were obtained for supplement knowledge with use, and supplement use with gender. ANOVA found significant differences between supplement use by gender (p < .01), supplement use by sports category (p < .05), and knowledge scores by sports category (p < .01). Discriminant function analysis indicated knowledge, supplement use, and subscores for protein, vitamins/minerals, knowledge, supplement use, and subscores for protein, vitamins/minerals, and carbohydrates were best discriminators of sport group membership. Greater knowledge about supplements was associated with less use; hence, education about supplements can be a deterrent to use. This study may help coaches, athletic trainers, athletic directors, teachers, physicians, and parents identify nutritional misconceptions held by adolescents.

Prevalence of adolescent health risk behaviors: school health implications.

This state survey randomly selected 2,037 ninth- and twelfth-grade students to determine the onset and prevalence of health risk behaviors. A higher pattern of risk-taking behavior was found among younger in comparison with older students. Gender differences were also noted. Implications for school health intervention are discussed.

HIV/AIDS education in Indiana public schools, grades 7-12.

Indiana secondary school principals were surveyed regarding HIV/AIDS education status in their schools. A questionnaire from the Centers for Disease Control was evaluated then modified for the survey. More than 520 school principals responded to the questionnaire mailed to all 680 school principals, grades 7-12, in Indiana. Most schools offer some form of HIV/AIDS education in grades 7-12. HIV education was taught by teachers with different educational backgrounds and school roles. Almost 60% of school principals believe students are at risk for HIV infection. Tests of statistical significance were conducted with regard to principals' opinions and actual practice of HIV/AIDS education in schools. Most schools have responded to the need for HIV/AIDS education, but with a variety of formats, teaching personnel, and teacher training.
