Introducing hypertext in primary health care: a study on the feasibility of decision support for practitioners.
A study on the feasibility of the introduction of hypertext systems for communication of medical knowledge in primary care is described. Shortliffe's constraints on areas for application of decision support are evaluated (i.e., theoretical barriers, observable and recognized needs among users, sources of usable knowledge, available system development method). Considering the barriers derived from the knowledge types and forms used by practitioners, hypertext was found suitable as support at 'breakdowns' in practice routines, to generate 'alarms', as well as for continued medical education. A survey of the a priori acceptance of decision support systems by general practitioners showed that 84% would use the computer support if it was available today and that full-text databases, such as hypertext, were given highest priority for introduction. Local specialist physicians were identified as knowledge sources for therapy advice. Implementation of prototype systems envisioned use of hypertext in primary care as the introduction of a communication medium for co-operative health care decision making. A model for the introduction into the work environment is described.

Information needs in office practice: are they being met?
We studied the self-reported information needs of 47 physicians during a half day of typical office practice. The physicians raised 269 questions about patient management. Questions related to all medical specialties and were highly specific to the individual patient's problem. Subspecialists most frequently asked questions related to other subspecialties. Only 30% of physicians' information needs were met during the patient visit, usually by another physician or other health professional. Reasons print sources were not used included the age of textbooks in the office, poor organization of journal articles, inadequate indexing of books and drug information sources, lack of knowledge of an appropriate source, and the time required to find the desired information. Better methods are needed to provide answers to questions that arise in office practice.

A poison education program for primary school.
A program with which to teach children in grades 1 and 2 to identify poisons and hazard symbols, to learn where poisons should be stored and to recognize a poisoning and contact a poison control center in the event of a poisoning was developed. Each objective was taught in one 30-minute lesson by the children's school teachers. Evaluation of the approximately 400 children who received the program by pre- and post-tests demonstrated that they learned to identify poisons, to recognize hazard symbols and the telephone number of the local poison control center. The children were also asked to identify their source of knowledge about poisons and cited parents, television and school as their most important sources.

Nursing practice. Developing a philosophy.
The application of nursing models has been a recent theme in British nursing. Part of this process is the development of a nursing philosophy which underpins the model. Nurses at clinical level are often required to define their philosophy to meet clinical, educational and managerial objectives. The first part of this two-part article explores the significance of nursing philosophy to practice. In the second part, a case study is used to illustrate how clinical nurses can set about defining a philosophy of nursing for themselves. Dickoff et al (1) indicate that a philosophy is significant in the generation of theory. By identifying the nature of practice, theoretical relationships become apparent. It is also significant as Johnson (2) states in nursing's development as a profession. Johnson further asserts that nurses should use their beliefs to build a conceptual system of the person to be served and an abstract model for practice which allows such purpose to be fulfilled. However a nurse's beliefs and values about nursing may have no theoretical substance to them. They may be purely intuitive in nature. Writing a philosophy legitimates intuition. Kitson (3) considers that nurse theorists who believe that only developing a knowledge base through a scientific approach are at risk of throwing away the intuitive sources of knowledge within nursing. Yet gut reactions have been shown to be critical in the development of excellence in nursing (4). Kitson believes that intuitions can lead to developing 'grassroots standards of care' and a clearer definition of what nursing is.(ABSTRACT TRUNCATED AT 250 WORDS)

Knowledge about and attitudes toward genetic screening among high-school students: the Tay-Sachs experience.
High school students (ages 15 to 18 years; No. = 930) taking biology in their curriculum were surveyed (the first survey), in the classroom, for their knowledge and attitudes about Tay-Sachs disease and other "public" issues in genetics. High-school students now constitute 38.9% of those screened for the Tay-Sachs gene in the Montreal program and the participation rate is 75% among eligible Jewish students. Knowledge and attitudes about the screening experience were also surveyed (the second survey) in a sample (No. = 120) containing equal numbers of carriers and noncarriers matched for sex and age. The response rate was 75% in the second survey. The first survey revealed that the level of knowledge about Tay-Sachs disease is high among students, only 28% percent of whom were Jewish. Students have a very positive attitude toward genetic screening in general. These findings are associated with an effort to expand the human genetics content in the biology curriculum. The second survey revealed a favorable attitude toward the screening experience and the self-knowledge obtained among screened students. The screening clinic in the schools, and literature provided by the screening authority, was an effective source of knowledge about the significance of Tay-Sachs heterozygosity. Carriers experienced initial anxiety; later attitudes were similar in carrier and noncarriers. Self-image was unchanged in 90% and diminished in 10% of carriers and enhanced in 10% of noncarriers. Heterozygous students perceive information about their genetic status as useful to themselves and 95% want to know the gennotype of an intended spouse; 88.4% would marry a carrier and only 11.6% would "reconsider." These findings encourage us to emphasise high-school screening as the preferred program in our community and to offer it as an effective aid to the physician faced with increasing demands in medical genetics. It is also an effective model for teaching some genetics and human biology in the schools.

Community complexity and knowledge of facilities.
This research examines the relationships among three sets of variables: the amount of differentiation (or complexity) of a community, individual characteristics of its residents, and residents' knowledge of available facilities. A sample of 144 communities in upstate New York was drawn. Community differentiation was measured by means of the Medical Specialties Scale. A subsample of 32 communities was drawn, and in each of these a random sample of 40 noninstitutionalized men and women was interviewed. Multiple regression analysis was the statistical procedure used to test the hypothesis of the study. The findings uncovered an interaction effect, i.e., the relationship between community complexity and knowledge is different within different categories of communities. There is a negative relationship between community complexity and knowledge of facilities for rural communities, but for large cities the relationship is positive. The findings are interpreted as resulting from different sources of knowledge in different types of communities.

Public knowledge of hospices: a street survey in Glasgow.
A street survey was conducted in Glasgow to find out the level of public knowledge of and attitudes to hospices generally and two local hospices. The level of knowledge was not high, though attitudes to hospices were positive. Those few respondents with unfavourable attitudes had little knowledge of hospices generally and knew little about the local hospices. The factors associated with level of knowledge and attitudes were different for the two local hospices. The media and the collection of money for hospices were the main source of knowledge.

Commentary: Patient package inserts. I. Nature, notions, and needs.
A total of 137 completed questionnaires were obtained from several population samples in an attempt to assess drug knowledge, information sources, and views on drug information with particular attention to the possible role of a patient-oriented package insert. The results indicated that the study population was variably informed and could make fairly accurate assessments by this knowledge. Responders placed great importance on the doctor and pharmacist as preferred and actual drug information sources. The mass media were accorded little prominence. Great emphasis was placed on the adequate provision of information, and this appears to be a crucial function in an adequate doctor-patient relationship. The results appear to indicate a favorable climate for establishing a patient-oriented package insert that should have summarized as well as detailed information to complement the doctor and pharmacist as primary information sources.

[Methods of toxicologic evaluation--possibilities and limits].
Toxicological knowledge is founded on observation in humans consisting of casuistic presentations and epidemiologic research and on animal experiments. The possibilities and limitations of these sources of knowledge are presented with special reference to the problems of the dose and of toxic interactions. The limitations of toxicological knowledge primarily result from the impossibility to prove "no action". Therefore, it is not possible to prove the absolute safety of a substance but only the acceptability by assessing its advantages and risks.

Adolescents' communication styles and learning about birth control.
Adolescents have different communication styles for acquiring information about birth control from a mass medium--interactant or noninteractant, depending on whether they involve communication with others in the process of media use. Three interactant styles are identified: a home-oriented style, where communication is primarily with immediate members and friends; a peer-oriented style, where communication is primarily with own-age peers and personal friends; and multi-source user, where communication is with more than one cluster of sources and the majority of one's communication is not with any particular source. The noninteractant style identified is a media-oriented style, where the adolescent relies exclusively on the mass media for information acquisition without communicating with anyone about the content or process of learning. Data suggest that the interactant style, especially for the multi-source user, is most beneficial for new learning. Gender and the presence of siblings at home are important moderators of the relationship between communication styles and knowledge of birth control. For example, females with a media-oriented style know more about birth control than females with a home-oriented style. Implications of the findings for the delivery of birth control information to adolescents are discussed.

A knowledge-based architecture for protein sequence analysis and structure prediction.
Methods for analyzing the amino-acid sequence of a protein for the purposes of predicting its three-dimensional structure were systematically analyzed using knowledge engineering techniques. The resulting entities (data) and relations (processing methods and constraints) have been represented within a generalized dependency network consisting of 29 nodes and over 100 links. It is argued that such a representation meets the requirements of knowledge-based systems in molecular biology. This network is used as the architecture for a prototype knowledge-based system that simulates logically the processes used in protein structure prediction. Although developed specifically for applications in protein structure prediction, the network architecture provides a strategy for tackling the general problem of orchestrating and integrating the diverse sources of knowledge that are characteristic of many areas of science.

The perception of fluent speech.
The perception of fluent speech involves both acoustic-driven and knowledge-driven sources of information. Acoustic sources that directly convey information about higher-order linguistic characteristics include the suprasegmental aspects of speech, associated with the acoustic cues of fundamental frequency, duration, and intensity. From the standpoint of cochlear prostheses, interest in listeners' perception of these suprasegmentals is heightened by the fact that these properties are typically among the best preserved sources of speech information in the sensorineural hearing-impaired. Studies with normal listeners indicate that suprasegmentals provide cues to such linguistic factors as word stress, syntactic structure, and semantic interpretation. In addition, they supply information about many nonlinguistic characteristics of the speaker. Research on knowledge-driven processes indicates that normal listeners utilize knowledge of lexical, syntactic, and semantic constraints of the language to guide the segmentation of speech into word-like units and to select among candidate word choices. These findings are related to research with hearing-impaired listeners and prosthesis testing.

An analysis of the concept of self-neglect.
A dimension of self-care that has rarely been studied but that nonetheless poses serious problems for efforts to enhance health is self-neglect. Self-neglect here refers to clients who display a pattern of intentionally neglecting prescribed self-care activities despite available resources and knowledge. This article presents the results of a concept analysis of self-neglect as a first step toward further theory development, research, and eventual practical applications. The literature review addresses suicidology and noncompliance as areas significant to analysis of the concept. Ethical, personal, and esthetic as well as empirical sources of knowledge are included as relevant to the conceptualization of self-neglect. Several case examples are constructed to distinguish self-neglect from other health-related behaviors that are potentially harmful. Measures designed to address the complexity of the concept are outlined as the empirical referents. It is concluded that the concept analysis of self-neglect can help to extricate nurse theoreticians and clinicians from conceptual ruts so that new answers to old but challenging problems related to self-care will be discovered.

Study of the opinion and level of knowledge about AIDS problem among secondary school students and teachers in Alexandria.
The level of knowledge and the opinion about HIV/AIDS problem of 571 students (179 females, 392 males) and 211 teachers (85 females, 126 males) were assessed using an interview-questionnaire. The results explored the little priority given to sex education in Egyptian schools in addition to the very minor role of schools as source of knowledge (about AIDS problem) for students and teachers who revealed much interest towards the problem and wanted to know more about it, reflecting the need for urgent organized health educational programme.

Medical ethics, moral philosophy and moral tradition.
Medical ethics is commonly assumed to be a form of 'applied moral philosophy' in which practical moral judgments are deduced from moral theories. This account of the relationship between moral theory and moral judgment is inadequate in several reports. The deductivist approach often results in inadequate attention being given to social, historical and developmental contexts. It also fails to explain some common phenomena in practical moral reasoning. In contrast to the emphasis in deductivism, a case-centered or casuistic practical ethics insists on immersion in the particularities of cases and on interpretation of details in light of moral maxims and other mid-level forms of moral reasoning. Two features of casuistics that ought to be distinguished but frequently are not, are: (1) the emphasis on immersion and interpretation, and (2) a claim about the relation between moral judgment and moral theory as sources of moral knowledge. Once we consider case-centered moral judgments as sources of moral knowledge, we must also begin to look critically but open-mindedly to moral traditions which, upon examination, appear to be more dynamic and to have more reformist potential than is commonly assumed.

[A preliminary study of the factors which lead to patient readmission in psychiatric hospitals].
The readmission of patients to psychiatric hospitals is preoccupying. This occurrence led us to this study which has as objective the identification of the determinant factors of the readmission; the nurse's opinion of what can be done to attenuate and the source of knowledge on the topic. The date collection was carried out with twenty three nurses of three countries: Peru (7), Brazil (9) and Colombia (7). The following factors were evidenced: social-economical, lack of orientation of family members and patient and institutional policy. Activities mentioned were actions directed toward working with families and patients, team work and community work. The sources of information most frequently mentioned were daily practice, reading and events. Some differences were evidenced among the three countries.
