Identifying strategies to improve access to credible and relevant information for public health professionals: a qualitative study
Nancy R LaPelle, Roger Luckmann, E Hatheway Simpson, Elaine R Martin
BMC Public Health , 2006, DOI: 10.1186/1471-2458-6-89
Abstract: Nineteen individual interviews were conducted among employees of two domains in a state health department – communicable disease control and community health promotion. Subsequent focus groups gathered additional data on preferences for methods of information access and delivery as well as information format and content. Qualitative methods were used to identify themes in the interview and focus group transcripts.Informants expressed similar needs for improved information access including single portal access with a good search engine; automatic notification regarding newly available information; access to best practice information in many areas of interest that extend beyond biomedical subject matter; improved access to grey literature as well as to more systematic reviews, summaries, and full-text articles; better methods for indexing, filtering, and searching for information; and effective ways to archive information accessed. Informants expressed a preference for improving systems with which they were already familiar such as PubMed and listservs rather than introducing new systems of information organization and delivery. A hypothetical ideal model for information organization and delivery was developed based on informants' stated information needs and preferred means of delivery. Features of the model were endorsed by the subjects who reviewed it.Many critical information needs of PH practitioners are not being met efficiently or at all. We propose a dual strategy of: 1) promoting incremental improvements in existing information delivery systems based on the expressed preferences of the PH users of the systems and 2) the concurrent development and rigorous evaluation of new models of information organization and delivery that draw on successful resources already operating to deliver information to clinical medical practitioners.The need for improved access to high quality public health (PH) information has been echoed in various forums involving public health
The Fisher Information Matrix as a Relevant Tool for Sensor Selection in Engine Health Monitoring  [PDF]
S. Borguet,O. Léonard
International Journal of Rotating Machinery , 2008, DOI: 10.1155/2008/784749
Abstract: Engine health monitoring has been an area of intensive research for many years. Numerous methods have been developed with the goal of determining a faithful picture of the engine condition. On the other hand, the issue of sensor selection allowing an efficient diagnosis has received less attention from the community. The present contribution revisits the problem of sensor selection for engine performance monitoring within the scope of information theory. To this end, a metric that integrates the essential elements of the sensor selection problem is defined from the Fisher information matrix. An example application consisting in a commercial turbofan engine illustrates the enhancement that can be expected from a wise selection of the sensor set.
Is the Internet a useful and relevant source for health and health care information retrieval for German cardiothoracic patients? First results from a prospective survey among 255 Patients at a German cardiothoracic surgical clinic
Dietrich Stoevesandt, Claudius Diez
Journal of Cardiothoracic Surgery , 2006, DOI: 10.1186/1749-8090-1-36
Abstract: We conducted a prospective survey among 255 cardiopathic patients at a German university hospital.Forty seven respondents (18 %) used the internet and 8,8 % (n = 23) went online more than 20 hours per month. The most frequent reason for not using the internet was disinterest (52,3 %). Fourteen patients (5,4 %) searched for specific disease-related information and valued the retrieved information on an analogous scale (1 = not relevant, 5 = very relevant) on median with 4,0. Internet use is age and education dependent. Only 36 (14,1 %) respondents found the internet useful, whereas the vast majority would not use it. Electronic scheduling for ambulatory visits or postoperative telemedical monitoring were rather disapproved.We conclude that Internet use is infrequent among our study population and the search for relevant health and disease related information is not well established.Several international studies suggested that more than half and as much as 80 % of adults with Internet access use it for health care purposes [4,10,13]. These estimates have been widely distributed and now frequently form the context for discussions among the media and other of the role of the Internet in health care. Other, less well-publicized reports suggest much lower rates of Internet use [2,9]. In fact, little is known about to what extent patients in different countries access the Internet and whether they benefit from consulting it [5,8].Cardiovascular diseases are the leading cause of mortality in the industrialized world and interventional or operative procedures have been increasingly used to prevent cardiac damage. Recent innovations in cardiac surgery, e.g. minimally invasive or off-pump procedures, have significantly decreased morbidity and mortality rates among cardiopathic patients [6,17]. An increasing number of patients now undergo coronary surgery without cardiac arrest and the heart-lung-machine.Despite the recent progression and the new achievements in this field, pat
The significance of information standards for development of integrated health information system

Abstract: Information systems play a significant role in helping to improve health outcomes and decision-making at the point of care, as well as in the planning and funding of care. There is no doubt that new technologies, especially information and communication technologies, could dramatically contribute to achieve better results in our activities in general. The healthcare sector, one of the largest sectors of society accounting, is very complex with many different application requirements. There are also a number of different types of actors that need to communicate for various healthcare purposes (patients/citizens, healthcare professionals and organizations providing health care cervices, payment bodies, pharmaceutical industry, the national governments). Standardization is the first and the most important step in building an Integral Healthcare Information System. However, standardization has been recognized in most of the countries as an important tool to achieve some of the general goals in healthcare systems. The relationship between the participants locally, regionally and nationally requires that information is shared for planning, funding and treatment purposes. Health information standards are instrumental for the operation of healthcare organizations, the planning and management of the health sector, for electronic business transactions and the development of a national system of electronic health records as well. It is necessary to make relevant decisions on adoption of specific health information standards, to adjust them to local conditions as necessary, define in sufficient details methods the manner of their introduction and implementation. The successful implementation of each National Health Information Systems Strategy is heavily dependent upon the implementation of information standards.
Open Access to essential health care information
Christabel EL Stokes, Manoj Pandey
World Journal of Surgical Oncology , 2004, DOI: 10.1186/1477-7819-2-42
Abstract: 'Essential healthcare information' is the basic information required by primary health care workers to perform their role within the community. This basic information would be most useful if it is informed by relevant research, produced locally, and made available in the local language. The potential benefits of Open Access in terms of access to the research literature in general, and to research from low- and middle-income (LAMI) countries in particular, have been well described elsewhere.We would like to introduce a new dimension into this debate: Open Access has an untapped potential to enhance the synthesis and distribution of essential healthcare knowledge. Open Access, as opposed to free access, allows readers the right to use the article without restriction. Local publishers can therefore filter, reproduce and distribute the most relevant research and healthcare information from any and all Open Access journals. In essence, they can create journals focused on local issues based on content from a variety of journals. These "local journals" can be circulated in print – a medium that remains essential in countries with limited computer and Internet access. To our knowledge, this has yet to be done, although we are hoping someone will exploit this opportunity soon.In the future, we imagine the technology and infrastructure that has been developed for Open Access could be used to publish download-able manuals, guides or basic handbooks created by healthcare providers in these countries. These free resources could then be accessed worldwide and, where necessary, reproduced within local communities in the optimal medium. In an "author-pays" Open Access model the charges would be standard and could be covered by a national government organization or charity.Open Access will increase the availability of research and, in doing so, stimulate researchers in LAMI countries to develop their own research and practices. With research published in the Open Access medium it al
Locally Accessible Information and Distillation of Entanglement  [PDF]
Sibasish Ghosh,Pramod Joag,Guruprasad Kar,Samir Kunkri,Anirban Roy
Physics , 2004, DOI: 10.1103/PhysRevA.71.012321
Abstract: A new type of complementary relation is found between locally accessible information and final average entanglement for given ensemble. It is also shown that in some well known distillation protocol, this complementary relation is optimally satisfied. We discuss the interesting trade-off between locally accessible information and distillable entanglement for some states.
Integrated health care system – creating and managing
Heinz J. Janssen
Medicinski Glasnik , 2008,
Abstract: The article presents the German case of creating and managing theso called integrated health care systems. It is supposed to solve theproblem of fragmentation and lack of cooperation, which is costlyand causes difficulties to patients. The case shows that holisticthinking is better, but it requires dramatic changes in attitudes andbehavior of medical professionals and managers in both hospitalsand the government.
Signal Enhancement as Minimization of Relevant Information Loss  [PDF]
Bernhard C. Geiger,Gernot Kubin
Mathematics , 2012,
Abstract: We introduce the notion of relevant information loss for the purpose of casting the signal enhancement problem in information-theoretic terms. We show that many algorithms from machine learning can be reformulated using relevant information loss, which allows their application to the aforementioned problem. As a particular example we analyze principle component analysis for dimensionality reduction, discuss its optimality, and show that the relevant information loss can indeed vanish if the relevant information is concentrated on a lower-dimensional subspace of the input space.
Criteria for the assessment of quality of health information available online
Luisa Maria Larcher Caliri Juzzo,Maria Helena Palucci Marziale
NURE Investigación , 2005,
Abstract: Internet is creating new opportunities to improve decision-making and communications in health. Despite its obvious benefits, if no appropriate selection and evaluation of the information, the increase of the information availability could also result in many potentially harmful effects on both consumers and health professionals. Hence, they must choose appropriate resources to guide their decisions. The goal of this study is to identify through a literature review the criteria proposed by the authors to assess the quality of the information on health in web sites. The results show that, in spite of the availability of many different methods for evaluating the quality of the information about health, there are no standard criteria.
