The existence of numerous World Wide Web (WWW) sites devoted to dental education is proof that dental educators have been utilizing the pedagogical potential of information technology. Despite the availability of an immense quantity of information on the Internet, performing a search is often a complex, uncoordinated and time-consuming procedure, thus the usefulness of a guide on a topic of interest. Forty WWW sites devoted to dental education have been located using search engines. They were evaluated and classified as follows: guides, electronic publications, databases, patient education and undergraduate education; and according to subjects such as oral biology, morphology, histology, microbiology oral pathology, oral and maxillofacial surgery, radiology, periodontology, dental materials, orthodontics and neuroscience. The extensiveness and quality of some of these sites make them useful resources and knowledge banks for the teacher and the student.
The 21st century promises to usher in an era of Internet based healthcare services--Tele-Healthcare. Such services augur well with the on-going paradigm shift in healthcare delivery patterns, i.e. patient centred services as opposed to provider centred services and wellness maintenance as opposed to illness management. This paper presents a Tele-Healthcare info-structure TIDE--an 'intelligent' wellness-oriented healthcare delivery environment. TIDE incorporates two WWW-based healthcare systems: (1) AIMS (Automated Health Monitoring System) for wellness maintenance and (2) IDEAS (Illness Diagnostic & Advisory System) for illness management. Our proposal comes from an attempt to rethink the sources of possible leverage in improving healthcare; vis-à-vis the provision of a continuum of personalised home-based healthcare services that emphasise the role of the individual in self health maintenance.
Viruses have become more mobile alongside with increasing human mobility and speed of travel. At the same time we get access to information on viral outbreaks and epidemics from large parts of the world faster than ever before. Two recent epidemics will be presented to explore the value and the consequences of communicating epidemiological information through the Internet. The epidemiology, clinical features, diagnostic procedures and prophylaxis of imported viral infections are presented. Risk factors for the emergence and resurgence of viral diseases are being discussed.
The healthcare enterprise requires a great deal of knowledge to maintain premium efficiency in the delivery of quality healthcare. We employ Knowledge Management based knowledge acquisition strategies to procure 'tacit' healthcare knowledge from experienced healthcare practitioners. Situational, problem-specific Scenarios are proposed as viable knowledge acquisition and representation constructs. We present a healthcare Tacit Knowledge Acquisition Info-structure (TKAI) that allows remote healthcare practitioners to record their tacit knowledge. TKAI employs (a) ontologies for standardisation of tacit knowledge and (b) XML to represent scenario instances for their transfer over the Internet to the server-side Scenario-Base and for the global sharing of acquired tacit healthcare knowledge.
Easier and focused access to healthcare information can empower individuals to make 'informed' choices and judgements about personal health maintenance. To achieve 'optimum' patient empowerment, we need to re-evaluate and potentially re-design the processes of healthcare information delivery. Our suggestion is that healthcare information should be personalised according to each individual's healthcare needs and it should be pro-actively delivered, i.e. pushed towards the individual. We present an intelligent Personalised Healthcare Information Delivery Systems that aims to enhance patient empowerment by pro-actively pushing customised, based on one's Electronic Medical Record, health maintenance information via the WWW.
In 1999, the Department of Social and Preventive Medicine set up its website on the Internet (http://ummc.med.uni.edu.my/sps/. Setting up the website was a whole new experience for the author and many new things were learnt along the way. This paper describes how the website was constructed, the problems, and solutions to all these problems. The experience of the author in setting up the SPM website may be useful to others wishing to set up their own department websites. KEYWORDS: Internet, SPM, website, web page

This paper describes the ideOll behind the migration process, the reason (or the migration, problems and solutions 10 aU these problems as well as the benefits derived from the migration. The experience of this process m~y be useful to others wishing 10 improve IT facilities without resorting to expensive solutions. KEYWORDS: Internet, leased line, migration
Worldwide healthcare delivery trends are undergoing a subtle paradigm shift--patient centered services as opposed to provider centered services and wellness maintenance as opposed to illness management. In this paper we present a Tele-Healthcare project TIDE--Tele-Healthcare Information and Diagnostic Environment. TIDE manifests an 'intelligent' healthcare environment that aims to ensure lifelong coverage of person-specific health maintenance decision-support services--i.e., both wellness maintenance and illness management services--ubiquitously available via the Internet/WWW. Taking on an all-encompassing health maintenance role--spanning from wellness to illness issues--the functionality of TIDE involves the generation and delivery of (a) Personalized, Pro-active, Persistent, Perpetual, and Present wellness maintenance services, and (b) remote diagnostic services for managing noncritical illnesses. Technically, TIDE is an amalgamation of diverse computer technologies--Artificial Intelligence, Internet, Multimedia, Databases, and Medical Informatics--to implement a sophisticated healthcare delivery infostructure.
We developed a personal blood pressure monitoring system for patients with hypertension or hypotension. The system can be used to measure a patient's blood pressure at home and to transmit the data automatically to a hospital database via the Internet. The accuracy of blood pressure readings using the system was assessed by comparison with readings from a standard digital sphygmomanometer in four subjects. The measurement error for the systolic readings was 1.7-2.7% and for the diastolic readings 2.7-3.2%. The system therefore appears to be a promising means of assessing blood pressure remotely.
We present an Internet-based Personalised Healthcare Information (PHI) dissemination system. Information personalisation is guided by the individual's current health profile as recorded in his/her EMR. A PHI package is composed by intelligently selecting and synthesizing various topic-specific documents, each corresponding to some health parameter noted in the EMR. To ensure medical consistency, constraint satisfaction techniques are employed during the information selection phase. The resultant PHI package--covering both long-term and immediate health-maintenance requirements--can be pro-actively pushed to the individual via email, thereby ensuring the timely availability of situation-specific health maintenance information. The featured work is in line with the Malaysian Multimedia Super Corridor Telemedicine initiative and can serve as a test-bed to evaluate the effectiveness of PHI, system design and operational considerations for larger-scale deployment.
Development and usage of Case Based Reasoning (CBR) driven medical diagnostic system requires a large volume of clinical cases that depict the problem-solving methodology of medical experts. Successful usage of CBR based systems in healthcare is constrained by the need for a continuous supply of current and correct clinical cases (in an electronic medium) from medical experts. To address this constraint we present a strategy to pro-actively transform generic Electronic Patient Records (EPR) to Operable CBR-oriented Cases (OCC) that are compliant to specialised CBR-based medical systems. EPR-OCC transformation methodology is based on XML parse-trees, Unified Medical Language Source (UMLS) meta-thesauri and medical knowledge ontologies. The featured work involves the implementation of a Java-based computer system for the automatic transformation of XML-based EPR-originating from heterogeneous EPR repositories accessible over the Internet/WWW-to specialised OCC that can then be seamlessly incorporated within Intelligent CBR-based Medical Diagnostic Systems.
Initiatives in healthcare knowledge management have provided some interesting solutions for the implementation of large-scale information repositories vis-à-vis the implementation of Healthcare Enterprise Memories (HEM). In this paper, we present an agent-based Intelligent Healthcare Information Assistant (IHIA) for dynamic information gathering, filtering and adaptation from a HEM comprising an amalgamation of (i) databases storing empirical knowledge, (ii) case-bases storing experiential knowledge, (iii) scenario-bases storing tacit knowledge and (iv) document-bases storing explicit knowledge. The featured work leverages intelligent agents and medical ontologies for autonomous HEM-wide navigation, approximate content matching, inter- and intra-repositories content correlation and information adaptation to meet the user's information request. We anticipate that the use of IHIA will empower healthcare stakeholders to actively communicate with an 'information/knowledge-rich' HEM and will be able to retrieve with ease 'useful' task-specific information via the presentation of cognitively intuitive queries.
Medical physics is a relatively small community but it spans great geographical distances, usually with a scarcity of experts whose expertise could greatly benefit students entering into the field. In addition there are many software systems for which an interactive education method would be most advantageous.
A cross-sectional study of medical students using a self-administered questionnaire was carried out in the Faculty of Medicine, University of Malaya, Malaysia from December 2000 to January 2001 to determine IT usage, perceptions and literacy of medical students. 366 of 653 (56.0%) students reported owning some type of personal computer. Students mainly used the computer to get onto the Internet, do word-processing and make presentations. Junior (Year One and Two) students and those who had used computers before entering university were more likely to use the Internet. Those who own computers were more likely to feel comfortable with software (OR 1.61, 95% CI: 1.09, 2.38). Students who use the Internet were more likely to perceive that IT facilitated their studies (OR 4.61, 95% CI: 2.35, 9.05). The highest self-reported IT skill was e-mailing followed by surfing the World Wide Web and word-processing. Male students and junior students had significantly higher self-reported IT literacy scores compared to female students and senior students. Significant predictors for an IT identifier score after adjusting for other variables were self-reported rating of computer knowledge, number of siblings, parents' income and gender.
Existing Problem-Based Learning (PBL) problems, though suitable in their own right for teaching purposes, are limited in their potential to evolve by themselves and to create new knowledge. Presently, they are based on textbook examples of past cases and/or cases that have been transcribed by a clinician. In this paper, we present (a) a tacit healthcare knowledge representation formalism called Healthcare Scenarios, (b) the relevance of healthcare scenarios in PBL in healthcare and medicine, (c) a novel PBL-Scenario-based tacit knowledge explication strategy and (d) an online PBL Problem Composer and Presenter (PBL-Online) to facilitate the acquisition and utilisation of expert-quality tacit healthcare knowledge to enrich online PBL. We employ a confluence of healthcare knowledge management tools and Internet technologies to bring tacit healthcare knowledge-enriched PBL to a global and yet more accessible level.
The need to deliver teaching material in medical education using the internet is compelling in view of the many advantages that the internet provides. The internet has enabled organizations, in particular institutions of higher education to conduct various courses entirely electronically and without regard to physical geographical boundaries. The term CAL is used to denote the employment of the Internet for the delivery of teaching material, conduct of discussion, as;sessment of performance and interaction between students and teachers. This study reviews reports of the use and evaluation of Computer-Aided-Learning (CAL) in teaching various major disciplines in medicine.
Attempts in current health care practice to make health care more accessible, effective, and efficient through the use of information technology could include implementation of computer-based dietary menu generation. While several of such systems already exist, their focus is mainly to assist healthy individuals calculate their calorie intake and to help monitor the selection of menus based upon a prespecified calorie value. Although these prove to be helpful in some ways, they are not suitable for monitoring, planning, and managing patients' dietary needs and requirements. This paper presents a Web-based application that simulates the process of menu suggestions according to a standard practice employed by dietitians.
Malaysia's experience in implementing the Integrated Telehealth Project has placed her way ahead in the arena of world Telehealth. Thus, she has become the focus point, reference point and benchmark for similar endeavors around the world. In fact, it would not be presumptuous to state that the Integrated Telehealth project is a trail-blazing pioneer with e-leadership experience and skills developed over the last few years. It is hoped that the Integrated Telehealth concept will find acceptance and credence globally.
This paper attempts to sensitize the participants to understand the benefits of looking at the regulations of accreditation for medical courses in the neighbouring nearby countries. Deregulation of Medical Education like what they have done will bring enormous revenue benefits for the existing assets like the airports, hospitals, hotels resorts and the communication infrastructure of Malaysia.
