Pathology informatics questions and answers from the University of Pittsburgh pathology residency informatics rotation.

CONTEXT: Effective pathology practice increasingly requires familiarity with concepts in medical informatics that may cover a broad range of topics, for example, traditional clinical information systems, desktop and Internet computer applications, and effective protocols for computer security. To address this need, the University of Pittsburgh (Pittsburgh, Pa) includes a full-time, 3-week rotation in pathology informatics as a required component of pathology residency training. OBJECTIVE: To teach pathology residents general informatics concepts important in pathology practice. DESIGN: We assess the efficacy of the rotation in communicating these concepts using a short-answer examination administered at the end of the rotation. Because the increasing use of computers and the Internet in education and general communications prior to residency training has the potential to communicate key concepts that might not need additional coverage in the rotation, we have also evaluated incoming residents' informatics knowledge using a similar pretest. DATA SOURCES: This article lists 128 questions that cover a range of topics in pathology informatics at a level appropriate for residency training. These questions were used for pretests and posttests in the pathology informatics rotation in the Pathology Residency Program at the University of Pittsburgh for the years 2000 through 2002. With slight modification, the questions are organized here into 15 topic categories within pathology informatics. The answers provided are brief and are meant to orient the reader to the question and suggest the level of detail appropriate in an answer from a pathology resident. RESULTS: A previously published evaluation of the test results revealed that pretest scores did not increase during the 3-year evaluation period, and self-assessed computer skill level correlated with pretest scores, but all pretest scores were low. Posttest scores increased substantially, and posttest scores did not correlate with the self-assessed computer skill level recorded at pretest time. CONCLUSIONS: Even residents who rated themselves high in computer skills lacked many concepts important in pathology informatics, and posttest scores showed that residents with both high and low self-assessed skill levels learned pathology informatics concepts effectively.

The computerized patient record: where do we stand ?

OBJECTIVES: To provide an overview of trends in research, developments and implementations of the computerized patient record (CPR) of the last two years. METHODS: We surveyed the medical informatics literature, spanning the years 2004-2005, focusing on publications on CPRs. RESULTS: The main trends revealed were: 1) the development of technologies to realize privacy and security goals or remote data entry and access to CPRs; 2) investigations into how to enhance the quality and reuse of CPR data; 3) the development and evaluation of decision support functions to be integrated with CPRs; 4) evaluations of the impact of CPRs on clinicians, patients, clinical work settings and patient outcomes; and 5) the further development and use of standards to move towards shared electronic health records (EHRs). CONCLUSION: The CPR is playing a growing part in medical informatics research and evaluation studies, but the goal of establishing a comprehensive lifelong EHR is still a long way off. In moving forward to EHRs, convergence of EHR standards seems required to realize true interoperability of health care applications. User acceptance of present-day CPRs (for all categories of users) and compatibility with work patterns has not been achieved yet, and can only be realized by giving these goals high priority. This will require substantial resources for in-depth work flow analysis, development and evaluation of CPRs. Besides this, the implementation of effective CPRs asks for health care organizations that are willing to invest in new developments and to contribute to evaluation studies, to further improve CPRs' functionalities and enhance their use in practice.

Medical privacy protection based on granular computing.

Based on granular computing methodology, we propose two criteria to quantitatively measure privacy invasion. The total cost criterion measures the effort needed for a data recipient to find private information. The average benefit criterion measures the benefit a data recipient obtains when he received the released data. These two criteria remedy the inadequacy of the deterministic privacy formulation proposed in Proceedings of Asia Pacific Medical Informatics Conference, 2000; Int J Med Inform 2003;71:17-23. Granular computing methodology provides a unified framework for these quantitative measurements and previous bin size and logical approaches. These two new criteria are implemented in a prototype system Cellsecu 2.0. Preliminary system performance evaluation is conducted and reviewed.

Radiology speech recognition: workflow, integration, and productivity issues.

Continuous voice recognition is now a reality, with at least 3 major vendors providing independent systems for radiology departments. However, to be truly useful, such systems must be integrated into the overall medical informatics architecture including order entry into the radiology information system, the ability to receive orders from the radiology information system, acceptance and transcription of dictation, and transmission of validated reports to the hospital information system (HIS)for billing capture. In addition, the system should permit sufficient flexibility to permit radiologists to operate in multiple modes: real-time recognition, batch processing, or spooling of audio files for later transcription by human agents, which is especially useful for very difficult accents. This article demonstrates the various modes of operation for 2 recognition systems that have been used in our center, describes the basics of their recognition models, examines the HL7 messages required for medical informatics integration, and finally illustrates the effect on report turnaround times.

Standards to support development of terminological systems for healthcare telematics.

The Technical Committee on "Medical Informatics" of the European Committee for Standardization (CEN/TC251) is supporting developers of terminological systems in healthcare by a series of standards. The dream of "universal" coding system was abandoned in favor of a coherent family of terminologies, diversified according to tasks; two ideas were introduced: (1) the "categorical structure", i.e. a model of semantic categories and their relations within a subject field and (2) the "cross-thesaurus", i.e. a system of descriptors to build a systematic representation (called here "dissection") for each terminological phrase, coherent across diverse terminologies on a given subject field. The goal is to assure coexistence and interoperability (and reciprocal support for development and maintenance) to three generations of systems: (1) traditional paper-based systems (first generation); (2) compositional systems built according to a categorical structure and a cross-thesaurus (second generation) and (3) formal models (third generation). Various scenarios are presented, on the exploitation of computer-based terminological systems. The idea of "operational meaning" of terminological phrases within administrative and organizational contexts and the idea of "task-oriented details" are also introduced, to justify and exploit design constraints on terminological systems.

Factors and forces affecting EHR system adoption: report of a 2004 ACMI discussion.

After the first session of the American College of Medical Informatics 2004 retreat, during which the history of electronic health records was reviewed, the second session served as a forum for discussion about the state of the art of EHR adoption. Adoption and diffusion rates for both inpatient and outpatient EHRs are low for a myriad of reasons ranging from personal physician concerns about workflow to broad environmental issues. Initial recommendations for addressing these issues include providing communication and education to both providers and consumers and alignment of incentives for clinicians.

Scalable software architectures for decision support.

Interest in decision-support programs for clinical medicine soared in the 1970s. Since that time, workers in medical informatics have been particularly attracted to rule-based systems as a means of providing clinical decision support. Although developers have built many successful applications using production rules, they also have discovered that creation and maintenance of large rule bases is quite problematic. In the 1980s, several groups of investigators began to explore alternative programming abstractions that can be used to build decision-support systems. As a result, the notions of "generic tasks" and of reusable problem-solving methods became extremely influential. By the 1990s, academic centers were experimenting with architectures for intelligent systems based on two classes of reusable components: (1) problem-solving methods--domain-independent algorithms for automating stereotypical tasks--and (2) domain ontologies that captured the essential concepts (and relationships among those concepts) in particular application areas. This paper highlights how developers can construct large, maintainable decision-support systems using these kinds of building blocks. The creation of domain ontologies and problem-solving methods is the fundamental end product of basic research in medical informatics. Consequently, these concepts need more attention by our scientific community.

Selected eHealth applications in Cyprus from the training perspective.

OBJECTIVES: In this paper a review of selected eHealth applications in Cyprus is presented linked with their success or failure based on their training activities. METHODS: The eHealth systems presented and their training activities include an update of the health information system (HIS) in the public hospitals, a medical system for emergency telemedicine (AMBULANCE and EMERGENCY-112 projects), a home monitoring system for cancer patients (DITIS), a satellite-based network in healthcare applications (EMISPHER and HEALTHWARE projects), and the training activities of the Cyprus Society of Medical Informatics. Different methodologies for training were used ranging from classical approaches like train the trainers, using demo cases followed by personal training, group training, and workshops, to more recent methodologies based on eLearning sessions including teleconsultations. RESULTS: The training was carried out successfully in all cases. However, not all eHealth systems were put into practice successfully, mainly for reasons not related to training. CONCLUSIONS: It is anticipated that this paper will promote the importance of these applications and their training activities as well as help in the spin off of others thus enabling the offering of a better service to the citizen.

Multimedia technologies in education.

In general multimedia is the combination of visual and audio representations. These representations could include elements of texts, graphic arts, sound, animation, and video. However, multimedia is restricted in such systems where information is digitalized and is processed by a computer. Interactive multimedia and hypermedia consist of multimedia applications that the user has more active role. Education is perhaps the most useful destination for multimedia and the place where multimedia has the most effective applications, as it enriches the learning process. Multimedia both in nursing education and in medical informatics education has several applications as well. A multimedia project can be developed even as a "stand alone" application (on CD-ROM), or on World Wide Web pages on Internet. However several technical constraints exist for developing multimedia applications on Internet. For developing multimedia projects we need hardware and software, talent and skill. The software requirements for multimedia development consist of one or more authoring systems and various editing applications for text, images, sounds and video. In this chapter different software tools for creating multimedia applications are presented. In the last part of this chapter, two examples of multimedia educational training programs are discussed. Both are "stand alone" applications (CD-ROMs). The first, examines several aspects of the electronic patient record by using videos, audio descriptions, lectures and glossary, while the second one presents several topics regarding epidemiology and epidemiological research by using graphics, sound and animation.

osni.info-Using free/libre/open source software to build a virtual international community for open source nursing informatics.

Many health informatics organizations seem to be slow to take up the advantages of dynamic, web-based technologies for providing services to, and interaction with, their members; these are often the very technologies they promote for use within healthcare environments. This paper aims to introduce some of the many free/libre/open source (FLOSS) applications that are now available to develop interactive websites and dynamic online communities as part of the structure of health informatics organizations, and to show how the Open Source Nursing Informatics Working Group (OSNI) of the special interest group in nursing informatics of the International Medical Informatics Association (IMIA-NI) is using some of these tools to develop an online community of nurse informaticians through their website, at . Some background introduction to FLOSS applications is used for the benefit of those less familiar with such tools, and examples of some of the FLOSS content management systems (CMS) being used by OSNI are described. The experiences of the OSNI will facilitate a knowledgeable nursing contribution to the wider discussions on the applications of FLOSS within health and healthcare, and provides a model that many other groups could adopt.

What kind of information will be required if we are to reform health care?

The only logical way to avoid unnecessary future costs and improve quality is to analyze the past, providing input for the present. The informational management strategies are ready. There is continuous quality improvement, profiling with case-mix adjustment, and other techniques that will help us manage care and caring. But these strategies all rely on the customer being empowered to make truly informed decisions (the ethical principle of autonomy) and for us to advocate for patients (beneficence). Translating relevant data into information is the concentration of medical informatics. Virtually everyone in medical management can attest to the fact that, competitive forces notwithstanding, it is time for us to recognize not only that we are in the information business, but also that this information belongs to a larger community. Clearly, it is time to collaborate!

AIDMAN--advanced informatics distributed medical access network.

We describe AIDMAN, a pilot project in which health clinics in remote areas of Greece are connected with mainland hospitals, to provide routine clinical service for both chronic health care and accident and emergency. Clinical practice is supported through the use of the Virtual Consultation Workstation that is being developed and evaluated specifically for the project and which is based on readily available commercial products and international standards. The communication infrastructure remains a major obstacle to any telemedicine project, and for this reason, satellite communication is used in the AIDMAN project to overcome the current lack of digital links and bandwidth. The proposed system will provide real time video, high definition image, shared applications and data over a link running at 128 kbps. In this paper we discuss the design of the AIDMAN system, the Virtual Consultation Workstation and the communication channel.

[Information technology in medical education].

The role of information technology in educational models of under-graduate and post-graduate medical education is growing in 1980's influenced by PC's break-in in medical practice and creating relevant data basis, and, particularly, in 1990's by integration of information technology on international level, development of international network, Internet, Telemedicin, etc. The development of new educational information technology is evident, proving that information in transfer of medical knowledge, medical informatics and communication systems represent the base of medical practice, medical education and research in medical sciences. In relation to the traditional approaches in concept, contents and techniques of medical education, new models of education in training of health professionals, using new information technology, offer a number of benefits, such as: decentralization and access to relevant data sources, collecting and updating of data, multidisciplinary approach in solving problems and effective decision-making, and affirmation of team work within medical and non-medical disciplines. Without regard to the dynamics of change and progressive reform orientation within health sector, the development of modern medical education is inevitable for all systems a in which information technology and available data basis, as a base of effective and scientifically based medical education of health care providers, give guarantees for efficient health care and improvement of health of population.
