The MEDIGATE graphical user interface for entry of physical findings: design principles and implementation. Medical Examination Direct Iconic and Graphic Augmented Text Entry System.

The solution to many of the problems of the computer-based recording of the medical record has been elusive, largely due to difficulties in the capture of those data elements that comprise the records of the Present Illness and of the Physical Findings. Reliable input of data has proven to be more complex than originally envisioned by early work in the field. This has led to more research and development into better data collection protocols and easy to use human-computer interfaces as support tools. The Medical Examination Direct Iconic and Graphic Augmented Text Entry System (MEDIGATE System) is a computer enhanced interactive graphic and textual record of the findings from physical examinations designed to provide ease of user input and to support organization and processing of the data characterizing these findings. The primary design objective of the MEDIGATE System is to develop and evaluate different interface designs for recording observations from the physical examination in an attempt to overcome some of the deficiencies in this major component of the individual record of health and illness.

A simple WWW interface and quick response system-information query system for cross-sectional body dimensions.

We developed a query and analysis system for normal growth measurement of Japanese children on our WWW server using CGI. It has two subsystems. The first shows standard height and standard weight calculated by height. This subsystem can calculate the difference between measured height and the standard along with deviation and the ratio of measured weight to the standard weight. The second shows standard height, weight, head circumference, and chest circumference. This subsystem can calculate differences between the measurements and the standard as well as deviation. Because of the low amount of output required, very short turn-around time was required. This system also allows use of the same interface no matter which brand terminal is used and has wide reusability. This system will save doctors and nurses the difficulty of looking up a child's data, then having to make the calculation. We also compare the merits of CGI and Java.

Local CD-ROM in interaction with HTML documents over the Internet.

The internet and computer assisted learning have enhanced the possibilities of providing quality distance learning in dentistry. The use of multimedia material is an essential part of such distance learning courses. However the Internet technology available has limitations regarding transmission of large multimedia files. Therefore especially when addressing undergraduate students or geographically isolated professionals, large download times make distance learning unattractive. This problem was technically solved in a distance learning course for undergraduate students from all over Europe. The present communication describes a method to bypass the problem of transmitting large multimedia files by the use of a specially designed CD-ROM. This CD-ROM was run locally on the students' PC interacting with HTML documents sent over the Internet.

Students' evaluation of online course materials in fixed prosthodontics: a case study.

PURPOSE: The purpose of this study was to assess a new online course format for dental students. Preclinical Fixed Prosthodontics I is a didactic and laboratory course given in the first year of the dental school curriculum. In the spring semester of 1999, the didactic portion of the course was offered in a web-based format as a supplement to the traditional lecture format. METHODS: The study population was 53 first year dental students at one school. The study design was a one group post test without a control group. The online questionnaire consisted of multiple choice questions, Leikert scale questions and open-ended questions. Data were collected using Filemaker Pro and analyzed using Epilnfo. RESULTS: Student response rate was 96% (52/53). All of the students responded that they felt comfortable with their computer skills in utilizing this course format. Most (96%) responded that the online materials were either very helpful or helpful to them. About half, (54%) recommended that the online format be continued as a supplement to traditional lectures, while 28% recommended replacing traditional lectures with the new format in order to provide more laboratory time in the course. The syllabus, lecture materials, bulletin board and handouts were found to be the most helpful online features. The least helpful features were the listserve, decision tree, and e-mail options. Most frequently mentioned strengths of the online material were listed as 1) the ability to view material at their own pace and at a time convenient to them, 2) quality photographs in lecture materials and 3) online quizzes. Weaknesses of the course were ranked by students as 1) problems with access to the materials and the intranet system, 2) taking quizzes online and 3) difficulty in printing the web-based lecture materials. CONCLUSIONS: The delivery of web-based material as a course supplement in Fixed Prosthodontics I was determined to be an overall success. Fine tuning of problems with access to the materials took place throughout the course. The student feedback will help direct future development of web-based course materials in the dental school curriculum.

A systematic approach to modeling, capturing, and disseminating proteomics experimental data.

Both the generation and the analysis of proteome data are becoming increasingly widespread, and the field of proteomics is moving incrementally toward high-throughput approaches. Techniques are also increasing in complexity as the relevant technologies evolve. A standard representation of both the methods used and the data generated in proteomics experiments, analogous to that of the MIAME (minimum information about a microarray experiment) guidelines for transcriptomics, and the associated MAGE (microarray gene expression) object model and XML (extensible markup language) implementation, has yet to emerge. This hinders the handling, exchange, and dissemination of proteomics data. Here, we present a UML (unified modeling language) approach to proteomics experimental data, describe XML and SQL (structured query language) implementations of that model, and discuss capture, storage, and dissemination strategies. These make explicit what data might be most usefully captured about proteomics experiments and provide complementary routes toward the implementation of a proteome repository.

Modelling data across labs, genomes, space and time.

Logical models and physical specifications provide the foundation for storage, management and analysis of complex sets of data, and describe the relationships between measured data elements and metadata - the contextual descriptors that define the primary data. Here, we use imaging applications to illustrate the purpose of the various implementations of data specifications and the requirement for open, standardized, data formats to facilitate the sharing of critical digital data and metadata.

The attitudes of undergraduate students and staff to the use of electronic learning.

BACKGROUND: Computer-aided learning (CAL) offers advantages over traditional methods of learning as it allows students to work in their own time and pace. The School of Dentistry at the University of Birmingham has created an electronic learning website, named the Ecourse. This is designed to be a web-based supplement to the dental undergraduate curriculum. AIM: The aim of this study was to determine the attitudes of third year dental students and members of staff about the Ecourse website. METHOD: A questionnaire was produced and piloted before being distributed to all 65 third year dental students to obtain their opinions about the Ecourse website. The views of Ecourse were sought from four members of staff by performing qualitative, semi-structured interviews. RESULTS: Lecture handouts and textbooks were reported as the sources used most often, by 96% of students. Eighty-six per cent of students are accessing the Ecourse mainly at the School of Dentistry, but 53% are also accessing it at home. Students liked the multiple-choice questions, downloading extra notes and looking at pictures and animation to explain clinical procedures. The majority of the students (79%) want the Ecourse to be used as a supplement to the undergraduate programme and 7% wanted it to replace formal lectures. Staff recognised the benefits of the Ecourse but were concerned about plagiarism, the effect on lecture attendance and the lack of feedback from students on existing CAL material. CONCLUSION: Students consider the Ecourse as a positive method of supplementing traditional methods of learning in the dental undergraduate programme. However in contrast teaching staff expressed negative views on the use of e-learning.

The Internet: a practical example of the use of new technology in the assessment of vancomycin use in pediatrics. The Pediatric Prevention Network.

BACKGROUND: The rapid emergence of both new infections and new technologies has revolutionized health care during the past 50 years. Increased use of the Internet has enabled health care professionals to educate, interact, and collaborate throughout the world in ways never before possible. Increased use of vancomycin has been associated with the emergence of organisms with decreased susceptibility to vancomycin, such as Enterococcus and staphylococcal species. The purpose of this article is to describe our experience using Internet technology to assess vancomycin use at children's hospitals in the United States. METHODS: A Web-based evaluation was developed and distributed on the Internet to 57 Pediatric Prevention Network hospitals. The evaluation was structured to collect summary statistics on vancomycin use and admissions data by service for 1997 and 1998. RESULTS: Twenty-four hospitals were able to provide archived vancomycin use and patient admissions data; completed evaluations were returned from 15 hospitals (62.5% response rate). Personnel at 6 (40%) hospitals completed the evaluation directly on the Internet. CONCLUSIONS: In our study, Internet technology facilitated a more efficient evaluation of vancomycin use, but fewer than half of the personnel at Pediatric Prevention Network hospitals completed the evaluation directly on the Internet. It is unclear whether personnel at these hospitals were limited in Internet access, support, or understanding. Efforts should be directed to educate health care personnel on the advantages of the Internet. Furthermore, many of the pharmacy databases used in our assessment were not standardized across hospitals nor systematically validated. Understanding that limitations still remain-within the source of the data studied, the health care system sampled, and the Internet tools available-is essential because the Internet offers health care professionals today a tool both to protect patients and to improve quality throughout the world.

A comparison of technologies for database-driven websites for medical education.

Static web pages may be easy to setup using text processors or user-friendly web editing software. However, some basic knowledge of the implementation (HTML) is usually needed for final editing and maintenance. As a result many static web pages are left without appropriate updating. With a database driven, dynamic approach web contents may change through user interaction, the pages are usually easier to maintain, and design elements are separated from contents. Database driven solutions (or content management systems) for larger organizations may be purchased at many different levels of complexity. For smaller systems, such as separate courses or projects, they may, however, be developed locally. The present study compares four alternative technologies for database driven web pages. Each technology offers advantages and disadvantages and many issues need to be considered when selecting platform. The present study demonstrates that database driven web pages may be effectively deployed using free Open Source software. Details may be found at www.intermed.dk/datadriven.

Quality assessment of DSA, ultrasound and CT digital images compressed with the JPEG protocol.

Digital diagnostic images from subtraction angiography, computer tomography and ultrasound grabbed at 640 x 560 pixel and 320 x 280 pixel, eight-bit resolution were compressed at seven different levels with the 'lossy' JPEG algorithm in order to decrease the computer magnetic memory space required for their storage. After reconstruction, the deformations caused by the process were assessed (i) qualitatively: a perception test was performed twice, by five radiologists, on a total of 14 images compressed at various levels and (ii) quantitatively: the average grey level value per pixel was calculated at each compression level from each system's residual images obtained by subtracting the compressed image from the original and taking the absolute value of the result. It was concluded that images compressed at a ratio of about 10:1 were indistinguishable from the originals and hence could be considered acceptable for clinical use.

Internet2-based 3D PET image reconstruction using a PC cluster.

We describe an approach to fast iterative reconstruction from fully three-dimensional (3D) PET data using a network of PentiumIII PCs configured as a Beowulf cluster. To facilitate the use of this system, we have developed a browser-based interface using Java. The system compresses PET data on the user's machine, sends these data over a network, and instructs the PC cluster to reconstruct the image. The cluster implements a parallelized version of our preconditioned conjugate gradient method for fully 3D MAP image reconstruction. We report on the speed-up factors using the Beowulf approach and the impacts of communication latencies in the local cluster network and the network connection between the user's machine and our PC cluster.
