The purchase price of a computer and its software is but a part of the cost of any automated system. There are many additional costs, including one-time costs of terminals, printers, multiplexors, microcomputers, consultants, workstations and retrospective conversion, and ongoing costs of maintenance and maintenance contracts for the equipment and software, telecommunications, and supplies. This paper examines those costs in an effort to produce a more realistic picture of an automated system.

For medical professionals to acquire computer literacy can be an arduous task. Resources for learning medical computing fall into four major categories: learning technical microcomputer use, computerizing an office practice, tracking patient care experience and integrating medical information systems. Both microcomputer use and tracking patient care experience are technical skills similar to learning any medical procedure with which physicians are already familiar. These skills can be acquired by consulting general, commercial resources such as computer stores, popular computer magazines or software manuals. Computerizing an office practice involves diagnosing office information problems by thoroughly analyzing how data flow during outpatient care. Medical information system design and management is a cognitive specialty in which principles of computer science and medical information management are applied to patient care experience.

MEDTUTOR is an interactive, microcomputer-based training package designed to teach medical and health professionals, as well as librarians and information specialists, how to use MEDLINE effectively. The objective of MEDTUTOR is to provide a comprehensive package for teaching the various commands and search techniques required for utilizing the MEDLINE database through the MEDLARS system. MEDTUTOR's menu-driven design allows novice users to learn about the content and use of MEDLINE, such as author searching, text word searching, MeSH indexing, etc., at their own pace and with considerable program feedback. In addition, MEDTUTOR provides the skilled searcher with a way to reinforce or recall previously-learned search techniques without incurring online charges. MEDTUTOR may be used in place of formal training, as a precursor to or as a refresher following formal training, or for review of a particular concept. It provides inexpensive and easily accessible instruction for searching MEDLINE.
Rapid acquisition and analysis of information in an Intensive Care Unit (ICU) setting is essential, even more so the documentation of the decision making process which has vital consequences for the lives of ICU patients. We describe an Ethernet based local area network (LAN) with clinical workstations (Macintosh fx, ci). Our Patient Archiving and Documentation System (PADS) represents a computerized patient record presently used in a university hospitals' ICU. Taking full advantage of the Macintosh based graphical user interface (GUI) our system enables nurses and doctors to perform the following tasks: admission, medical history taking, physical examination, generation of problem lists and follow up notes, access to laboratory data and reports, semiautomatic generation of a discharge summary including full word processor capabilities. Furthermore, the system offers rapid, consistent and complete automatic encoding of diagnoses following the International Classification of Disease (ICD; WHO, [1]). For educational purposes the user can also view disease entities or complications related to the diagnoses she/he encoded. The system has links to other educational programs such as cardiac auscultation. A MEDLINE literature search through a CD-ROM based system can be performed without exiting the system; also, CD-ROM based medical textbooks can be accessed as well. Commercially available Macintosh programs can be integrated in the system without existing the main program thus enabling users to customize their working environment. Additional options include automatic background monitoring of users learning behavior, analyses and graphical display of numerous epidemiological and health care related problems. Furthermore, we are in the process of integrating sound and digital video in our system. This system represents one in a line of modular departmental models which will eventually be integrated to form a decentralized Hospital Information System (HIS).
Computer-based training developed with high-level software packages offers a cost-efficient means of orienting large numbers of personnel to a hospital information system. Equally important, a decentralized, self-administered, self-paced tutorial allows professional personnel to get training where and when they want it, with as little or as much reinforcement as they desire. We will demonstrate the tutorial we developed to train 2500 clinical and unit support personnel to use the first clinical module of our Patient Care Information System. Although the Laboratory Results Inquiry function was simple to use, many of our staff had had little or no exposure to computers, and none knew how to use the system we would be implementing. About 300 of our 2500 personnel elected to come to mentored group classes, where the same computer-based tutorial was used, but a trained "superuser" was available to answer questions and offer guidance.
This paper is borne of the increasing interest and relevance of computers in nursing. It describes the method, and results obtained from a postal questionnaire survey distributed across the United Kingdom to gain information about the developments in computing in nursing education. The results indicate that considerable developments have been made, but that they are more piecemeal than co-ordinated. A selection of the results are presented and discussed, and one or two points concerning future proceedings are raised.
The impact of computers on healthcare delivery and management is both significant and increasing. Coupled with its potential educational benefits, computer-assisted instruction (CAI) has much to offer healthcare professionals. However, the individuals directly responsible for training nurses and other personnel typically have little knowledge about how computers can be used for training purposes. A series of workshops was designed for hospital educators and clinical nurse specialists to help them become computer literate and to provide them with the skills to evaluate, develop, and appropriately implement instructional software was emphasized during a series of formal seminars, guided individual instruction, and guided independent practice laboratory sessions. This approach resulted in a significant increase in participants' knowledge about computers while maintaining their positive attitudes toward the instructional uses of computers. A well-designed staff development program can provide these crucial individuals with the skills and knowledge required to use microcomputers and CAI as effective teaching and learning tools.
This paper describes a computer-aided tutorial for biological stereology. Stereology, a type of quantitative morphology, includes a collection of statistical methods that quantify the structural compartments that can be viewed in sections with light and electron microscopy. These methods provide volume, surface, length, shape, and number data, and help define the quantitative relationships among the structural compartments of biological hierarchies. Hierarchies, which connect structural data ranging in size from molecules to organs, serve as a central core to which the data of biological databases can be linked. The tutorial focuses on two objectives. It provides the user primarily interested in using quantitative morphology databases with background information, and offers a set of state-of-the-art tools to researchers wishing to use these methods in the laboratory. The main topics of the tutorial include: introduction to quantitative morphology, symbols/terms, data types, sampling, hierarchies, data interpretation, and utilities. The tutorial runs under the MS-DOS operating system and requires at least an IBM PC AT (or compatible), a color monitor (EGA, VGA), 540 KB of RAM, and 3 MB of hard disk space.
During the third-year medicine clerkship, students were instructed in online computer Physician Data Query (PDQ) searches. Each student completed computer searches in at least one of five tumor topics. Students assigned to selected tumor topics performed significantly better on test questions in their assigned topic as compared to the scores of students who were not assigned that topic. Although students were encouraged to use the PDQ ad libitum, within three months of completing the clerkship, only 22 students (20%) had conducted additional searches. We conclude that PDQ instruction may enhance students' knowledge about cancer. Student instruction can be effectively completed with minimal computer time. The results from our program evaluation and the limited student use following completion of the clerkship suggest that we should identify another user group, such as senior housestaff, to generate greater interest and more frequent use of the PDQ.

Objectives for the interactive experiences include exposure to a wide variety of computer applications; in-depth experience with at least one application; overcoming computer fear; appreciating the rigid, logical flow of computerized problem-solving; and appreciating the benefits and limitations of computer applications for a variety of purposes. Ultimately, a major purpose of transferring informatics content is related to stimulating students' imagination with respect to the computer's ability to aid their professional endeavors. Robinson (1984) describes the imagination factor: "I think the total potential of computers is only limited by our imagination. It's like giving an artist a palette that has an infinite number of colors, some of them invisible to the naked eye. . . It is a tool for the realization of ideas." Students who have been exposed to the benefits of major categories of computer applications can appreciate computer capabilities with respect to exploring scientific and nursing phenomena, and building databases to store and access information (Newbern, 1985). These students should have enough theoretical and experimental knowledge of computers to become actively involved in making creative, informed decisions about how computers will be applied to nursing in their professional setting. Hardin and Skiba (1982) noted a gap between the powerful information processing capabilities of the computer and its relatively limited use by nursing--a gap which still exists today. Students who have participated in an idea generation course on computer applications can help to bridge this gap, helping nursing to take full advantage of the computer-saturated environments of the future.
The purpose of this study was to determine if there was a relationship between learning style categories and attitudes toward computer assisted instruction (CAI). Few studies have attempted to compare adult learning style and attitude toward CAI. In a one group pre- and post-test design, two questionnaires were administered to adult students enrolled in a nursing research course, which integrated CAI as an instructional method. The Attitude Toward Computer Assisted Instruction Semantic Differential Tool (Allen, 1986) was completed twice. The Learning Style Inventory (Kolb, 1976), a self-report questionnaire to determine learning style, was completed once. Data analysis indicated a significantly greater negative attitude toward CAI post-test. Subjects in all four learning style categories had statistically significantly greater negative attitudes on the function subscale, with assimilators also having a significantly greater negative attitude on the creativity subscale, as well as in overall attitude. The increasingly negative attitude toward CAI in this study may reflect several factors: an evaluation of the CAI software, and subject expectations of the CAI that were not met.
