Interactive software automates personalized radiation safety plans for Na131I therapy.

NRC regulations have liberalized the criteria for release from control of patients administered radioactive materials but require written radiation safety instruction if another individual is expected to receive more than 1 mSv. This necessitates calculation of expected doses, even when the calculated maximum likely dose is well below the 5 mSv release criterion. NRC interpretations of the regulation provide the biokinetic model to be used to evaluate the release criterion for patients administered Na131I, but do not provide guidance as to either the specifics of minimizing the dose of others or the length of time restrictions should remain in effect. Interactive software has been developed to facilitate creation of radiation safety plans tailored to patients' expected interactions. Day-by-day and cumulative effective exposures at several separation distances, including sleeping, are presented in grid format in a graphic interface. In an interview session, the patient proposes daily contacts, which are entered separately for each individual by point-and-click operation. Total dose estimates are accumulated and modified while negotiating contact schedules, guided by suggested age-specific limits. The software produces printed radiation safety recommendations specific to the clinical, dosing, and social situations and reflective of the patient's choice of combinations of close contact with others. It has been used in treating more than 100 patients and has been found to be very useful and well received.

The effect of a multimedia interactive tutorial on learning endodontic problem-solving.

New technology may create additional opportunities for learning in dental education. One of these new features is a multimedia approach, courseware combining sound, text, stills and video with interactive learning. A multimedia program was developed to train dental students and dental practitioners in decision making and problem solving in endodontics. This study compared the effects of the multimedia program with a more traditional approach consisting of written information, without interaction. 28, 4th-year dental students at the University of Kentucky in Lexington, KY, USA were randomly assigned to the multimedia or the text-based groups. They were given a written pre-test using 2 cases of dental pain and were instructed to study independently using either the multimedia program (group A) or the written information (group B). No restrictions were imposed on the amount of time to be invested, and the total study time was recorded for each student. 3 weeks after the pre-test, the students completed the post-test. A total of 18 students completed both the pre-test and the post-test and their scores were included in the final data. Statistical analysis of the average scores using paired t-tests revealed no significant difference between the performance of the students in either group, indicating that the multimedia approach to learning endodontic problem solving may successfully replace traditional learning strategies.

Cardiovascular interactions: an interactive tutorial and mathematical model.

The maintenance of an adequate cardiac output and systemic arterial blood pressure is a complex process with intricacies that are often difficult to understand. Cardiovascular Interactions is an active learning tool that demonstrates the interactions between the functions of the heart and peripheral circulation. This learning package consists of a Lab Book, a Model, and an Information file. The Lab Book is an interactive tutorial for exploring the relative influences of parameter changes on the cardiovascular system under normal, stressful, or pathophysiological conditions. The learners are guided to predict the direction and relative magnitude of changes of key variables in the cardiovascular system, evaluate the accuracy of their predictions, and describe the cause-and-effect mechanisms involved. Consequences of heart failure, hemorrhage, exercise, and changes in intrathoracic pressure can be explored. The results obtained in the Lab Book are based on a five-compartment mathematical Model, which reflects our current understanding of the basic control of the cardiovascular system. The Model was designed to be complex enough to be realistic, yet not so complex as to be overwhelming. An Information File contains definitions and descriptions of classical physiology about key concepts, including figures, and a detailed description of the Model. Hypertext tags embedded in the Lab Book are used to access the Information File. The Cardiovascular Interactions learning package was designed to run from its CD and so does not need to be installed.

IVR Test & Survey: a computer program to collect data via computerized telephonic applications.

Several studies have demonstrated the advantages of using interactive voice response (IVR) technology to collect self-report data from research participants and recipients of psychological/medical services. IVR allows participants to phone a computer and respond to recorded questions by pressing the appropriate touch-tone keys on their telephone. Because this technology offers substantial benefits in terms of cost and efficiency, it is surprising that it has not been more widely utilized by researchers and practitioners. Along with the automation of the administration and scoring of tests or surveys, IVR provides for questioning to be adapted to the participants' responses. One possible explanation for the failure to exploit this technology is the absence of easy-to-use software that does not require programming knowledge. This article describes IVR Test & Survey, a program to facilitate the administration, scoring, and analysis of information collected with the use of IVR technology.

Effectiveness of interactive videodisc instruction for the continuing education of paramedics.

OBJECTIVES: To evaluate the effectiveness of interactive videodisc (IVD) instruction of paramedics through the use of computer analysis of trip sheets. DESIGN/SETTING: Prospective, controlled, in an urban 9-1-1, paramedic, emergency medical services (EMS) system with total call volume of 62,000/year; 15,000 advanced life support (ALS). INTERVENTIONS: All 150 paramedics in the system received eight hours of IVD instruction covering five subject areas: 1) airway; 2) head/cervical trauma; 3) chest; 4) shock; and 5) cardiac arrest. Trip sheets from 9,943 runs in the pre-IVD period were subjected to computer analysis, and a compliance score was generated using previously developed algorithms that assigned a weight to each omission and commission. After a nine-month IVD training period, 4,303 cases were collected and analyzed in the post-IVD period. Statistical analyses were made using "Student's" t-test and Chi-square with alpha set at 0.05. EXCLUSIONS: Only those records of adult patients who fit one of the five protocols were eligible for computer analysis. Of the 9,943 cases in the pre-IVD group, 480 (4.8%) were excluded, all due to inadequate data recording by the paramedics. A statistically similar portion, 233 (5.4%) of the 4,303 post-IVD instruction cases were excluded (p = .15). RESULTS: Overall the mean compliance score of the pre-IVD group was 0.65 +/- 0.19 (+/- SD). The post-IVD group score was 0.65 +/- 0.19 (p = 0.99). Analysis of scores for each algorithm also showed no significant differences. This study had an observed power of .94 to detect a difference in compliance as small as 0.030. CONCLUSION: Eight hours of IVD instruction did not result in improved paramedic performance as judged by computer analysis of trip sheets.

Video vs. CD-ROM for teaching pelvic anatomy to third-year medical students. A comparison.

OBJECTIVE: To compare the effectiveness and student acceptance of video and CD-ROM review of pelvic anatomy in third-year obstetrics and gynecology students. STUDY DESIGN: A 34-item pretest was administered on the first day of the clerkship. Students were then randomized to watch a 45-minute video or use an interactive CD-ROM at home. All students took a posttest identical to the pretest. Examination scores were compared by paired and unpaired t test. Students completed a questionnaire on each method's ease, appropriateness, organization, appeal and time spent and whether they would recommend the method to others. RESULTS: One hundred seventy-six students were randomized, 88 to CD and 88 to video. There was 100% compliance, although not all questionnaire items were completed. The mean pretest score for both groups was 50%. The posttest CD mean score was significantly different from the posttest video mean (64% vs. 70%). Both groups significantly improved after the intervention. The video group noted ease of use, but only 49% recommended it for the future. The CD-ROM was recommended by 80%. Student comments favored the CD-ROM. CONCLUSION: Use of video review resulted in short-term significantly higher test scores, but students preferred an interactive CD-ROM. This method should be made available to all students during the rotation.

Technology-based vs. traditional instruction. A comparison of two methods for teaching the skill of performing a 12-lead ECG.

The purpose of this study was to compare the effectiveness of an interactive, multimedia CD-ROM with traditional methods of teaching the skill of performing a 12-lead ECG. A randomized pre/posttest experimental design was used. Seventy-seven baccalaureate nursing students in a required, senior-level critical-care course at a large midwestern university were recruited for the study. Two teaching methods were compared. The traditional method included a self-study module, a brief lecture and demonstration by an instructor, and hands-on experience using a plastic manikin and a real 12-lead ECG machine in the learning laboratory. The second method covered the same content using an interactive, multimedia CD-ROM embedded with virtual reality and supplemented with a self-study module. There were no significant (p < .05) baseline differences in pretest scores between the two groups and no significant differences by group in cognitive gains, student satisfaction with their learning method, or perception of self-efficacy in performing the skill. Overall results indicated that both groups were satisfied with their instructional method and were similar in their ability to demonstrate the skill correctly on a live, simulated patient. This evaluation study is a beginning step to assess new and potentially more cost-effective teaching methods and their effects on student learning outcomes and behaviors, including the transfer of skill acquisition via a computer simulation to a real patient.

"Informed consent" interactive videodisc for patients having a colonoscopy, a polypectomy, and an endoscopy.

These "informed consent" interactive videodisc programs use both graphic and live action sequences to describe in detail the diagnostic procedures of Endoscopy, Colonoscopy, and Polypectomy. Both benefits and possible risks are listed and described. After each sequence, the patient is asked whether the explanation is understood and/or whether the patient would like to discuss the procedure in more detail with a physician. The programs were designed for use with marginally literate patients and require no reading ability. Both programs are also ideal for general patient education.

Learning medical and dental sciences through interactive multi-media.

Health professionals in various fields of Medicine and Dentistry must acquire comprehensive technological knowledge in order to practice their professions. A large portion of that knowledge cannot be found in a textbook. Examples of this type of information are data gleaned from viewing microscopic slides and dissecting cadavers. In order to fully comprehend an area of study in medicine, the student relies on various resources (often physically unrelated, like the x-ray department and the dissection room). This situation makes the teaching and learning processes much more difficult to accomplish, since the instructor and students have to manipulate multiple media and take the courses in various sites. Today's technology allows us to design and create teaching and learning tools that can alleviate these difficulties. Personal computers are now used to capture and display a vast array of information through many different media: text, sound, images, photographs, illustrations, animation and video. This information can be presented to the user with audio-visual interfaces designed to facilitate efficient communication of ideas. It is controlled primarily by the use of the mouse, at one's own pace. This interactive, multi-media approach to teaching and learning is called "Edutainment" (Education and Entertainment). This demonstration will show how these new tools are used to teach and learn about various subjects related to Medicine, particularly in Dermatology and Dentistry. Several courseware applications were developed, addressing various aspects of the field: Cancers of the Skin, Dental Development, the Temporomandibular joint, the Masticatory Muscles etc. These programs provide anthropological data on growth collected through longitudinal research, diagnosis and treatments of pigmented lesions of the skin, thousands of digitized x-rays accessible through a relational database, the latest imaging technology used to diagnose the temporomandibular disorders, high-quality photographs of dissecting room material of the head and neck region, 3-dimensional animation of physiological principles of the temporomandibular joint movements, digital video of examination techniques, and other valuable resources to the user. The software were developed for both platforms, Macintosh and PC/Compatible, and all of them are in English and French, with some titles available in Spanish. To facilitate their distribution and usage, they were written to hybrid CD-ROMs, i.e., one CD-ROM was produced for each application, containing versions for both platforms in all languages. The CD-ROMs were recorded in our premises. During the presentation, the technical aspects of the development and production of a Multi-media document will be discussed along with the scientific content of the CD-ROM.
