A non-sequential Bayesian program for diagnosing acute abdominal pain was developed using an Amdahl mainframe accessed by a Texas Instrument remote terminal. Transferring the program to a MacIntosh SE/30 using hypercard was attended by increased utilisation from 15 to 44%.

This research evaluates the factors influencing the adoption of smart cards in the medical sector (a smart card has a micro-processor containing information about the patient: identification, emergency data (allergies, blood type, etc.), vaccination, drugs used, and the general medical record). This research was conducted after a pilot study designed to evaluate the use of such smart cards. Two hundred and ninety-nine professionals, along with 7248 clients, used the smart card for a year. The targeted population included mostly elderly people, infants, and pregnant women (the most intensive users of health care services). Following this pilot study, two surveys were conducted, together with numerous interviews, to assess the factors influencing adoption of the technology. A general picture emerged. indicating that although the new card is well-perceived by individuals, tangible benefits must be available to motivate professionals and clients to adopt the technology. Results show that the fundamental dimension that needs to be assessed before massive diffusion is the relative advantage to the professional. The system must provide a direct benefit to its user. The relative advantage of the system for the professional is directly linked to the obligation for the client to use the card. The system is beneficial for the professional only if the information on the card is complete. Technical adequacy is a necessary but not sufficient condition for adoption.
Various kinds of works of 6-11th-form schoolchildren on Macintosh computers were physiologically and hygienically assessed at the lesson of information science and computer engineering (ISCE), as well as typing. The fatigue of a visual analyzer was due to the time of looking through the data available on the display; the adverse changes of the higher nervous activity depends on the complexity of educational materials and the intensity of work on a computer. Three-hour studies in ISCE should be excluded from the time able of lessons as they do not meet hygienic requirements.
In order to analyze balance control, we developed a new inclinometry-based method to provide direct information about body sway in the side-to-side and forward-backward directions. We tested the clinical utility of this method for analyzing balance in Parkinson's disease (PD), and studied the clinical correlates of the balance measures in PD. Postural sway was measured during quiet stance with eyes open and eyes closed in 28 PD patients and in 32 age- and sex-matched control subjects. Postural sway was modeled using side-to-side and forward-backward directional sway movements, sway velocity, and sway area. The amount of postural sway in the PD patients was greater than in the control subjects, the higher level being most marked in patients with severe or long-duration PD. All the side-to-side directional sway parameters were abnormal in the PD patients compared with the control subjects (P
This paper describes an easy to use home-based eHealth system for chronic disease management. We present the design and implementation of a prototype for home based education, exercises, treatment and following-up, with the TV and a remote control as user interface. We also briefly describe field trials of the system for patients with COPD and diabetes, and their experience with the technology.
The anesthesiological systems Polinarkon-Vita for adults and children are described. These systems were developed at VNIIMP-VITA, Ltd. on the basis of basic model of the anesthesiological system Polinarkon-E-Vita. The following new important units of the fifth generation apparatuses for inhalation anesthesia (IA) are described: Anestezist-4 monocomponent evaporator for liquid anesthetics (enfluran and isofluran); Diana, Diana-Det, and Elan-NR apparatuses for mechanical lung ventilation (MLV); dosimeters of medical gases, etc. These systems implement monitoring of vitally important functions of patient and parameters of IN and MLV. The anesthesiological systems Polinarkon-Vita are recommended for medical practice and commercially available from VNIIMP-VITA, Ltd. as small lots.
Certain diseases and symptoms carry an overrepresentation of cancer. To be able to measure the strength of such an association it is necessary to be able to predict cancer development in the group being observed. A computer program for computers running under the MS DOS operating system has been developed for this purpose. The program is written in the CLIPPER programming language. The estimates are based on incidence and prevalence data from the Swedish Cancer Registry for the years 1958 to 1986. The program also computes confidence intervals based on the Poisson distribution. The results can be printed out or exported to other programs for further analysis.
