A prescription for better pharmacy computerization.

The net effect of these features in an integrated system is that the pharmacist spends time more productively managing patient drug therapy, not the computer system. The patient's location and demographics, once entered, are immediately available in a clinically useful form. Information about medications, the patient's responses to them and all other clinical parameters is available in the pharmacy without leaving the pharmacy application, making the pharmacist more effective and efficient. Physicians' orders are qualified by the system as they are entered, minimizing the number of nonproductive encounters between the pharmacist and the physician. Medication orders arrive at the pharmacy in a more timely manner and with fewer problems. The pharmacy can, in turn, be more responsive, helping the patient receive medication that is timely, accurate and clinically appropriate. These benefits arise primarily as a by-product of the pharmacy being integrated into an information system environment in which data is easily and directly accessed and shared. The more closely the pharmacy and its information requirements are examined, the more important the integration component appears. Many of the above benefits are not achievable with a dedicated stand-alone pharmacy computer system; some are achievable with an interface to a stand-alone nursing-station based HIS. In the pharmacy, is to increase and flourish in its role as an important and integral part of the healthcare delivery team, then access by the pharmacist to all patient information, and access by other providers to information contributed by the pharmacy is a necessary requisite. Improvement inpatient care can be the only result of such enhanced interchange.

Automated anesthesia surgery medical record system.

Manual recording of physiological data in patients receiving anesthesia or intensive care infrequently meets medical requirements or legal documentation standards. Automated recording allows the generation of reliable data that can be integrated into the patient's medical record. Such a system is beginning to function at University Hospital at Stony Brook, New York. Bedside medical devices (pulse oximeters, non-invasive blood pressure monitors, capnographs, infusion pumps and physiological monitors) from 18 operating rooms and 16 beds in the Anesthesia Intensive Care Unit are connected to a baseband Ethernet system. Data from the above devices are stored in a MicroVAX computer system. Data compression and interpretation, computation of derived values, statistical analysis of data from two related parameters are done by the bedside graphical microcomputer workstation. The MicroVAX computer and the workstation are also connected to the Ethernet system. The overall architecture of the automatic record system conforms to emerging standards for information exchange between bedside monitors and computer systems. Health care recipients and providers are likely to reap the benefits.

Computer applications in hospital pharmacy practice. I. Computer expectations/applications.

Following vendor selection of a pharmacy computer system, attention must be directed toward which computerized functions to include. Although most features are uniform among the various systems, a discussion is presented listing those applications considered the minimum acceptable for any hospital pharmacy computer system. The descriptions focus on computerization of those labor-intensive activities necessary to support drug distribution services. Computerized support of an intravenous (I.V.) admixture and unit dose program centers around label production and charging/crediting functions. Label production is used to generate a manual backup profile and unit dose cart fill list. The scope of information to include on I.V. and unit dose labels is described. Charging/crediting functions via computer are also discussed, with mention of free-form capabilities. Other computer applications mentioned include: medication profiling, drug interaction flagging, data confidentiality, census support, and hard copy reports. Feature selection depends on the aspects and unique needs that benefit most from computerization.

A computer filing system for drug use in a pregnancy consultation service.

A computerized database for documenting drug use in pregnancy was set up on a personal computer. Summaries of the information available from the literature on more than 700 drugs taken during pregnancy have already been entered and are currently in use. This reliable, cheap, handy, and personal system (the first available on the topic) may be a potentially useful instrument not only for drug consultation services, but for individual physicians, too.

Learning to control brain activity: a review of the production and control of EEG components for driving brain-computer interface (BCI) systems.

Brain-computer interface (BCI) technology relies on the ability of individuals to voluntarily and reliably produce changes in their electroencephalographic (EEG) activity. The present paper reviews research on cognitive tasks and other methods of generating and controlling specific changes in EEG activity that can be used to drive BCI systems. To date, motor imagery has been the most commonly used task. This paper explores the possibility that other cognitive tasks, including those used in imaging studies, may prove to be more effective. Other factors which influence performance are also considered in relation to selection of tasks, as well as training of subjects.

[Acquiring otoneurological results by computer. Evaluation after 2 years of experience].

Nearly all test performed in audiology and vestibulometry are based on quantitative paradigms and lead to results expressed in numerical form that are well suited for computer processing. Since 1980, the Oto-rhino-laryngology department of the Geneva University Hospital stores the complete patient record with all the results obtained in the otoneurological investigations (audiogram, impedance measurements, binaural tests, auditory-evoked potentials, electro-nystagmogram) on floppy disks using a PDP-11 micro-computer equipped with a low-speed printer and a Tektronix 4010 graphics terminal with an attached hard-copy unit. One of the main advantages of such a computer system is the gain in time for secretarial work such as patient record updating and archival. All test results are manually entered on a keyboard and the computer automatically produces reports with tables and graphs. The storage of patient files on floppy disks is fast, consumes little space and makes possible all types of statistical studies on the recorded clinical data. One should, however, be aware of the fact that the daily clinical use of even such a small computer system requires a solid technical infrastructure and lots of programming time. Nevertheless, the balance of our two years experience with this system is clearly positive and we foresee that the computer will become more and more an appreciated technical tool for several types of clinical work.

Three-dimensional reconstruction in dermatopathology--a personal computer-based system.

The purpose of the present study was to build a system for three-dimensional (3D) reconstruction of dermatopathological specimens using an easily available personal computer and graphic programs. A stereogram was generated by projecting thirty serial sections transferred into a Macintosh computer. The quality of the 3D images obtained by this method were high enough to show the net-like structure of rete ridges in normal epidermis, the antler-like branching of dermal papillae in seborrheic keratosis, and the bulge-like proliferation of tumor nests in basal cell carcinoma. This method was also helpful to assess oblique sectioning of the specimens, which sometimes produces a strange appearance in dermatopathological sections. The method presented here would not only help to better understand the 3D structures of dermatopathological specimens, but could also be used to examine 3D patterns of tumor invasion, which may contribute to the differential diagnosis of malignant tumors.

[Use of personal computers by diplomats of anesthesiology in Japan].

Use of personal computers by diplomats of the Japanese Board of Anesthesiology working in Japanese university hospitals was investigated. Unsigned questionnaires were returned from 232 diplomats of 18 anesthesia departments. The age of responders ranged from twenties to sixties. Personal computer systems are used by 223 diplomats (96.1%), while nine (3.9%) do not use them. The computer systems used are: Apple Macintosh 77%, IBM compatible PC 21% and UNIX 2%. Although 197 diplomats have e-mail addresses, only 162 of them actually send and receive e-mails. Diplomats in fifties use e-mail most actively and those in sixties come second.

A perspective on the usefulness of computers in nuclear medicine.

A computer system in clinical nuclear medicine has a wide variety of operations which it can perform. These range from simple data acquisition and tabulation to elaborate temporal and spatial reconstructions. Simultaneous recording of physiological data has also expanded the number of nuclear medical studies possible. The multiple-gated cardiac equilibrium analysis is the primary example of this format which has evolved rapidly with the availability of inexpensive central memory. Decreasing size and cost of processor units recently have led to the development of multiple processor systems. In some cases, the peripheral devices have a microprocessor already built in. The total cost of the computer system is essentially dictated by the number of peripheral devices.

An automatic microcomputer system for analysis of monophasic action potentials.

A computer system for rapid measurement and analysis of monophasic action potentials (MAPs) recorded in vivo was developed. MAPs recorded from the epicardium of mongrel dogs using a contact electrode were digitized by analog-to-digital conversion at a sampling rate of 1 kHz per channel for computer data acquisition. Activation time was detected using a sliding 10-point window at the location where the average positive dV/dT exceeds an adjustable threshold value in order to eliminate spurious detection due to baseline variability or motion artifact. Action potential duration (APD) was determined at 50% and 90% (APD50, APD90) repolarization levels at the first sample point below these detection levels. In addition, a tangent algorithm (APDtan) that detects peak negative dV/dT during repolarization was developed. APDtan was determined from the location of onset of activation to the intersection of tangent and baseline. APDtan allowed estimation of APD in the presence of subsequent premature beats when APD90 was not measurable. To validate activation time measurements, 4,600 action potentials were analyzed during fixed rate pacing. Over a range of paced coupling intervals from 200 to 1000 msec, an R2 value of 0.99968 and a slope of 0.9959 were obtained by linear regression between paced and calculated intervals. To validate APD measurements, 5035 action potentials were analyzed in five animals during fixed rate pacing (longer than 3 minutes) when action potential duration should be constant. Average coefficient of variation of 1.25%, 1.65%, and 1.14% were obtained for APD50, APD90, and APDtan, respectively. This algorithm provides a rapid and accurate method to analyze MAP activation and duration for basic physiological studies such as the determination of initiation of arrhythmias.

Measurements of the normal ventricular system with computer tomography of the brain. A preliminary study on 44 adults.

The brains of 44 normal adults were examined by computer tomography (CT) with the fine matrix EMI scanner. Measurements of various parts of the ventricular system showed a sexual difference and an increase with age. Absolute measurements are preferred to indices or ratios. Comparison with the same parameters in pneumoncephalography and ventricular casts showed good correlation. The need for larger investigations of the normal population is stressed.
