This paper describes an automated medical record designed to allow providers to enter patient data at the point of care. The system runs on PCs and Macintoshes and uses a graphical user interface and object-oriented programming to take advantage of current mouse and pen technologies. The provider acquires all relevant patient data by pointing and clicking at selections on input screens, many of which contain anatomical drawings to help the provider quickly and accurately describe patient findings. The system also generates a grammatically correct progress note using the problem-oriented structure. Furthermore, items identified in the assessment and plans portion of the program can be ported to expert systems for medical decisions assistance or to billing systems. The system allows the provider to obtain the necessary information on a focused patient visit in less than 5 min or to enter a complete history and physical. 相似文献

Ablation for the treatment of arrhythmias 总被引:2,自引:0,他引:2
McRury I.D. Haines D.E. 《Proceedings of the IEEE. Institute of Electrical and Electronics Engineers》1996,84(3):404-416
Surgical ablation of supraventricular cardiac arrhythmias has been rendered obsolete by the various modalities of electromagnetic transcatheter ablation techniques. Any ablation technique, including surgery is essentially the controlled destruction of a substrate which is acting as a source or a critical circuit limb of an arrhythmia. The most successful and popular modality is radio frequency (RF) ablation although other modalities such as dc shock, laser, microwave, and ultrasound are also being investigated. This review discusses the role of electrical ablation, especially RF ablation, as a treatment for supraventricular tachyarrhythmia and reviews the engineering principles and biological responses to ablation. A brief synopsis of the results of electrical catheter ablation procedures is presented. RF catheter ablation is a successful technique in clinical arrhythmia management, with reported success rates of greater than 95% in many series. The indications for clinical RF catheter ablation continue to broaden 相似文献

It is ten years since the Cartwright report was published, three years since the code of health and disability services consumers' rights was promulgated and two years since the code came into force which makes it due for review next year. This paper reviews the issues identified by Cartwright and the effect that her investigation into the "Unfortunate Experiment" has had on the provision of health services. Issues of clinical freedom, peer supervision and informed consent are discussed in relation to the Health and Disability Commissioner Act, the Privacy Act and concepts of partnership in health care. Some comments on the present state of the relationships between consumers and providers in the health system are included. 相似文献

Drawing on previous research in ethical behavior in information technology, this study examines the effects of group discussion, using virtual teams, on an individual’s intention to behave ethically/unethically. It was hypothesized that behavioral intention would be influenced by an individual’s attitude (toward ethical behavior), personal normative beliefs, ego strength, locus of control, perceived importance, gender and the scenario, and that computer-mediated group discussion would impact an individual’s ethical behavioral intention. This was tested through an experiment using five different ethical scenarios involving information technology. The results show that for two of the five scenarios, individual behavioral intention was significantly more unethical after computer-mediated group discussion than before, while for one scenario, individual behavioral intention was significantly more ethical after computer-mediated group discussion than before. The results of this study may help organizations to develop realistic training programs for IT professionals that account for changes in employee’s personal ethical models after interacting with others. 相似文献

The objective of this study was to evaluate the utility of a digital Brix refractometer for the assessment of success of passive transfer of maternal immunoglobulin compared with the measurement of serum total protein (STP) by refractometry. Blood samples (n = 400) were collected from calves at 3 to 6d of age. Serum IgG concentration was determined by radial immunodiffusion (RID), and STP and percentage Brix (%Brix) were determined using a digital refractometer. The mean IgG concentration was 24.1 g/L [standard deviation (SD) ± 10.0] with a range from 2.1 to 59.1 g/L. The mean STP concentration was 6.0 g/dL (SD ± 0.8) with a range from 4.4 to 8.8 g/dL. The mean %Brix concentration was 9.2% (SD ± 0.9) with a range of 7.3 to 12.4%. Brix percentage was highly correlated with IgG (r = 0.93). Test characteristics were calculated to assess failure of passive transfer (FPT; serum IgG <10 g/L). The sensitivity and specificity of STP at 5.5 g/dL were 76.3 and 94.4%, respectively. A receiver operating characteristic curve was created to plot the true positive rate against the false positive rate for consecutive %Brix values. The optimal combination of sensitivity (88.9%) and specificity (88.9%) was at 8.4% Brix. Serum total protein was also positively correlated with %Brix (r = 1.00) and IgG (r = 0.93). Dairy producers can successfully monitor their colostrum management and the overall success of passive transfer using a digital Brix refractometer to estimate IgG concentration of colostrum and calf serum. 相似文献

The influence of tooling material, i.e., graphite and WC-Co, on the microstructure of a spark plasma sintering (SPS) consolidated, nanostructured aluminum alloy is studied in this paper. The results show that tooling selection influences microstructure evolution, independent of process parameters. The influence of tooling on microstructure is rationalized on the basis of the following factors: heating rate, electrical current density, localized heating, and imposed pressure. A theoretic framework, based on the physical properties of graphite and WC-Co, is formulated to explain the observed behavior. 相似文献

Angle-dispersive X-ray diffraction and Raman scattering measurements were carried out to follow the crystal-to-crystal transformation occurring in PbZr 0.52 Ti 0.48 O 3 ceramic powders with either increasing hydrostatic pressure or decreasing temperature. A low-temperature monoclinic phase was confirmed to exist below 298 K. External pressures of several GPa were found to fundamentally alter the structural and polar properties of PZT near the MPB and novel phase transitions were found to occur at close to 5GPa at 298 K, 7.5 GPa at 154 K and 9 GPa at 44 K. Whereas X-ray diffraction data indicated no deviation from the cubic symmetry above these pressures at each given temperatures, the unusually strong and persistent Raman signals, similar to relaxor-specific spectral signatures, indicated the presence of symmetry-breaking disorder in this phase. Based on these results, an updated version of the Pressure-Temperature phase diagram is proposed. 相似文献
