Objective
The purpose of this study was to evaluate websites providing information on treatment for depression to the public, and to evaluate changes in the quality of website information over time.Methods
Websites (N?=?25) addressing depression treatment were identified through the use of the Google search engine and by suggestions from healthcare professionals. Each website was evaluated based on the extent to which it addressed content areas deemed important by the public identified in previous research, overall quality as determined by the DISCERN, and reading level.Results
Overall, the quality of depression websites varied greatly. The majority of websites did not adequately answer the public’s questions about treatment options, and presented higher quality information in the area of pharmacological treatments as compared to other treatment options. An average reading level of 10.0 was found across websites. Upon re-evaluation, only 14 of 25 websites added new content, and the majority of websites did not improve in their overall website quality (as measured by the DISCERN).Conclusion and Practice Implications
Websites could be improved by addressing important questions that consumers have concerning depression, as well as by creating higher quality content in the areas of psychological, neurotherapeutic, and alternative treatments. 相似文献22.

The paper considers the limiting factors in EEG enhancement in the presence of electrosurgery interference and presents a
design for a useful fibre-optic EEG monitoring instrument which is free from such problems as electrical shock (micro and
macroshock), patient burns and susceptibility to electrosurgery interference associated with conventional EEG monitors. 相似文献

The direct measurement of blood pressure has found widespread use in intensive care units, operating rooms, and in emergency
departments. Infection, air embolism and thrombosis are some of the risks to patients associated with both the cannulation
procedure and with the apparatus used in the blood-pressure measuring process. Although there is constant revision in an attempt
to reduce these risks, they cannot be completely eliminated. The need for direct blood-pressure measurements and the physiological
effects of air embolism and thrombosis are reviewed. Infection and problems related to the techniques used to insert the catheters
are not discussed. 相似文献

The heart-lung machines for open-heart surgery have improved over the past 50 years; they rarely break down and are almost always equipped with backup batteries. The hand-cranking procedure only becomes necessary when a pump breaks down during perfusion or after the batteries have run out. In this study, the performance of hand cranking a roller pump was quantitatively assessed by an objective method using the ECCSIM-Lite educational simulator system. A roller pump connected to an extracorporeal circuit with an oxygenator and with gravity venous drainage was used. A flow sensor unit consisting of electromagnetic sensors was used to measure arterial and venous flow rates, and a built-in pressure sensor was used to measure the water level in the reservoir. A preliminary study of continuous cranking by a team of six people was conducted as a surprise drill. This system was then used at a perfusion seminar. At the seminar, 1-min hand-cranking drills were conducted by volunteers according to a prepared scenario. The data were calculated on site and trend graphs of individual performances were given to the participants as a handout. Preliminary studies showed that each person's performance was different. Results from 1-min drills showed that good performance was not related to the number of clinical cases experienced, years of practice, or experience in hand cranking. Hand cranking to maintain the target flow rate could be achieved without practice; however, manipulating the venous return clamp requires practice. While the necessity of performing hand cranking during perfusion due to pump failure is rare, we believe that it is beneficial for perfusionists and patients to include hand-cranking practice in periodic extracorporeal circulation crisis management drills because a drill allows perfusionists to mentally rehearse the procedures should such a crisis occur. 相似文献

Physics-Driven CFD Modeling of Complex Anatomical Cardiovascular Flows—A TCPC Case Study 总被引:5,自引:0,他引:5

Recent developments in medical image acquisition combined with the latest advancements in numerical methods for solving the Navier-Stokes equations have created unprecedented opportunities for developing simple and reliable computational fluid dynamics (CFD) tools for meeting patient-specific surgical planning objectives. However, for CFD to reach its full potential and gain the trust and confidence of medical practitioners, physics-driven numerical modeling is required. This study reports on the experience gained from an ongoing integrated CFD modeling effort aimed at developing an advanced numerical simulation tool capable of accurately predicting flow characteristics in an anatomically correct total cavopulmonary connection (TCPC). An anatomical intra-atrial TCPC model is reconstructed from a stack of magnetic resonance (MR) images acquired in vivo. An exact replica of the computational geometry was built using transparent rapid prototyping. Following the same approach as in earlier studies on idealized models, flow structures, pressure drops, and energy losses were assessed both numerically and experimentally, then compared. Numerical studies were performed with both a first-order accurate commercial software and a recently developed, second-order accurate, in-house flow solver. The commercial CFD model could, with reasonable accuracy, capture global flow quantities of interest such as control volume power losses and pressure drops and time-averaged flow patterns. However, for steady inflow conditions, both flow visualization experiments and particle image velocimetry (PIV) measurements revealed unsteady, complex, and highly 3D flow structures, which could not be captured by this numerical model with the available computational resources and additional modeling efforts that are described. Preliminary time-accurate computations with the in-house flow solver were shown to capture for the first time these complex flow features and yielded solutions in good agreement with the experimental observations. Flow fields obtained were similar for the studied total cardiac output range (1–3 l/min); however hydrodynamic power loss increased dramatically with increasing cardiac output, suggesting significant energy demand at exercise conditions. The simulation of cardiovascular flows poses a formidable challenge to even the most advanced CFD tools currently available. A successful prediction requires a two-pronged, physics-based approach, which integrates high-resolution CFD tools and high-resolution laboratory measurements. 相似文献

A computerized decision support system is presented. The system is used to aid in the situation of patient selection for the purpose of dental education and utilizes the PERT/CPM methodology and decision tables. It runs on a microcomputer and written in Basic. The input is a list of patient's needs, and the output is a tentative treatment plan, the chair time needed to complete the treatment, its cost, and the probability that the student will finish it on time. 相似文献

The clinical laboratory is regarded as a component of the medical care system extending from physician to laboratory staff and back to physician. From this concept a computer-based system of laboratory information is derived, emphasizing: (1) total laboratory responsibility for the test and its request, and (2) physician-oriented output reports. 相似文献
