Purpose: To determine if nurses are able to identify medication errors that have the potential to bypass computer physician order entry (CPOE) and smart ordering systems. Background: Medical care systems employ computer “smart” systems to reduce medication errors by using artificial intelligence (preprogrammed methods of decision support and error reduction). However, these systems are not perfect and they can be bypassed. Nurses who carry out the order represent the last check point in error prevention prior to the administration of medication orders. Methods: A paper exercise was created with 513 physician orders. Nurses were asked to indicate whether they would carry out the order, refuse to carry out the order, consult a pharmacist for clarification, or carry out the order with special precautions. Nurses were given the option of using any nursing or medical reference. Results: The rate of correctly identifying 23 of the contraindicated orders was low. Both experienced and inexperienced nurses had high rates of not identifying the errors despite similar use of references and requests for assistance from pharmacists. Conclusions: This study demonstrates that if an error escapes a smart system, nurses were able to identify most of these errors, but not all of these. The current system features high stress, self-esteem issues, time pressure, high volume, and high risk. The system must change radically to meet the public’s expectations of being nearly error free which can only be achieved with smarter systems that are more resistant to human errors.

射频和微波系统中元件和子系统的小型化显著减少了同轴连接器的数量,而用直接印制电路板(PCB)安装来代替同轴连接器.因此,在确定器件的特性时,应与矢量网络分析仪的常用接口相连.测试夹具代替了这类接口并提供了优良的解决方案,但测试夹具结构必须精确设计,且特性为已知.此外,夹具对电路的影响必须从测量结果中除去.夹具还须加以校准,通常是借助短路-开路-负载-直通(SOLT)校准技术进行校准.为了获得精确、重复的测量结果,全面了解进行夹具内测量的过程是重要的.对用来评估移动电话的带通滤波器的夹具进行校准,可以为必须考虑的细节和处理过程提供一个范例.

电流反馈的结构与电压反馈大不相同.电流反馈非常适合用于高速信号,因为它没有基础增益带宽积的限制,同时也由于其固有的线性度.电流反馈运算放大器的带宽略微受到增益的约束,但不像电压反馈器件那么严重.再者,压摆率并非受到内部偏置电流的限制,而是受到晶体管自身速度的限制.这样在给定偏置电流的条件下可以使用更快的压摆率,而不必采用正反馈或其它压摆率提升技术.

Open Journal of Emergency Medicine 2016年第2期4卷 33-37页

The management of sepsis evolved recently with the publication of three large trials (referred to as the sepsis trilogy) investigating the efficacy of early goal-directed therapy (EGDT). Our goal was to determine if the publication of these trials has influenced the use of EGDT when caring for patients with severe sepsis and septic shock in the emergency department (ED). In February 2014, we surveyed a sample of board-certified emergency medicine physicians regarding their use of EGDT in the ED. A follow-up survey was sent after the publication of the sepsis trilogy. Data was analyzed using 95% confidence intervals to determine if there was a change in the use of EGDT following the publication of the above trials. Subgroup analyses were also performed with regard to academic affiliation and emergency department volume. Surveys were sent to 308 and 350 physicians in the pre-and post-publication periods, respectively. Overall, ED use of EGDT did not change with publication of the sepsis trilogy, 48.7% (CI 39.3% - 58.2%) before and 50.5% (CI 40.6% - 60.3%) after. Subgroup analysis revealed that academic-affiliated EDs significantly decreased EGDT use following the sepsis trilogy while nonacademic departments significantly increased EGDT use. Use of EGDT was significantly greater in community departments versus academic departments following the publication of the sepsis trilogy. There was no change overall in the use of EGDT protocols when caring for patients with severe sepsis and septic shock, but subgroup analyses revealed that academic departments decreased their use of EGDT while community departments increased use of EGDT. This may be due to varying rates of uptake of the medical literature between academic and community healthcare systems.
