The aim of this study was to evaluate learners’ acceptance of a webinar for continuing medical education that was instigated by the International Association of Oral and Maxillofacial Surgeons (IAOMS). A live, interactive webinar on orthognathic surgery was broadcast via the Internet. The learners’ acceptance of the webinar was evaluated using a standardized, validated questionnaire (Student Evaluation of Educational Quality, SEEQ). One hundred and fifty-three participants attended the webinar; 55 participants (46 male, nine female) completed the questionnaire. The mean age of the respondents was 41.6 ± 10.0 years. The age of male and female respondents did not differ significantly. The respondents were spread over five continents, with the highest number from Brazil. The SEEQ showed a high level of acceptance for almost all subscales. There was no statistically significant difference between male and female respondents concerning acceptance of the webinar (P = 0.614). The wide distribution of participants shows the potential for webinars as facilitators of barrier-free distribution of knowledge. The webinar was well accepted by the attendees independent of sex, specialty, and work experience. However, the sex ratio reflects the underrepresentation of women in oral and maxillofacial surgery. 相似文献

ObjectiveTo assess the diagnostic performance of electrophysiology and nerve ultrasound in ulnar neuropathies of varying clinical severity in 135 consecutive patients.MethodsClinical severity of ulnar neuropathy was graded on a 4 point scale from very mild (symptoms only) to severe (marked atrophy of intrinsic hand muscles). Sensitivity and localization ability of electrophysiology and nerve ultrasound were assessed for each point of the scale.ResultsUltrasound had higher sensitivity than electrophysiology in clinically very mild (20% and 3% for ultrasound and electrophysiology, respectively) and mild (62% and 47% for ultrasound and electrophysiology, respectively) neuropathies, had greater localizing ability in axonal ulnar neuropathies, and identified nerve hypermobility.Ultrasound nerve cross-sectional area had strong positive correlation with both clinical and electrophysiological severity scores, but with significant overlap across the severity groups.ConclusionThe diagnostic work-up of ulnar neuropathies was improved by using both electrophysiology and ultrasound at all levels of clinical severity. Ultrasound increased the diagnostic yield in very mild and mild neuropathies, localized all the ulnar neuropathies with abnormal non-localizing electrophysiology and identified nerve hypermobility.SignificanceThis is the first detailed analysis of the diagnostic performance of electrophysiology and ultrasound in ulnar neuropathies of varying severity. 相似文献

目的观察目标教学在手术室护理带教中的应用效果。方法选取2018年9月—2019年6月期间,医院手术室的48名实习护士,随机分为对照组和试验组,每组各24例。对照组行传统护理带教方法,试验组行目标教学带教。对比带教后两组考核成绩及带教满意度。结果带教后,试验组职业防护意识、风险意识、无菌观念、常见小中手术配合熟练度、常见小中手术护理要点掌握、基本工作职责及流程掌握等评分与对照组差异具有统计学意义(P<0.05)。试验组专科操作、操作测评及理论测评成绩与对照组差异具有统计学意义(P<0.05)。结论于手术室护理带教中应用目标教学,具有理想效果,有助于提升考核成绩及专业技能。 相似文献

Summary: Evidence-based medicine (EBM) has become a watchword for "the new" medical practice in the new century. Whether it represents a paradigm shift or simply a codification of the scientific method in medicine will be debated for years to come. Regardless of the place of EBM in medicine, this "movement" has served an important role in moving physician practice into the realm of becoming more scientific (albeit empirical) and transparent. There are still many problems to be addressed in the global application of the best evidence for medical practice. These include low-quality studies, delays in implementation of clear-cut improvements, outright fraud and deceit, and wariness on the part of physicians to change their practice. By working to understand the underpinnings of EBM (basic statistical concepts and critical thinking) we can advance the practice of medicine along the moral high road of science. 相似文献

The Australian higher education system is in a state of great change. The Federal education minister, Dr Brendan Nelson, has indicated that he intends to continue introducing far-reaching reforms that will impact significantly on how universities conduct teaching and research. The future allocation of government funding for university programs, including those in medical radiation, will have a significant effect on how those programs are delivered and could even determine whether programs remain viable. There will be a financial imperative for academic departments to strengthen research activity and to obtain funding from non-government sources, such as full-fee paying students, in order to generate enough income to cover program delivery. Medical radiation education in Australia is also facing many other challenges. Some of these are longstanding, such as the high cost of medical radiation program delivery, poor levels of research activity and difficulty in recruiting and retaining academic staff. Other problems have arisen recently, such as increased competition for students and a critical shortage of available training placements in clinical practice. The aim of this paper is to raise and explore these issues from a university perspective. 相似文献
