- ItemAccess to top-cited emergency care articles (published between 2012 and 2016) without subscription(Department of Emergency Medicine, 2019) Hamzy, Murad Al; De Villiers, Dominique; Banner, Megan; Lamprecht, Hein; Bruijns, Stevan R.Introduction: Unrestricted access to journal publications speeds research progress, productivity, and knowledge translation, which in turn develops and promotes the efficient dissemination of content. We describe access to the 500 most-cited emergency medicine (EM) articles (published between 2012 and 2016) in terms of publisher-based access (open access or subscription), alternate access routes (self-archived or author provided), and relative cost of access.Methods: We used the Scopus database to identify the 500 most-cited EM articles published between 2012 and 2016. Access status was collected from the journal publisher. For studies not available via open access, we searched on Google, Google Scholar, Researchgate, Academia.edu, and the Unpaywall and Open Access Button browser plugins to locate self-archived copies. We contacted corresponding authors of the remaining inaccessible studies for a copy of each of their articles. We collected article processing and access costs from the journal publishers, and then calculated relative cost differences using the World Bank purchasing power parity index for the United States (U.S.), Germany, Turkey, China, Brazil, South Africa, and Australia. This allows costs to be understood relative to the economic context of the countries from which they originated.Results: We identified 500 articles for inclusion in the study. Of these, 167 (33%) were published in an open access format. Of the remaining 333 (67%), 204 (61%) were available elsewhere on the internet, 18 (4%) were provided by the authors, and 111 (22%) were accessible by subscription only. The mean article processing and access charges were $2,518.62 and $44.78, respectively. These costs were 2.24, 1.75, 2.28 and 1.56 times more expensive for South African, Chinese, Turkish, and Brazilian authors, respectively, than for U.S. authors (p<0.001 all).Conclusion: Despite the advantage of open access publication for knowledge translation, social responsibility, and increased citation, one in five of the 500 EM articles were accessible only via subscription. Access for scientists from upper-middle income countries was significantly hampered by cost. It is important to acknowledge the value this has for authors from low- and middle-income countries. Authors should also consider the citation advantage afforded by open access publishing when deciding where to publish.
- ItemEmergency point-of-care ultrasound applications : basic applications for the clinician performing bedside ultrasound(Health and Medical Publishing Group (HMPG), 2012-12) Lamprecht, Hein; Stander, Melanie; Van Hoving, NielClinicians who regularly manage critically ill and injured patients often lack the immediate clinical information that is essential to make correct clinical decisions. Emergency point-of-care ultrasound (EPCUS), performed by bedside clinicians, may provide some of this information, which will help in making the correct clinical decisions and improve overall patient outcomes.
- ItemEmergency point-of-care ultrasound training, credentialing and accreditation(Health and Medical Publishing Group (HMPG), 2012-12) Lamprecht, HeinEmergency point-of-care ultrasound (EPCUS), performed by doctors, has recently become a popular skill that is used to enhance the accuracy of physical examination of patients. EPCUS provides additional, real-time, patient data which would not have been otherwise available. The effect is improved diagnostic accuracy and reduction in procedural error rates. Ultrasound technology is rapidly evolving. Machines are now more compact, portable, durable, and simpler to use, and provide improved image quality.
- ItemPoor return on investment : investigating the barriers that cause low credentialing yields in a resource-limited clinical ultrasound training programme(SpringerOpen, 2018-02-21) Lamprecht, Hein; Lemke, Gustav; Van Hoving, Daniel; Kruger, Thinus; Wallis, LeeBackground: Clinical ultrasound is commonly used in medical practices worldwide due to the multiple benefits the modality offers clinicians. Rigorous credentialing standards are necessary to safeguard patients against operator errors. The purpose of the study was to establish and analyse the barriers that specifically lead to poor credentialing success within a resource-limited clinical ultrasound training programme. Methods: An electronic cross-sectional survey was e-mailed to all trainees who attended the introductory clinical ultrasound courses held in Cape Town since its inception in 2009 to 2013. All trainees were followed until they completed their training programme in 2015. Results: Only one fifth of trainees (n = 43, 19.7%), who entered the Cape Town training programme, credentialed successfully. Ninety (n = 90, 41.3%) trainees responded to the survey. Eighty-six (n = 86) surveys were included for analysis. Time constraints were the highest ranked barrier amongst all trainees. Access barriers (to trainers and ultrasound machines) were the second highest ranked amongst the non-credentialed group. A combination between access and logistical barriers (e.g. difficulty in finding patients with pathology to scan) were the second highest ranked in the credentialed group. Conclusions: Access barriers conspire to burden the Cape Town clinical ultrasound training programme. Novel solutions are necessary to overcome these access barriers to improve future credentialing success.
