摘要

The aim of this study was to assess the contents of medical textbooks, eMedicine (Medscape) topics, and YouTube videos on cardiovascular mechanisms. Medical textbooks, eMedicine articles, and YouTube were searched for cardiovascular mechanisms. Using appraisal forms, copies of these resources and videos were evaluated independently by three assessors. Most textbooks were brief in explaining mechanisms. Although the overall average percentage committed to cardiovascular mechanisms in physiology textbooks (n = 7) was 16.1% and pathology textbooks (n = 4) was 17.5%, there was less emphasis on mechanisms in most internal medicine textbooks (n = 6), with a total average of 6.9%. In addition, flow diagrams explaining mechanisms were lacking. However, eMedicine topics (n = 48) discussed mechanisms adequately in 22.9% (11 of 48) topics, and the percentage of content allocated to cardiovascular mechanisms was higher (15.8%, 46.2 of 292) compared with that of any internal medicine textbooks. Only 29 YouTube videos fulfilled the inclusion criteria. Of these, 16 YouTube were educationally useful, scoring 14.1 ± 0.5 (mean ± SD). The remaining 13 videos were not educationally useful, scoring 6.1 ± 1.7. The concordance between the assessors on applying the criteria measured by κ score was in the range of 0.55–0.96. In conclusion, despite the importance of mechanisms, most textbooks and YouTube videos were deficient in cardiovascular mechanisms. eMedicine topics discussed cardiovascular mechanisms for some diseases, but there were no flow diagrams or multimedia explaining mechanisms. These deficiencies in learning resources could add to the challenges faced by students in understanding cardiovascular mechanisms.
機(jī)譯:這項(xiàng)研究的目的是評(píng)估醫(yī)學(xué)教科書,eMedicine(Medscape)主題以及有關(guān)心血管機(jī)制的YouTube視頻的內(nèi)容。在醫(yī)學(xué)教科書,eMedicine文章和YouTube上搜索了心血管機(jī)制。使用評(píng)估表,由三名評(píng)估者獨(dú)立評(píng)估了這些資源和視頻的副本。大多數(shù)教科書都簡(jiǎn)要介紹了機(jī)制。盡管生理教科書(n = 7)中致力于心血管機(jī)制的總體平均百分比為16.1%,病理學(xué)教科書(n = 4)為17.5%,但是大多數(shù)內(nèi)科教科書(n = 6)中對(duì)心血管機(jī)制的重視程度較低,總計(jì)平均6.9%。此外,缺少解釋機(jī)制的流程圖。但是,eMedicine主題(n = 48)在22.9%(48個(gè)中的11個(gè))主題中充分討論了機(jī)制,與任何內(nèi)科教科書相比,分配給心血管機(jī)制的內(nèi)容百分比更高(15.8%,292個(gè)中的46.2)。僅29個(gè)YouTube視頻符合納入標(biāo)準(zhǔn)。其中,有16個(gè)YouTube在教育方面很有用,得分為14.1±0.5(平均值±標(biāo)準(zhǔn)差)。其余13個(gè)視頻在教育上沒有用,得分為6.1±1.7。評(píng)估者在應(yīng)用以κ評(píng)分衡量的標(biāo)準(zhǔn)之間的一致性在0.55-0.96之間??傊?,盡管機(jī)制很重要,但大多數(shù)教科書和YouTube視頻在心血管機(jī)制方面均不足。電子醫(yī)學(xué)主題討論了某些疾病的心血管機(jī)制,但沒有流程圖或多媒體解釋機(jī)制。學(xué)習(xí)資源的這些不足可能會(huì)增加學(xué)生在理解心血管機(jī)制方面所面臨的挑戰(zhàn)。
