Many mobile phone resources have been developed to increase access to health education in the developing world, yet few studies have compared these resources or quantified their performance in a resource-limited setting. This study aims to compare the performance of resident physicians in answering clinical scenarios using PubMed abstracts accessed via the PubMed for Handhelds (PubMed4Hh) website versus medical/drug reference applications (Medical Apps) accessed via software on the mobile phone.
A two-arm comparative study with crossover design was conducted. Subjects, who were resident physicians at the University of Botswana, completed eight scenarios, each with multi-part questions. The primary outcome was a grade for each question. The primary independent variable was the intervention arm and other independent variables included residency and question.
Within each question type there were significant differences in 'percentage correct' between Medical Apps and PubMed4Hh for three of the six types of questions: drug-related, diagnosis/definitions, and treatment/management. Within each of these question types, Medical Apps had a higher percentage of fully correct responses than PubMed4Hh (63% vs 13%, 33% vs 12%, and 41% vs 13%, respectively). PubMed4Hh performed better for epidemiologic questions.
While mobile access to primary literature remains important and serves an information niche, mobile applications with condensed content may be more appropriate for point-of-care information needs. Further research is required to examine the specific information needs of clinicians in resource-limited settings and to evaluate the appropriateness of current resources in bridging location- and context-specific information gaps.
为了增加发展中国家获取健康教育的途径,许多移动电话资源已被开发出来,但很少有研究对这些资源进行比较,或在资源有限的情况下对其性能进行量化。本研究旨在比较通过 PubMed for Handhelds(PubMed4Hh)网站获取 PubMed 文摘和通过移动电话软件获取医学/药物参考应用程序(Medical Apps)来回答临床场景时,住院医师的表现。
采用具有交叉设计的双臂比较研究。博茨瓦纳大学的住院医师完成了 8 个场景,每个场景都有多个部分的问题。主要结果是每个问题的等级。主要的独立变量是干预组,其他独立变量包括住院医师和问题。
在每种问题类型中,Medical Apps 和 PubMed4Hh 在三种问题类型上的“正确百分比”存在显著差异:药物相关、诊断/定义和治疗/管理。在这些问题类型中的每一种中,Medical Apps 的完全正确回答比例都高于 PubMed4Hh(分别为 63%比 13%、33%比 12%和 41%比 13%)。PubMed4Hh 在流行病学问题上表现更好。
虽然通过移动设备访问主要文献仍然很重要,并且可以满足信息需求,但浓缩内容的移动应用程序可能更适合于即时信息需求。需要进一步研究来检验资源有限环境下临床医生的具体信息需求,并评估当前资源在弥合特定地点和背景信息差距方面的适宜性。
