To evaluate the effectiveness and efficiency of a search strategy to find evidence-based answers to questions related to the possible occupational etiology of diseases.
A controlled trial of 70 occupational health physicians and 55 insurance physicians who were asked to answer one out of four 'occupational disease case-vignettes' following the steps of evidence-based medicine (EBM). The intervention group were given the search strategy as a tool.
The intervention group scored significantly better than the control group in answering the main question of the case-vignette correctly (57% versus 37%) using more adequate search terms. The intervention group scored significantly better regarding satisfaction with the applied search strategy (28% very satisfied versus 8%). We found no differences in time spent in solving the case or in the intention of future practice of EBM.
The introduction and application of specific search strategies can have a positive effect on the effectiveness of searching literature. Future initiatives for developing and testing specific search strategies in the field of occupational health should be encouraged.
评估一种检索策略的有效性和效率，以找到与疾病可能的职业病因相关问题的循证答案。
对70名职业健康医生和55名保险医生进行一项对照试验，要求他们按照循证医学（EBM）的步骤回答四个“职业病案例 vignettes”中的一个。干预组被给予该检索策略作为工具。
干预组在正确回答案例 vignette 的主要问题方面得分显著高于对照组（57%对37%），使用了更恰当的检索词。干预组对所应用检索策略的满意度得分显著更高（28%非常满意对8%）。我们发现在解决案例所花费的时间或未来循证医学实践的意图方面没有差异。
特定检索策略的引入和应用可对文献检索的有效性产生积极影响。应鼓励未来在职业健康领域开展开发和测试特定检索策略的倡议。
