To minimise retrieval bias, manual literature searches are a key part of the search process of any systematic review. Considering the need to have accurate information, valid results of the manual literature search are essential to ensure scientific standards; likewise efficient approaches that minimise the amount of personnel time required to conduct a manual literature search are of great interest.
The objective of this project was to determine the validity and efficiency of a new manual search method that utilises the scopus database.
We used the traditional manual search approach as the gold standard to determine the validity and efficiency of the proposed scopus method. Outcome measures included completeness of article detection and personnel time involved. Using both methods independently, we compared the results based on accuracy of the results, validity and time spent conducting the search, efficiency.
Regarding accuracy, the scopus method identified the same studies as the traditional approach indicating its validity. In terms of efficiency, using scopus led to a time saving of 62.5% compared with the traditional approach (3 h versus 8 h).
The scopus method can significantly improve the efficiency of manual searches and thus of systematic reviews.
为了将检索偏倚最小化，人工文献检索是任何系统评价检索过程的关键部分。考虑到需要准确的信息，有效的人工文献检索结果对于确保科学标准至关重要；同样，能够最大限度减少进行人工文献检索所需人员时间的高效方法也非常重要。
本项目的目的是确定利用 Scopus 数据库的新的人工搜索方法的有效性和效率。
我们使用传统的人工搜索方法作为金标准，以确定所提出的 Scopus 方法的有效性和效率。结果测量包括文章检测的完整性和涉及的人员时间。我们独立使用这两种方法，根据结果的准确性、有效性和搜索所花费的时间、效率进行比较。
在准确性方面，Scopus 方法与传统方法一样，识别出了相同的研究，表明其有效性。在效率方面，与传统方法相比，使用 Scopus 可以节省 62.5%的时间（3 小时与 8 小时）。
Scopus 方法可以显著提高人工搜索的效率，从而提高系统评价的效率。
