|摘要: ||系統性文獻回顧（Systematic Reviews, SR）乃以實證醫學為基礎所發展延伸的研究文獻，為摒除學術傳播偏差提升該類型文獻之完整性與客觀性，醫學圖書館員會參與其中協助資料檢索與相關資訊服務。根據2017年美國醫學圖書館學會（Medical Library Association, MLA）發佈之「醫學圖書館員終身學習與成就專業能力」（MLA Competencies for Lifelong Learning and Professional Success），首次明訂SR文獻檢索及其相關知識為館員必備之專業能力。然因國內參與該研究之館員仍在少數，故本研究乃以「醫學圖書館員參與Medline所收錄的SR」為研究對象，並應用書目分析與內容分析法萃取出重要資訊，藉以瞭解其文獻特質、圖書館員角色、資料庫與檢索策略應用、學科分布及通訊作者特質，提供欲參與該研究之館員參考。|
Systematic Reviews (SR) is extended literature review based on evidence-based medicine. In order to reduce the bias on academic communication and enhance the integrity and objectiveness of such type of literature review, medical librarians will participate in service to assist the researcher in data searching and information related work. According to the "MLA Competencies for Lifelong Learning and Professional Success" published by the Medical Library Association (MLA) in 2017, for the first time, the ability of literature retrieval of systematic review, and its related knowledge, are the necessary professional qualifications for librarians. However, the number of librarians participating in the study is still a minority. Therefore, this study aims to understand the characteristics of literature review, role of librarians, pool of database and application of searching strategy, distribution of department and characteristics of corresponding author by using database on SR study from Medline database involved by medical librarians, and also applying bibliographic analysis and content analysis to extract important information. Such research might provide reference for librarians who wish to participate in the study.
The results of the study reveal that: (1) in the characteristics of literature review, a total of 786 in line with the conditions of the literature review of SR from 2014 to 2016 years. More medical librarians involved in the increasing amount of literature review of SR. In order to enhance the study quality of SR, we should follow the guidelines for research. Among them, PRISMA is the most commonly used and simple guidelines; the publication of SR should also provide a complete searching strategy and process of data searching for assurance of good searching quality. (2) In the role of librarians, the proportion of librarians as co-author occupies 61.58%; the rest of them mentioned the contribution of librarian in the text or acknowledgement. (3) In the database application and searching strategy part, 192 kinds of databases appeared. An average of 5.16 or more databases searched to collect complete SR research data. The type of database contains “Indexing & Abstracting Database”, the “Citation Index Database”, the “Fulltext Database”, and the “Clinical Register Database”. The highest data searched was on Medline and PubMed. In addition, usually we used Medline database to establish the searching terms and searching strategies, then perform fine-tuning by cross-database searching. (4) The corresponding author of all SR belongs to 34 countries, with the largest number of them is from the United States, followed by Canada and the United Kingdom. Taiwan has only two SR, and the librarian''s contribution only appears acknowledgement. (5) 96.07% of the SR was included in the JCR, of which up to 50.66% of the journals listed as the first quintiles in the subjected area.
According to the results and findings in the study, recommendations are provide as below: (1) Librarians should be proficient in the medical vocabulary, evidence based medicine, and systematic review related knowledge, and should be familiar with the scope of the databases, the indexing methods and search syntax; (2) For conducting the research of systematic review, clinical staffs can seek for the assistance of medical librarians, or participate in the team for a joint study to improve the quality of research.
