Cochrane Library - Using the Advanced Search

Summary

This short tutorial demonstrates how to perform an advanced search in the Cochrane Library, focusing on evaluating the effectiveness of Tai Chi in preventing cardiovascular disease. The video guides users through using MeSH terms, keyword searches, and Boolean operators to create precise queries. It explains how to combine searches for multiple concepts, filter results by publication date or type, and review systematic reviews and clinical trials. The tutorial also covers exporting citations for reference management. By following this workflow, users can efficiently locate high-quality, relevant evidence for their research or clinical questions, making systematic literature searches more accessible and effective.

Takeaways

• 🩺 Cochrane Library is a national resource that can be accessed via Google for evidence-based research.
• 🔍 Advanced search in Cochrane allows users to search by title, abstract, keywords, publication type, and MeSH terms.
• 📂 The search manager tab helps combine different searches using Boolean operators like AND or OR.
• ❤️ To search for cardiovascular disease, MeSH terms can be exploded to include related terms such as heart disease and cardiovascular infections.
• 📝 Free keyword searches in titles and abstracts use the 'next' operator for phrases and wildcards instead of quotation marks.
• 🔄 Combining MeSH term searches with free keyword searches strengthens the overall search strategy for a concept.
• ☯️ For Tai Chi research, both MeSH terms and free keywords like 'taiji' or 'taishi' are used to cover all variations.
• 📊 Results include systematic reviews and trials, with Cochrane reviews available in full text while trials may be restricted.
• -
• 📅 Filtering options allow sorting by publication date, language, type, or topic to narrow down relevant studies.
• -
• 💾 Search results can be exported in formats like RIS for reference management or CSV for Excel, including abstracts for easier review.

Q & A

What is the primary purpose of this video?

The video provides a tutorial on how to conduct an advanced search in the Cochrane Library, specifically for evidence on the effectiveness of Tai Chi in preventing cardiovascular disease.

How can you access the Cochrane Library?

You can access the Cochrane Library by simply typing 'Cochrane' into Google, and it will be one of the top search results.

What is the difference between the three tabs in the advanced search section?

The three tabs in the advanced search section are: 1) The 'Search' tab, which allows searching in specific fields like title, abstract, and keywords. 2) The 'Mesh' tab, which is used for searching medical subject headings (MeSH). 3) The 'Search Manager' tab, which helps combine searches using Boolean operators.

What are MeSH terms and why are they important?

MeSH terms (Medical Subject Headings) are a standardized set of terms used to categorize and index medical topics. They help refine searches to be more precise and accurate when looking for specific medical information in databases like the Cochrane Library.

How can you refine a search using MeSH terms?

You can refine your search by selecting specific MeSH terms from the tree structure under broader topics. For example, under 'cardiovascular disease,' you can explore terms like 'heart disease' or 'cardiovascular infection.' You can then 'explode' the term to include all related concepts.

What Boolean operators are used in the Cochrane Library search, and what do they do?

The main Boolean operators used are 'OR' and 'AND.' The 'OR' operator allows you to include multiple related terms (e.g., 'cardiovascular disease' OR 'heart disease'). The 'AND' operator is used to combine different concepts (e.g., 'cardiovascular disease' AND 'Tai Chi').

How do you search for phrases in the Cochrane Library?

To search for a phrase consisting of two or more words together, you should use the 'next' operator instead of quotation marks. For example, 'cardiovascular next to disease' will search for variations like 'cardiovascular diseases' or 'cardiovascular infection.'

What should you do once you've combined your searches in the 'Search Manager' tab?

Once the searches are combined in the 'Search Manager' tab, you can view the results and refine them further by filtering by date, language, type, or topic. You can also export the citations.

Can you filter results by publication date in the Cochrane Library?

Yes, you can filter results by publication date. For example, you can choose to view studies published after a certain year or select a specific date range.

How can you export citations from the Cochrane Library?

To export citations, select the studies you want to export, click on 'Export Citation,' and then choose the desired format (e.g., RIS for reference management systems or CSV for Excel). You can also include the abstract before downloading the file.
