Systematic Reviews
|April 23, 2025
Summary
Searching for gray literature is now feasible with search engines like Google. This study shares experiences and lessons learned from using Google searches to supplement systematic reviews, inviting further contributions.
Area of Science:
- Information Science
- Health Sciences
- Systematic Reviews
Background:
- Powerful search engines like Google enhance gray literature searching feasibility for systematic reviews.
- Existing research lacks hypothesis-testing studies on optimal Google search strategies for systematic reviews.
Purpose of the Study:
- To share practical experiences and lessons learned from using Google searches in five systematic review projects.
- To encourage the collection of experiential evidence for developing best practices in Google searching for systematic reviews.
Main Methods:
- Relaying user experiences with Google searches across five distinct systematic review projects.
- Documenting practical insights and challenges encountered during the search process.
Main Results:
- Google searches can effectively supplement traditional database searches for gray literature.
- Experiential evidence suggests Google is a valuable tool when integrated thoughtfully into systematic review workflows.
Conclusions:
- Developing "best practices" for Google searching in systematic reviews requires collective user experience.
- Further contributions from systematic review professionals are needed to build robust evidence on utilizing Google searches.

807
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

01:31Confirmation Biases
5.4K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
