Which databases are suitable for which type of search?
And how do they work?
The main database for searching for biomedical article references is PubMed internationally, also because it is freely accessible. (The competitor database EMBASE, which is subject to a fee, is more extensive but very expensive and therefore not licensed at the University of Heidelberg.)
Supplementary databases to PubMed:
- The most important supplement for articles with the study type randomised and quasi-randomised controlled trials is the trials sub-database of the Cochrane Library (especially if, as in our case, EMBASE has not been licensed).
- For the creation of Systematic Reviews we recommend Web of Science Core Collection, the Cochrane Library and Google Scholar. For reading, the Cochrane Reviews of the Cochrane Library are methodologically of high quality.
Books and articles (simultaneously)
HEIDI offers the search for books in campus holdings/licenses of the University of Heidelberg as well as the search for German language articles and book chapters.
Google Scholar searches for all scientific document types that are available online worldwide.
In LIVIVO you can search extensively for international books and dissertations and, among other things, German language articles.
Citation analyses and Altmetrics
For citation analyses at journal level, see Journal rankings.
Altmetrics were introduced as an alternative to the pure analysis of citations and measure e.g. how often documents are accessed and downloaded, discussed and linked on web pages/blogs of scientific institutions or news portals, discussed and liked in social networks, stored in web-based reference management systems, or discussed in recommendation services such as F1000Prime - see also Wikipedia. Altmetric tools are available from different providers and are used by some publishers on their sites.
Clinical decision support, guidelines, evidence-based medicine (EbM)
Clinical Decision Support
Ideally, physicians should have a reference book at their disposal that evaluates current and high-quality literature on clinical topics, offers a good search function, and informs them by e-mail about thematic updates. The library has been licensing DynaMed for this purpose for several years for the entire UMM, including app use (the most well-known product of this kind is UpToDate, but it is also very expensive).
In the freely accessible ACCESSSS database, you can search for collaboratively assessed and annotated studies and systematic reviews from about 120 top journals and create e-mail alerts by subject areas.
The "Evidence-Based Medicine Guidelines" are a collection of about 1000 clinical guidelines that are regularly updated, supported by more than 4000 evidence summaries of articles from Level of evidence A to D. This database is only accessible free of charge via a search in ACCESSSS.
F1000Prime offers a "continually updated collection of over 145,000 recommendations of top articles in biology and medicine. Covering more than 3,700 peer-reviewed journals …" for $ 9,95 per month.
The Notfall-Standards database (in German) offers numerous clarification and treatment paths for emergency situations and is licensed for the Central Emergency Department.
NICE Pathways (for England) offer interactive diagrams with explanations based on NICE guidelines, see Guidelines.
On the page Guidelines there are explanations of German (AWMF) and international databases.
Evidence-based medicine (EbM)
Cochrane Germany offers some introductory information on evidence-based medicine at https://www.cochrane.de/de/ebm (in German).
The book Where is the proof? is also freely available as full text in HTML and PDF at http://de.testingtreatments.org (in German).
Differential diagnoses, drugs, NCBI, ICD
Differential diagnosis generator
Differential diagnosis generators are not licensed at the UMM, but some of them can be purchased by individuals, here is a small selection: VisualDx focuses on image material and can be licensed for $ 40,- per month or $ 400,- per year. The DDx tool Isabel for $ 150,- per year. FindZebra is free of charge and searches various free sources for rare diseases after entering symptoms.
here is a small list of recommended free drug databases:
- FORTA, drug evaluation for elderly patients
- Rote Liste (in German), registration with DocCheck
- Gelbe Liste, (in German), free registration
- PharmaWiki (in German), free of charge
- Drugs.com, free of charge
Study register, research data repositories
Author Identifier, author search, institution search
Author Identifier such as ORCID ID and ResearcherID are used to clearly assign publications to authors.
The Web of Science Core Collection allows searching for publications by authors without identifiers and by institutions.
Pictures and videos
The licensed Bilddatenbank Anatomie (Thieme) (in German) can be used after personal registration. The app Human Anatomy Atlas (by Visible Body) is installed on our borrowable tablets (iPads, only for MaReCum students).
On the Images under Creative Commons Licenses page, we introduce databases for searching images that are covered by Creative Commons copyright licenses.
On the page Videos & animations different licensed (JoVE, webop, Meditricks) and freely available offers are presented.
