EmbaseFind quick, relevant answers to your biomedical questions

Section 1.Review / Confirm understanding of your research needs

• Conduct systematic reviews of the literature

• Set up complex search strategies and alerts for stakeholders and departments

• Search Medline and Embase together

• Set up and distribute alerts relating to evidence-based medicine

• Access the most up to date information related to a disease that you are tracking

• Make sure that all relevant information is disseminated throughout the organization

• Monitor and track all adverse events for early and complete detection of any and all adverse effects (signaling)

• Make sure you respond to your internal stakeholder’s request in a timely manner

Section 2.Evidence Based Medicine / Systematic Searching

“How do you know if one treatment will work better than

another, or if it will do more harm than good?”

Cochrane Reviews are systematic reviews of primary research in human health

care and health policy, and are internationally recognized as the highest standard

in evidence-based health care.

They investigate the effects of interventions for prevention, treatment and

rehabilitation. They also assess the accuracy of a diagnostic test for a given

condition in a specific patient group and setting.

They are published online in The Cochrane Library.

Section 2.

“How do you know if one treatment will work better than

another, or if it will do more harm than good?”

Each systematic review addresses a clearly formulated question.

For example:

Can antibiotics help in alleviating the symptoms of a sore throat? 

All the existing primary research on a topic that meets certain criteria is

searched for and collated, and then assessed using stringent guidelines, to

establish whether or not there is conclusive evidence about a specific treatment.

The reviews are updated regularly, ensuring that treatment decisions can be

based on the most up-to-date and reliable evidence.

Section 3.What is Embase and How it Supports Academic Institutions

Embase is the world’s most comprehensive, intelligent biomedical research tool, providing the drug and drug-related research community with reliable and authoritative content, to advance new biomedical and pharmaceutical discovery.

Confidence

Find all relevant articles that may not

otherwise be found by alternative databases

Deep Biomedical Indexing

All relevant, up-to-date, biomedical

information from the research literature

Precise Retrieval

Deep and focused research through

powerful retrieval tools

Section 3. What is Embase?

Conference proceedings

Very powerful Search Environment

...by including literature and information resources in a timely manner

...by reading full-text to identify drugs, diseases, adverse affects, clinical trials, drug trade names etc.

...by enabling advanced search filters to drill down a comprehensive search to a relevant and manageable record set

Scientific Journals

In Press (unpublished)

...by allowing users to automate searching and result management

Deep indexing using own taxonomy (EMTREE)

We make sure you don’t miss any

biomedical literature

They only close alternative is reading

all the articles

Good precision and recall balance

Automation and documentation
