1 Embase Find quick, relevant answers to your biomedical questions

2 Section 1. Review / Confirm understanding of your research needs

3 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 1. Your challenges & Research Needs

4 Section 2. Evidence Based Medicine / Systematic Searching

5 “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.systematic reviewsevidence-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.The Cochrane Library Section 2.

6 “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 2.

7 A real example of the high risks of NOT using Embase Section 2. Case Study: Embase & Evidence Based Medicine

8 Johns Hopkins’ Tragedy: Could Librarians Have Prevented a Death? Source: Section 2. Medicine Without Evidence

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

13 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?

14 Conference proceedings Very powerful Search including literature and information resources in a timely 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) 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 Section 3. How Embase Delivers Value…

15 Section 3.1 Content

16 Emtree: Biomedical thesaurus, over 60k terms AIP and In Process: Indexing added, from 2009 Conference Abstracts: Indexing added, from 2009 1947195019742009 And counting… 2,700 records added per day 1,000,000 records added per year Section 3.1 Content Overview Embase: Fully indexed: Over 7,700 journals (including MEDLINE), 1950- MEDLINE: 2,500 journals unique to Embase, mapped to Embase indexing, 1950- (including MEDLINE Classic) Embase Classic: Digitally scanned and re-indexed, 1947-1973

18 Similar overall pattern of coverage... but with two major differences 1. Pharmacology & toxicology Embase:11.2% (889 titles) MEDLINE: 8.3% (465 titles) 2. General clinical medicine Embase:10.5% (835 titles) MEDLINE: 8.9% (495 titles) Section 3.1 Embase vs MEDLINE – Scope

24 Section 3.2 Indexing (Emtree Thesaurus)

25 Section 3.2 Deep Indexing – EMTREE Emtree is a Life Science Thesaurus. A controlled vocabulary for Biomedicine and related Life Sciences Easy to Search Over 60,000 preferred terms and more than 270,000 synonyms Comprehensive Drug Searching Chemical names, trade names, laboratory/research codes, and more than 28,000 generic drugs and chemicals (FDA, EMEA and WHO) Up-To-Date The latest drugs, diseases, organisms and procedures are indexed and added annually Inclusive Terminology All MeSH terms, with links to more than 20,000 CAS registry number

26 60K terms (>260,000 synonyms) and all MeSH terms 29K drug and chemical terms Emtree updated 3 times a year (back-posting each time) All drug generic names described by FDA and EMA, all International Non-Proprietary Names (INNs) described by WHO from 2000. What is mapping? Mapping means that searchers get the same results regardless of which term they use, e.g. Vioxx (synonym) or rofecoxib (the preferred term). Section 3.2 Deep Indexing – EMTREE

28 2 thesaurus assisted searches but different results! Section 3.2 Embase vs PubMed

29 This article, although present in Medline, is not indexed with ‘digoxin’ and therefore our search for ‘digoxin’ and ‘antibacterial agents’ did not find this article – it’s found in Embase. Section 3.2 Embase vs PubMed
