- 12. DEEP INDEXING 12
- 13. Deep indexing - Emtree 60K terms (>260,000 synonyms) and all MeSH terms Over 30K drug and chemical terms Updated 3 times a year (back-posting each time) All drug generic What is names described by mapping? FDA and EMA, all Mapping means International Non- that searchers get Proprietary Names the same results (INNs) described by regardless of WHO from 2000. which term they use, e.g. Vioxx (synonym) or rofecoxib (the preferred term).
- 14. Deep indexing - Emtree 14 study types, including NEW Diagnostic Test Accuracy Study 78 drug and disease subheadings
- 16. Start searching… Find the best terms for your search and include synonyms automatically with autocomplete in Quick Search
- 17. Click on Disease Filter for example, to see which diseases are referenced with Januvia, either as a therapeutic area or side effect.
- 18. Find deep drug and disease relationships without having to consult the full text.

- 20. Poll The poll should appear on your screen shortly...
- 21. Let’s take a look at Embase... • Building and combining searches • Refining your search • Setting up email alerts and saving your searches
- 22. Building and combining searches • Use single quotes to capture a phrase „diabetes mellitus‟ for example (not with Autocomplete in Quick Search) • Break up your search into individual searches, such as a drug search (in Drug Search form) and a disease search (in Disease Search form) and combine your results in Session Results • Run your cursor over your search to Edit or copy to a Search Form for guided editing. • Truncation and operators, AND, OR, NOT, NEXT, NEAR Refer to http://info.embase.com/helpfiles for more guidance and links to materials such as the Quick User Guide.
- 23. Refining your search • Quick and Advanced Limits on Advanced, Drug and Disease Search forms • Major Focus on all advanced forms – major drugs and diseases retrieved • Field limits under Advanced Search box to search in specific fields such as article title, abstract, conference name, drug name etc • Drug and Disease Subheadings to limit to specific concepts such as Adverse Drug Reaction, Drug Comparison and Side Effect. • Filters on Session Results page for specific diseases or study types for example Check out our training videos at www.trainingdesk.elsevier.com/embase for more guidance.

Notes de l'éditeur
- Content is key/backbone for Embase and Emtree provides consistency for Embase indexing and retrieval.(Over 450k conference abstracts)Embase continue to focus on building up content but also on enhancing functionality and indexing/quality.
- So where does that leave us?Taking a holistic view, Embase today covers almost 8,000 active biomedical journals.Almost 5,400 of these titles are indexed at Embase, meaning that they are indexed directly by Embase indexers. These are shown in the dark blue line at the top.Articles from a further 2,500 journals, shown here in the yellow box, are indexed by MEDLINE, sent to the Embase production site and loaded on Embase after conversion to Embase format. Details of the conversion are given in a white paper from 2011.And the centre box, in green, shows that over 3,000 journals are shared by Embase and MEDLINE – which is not surprising given that both Embase and MEDLINE cover the same broad topic of biomedicine.This leaves nearly 2,400 journals in the blue box on the left that are unique to Embase. The following slides show where they come from.
- Fast forward 65 years, and what does Embase look like now?First and foremost, Embase is renowned for its coverage of drugs and pharmacology. Over 12% of Embase journals today focus on pharmacology, pharmaceutics and toxicology. Of course, there is also extensive coverage of drugs information from many other journals, and today well over 50% of all records in Embase, year-in-year-out, contain searchable information on drugs.Two other areas that come close to drugs and pharmacology in their coverage in Embase are shown here in different shades of purple.... and this is complemented by all the topics of clinical medicine which taken together fill almost three quarters of Embase’s current coverage.The remaining 28% of Embase coverage is devoted to less purely clinical topics such as public health, basic biomedical science and other topics covered by journals licensed from MEDLINE. I’ll return to this in a few minutes.
- If we compare this pattern of content coverage with that of MEDLINE, the overall picture looks quite similar ... however, there are two major differences.The first is not surprising, given Embase’s focus on drugs & pharmacology. Embase has significantly greater coverage in this area, both in percentage terms and when measured by the total number of journals covered. The inset shows just a few of the journal titles that are unique to Embase. But perhaps more surprisingly, Embase has greater coverage than MEDLINE of general clinical medicine. As illustrated here, this difference is mainly due to Embase’s coverage of general medical journals from countries around the world.
- Topic area is based on the Elsevier ASJC (All science journal classification) code that all journals have, conferences are not included. MEDLINE has similar topics and the list above is oosely based upon this classification toenable comparison.The classification is somewhat arbitrary in that the number of journals in any one classification depends upon how it is defined. PLEASE bear in mind this is a journal classification and does not indicate the number of relevant articles on a particular topic in Embase! This list is mostly for internal use only, to help us understand and manage the journal content, even though we share it with interested users. We have looked at all unique MEDLINE titles in these drug related areas last year and most are report-like etc so not really appropriate for inclusion for indexing by our own indexers. In some cases MEDLINE has a different way of classifying, but it is always useful to review such lists and decisions.
- Unique features:Every conference is summarized by a searchable review recordAll conference abstract records include searchable online abstractsAll conference abstracts & reviews are indexed with EmtreeConference name, date and location are searchable450K conferences covered.

Registering also means you receive all up to date information such as upcoming webinars.Antibiotic and digoxin with drug combinationANDCongestive heart failure with drug therapyAND PneumoniaSave this search – remove drug therapy from disease and rerun main searchNow in session results, remove drug comparison from drug sub-searches and note asterix (indicates which searches have been effected by a change to a related search)– now click on result number to update your search strategy.Re-use a named search in a new search. For example you may have a group of #limitstrial AND digoxin
- Compare the effectiveness of sitagliptin and saxagliptin in the treatment of type II diabetes mellitus (show this in Emtree)Go to Drug Search and type in sitagliptin and saxagliptin with drug comparison. Go to Emtree and show diabetes mellitus and then go to ‘type 2 diabetes mellitus’. Take this to Disease Search and combine with disease subheading ‘drug therapy’. Combine both searches.Show editing options. NOT [review]/limAdvanced combine on the Session Results: Last search above NOT saxagliptin search, for example #2 NOT #1.Quickly show Emtree to find suitable terms/subject headings and then using Drug Search to add subheadings.
- Find disease management studies for Type II diabetesGo to Emtree and type in diabetes. Once you see the tree, select non-insulin dependant diabetes mellitus. Click on ‘take this to Disease search’. Point out ‘major focus’ option if users would like to limit their search to only records where the disease is of major importance and show on Disease Search form. Shoe quick and advanced limits.You can then add the subheading ‘disease management’. Check filters for drugs and study types.
