Embase: Excerpta Medica Database Guide
Menu:

Embase (Excerpta Medica Database) is a biomedical and pharmacological database produced by Elsevier B.V., containing more than 40 million records including articles from more than 8,500 journals published world-wide. It contains bibliographic records with citations, abstracts and indexing derived from biomedical articles in peer reviewed journals, and is especially strong in its coverage of drug and pharmaceutical research, pharmacology, toxicology and medical devices. This field guide provides scope of information specific to the Embase database.

Embase adds approximately 2 million records annually. The original Embase part of the databases contains around 30 million records, spanning from 1974 to present, from 6,100 journals. The MEDLINE supplement contains ca. 10 million records from 2,400 journals, with unique records from MEDLINE.

  • Weekly updates average close to 40,000 new records and approximately 25-30K records are updated each week
  • Records that enter the database as Article in-Press will be overwritten by In-Process status records and will complete indexing as status Embase, or status MEDLINE records
  • Status Embase records (Fully-indexed) will average 20K records per week, complemented with approximately 10K NLM supplied records per week
  • In addition Elsevier processed around 300K Conference records over the past years, an average of 6K records per week.
  • Starting November 2021 Elsevier also started to add PrePrint status records to Embase from MedRxiv and BioXriv, that average around 1K/week

Each Embase record contains the full bibliographic citation, indexing terms, and codes; and 80% of all citations in Embase include author-written abstracts. The Embase journal collection is international with peer-reviewed journals from more than 90 countries.

Coverage focuses on the following core topics (with significant overlap between topics) representing over 70% of Embase content:

  • Pharmacology and toxicology
  • General clinical medicine
  • Genetics, biochemistry & molecular biology
  • Neurology & behavioral medicine
  • Microbiology & infectious disease
  • Cardiology & hematology
  • Psychiatry & mental health
  • Oncology
  • Healthcare policy & management
  • Allergy & immunology
  • Pediatrics
  • Endocrinology & metabolism
  • Obstetrics & gynecology
  • Biomedical engineering & medical devices
  • Anesthesiology & intensive care
  • Gastroenterology
  • Respiratory medicine
  • Nephrology & urology
  • Dermatology
  • Geriatrics & gerontology

For subscribers to the French Local Literature Module (EFLM):

The French Local Literature Module is a biomedical and pharmacological database produced by Elsevier B.V. and uniquely available as an addition to the Embase - Excerpta Medica Database, to allow pharmacovigilance groups align the monitoring of French-language literature for adverse drug reactions. The database is created from approximately 100 relevant French language journals identified based on input from industrial partners, the European Medicines Agency (EMA) and Agence Nationale de Sécurité du Médicament et des Produits de Santé (ANSM).
The content undergoes full-text human-supported machine translation from French to English. Original French titles and abstracts are kept and indexed for search and display. Translated articles are manually indexed with Emtree, and the full Embase search functionality is available for this database. The database is updated weekly and can be searched together with Embase, or as a separate database.

DJ Candidate Terms [Phrase Indexed]
active surveillance.dj.
 

The Candidate Terms (DJ) field is a new concept which is not in Emtree and was proposed during indexing because it was judged to be a useful addition to Emtree. This field is also indexed in the Subject Headings (SH) field.

Over 100,000 candidate terms are proposed each year, and the separate Candidate Terms (DJ) field therefore allows for identification of candidate terms. Please note candidate terms will not be picked up when mapping, and will not be available when browsing Emtree. Keywords searches (.mp) however will automatically pick up candidate terms from the Heading Word (HW) field.

1 1 2 triphenylethylene derivative.du.
 

The Drug Index Terms (DU) field contains index terms used for all drugs and chemicals: not only therapeutic drugs, but also endogenous compounds, laboratory chemicals and environmental chemicals or toxins.
It is important to realise that "drugs" as defined in Embase may refer to any chemical entity.

Index terms can either be manual or machine indexed. For Conference Abstracts the index terms are always machine indexed. For Embase/MEDLINE records it depends on the stage of indexing (Article in Press, Publisher, in-Process etc). For this reason a [m] suffix, e.g. ofloxacin [m]; will be added indicating when a term was derived by machine indexing. Typically status Embase and status PubMed/MEDLINE records are derived from manual indexing and will not have the [m] suffix.

Back 
DV Device Trade Name [Word Indexed]

Back 
EC Embase Section Headings [Phrase Indexed]
pharmacy.ec.
 

In addition to assigning index terms, indexers also classify articles to Embase section headings or classifications (e.g. Cancer or Surgery).

Each article is assigned to at least one such section heading. Normally, an article gets assigned to not more than five or six section headings.

ST Status [Phrase Indexed]
conference abstract.st.
 

The Status (ST) field contains the record status of the citation. It can be Conference Abstract, Article-in-Press, In-Process, or Embase record.

Conference Abstract: Abstracts of presentations provided during important biomedical, drug and medical device conferences dating back to 2009. Conference abstracts are published primarily in journal supplements from
journals that are selected for Embase. The source title usually includes words like proceeding(s), meeting(s), conference(s), symposium/symposia, seminar(s) or workshop(s), although some journals also include
proceeding(s) in the title.
Article in Press: Articles that have been accepted for publication but which have not been formally published and will not always have the complete volume/issue/page information yet. “Articles-in-Press” (AiP) are made
available in Embase within a few days after online publication, may lack full bibliographic detail, and an automated procedure is used to provide a provisional index of Emtree Subject headings for Article-in-press records.
The average time it takes before an AiP becomes a published article in a specific issue, can vary from weeks to months.
In-Process: In-Process records overwrite the AiP records, but they have not yet been fully manually indexed. Most documents proceed from an In-process state to a full Embase document, but if an article in press is never
formally published, it will remain in this status.
Embase: Embase status refers to fully indexed Embase records with Emtree subject headings and may have subheadings where applicable for drug, diseases and medical devices. They are indexed by subject matter
experts, and approximately 40,000 records with status Embase are added to Embase each week.

Note: Conference Abstracts, Article in Press and In-Process status records are automatically indexed with Emtree terms selected by an algorithm that is applied to the text of the titles, abstracts and author keywords. Automatically indexed Emtree does not have subheadings.

Records will either have an Embase Status (ST), or a NLM Status (NS). Please note that records recently added to the database can have Article-in-Press (ST) status as well as Publisher (NS) status at the same time. As Embase
records progress their indexing for Embase they will only have 1 status type (ST or NS).

Advanced Searching
You can use special search syntax listed below to combine search terms or strategically develop a search. Full documentation is provided in the Advanced Searching Techniques section of the Online Help.
Operator Syntax Search Example Sample Results
OR x or y vitamin c or ascorbic acid

"a statistically significant decrease in the plasma L-ascorbic acid concentration "

  The OR operator retrieves records that contain any or all of the search terms. For example, the search heart attack or myocardial infarction retrieves results that contain the terms heart attack, myocardial infarction or both terms; results are all inclusive. You can use the OR operator in both unqualified searches and searches applied to a specific field.
AND x and y anticancer and vitamin K

"Inhibition of rat liver regeneration after partial hepatectomy and induction of ERK phosphorylation by Cpd 5, a K vitamin-based anticancer compound. "

  The AND operator retrieves only those records that include all of the search terms. For example, the search blood pressure and stroke retrieves results that contain the term blood pressure and the term stroke together in the same record; results are exclusive of records that do not contain both of these terms. You can use the AND operator in both unqualified searches and searches applied to a specific field.
NOT x not y blastula not embryo

"while twitchin and myorod appeared at the blastula stage (12 h after fertilization).

  The NOT operator retrieves records that contain the first search term and excludes the second search term. For example, the search health reform not health maintenance organizations retrieves only those records that contain the term health reform but excludes the term health maintenance organizations. In this way, you can use the NOT operator to restrict results to a specific topic.
You can use the NOT operator in both unqualified searches and searches applied to a specific field.
Adjacency (ADJ) x y drug adj therapy

"Early ovarian carcinoma.....Surgical and drug therapy"

  The Adjacent operator (ADJ) retrieves records with search terms next to each other in that specific order. You do not need to separate search terms manually by inserting ADJ between them, because when you separate terms with a space on the command line, Ovid automatically searches for the terms adjacent to one another. For example, the search blood pressure is identical to the search blood adj pressure.
Defined Adjacency (ADJn) x ADJn y patterning adj3 embryo  

"Nodal signalling are all critical for proper patterning of the vertebrate embryo"

  The defined adjacency operator (ADJn) retrieves records that contain search terms within a specified number (n-1) of words from each other in any order (stop-words included). To use the adjacency operator, separate your search terms with ADJ and a number from 1 to 99 as explained below:

           ADJ1     Next to each other, in any order
           ADJ2     Next to each other, in any order, up to 1 word in between
           ADJ3     Next to each other, in any order, up to 2 words in between
           ADJ99   Next to each other, in any order, up to 98 words in between

For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship with a maximum of four words in between in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship between cancer patient and physician.
Please note Ovid’s order of operation handles terms within parentheses first. Therefore it is recommended to apply the ADJn operator in one-on-one operations to avoid missing out on results. E.g. stroke adj4 (blood pressure or high blood pressure) could potentially miss out on some combinations of stroke with high blood pressure. The optimum way to execute this on Ovid is: (stroke adj4 blood pressure) OR (stroke adj4 high blood pressure).
Frequency (FREQ) x.ab./FREQ=n blood.ab./freq=2

"To test this hypothesis, lactate concentrations in the whole blood, plasma and red blood cells of AS and AA were compared at rest "

  The frequency operator (FREQ) lets you specify a threshold of occurrence of a term in the records retrieved from your search. Records containing your search term are retrieved only if the term occurs at least the specified (n) number of times. In general, records that contain many instances of your search term are more relevant than records that contain fewer instances. The frequency operator is particularly useful when searching a text field, such as Abstract or Full Text, for a common word or phrase.
Unlimited Truncation ($) x$ rat$

"OBJECTIVE. To investigate apoptotic, degenerative, and inflammatory changes occurring in the cervical intervertebral discs of rats."

  Unlimited truncation retrieves all possible suffix variations of the root word indicated. To apply unlimited truncation to a term, type the root word or phrase followed by either of the truncation characters: $ (dollar sign) or * (asterisk). For example, in the truncated search rat*, Ovid retrieves the word rat as well as the words rats, and more.
Limited Truncation ($) x$n dog$1

"an intravascular ultrasound (IVUS) probe was placed in LCx in 29 dogs."
"and the response to HFS was blunted in one dog (10-11 V)."

  Limited truncation specifies a maximum number of characters that may follow the root word or phrase. For example, the truncated search dog$1 retrieves results with the words dog and dogs; but it does not retrieve results with the word dogma.
Mandated Wildcard (#) xx#y wom#n

"Inflammatory activity and anticardiolipin antibodies during tibolone treatment of healthy postmenopausal women. "
"We report the computed tomography features of a woman..."

  Searching with a mandated wildcard retrieves all possible variations of a word in which the wildcard is present in the specified place. You can use it at the end of a term to limit results to only those that contain the word plus the mandated character. For example, the search dog# retrieves results that contain the word dogs, but not those that contain the word dog, effectively limiting results to only those that contain the plural form of the word. The mandated wild card character (#) is also useful for retrieving specialized plural forms of a word. For example, the search wom#n retrieves results that contain both woman and women. You can use multiple wild cards in a single query word.
Optional Wildcard (?) xx?y colo?r

" one or more colours (95.5%)"
"in addition to the predictable red hair color (RHC) alleles"

  The optional wild card character (?) can be used within or at the end of a search term to substitute for one or no characters. This wild card is useful for retrieving documents with British and American word variants since it specifies that you want retrieval whether or not the extra character is present. For example, the optional wild card search colo?r retrieves results that contain the words color or colour. You can use multiple wild cards in a single query word.
Literal String ("") "x / y" "Heat / Cold Application"

"Patient education, psychological support, weight control, exercise, heat/cold application, and... "

"n" "3".vo

"Foodborne Pathogens & Disease. Vol. 3(2)(pp 212-215), 2006. "

 

Quotation marks can be used to retrieve records that contain literal strings, when the string includes special characters, such as a forward slash (/).

Quotation marks can also be used to retrieve records that contain numbers that may otherwise be confused for earlier searches. In the example, a search for 3.vo would limit the string from your third search in your search history to the volume field. By including the number in quotation marks, the search will retrieve documents with a 3 in the volume number.

Go: Menu or Back 

 

Stopwords
The Ovid search engine applies so called "run-time stopword processing". This means the search engine on the fly ignores the stopwords: and, as, for, from, is, of, that, the, this, to, was, were.

Therefore a search: at risk for diabetes.ti will also find: at risk of diabetes. The distance of one word in between is kept, but the stopword "for" is ignored.

Records From

Sentence Syntax: limit 1 to medline
 

A limit of Records From will restrict retrieval to documents collections as defined by Elsevier.

Embase (records indexed by Embase and are Elsevier copyrighted; these records may also have been indexed separately by MEDLINE)

MEDLINE (records identified as uniquely MEDLINE and have not been indexed by Elsevier)

Conference Abstract (records identified as uniquely Conference Abstract and are Elsevier copyrighted)

Preprints (unpublished, non-peer reviewed) (records identified as uniquely PrePrint and are Elsevier copyrighted)

Remove Preprint Records

Sentence Syntax: limit 1 to "remove preprint records"
 

Allows to remove preprint records from the search results. Preprints are preliminary reports of work that have not been certified by peer review. Embase is using MedRXiv and BioRXiv as the source for PrePrint records.

Remove MEDLINE Records

Sentence Syntax: limit 1 to remove MEDLINE records
  This limit removes all records that have a PMID in the PM field. Please note that records in Embase are indexed with Emtree and feature other Embase-specific fields that aren't available in Ovid MEDLINE/PubMed. If you just want to remove the "unique for MEDLINE" records, we recommend that you use the "Records From" limit.

Retraction Notice

Sentence Syntax: limit 1 to retraction notice
 

A limit to Retraction Notice will restrict retrieval to all articles the Publisher announced are no longer valid, and for which the Embase record is updated accordingly

Routes of Drug Administration

Sentence Syntax: limit 1 to oral
  Routes of Drug Administration are the various ways in which drugs may be administered, such as "intramuscular" or "regional perfusion." If you choose Routes of Drug Administration... you will be presented with a comprehensive list from which to select.

Source Types

Sentence Syntax: limit 1 to conference proceeding

Special Ovid Filters for Embase

Sentence Syntax: limit 1 to Adverse Effects - focussed
limit 2 to Children
 

You can use Special Ovid Filters to restrict retrieval to a pre-defined set of records, populated by a special Ovid search strategy for that topic. As the results sets for these filters are created with every database update, the results display quickly. Ovid filters are "AND" combined with the search line you are trying to limit, unless stated otherwise (e.g. humans only).

Each of the search hedges below are based on publicly available filters that have been reviewed, translated, and improved by Ovid expert searchers. While these filters aren't validated by Ovid, we provide the full transcript for each filter below and we have placed a reference for each filter where applicable. You may want to review the underlying terms and modify them as necessary.

Ovid welcomes your suggestions to enhance the filters. Please contact [email protected].

Abstract:
	Intra-hospital transfers (eg to CT/MRI/angiography suite) for Level 2 and Level 3 inpatients on critical care units at Kings are 
    	carried out by airway trained doctors and accompanied by nursing staff. Currently no pre-transfer checklist exists and we felt that 
    	developing such a checklist could improve the safety of the transfers by ensuring staff can be confident that equipment and 
   	medication required to make the transfer is available if required. There was also no clear system for how regularly, and by whom, 
   	the contents of the transfer bag were checked and it was carried out on an ad hoc basis. We surveyed 33 members of the 
  	medical and nursing staff working across critical care units and Kings College Hospital to evaluate whether they felt the safety of 
   	transfers could be improved. 73% of those surveyed were not aware of how often the transfer bags were checked, only 49% 
   	stated that if equipment was needed quickly it would be easy to find with the other 51% describing it as 'difficult' or 'very difficult' 
    	and 97% of those surveyed stated they thought a checklist to go through prior to each transfer would improve the safety of the 
   	transfers. A snapshot inspection of a number of the transfer bags found there to be no checking system in place with some 
   	expired items. The issue surrounding checking of the transfer bags has been rectified immediately with regular checks 
    	introduced. We have developed a short checklist to be filled out prior to intra-hospital transfers so that staff who do not work 
    	regularly together or are new to the trust can be confident that all essential equipment and drugs are in-date, available and have 
    	knowledge of their whereabouts if required in an emergency. The checklist will be implemented shortly and it's use will be re-
    	audited in the coming months.

Abstract:
	Introduction: Literature has shown that Benzodiazepines affect males and females differently for various reasons. We analyzed 
   	males and females on CIWA (Clinical Institute Withdrawal Assessment for Alcohol) protocol and studied their outcomes, 
   	benzodiazepine dosage, ICU length of stay (LOS) and hospital LOS. Methods: A retrospective observational hospital study in an 
   	adult ICU at an academic community hospital in an urban setting was administered with a total patient population of 56 
   	individuals. The groups were divided based on gender, male (n=46) and female (n=10). Subsets were compared using mean 
    	benzodiazepine dose, ICU LOS and hospital LOS. Results: The mean benzodiazepine dose was higher in the female patient 
    	population compared to male population (64 mg vs 28 mg, p-value=0.05). The mean ICU LOS was also higher in the female 
    	population compared to the male population, with a notable statistical significance (12 days vs 4.0 days, p-value=0.05). The 
    	mean hospital LOS was also higher for the female group when compared to the male group (13 vs 8 days, pvalue =0.05). 
    	Conclusions: There was a significant difference in the amount of benzodiazepine administered on the female patient population, 
    	which appears to have affected their ICU LOS and hospital LOS. The results are not entirely conclusive, due in part to the 
    	disproportionate gender representation and overall small number of patients.
