Adverse Effects, Drug-Induced
PDF of this tip
When searching for a specific drug-induced adverse effect, combine a drug term in the
Drug
field with a free-text truncated keyword in the
Title or
Abstract fields, e.g.
Drug:
clozapine,
Title or
Abstract: "
agranulocy*".
If this does not find the information you want, try a broader search by combining the drug term
with an appropriate side effect descriptor, e.g.
Drug:
clozapine,
Descriptor:
"SIDE EF HEMIC LYMPHATIC 83".
A common mistake when searching for drug-induced adverse effects is using the
Disease
field to search for the specific disease or condition induced by the drug. Combining drug and
disease search terms pulls articles in which the drug was used to treat the specified disease or
was used in a patient with that disease.
AHRQ Documents
Searching the Journal field with AHRQ EVID REP or AHRQ COMP EFF REV
will retrieve Evidence Reports or Comparative Effectiveness Reviews (respectively). Searching
with only AHRQ in the Journal field will pull both AHRQ Evidence Reports
and AHRQ Comparative Effectiveness Reviews. These are high-quality systematic evidence-based
reviews sponsored by the United States Agency for Healthcare Research and Quality (AHRQ).
AHRQ is the lead Federal agency for the United States research on health care quality, costs, outcomes,
and patient safety.
Allergenic Immunotherapy
Articles related to immunotherapy in the context of allergenic desensitization are indexed under
DESENSITIZATION, ALLERGEN V07.1 not PROPHYLAXIS, IMMUNOTHERAPY V07.2.
Complementary and Alternative Medicines
Complementary and alternative medicine articles are indexed in the database and can be found
by searching a specific herbal or one of the following drug terms: CHINESE HERBAL MEDICINES
92510129 , HERBAL MEDICINES 92510000, HOMEOPATHIC PREPARATIONS 92000210 when
the article does not focus not on a specific herbal product.
Drug Interaction
PDF of this tip
When looking for reports or studies of drug interactions, combine two drug terms with descriptors "DRUG COMBINATION 16"
and "DRUG INTERACTION 50."
Drug: "ST JOHN'S WORT" and "ROSUVASTATIN"
Descriptors: "DRUG COMBINATION 16" AND "DRUG INTERACTION 50"
A broader, follow-up search to the one above is to drop the descriptor terms and combine the two drug terms with
a free-text search in the title and/or abstract with any pertinent keywords related to the drug interaction.
Drug: "ST JOHN'S WORT" and "ROSUVASTATIN"
Title or Abstract: "interact*"
Editorials
How do I limit my search to editorials?
To limit a search to editorials, include "editorial" in the Author field.
Erratum
PDF of this tip
How can I find if an article has an erratum or other type of correction?
The
IDIS database allows you to find corrections to the original articles already in the
database. The corrections are submitted by the original author(s) or the journal publisher.
Articles that contain corrections have
"CORRIGENDUM Z100." as an
IDIS disease term.
The corrigendum term includes articles that are erratum, addendum, retraction or note of plagiarism. The type of
correction is listed in the title field followed by the article number for the original article or correction.
For example:
Article Number: 671736
Title: THE ROLE OF STEROIDS IN TREATING SEPTIC SHOCK (ERRATUM) (ART 675412)
In this example the original article is 671736 and the erratum is article 675412.

FDA Advisory Committee Meeting Updates
PDF of this tip
Information from individual FDA Advisory Committee meetings is posted sporadically on the FDA web site.
People unfamiliar with the postings of the FDA Advisory Committee meetings may not realize that information
from a given meeting may be missing or not yet posted as there is currently no notice on the web site to alert
users of pending or missing postings. It is often several months between the time the Meeting Notice and Briefing
Information are posted and the meeting Transcript, Slides and Summary Minutes are posted. Errata to Briefing
Information and the Transcript also occasionally appear.
We continually monitor 17 FDA Advisory Committees updating the
IDIS database with the information from these
meetings as it becomes available. We occasionally contact the FDA officers in charge of the various meetings when
meeting postings are missing or slow in appearing.
Information from FDA Advisory Committee meetings is easily found in the
IDIS database with descriptor "FDA
ADVISORY COMMMITTEE 164." The FDA Advisory Committee name and date of meeting are included in the Title of each item from a
meeting, e.g. "SUMMARY MINUTES. ONCOLOGIC DRUGS ADVISORY COMMITTEE MEETING, OCTOBER 5, 2009." In
IDIS, FDA Advisory
Committee meeting items typically include: Notice of Meeting, Waivers of Conflict(s) of Interest, Briefing Information
from Drug Sponsor, Briefing Information from FDA, Questions to the Committee, Transcript and Slides, and Summary Minutes.
FDA Advisory Committee Meetings
PDF of this tip
FDA Advisory Committee meeting documents may be found by searching
Descriptor:
FDA ADVISORY COMMITTEE 164.
Advisory committees often review and discuss the pivotal drug trial(s) of investigational
new drugs and submit their opinion of the safety and efficacy of the drug to the FDA. Meetings
discussing post-marketing safety and efficacy of FDA Approved drugs are also common.
Briefing Information from Drug Sponsor, Briefing Information from FDA, Transcript and Slides,
Summary Minutes, and Notice of Meeting are the most common documents made available from an FDA
Advisory Committee meeting.
FORMULATION EFFICACY Descriptor
PDF of this tip
When looking for information on delayed-, time-, sustained-, or extended-release drug products, descriptor
"FORMULATION EFFICACY 22" is a helpful descriptor to include in a search statement. Combining this descriptor
with a drug term will narrow the search to include articles in which formulations other than the immediate-release
or standard product are discussed. One author may refer to it as "sustained-release" whereas another may refer to
it as "delayed-release" in the published literature. Descriptor "FORMULATION EFFICACY 22" will ensure that both
scenarios are retrieved.
Guideline Adherence
Articles concerning adherence to guidelines, or use of guidelines, are indexed with the combination of descriptors GUIDELINES 156 and DRUG UTILIZATION 128. To retrieve these articles, either enter the descriptor numbers into the Descriptor field (156 and 128), or use the autosuggest or Look Up feature to select and submit these descriptors. Descriptor Look Up can be accessed by clicking on the Descriptor field label.
Immunization
PDF of this tip
Articles related to both active and passive immunization are included in the database.
Active immunization:
The defined disease term for "active immunization" is
"INOCULATION AND VACCINATION 99.3". A search combining
"INOCULATION AND VACCINATION 99.3" and a defined disease term for a specific infection and the Boolean operator "
and" in the
Disease field retrieves articles related to immuno-preventive therapy for a specific infection, e.g.:
Disease field:
"INOCULATION AND VACCINATION 99.3" and "HEPATITIS, VIRAL B 070.2"
Passive Immunization:
The defined disease term for "passive immunization" is
"PROPHYLAXIS, IMMUNOTHERAPY V07.2". A search combining
"PROPHYLAXIS, IMMUNOTHERAPY V07.2" and a defined disease term for a specific infection and the Boolean operator "
and" in the
Disease field retrieves articles related to passive immunization therapy for a specific infection, e.g.:
Disease field:
"PROPHYLAXIS, IMMUNOTHERAPY V07.2" and "HEPATITIS, VIRAL B 070.2"
Lactation
How do I search for articles about drugs used in lactation?
To search for articles about drugs used in lactation, enter the valid drug term(s) in the
Drug field and use the LACTATING MOTHER V24.1 check tag in the Disease
field.
Letters to the Editor
How do I limit my search to letters to the editor?
To limit a search to letters to the editor, include "letter to ed" in the
Author field.
Logging Off
Remember to click on the "Log Off" link in the top menu bar of IDIS Drug Database before closing
your web browser. If you forget to log off,
the system will timeout the connection after 20 minutes of inactivity.
NICE Documents
Searching the Journal field with NICE CLIN GUIDEL or NICE TECHNOL APPRAISAL GUID will retrieve
Clinical Guidelines or Technology Appraisal Guidance (respectively). Searching with only NICE in the Journal
field will retrieve both NICE Clinical Guidelines and NICE Technology Appraisal Guidance documents. These
are high-quality systematic evidence-based reviews from the National Institute for Health and Clinical Excellence (NICE).
NICE guidance is developed using the expertise of the National Health Service (NHS) in England and Wales and the wider
healthcare community including NHS staff, healthcare professionals, patients and carers, industry and the academic world.
Pharmacoeconomics
PDF of this tip
How can I find articles that deal with the economic issues of drug therapy?
Six economic outcome descriptors were added to the
IDIS database in November 1993. The
descriptors are:
ECON DRUG ECONOMICS 129
ECON COST BENEFIT 130
ECON COST EFFECTIVENESS 131
ECON COST MINIMIZATION 132
ECON COST OF ILLNESS 133
ECON COST UTILITY 134
The economics descriptor terms begin with
"ECON" followed by the study type.
The pharmacoeconomics definitions are based on the criteria of Luce & Elixhauser and consider drug
intervention cost and consequence measurements. Intervention costs are measured in monetary values,
but the measurement of the consequences differentiates the study types. Detailed definitions for
each economics descriptor may be found in
Descriptor Definitions, a link on the left-hand
side of the main search screen.
Pivotal Studies and FDA Advisory Committee Meetings
PDF of this tip
The purpose of many FDA Advisory Committee meetings is to discuss the safety and efficacy of new drugs that are
under review by the FDA for approval. Before an FDA Advisory Committee meeting, the Drug Sponsor and the FDA provide
Briefing Information on the proposed new drug. The pivotal studies, the studies the drug sponsor believe prove the safety
and efficacy of their product are very often contained in the
Briefing Information from the Drug Sponsor and
the
Briefing Information from the FDA. Documents related to FDA Advisory Committee meetings, including the
Briefing Information, may be found in
IDIS by using descriptor FDA ADVISORY COMMITTEE 164 in conjunction with a drug
term or other search terms. Note that not all drugs submitted to the FDA for approval are discussed at an FDA Advisory
Committee meeting.
Pivotal Studies in Three Formats
PDF of this tip
If a new drug or biologic is approved by the United States Food and Drug Administration (FDA), the pivotal studies
that appeared in the FDA Advisory Committee Briefing Information often appear again in the Medical Review(s) and Statistical
Review(s) sections of the FDA Approval Package for the drug. There may be differences in the information due to different
reviewer analyses.
Some of the pivotal studies, although not all, are also published in journals. Therefore, it is sometimes possible to find 3
different write ups or reviews of the data from a pivotal study.
Population Tags
Use of "population tags" will limit a search to articles relating to drug use in a
particular population, such as in pregnancy, in athletes or in a particular age group. Enter the
relevant tag into the
Disease field of the search Home search page or select age populations from the Search Limits section of the Home search page.
The population tags are:
V22. Pregnancy NEC
V28. Fetus: In Utero
V39. Neonate: Newborn to 4 Wks
V85. Pediatric: 1 Mth to 12 Yrs
V21.1 Puberty and Adolescence: 13 to 19 Yrs
V86. Geriatric:65 Yrs and Over
V87. Race
V88. Athlete

Searching with Drug and Disease Terms
PDF of this tip
In the
Drug and
Disease Fields on the Home search page you may enter any drug or disease and it will automatically be cross-referenced and searched for you. In doing so, however, you are likely to get hits that make you scratch your head and wonder why. This is because of the cross-referencing. Therefore, to get the cleanest, most exact searches, you should rely on the autosuggest feature to help you find the valid indexing terms. You can also use the field
Look Up feature (accessed by clicking the field label) or the
Thesaurus located in the
Search Tools section on the right side of the search page. Using the
Look Up or
Thesaurus will help you find the exact drug, disease and descriptor terms to use in your search. In the
Thesaurus drug terms are preceded by DR, disease terms by DI and Descriptors by DE.

Vaccines and Cancer
Articles related to the use of vaccines in the treatment of cancer (BCG vaccine for bladder
neoplasm for example) can be retrieved by conducting a search with the defined disease term
corresponding to the neoplasm in the disease field and the defined drug term corresponding to
the vaccine in the drug field without the disease term INOCULATION AND VACCINATION 99.3.
This disease term is reserved for a true vaccine with a focus on the prevention of disease.
