Learning Goals

To understand the magnitude of health information available today

To be able to classify questions as background or foreground

To understand the differences between primary, secondary, and tertiary resources

To be able to determine ultimate questions and classify them by drug information type

To be able to use Drug Facts and Comparisons, Epocrates, Lexi-Comp, Micromedex, and Clinical Pharmacology

For a drug information question, which would you consult?

List a pro and a con for each resource.

Journal

Textbook

background questions
Background Questions

Question is broad in scope

Answer is general knowledge in field

Can best be addressed with tertiary resources

E.g. Is a drug available in the U.S.?

What is a drug’s mechanism of action?

When is a drug contraindicated?

foreground questions
Foreground Questions

Question is narrow in scope

Answer may require examining new or conflicting evidence

Can best be addressed with secondary and primary resources

E.g. How effective is a new drug when compared to

drugs that are already on the market?

Are there clinical trials supporting an off-label use of a

drug in a specific population?

slide10

Resource Types:

Primary

Secondary

Tertiary

primary resources
Primary Resources

Scientific journals

Provide original studies or reports

E.g. Clinical trial, case series, case report

Good for foreground questions

Scope is narrow

Good when topic is new or new data has been published

primary resources12
Primary Resources

Pros:

Most current evidence

Provide data on new drugs

Can personally assess validity of studies

Cons:

May not lead one to best decision because of limited scope

Data can be poor or controversial

Every study has limitations

Too complex for patients

secondary resources
Secondary Resources

Bibliographic databases that provide abstracts or full-text of studies

Good for foreground questions

secondary resources14
Secondary Resources

Pros:

Can construct searches to find specific information

at high granularity

Cons:

Often require more expertise to use than primary or tertiary

resources

Retrieved references must be filtered for quality

Must track down resources before looking for answers

Too complex for patients

tertiary resources
Tertiary Resources

Compilations of knowledge in the field

E.g. Textbooks, handbooks, online drug compendia

Good for background questions

Scope is broad

tertiary resources16
Tertiary Resources

Pros:

Provide comprehensive information

Information reflects views of multiple experts in field

Fast, easy to use, and may be good for patients

Cons:

Usually at least 2 years out of date by publication

High dependency on interpretation of authors**

**Pharmacists can address this by consulting at least

2 tertiary resources to find corroborating information

slide17
When trying to answer a clinical question, the best strategy is often to consult resources in the following order:

Tertiary, Secondary, Primary

Tertiary resources are good when:

The answer to a question is basic factual knowledge in the field

The question was studied extensively and a conclusion was made

Many experts have addressed the question and agree on answer

Secondary and primary resources are good when:

A question is new and has never been studied

There is no consensus among experts; various opinions abound

There is conflicting evidence and the question needs further study

determining the ultimate question
