References, so why do we need them? • There is too much information for one person to know. • References provide a way for healthcare professionals to gather and verify information to better serve the healthcare community. • Information is changed or updated frequently. • References provide a resource to pharmacy staff to keep up-to-date on current medical information without constantly having to relearn and memorize data.

  3. Objectives • To become familiar with the references commonly used by various healthcare providers. • Demonstrate where to find specific pharmacy information in the available resources. • To identify a reliable source when presented with multiple sources. • Become familiar with various methods of citing information found in various source.

  4. More Objectives….. • Be familiar with the kind of information available. • List the different kinds of information found in different sources. • Identify situation in which you would use each of the resources covered in this chapter. • Describe the role of the internet in performing medical research. • Describe the role of journals and professional newsletters in research.

  5. And ….. • Be able to describe the information found in: • American Hospital Formulary Service Drug Information • Drug Topic’s Red Book • FDA Orange Book • Drug Facts & Comparisons • Goodman & Gilman’s: The Pharmacological Basis of Therapeutics. • Handbook of Injectable Drugs • Ident-a-Drug • Physician Drug Reference (PDR)

  6. Oh Wait! Don’t forget……. • Monograph • USP DI (United State Pharmacopeia Drug Information) • Smaller Summary PDR’s (Such as the one from Mosby’s) • Remington’s Pharmaceutical Sciences: The science and Practice of Pharmacy • Martindale's • Micromedex • LexiComp • Various Brand & Generic Reference’s

  7. Terminology • Primary Source • Secondary Source • Tertiary/Secondary Source • Chemical Name • Nonproprietary Name • Generic Name • Brand Name • Monograph • FDA • USP • AWP

  8. And more terminology…. • Indications • Contraindications • Side Effects • ADE or ADR • NDC • NCPDP • SRP • UPC • Formularies

  9. Using References & Reference Material The ins & outs. The “how to” and “how not”

  10. Warning NO REFERNCE IS A COMPREHENSIVE RESOURCE. SOME SOURCES ARE BETTER THAN OTHERS, BUT NO SINGLE RESOURCE IS PERFECT.

  11. Types of Information Available • Scientific Research • Clinical Trials • Monograph • Summarized Studies (aka Meta-Analysis) • Summaries • Extracted Data (Tables, Lists, Charts) • Definitions (Dictionaries)

  12. Scientific Research • Research typically done in labs & controlled studies. • Kinetic Data • Pharmacologic Information • Typically found in peer reviewed journals. • Used most often in clinical pharmacy or in a research or educational setting.

  13. Clinical Trials • Any situation where a patient is used as a test/study participant. • Many Different Types • Typically NOT done in: • Oncology (Chemotherapy) • Pregnancy • Pediatrics • Or with any highly toxic medication.

  14. Types of Clinical Trials • Randomized: Participants are assigned treatment or placebo randomly. • Blinded: The patient is does not know if they are receiving the active treatment or placebo. • Double-Blinded: Neither the patient nor the healthcare team knows who in the study is receiving the active treatment or placebo. • Meta-Analysis: A study of Studies. • Retrospective: Looking back at past Data.

  15. Clinical Trials Hierarchy • Randomized, Double-Blind • Randomized, Blinded • Randomized • Case-Control • Cohort • Case Study • Allegorical Meta-Analysis

  16. Stages of Clinical Trials • Preclinical: Lab work, establishes preliminary data; not done in humans. • Stage I: 20-80 healthy participants, determines safe range and side effects. • Stage II: 100-300 participants, includes healthy and target population, determines early efficacy and also validates safety data. • Stage III: 1,000-3,000 participants, confirms efficacy, safety, ADRs, comparison to other available treatments. • Stage IV: Post-marketing, gathers additional information, typically finds effects only seen in a small population or that rarely occur.

  17. The Drug Monograph • Information approved by the FDA • Includes: • Brand Name (Assigned by manufacture) • Generic Name (Assigned by FDA) • Pharmacology • Pharmokinetics • Black Box Warnings • ADR/Side Effects • Found in PDR or with Stock Prescription Bottle • Does not include off label uses.

  18. Summarized Studies • Summaries of clinical trials and research. • Uses statistical models to extrapolate data. • Typically used in research, clinical, and educational settings.

  19. Summaries • Readily Available • Summaries of published data. • Used frequently in pharmacy practice. • Type of practice setting will determine type of summary resource used. • Updated frequently • Examples: • Facts & Comparisons • Handbook of Injectable Drugs

  20. Extracted Data • Tables, Charts, Lists • Benefits: Small, Portable, Easy to handle and Reference. • Negatives: Small amount of information, not a comprehensive resource. • Updated often. • Example: • Brand-Generic References • LASA Drug Lists • Protect from light lists.

  21. How Information is Organized!

  22. “A rose by any other name……” Medications come by many different names. Different references will list the medications by different names. • Chemical Name • Nonproprietary Name • Brand Name • Abbreviations • Colloquial names

  23. How Information is Organized • Alphabetically by name. • Therapeutic Class • Diagnostic Class • Mechanism of Action (MOA) • Manufacture

  24. Before you start……. • What are you looking for? • How much detail do you need? • For whom are you preparing the information? (or who is your audience?) • What sources do you have available? • How much time do you want to spend looking?
