Midterm Content Flashcards
What are the 7 steps in handling Drug Information Requests?
- Secure requester demographics
- Obtain necessary background information
- Determine and categorize the ultimate question
- Develop a strategy and conduct systematic search
- Perform evaluation, analysis and synthesis of information
- Formulate and provide a response
- Conduct follow-up and documentation
If a DI request is about a specific patient, what information should you obtain?
- patient name, weight, age, sex
- medical history
- major organ functions
- drug history
- history of allergy or adverse reactions
Where should the search of external information start for a DI request?
Tertiary sources first, then secondary, then primary
What should be included in a written response to a patient concerning a DI request?
- Summary of request and background information
- Response; clarify any terminology and include any inadequacies in findings in the literature
- Conclusion; summarize information and answer the request
- REFERENCES
What are the four steps in investigating drug information requests?
- Understand the diagnosis
- Understand the medication
- Understand patient specifics
- Tackle DI request
What are the desired characteristics of a response to a DI request?
- Timely
- Current
- Complete
- Concise
- Supported by the best available evidence
- Well-referenced
Should you report small effect sizes to patients when giving them a response to a DI question?
Yes, even small effect sizes are necessary information to give to a patient. If there was a surgery with a 97% rate but a 3% rate of major complications, depending on the patient they may make a different decision based on these results
Why is it important to document any DI request, no matter the severity?
- Allows coworkers to facilitate care if you are away
- Allows you to remember other options when “plan A” doesn’t work
- Allows you to remember the case if there is a follow-up later on
- Legal liability
What are the four aspects of a research study that define what method was used and their associated pros and cons?
- Nature of Research - Descriptive vs Explanatory
- Time frame of research - Retrospective/cross-sectional/prospective
- Investigator approach - Observational/experimental
- Type of Data - Quantitative/Qualitative
Define Administration
The giving of a therapeutic agent to a patient
Define Adverse Reaction
Any undesirable or unwanted consequence of a preventative, diagnostic, or therapeutic procedure or regimen
Define Compatibility
Able to be safely mixed, as in the case of blood for transfusion or drugs for simultaneous administration
Define Cross-sectional reserach
- captures data at a single point in time
- useful for determining the prevalence of current rug exposure or health behaviour in a population
Define Drug Information
Integration of locating, analyzing, applying and communicating information concerning drugs, usually for use by the person in a decision making role in patient management
Define Experimental Research
Investigator controls exposures that may influence an outcome of interest. Has 4 components:
- Manipulation by investigator
- Control
- Random assignment
- Random selection
Define Explanatory research
Research meant to explain rather than describe a phenomena
Define Observational research
Investigator does not influence the exposures but tracks their natural course/progression
Define Pharmacodynamics
The study of how a drug acts on a living organism, including the pharmacological response and duration and magnitude of response observed relative to the concentration of the drug at an active site in the organism
Define Pharmacokinetics
The study of action of drugs within the body which can be envisioned more accurately as the actions of the body on an administered drug; includes mechanisms of drug absorption, distribution, metabolism, excretion, onset of action and duration of effect
Define pharmacology
Field studying the characteristics, effects and uses of drugs and their interactions with living organisms
Define Pilot
Small-scale preliminary studies to see if an intervention is feasible or worthwhile to do a full study on; not designed to draw conclusions from
What are some pros and cons of a prospective time frame in a study?
Pro: investigator controls quantity/quality of data
Con: more expensive and more time consuming
Define quasi-Experimental research
Looks like experimental research but it does not randomly assign subjects to a group
What are some pros and cons to a retrospective time frame in a study?
Pros: quick and inexpensive
Cons: cannot control the quality of data collected
What is the difference between internal and external evience?
Internal - knowledge acquired from formal education and training
External - accessible information from research
What are the 6 steps in the evidence based decision making approach?
- Transformation of a clinical problem into smaller part questions to investigate
- Answer the questions based only on internal evidence
- Find external evidence to answer the question
- Critically appraise the external evidence
- Integrate internal and external evidence
- Evaluate decision making process by considering the process and outcome as opportunities for improvement

- could be the only source of information on a new drug/rare diseases
Limitations:
- possible flaws in study methodology

- good for getting background info
- easy to use
Limitations:

- may not be most current (excluding drug databases)
- hard to see if authors used the ‘right’ sources and whether or not they appraised their literature
When would be an appropriate time to consult secondary and primary literature?
New and emerging topics; no consensus among experts; conflicting evidence; question requires further study
What is a systematic review and what is the quality level of this evidence?
A thorough search of the literature, screening of studies to see if they are similar enough to compare and then vigorous analysis and appraisal of individual studies

What is a randomized control trial?
Experimental study design introducing an intervention to modify course of disease
–> patients are randomly assigned to an intervention or control group and then followed forwards
What is a cohort study?
Patients with a specific exposure are followed forward in time and compared to a similar group which has not been effected by the exposure
What is a case control study?
Patients with and without a specific condition are compared by the researchers to identify which exposures have contributed to the condition
“Looking back”
What is a case series/report?
Collections or reports/report on the diagnosis, treatment and follow up on a small group of patients or single patient
–> useful for calling attention to an unusual association, adverse event or a rare disease
