Ethics in Medical Research Flashcards
What are the differences between medical research and clinical care?
- Research and care have different goals
- medical research costs a lot of money
- Past harms
- You may care for a patient who is also a research volunteer
Research and care have different goals:
The clinical care goal focuses on patient outcomes, curing patients, and making them comfortable
The medical research goal focuses on knowledge, and finding cures
Medical research costs a lot of money:
There is a possibility of corruption*
When drug trials aren’t effective, it is possible companies will alter their results to have better outcomes so they can compensate for the financial loss
Past harms:
Falls under restitution, one of the prima facie duties ?
You may care for a patient who is also a research volunteer:
- Patients may be participants in clinical trials
- Nurses may or may not know, patients may or may not know
- Nurses can also be involved in a clinical trial
What is REB?
It is the research ethics board
- It is all federally funded research in Canada must get approval before proceeding with the clinical trial
What about privately funded research?
If private research is being trialled in a publicly run facility, it should be approved by an REB
What is the “Gold Standard” for testing medications?
Randomized Controlled Trial (RCT)
- It compares variables (patient outcomes)
What are the other options for comparison in medical research ?
- Investigational treatments (experimental drugs)
- Existing medications
- Placebo
- No intervention (observations)
What are comparisons referred to?
They are called an “arm”
2 arm = compares 2 of the options
3 arm = compares 3 of the options
What are the 4 phases of clinical trials?
- Dosage
- Safety
- Efficacy
- Post-Marketing
Phase 1: Dosage
How we find out how much of a drug should be given and when it becomes toxic
- Small number of volunteers that are healthy
- Uses a placebo
- Starts with a small amount of medication on a small group of people, increasing amount on a new group of people
Phase 2: Safety
Repurposed drugs get a pass on phase 2
- There is a slightly larger trial that still uses healthy volunteers
- There can still be a placebo
- No SAE (serious adverse event)
- Ensures there are no long lasting side effects*
Phase 3: Efficacy
Efficacy is a statistical measurement, not how effective sometime is*
- This trial is as big as possible, and tests on sick participants
- There is no placebo (means leaving sick people unmedicated which is unethical*)
Phase 4: Post-Marketing
The drug is out there, Dr.’s are prescribing it, and people are taking it
- There is more potential for side effects to appear in the public because not all side effects are going to show up in smaller clinical trials
- Dr.’s are supposed to inform Health Canada when patients report side effects
- Consumers can report side effects to the Canada Vigilance Program
