Clinical Research Participants
Clinical trials require different types of people. Each type chooses to participate for different reasons.
- Healthy Volunteers
Healthy volunteers play an important role in research because they help define “normal” ranges. While they may receive no direct benefit, healthy volunteers may choose to participate in clinical research because they want to help others and contribute to advancing science.
- Patient Volunteers
People with a health condition or disease may take part in a research study to gain access to a new therapy; take a more active role in their health; or contribute to better understanding, diagnosing, or treating that disease or condition. While some patient volunteers may receive a direct benefit from participating, the overall goal of the clinical trial may be to understand the risks and benefits of a treatment and to scientifically prove whether it is effective.
Who Can Participate?
Researchers use a list of rules called eligibility criteria to decide who is eligible to be in the study. These criteria ensure it is safe for you to participate. They also ensure the study results are due to the treatment being studied and not other factors or chance.
“Inclusion criteria” are factors that allow someone to be included in the study. “Exclusion criteria” are factors that disqualify someone from being in a study. These factors can include:
- Type and stage of a disease
- Previous treatment history
- Other medical conditions
Deciding to Volunteer
There are different ways to participate in clinical research. You may need to visit the hospital, doctor's office, or nursing home. Or you may participate in a classroom, in your own home, or through an online survey or questionnaire. Types of participation can include:
- Completing a questionnaire about health or behaviors, or answering questions in an interview with researchers
- Donating a tube of blood or a tissue sample
- Taking part in a clinical trial to find out if new therapies are safe and effective
- Helping researchers understand how the healthy body works
Our doctors and providers offer many opportunities for you to participate in clinical research.
Understanding the Risks
Clinical research can have risks, just like routine medical care and the activities of daily living. While some of the risks are minor, other risks are more serious. Some clinical research participants may experience complications that require medical attention. It is rare for people to be seriously injured or die from complications related to clinical trial participation. When considering whether to participate in a clinical trial, it’s important to understand:
- The possible risks of being in the study
- The level of risk or harm
- The chance of that risk or harm happening
Where to Find the Risks
The risks of a specific research study are described in detail in the informed consent form and will be explained to you by the study team. The study team will also explain the purpose of the study and what will happen while you are in it and will answer any questions you have.
Questions to Consider Before Volunteering to Be in a Study
Educating yourself about the study and its risks and benefits will help you determine if participation in a clinical trial is right for you. The research team should be able to answer your questions before you decide.
While every study is different, here are some general questions you will want answers to before you decide. Most of this information will also be in the informed consent document you will need to sign before you join a study. You can also download a PDF of the questions below and print it before you meet the study team.
- What’s the condition being studied?
- What is the main purpose of the study?
- Why is this study being done?
- Why is it important?
- Why is the study needed and what important questions will it answer?
- If this is a clinical trial, what phase is it?
- Why do researchers believe the treatment being tested may be effective?
- Has it been tested before?
- What were the results of earlier studies of this treatment?
- How likely are those results to apply to me?
- What treatments will I receive during the study?
- How do they compare with what I would receive if I don’t join the study?
