Talking to your doctor
How to bring a study up with your own doctor, and what to ask them.

Your own doctor knows your health better than any study team will on day one. Bringing them into the decision is almost always worth it.
Why involve your doctor
A study may ask you to pause or change a medicine, add tests or follow a schedule for months. Your doctor can tell you how that fits with the rest of your care, and whether anything about your health makes a particular study a poor idea. Many research teams also ask for permission to contact your doctor, or to see your records, during screening.
How to raise it
You do not need to have decided anything first. A simple opening is enough: “I have heard about a study for my condition and I would like your view.” Bring whatever the study team has given you, such as a summary, a consent form or the study’s registry number, so your doctor can look it up.
What to ask
- Is there anything about my health that makes this study a risk for me?
- How would the study change the treatment I have now?
- Would you be willing to share my records with the study team if I agree?
- Who should I call if something comes up between study visits?
If your doctor is unsure
Not every doctor knows much about research, and some are cautious about it. That is fine. Ask whether they can talk to the study’s investigator directly; research teams are used to these calls and usually welcome them. The final decision is still yours.
During the study
Keep your doctor informed about what you are taking and how you feel. Tell the study team about any appointment, new medicine or hospital visit outside the study, and tell your doctor about anything the study changes. Both sides need the full picture to keep you safe.
