Confirm the source
Start with the official study title, identifier, sponsor or institution, location, and current recruiting status. Online descriptions can become outdated. Contact an authorized site before making plans or changing care.
Share only what is necessary
An initial conversation may cover age, diagnosis, treatment history, medications, or location. It is not a final eligibility decision. Ask how information is protected and how records should be transferred securely if later requested.
Understand before agreeing
The team should discuss purpose, procedures, risks, possible benefits, alternatives, costs, payment, privacy, injury information, and contacts. You may ask questions, take time, and decline.
Eligibility is protocol-specific
Screening may include records, exams, laboratory work, imaging, or questionnaires. Ask which activities are research-only, whether results are returned, and whether costs are covered.
Follow the plan and report changes
Attend visits, follow study instructions, and promptly report symptoms, medication changes, or concerns. Keep urgent study contact details available. Continue ordinary care unless qualified professionals advise otherwise.
Know what continues
Safety calls, visits, data collection, or specimen storage may continue after the intervention. Ask when participation ends and whether overall results may be shared.
What changes from trial to trial
Some studies use random assignment, placebo, blinding, crossover periods, run-in periods, or dose escalation. Others do not. Compensation, travel support, remote participation, and access after the study also vary. Never infer these details from the phase or condition alone—ask the site to explain the exact protocol.
