Visual summary for Decentralized Clinical Trials: What Patients Should Ask

The short answer

A decentralized or hybrid trial may reduce travel, but patients still need clear answers about safety monitoring, local testing, privacy, costs, scans, and emergency contacts.

  • A decentralized or hybrid clinical trial uses some remote or local steps, such as telehealth visits, local labs, home symptom reporting, or fewer trips to the study center. It may still require in-person care.

  • The safest next step depends on diagnosis, treatment, symptoms, test results, and the care team's instructions.

  • Use this page to prepare questions and decide what information to bring to the visit.

The short answer

A decentralized or hybrid clinical trial uses some remote or local steps, such as telehealth visits, local labs, home symptom reporting, or fewer trips to the study center. It may still require in-person care.

This page is educational. It is meant to help you prepare for care-team conversations, not diagnose a symptom, choose a treatment, or replace medical advice.

Why this matters

Less travel can make research more accessible, but the details matter. Safety monitoring, data privacy, local-provider coordination, scans, drug shipping, and costs should be clear before joining.

A practical way to prepare

  • Ask which visits are remote and which are in person.
  • Ask where labs, scans, biopsies, and urgent evaluations happen.
  • Ask who receives symptom reports and how quickly they respond.
  • Ask what costs, devices, internet needs, or travel remain your responsibility.

Questions to ask

  • What does this mean for my exact diagnosis, treatment, and current symptoms?
  • What should I do now, what can wait, and what should make me call sooner?
  • Is there a written plan, handout, or referral that would make this easier to follow?
  • Who should I contact after hours, and what information should I have ready?

What to keep in mind

Remote reporting is not emergency care. Ask exactly what to do for urgent symptoms and what local facility should be used if needed.

How this connects to the rest of care

Decentralized trials connect trial access, rural care, travel costs, safety reporting, and informed consent.

Common questions

Does this page tell me what to do medically?

No. It explains the topic in plain language so you can ask better questions. Your care team applies it to your diagnosis, treatment, test results, and symptoms.

What should I have ready when I ask about this?

Bring your treatment name, recent dates, current medicines, symptom timing, recent reports, and the exact question you want answered.

When should I contact the care team sooner?

Use the urgent plan your oncology team gave you, especially for symptoms that are new, severe, fast-changing, or specifically listed as warning signs for your treatment.
