Costs, time and travel

Before you agree to a study, it helps to know what it will cost you in money, in time and in miles. Teams expect these questions, so ask them early.

Who pays for the study itself

The study treatment and the tests the study requires are normally paid for by the sponsor. Your usual care, the care you would receive anyway, may still be billed to you or your insurer in the normal way. The consent form should say which is which; if it is unclear, ask the coordinator to go through it with you.

Payments and reimbursement

Some studies pay volunteers for their time, often a set amount per visit. Others reimburse travel, parking or meals, and some offer nothing. All of these are acceptable, as long as the form says plainly what applies. Payments are usually spread across the study rather than given at the end, so that leaving early does not cost you what you have already earned.

How much time it takes

Screening. Often the longest visit, sometimes half a day.
Regular visits. From under an hour to several hours, depending on the tests.
Between visits. Diaries, questionnaires or phone calls at home.
Follow-up. Calls or visits after treatment ends, sometimes for months.

Getting there

Ask how far the site is and whether visits can be scheduled around work or school. Some studies arrange transport or pay for a taxi, and many now do part of the work by video or at your home. If travel would stop you from taking part, say so: there may be a site closer to you running the same study.
