While clinical trials have risks for the people who take part, each study also takes steps to protect patients. Doctors, nurses, social workers, and other health professional may be part of your treatment team. They will follow your progress closely. You may have more tests and doctor visits than you would if you were not taking part in a study. You will follow a treatment plan your doctor prescribes, and you may also have other responsibilities such as keeping a log or filling out forms about your health.
Some studies continue to check on patients even after their treatment is over.
In clinical trials, both research concerns and patient well-being are important. To help protect patients and produce sound results, research with people is carried out according to strict scientific and ethical principle. The study's investigator, usually a doctor, prepares an action plan for the study. Known as a protocol, this plan explains what will be done in the study and why. It outlines how many people will take part in the study, what medical tests they will receive and how often, and the treatment plan.
