The decision to do so will not impact any other aspect of a persons medical care. Unless a participant refuses there is ongoing follow up activity until a trial is closed out. This is simply for the purpose of collecting research information. A person may refuse to particpate in the follow up phase after dropping out. Again, there is no aspect of a persons medical care that will be effected if a person refuses to partipate in follow up activities.
Painstaking care is given to ethical issues at all ARAC sites.
Every aspect of the trial must be fully explained to a potential participant prior to enrollment. Enrollment is not completed and participation is denied unless a potential particpant signs the required consent forms. As sometimes happens a trial may require changes. If changes occur a particpant is required to agree to the changes and they must sign another consent which details the trial and the changes made. Should a participant not agree to the changes their particpation will end.
