All these elements are required because they are part of the process the research team needs to follow in order to get your agreement (consent) to participate in their project. This will be documented by the research team. You should be given a sufficient amount of time to decide whether or not he/she wishes to participate.
Refusal to enroll in a research project must not influence or jeopardize the relationship with your physician, nor the services or the treatment you are receiving. Even after accepting to participate (written or oral consent) in project you can reverse your decision at any time without fear of repercussions on the quality of future medical care or your job depending on your situation.
By participating in a research project, you do not waive any of your rights.
For more information about your participation in a research project, you can consult this brochure from the Panel on Research Ethics.
