A signed consent form does not relieve a doctor of his or her responsibility to provide an acceptable standard of care. The success of your claim for damages rests upon proving that you were injured as a result of the doctor’s negligence, so you should not be deterred from pursuing a case against them if you consented to a treatment that they suggested. They are still liable for any subsequent errors in judgment and/or mistakes caused by carelessness if you are injured as a result.
