Patients are asked to sign (electronic agreement) a consent to participate in this confidential study when they initially log-on to the study website. Patients are assigned a unique identification number when they log into the internet for the first time to complete the study survey. By using this assigned number, health information will be protected for each individual. Patient names will be used only for purposes of check distribution and participation in following studies if the patient consents. If a patient drops out of the study, TNS Healthcare will contact the patient to find out the reason. The treating physician does not know who elected to participate in the study.
