 2. Loss of confidentiality. Just as with other medical information from routine medical care, all study related information will be kept as confidential as possible. Study information will be kept in locked files and in databases with password protected access. Participant names and any other identifying information will not be released from the clinic and it will not be used in any published reports about this study. There is a need to share protected health information with the study staff at the clinic and because of this, absolute confidentiality cannot be guaranteed.
