The Resident files series contains personal medical information. As per regulations defined by the Health Insurance Portability and Accountability Act of 1996 (HIPAA), "individually identifiable health information of a person who has been deceased for more than 50 years is not protected health information under the Privacy Rule." To protect this information, files from this series will remain closed until 2050. Access to the records may be obtained prior to 2050 with the authorization from the decedent's executor, administrator, or other person who has authority under applicable law to act on behalf of the decedent or the decedent's estate.
All other records are open to researchers without restriction.
