According to their interpretations of HIPAA, hospitals will not reveal information over the phone to relatives of admitted patients. This has in some instances impeded the location of missing persons. After the Asiana Airlines Flight 214 San Francisco crash, some hospitals were reluctant to disclose the identities of passengers that they were treating, making it difficult for Asiana and the relatives to locate them. In one instance, a man in Washington state was unable to obtain information about his injured mother.
