 This entry principally deals with the professional work of physicians, nurses and other trained and licensed medical caregivers, along with hospitals, insurance companies and researchers. Privacy in relation to wellness and well-being are beyond the scope of this entry, except to the considerable extent that it prompts encounters with medical professionals and organizations.  Wellness encounters with spiritual, fitness or non-medical beauty professionals are not discussed. Finally, while the privacy of patients and biomedical research subjects is the focus of this entry, philosophical questions concerning health professionals’ own privacy-related interests implicated in medical practice are recognized.
