UCLA's neuropsychiatric hospital has banned all cellphones and laptop computers after a patient posted group photos of other patients on a social networking website. The decision was part of "UCLA Health System's ongoing efforts to enhance patient privacy and confidentiality in compliance with California's patient rights law," according to a statement from the hospital. In response to UCLA's move, officials at the California Hospital Assn. said they are hearing more and more hospitals express concern over how to deal with cellphone cameras.
