Answer: This might not be right but this is the way I see it
Explanation: As doctors one of our number one priorities is patient confidentiality, however another priority is the safety of our patient. Lets say that a patient is admitted in the hospital and it's pretty obvious the patient is struggling with substance abuse, what do you do? Do you protect your patients confidentiality or do you disclose your patients situation in order to aid them with some help from other colleges who specialize in the treatment of substance abuse? Think of it like this, A school shrink is obliged to keep the student's problems confidential unless in the event that the student is being hurt or is thinking about hurting themselves or others. At that moment the students safety becomes more important, and the appropriate facility is contacted like CPS or a mental hospital.
