title: The HIV-positive psychiatric patient and the duty to protect: ethical and legal issues.
abstract: A small, yet significant, percentage of HIV-positive patients have a concomitant psychiatric or neurological disorder associated with impaired judgment. Clinical problems such as psychoses, certain personality disorders, and dementias are associated with disinhibition of impulses and diminished capacity for self-monitoring. These deficits in reasoning and judgment may prevent the patient from comprehending the significance of their HIV status and the consequences of sexual behavior or needle sharing. There are indications that the Tarasoff duty-to-protect may apply to this situation.
  
  
  METHODS
  Available data about the prevalence of HIV risk behavior and HIV infection among psychiatric patients are reviewed. The applicability to these situations is described.
  
  
  RESULTS
  When an HIV patient engages in high risk sexual behavior with identifiable partners and refuses to notify them of their HIV status, physicians and mental health professionals may have a legal and ethical duty to warn.
  
  
  CONCLUSIONS
  A decision model for this clinical dilemma is presented. Clinical strategies for these patients may include ongoing supervision and monitoring as well as possible quarantine.
