Background. We assess the evidence that psychiatric patients are at in
creased risk of infection with HIV and discuss some of the clinical im
plications. Method. Surveys of HIV seroprevalence and risk behaviours
among psychiatric patients were obtained from a manual and computer se
arch (Medline and AIDSline).Results. Most studies report an increased
prevalence of HIV infection among psychiatric patients compared to the
general population. Risk behaviours, and obstacles to risk reduction,
are identified. Conclusions. There is a strong case for investigating
the seroprevalence of HIV in psychiatric settings in the UK. Issues r
elating to HIV and AIDS are likely to assume increasing importance in
general psychiatric practice.
