Serological testing of waste bloods revealed that 25 (7%) of 350 acutely
ill psychiatric inpatients had HIV infection. Eight of the 10 HIV-positive
patients whose serological status was not recorded on admission were
discharged with their status still unrecorded and presumably undetected.
Thirty-nine (51%) of the 77 inpatients with HIV- related risk behaviors
identified on admission were discharged with no record of their having been
serologically tested before or during hospitalization.
