Analysis of the use of HIV antibody testing in a Minnesota hospital.

We retrospectively studied the clinical use of human immunodeficiency virus (HIV) antibody serology at one 450-bed medical center and affiliated clinics from April 1985 through August 1986. No restrictions were placed on the use of HIV antibody serology during that time, although it was recommended that consent be obtained and risk-reduction information be provided. Testing was performed for 275 patients; results for 25 (9%) of these were positive. Nearly half (44%) of the patients had no recognized risk factor for HIV infection recorded in their charts. For an additional 44% of the patients, the test was medically indicated but consent and counseling were not documented. For only 10% of HIV antibody tests was there notation that consent was obtained and that risk-reduction information was provided. These results indicate that HIV antibody testing is often done without consent and that opportunities to provide risk-reduction counseling are being missed.
