Partner notification for control of HIV: results after 2 years of a statewide program in Utah.

OBJECTIVES

We sought to evaluate the utility of partner notification for control of human immunodeficiency virus (HIV) infection and to identify subgroups in which it may be most effective.

METHODS

All persons reported to be HIV-positive during a 2-year period were interviewed. Outcome measures included proportion of index patients cooperating; number of partners named, located, counseled, and tested; number of persons newly testing positive; and costs.

RESULTS

Of 308 index patients, 244 (79%) cooperated. They named 890 partners; 499 (70%) of in-state partners were located. Of these, 154 (34%) had previously tested HIV-positive. Of 279 partners tested for the first time, 39 (14%) were HIV-positive. Injecting drug users were significantly more likely to cooperate than persons in other risk groups (93% vs 76%) and named more partners (median 4 vs 1). Women and persons choosing confidential testing were more likely to cooperate and named more partners. The estimated cost of the program was $62,500 per year.

CONCLUSIONS

Partner notification identified a group with a high seroprevalence of HIV. It was not successful among populations that may be difficult to reach with other interventions.
