 AB    We have developed a decision-support tool, the AIDS Intervention
       Decision-Support System (AIDS2), to assist in the task of matching
       patients to therapy-related research protocols. The purposes of AIDS2
       are to determine the initial eligibility status of HIV-infected patients
       for therapy-related research protocols, and to suggest additional
       data-gathering activities that will decrease uncertainty related to the
       eligibility status. AIDS2 operates in either a patient-driven or
       protocol-driven mode. We represent the system knowledge in three
       combined levels: a classification level, where deterministic knowledge
       is represented; a belief-network level, where probabilistic knowledge is
       represented; and a control level, where knowledge about the system's
       operation is stored. To determine whether the design specifications were
       met, we presented a series of 10 clinical cases based on actual patients
       to the system. AIDS2 provided meaningful advice in all cases.
