The use of illicit drugs plays a critical role in the spread of HIV, with a
pproximately one-half of all new HIV infections in the United States attrib
uted to this mode of transmission. There is a renewed emphasis on developin
g special HIV counseling and testing (C&T) programs for drug users. We cond
ucted a qualitative study of C&T providers to identify client-centered and
structural barriers to providing HIV C&T to high-risk drug users. Interview
s focused on obtaining a detailed description of the services; successful a
nd problematic forms of organization, financing, and service delivery; clie
nt access and barriers to C&T services; recommendations for increasing C&T
accessibility and utilization by drug users; and linkages between C&T and o
ther HIV-prevention and intervention services. The results of our interview
s illustrate that it is tremendously complex and challenging work to provid
e C&T to populations with multiple and immediate needs within a context of
layered constraints on individual behavior, provider resources, and service
delivery. Providers clearly understand client-centered and structural barr
iers and have demonstrated a commitment to overcoming the barriers related
to AIDS stigma, confidentiality, material needs, and fear when delivering H
IV C&T services.
