Investigators with the Yale University School of Organization and Management and the City of New Haven, Department of Health, worked to expand and evaluate a model needle exchange program in New Haven.
Needle exchange programs seek to reduce the spread of HIV via infected needles by providing intravenous (IV) drug users with clean syringes. In 1990, New Haven's local government mandated a demonstration needle exchange program along with an independent program evaluation.
The Robert Wood Johnson Foundation (RWJF) provided two grants to the Yale University School of Organization and Management totaling $208,132 from January 1992 to June 1992. RWJF provided a grant of $515,544 from June 1992 to May 1999 to the City of New Haven, Department of Health.
By 1987, over three-quarters of all AIDS cases in New Haven, Conn., resulted from IV drug use, either directly (through sexual contact with a user or through a shared syringe) or indirectly (from an infected mother to her fetus). In a 1987 survey, IV drug users in New Haven revealed that fear of arrest, scarcity of sterile needles, and the high cost of syringes significantly contributed to needle sharing.
To reduce the transmission of HIV through the sharing of these needles, New Haven's local government mandated a demonstration needle exchange program with an independent program evaluation. The needle exchange program, started in November 1990, employed a mobile van to visit several sites during its four-day-a-week operation.
Staff members exchanged sterile needles for used ones and distributed bleach, water bottles, condoms, and HIV literature. In addition, they gave clients drug treatment information and provided them with referral assistance.
These grants from RWJF supported the expansion of New Haven's model needle exchange program and its evaluation. The evaluation (ID#s 019227, 020049) provided an opportunity to demonstrate that needle exchange could be an effective HIV-infection reduction strategy without promoting drug use or increasing the number of IV drug users in the community.
The researchers believed that the needle exchange program would not increase the number of needles in circulation because users would be required to return a distributed needle at the same time they received a new one.
Instead, by providing users with an opportunity to exchange their used needles for clean ones, the researchers' goal was to reduce the amount of time each needle remained in circulation, reducing the likelihood that it would become contaminated with HIV. That, in turn, would reduce the number of contaminated needles in circulation.
The researchers developed a syringe tracking and testing system to assist in the evaluation of the program. They monitored the amount of time needles remained in circulation before being turned in, and they tested the needles for the presence of HIV proviral DNA. The evaluation also monitored client enrollment, demographics, and the number of participants entering drug treatment programs.
The evaluation used information from self-reported questionnaires, completed by each client at the time of enrollment and at follow-up. Along with client demographics, the questionnaire collected behavioral information such as how long a client had been injecting drugs, the frequency of drug injection, the frequency of syringe cleaning and sharing, the risks taken in sexual practice, and the use of condoms.
Concurrently with the evaluation, RWJF provided a grant to expand the program (ID# 019924). The expansion was meant to ensure that the evaluation would be examining a robust, fully functioning project.
The principal objectives were to: Increase the number of program staff to include outreach workers, a drug treatment coordinator, and a field manager. Purchase and outfit a second mobile van. Increase the number of sites covered and expand the program's hours of operation. Enhance health education, referral, and client follow-up.
The first year of the needle exchange program evaluation was completed by Yale University on a pro bono basis. Investigators also received a three-year, $1-million grant from the National Institute on Drug Abuse (NIDA) to fund program activities.
The investigators published more than 30 articles in professional journals, including the New England Journal of Medicine and the Journal of the American Medical Association.
Project staff made presentations at numerous national and international conferences, including several international AIDS conferences, the American Public Health Association annual meeting, and meetings at the National Academy of Sciences and the Centers for Disease Control and Prevention.
The investigators were also interviewed on several local and national television stations, and appeared on the NBC "Today" show and the Discovery Channel's "Cronkite Report." The syringe tracking and testing research has been reported on in US News and World Report, the New York Times, and the Washington Post.
The General Accounting Office documented results of the program in a report to the House select committee on narcotics abuse and control. Within the research community, the evaluation won two prestigious awards the Franz Edelman Award for Management Science Achievement and the Frederick Lanchester Prize.
The director of the needle exchange program made presentations to several municipalities considering establishing their own needle exchange programs. In addition, the New Haven AIDS Division operated a Web site concerning the needle exchange program for almost a year. Program staff also produced a television program that aired on BET, Lifetime, E!, and MTV for 13 weeks. (See the Bibliography for a complete listing of publications and presentations.)
The needle exchange program continues to operate. The loss of grant funds and city and state budget changes have led to the elimination of several staff positions. Staff members hope to develop a syringe disposal system and a home delivery program, and to expand the hours of operation at least one night a week into the early morning hours.
As a result of the research documenting evidence of the efficacy of the New Haven needle exchange program, other states have become interested in needle exchange programs. New needle exchange programs have begun in New York City, California, and Massachusetts.
Connecticut has expanded the program to include Bridgeport and Hartford.
Needle exchange programs continued to spread across the country. In 2007, New Jersey became the final state in the United States to adopt a needle exchange program.
