Health risks and opportunities for harm reduction among injection-drug-using clients of Saskatoon's needle exchange program.

Information about injection drug users' lifestyles is necessary to develop effective harm reduction strategies. One way to gather this information is through needle exchange programs. In 1998, a convenience sample of 100 clients of Saskatoon's needle exchange service was interviewed about their injection and sexual practices. Ritalin and morphine were the most commonly injected drugs. Over half the participants (53%) reported having shared needles, usually with friends, relatives, and partners. Slightly more (62%) had shared injection equipment. Most participants had multiple sexual partners, especially the women, half of whom were sex trade workers. Condom use was higher with casual partners than with regular partners. While awareness about HIV transmission was high, most participants considered their risk of infection to be below average. These findings are discussed in light of the insights they provide regarding both health risks and opportunities for harm reduction in the study population.

Blood collections by community blood centers, 1988 through 1992.

BACKGROUND: The provision of a safe and sufficient supply of blood is critical to patient care. STUDY DESIGN AND METHODS: A survey was conducted of the blood collection activity of the 189 community blood centers operating in the United States from 1988 through 1992. Data were analyzed by source of the donation (allogeneic or autologous), by center's collection volume, and by geographic region. Total collection figures were compared to historical blood collection activity since 1970. RESULTS: A total of 12.31 million units of blood were collected in 1992, an increase of 2.6 percent over the total number of units collected in 1988. For the 5-year period (1988-1992), total collections increased at a compound annual growth rate of 0.6 percent. The collection of allogeneic blood units declined by 0.2 percent annually, while that of autologous units increased by 23.2 percent annually. Autologous blood units accounted for 5.7 percent of total collections in 1992. Nationally, 48 units were collected per 1000 people in 1992, although substantial geographic variation (range, 38-64 units/1000) was observed across nine US census regions. CONCLUSION: The data from this study provide evidence that the total supply of blood grew more slowly from 1988 through 1992 than in the years before 1988.
