The aim of this study was to evaluate the efficacy of a theory-based intervention to increase the use of a new syringe for each injection among injection drug users (IDUs). Users of two needle exchange programs (NEPs) were involved. At both sites, participants were assigned at random to either the experimental or the control group. Once a week for four weeks, users reported to the NEPs where they logged onto a computer and received an audiovisual message. A total of 260 IDUs were recruited. At baseline, 52.3% of participants reported that they had not always used new syringes in the previous week. The results indicate that it is possible for IDUs to adopt safer injection practices. One month after the intervention began, participants in the experimental group were using fewer dirty syringes compared to the control group (RR: 0.47 CI(95%) 0.28-0.79; P = .004). This short-term effect was no longer present 3 months later.
本研究旨在评估一项基于理论的干预措施的效果，该干预措施旨在增加注射吸毒者（IDU）每次注射时使用新注射器的频率。本研究涉及了两个针具交换项目（NEP）的使用者。在两个地点，参与者被随机分配到实验组或对照组。在四周内，每周一次，使用者到 NEP 报到，在那里他们登录到计算机并接收视听信息。总共招募了 260 名 IDU。在基线时，52.3%的参与者报告说，他们在过去一周内并非总是使用新注射器。结果表明，IDU 有可能采用更安全的注射方式。在干预开始一个月后，实验组参与者与对照组相比，使用的脏注射器数量更少（RR：0.47 CI（95%）0.28-0.79；P=0.004）。3 个月后，这种短期效果不再存在。
