背景：针头和注射器计划（NSP）的覆盖率通常在个人层面计算。该方法将无菌针头和注射器的获取与注射频率联系起来，导致使用无菌注射器的注射事件的百分比。以往使用该方法的研究大多受限于其横断面设计，需要对覆盖范围进行纵向探索。方法：我们使用了来自澳大利亚墨尔本正在进行的注射吸毒者队列的518名参与者的数据。我们在每次访谈前两周计算了个人层面的注射器覆盖率，然后将结果分为“充分”（>=至少有一个报告的无菌注射器覆盖的注射事件的100%）或“不足”(
Background: Needle and syringe program (NSP) coverage is often calculated at the individual level. This method relates sterile needle and syringe acquisition to injecting frequency, resulting in a percentage of injecting episodes that utilise a sterile syringe. Most previous research using this method was restricted by their cross-sectional design, calling for longitudinal exploration of coverage.Methods: We used the data of 518 participants from an ongoing cohort of people who inject drugs in Melbourne, Australia. We calculated individual-level syringe coverage for the two weeks prior to each interview, then dichotomised the outcome as either "sufficient" (>= 100% of injecting episodes covered by at least one reported sterile syringe) or "insufficient" (
