背景资料：针对注射吸毒者的创新性保健方案，如监督注射设施，往往是在对注射吸毒者使用服务的意愿进行评估之后才实施的。这些调查的有效性尚未得到充分评价。我们试图确定加拿大SIF开放前收集的意愿措施是否准确预测了该计划的后续使用。方法：数据来自一个前瞻性队列的注射吸毒者。本研究的样本量为640名注射吸毒者。使用多变量logistic回归，评估是否有报告愿意使用该程序的历史（如果可用）与随后的使用相关。在子分析中，仅限于有自愿报告史的个体，我们使用多变量纵向分析来确定与不参加SIF相关的因素。结果如下：在442名注射吸毒者中，72%的人报告最初愿意使用SIF后来参加了该计划，先前愿意使用SIF显着预测以后的出勤率（调整后的比值比= 1.67）。在子分析中，仅限于那些有使用SIF的意愿报告的历史，不使用该程序的预测不经常光顾的SIF所在的社区。结论：我们的研究结果表明，报告的意愿措施，从注射吸毒者收集有关潜在的SIF计划参与开放前独立预测以后的出勤率，即使变量，可能的决定因素的意愿进行了调整。这些数据表明，意愿措施是合理有效的工具，规划提供医疗服务的注射吸毒人群。
Background: Innovative health programs for injection drug users (IDUs), such as supervised injecting facilities (SIFs), are often preceded by evaluations of IDUs' willingness to use the service. The validity of these surveys has not been fully evaluated. We sought to determine whether measures of willingness collected prior to the opening of a Canadian SIF accurately predicted subsequent use of the program. Methods: Data were derived from a prospective cohort of IDUs. The sample size for this study was 640 IDUs. Using multivariate logistic regression, it was assessed if a history of reporting willingness to use the program, were it available, was associated with subsequent use. In sub-analysis restricted to individuals who had a history of reported willingness, we used multivariate longitudinal analysis to identify factors associated with not attending the SIF. Results: Among 442 IDUs, 72% of those who reported initial willingness to use a SIF later attended the program, and a prior willingness to use a SIF significantly predicted later attendance (adjusted odds ratio = 1.67). In sub-analyses restricted to those who had a history of reporting willingness to use the SIF, not using the program was predicted by not frequenting the neighborhood where the SIF was located. Conclusion: Our findings indicate that reported willingness measures collected from IDUs regarding potential SIF program participation prior to its opening independently predicted later attendance even when variables that were likely determinants of willingness were adjusted for. These data suggest that willingness measures are reasonably valid tools for planning the delivery of health services among IDU populations.
