Many methadone programs in the United States have waiting lists for care.
To examine specific predictors of treatment entry among individuals on a waiting list for methadone maintenance.
Heroin users placed on a waiting list for methadone treatment (n = 120) were administered a urine screen for drug use and assessed with a battery of measures at study entry and at 4 month follow-up as part of a larger clinical trial. Logistic regression was used to examine hypothesized predictors of treatment entry. Outcomes for those failing to enter treatment were also examined.
Only 25 individuals (20.8%) entered treatment within four months of being placed on a waiting list. Intravenous drug users were more likely to enter treatment (p <.05) whereas cocaine users were less likely to do so (p <.01). Motivation did not predict treatment entry, and cocaine use did not moderate this relationship. There were some improvements in heroin use among those who did not enter treatment.
Additional research is needed on the relationship between motivation and treatment entry. Programs may need to make special efforts to facilitate entry for treatment-seeking heroin users who also use cocaine.
These findings have implications for improving access to methadone treatment.
美国许多美沙酮项目都有等待接受治疗的名单。
研究美沙酮维持治疗等待名单上的个体进入治疗的具体预测因素。
作为一项更大规模临床试验的一部分，将被安置在美沙酮治疗等待名单上的海洛因使用者（n=120）接受尿液药物检测，并在研究开始时和 4 个月随访时进行一系列评估。使用逻辑回归检验假设的治疗进入预测因素。还检查了未进入治疗的人的结果。
只有 25 人（20.8%）在等待名单上的四个月内进入治疗。静脉注射药物使用者更有可能进入治疗（p<.05），而可卡因使用者则不太可能进入治疗（p<.01）。动机并不能预测治疗进入，可卡因使用并不能调节这种关系。未进入治疗的人的海洛因使用有所改善。
需要进一步研究动机与治疗进入之间的关系。对于寻求治疗的同时也使用可卡因的海洛因使用者，项目可能需要特别努力促进他们进入治疗。
这些发现对改善美沙酮治疗的可及性具有影响。
