Abstract

Background: Although contingency management has shown some efficacy in substance use disorder treatment, digital contingency management (DCM) needs more evidence supporting its value in treating substance misuse.

Objective: This study aimed to evaluate the effectiveness of DCM in treating substance use disorder by examining 2 key outcome variables-abstinence and appointment attendance.

Methods: A 12-month quasi-experimental design was conducted by enrolling patients into 2 groups using an alternating assignment process: one group receiving treatment-as-usual plus DCM and the other receiving treatment as usual with no contingency management. Propensity score matching was conducted to match groups on covariates. After matching, t tests were conducted to examine the difference between groups on urine abstinence and appointment attendance rates.

Results: Two cohorts of propensity-matched patients (66 interventions and 59 controls) were analyzed. Abstinence was significantly higher in the DCM group (mean 0.92, 95% CI 0.88-0.96) than in the treatment-as-usual group (mean 0.85, 95% CI 0.79-0.90; P<.01). Appointment attendance also demonstrated significant differences between the groups, with the DCM group achieving a mean rate of 0.69 (95% CI 0.65-0.74) compared with 0.50 (95% CI 0.45-0.55) in the treatment-as-usual group (P<.001). This notable increase highlights the role of DCM in fostering engagement with care, an essential factor for successful treatment outcomes.

Conclusions: The results suggest that DCM can be an effective treatment modality for substance use disorder.

物质使用障碍治疗的数字应急管理：12个月的准实验设计。

背景：虽然应急管理在药物使用障碍治疗中显示出一定的疗效，但数字应急管理（DCM）在药物滥用治疗中的价值还需要更多的证据来支持。目的：本研究旨在通过检查戒断和预约出勤率两个关键结果变量来评估DCM治疗物质使用障碍的有效性。方法：采用12个月的准实验设计，采用交替分配过程将患者分为两组：一组接受常规治疗+ DCM，另一组接受常规治疗，不进行应急管理。采用倾向评分匹配方法对组间的协变量进行匹配。配对后，进行t检验，检验各组之间尿禁和预约出勤率的差异。结果：分析了两组倾向匹配的患者（66名干预组和59名对照组）。DCM组戒断率（平均0.92,95% CI 0.88-0.96）明显高于常规治疗组（平均0.85,95% CI 0.79-0.90）。结论：DCM可作为药物使用障碍的有效治疗方式。
