Few studies have designed and tested the use of continuous quality improvement approaches in community based substance use treatment settings. Little is known about the feasibility, costs, efficacy, and sustainment of such approaches in these settings.
METHODS/DESIGN: A group-randomized trial using a modified stepped wedge design is being used. In the first phase of the study, eight programs, stratified by modality (residential, outpatient) are being randomly assigned to the intervention or control condition. In the second phase, the initially assigned control programs are receiving the intervention to gain additional information about feasibility while sustainment is being studied among the programs initially assigned to the intervention.
By using this design in a pilot study, we help inform the field about the feasibility, costs, efficacy and sustainment of the intervention. Determining information at the pilot stage about costs and sustainment provides value for designing future studies and implementation strategies with the goal to reduce the time between intervention development and translation to real world practice settings.
很少有研究设计并测试在基于社区的物质使用治疗环境中使用持续质量改进方法。对于这些环境中此类方法的可行性、成本、疗效和持续性知之甚少。
方法/设计:正在进行一项采用改良阶梯楔形设计的群组随机试验。在研究的第一阶段,八个按模式(住院、门诊)分层的项目被随机分配到干预组或对照组。在第二阶段,最初分配的对照组项目正在接受干预,以获取关于可行性的更多信息,同时在最初分配到干预组的项目中研究持续性。
通过在试点研究中使用这种设计,我们有助于向该领域提供有关干预措施的可行性、成本、疗效和持续性的信息。在试点阶段确定有关成本和持续性的信息,对于设计未来的研究和实施策略具有价值,目标是缩短干预措施开发与转化为实际应用环境之间的时间。
