Design of a cluster-randomized, hybrid type 1 effectiveness-implementation trial of a care navigation intervention to increase substance use disorder treatment engagement: study protocol.
Article in Addiction science & clinical practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06729957 (Addressing Barriers to Care for Substance Use Disorder Trial), which is not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundPractical and motivational barriers can deter people from engaging in substance use disorder (SUD) treatment, even those who seek treatment. Care navigation is a psychosocial intervention that seeks to facilitate patients' timely access to care by identifying and intervening upon barriers. Few trials have tested the effectiveness of care navigation when embedding in real-world healthcare, and no trials have studied the process of implementing care navigation into clinical practice. This protocol describes a study that will evaluate whether care navigation can increase treatment engagement among patients seeking SUD treatment.
methodsThe Addressing Barriers to Care for Substance Use Disorder (ABC-SUD) study is a hybrid type I cluster-randomized effectiveness-implementation trial. It is conducted in a mental health access center of an integrated healthcare system in Washington state. Within this center, licensed mental health clinicians assess patient needs and use shared decision-making to establish SUD treatment plans for patients (usual care). This study tests whether an added care navigation intervention can improve patient engagement in SUD treatment. Care navigation begins after a treatment plan is made and provides up to 7 weeks of support focused on enhancing patient motivation to initiate and engage in treatment, problem-solving barriers (e.g., transportation logistics), and accommodating patient preferences (e.g., preferred language of care, cultural preferences). This trial uses a two period, two sequence crossover design. Clinicians are randomized to offer care navigation to patients during the first or second study period (i.e., clinicians are assigned to an initial study condition and switch conditions halfway through the trial). Care navigation is implemented with several strategies: leadership engagement, clinical workflow specifications, electronic health record (EHR) tools, training, performance improvement, and electronic learning collaborative. The primary outcome-obtained from EHRs and insurance claims-is engagement in SUD treatment, defined as ≥3 SUD treatment visits within 48 days of a treatment plan. This study uses standardized measures of implementation climate and outcomes to examine mechanisms with which the intervention strategies exert their impact on implementation and effectiveness outcomes. DISCUSSION: The ABC-SUD study will test whether care navigation improves SUD treatment engagement while concurrently generating information about its implementation in healthcare.
