Evaluating Improvement Strategies in Addiction Treatment (NIATx 200)

Randomized Control Trial (RCT) Evaluating Improvement Strategies in Addiction Treatment

Addiction treatment is often characterized by long delays between first contact and treatment as well as high no-show and drop out rates leading to unused capacity in apparently full agencies. Patients do not get needed care and agency financial stability is threatened. The Network for Improvement of Addiction Treatment (NIATx) began as a high-intensity improvement collaborative of 39 addiction treatment agencies distributed across 25 states. NIATx substantially improved time to treatment and continuation in treatment by making improvements to organizational processes (such as first contact, intake and assessment, engagement, level of care transitions, paperwork, social support, outreach, and scheduling) in preliminary studies. While the results are very encouraging, they have, by intent, been obtained from a select group of agencies using a high-cost combination of services. A more practical diffusion model is needed to spread process improvements across the spectrum of treatment agencies. This study is a cluster-randomized trial to test the effectiveness and cost of less expensive combinations of the services that make up the NIATx collaborative (interest circles, coach calls, coach visits and learning sessions).

Study Overview

• Status: Completed
• Conditions: Addiction
• Intervention / Treatment: Other: Interest Circle Calls; Other: Website; Other: Coaching; Other: Learning Session

Detailed Description

This cluster-RCT randomly assign 201 treatment agencies in 5 states to four experimental arms. The agencies were randomized to an intervention for 18 months with a 9 month sustainability period. The study aimed to: 1) Determine whether a state-based strategy can (with NIATx support) can lead mainstream treatment agencies to implement and sustain process changes that improve the study's primary outcomes: time to treatment, annual clinic admissions, and continuation in treatment; and 2) Evaluate the effectiveness and cost of the services making up NIATx. This study aims to create a practical model for improving efficiency and effectiveness of addiction treatment.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Interest Circle Call + Website; Interest Circles are monthly teleconferences where agency change leaders discuss change-related issues and progress. Circles address how to improve timeliness, continuation, admissions, dropouts and transitions. They also address specialty topics (e.g., programs for women, adolescents). Participants discuss successes, failures, and challenges, and get advice and assignments for their improvement plans. Meeting summaries appear on the Web site. Interest Circles are inexpensive, but are they are sufficient? Should Interest Circles prove effective, they would provide a low-cost, convenient diffusion approach.

Should Interest Circles prove effective, they would provide a low-cost, convenient diffusion approach; Other: Website; The NIATx Web site features resources central to improvement. The site includes: 1) a catalog of change ideas and case studies; 2) a toolbox providing just-in-time training on topics such as conducting a walk-through and key innovations; 3) on-line tools to assess organizational (or project) readiness for and ability to sustain change; 4) electronic communication services to ask questions of experts, and participate in peer discussion groups; 5) links to relevant process improvement Web sites; and 6) a secure portion for treatment agencies to report and track progress. Hence, our control group will have access to the entire website.
Experimental: Coaching + Website; Coaching assigns an expert in process improvement to work with an agency to make, sustain, and spread process improvement efforts. Consultations focus on executive directors, change leaders and improvement teams. Coaches help agencies address key issues, but also broker relationships with other agencies, offer process improvement training, and promote the innovations to make and how to make them. Coaching takes place during site visits, monthly phone conferences, and via email.	Other: Website; The NIATx Web site features resources central to improvement.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Average Waiting Time From First Contact to Treatment	The average length of time in days it takes from when a patient first calls for help to the time a patient was able to meet a clinician. In this quality improvement study, changes in this measure over time are reported. Estimates of improvement show the average days of improvement per month based on a best linear unbiased predictor estimate for each site. Note: this study has three primary outcomes. The number of participants analyzed varies for each outcome. The (higher) number of clinics shown in the flow diagram results because clinics may have been analyzed on a subset of the three primary outcomes (e.g., analyzed for waiting time and continuation, but not for annual number of new patients). To be considered "analyzed" in the flow diagram, a clinic must have been included in at least one primary outcomes analysis.	Baseline and 15 months
Change in Annual Number of Patient Admissions	We aimed to increase clinics' treatment capacity in this quality improvement study. Capacity was measured by counting clinics' annual number of patient admissions. We monitored changes in admission counts, per clinic, in a pre-post analysis. Changes in the natural logarithm of annual admissions are presented, which approximates the average percentage change (year-to-year) in the number of new patient admissions per clinic. Note: this study has three primary outcomes. The number of participants analyzed varies for each outcome. The (higher) number of clinics shown in the flow diagram results because clinics may have been analyzed on a subset of the three primary outcomes (e.g., analyzed for waiting time and continuation, but not for annual number of new patients). To be considered "analyzed" in the flow diagram, a clinic must have been included in at least one primary outcomes analysis.	48 months (2 year baseline period and 2 year post-intervention period)
Change in Average Continuation Rate Through the Fourth Treatment Session	This outcome represents change in the rate at which a clinic's patients continue in treatment. Continuation rate is defined as the percentage of patients that make at least 4 visits to the clinic, on different days, before being discharged. Estimates of improvement show the average percentage points of improvement per month based on a best linear unbiased predictor estimate for each site. Note: this study has three primary outcomes. The number of participants analyzed varies for each outcome. The (higher) number of clinics shown in the flow diagram results because clinics may have been analyzed on a subset of the three primary outcomes (e.g., analyzed for waiting time and continuation, but not for annual number of new patients). To be considered "analyzed" in the flow diagram, a clinic must have been included in at least one primary outcomes analysis.	Baseline and 21 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cost of Group	The goal of the economic analysis was to estimate costs of each group for governmental authorities who might organize improvement collaboratives. We collected the cost of personnel (state employees, NIATx employees, coaches and consultants), data management, buildings and facilities, lodging, travel, telephone calls and miscellaneous costs. Costs were categorized as group specific (such as hotel costs for the learning sessions group) or non-group-specific, which included state-incurred costs for outreach, data management and infrastructure, encouraging participation and administration. Cost data were collected three times during the study period and aggregated to create a total cost estimate. Figures reported below represent costs at the arm/group level (costs were not assessed at the organizational level). Measure type is "Number."	Baseline and 18 months
