Scientific evidence is at the heart of CHESS.

In clinical trials and in provider implementations, individuals using the Connections App had more treatment services, completed IOP treatment 20% more often, and were 30% less likely to drop-out early from OP treatment.

A Medicaid MCO did a retrospective claims analysis comparing members who used Connection App and found these members were 2.9x less likely to incur a readmission to a residential/inpatient level of care than members – the resulting cost of care savings averaged $278 per member per month.

Using the app for longer than 30 days correlates to a 40% reduction in risk factor measures (difficulty sleeping, relationship troubles, struggle with cravings, etc.) measured through weekly patient assessments.

Our platform was co-founded by University of Wisconsin professor David H. Gustafson, PhD, who developed the “ACHESS” smartphone app and validated its effectiveness in multiple studies. We have since added a partnership with Yale School of Medicine professor Kathleen M. Carroll, PhD, with the goal of commercializing her innovative, clinically-validated online programs for sustained recovery.

The body of evidence supporting the efficacy of the CHESS Health platform also includes results and case studies from customers who have implemented our solutions.

Using Smartphones to Improve Treatment Retention Among Impoverished Substance-Using Appalachian Women: A Naturalistic Study

Longer retention in treatment is associated with positive outcomes. For women, who suffer worse drug-related problems than men, social technologies, which are more readily adopted by women, may offer promise. This naturalistic study examined whether a smartphone-based relapse-prevention system, A-CHESS (Addiction-Comprehensive Health Enhancement Support System), could improve retention for women with substance use disorders in an impoverished rural setting.

Youth in Intensive Outpatient Treatment at New Directions, Inc.

New Directions, Inc., contracted with the Begun Center for Violence Prevention, Research and Education (Begun Center) in the Jack, Joseph and Morton Mandel School of Applied Social Sciences at Case Western Reserve University (CWRU) to evaluate the utility and impact of the Addiction Comprehensive Health Enhancement Support System (ACHESS) on youth undergoing intensive outpatient (IOP) treatment. ACHESS is a combined client-facing mobile phone application (“app”) and web-based clinician dashboard used to support and monitor clients seeking addiction treatment.

An E-Health Solution For People With Alcohol Problems

Self-management of chronic diseases has been a research focus for years. Information and communication technologies (ICTs) have played a significant role in aiding patients and their families with that management task. The recent dramatic increase in smartphone capabilities has expanded the potential of these technologies by facilitating the integration of features specific to cell phones with advanced capabilities that extend the reach of what type of information can be assessed and which services can be provided. A recent review of the literature covering the use of ICTs in managing chronic diseases, including addiction, has examined the effectiveness of ICTs, with an emphasis on technologies tested in randomized controlled trials. One example of an addiction-relapse prevention system currently being tested is the Alcohol Comprehensive Health Enhancement Support System (A-CHESS) Program.
