Blended Treatment for Alcohol Use Disorder (BLEND-A) is a pragmatic, cluster randomized controlled trial to assess the clinical effectiveness and cost-effectiveness of implementing a blended treatment format that aims to reduce problematic alcohol use. Blended treatment is a treatment format where treatment as usual is offered as a combination of online and face-to-face sessions, integrated into one treatment protocol. The BLEND-A study will evaluate and implement a blended treatment program in routine alcohol addiction treatment. The trial is led by Unit of Clinical Alcohol Research, University of Southern Denmark (UCAR) in collaboration with partners at the Centre for Telepsychiatry in the Region of Southern Denmark (CTP), and Sundhed.dk.
Background: A major challenge to psychological treatment for Alcohol Use Disorder (AUD) is patient non-compliance. A promising new treatment approach that is hypothesized to increase treatment compliance is blended treatment, consisting of face-to-face contact with a therapist combined with modules delivered over the Internet within the same protocol. While this treatment concept has been developed and proven effective for a variety of mental disorders, it has not yet been examined for AUD.
Aims: The study described in this protocol aims to examine and evaluate patient compliance with blended AUD treatment as well as the clinical and cost effectiveness of such treatment compared to face-to-face treatment only.
Methods: The study design is a pragmatic, stepped-wedge cluster randomized controlled trial. The included outpatient institutions (planned number of patients: n=1800) will be randomized in clusters to implement either blended AUD treatment or face-to-face treatment only, i.e. treatment as usual (TAU). Both treatment approaches consist of motivational interviewing and cognitive behavioral therapy. Data on socio-demographics, alcohol consumption, addiction severity, treatment retention, treatment duration and intensity, and type of conclusion of treatment (dropout vs. compliance), will be retrieved from the National Register of Alcohol Treatment (NAB). In addition, all patients will be assessed for alcohol consumption, consequences of drinking and quality of life at treatment entry and six months after treatment conclusion. Data will be analyzed with an Intention-to-treat approach by means of generalized mixed models with random effect for cluster and fixed effect for each step. Also, analyses evaluating cost-effectiveness will be conducted.
Discussion: Blended treatment may increase treatment compliance and thus improve treatment outcomes due to increased flexibility of the treatment course. Since this study is conducted within an implementation framework it can easily be scaled up, and blended treatment has the potential to become an alternative offer in the majority ofmany outpatient clinics nationwide.

| Measure | Description | Time Frame |
|---|---|---|
| Compliance and premature dropout in alcohol treatment | BLEND-A (outpatient treatment as usual offered as a combination between face-to face and internet-based sessions) leads to a change in compliance in treatment during one year following initiation of treatment, compared to TAU (usual treatment delivered as face-to-face outpatient treatment only ), and measured as a change in premature dropout of treatment in the National Register of alcohol treatment (NAB). | One year after enrolled in the study |
| Effectiveness of alcohol treatment | The effectiveness of BLEND-A compared to TAU, measured by alcohol intake 6 months after treatment start. The alcohol intake is measured by self-reported alcohol intake. | 6 months after enrolled in the study |
| Measure | Description | Time Frame |
|---|---|---|
| Differences in Quality of Life according to the intervention | BLEND-A leads to a change in quality of life (measured by means of Patient Reported Outcomes (PRO)) among patients, compared to face-to-face outpatient treatment as usual, measured 6 months after treatment start. | 6 months after enrolled in the study |
| Measure | Description | Time Frame |

| Qualitative interviews | The perspectives for further refinement of BLEND-A will be assessed by qualitative interviews with patients and therapists receiving or delivering the intervention. | Through study completion, an average of 1 year |
