Success rates of smoking cessation therapies to patients with mental illness by video consultants or by treatment in the community: A Randomized Controlled Trial.

Introduction
Smoking is probably the one single factor with the highest impact on reducing the life expectancies of patients with mental illness. This is due to high injurious to health and due to high rates of smoking among patients with mental illness. In Denmark, 38.8% of patients with persistent mental health problem are smoking. Patients may have problem in participating in ordinary smoking cession programs offered in the community, but they are concerned about the impact of tobacco use on their health and finances and are motivated to stop smoking.
Videoconferencing addressing smoking cessation might be an alternative to ordinary consultation at the clinic because the patients can access the treatment at home.
Aims
We aimed to compare rates of smoking cessation in two interventions.

Methods
All patients diagnosed with schizophrenia, bipolar disorders or depression receiving treatment and care for mental illness in outpatient clinics will be eligible for inclusion in the study.

Measures
Primary outcome is changes in number of cigarettes smoked pr. patients per day in mean at 6-month follow-up. Secondary outcome is abstinence from smoking at 6-month follow-up.

Intervention
This is a two-arm randomized controlled trial. 1.Daily video consultants tailored to the individual patients at the start of smoking cessation and the months after. 2. Treatment as usual (tau), consistent of smoking cessation treatment in the community by weekly consultants.

Sample size
The smallest number to conclude will be 53 patients in each of the two arms.
Results
We will start including patients ultimo 2019 and by April 20220 we will have preliminary results.
