OPTIMA: Psychological Distress and the Effect of Intensive Group Based Cognitive Therapy in Patients With Newly Diagnosed Ischemic Heart Disease

OPTIMA: Psychological Distress and the Effect of Intensive Group Based Cognitive Therapy in Patients With Newly Diagnosed Ischemic Heart Disease: A Randomised Controlled Trial Protocol

The overall objectives of the Optima project is to: (1) Compare the effect of standardized group based cognitive therapy and cardiac rehabilitation versus usual cardiac rehabilitation in patients with sign of psychological distress measured by a questionnaire (HADS score), (2) To investigate spontaneous variation in psychological distress with HADS over time in order to optimize time of measuring HADS. (3) To investigate if the intervention can be implemented to other cardiac rehabilitation sites with the same effect as on BFH (that it is not person dependent).

HYPOTHESIS: There will be a significant difference in anxiety and depression score between intervention and usual care groups after intervention, in favor of the intervention group.

METHODS: Optima is a multi-center, prospective, randomized clinical trial in patients with newly diagnosed ischemic heart disease (IHD) or heart valve replacement, and concomitant significant score of psychological distress using the Hospital Anxiety and Depression Score (HADS) (HADS A(Anxiety) /D(Depression) ≥8 or HADS>15), age <65 years. Patients with HADS D≥11 and Beck Depression Inventory (BDI)>17 are evaluated by psychiatrists to offer the best treatment. 148 patients will be randomized to either intervention or control group. All patients are offered usual cardiac rehabilitation, and in addition, the intervention group is offered standardized group based cognitive therapy with the participation of maximum four patients, consisting of 5 sessions (each 2 hours) performed by a trained cardiac rehabilitation nurse. The intervention was developed on experiences from a Liaison nurse, who offered up to five individual consultations to patients with psychological distress. Together with a psychologist specialized in cognitive therapy the investigators developed a program based on cognitive behavioral methods from cognitive therapy as well as Acceptance and commitment therapy (ACT). Each session consists of specific cognitive models, which the patient can use in everyday life.

INTERVENTION: Patients are informed about the Optima program in the inclusion interview, and patients are participating in groups of maximum 4 persons. Each of the 5 session has a duration of 1,5 - 2 hours.

The psychologist have developed the content of each session, with attention to thoughts and feelings regarding the current situation after a heart-condition, and the effects on life conditions. Patients get the tools to overcoming the difficulties, they experience, f.x. anxiety and stress.

When other hospitals are joining the Optima project, the project nurse and psychologist are training the hospital staff as well as supervising.

The session are planned as follows Session 1: Identifying your values

• What is important in my life?
• How has my heart-condition effected my life?
• Where do I want to be in my life? And what challenges it? Session 2: Anxiety and techniques to reduce anxiety
• What is anxiety?
• Anxiety and heart symptoms
• Circle of anxiety
• Techniques to reduce anxiety, relaxation and breathing Session 3: Consequences of own behavior and behavioral analysis
• Behavior that reduces self-expression
• Heart disease and behavior
• Consequences of own behavior Session 4: Concerns and strategies for dealing with them
• What are concerns?
• The Worry Tree and how to use it.
• Strategies for handling concerns. Session 5: The balance between demands and capacity
• Thoughts about the future
• Working life, relations and family

Sessions are followed up with two interviews after 3 and 6 months, where the following are assessed:

• The Hospital Anxiety and Depression Scale (HADS) score
• Heart-related Quality of Life (HeartQoL)
• Blood samples
• Clinical assessment: Functional Classification of Angina (CCS), New York Heart Association (NYHA) score, Blood pressure, medical status, smoking/nonsmoking, weight, physical activity (self-assessment) cardiovascular readmissions
• Employment status
• return to work
• present psychosocial status

QUESTIONNAIRES: Questionnaires include validated assessment tools:

HADS: The Hospital Anxiety and Depression Scale (HADS) is a 14-item questionnaire that assesses anxiety and depression level in medically ill persons who are not admitted in psychiatric wards. The scale range is from 0 to 42, the lesser the score, the lesser signs of psychological distress. The scale offers two scores, HADS-A and HADS-D, and consists of seven questions to assess anxiety and seven questions to assess depression.

HeartQol: Heart-related Quality of Life is a disease-specific questionnaire that measures health-related quality of life in patients with heart disease. The questionnaire consists of 14 items and provides two subscales: a 10-item physical subscale and a 4-item emotional subscale, which are scored from 0 to 3. Higher scores indicating better HRQL.

Also, a questionnaire that measures present psychosocial status/situation is used. The questionnaire is based on clinical experience.
