Plain English summary of protocol

Background and study aims:
Implantation of a cardioverter defibrillator (ICD) is the established treatment to prevent sudden cardiac death for patients who are at increased risk for developing malignant ventricular arrhythmias (dangerously abnormal rapid heart rhythms). The number of patients implanted with an ICD has increased substantially over the last years. However, some of these ICD patients experience become more anxious and depressed after receiving one or multiple therapeutic shocks. According to an own previous study, 19 % of ICD patients suffer from an anxiety disorder. When asked for treatment wishes most of them preferred a psychotherapeutic group setting. Until now there is no evidence-based treatment available for this patient group. In this pilot study, we want to test the feasibility and success of a short psychotherapeutic group treatment for anxious patients receiving ICD shocks using web-based video conferencing technology.

Who can participate?
ICD patients suffering from anxiety who received one or multiple shocks along with their partners or caregivers

What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 (the control group) are requested to regularly attend medical follow-ups in their cardiology unit and to comply with the medical advices given. Those in group 2 (experimental group) are given the same information in addition to a 10-session-psychotherapy web-based intervention (three single and seven group psychotherapeutic sessions). Anxious, depressive and traumatic symptoms and quality of life are measured using HADS (Hospital Anxiety and Depression Scale), PHQ-D (Patient Health Questionnaire), IES-R (Impact of Event Scale – Revised), GHQ-12 (General Health Questionnaire 12) and SF-36 (Short Form) by all ICD patients and their partners or care givers before the study begins, immediately after treatment, and then 6 months and 12 months after treatment. A year after the intervention group has finished, the web-based psychotherapy intervention will also be offered to the control group.

What are the possible benefits and risks of participating:
Each patient may benefit in terms of improved coping abilities with anxiety and distress in the future by participating in the intervention. There are no increased risks of physical injury or harm.

Where is the study run from?
The study is run by the Department of General Internal Medicine and Psychosomatics, University Medical Care Center Heidelberg. Recruitment is carried out in the outpatient units of University Medical Centers of Heidelberg and Mannheim and of Clinical Center of Ludwigsburg.

When is the study starting and how long is it expected to run for?
June 2015 to March 2017

Who is funding the study?
German Heart Research Foundation (Deutsche Stiftung für Herzforschung (Frankfurt am Main))

Primary study designInterventional
Secondary study designRandomised controlled trial
Study setting(s)Internet/virtual
Study typeTreatment
Scientific titlePsychotherapeutic web-based intervention for anxious patients after receiving shocks by an implantable cardioverter defibrillator: a randomized wait-list controlled pilot study
Study acronymESCAAD (Educated Self-Management for Cardiac Arrhythmia and Anxiety Disorder)
Study objectivesThe primary objective of this pilot study is to examine the acceptability and feasibility of:
1. The study design
2. The experimental psychotherapeutic intervention for anxious patients receiving shocks by an implantable cardioverter defibrillator (ICD)
The intervention consists of three single and seven group sessions. The secondary objective of this pilot study is to examine the preliminary effect of the intervention on patient and caregiver outcomes. The following are the research hypotheses for the study’s secondary objective:
Compared with controls, patients in the intervention group will present:
H1. Fewer anxious symptoms directly after and 6 and 12 months after intervention
H2. Fewer depressive, traumatic symptoms and a better quality of life directly after and 6 and 12 months after intervention
H3. Fewer cardiological treatments in inpatient and outpatient settings
H4. Fewer ICD shocks

Compared with controls, partners of caregivers of ICD patients in the intervention group will present:
H5. Fewer anxious symptoms directly after and 6 and 12 months after intervention
H6. Fewer depressive, traumatic symptoms and a better quality of life directly after and 6 and 12 months after intervention

Health condition(s) or problem(s) studiedICD patients receiving shocks with co-morbid anxiety disorder
InterventionThe intervention consists of three single and seven group psychotherapeutic sessions through a web-based video conference software. For this purpose we created a therapeutic manual including psychoeducational, psychodynamic and behavioral therapeutic elements. The single sessions are to establish a reliable working alliance. The partner or care giver of each study participant is invited to one single session for a closer look on the couple’s perspective. Within the group sessions psychoeducation, relaxation techniques and exposition exercises should help the patients to understand and to deal with their anxiety for ICD shocks and teaches them how to cope with anxiety and stress-provoking situations. Furthermore patients can share their concerns and their experiences with other anxious ICD recipients.
The control group is to adhere closely to cardiologists’ advices, i.e. they get treatment as usual.
Intervention typeBehavioural
Primary outcome measure1. Patients’ satisfaction with the intervention on a visual analogue scale directly after treatment
2. The preliminary effect size for change in anxiety level measured by GAD-7
3. Recruitment rate is determined by measuring the percentage of all ICD patients willing to participate in the intervention to all meeting the inclusion criteria
Secondary outcome measures1. Drop out rates
2. Anxious, depressive and traumatic symptoms and quality of life of ICD patients and their partners or care givers are measured with HADS, PHQ-D, SF-36, GHQ-12 and IES-R before (T0) and after intervention (T1) and at 6 and 12 month follow-up (T2, T3)
3. Number of cardiological treatments in inpatient and outpatient settings and the frequency of ICD shocks at T0, T1, T2 and T3
