BackgroundIn view of the increasing number of implanted cardioverter defibrillators (ICD), the number of people suffering from so-called "multiple ICD shocks" is also increasing. The delivery of more than five shocks (appropriate or inappropriate) in 12 months or three or more shocks (so called multiple shocks) in a short time period (24 hours) leads to an increasing number of patients suffering from severe psychological distress (anxiety disorder, panic disorder, adjustment disorder, post-traumatic stress disorder). Untreated persons show chronic disease processes and a low rate of spontaneous remission and have an increased morbidity and mortality. Few papers have been published concerning the psychotherapeutic treatment for these patients.ObjectiveThe aim of this study is to develop a psychotherapeutic treatment for patients with a post-traumatic stress disorder or adjustment disorder after multiple ICD shocks.DesignExplorative feasibility study: Treatment of 22 patients as a natural design without randomisation and without control group. The period of recruitment was three years, from March 2007 to March 2010. The study consisted of two phases: in the first phase (pilot study) we tested different components and dosages of psychotherapeutic treatments. The final intervention programme is presented in this paper. In the second phase (follow-up study) we assessed the residual post-traumatic stress symptoms in these ICD patients. The time between treatment and follow-up measurement was 12 to 30 months.PopulationThirty-one patients were assigned to the Department of Psychocardiology after multiple shocks. The sample consisted of 22 patients who had a post-traumatic stress disorder or an adjustment disorder and were willing and able to participate. They were invited for psychological treatment. 18 of them could be included into the follow-up study.MethodsAfter the clinical assessment at the beginning and at the end of the inpatient treatment a post-treatment assessment with questionnaires followed. In this follow-up measurement, minimum 12 months after inpatient treatment, posttraumatic stress was assessed using the "Impact of Event Scale" (IES-R).SettingInpatient treatment in a large Heart and Thorax Centre with a Department of Psychocardiology (Kerckhoff Heart Centre).ResultsFrom the 18 patients in the follow-up study no one reported complaints of PTSD. 15 of them reported a high or even a very high decrease of anxiety and avoidance behaviour.ConclusionsThe fist step of the treatment development seems to be successful. It shows encouraging results with an acceptable dosage. The second step of our work is in process now: we evaluate the treatment manual within other clinical institutions and a higher number of psychotherapists. This leads in the consequence to a controlled and randomised comparison study.
