[Implementation of a Behavioral Medicine Oriented Concept in Cardiological Rehabilitation]. / Implementierung einer Verhaltensmedizinisch Orientierten Rehabilitation in der Kardiologie.

This study examined the implementation of a behavioral medicine oriented rehabilitation concept in a cardiological rehabilitation clinic. Psychotherapeutic interventions were based on an Acceptance and Commitment Therapy framework. Participants were treated in a behavioral cardiac rehabilitation program (BCR; n=149), or in a conventional cardiac rehabilitation program (CCR, n=100). We tested and compared the reach of the targeted group, the fidelity of the concept implementation in the BCR, as well as the completeness of the intervention (dose delivered) and the patient-reported behavioral medical treatment dose (dose received). Changes from beginning of rehabilitation until discharge with regard to mental and physical performance were assessed in both groups. BCR-patients were more impaired than CCR-patients, and they confirmed more behavioral medical content, a higher consistency of the behavioral medical strategy and a stronger gain of competence. Adherence ratings indicated a largely accurate implementation of the intervention. In both groups, depression, somatization, anxiety, heart anxiety, exercise self-efficacy expectation, and maximum power in bicycle ergometry improved statistically significant from admission to discharge. Large or nearly large effect sizes were found for avoidance behavior (d=0.78), somatization (d=0.82), depression (d=0.76), anxiety (d=0.72) and performance in bicycle ergometry (d=0.86) in the BCR. A further evaluation by means of a randomized controlled trial should follow this implementation study.

Outcomes of cardiac rehabilitation with versus without a follow-up intervention rendered by telephone (Luebeck follow-up trial): overall and gender-specific effects.

The effects of a nurse-managed secondary prevention program for patients after acute cardiac events were examined. Special interest was given to gender-specific results. The design was a prospective, randomized, controlled trial involving 343 patients following 3 weeks of inpatient cardiac rehabilitation, randomly assigned to either of two study groups. Patients in the treatment group were contacted monthly by phone over 1 year. The main goals of the intervention were the reduction of behavioural coronary risk factors and enhancing quality of life. The program was conducted by specially trained nurses. The control group received written information only. Primary outcome was the Framingham risk score. Follow-up examination after 12 months was completed by 297 patients. Patients in the intervention group showed lower Framingham risk scores as compared to controls. Separate analyses by sex revealed that this was mostly due to the men in the sample. Women, on the other hand, showed a significant rise of clinically relevant anxiety/depressiveness in the control but not in the intervention group; in males there were no differences between study conditions. In conclusion, telephone counselling by specially trained nurses seems a cost-effective way to achieve a lasting reduction in cardiac risk factors and to maintain the effects of cardiac rehabilitation.
