Optimizing Expectations in Cardiac Surgery Patients

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the potential benefit of targeting patients' expectations before coronary artery bypass graft surgery through a brief psychoeducational intervention.

Clinical Trial Description

Coronary artery bypass graft surgery (CABG) is an extremely invasive medical intervention.It is postulated that even under these conditions, treatment outcome is substantially determined by non-specific effects, e.g. patient's expectation. Targeting patients' expectations at an early stage might have potential to optimize outcomes after cardiac surgery. The purpose of this research project is to optimize patients' outcome expectations before undergoing cardiac surgery through a brief psycho-educational program. Using a randomized controlled design, 180 patients who are scheduled to undergo elective CABG are randomly assigned either to standard medical information alone, or to an additional expectation manipulation intervention (EMI) during the two weeks before surgery, or to an attention-control group ("supportive therapy"). The main goal is to enhance positive expectations (surgery 'non-specific effects') about favorable outcome through EMI, about coping abilities to deal with adverse events, and to reduce negative expectations and misconceptions. Assessment takes place before and after EMI, 10 days after surgery and 6 months later; same assessment points are used for the 2 control conditions. Primary outcome is disability, which has been shown to be strongly determined by patient's expectation in previous studies. Moreover, psychological and biological predictors and mediators of treatment success are analyzed. A positive result for this expectation intervention would have major implications for clinical practice. In order to optimize treatment outcome, it is not only necessary to improve the treatment-specific procedures (e.g., cardiac surgery) but also to address non-specific factors such as patients' expectations. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
