Correlates of Patient Acceptance of the Cardioverter-Defibrillator: Cross-validation of the Florida Patient Acceptance Survey in Danish Patients Correlates of Patient Acceptance of the Cardioverter-Defibrillator: Cross-validation of the Florida Patient Acceptance Survey in Danish Patients The use of cardiac device therapy has entered a new era, as reflected in the increasing number of patients who receive cardioverter-defibrillator therapy, cardiac resynchronization therapy (CRT), or combined therapy The medical benefits of these therapies are well established, but a subset of patients has difficulty with emotional adjustment following device implantation, manifesting itself in increased anxiety, depression, avoidance behaviors, and poor quality of life Device acceptance may comprise one of the keys to identifying patients at high risk for adverse psychological outcome and poor quality of life in clinical practice We examined (1) the validity and reliability of the Florida Patient Acceptance Survey (FPAS) and (2) the correlates of patient acceptance of the cardioverter-defibrillator in a large sample of Danish patients The use of cardiac device therapy has entered a new era, as reflected in the increasing number of patients who receive cardioverter-defibrillator therapy, cardiac resynchronization therapy (CRT), or combined therapy The medical benefits of these therapies are well established, but a subset of patients has difficulty with emotional adjustment following device implantation, manifesting itself in increased anxiety, depression, avoidance behaviors, and poor quality of life Device acceptance may comprise one of the keys to identifying patients at high risk for adverse psychological outcome and poor quality of life in clinical practice We examined (1) the validity and reliability of the Florida Patient Acceptance Survey (FPAS) and (2) the correlates of patient acceptance of the cardioverter-defibrillator in a large sample of Danish patients BACKGROUNDBACKGROUND Dr. Susanne S.
