Knowledge, attitude, and behavior in patients with atrial fibrillation undergoing radiofrequency catheter ablation

PURPOSE: Catheter ablation for atrial fibrillation (AF) has become a widely accepted procedure in most of the large cardiac centers throughout the world. However, little is known regarding the knowledge, attitude, and behavior (KAB) of AF patients undergoing radiofrequency catheter ablation (RFCA). Our purpose is to investigate the status and influencing factors of KAB in these patients. METHODS: We conducted a KAB survey utilizing specifically designed questionnaires among hospitalized AF patients undergoing RFCA from July 2008 to April 2009. RESULTS: A total of 116 AF participants were enrolled and 113 were effective sample, the response rate was 97%. Only 47% of the participants answered questions regarding knowledge about AF correctly. Knowledge deficits were greater in male patients, poorly educated and first-time RFCA patients. With regard to attitude, 45% of participants considered daily pulse examination to be unnecessary. Higher knowledge scores, persistent AF and AF recurrence were positive predictors of attitude. Despite adherence to take medication was high, more than half of the participants demonstrated poor monitor behavior. Knowledge, attitude, and the number of previous attempts at RFCA were factors affecting the self-management behavior. CONCLUSIONS: AF patients undergoing RFCA have knowledge deficits in general and there is a lack of consistency among their KAB. In order to establish a better attitude and self-management behavior, AF patients undergoing RFCA need comprehensive education by the KAB questionnaire according to the KAB theory.
