Feasibility and clinical benefit of cognitive–behavioral intervention for preparing patients for transesophageal echocardiography

Objective: Despite premedication, anxiety in patients undergoing transesophageal echocardiography (TEE) is prevalent, often causing adverse physiological and psychological effects and contributing to decreased patient compliance. We aimed to evaluate the feasibility of cognitive–behavioral intervention (CBI) in patients undergoing TEE and to assess its impact on the severity of anxiety, patient’s and physician’s comfort, and administered dose of sedatives. Methods: Our study was designed as a prospective, single-center, single-blinded, case-controlled pilot study. The study group comprised 49 patients (26 men, 66±8 years old) referred for TEE. Before the examination, 26 randomly selected patients underwent CBI. Sedatives were administered, if necessary. After the examination, patient anxiety and patient’s and physician’s comfort were evaluated using dedicated questionnaires and scores. Intergroup comparison was performed using Student’s t-test for independent variables and Mann–Whitney U test and Pearson’s chi-square test or Fisher’s exact test for categorical variables. Results: The mean level of pre-TEE distress and anxiety were significantly lower in patients receiving CBI than in those without intervention (p=0.022). Furthermore, the application of CBI significantly reduced patient’s discomfort (p
