ObjectiveTo develop and implement a comprehensive transesophageal echocardiography (TEE) quality improvement (QI) program and assess for potential improvements in TEE performed by cardiac anesthesiologists.DesignProspective institutionally approved QI program.SettingAcademic tertiary care center.ParticipantsThe study comprised cardiac anesthesiologists.InterventionsAn instrument comprising 15 quality measures to assess TEE examinations pre- and post-cardiopulmonary bypass (CPB) was developed for the present study. TEE examinations before the introduction of the QI program were assessed retrospectively, and examinations performed after its introduction were reviewed prospectively over a 2-year period.Measurements And Main ResultsA total of 118 TEE studies were analyzed, 48 and 70 studies before and after introduction of the TEE QI program, respectively. Half of the studies were performed pre-CPB, and half of them were performed post-CPB. Multivariate linear mixed regression models were used to assess the effect of the QI program. Interrater variability was assessed among internal reviewers by means of the Shrout-Fleiss reliability intraclass correlation coefficient. Five quality measures demonstrated a significant improvement in studies after CPB after implementation, including 3 imaging criteria (left ventricle, tricuspid valve, and pulmonary artery) and 2 documentation criteria (completeness of demographic/clinical data and timely reporting of documentation). The inter-rater variability analysis yielded an average intraclass correlation coefficient of 0.90 before and 0.78 after the QI program initiation, consistent with excellent agreement among the 4 reviewers.ConclusionsThe present study demonstrated the ability to create and implement a formal QI program for intraoperative TEE in an academic tertiary care cardiac surgical group. The initial data showed significant improvement in several quality measures related to TEE performance.Copyright © 2020 Elsevier Inc. All rights reserved.
