Improved Screening Reduces Transesophageal Study Cancellations at a Large Tertiary Israeli Medical Center

Cancellation of transesophageal echocardiography (TEE) tests leads to inefficient use of echocardiography laboratory (echo lab) time and wastes resources. To identify the causes of same-day TEE cancellations in hospitalized patients, to formulate a TEE order screening protocol, and to evaluate its efficacy at implementation. We performed a prospective analysis of inpatients referred to a single tertiary hospital echo lab for TEE study by inpatient wards. A comprehensive screening protocol emphasizing active participation of all links directly involved in the chain of inpatient TEE referral was developed and implemented. Comparison of pre- and post-implementation of the new screening protocol on two consecutive periods of 6 months on TEE cancellation rates out of total ordered TEEs stratified by cause categories was performed. : In total, 304 inpatient TEE procedures were ordered during the initial observation period; 54(17.8%) were canceled on the same day. The most common cancellation reasons were equally respiratory distress and patient not in fasted state (20.4% of total cancellations and 3.6% of all scheduled TEEs for each cause). Following implementation of the new screening process, total TEEs ordered (192) and cancelled (16) dropped significantly. A decrease in the rate of each cancellation category was observed, with statistical significance achieved for the overall cancellation rate (8.3% vs. 17.8%, P = 0.003), but not for the individual cancellation categories in split analysis. A concerted effort to implement a comprehensive screening questionnaire significantly reduced same-day cancellations of scheduled TEEs.
