Over the past two decades, Transthoracic echocardiogram (TTE) orders increased at a rate of about 5-8% per year, and 25% of these orders are composed of repeat TTE’s. However, only a third of repeat orders are considered clinically appropriate. Our study leveraged the electronic medical record (EMR) to reduce repeat TTEs. We created a best practice alert (BPA) within the EMR throughout the Johns Hopkins Health System (JHHS). The BPA alerts when a clinician orders a TTE on a hospitalized patient who already had one in the system within the prior 3 months. The BPA displays the findings from the most recent TTE and asks the clinician if they would like to continue with the order or cancel it. If a provider continues with the order, a free text reason must be entered to explain the rationale for continuing with the order. Since initiation of the BPA, 34.3% of clinicians opted to discontinue the order, and 65.7% chose to continue. Readmission rates and length of stay (LOS) served as balancing measures. Patients who underwent repeat TTE testing had a 20% 30-day readmission rate as compared to 19% readmission rate in those who did not have repeat testing (p-value 0.88). The average LOS for patients who underwent repeat TTE was 11.4 days vs. an average LOS of 9.3 days for patients who did not undergo repeat TTE (p-value 0.41). The BPA designed within the EMR successfully reduced repeat TTEs without leading to increased readmissions or LOS.
