The Echocardiography Appropriate Use Criteria (EAUC) are a set of indications for transthoracic echocardiography (TTE) developed to guide physician decision making around ordering of TTE. In this study, an automated rule-based method for processing "indications" listed within TTE reports and classification into one of the major EAUC categories was developed and validated against a clinician-annotated reference standard. The system performed at a comparable level to trained physicians allowing for the automated classification of more than 30,000 TTE indications from a public database in less than ten minutes. The most common indication for TTE was Valvular assessment closely followed by General. Hypertension/Heart Failure/Cardiomyopathy, Acute, and Cardiac Structure assessment each contributed more than ten percent within this patient population. These results suggest potential for automated approaches for tracking appropriate use of TTE, as well as guide the development of systems for prospectively identifying when TTE use is recommended.

PURPOSE OF REVIEW: Public reporting of outcomes for percutaneous coronary intervention (PCI) is used in some states to drive improvements in care delivery and performance. However, a growing body of evidence suggests unintended consequences, particularly provider aversion to performing PCI in high-risk patients.
RECENT FINDINGS: There is mixed evidence regarding the impact of PCI public reporting on patient outcomes. In addition, providers in public reporting states likely have a higher threshold or potentially avoid performing PCI on high-risk patients, such as those with cardiogenic shock. The exclusion of patients with refractory cardiogenic shock from public reports in New York state has reduced provider risk aversion. Though this represents a step in the right direction, other strategies are needed to diminish continued provider risk aversion and strengthen PCI care quality. Public reporting initiatives for PCI are beginning to proliferate nationally. However, the challenge of fostering the positive of aspects of reporting, which incentivize improved care quality and procedural performance, while ensuring that high-risk patients continue to receive appropriate care remains. It is imperative that policymakers and cardiologists continue to develop innovative solutions that address risk aversive provider behaviors towards high-risk patients.
BACKGROUND: Appropriate use criteria (AUC) have defined transthoracic echocardiogram (TTE) indications for which there is a clear lack of benefit as rarely appropriate (rA).
OBJECTIVES: This study sought to investigate the impact of an AUC-based educational intervention on outpatient TTE ordering by cardiologists and primary care providers.
METHODS: The authors conducted a prospective, investigator-blinded, multicenter, randomized controlled trial of an AUC-based educational intervention aimed at reducing rA outpatient TTEs. The study was conducted at 8 hospitals across 2 countries. The authors randomized cardiologists and primary care providers to receive either intervention or control (no intervention). The primary outcome measure was the proportion of rA TTEs.
RESULTS: One hundred and ninety-six physicians were randomized, and 179 were included in the analysis. From December 2014 to April 2016, the authors assessed 14,697 TTEs for appropriateness, of which 99% were classifiable using the 2011 AUC. The mean proportion of rA TTEs was significantly lower in the intervention versus the control group (8.8% vs. 10.1%; odds ratio [OR]: 0.75; 95% confidence interval [CI]: 0.57 to 0.99; p = 0.039). In physicians who ordered, on average, at least 1 TTE per month, there was a significantly lower proportion of rA TTEs in the intervention versus the control group (8.6% vs. 11.1%; OR: 0.76; 95% CI: 0.57 to 0.99; p = 0.047). There was no difference in the TTE ordering volume between the intervention and control groups (mean 77.7 ± 89.3 vs. 85.4 ± 111.4; p = 0.83).
CONCLUSIONS: An educational intervention reduced the number of rA TTEs ordered by attending physicians in a variety of ambulatory care environments. This may prove to be an effective strategy to improve the use of imaging.
