Wadhera RK, Anderson JD, Yeh RW. High-Risk Percutaneous Coronary Intervention in Public Reporting States: the Evidence, Exclusion of Critically Ill Patients, and Implications. Current heart failure reports. 2017;14(6):514–518. doi:10.1007/s11897-017-0369-1

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.

Cardiovascular (CV) disease is a leading cause of death worldwide, accounting for approximately 31.4% of deaths globally in 2012. It is estimated that, from 1980 to 2000, reduction in total cholesterol accounted for a 33% decrease in coronary heart disease (CHD) deaths in the United States. In other developed countries, similar decreases in CHD deaths (ranging from 19%-46%) have been attributed to reduction in total cholesterol. Low-density lipoprotein cholesterol (LDL-C) has now largely replaced total cholesterol as a risk marker and the primary treatment target for hyperlipidemia. Reduction in LDL-C levels by statin-based therapies has been demonstrated to result in a reduction in the risk of nonfatal CV events and mortality in a continuous and graded manner over a wide range of baseline risk and LDL-C levels. This article provides a review of (1) the relationship between LDL-C and CV risk from a biologic, epidemiologic, and genetic standpoint; (2) evidence-based strategies for LDL-C lowering; (3) lipid-management guidelines; (4) new strategies to further reduce CV risk through LDL-C lowering; and (5) population-level and health-system initiatives aimed at identifying, treating, and lowering lifetime LDL-C exposure.

Pulmonary embolism (PE) is a common cardiovascular condition that represents a spectrum of disorders with a gradient of increased risk of adverse outcomes. The U.S. Surgeon General estimated that approximately 100,000 to 180,000 PE-related deaths occur in the United States annually, and that PE is the most preventable cause of death among hospitalized patients. Risk stratification is critical to identify the patients who may benefit from advanced therapy. This review will provide an overview of PE pathophysiology, evidence-based risk stratification strategies for patients with acute PE, a summary of traditional and novel oral anticoagulant options, and an in-depth discussion on the utilization of advanced therapeutic options, including systemic fibrinolysis, catheter-based pharmacomechanical therapy, and surgical embolectomy.

Bhatia S, Ivers N, Yin CX, Myers D, Nesbitt G, Edwards J, Yared K, Wadhera R, Wu JC, Wong B, et al. Design and methods of the Echo WISELY (Will Inappropriate Scenarios for Echocardiography Lessen SignificantlY) study: An investigator-blinded randomized controlled trial of education and feedback intervention to reduce inappropriate echocardiograms. American heart journal. 2015;170(2):202–9. doi:10.1016/j.ahj.2015.04.022

BACKGROUND: Appropriate use criteria (AUC) for transthoracic echocardiography (TTE) were developed to address concerns regarding inappropriate use of TTE. A previous pilot study suggests that an educational and feedback intervention can reduce inappropriate TTEs ordered by physicians in training. It is unknown if this type of intervention will be effective when targeted at attending level physicians in a variety of clinical settings.

AIMS: The aim of this international, multicenter study is to evaluate the hypothesis that an AUC-based educational and feedback intervention will reduce the proportion of inappropriate echocardiograms ordered by attending physicians in the ambulatory environment.

METHODS: In an ongoing multicentered, investigator-blinded, randomized controlled trial across Canada and the United States, cardiologists and primary care physicians practicing in the ambulatory setting will be enrolled. The intervention arm will receive (1) a lecture outlining the AUC and most recent available evidence highlighting appropriate use of TTE, (2) access to the American Society of Echocardiography mobile phone app, and (3) individualized feedback reports e-mailed monthly summarizing TTE ordering behavior including information on inappropriate TTEs and brief explanations of the inappropriate designation. The control group will receive no education on TTE appropriate use and order TTEs as usual practice.

CONCLUSIONS: The Echo WISELY (Will Inappropriate Scenarios for Echocardiography Lessen Significantly in an education RCT) study is the first multicenter randomized trial of an AUC-based educational intervention. The study will examine whether an education and feedback intervention will reduce the rate of outpatient inappropriate TTEs ordered by attending level cardiologists and primary care physicians (www.clinicaltrials.gov identifier NCT02038101).
