Trends in hospital readmission of Medicare-covered patients with heart failure.
This study sought to compare trends in Medicare risk-adjusted, 30-day readmissions following principal heart failure (HF) hospitalizations and other hospitalizations with HF. The investigators found that patients with HF are often hospitalized for other causes, and these hospitalizations have high readmission rates. Policy changes led to decreases in readmission rates for both principal and secondary HF hospitalizations. Readmission rates in both groups remained high, suggesting that initiatives targeting all hospitalized patients with HF continue to be warranted.

Thirty-day postdischarge mortality among black and white patients 65 years and older in the Medicare Hospital Readmissions Reduction Program.
The goal of this cohort study was to determine whether short-term mortality rates increased among black and white adults 65 years and older after initiation of the Medicare Hospital Readmissions Reduction Program (HRRP) and whether trends differed by race. Using an interrupted time-series analysis, the researchers found that short-term post-discharge mortality did not appear to increase for black patients under the HRRP, suggesting that certain value-based payment policies can be implemented without harming black populations. However, mortality seemed to increase for white patients with heart failure; this situation warrants investigation.

Variation in and hospital characteristics associated with the value of care for Medicare beneficiaries with acute myocardial infarction, heart failure, and pneumonia.
The objectives of this study were to investigate the association between hospital-level 30-day risk-standardized mortality rates (RSMRs) and 30-day risk-standardized payments (RSPs) for acute myocardial infarction (AMI), heart failure (HF), and pneumonia (PNA); to characterize patterns of value in care; and to identify hospital characteristics associated with high-value care (defined by having lower than median RSMRs and RSPs).

Medicare accountable care organizations are not associated with reductions in the use of low-value coronary revascularization.
This study examined national Medicare data to determine whether or not Medicare accountable care organizations are associated with reductions in the use of low-value coronary revascularization. The investigators found no association between provider group participation in a Medicare ACO and use of low- or high-value coronary revascularization.

Diagnostic and prognostic value of myocardial blood flow quantification as non-invasive indicator of cardiac allograft vasculopathy.
Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart transplant (OHT) survivors. Effective non-invasive screening methods are needed. The aim of this study was to investigate the added diagnostic and prognostic value of myocardial blood flow (MBF) to standard myocardial perfusion imaging (MPI) with positron emission tomography (PET) for CAV detection.

Trends in troponin-only testing for AMI in academic teaching hospitals and the impact of Choosing Wisely(R).
This study examined the variation in cardiac biomarker testing and the effect of the Choosing Wisely(R) troponin-only recommendation for the diagnosis of acute myocardial infarction (AMI). It concluded that in institutions with low rates of troponin-only testing prior to the Choosing Wisely(R) recommendation, the recommendation was associated with a significant increase in the rate of troponin-only testing.

Favorable cardiovascular health, compression of morbidity, and healthcare costs: forty-year follow-up of the CHA Study (Chicago Heart Association Detection Project in Industry).
The researchers examined the association of cardiovascular health at younger ages with the proportion of life lived free of morbidity, the cumulative burden of morbidity, and average healthcare costs at older ages. They found that individuals in favorable cardiovascular health in early middle age live a longer, healthier life free of all types of morbidity.

Characteristics of automated external defibrillator coverage in Philadelphia, PA, based on land use and estimated risk.
The authors investigated how well the likelihood of out-of-hospital cardiac arrest was met by the supply of automated external defibrillators (AED) in a dense urban environment. This article offers one method by which local officials can use spatial data to prioritize attention for AED placement and coverage.
