The magnitude error and phase error (MEPE) in the transfer function of a stepped-frequency synthetic aperture radar (SAR) system results in a periodic MEPE in the synthesized wideband waveform (SWW), which induces the grating lobes in the high-resolution range profile (HRRP). In this paper, a robust data-driven grating lobe suppression (GLS) method is proposed. Based on a contrast-based error estimation method and the grating lobes of the brightest scatterers in the SAR image, the periodic MEPE can be robustly estimated using the proposed method...

OBJECTIVE: The introduction of the Hospital Readmission Reduction Program (HRRP) has led to renewed interest in developing strategies to reduce 30-day readmissions among patients with heart failure (HF). In this study, a model was developed to investigate whether the addition of ivabradine to a standard-of-care (SoC) treatment regimen for patients with HF would reduce HRRP penalties incurred by a hypothetical hospital with excess 30-day readmissions. RESEARCH DESIGN: A model using a Monte Carlo simulation framework was developed...

OBJECTIVES: To determine the opinions of US hospital leadership on the Hospital Readmissions Reduction Program (HRRP), a national mandatory penalty-for-performance program. STUDY DESIGN: We developed a survey about federal readmission policies. We used a stratified sampling design to oversample hospitals in the highest and lowest quintile of performance on readmissions, and hospitals serving a high proportion of minority patients. METHODS: We surveyed leadership at 1600 US acute care hospitals that were subject to the HRRP, and achieved a 62% response rate...

Interactions of rhizobia with legumes establish the chronic intracellular infection that underlies symbiosis. Within nodules of inverted repeat-lacking clade (IRLC) legumes, rhizobia differentiate into nitrogen-fixing bacteroids. This terminal differentiation is driven by host nodule-specific cysteine-rich (NCR) peptides that orchestrate the adaptation of free-living bacteria into intracellular residents. Medicago truncatula encodes a family of >700 NCR peptides that have conserved cysteine motifs. NCR247 is a cationic peptide with four cysteines that can form two intramolecular disulfide bonds in the oxidized forms...

There is an active public debate about whether patients' socioeconomic status should be included in the readmission measures used to determine penalties in Medicare's Hospital Readmissions Reduction Program (HRRP). Using the current Centers for Medicare and Medicaid Services methodology, we compared risk-standardized readmission rates for hospitals caring for high and low proportions of patients of low socioeconomic status (as defined by their Medicaid status or neighborhood income). We then calculated risk-standardized readmission rates after additionally adjusting for patients' socioeconomic status...

OBJECTIVES: This paper analyzes whether hospital participation in an accountable care organization (ACO) impacts a hospital's quality improvement and cost reduction outcomes in other value-based purchasing (VBP) programs, including the Hospital Value-Based Purchasing Program (HVBP), the Hospital Readmissions Reduction Program (HRRP), and the Hospital-Acquired Conditions (HAC) Reduction Program. STUDY DESIGN: Using VBP performance data and Leavitt Partners' ACO data, 2 analyses were performed: 1) a descriptive comparison of VBP performance of hospital ACOs compared with non-ACO hospitals, and 2) a longitudinal analysis of hospitals that became part of an ACO during the second year of performance data...

To incentivize hospitals to provide better quality care at a lower cost, the Affordable Care Act of 2010 included the Hospital Readmissions Reduction Program (HRRP), which reduces payments to hospitals with excess 30-day readmissions for Medicare patients treated for certain conditions. We use triple difference estimation to identify the HRRP's effects in Virginia hospitals; this method estimates the difference in changes in readmission over time between patients targeted by the policy and a comparison group of patients and then compares those difference-in-differences estimates in patients treated at hospitals with readmission rates above the national average (i...

BACKGROUND: Surgical readmissions are common, costly, and the focus of national quality improvement efforts. Given the relatively high readmission rates among vascular patients, pay-for-performance initiatives such as Medicare's Hospital Readmissions Reduction Program (HRRP) have targeted vascular surgery for increased scrutiny in the near future. Yet, the extent to which institutional case mix influences hospital profiling remains unexplored. We sought to evaluate whether higher readmission rates in vascular surgery are a reflection of worse performance or of treating sicker patients...

Traditional monopulse angle estimations are mainly based on phase comparison and amplitude comparison methods, which are commonly adopted in narrowband radars. In modern radar systems, wideband radars are becoming more and more important, while the angle estimation for wideband signals is little studied in previous works. As noise in wideband radars has larger bandwidth than narrowband radars, the challenge lies in the accumulation of energy from the high resolution range profile (HRRP) of monopulse. In wideband radars, linear frequency modulated (LFM) signals are frequently utilized...

BACKGROUND: Penalties from the Hospital Readmission Reduction Program can push financially strained, vulnerable patient-serving hospitals into additional hardship. In this study, we quantified the association between vulnerable hospitals and readmissions and examined the respective contributions of patient- and hospital-related factors. METHODS: A total of 110,857 patients who underwent major cancer operations were identified from the 2004-2011 State Inpatient Database of California...

Of those patients hospitalized for an exacerbation of COPD, one in five will require rehospitalization within 30 days. Many developed countries are now implementing policies to increase care quality while controlling costs for COPD, known as value-based health care. In the United States, COPD is part of Medicare's Hospital Readmissions Reduction Program (HRRP), which penalizes hospitals for excess 30-day, all-cause readmissions after a hospitalization for an acute exacerbation of COPD, despite minimal evidence to guide hospitals on how to reduce readmissions...

BACKGROUND: Medicare's Hospital Readmission Reduction Program (HRRP) created clear financial incentives for hospitals to prevent readmissions. Although existing evidence suggests readmission rates have been declining, the direct contribution of this policy to these reductions is unclear. Furthermore, it is unknown whether HRRP has produced unintended effects, including the substitution of outpatient hospital care for readmissions. OBJECTIVES: To determine the effect of HRRP in New York State on both the likelihood of being readmitted and returning to hospital emergency department (ED) care within 30 days of discharge...

OBJECTIVE: To assess whether differences in readmission rates between safety-net hospitals (SNH) and non-SNHs are due to differences in hospital quality, and to compare the results of hospital profiling with and without SES adjustment. BACKGROUND: In response to concerns that quality measures unfairly penalizes SNH, NQF recently recommended that performance measures adjust for socioeconomic status (SES) when SES is a risk factor for poor patient outcomes. METHODS: Multivariate regression was used to examine the association between SNH status and 30-day readmission after major surgery...

RATIONALE: New risk factors for readmission within 30 days of hospital discharge for patients with chronic obstructive pulmonary disease (COPD) need to be identified in view of the lack of efficacy of current interventions for preventing readmission. OBJECTIVES: To identify novel risk predictors for 30-day readmission among COPD index admissions at high risk of readmission. METHODS: For this analysis, we used the fiscal year 2015 hospital-specific Medicare Hospital Readmissions Reduction Program workbook for Staten Island University Hospital (Staten Island, NY)...

The Medicare Hospital Readmissions Reduction Program (HRRP), an initiative of the Affordable Care Act, imposes considerable financial penalties on hospitals with excess thirty-day readmissions for patients with selected high-volume conditions. We investigated the intended impact of the program by examining changes in thirty-day readmissions among Medicare patients admitted for three conditions targeted by the program in New York State, compared to Medicare patients with other conditions and with privately insured patients, before and after the program's introduction...
