Impact of acuity circles on outcomes for pediatric liver transplant candidates.
In December 2018, UNOS approved an allocation scheme based on recipients' geographic distance from a deceased donor ("acuity circles"). Previous analyses suggested acuity circles (AC) would reduce waitlist mortality overall, but their impact on pediatric subgroups was not considered. In this study, the investigators applied Scientific Registry of Transplant Recipients data from 2011-2016 towards the Liver Simulated Allocation Model (LSAM) to compare outcomes by age and illness severity for the UNOS-approved AC and the existing Donor Service Area (DSA)/Region-based allocation schemes.

Projected 20- and 30-year outcomes for pediatric liver transplant recipients in the United States.
Researchers aimed to use national registry data and parametric models to project 20- and 30-year post-transplant outcomes for recently transplanted pediatric liver transplant (LT) recipients. Using Scientific Registry of Transplant Recipients data, they found that projected long-term outcomes for recently transplanted pediatric LT recipients are excellent, reflective of substantial improvements in medical care, and informative for physician-patient education and decision making in the current era.

Association of use of an intravascular microaxial left ventricular assist device vs intra-aortic balloon pump with in-hospital mortality and major bleeding among patients with acute myocardial infarction complicated by cardiogenic shock.
This study examines outcomes among patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) complicated by cardiogenic shock. Two interventions are compared: intravascular microaxial left ventricular assist devices (LVADs) versus intra-aortic balloon pumps (IABPs). The American College of Cardiology’s National Cardiovascular Data Registry was used to identify patients with AMI complicated by cardiogenic shock from hospitals participating in the CathPCI and Chest Pain-MI registries and identified 28,304 patients. Over the study period (2015 to 2017), LVAD was used in 6.2% of patients and IABP in 29.9%. LVAD was shown to have higher rates of in-hospital death and major bleeding complications compared to IABP.

To share is human! Advancing evidence into practice through a national repository of interoperable clinical decision support.
The purpose of this study was to describe how a national repository of clinical decision support (CDS) can serve as a public resource for healthcare systems, academic researchers, and informaticists seeking to share and reuse CDS knowledge resources. AHRQ’s CDS Connect has provided a functional platform where CDS developers are actively sharing their work. CDS sharing may lead to improved implementation efficiency through numerous pathways, and further research is ongoing to quantify efficiencies gained.

Rhythm control versus rate control in patients with atrial fibrillation and heart failure with preserved ejection fraction: insights from get with the guidelines-heart failure.
Researchers analyzed the Get With The Guidelines - Heart Failure (GWTG-HF) registry linked to Medicare claims data to describe current treatments for rate versus rhythm control and subsequent outcomes in patients with heart failure with preserved ejection fraction and atrial fibrillation. They found that rhythm control in patients aged 65 and older with heart failure with preserved ejection fraction and AF was associated with a lower risk of one-year all-cause mortality. They recommended future prospective randomized studies to explore this potential benefit.

The Systematic Review Data Repository (SRDR): descriptive characteristics of publicly available data and opportunities for research.
Funded by the US Agency for Healthcare Research and Quality (AHRQ), the Systematic Review Data Repository (SRDR) is a free, web-based, open-source, data management and archival platform for reviews. The objectives of this study were to describe (1) the current extent of usage of SRDR and (2) the characteristics of all projects with publicly available data on the SRDR website.

Harmonized outcome measures for use in asthma patient registries and clinical practice.
The purpose of this project was to develop a minimum set of patient and provider relevant standardized outcome measures that could be collected in asthma patient registries and clinical practice. Categorizing outcome measures using AHRQ’s supported Outcome Measures Framework (OMF), a minimum set of 21 broadly relevant measures from 13 registries was identified. Routine and consistent collection of these measures in registries and in other systems would support creation of a national research infrastructure to efficiently address new questions and improve patient management and outcomes.

Predictors of response outcomes for research recruitment through a central cancer registry: evidence from 17 recruitment efforts for population-based studies.
The authors conducted multivariable mixed-effects logistic regression to identify case and study characteristics associated with making contact with and obtaining cooperation of Utah cancer cases. They found that characteristics associated with lower odds of contact included Hispanic ethnicity, nonwhite race, and younger age at contact. Years since diagnosis was inversely associated with making contact. Increased odds of cooperation were associated with including a questionnaire, postage stamps, and incentives. They concluded that obtaining high response is challenging, but study features identified in this analysis support better results when recruiting through central cancer registries.

The ORBIT bleeding score: a simple bedside score to assess bleeding risk in atrial fibrillation.
The researchers sought to develop and validate a novel bleeding risk score using routinely available clinical information to predict major bleeding in a large, community-based in atrial fibrillation (AF) population. They concluded that their five-element ORBIT bleeding risk score had better ability to predict major bleeding in AF patients when compared with HAS-BLED and ATRIA risk scores.

Catheter ablation of atrial fibrillation in U.S. community practice--results from Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF).
The objective of the study was to describe the utilization of catheter ablation in a contemporary U.S. clinical practice and describe the characteristics and subsequent outcomes in patients undergoing AF ablation in community practice. It found that there were no clinically relevant differences in oral anticoagulation post-AF ablation or differences in outcomes in patients with or without previous AF catheter ablation.

Physician practices regarding contraindications to oral anticoagulation in atrial fibrillation: findings from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) registry.
This study describes the frequencies of and factors associated with oral anticoagulation (OAC) contraindications in clinical practice for patients with atrial fibrillation (AF). Contraindications to OAC therapy among patients with AF are common but subjective. Many patients with reported contraindications were receiving OAC, suggesting that the perceived benefits outweighed the potential harm posed by the relative contraindication.
