Patterns of institutional review of percutaneous coronary intervention appropriateness and the effect on quality of care and clinical outcomes.
The researchers sought to determine whether internal review of percutaneous coronary intervention (PCI) appropriateness using appropriate use criteria is associated with differences in procedural appropriateness, quality of care, and patient outcomes. They concluded that there was a modest association between procedural appropriateness and clinical outcomes and a similarly modest correlation between nonacute PCI volume and procedural appropriateness.

Hospital variation in outcomes for transcatheter aortic valve replacement among Medicare beneficiaries, 2011 to 2013.
The researchers studied hospital performance on transcatheter aortic valve replacement (TAVR) using data from all Medicare fee-for-service (FFS) beneficiaries 65 years of age and older who underwent TAVR from January 1, 2011, to December 31, 2013. They found that for an individual patient, the between-hospital variation translates to a great than 2-fold higher risk of dying within 30 days for a patient undergoing TAVR at a hospital 1 SD above the national average compared with undergoing TAVR at a hospital 1 SD below; the between-hospital variation was

Effect of the 2014 atrial fibrillation guideline revisions on the proportion of patients recommended for oral anticoagulation.
Researchers assessed the potential effect of a new guideline for atrial fibrillation (AF) by comparing the proportion of patients with AF recommended for oral anticoagulation (OAC) under the 2011 and 2014 guidelines. They found that two-thirds of patients with AF who were previously not recommended for OAC are newly recommended under the 2014 guideline. They advised future studies evaluating longitudinal changes in anticoagulation treatment patterns and outcomes among patients reclassified by the new guidelines.

Policies allowing family presence during resuscitation and patterns of care during in-hospital cardiac arrest.
A growing number of hospitals have begun to implement policies allowing for family presence during resuscitation (FPDR). However, the overall safety of these policies and their effect on resuscitation care is unknown. This study suggests that hospitals with an FPDR policy generally have no statistically significant differences in outcomes and processes of care as hospitals without this policy.

Early mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.
The researchers compared early mortality after aortic valve replacement (AVR) between the recipients of mechanical and bioprosthetic aortic valves. Among 66,453 Medicare beneficiaries who received AVRs, use of mechanical valves was associated with a higher risk for death on the date of surgery and within 30 days compared with the bioprosthetic aortic valves. However, this applied only to those who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.

Demographics, bystander CPR, and AED use in out-of-hospital pediatric arrests.
The researchers sought to determine if the 2005 American Heart Association guidelines for routine use of automated external defibrillators during pediatric out-of-hospital arrest are used during resuscitations. They found that young children suffering from presumed out-of-hospital cardiac arrests are less likely to have a shockable rhythm when compared to adults, and are less likely to have an AED used during resuscitation.

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.
