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

Nursing homes that increased the proportion of Medicare days saw gains in quality outcomes for long-stay residents.
The authors examined nationwide facility-level nursing home data for the period 2007-2010. They found that increasing the proportion of Medicare-covered patient days in a nursing home was significantly associated with improvements in the quality of daily pain, pressure ulcers, and performing activities of daily living.

The comparative effectiveness of biologics among older adults and disabled rheumatoid arthritis patients in the Medicare population.
Older and disabled rheumatoid arthritis (RA) patients are often not present in large numbers in clinical trials or registries. Using a novel, claims-based clinical effectiveness algorithm with the potential to compare the effectiveness of different biologics among this population using large administrative databases, researchers found that abatacept, adalimumab and etanercept are more effective than infliximab among RA patients initiating biologics.

Association of patient enrollment in Medicare Part D with outcomes after acute myocardial infarction.
The researchers investigated whether enrollment versus nonenrollment in Medicare's prescription drug plan (Part D) is associated with better outcomes after acute myocardial infarction (AMI). They found that only half of Medicare-insured patients with AMI were enrolled in Part D by hospital discharge, and their 30-day and 1-year adjusted outcomes did not differ substantially from nonenrollees.

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.
