Instrumental variable analysis to compare effectiveness of stents in the extremely elderly

Instrumental variable analysis to compare effectiveness of stents in the extremely elderly

Robert W. Yeh, Samip Vasaiwala, et. al. Evaluating novel therapies is challenging in the extremely elderly. Using an instrumental variable analysis, DES were associated with similar mortality and bleeding and a significant reduction in target vessel revascularization compared with bare metal stents in the extremely elderly. Variation in use rates may be useful as an instrumental variable to facilitate comparative effectiveness in groups underrepresented in randomized trials.

A Prediction Model to Identify Patients at High Risk for 30-Day Readmission After Percutaneous Coronary Intervention

A Prediction Model to Identify Patients at High Risk for 30-Day Readmission After Percutaneous Coronary Intervention

Jason H. Wasfy, Kenneth Rosenfield, et. al. Background: The Affordable Care Act creates financial incentives for hospitals to minimize readmissions shortly after discharge for several conditions, with percutaneous coronary intervention (PCI) to be a target in 2015. We aimed to develop and validate prediction models to assist clinicians and hospitals in identifying patients at highest risk for 30-day readmission after PCI. The risk calculator for this paper is available under the Public Outreach-Risk Calculator menu.

Nonemergency PCI at Hospitals with or without On-Site Cardiac Surgery

Nonemergency PCI at Hospitals with or without On-Site Cardiac Surgery

Alice K. Jacobs M.D., Sharon-Lise T. Normand, Ph.D., et al. – Background: Emergency surgery has become a rare event after percutaneous coronary intervention (PCI). Whether having cardiac-surgery services available on-site is essential for ensuring the best possible outcomes during and after PCI remains uncertain.
