Combining Randomized Trials And Registries: A New Paradigm

John S Rumsfeld, MD, PhD

Ultimately, we need clinical trials to know what drugs and medical devices work. Without them, we will not have the evidence we need for clinical practice guidelines, and clinical care will not evolve. But traditional clinical trial approaches are not sustainable – too expensive and too inefficient. The new hope for clinical trials is to […]

Ascertaining ASCERT: How Well Do Registry Data Measure Up to the ‘Bedside Test’?

Øystein Horgmo, BSc

In the ASCERT observational study, stable patients (age 65 or older) with double- or triple-vessel CAD, but not left-main disease, were found to have better long-term survival after CABG than after PCI. ASCERT was a laudable achievement in terms of its scope and the level of collaboration it represents. The ASCERT investigators used inverse probability weighting (propensity […]
