In this month's podcast, Shelley S. Magill, MD, PhD, of the Centers for Disease Control and Prevention (CDC) provides an introduction to the new three-tier, adult surveillance definition algorithm for ventilator-associated events (VAE) developed by the multi-organization Ventilator-Associated Pneumonia (VAP) Surveillance Definiition Working Group and implemented in January 2013 by the CDC's National Healthcare Safety Network. The Executive Summary of the report appears in this month's issue and is being co-published with other Working Group society publisher journals. CHEST Podcast Editor, D. Kyle Hogarth, MD, FCCP, moderates the discussion with Dr. Magill and editorialist Craig M. Lilly, MD, FCCP, to debate the merits of the new focus on VAE vs. VAP
