Welcome to the 2013 Annual Research Meeting! We’re blogging from Baltimore as we join researchers, policymakers, and practitioners to kick off the premier forum for health services research. This year’s ARM is an exciting one for us — we received 20 percent more abstracts submissions than ever, and with more than 2,600 attendees, this is also our biggest ARM to date — thank you for being a part of it! To add to the excitement, it’s our 30th Annual Research Meeting. We are celebrating with a series of special sessions on how far the field has come over the past 30 years and emerging research that will shape our future. Though today kicks off the official meeting, more than 500 people participated in yesterday’s Methods Seminars and Interest Group meetings, sharing emerging research findings in specialized areas. If you haven’t stopped at registration yet, be sure to pick up all of your meeting materials in the Baltimore Convention Center’s Charles Street Lobby. We’ll be open from 7:00 a.m.-6:00 p.m. today and Monday, and 7:00 a.m.-2:00 p.m. on Tuesday. We’re looking forward to a few highlights on day one: Opening Plenary: Will the Civil War over Health Reform Ever End? 12:45-2:15 p.m. | Ballroom Policy experts will discuss whether the deep divisions in the policies parties over the Affordable Care Act will diminish in the years ahead and whether there can be bipartisan efforts to improve the healthcare system.
