Deadline: April 1, 2016 For the first time, the workshop will feature poster sessions. The program committee is seeking abstracts highlighting current, relevent research in the areas of regulatory and industry statistics. Please click here on how to submit your abstract.
Statistical Methods in Economic Evaluations Workshop May 2, 2016
Statistical Methods in Economic Evaluations Workshop May 2, 2016 — Renaissance Arlington Capital View Hotel, Arlington, VA 2800 South Potomac Ave, Arlington, VA, 22202, (703) 413-1300 Economic evaluations play an integral role in informing health care policy decisions. These studies often rely on data from clinical trials, prospective registries, and secondary data. The availability of patient-level data allows analysts to apply conventional and innovative statistical methods to patient-level data. Using examples, the faculty will examine statistical approaches that address common features of resource use and cost data, including distributional characteristics, censoring, hierarchical data structures, and potential confounding. Additional statistical issues that arise when combining patient-level estimates of costs and effectiveness will also be discussed.
This workshop is considered "Day 0" to the 9th Annual FDA/AdvaMed Medical Devices and Diagnostics Statistical Issues Conference. Professionals often attend both the workshop and the conference. The conference will be held the day after the workshop. To register, go to here.

New FDA National Medical Device Evaluation Plan
On behalf of the American Statistical Association (ASA) Section on Medical Devices and Diagnostics (MDD), Greg Pappas wrote an article on the new FDA National Medical Device Evaluation Plan (attached). It was published in the December 2015 issue of the Amstat News (2nd attachment), a monthly publication that every member of the ASA receives. The article is great visibility for the FDA National Medical Device Plan and the MDD ASA Section. The article is available here.
