Registration is open for December 9 and December 16 webinars to introduce researchers to AHRQ’s Nationwide Readmissions Database (NRD). The resource is part of the Agency’s Healthcare Cost and Utilization Project (HCUP). The December 9 webinar, Overview of the HCUP Nationwide Readmissions Database (NRD), will provide an introduction to the NRD. The second, Utilization of the HCUP Nationwide Readmissions Database (NRD), will educate users on how to produce and explore variances in rates of readmissions. In addition, HCUP has released Nationwide Readmissions Database Tutorial, an online course for researchers to use the NRD to produce national readmissions estimates. The tutorial’s first section, Database Design, provides background on the NRD, its design, its key data elements and its limitations. A second section, Using the NRD, provides sample event criteria to help researchers calculate national estimates of readmission rates using the database. Email HCUP User Supportfor more information.
