The Agency for Healthcare Research and Quality has released the Revisit Files, the newest addition to the supplemental files created under HCUP. The Revisit Files are designed to facilitate analyses for tracking patients across time and hospital settings in the HCUP State Inpatient Databases (SID), State Ambulatory Surgery Databases (SASD), and State Emergency Department Databases (SEDD) while adhering to strict privacy guidelines.

The files enhance the value of the HCUP State databases by allowing for a variety of analyses, such as evaluating repeat emergency department use, readmissions to the hospital, admissions to the hospital after ambulatory surgery, or patterns of ED and hospital utilization for chronic conditions.

Currently twelve HCUP Partners have authorized the release of their State Revisit Files through the HCUP Central Distributor. For more information about the HCUP Supplemental Revisit files, please visit the HCUP-US website at http://www.hcup-us.ahrq.gov/toolssoftware/revisit/revisit.jsp.
