Hospital-acquired acute kidney injury: a proposed patient safety indicator.

Patient safety, which includes adverse event reporting and routine collection of outcome measures, has become an increasingly important aspect of inpatient care worldwide. In the United States, the National Quality Forum leads the effort in developing such measures for use in payment and public reporting programs. However, choosing and prioritizing events to serve as patient safety indicators is difficult in a dynamically changing and complex healthcare environment. In this perspective, we propose that hospital-acquired acute kidney injury (HA-AKI), for example, contrast-induced and postoperative AKI, should be added to existing, more traditional measures, such as surgical site infections and patient falls. The article highlights the significance of HA-AKI as a common complication resulting from a multitude of diagnostic and therapeutic procedures, how it lends itself well to measuring patient safety, and how reporting of this complication can contribute to further improvement of patient safety and overall quality of care.
