AHRQ has specifically stated that a risk assessment scale will be included in its DHHS integration project. The committee believes a risk assessment scale should be included in the common patient safety report format. In addition to an RAI, the committee believes that differentiating between probability and preventability is important to the analysis of events. Therefore, a method for assessing and a taxonomy for representing preventability should also be agreed upon and implemented. For example, if the event in question is a medication error that resulted from a mixup of medi-
