Hospital systems that can facilitate communication by flagging abnormal results and automatically paging or e-mailing ordering physicians about results (as well as documenting acknowledgment of this communication) could be helpful. For laboratory test results, normal or abnormal results can be identified reasonably easily (given that these are numerical values). Studies have demonstrated that physicians respond sooner when prompted by automatic notification of critical laboratory test results (23). However, automatic notification about other tests, such as abnormal radiology results, is challenging for several reasons. First, radiology results are often dictated as text notes that are not classified as normal or abnormal in any kind of coded way. Therefore, it is difficult for a computer algorithm to identify abnormal results. Second, many radiology results require follow-up by several providers (for example, specialist and primary care physician), so identifying who should receive the abnormal report can be problematic. Third, the issue of re-reads complicates matters further. A radiology test can initially be read as normal by a resident but later be read as abnormal by the attending radiologist. Systems must be able to detect these changes to allow for notification that a report has been altered. Work is currently under way to create radiology systems that can manage these issues in a more sophisticated way, and research must be done to demonstrate the benefits.
