I want to find patients who have been diagnosed with external causes, such as accidents, poisonings, or other injuries, at any time, using the specified patient and encounter sets from the previous query "External causes@23:38:14" and "External causes@23:37:39", with a specificity scale of 0 and an accuracy scale of 100, and without considering synonyms.
