I want to find patients who have been diagnosed with external causes (such as accidents or assaults) with a specific focus on assault-related cases, by analyzing the encounter and patient sets from the specified time periods, and combining them with the previous query results for external causes and assault diagnoses. The specificity scale is set to 0, and the query timing is set to ANY, meaning it will include all available data. The panel accuracy scale is set to 100, indicating high confidence in the results. The query is designed to provide a comprehensive analysis of assault-related cases within the given timeframe.
