I want to find any instances where a patient has taken insulin, as indicated by the keyword "Taking Insulin" in the medical record, with a specificity scale of 0, meaning the search is not restricted to any particular context, and an accuracy scale of 100, indicating a high level of confidence in the search results. The query should include only one panel with the panel timing set to "ANY," meaning the search is not limited to a specific time frame, and the panel's invert option is set to 0, meaning the search will return records where the keyword appears. The query will search for the exact phrase "Taking Insulin" and will not consider synonyms.
