I want to find all instances of inpatient visits within the i2b2 database, regardless of time frame, with a specificity scale of 0, panel accuracy scale of 100, and a single item occurrence. This query will return data on patients who have had an inpatient visit with no inversion applied and will be displayed in the first panel using the LA icon.
