I want to find the length of stay for any patient visit with a specificity scale of 0 and an accuracy scale of 100, where the query timing is set to ANY and the panel timing is also ANY, and the item is located under the Visit Details section with the key \i2b2_VISIT\i2b2\Visit Details\Length of stay\.
