(a) Order set items with the highest additional a la carte ordering rates, excluding uncommon order sets used fewer than 100 times (these are items that clinicians frequently needed at the time of order set use, but were not included in the order set build), and (b) order set items with the highest a la carte to order set ordering ratios, excluding order sets used fewer than 100 times (these are items included in order sets, but were frequently skipped over by clinicians and instead more likely to instead be ordered a la carte right after order set use)
