Reducing omeprazole suspension prescriptions

Hi all, we are looking to reduce prescriptions of omeprazole suspension (powder for suspension) in paediatric inpatients (+/- outpatients) in Newcastle - major cost savings, but also likely environmental/social/?bioavailability reasons.. I'm trying to carbon footrpint the different formulations. My colleague has created a computerised order set as well as a decision tree to help prescribers select the most appropriate formulation based on swallowing abilities, and highlighting the benefits of tablets/capsules where appropriate. Just wondering if anyone else is/has done anything similar?
