24-hour Oral Morphine Equivalent Based Opioid Prescribing After Surgery

The investigators will utilize the electronic health record to individualize pain therapy in surgical patients after hospital discharge using last 24-hour opioid intake as the decision variable for the amount of opioid pain pills prescribed. The preliminary data indicate that current opioid prescription practice after surgery follows a "one size fits all" pattern. In-hospital opioid use 24 hours prior to discharge serves as a strong indicator to correctly estimate needs for analgesic medications at home. The investigators will test the hypothesis that this prescription estimation tool will enable providers to write need-based prescriptions based on each patient's' 24-hour prior-to-discharge opioid use. The investigators will test this tool prospectively for patients after Cesarean section who are anticipated to use about half or less of the usually prescribed amount of opioid pain pills after discharge randomized equally to prescription tool intervention or no intervention (prescription as usual).
