“…This has evolved from uniform prescribing recommendations for an amount of opioids based on the surgical procedure done, to prescribing opioids based on inpatient hospital use of pain medications, to calculators like our own which utilize multiple patient factors to more precisely predict a patient’s need for opioids at home ( Boitano et al, 2020 , Glaser et al, 2020 , Michigan Opioid Prescribing Engagement Network, 2020 , Overton et al, 2018 , Rodriguez et al, 2022 , Straubhar et al, 2021 , Straubhar et al, 2023 ). Similarly developed calculators have been published by groups from Duke University and the University of Michigan ( Rodriguez et al, 2022 , Straubhar et al, 2021 , Straubhar et al, 2023 ). Their approaches combine minimally invasive and open surgical patients while we chose to focus on open surgical patients alone as our practice is to give no more than 5 doses of opioids after laparoscopic surgery.…”
