Howard R, et al. - In this population-based study of patients undergoing surgery in Michigan, researchers described opioid prescribing and consumption for a variety of surgical procedures and determined factors related to opioid consumption after surgery. Using a sample of adults 18 years and older undergoing surgery, they included patients if they were prescribed an opioid after surgery. Surgical procedures were carried out in at least 25 patients between January 1, 2017, and September 30, 2017. The prescription size was most strongly associated with opioid use after surgery, with patients using an additional 5 pills for every 10 additional pills prescribed. History of tobacco use, American Society of Anesthesiologists class, age, procedure type, and inpatient surgery status were included other significant risk factors. They observed that the quantity of opioid prescribed was related to higher patient-reported opioid consumption. The use of patient-reported opioid consumption to improve prescription practices is an important step in the fight against the opioid epidemic.
