The study reported by Dr. Mark ran after the Roswell Park gynecologic oncology department implemented new guidelines for dispensing pain control medications following surgery. The guidelines called for comprehensive teaching for patients about pain expectations and pain management both before and after surgery and also established four dispensing categories:
- Patients undergoing minimally invasive or outpatient surgery and with no history of chronic pain and low opioid need while hospitalized received the default dispense of 600 mg ibuprofen every 6 hours as needed for 7 days and 500 mg acetaminophen every 6 hours as needed for 7 days.
- Patients who underwent this surgery but required 5 or more opioid tablets while hospitalized or those with a history of chronic pain and opioid use received the ibuprofen and acetaminophen regimen plus 12 opioid tablets, a 3-day supply with 1 tablet taken every 6 hours as needed.
- Patients who underwent laparotomy and had no chronic pain and opioid history and low opioid use while hospitalized received the ibuprofen and acetaminophen regimen plus 12 opioid tablets, a 3-day supply.
- Patients who underwent laparotomy and showed a higher opioid need based on their use during the 24 hours before discharge received the ibuprofen and acetaminophen regimen plus 24 opioid tablets for 3 days so they could take 2 tablets every 6 hours as needed.
Dr. Mark and his associates collected data from 337 patients managed with these guidelines during June 2017–January 2018 and compared them with 626 patients who underwent gynecologic surgery at Roswell Park during July 2016–June 2017. The data showed the average number of opioid tablets dispensed per patient for all discharges fell from 31.7 before the new guideline to 3.5, an 89% reduction. For the subgroup of patients who had undergone a laparotomy, the average pill number fell from 43.6 to 11.6, a 72% drop. Among patients treated with minimally invasive or outpatient surgery, average tablets dispensed fell from 28.1 before to 0.9 after, a 97% reduction. The reduction among opioid-naive patients was 90%, and it was 83% among patients who used opioids prior to their surgery.
