A randomized controlled noninferiority trial of reduced vs routine opioid prescription after prolapse repair

Given the accelerating opioid crisis in the United States and evidence that patients use fewer opioid tablets than prescribed, surgeons may choose to decrease prescribed quantities. The effect this may have on patient satisfaction with pain control after hospital discharge is unknown. The primary objective of this study was to compare patient satisfaction with postoperative pain control between patients receiving a routine or reduced quantity opioid prescription after prolapse repair. Secondary objectives included a comparison of opioid-related side-effects, the number of opioid tablets used, and the number of excess tablets prescribed between these groups. This was a single-center, unmasked, 2-arm, randomized controlled noninferiority trial of women who underwent a prolapse repair with a planned overnight hospitalization. Patients were assigned randomly to 1 of 2 study arms: routine (28 tablets of oxycodone 5 mg) or reduced (5 tablets) prescription of opioid tablets. Patients were eligible if they were at least 18 years of age and undergoing a prolapse repair with an anticipated overnight hospital stay. Exclusion criteria included a history of chronic pain, preoperative opioid use, intolerance to study medication, or a score of ≥30 on the Pain Catastrophizing Scale. In addition to their opioid prescription, all patients received multimodal pain medications at discharge. Patients were asked to complete 6 weeks of diaries to record pain and medication use. The primary outcome (patient satisfaction) was collected as part of a postoperative survey completed at patients’ routine postoperative visit 6 weeks after surgery. The sample size for noninferiority was calculated at 59 patients per group for a total of 118 patients. One hundred eighteen patients were assigned randomly; the primary outcome was available for 116. The majority of patients were white, postmenopausal, and nonsmokers; the mean age was 62±10.4 years. The most common surgery was a hysterectomy with native tissue repair (n=71; 60%). One hundred ten patients (93%) were satisfied with postoperative pain control. Statistical analysis constructed for noninferiority showed that the difference between the groups was
