Current rates of opioid prescribing have deleterious consequences on both patient and societal levels. This study aims to evaluate responsible opioid prescribing and predictors of opioid consumption in immediate implant-based breast reconstruction.
Patients undergoing consultation for immediate, implant-based breast reconstruction were enrolled in a prospective, cohort survey study. A survey was administered at the preoperative and postoperative appointment to collect data on pain expectations and opioid use. A medical record review was performed.
Of 100 enrolled patients, 97 (97.0 percent) underwent surgery and 85 (85.0 percent) completed the postoperative survey. Preoperatively, 27 patients (27.0 percent) had a history of a chronic pain syndrome, 34 (34.0 percent) had a history of a mental health comorbidity, and nine (9.0 percent) had a history of active preoperative opioid use. A total of 85 tissue expander (87.6 percent) and 12 direct-to-implant (12.4 percent) reconstructions were completed. Patients were prescribed an average of 36.0 5-mg oxycodone tablets postoperatively. Patients reported consuming an average of 20.6 tablets, or 57.0 percent of the average prescription amount. The majority of patients (75.3 percent) reported taking an opioid less than once per day at the time of survey completion, and 24 patients (28.2 percent) reported that they did not use any opioids postoperatively. Preoperative opioid use (p = 0.004), inpatient opioid consumption (p < 0.0001), and patient-reported anxiety related to pain control (p < 0.05) were predictors of opioid consumption.
Patients undergoing mastectomy and implant-based breast reconstruction are prescribed nearly twice as many opioid tablets as consumed, and one in three patients report not using any opioids postoperatively. Clinical factors may help guide prescribing practices.
