Appropriate Opioid Use After Spine Surgery: Psychobehavioral Barriers and Patient Knowledge.

Objective: To identify spine patients' barriers to appropriate postoperative opioid use, comfort with naloxone, knowledge of safe opioid disposal practices, and associated factors.
Methods: We preoperatively surveyed 174 spine patients about psychobehavioral barriers to appropriate opioid use, comfort with naloxone, and knowledge about opioid disposal. Multivariable logistic regression identified factors associated with barriers and knowledge (α = 0.05).
Results: Common barriers were fear of addiction (71%) and concern about disease progression (43%). Most patients (78%) had neutral/low confidence in the ability of nonopioid medications to control pain; most (57%) felt neutral or uncomfortable with using naloxone; and most (86%) were familiar with safe disposal. Anxiety was associated with fear of distracting the physician (adjusted odds ratio [aOR], 3.8; 95% confidence interval [CI], 1.1-14) and with lower odds of knowing safe disposal methods (aOR, 0.18; 95% CI, 0.04-0.72). Opioid use during the preceding month was associated with comfort with naloxone (aOR, 4.9; 95% CI, 2.1-12). Patients with a higher educational level had lower odds of reporting fear of distracting the physician (aOR, 0.30; 95% CI, 0.09-0.97), and those with previous postoperative opioid use had lower odds of concern about disease progression (aOR, 0.25; 95% CI, 0.09-0.63) and with a belief in tolerating pain (aOR, 0.34; 95% CI, 0.12-0.95).
Conclusions: Many spine patients report barriers to appropriate postoperative opioid use and are neutral or uncomfortable with naloxone. Some are unfamiliar with safe disposal. Associated factors include anxiety, lack of recent opioid use, and no previous postoperative use.
