Preexisting opioid daily MME and use duration within a national cohort of lumbar spine surgery patients on quality outcomes

Objective: Pain management surrounding lumbar spine surgery is a complex topic. Though some authors suggest that preoperative opioid use is a negative prognostic factor, its association with patient-reported outcomes and satisfaction after surgery remains controversial. We aimed to uncover the effect of preoperative opioid use on long-term outcomes using a national sample.

Methods: Using deidentified data from the lumbar spine surgery Quality Outcomes Database, we compared functional outcomes and satisfaction in 34,934 patients based on presence of preoperative opioid use. Outcomes included Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and satisfaction indices. Regression subanalysis illustrated the effect of preoperative opioid duration and daily MME.

Results: 44.1 % used opioids preoperatively. A greater percentage of patients using opioids underwent surgery with instrumentation (p < .005). They exhibited clinically comparable improvement in VAS, ODI, and satisfaction at 3- (p = .069, p < .005, p < .005, respectively) and 12-months (p < .05). Return to work was lower at 3- (74.32 % vs. 80.82 %, p < .005) and 12-months (48.99 % vs. 62.95 %, p < .005). They maintained low postoperative use although greater than opioid naïve patients at 3- (3.1 % vs. 1.2 %, p < .005) and 12-months (3.6 % vs. 0.8 %, p < .005). Preoperative daily MME had no significant effect on outcomes, although increasing duration negatively impacted VAS and ODI scores.

Conclusions: Preoperative opioid use by itself should not be used in surgical decision making but rather an individual risk assessment according to chronicity of opioid burden. Longer duration of use appears to impair postoperative improvement but not satisfaction with little influence by daily MME; however, larger, granular analyses remain necessary.
