Summary of opioid consumption and weaning rates.
| Measures | Opioid naïve |
Opioid experienced |
|---|---|---|
| (n = 110) † | (n = 137)a | |
| Mean MEQ (mg) consumed (mean ± SD) | ||
| Presurgical | 0 | 78.8 (100.2) |
| Hospital discharge (postsurgical) | 106.7 (80.6) | 140.5 (124.0) |
| Final TPS visit | 37.3 (61.1) | 78.3 (113.9) |
| % Decreased from discharge | 69.4% | 44.3% |
| Weaning rate achievedb | ||
| No longer taking an opioid (100%) | 49 (44.5%) | 35 (25.6%) |
| Reduced to ≥50% | 39 (35.5%) | 48 (35.0%) |
| Reduced to <50% | 11 (10.0%) | 28 (20.4%) |
| Increased from hospital discharge | 11 (10.0%) | 26 (19.0%) |
aTwo outliers from each group, with a standardized residual change score of greater than four, were removed for a total of four outliers.
bWeaning rates are measured from hospital discharge to a mean time of 6 months.
MEQ = morphine equivalents; TPS = Transitional Pain Service.
