Table 3:

Multivariable logistic model for using ≥10 opioid pills vs. 0-10 pills (n=87)

Characteristic	Odds Ratio (95% CI)	P-value
Age (years)	0.98 (0.94 – 1.01)	0.21
Male Gender (vs Female)	0.91 (0.19 – 4.32)	0.91
Charlson Score
1^st quartile (0 points)	Ref	Ref
2^nd quartile (1–2 points)	0.17 (0.02 – 1.62)	0.13
3^rd quartile (3–4 points)	0.40 (0.04 – 3.97)	0.43
4^th quartile (5–11 points)	6.62 (1.60 – 27.50)	0.01^*

Significant at p<0.05

Model p<0.001; Pseudo-R² = 0.24

Variables tested in the model but not included to limit variables or because not significant: Race-ethnicity, received opioid prescription at discharge, elapsed time between surgery and survey, type of surgery, length of admission, prior use of opioids.

Variables with p>0.25 in univariate analysis and therefore not tested in the model: body mass index, central neck dissection, diagnosis of secondary hyperparathyroidism, history of chronic pain disorder, substance use, psychiatric illness or medication, prescription of a non-opioid analgesic, insurance status.
