Summary of the multivariate logistic regression results* for predicting the use of any PIMs† at discharge

Variables	OR (95% CI)	P values
Age	0.97 (0.96 to 0.97)	0.02
Women	1.70 (1.17 to 2.48)	0.01
Charlson Comorbidity Index	1.03 (0.92 to 1.16)	0.56
Number of medications at admission	1.20 (1.14 to 1.27)	<0.001
Duration of hospital stay	1.00 (1.01 to 1.00)	0.96

*The following variables were used: age, gender, Charlson Comorbidity Index, number of medications at admission and duration of hospital stay.

†PIMs were defined based on the 2015 American Geriatric Society Beers Criteria.
