Parameter	Adjusted hazard ratio (95% confidence interval)	p value
No medical insurance	2.898 (1.303–6.445)	0.009
Chronic alcohol abuse	3.295 (1.559–6.964)	0.002
Chronic pulmonary disease	2.151 (1.027–4.503)	0.042
ICU admission within 24 h of vancomycin initiation	3.327 (1.487–7.446)	0.003
Receipt of Gram-negative coverage	2.812 (1.160–6.817)	0.022
