TDM situation according the American and Chinese consensuses

	P received TDM (n)	TDM rate (%)	P required TDM (n)	TDM R of reaching consensus (%)	Inadequate TDM R (%)	Correct TDM time (n)	R of correct TDM (%)
America	210	32.5	634	33.1	66.9	25	3.9
China	210	32.5	647	32.5	67.5	53	8.2

Correct TDM time: American consensus for TDM: Trough samples should be obtained just before the fourth dose in patients with normal renal function, to ensure that target concentrations are attained. TDM Chinese consensus: Trough samples should be obtained just before the third dose of VAN therapy or before the fourth dose of VAN therapy. P, patients; R, rate; TDM, therapeutic drug monitoring; VAN, vancomycin
