Rate of CVC utilization and CLABSI incidence in different areas of China

Region of China	No. of hospitalization days	No. of device days	No. of patients with CLABSI	Utilization rate of CVCs,% M (Q1, Q2, Q3)	CLABSI rate, per 1000 catheter-days M (Q1, Q2, Q3)	P value
Central China	230,783	87,818	120	38.05 (29.94, 38.29, 54.83)	1.37 (.00, .52, 1.60)
Eastern China	667,988	285,205	462	42.7 (28.47, 45.25, 60.24)	1.62 (.00, 1.00, 2.57)	.0964
Northeast China	64,038	28,522	22	44.54 (36.83, 37.15, 45.09)	.77 (.00, .62, .91)	.0095
Western China	126,113	65,040	98	51.57 (37.13, 63.82, 84.78)	1.51 (.00, .91, 1.73)	.4728

Region of China: according to the situation of China’s economic and social development, the country is divided into four major regions. Northeast China: Liaoning; Central China: Shanxi, Henan, Hunan; Eastern China: Beijing, Jiangsu, Zhejiang, Shandong, Guangdong; Western China: Guizhou, Sichuan

P value: CLABSI incidence of different regions of China were separately compared with Central China. P values < 0.0125(0.05/4 = 0.0125) were considered statistically significant
