ABSTRACT
Objective To investigate the usage of intravenous infusion and the antibiotic intravenous infusion in different hospitals nationwide ,and to evaluate the influence of the hospital bed number ,hospital area and hospital grade on the clinical application of intravenous infusion .Methods Intravenous infusion volume ,rate and other related indexes were analyzed based on the inpatient information obtained from the regional medical big data net for 156 hospitals .Results 1323852 inpatients were included in this study .93 .13％ of those patients received intravenous infusion therapy .The average daily infusion volume was 782 .67 ml per bed .The average infusion time was 7 .39 days per patient .44 .78％ of inpatients received intravenous antibi-otic treatment .The average daily antibiotic infusion volume was 92 .48 ml per bed .Conclusion Generally ,the inpatient per-centage of intravenous infusion was getting higher in China .The greater infusion volume in larger hospitals suggested that the patient′s condition is relatively more serious in the larger hospital .The higher grade hospitals used smaller antibiotic infusion rate and volume ,indicating the antibiotic use in high grade hospitals is relatively more standardized .
