Objective To investigate the status quo of implementation ofIntravenous Practice Standard in a tertiary A hospital in Sichuan. Methods At 09:00-11:30 am, on March 16th, 2016, a questionnaire designed by intravenous team (IV Team) was used to conduct the investigation in all the inpatiets according to inclusion and exclusion criteria. The SPSS 17.0 software was used to perform all statistical analysis. Results The intravenous infusion rate in the hospital was 76.87%, while the rate in Emergency Department peaked up to 96.11%. Indwelling needle was the most common used device for intravenous therapy in clinical practice, which was used in 77.91% of the inpatients, and steel needle, peripherally inserted central catheter (PICC), central venous catheter, and implantable venous access port were also widely used. Peripheral intravenous catheter was used in 2 990 inpatients, and 78.12% of the puncture sites met the standard; PICC was used in 397 inpatients, and 90.17% of the puncture sites met the standard. The incidence of intravenous infusion related-complications was 15.08%, the incidence of drug exosmosis / exudation was 10.06%, and the incidence of catheter-related blood stream infection (CRBSI) was 2.89%. Conclusions On the whole, the intravenous infusion rate in this hospital accords with the national average level, but the rate in some departments should be controlled. The selection of device for intravenous therapy is reasonable, but the selection of intravenous site should be more standardized. The incidence of intravenous infusion related-complications is low, but the prevention and control of drug exosmosis / exudation and CRBSI should be reinforced. Health care organizations should pay more attention to enforce the Intravenous Practice Standard into practice to promote clinical medical service.
