Study Of Related Factors Affecting Standardization Of Intravenous Administration Time

Objective:Through investigated questionnaires to nurses of tertiary hospital that could explore the affecting factors of clinical intravenous dosing time condition and analysis intravenous dosing time, dosing speed and interval dosing time. Then provided evidences for clinical managers to make relate measures and improved the safety to clinic intravenous dosing time.Methods:Designed questionnaire of intravenous dosing time of nurse cognitive condition and tested it’s validity. Then selected the nursers of three units of internal, surgery and ICU to did questionnaires. Designed table of Intravenous check dosing time of nurse condition,which included three aspects dosing time,dosing speed and interval dosing time. According to the table to traced the condition of intravenous patients. Collected those data and statistics intravenous dosing time of nurse cognitive condition of intravenous dosing time of nurse condition respectively by descriptive analysis. Binary and logistic regression was used to determined the affecting reasons of intravenous start dosing time, intravenous interval dosing time and intravenous dosing speed. All the data was analyzed with the statistic package for social science (SPSS)17.0.Results:1. From the results of intravenous dosing time of nurse cognitive condition showed that the option of most part of cognitive level of nurses was87.15%and five of them was less than85%. The post-anesthetic care unit showed the highest score and emergency care unit was lowest on the item of realize damage of the interval of intravenous dosing time. The post-anesthetic care unit showed the highest score and respirate unit showed lowest on the item of using tee.The post-anesthetic care unit showed the highest score and respirate unit was lowest on the item of adjust the intravenous speed on the item of doctor’s advice dosing speed. The post-anesthetic care unit showed the highest score and hepatopancreatobiliary surgery unit was lowest on the item of offering intravenous related education to patients. The post-anesthetic care unit showed the highest score and respirate unit was lowest on the item of adjust the intravenous speed on the item of doubt the doctor’s advice dosing speed.2. We collected556cases clinic intravenous infusion data. For the aspect of intravenous infusion dosing time,499(89.7%) were standard and non-standard were57(10.3%) in all556traced cases. As to the aspect of intravenous infusion dosing speed,361(64.6%) were standard and195(35.4%) were non-standard. For the aspect of interval dosing time, BID was5.47±1.25h,Q8H was6.37±2.81h, Q12H was9.84±1.54h and Q6H was4.86±3.03h.The interval dosing time,25(46.3%) were standard non-standard were29(53.7%) in54traced cases.3.Different.unitsof.intravenous.dosing.time.showed.statistical.significance,p=0.000Emergency care unit was.highest.standard. rate.which.was.97.5%.and neurology unit is the lowest standard rate which was76.4%.The intravenous nurser’s length of service showed statistical significance on the aspect of intravenous dosing time, p=0.040.And nurser’s length of service between11-15years is the highest rate on the intravenous dosing time occupied97.4%.Different.units.of.intravenous. interval dosing.time.showed statistical.significance,p=0.000.Neurology unit was.highest.standard.rate.which.was.98.2%and respirate unit is the lowest standard level which was40.9%.4. Single factors analysis showed that infusion needle types and single intravenous infusion liquid milliliter were significant on non-standard intravenous infusion dosing speed.5. Binary multiple factors regression analysis showed that PICC and CVC of infusion needle types and single intravenous infusion liquid milliliter were the main factors on non-standard infusion dosing speed.Conclusion:1. The overall cognitive condition showed higher level and post-anesthetic care unit showed the highest score on the clinic intravenous dosing time of questionnaire.2. Clinic trace invested showed that rate of non-standard intravenous dosing speed was higher than strat dosing time, but interval dosing time was the lowest.3. On the aspect of dosing time emergency care unit was highest standard rate and neurology unit was the lowest standard rate. It was worth mentioning that nurser’s length of service between11-15years is the highest standard rate on dosing time.On the aspect of dosingspeed neurology unit was highest standard rate and respirate unit was the lowest standard rate. 4. PICC and CVC of infusion needle types and intravenous infusion liquid milliliter were the main factors relate to non-standard infusion dosing speed.
