Safety of maintaining intravenous sites for longer than 48 H
Abstract:
Two years of experience with infections in intravenous (IV) therapy were studied through cohort analysis of infection surveillance records. The overall rate of infection was low compared with other published reports, but the risk of infection was related to the duration of cannulation. IVs in place for no more than 48 h accounted for 75% of all IVs and 26% of IV-associated infections, those in place for 48 to 72 h accounted for 12.5% of IVs and 23% of IV-associated infections, and those in place in excess of 72 h accounted for 12.5% of IVs, but 51% of IV-associated infections. Septicemia was associated with site infection in 20% of cases. This application of routinely obtained infection surveillance data demonstrates the ability of comprehensive surveillance programs to facilitate administrative decisions and to document subsequent quality of patient care.
Insights
Intravenous (IV) therapy infections are linked to how long catheters remain in place. Prolonged IV cannulation, especially over 72 hours, significantly increases infection risk and septicemia, highlighting the need for effective surveillance.
Area of Science:
- Infection Control
- Healthcare Quality Improvement
- Epidemiology
Background:
- Intravenous (IV) therapy is a common medical procedure.
- Catheter-associated infections pose a significant risk to patient safety.
- Understanding infection risk factors is crucial for improving patient care.
Purpose of the Study:
- To analyze infection rates associated with intravenous (IV) therapy.
- To determine the relationship between the duration of IV cannulation and infection risk.
- To evaluate the utility of infection surveillance data for quality improvement.
Main Methods:
- Cohort analysis of infection surveillance records over two years.
- Categorization of IVs based on duration of cannulation (≤48h, 48-72h, >72h).
- Calculation of infection rates and proportions of infections by duration.
Main Results:
- Overall IV infection rate was low compared to published data.
- Infection risk increased significantly with longer duration of cannulation.
- IVs in place >72 hours accounted for 51% of infections despite being only 12.5% of all IVs.
- Septicemia was linked to site infection in 20% of cases.
Conclusions:
- The duration of IV cannulation is a critical factor in infection risk.
- Extended IV dwell times are disproportionately associated with higher infection rates.
- Comprehensive infection surveillance systems can inform administrative decisions and enhance patient care quality.
