Sustainability interventions in nursing wards
Nursing practice
Replacing IV lines every seven days
IV lines, the part of the infusion system that remains outside the body and connects to the intravenous catheter, are currently replaced every four days to prevent infections. Research shows that replacing IV systems every seven days does not increase the risk of infection. This saves materials and time for nurses.
Intervention
Reduce the frequency of changing infusion lines from once every four days to once every seven days.
Exclusion: Lines used to administer total parenteral nutrition (TPV), blood, propofol and cytostatics are excluded from this intervention due to other guidelines.
Implementation approach
Look at the approach for implementing a different method in nursing practice and consult the step-by-step guide for more information on setting goals, implementation, and evaluation.

Environmental impact
Measured in CO2-emissions by reducing the number of infusion lines. Want to know more about the environmental impact? See the bottom of this page for more information.
Current situation
Change 1 infusion line every 4 days = 0.10 kg CO2-eq
New situation
Change 1 infusion line every 7 days = 0.06 kg CO2-eq
-40% CO2

The environmental impact of an infusion line that is used for 7 days is approximately one and a half times lower than an infusion line that is used for 4 days.
Changing an infusion line every 7 days instead of 4 days with 100 patients for one year saves
600
kg CO2-eq
and is equivalent to driving 3,088 km
When is it implemented?
This intervention is considered implemented when the IV lines in the hospital's nursing units are replaced every seven days and the difference in CO₂-equivalent (kg) has been calculated.
How is this measured?
The environmental impact of this intervention can be determined using the purchasing data of the number of IV lines, see the procedure for measuring an intervention using purchasing data.
Note: Other interventions may affect the results of this one. If the "Using a single IV system across all departments" intervention is implemented at the same time, it may affect the purchasing data for IV lines. Implement the "Use the same infusion system on all units" intervention at a different time to measure the effect accurately.

Reusable non-sterile suture removal set
Sutures can be removed with sterile disposable materials such as gauze, cotton swabs, tweezers, and scissors or a stitch cutter. The tweezers and scissors do not need to be sterile and can be replaced by clean, reusable ones that are cleaned and disinfected. This means the final sterilisation step is omitted after cleaning and disinfection. Mechanical cleaning (thermal disinfection) is preferred over manual cleaning.
Nursing practice
Containers made from recycled plastic for specific hospital waste
Nursing wards produce a lot of waste, including specific hospital waste (SZA). Nurses collect this waste in separate SZA tanks, also known as Wiva barrels, recognisable by the blue barrel with a yellow lid. A more sustainable alternative made from recycled plastic, recognisable by its grey colour, has been developed.
