Neurointerventions Face Waste Audit

Investigators quantify procedural waste, disposal costs, and carbon emissions in a neurointerventional angiography suite.

1

Neurointerventional procedures produced an average of 6.7 kg of solid waste per case, with clinical waste comprising over half of this total.
2

Aneurysm procedures generated the highest average waste volume at 8.9 kg per procedure, while diagnostic cerebral angiography produced the least at 5.2 kg.
3

Recyclable materials accounted for a significant portion of the waste, with recyclable plastic averaging 1.4 kg and paper 0.9 kg per procedure.
4

The average waste disposal cost was estimated at $1.56 per procedure, varying from $1.20 for diagnostic angiography to $1.92 for aneurysm embolization.
5

The study highlighted the need for targeted waste-reduction strategies due to variability in waste generation and disposal costs across different procedures.
