Abstract
Purpose:
Medical waste contributes to health care costs and has a direct negative impact on the environment. The goals of this study are to quantify and categorize the medical waste generated by intravitreal injection procedures and identify opportunities to reduce waste.
Methods:
This is a prospective observational series. Medical waste from intravitreal injections was collected from 337 consecutive intravitreal injections by a retina specialist over 2 weeks. The waste was sorted, photographed, weighed, and recorded.
Results:
A total of 65.6 kg of waste was collected across 3 broad categories: (1) shipping waste (cardboard boxes, foam coolers, cold packs, and bubble wrap); (2) waste from administering the intravitreal injection (nitrile gloves, tissues, wipes, and plastic or paper packaging); and (3) biohazard waste (used syringes and needles). Shipping waste contributed 83% of the overall waste, by mass, and varied greatly based on the size of the order and how efficiently shipments were packed. Cold packs, foam coolers, cardboard/paper, and nitrile gloves were the greatest contributors to carbon emissions and landfill.
Conclusions:
Waste due to shipping of medication is a major opportunity for reducing the environmental impact of intravitreal injections. Buying in bulk is a simple way for retina practices to reduce waste. Manufacturers should consider less bulky packaging for branded intravitreal injections; distributors and outsourcing facilities should consider take-back programs to reuse coolers and cold packs. Improved sustainability in the treatment of retinal disease is achievable but requires awareness and optimization of a clinic’s routine.
