Balancing Patients' Eating Habits with Planetary Health-Pilot Study to Decrease Food Waste with Vegetarian Lunches using a Quality Improvement Approach.

Background: Patient health is greatly impacted by increased likelihood of malnutrition if food is not consumed. Food waste also contributes to greenhouse gas emissions and may be possibly reduced by offering vegetarian food options. Therefore, a Plan-Do-Study-Act intervention of "Vegetarian Week" was conducted in an urban geriatric rehabilitation unit.
