[Green intensive care unit].

The "Green Intensive Care Unit" addresses the challenge of reducing the ecological footprint of the healthcare sector, which is responsible for 4.4% of greenhouse gas emissions worldwide. In Germany, the healthcare sector accounts for 5.2% of national emissions. Intensive care units in particular are resource-intensive due to their high energy consumption, waste generation and the use of disposable materials. Sustainability in intensive care medicine aims to combine ecological responsibility with excellent patient care. This includes the introduction of overarching sustainability strategies, greater digitalization and the efficient use of resources. Energy-efficient equipment, improved waste management systems and the targeted optimization of processes reduce the consumption of resources. Conscious handling of medicines, appropriate use of protective materials and the use of sustainable materials also help to minimize the ecological footprint. In addition, the promotion of palliative care and advanced care planning makes it possible to avoid overuse while ensuring the quality of patient care. These approaches are based on a current S1 guideline (by the DGIIN) and offer practicable solutions to promote sustainability in intensive care medicine without compromising on care. Successful implementation requires a deep awareness of sustainable action and close integration with higher-level healthcare structures.
