Reducing the Climate Impact of Critical Care

Area of Science:

• Environmental Science
• Critical Care Medicine
• Public Health

Background:

• Climate change poses significant health risks, necessitating action from healthcare professionals.
• The environmental impact of healthcare delivery, particularly in intensive care units (ICUs), is a growing concern.
• While clinicians manage climate-related illnesses, their role in mitigating healthcare's climate footprint is less understood.

Purpose of the Study:

• To explore the primary drivers of the intensive care unit (ICU) climate footprint.
• To identify and present potential solutions for reducing the environmental impact of critical care.
• To emphasize the role of critical care clinicians in advocating for environmental policy and healthcare decarbonization.

Main Methods:

• Case-based review of ICU climate footprint drivers.
• Analysis of energy consumption, supply chain, pharmaceutical emissions, plastic waste, and low-value care.
• Exploration of multidisciplinary team engagement and policy advocacy.

Main Results:

• Key drivers of the ICU climate footprint include high energy use, supply chain, pharmaceutical emissions, plastic waste, and low-value care.
• Multidisciplinary engagement is crucial for implementing effective solutions.
• Critical care clinicians can play a vital role in advocating for environmental policy.

Conclusions:

• Critical care providers have a responsibility to minimize the environmental impact of healthcare.
• Addressing the ICU climate footprint requires a multifaceted approach involving energy efficiency, supply chain management, and waste reduction.
• Clinicians are well-positioned to lead health care decarbonization efforts and advocate for policy change.
