Climate Change in Medicine (Murphy, 4/24/2024)

Thanks so much for a wonderful Grand Rounds this week -- a somber and thought provoking and hopeful presentation-- from SRFMR Alumnus Dr. Sarah Murphy on Climate Change in Medicine. A recording of the presentation can be found HERE. 

My notes:

Dr. Murphy began her presentation with the concept of Planetary Health and the question What if the planet were our patient? As family doctors, we can definitely all understand this question because anyone, really anyone, can be our patient, and the interconnectedness of the health of families and communities and our world are central to the work we do every day. 

Consider these thought-provoking statements about the relationship between human health, our planet's health, and health professionals' role:

• “Human health and the health of our planet are inextricably linked, and our civilization depends on human health, flourishing natural systems, and the wise stewardship of natural resources.” (2015 Rockefeller Foundation-Lancet Commission on Planetary Health)
• “Health professionals have an essential role in the achievement of planetary health: working across sectors to integrate policies that advance health and environmental sustainability, tackling health inequities, reducing the environmental impacts of health systems, and increasing the resilience of health systems and populations to environmental change.”

Climate change in 10 words, From Yale Program on Climate Change

Scientists agree.

It's real.

It's us.

It's bad.

. . . There's hope.

Climate change has a direct impact on human health across many different domains. Here are just a few concrete examples:

1. Extreme heat>>dehydration, heat stress (particularly children, elders), MI/CVA, altered mental status, food insecurity, higher food costs, etc.
2. Outdoor air quality>>smoke, high pollen counts, short and long-term health effects (including small and large particles that can cause acute disease, but also smaller particles that cross alveoli and can lead to long-term impacts on IQ, heart disease, obesity, etc. And then there's indoor air quality. . .
3. Flooding>>rising sea levels, more intense precipitation, hurricanes, leading to displacement, water-borne diseases, drowning, etc.
4. Vector born infection>>rising temperatures change the range of vectors, increasing Lyme disease distribution, mosquito-born illness (e.g. dengue) and increasing risk particularly for children, who are outside playing close to the earth often at dawn and dusk
5. Food born infection>> toxic algae blooms, increase rates of campylobacter, cholera crypto. Increased diarrheal disease
6. Mental health. Dr. Murphy introduced the idea of "eco-anxiety" or "eco-grief" that has three components: 1) acute or past physical ecological loss, 2) the loss of environmental knowledge and 3) anticipated future loss.

Ecological grief and anxiety

What kind of ecological grief do you see around you? What kind of climate change (aka eco-anxiety) do you personally experience or see in your clinical practice? How do we support patients in dealing with this kind of grief?

Participants at Grand Rounds shared their own grief and anxiety after the 2017 Tubb's wildfire, concerns about family lands destroyed by flooding in India, loss of salmon runs in Alaska. And more. We all have stories.

Graphic from paper: Ecological grief and anxiety: the start of a healthy response to climate change?

Dr. Murphy urged us rather than think about these responses as pathological, perhaps we reframe them as reasonable and functional responses. The key is what do we do with these feelings? Do we acknowledge them in ourselves? Do we ask patients about them? Do we have outlets to build community and affect change driving by the need to respond to these emotions? 

Climate change, health disparities and inequities

Unsurprising to those of us who practice in the safety net, there is intersection between social determinants of health and social vulnerability. Our most vulnerable populations suffer the greatest health impacts of climate change. 

For more information, check out the CDC+UCSF Pediatric Environmental Toolkit available at:  https://www.atsdr.cdc.gov/emes/health_professionals/pediatrics.html

There is a subset of the toolkit that focuses on environmental exposures linked to climate change and gives providers key information and good tips on anticipatory guidance in well-child checks

The healthcare system's direct impact on Planetary Health Don't forget that the healthcare industry, in general, and hospitals, specifically, contribute a tremendous amount of waste and greenhouse gases that only compound climate change. 8.5% of US total waste is healthcare sector waste. If healthcare were our own nation, we would rank 13th in greenhouse gas emissions. This also doesn't take into account supply chain waste, single use waste, water and sanitation issues.

And yet, even still there is hope.

Hope you say?

Yes.

Yet among this crisis we have an opportunity: Our best science tells us that the The severity of climate-related health risks is highly dependent on how well health systems can protect people.

With timely, proactive and effective adaptation many risks for human health and wellbeing can be reduced and some potentially avoided (very high confidence) 

Read this article from UW: Hope Health and the Climate Crisis (Frumkin, 2022). Frumkin tells s that hopeful people feel better, hope leads to action, and hope is empirically justified.

What can healthcare providers do?

• We can vote with our wallet (spend money where it matters and buy things that are good for the planet)
• OR Buy LESS (se second hand, repurporse)
• Talk with patients about the health impact, their actions, and their eco-grief
• Enjoy the outdoors -- having a relationship with our planet will help us protect our planet
• Join a group that is doing advocacy

Take the examples of Dr. Plastic Picker (a Kaiser pediatrician in southern CA who is modeling beach cleanup and climate change action), Climate Health Now (Drs. McLure and Millstein, CA advocacy group) or anesthesiologists who are advocating to decresae their use of gases.
