Three Cornerstone Interventions
Interventions fall into three main buckets, Matsui said: mitigation, adaption, and resilience.
“Mitigation means reducing greenhouse gas and air pollution production and trying to enhance sinks for greenhouse gases,” she said. Mitigation strategies primarily occur at the policy level, with improved regulation, treaties, and market-based approaches, such as carbon tax and cap and trade.
Adaptation includes actions that lessen the impact on health and environment, such as infrastructure changes and implementation of air conditioning. Examples of climate change adaptation strategies also mostly come from policy but largely at state and local levels, where individual pediatricians have a greater voice and influence. These can include changes in urban planning to address heat islands, flooding risk, and public transportation’s contribution to air pollution and climate change. It can also include changes in housing regulation and policy and investments in healthcare, such as expanded Medicaid and health insurance and investing in disaster planning and readiness.
“Resilience is a more holistic concept,” Matsui said, “which advocates for system-wide, multilevel changes and involves a range of strategies to enhance social, human, natural, physical, and financial capacities.”
What Pediatricians Can Do
Pediatricians have an important role to play when it comes to climate change and health impacts.
“The first step is sort of understanding the complexity of climate change in terms of its potential health effects, but also being prepared to talk with our patients and their families about it,” Matsui said. “The second step is advocacy.” She drew attention to the February policy statement in Pediatrics that discusses precisely the ways in which pediatricians can leverage their expertise and credibility.
“Pediatricians are ideal advocates with whom to partner and uplift youth and community voices working to advance zero-carbon energy policy and climate justice,” she said. “There are many opportunities to advocate for climate solution policies at the local, state, national, and even international level.”
These roles can include educating elected officials and health insurance entities about the risks that climate change poses to allergies, asthma, and child health more broadly, as well as the benefits of local solutions, including improved air quality, tree canopy, and green space. “There are lots of opportunities to engage with the community, including speaking at public hearings, serving as an expert testimony, and writing letters to the editor,” she said.
The impact of these efforts can be further maximized by working with other healthcare professionals. Lori Byron, MD, a pediatrician from Red Lodge, Montana, who heads the AAP Chapter Climate Advocates program, noted during Q&A that every AAP chapter in the country has climate advocates. She added that the AAP is the first medical board to have climate modules in their maintenance of certification specifically designed to incorporate climate change education into well visits.
Adjusting Clinical Care
Meanwhile, in patient care, Matsui acknowledged it can be frustrating to think about what a massive impact climate has and simultaneously challenging to engage families in discussions about it. However, a wide range of resources are available that can be provided to patients.
“For a patient in front of you, being informed and prepared to talk about it is the first step to being able to assess their climate change risk and provide tailored guidance,” she said. Tailored guidance takes into account the child’s specific health situation and the risks they’re most likely to encounter, such as wildfire smoke, air pollution, longer pollen seasons, environmental allergens, or disruption of infrastructure.
“If I am seeing a patient with asthma who is allergic to a particular pollen, I can anticipate that pollen may be present in higher levels of the future, and that the season for that pollen may be longer,” Matsui said. “So if I’m thinking about allergen immunotherapy for that patient, future risk may be something that would push the conversation and the shared decision-making” from possible consideration to more serious consideration, depending on the child’s age.
“Another example is a patient with asthma, thinking about wildfire risk and having them prepared, because we know from data that wildfire air pollution is going to be worse for that child than pollution from other sources, and there are ways for them to be prepared,” Matsui said. For instance, having an HVAC system with a high-grade air filter (at least a MERV 13) will filter the air better if a wildfire causes smoke to descend over an area. Portable, less expensive HEPA filters are also an option if a family cannot upgrade their system, and wearing an N95 or N95-equivalent mask can also reduce the impact of high air pollution levels.
An example of thinking about the impact of potential infrastructure disruption could be ensuring patients have enough of all their medications if they’re close to running out. “It’s important for them to always have think about their medications and get those refills ahead of a storm,” she said.
Additional Resources
Understanding that pediatricians may not have time to discuss all these issues or have broader conversations about climate change during visits, Matsui highlighted the AAP website of resources on climate change. In addition to resources for pediatricians, such as a basic fact sheet about climate change impacts on children’s health and the technical report that informed the policy statement, the site has multiple resources for families:
- Climate Change Impact: Safeguarding Your Family’s Health and Well-being (video), How to Talk With Children About Climate Change, Climate Change & Children’s Health: AAP Policy Explained, Climate Checkup for Children’s Health: Little Changes With Big Impact, How Climate Change Can Make Children Sick: What Parents Need to Know, Climate Change & Wildfires: Why Kids Are Most at Risk, Climate Change, Extreme Weather & Children: What Families Need to Know, Extreme Heat & Air Pollution: Health Effects on Babies & Pregnant People, and
The following resources can also be helpful to pediatricians and/or families:
- Ready.gov, AirNow, Patient Exposure and the Air Quality Index, Protecting Vulnerable Patient Populations from Climate Hazards: A Referral Guide for Health Professionals from the US Department of Health and Human Services, Low Income Home Energy Assistance Program (LIHEAP), Weatherization Assistance Program, and the Disaster Supplemental Nutrition Assistance Program (D-SNAP)
In some states, Medicaid will provide or cover the cost of air conditioning and/or air filters.
