Hospitals can be hotspots for greenhouse gas emissions. But Boston Medical Center is part of a movement of hospitals changing their anesthesia to cut their footprint.

Megan Hall: Welcome to Possibly, where we take on huge problems like the future of our planet and break them down into small questions with unexpected answers. I’m Megan Hall.

If you’ve ever been put to sleep for surgery, you probably weren’t thinking about how that process affects the environment. But, it turns out, some forms of anesthesia create a lot of greenhouse gas emissions.

Hamid Torabzadeh and Meg Talikoff from our Possibly Team are here to explain.

Hamid Torabzadeh: Hi, Megan!

Meg Talikoff: Hello!

Megan Hall: Are you telling me I have to feel guilty about getting anesthesia during surgery? How does the stuff that makes me fall asleep have anything to do with climate change?

Hamid Torabzadeh: No one is asking you to feel guilty! Let’s just back up a bit to explain.

Meg Talikoff: General anesthesia, the medication that makes a patient unconscious during surgery, comes in a few different forms.

Hamid Torabzadeh: A lot of the time, it is a liquid that is vaporized and inhaled as a gas.

Meg Talikoff: What that means, is that it goes through the patient’s lungs, gets absorbed in the blood, and whatever is left over is exhaled by the patient back into the anesthesia machine.

Hamid: From that machine, the exhaled gas essentially gets dumped out into the atmosphere on the roof of the hospital.

Meg Talikoff: And that’s a problem because when those inhaled anesthetics get into the air, they help warm the planet, just like other greenhouse gasses.

Megan Hall: Interesting. Are all kinds of anesthesia the same?

Hamid Torabzadeh: Good question. Actually, no. One kind – desflurane – has what’s called a higher “global warming potential” than other anesthesia.

Meg Talikoff: That just means it’s a much stronger greenhouse gas than other anesthesia.

Megan Hall: Like how much more?

Meg Talikoff: Desflurane can warm the planet 2,500 times more than the same amount of carbon dioxide can.

Megan Hall: But it’s not like we’re powering our cars with this stuff. How many emissions could one surgery really create?

Hamid Torabzadeh: Let me put it this way, desflurane contributes the same greenhouse gas emissions during a five-hour surgery as taking a 2,000-mile car trip.

Meg Talikoff: And the US performs around 60,000 surgeries with anesthesia every day.

Hamid Torabzadeh: Anesthesia gasses aren’t anywhere close to the emissions from cars or heating houses, but chipping away wherever we can is the only way to get to zero emissions.

Megan Hall: Ok. So what do we do about this?

Meg Talikoff: Right here in New England, Boston Medical Center has almost completely stopped using desflurane.

Dr. Rafael Mauricio Gonzalez: Inhaled anesthetics, are all greenhouse gasses with global warming potential, so we targeted the one that was the highest, the worst of all the offenders.

Hamid Torabzadeh: That’s Dr. Rafael Mauricio Gonzalez, Boston Medical Center’s Vice Chair for Clinical Affairs and a practicing anesthesiologist.

Meg Talikoff: He says there are lots of other reasons why the hospital would switch away from desflurane, too:

Dr. Rafael Mauricio Gonzalez: In fact, it’s the weakest of the agents, so you have to use more volume. It’s the most expensive, it’s the most irritant to the patient. It’s pungent.

Hamid Torabzadeh: To wean itself off desflurane, Boston Medical Center restricted when it could be used, and made it less convenient to use.

Dr. Rafael Mauricio Gonzalez: If people had to use it, they had to go to the workroom, grab the vaporizer, which is heavy, bring it over, install it. It doesn’t take long, but it’s a pain in the butt.

Meg Talikoff: The technique worked. Anesthesia providers essentially stopped using it all-together.

Hamid Torabzadeh: Now, Boston Medical Center uses alternatives like sevoflurane.

Megan Hall: Is that anesthesia significantly better when it comes to greenhouse gas emissions?

Meg Talikoff: Yes. The same surgery with sevoflurane is equivalent to a 75-mile drive, which is way less than the 2,000 mile drive for desflurane.

Megan Hall: Wow! That’s actually a big improvement. Does it change anything for patients?

Meg Talikoff: Dr. Gonzalez says this switch has no impact on the quality or safety of care.

Dr. Rafael Mauricio Gonzalez: So between intravenous anesthesia and isoflurane and sevoflurane, for sure, everything is covered. No problem. You don’t need desflurane.

Hamid Torabzadeh: And Boston Medical Center isn’t the only place that’s ditching this anesthesia. Scotland banned desflurane in 2023 and the EU will follow in 2026.

Meg Talikoff: It’s nice to celebrate a win-win.

Hamid Torabzadeh: Moving away from this anesthetic seems to be better for patients and the planet.

Megan Hall: Great! Thanks, Hamid and Meg!

A new program at the Boston Medical Center says it prescribes solar panels to patients. But we wondered, what does that really mean?

Megan Hall: Welcome to Possibly, where we take on huge problems like the future of our planet and break them down into small questions with unexpected answers. I’m Megan Hall.

Recently I was talking to a friend of mine who works at the Boston Medical Center. She’s running a program that prescribes solar panels to patients.

I wanted to know more, so I sent Nat Hardy and Kolya Shields from our Possibly Team to Boston to check it out.

Nat Hardy: Hi, Megan!

Kolya Shields: Hello!

Megan Hall: So what’d you learn? Can a doctor really prescribe me solar panels?

Nat Hardy: Well yes and no! So the program is really exciting, but a doctor isn’t exactly going to write you a prescription that you can take to the pharmacy to pick up a solar panel.

Kolya Shields: What’s really happening, is they’re using solar panels to generate electricity, and that electricity helps cover the utility bills for their patients.

Nat Hardy: The program is called the Clean Power Prescription. To learn more, we talked to your friend- Doctor Anna Goldman. She’s a physician and the medical director of climate and sustainability at the Boston Medical Center.

Anna Goldman: We are under a solar canopy. So we can see the photovoltaic cells right above our heads and the sunlight streaming through.

Nat Hardy: The solar panels that we’re standing under are at the Boston Medical Center’s administration building. They generate enough energy to power about 50 homes around Boston.

Kolya Shields: The electricity made by these panels goes right into the local energy grid.

Anna Goldman The utility credits us for that energy on our account, and then we transfer the energy credits from our account to our patients accounts.

Nat Hardy: Those credits go to some of Boston Medical Center’s highest risk patients, people who don’t just need medical support, but also help with housing, mental health and other services.

Megan Hall: Okay so when people get that money, they use it to pay their electric bills?

Kolya Shields: Yeah Exactly! Anna says Boston Medical Center is the first healthcare system in the country to try something like this.

Megan Hall: Why is a medical center paying for its client’s energy bills?

Kolya Shields: Well, there are real health impacts if you can’t pay for your electricity!

Anna Goldman: If your utility is shut off you lose all the food in your fridge and you can’t keep fresh food in your home. And then there’s all kinds of medical devices that run on electricity.

Nat Hardy: Think about things like ventilators or oxygen concentrators…

Kolya Shields: Or even air conditioners! They help people stay healthy during the summer, especially older patients and anyone with a chronic condition.

Megan Hall: Yeah I guess that is pretty important! Are there any programs that help people keep their power on?

Nat Hardy: There are! Most states actually have programs that let doctors, like Anna, write letters to utility companies that prevent them from shutting off a patient’s power.

Anna Goldman: And I wrote one yesterday, actually, I write them frequently.

Nat Hardy: But the problem is, at least in Massachusetts, you still accumulate debt to the utility when this happens. Anna says a program that actually helps people pay their bills, can do more to address utility insecurity.

Kolya Shields: But she also says that it’s a bigger problem than just paying bills. Supporting patients financially also improves their health.

Anna Goldman: There’s a really straight through line between wealth and economic security and health outcomes. So if you’re spending so much of your money on a really basic need, like utilities, you don’t have funds to cover other really basic things.

Megan Hall:  So how many patients are actually using this program?

Nat Hardy: Yeah, so right now the program is just starting – Their goal is to enroll around 80 patients and they’ll all receive an average of $50 a month off their utilities.

Kolya Shields: But Anna’s already getting calls from other healthcare systems who want to try something similar.

Anna Goldman: There’s a lot of interest, because I think people see that this program addresses both environmental justice and economic justice and energy justice.

Nat Hardy: The program is partially paid for with a new tax credit in the Inflation Reduction Act, designed to fund solar projects that serve low-income communities.

Kolya Shields: Anna hopes  that the program will continue to expand so it can help more patients.

Megan Hall: Got it! Thanks, Nat and Kolya!
