Transcript
- 0:00Welcome to the Becker's Healthcare podcast. I'm Mariah
- 0:03Taylor, assistant editor, and I'm thrilled to have
- 0:05Arash Motamed,
- 0:07anesthesiologist
- 0:08and medical director of sustainability
- 0:10with Keck Medicine of USC
- 0:13on the podcast today. Doctor motamed, thank you
- 0:16so much for joining me. I'm really excited
- 0:18to learn more about how you're discontinuing
- 0:21nitrous oxide in the o r. But before
- 0:23we jump into that, I'd love if you
- 0:25could introduce yourself a little bit and tell
- 0:27us a little bit more about why you
- 0:28discontinued nitrous oxide.
- 0:31Well, hi, Maria. Thank you for having me
- 0:33on your podcast. It's my pleasure to be
- 0:34here today. I'll start off with, you know,
- 0:37my story and involvement with nitrous oxide.
- 0:40It started off with a pretty
- 0:42casual conversation with a colleague of mine who
- 0:46works at a competing medical center,
- 0:49and he was the one that first let
- 0:51me know what the
- 0:53problem with nitrous oxide is. And for those
- 0:55who may not know, it's also known as
- 0:57the laughing gas. It's a type of an
- 0:59anesthetic inhalational
- 1:01that
- 1:02has been used for over a century, but
- 1:05really started to gain a lot of popularity,
- 1:09in the latter half of this past century,
- 1:13and has some really great benefits in terms
- 1:15of quick onset, quick offset,
- 1:18and also, you know, very available
- 1:21and inexpensive.
- 1:22But what he told me at that time,
- 1:23which is really sort of the start of
- 1:27my journey in discontinuing nitrous oxide from our
- 1:29medical center, was
- 1:31a majority of the nitrous oxide that's in
- 1:34the central pipelines and the hospitals leaks into
- 1:37the atmosphere. So when they've done studies to
- 1:39look at that, they say anywhere from seventy
- 1:41five up to ninety five percent of the
- 1:44nitrous oxide leaks,
- 1:45typically at the areas of the connections.
- 1:49And there's really no way to prevent this.
- 1:51And, you know, what's interesting about it is
- 1:53what it means
- 1:55is that the nitrous actually
- 1:57never has any clinical impact. It just goes
- 1:59straight into the atmosphere. And then the next
- 2:01question is, well, why do we care about
- 2:03it? We do because
- 2:05nitrous oxide is a fairly potent
- 2:08greenhouse gas,
- 2:10about 300 times,
- 2:12as potent as carbon
- 2:14dioxide. So it really has a big impact.
- 2:16And on top of it, it does also
- 2:17deplete the ozone layer. And then one other
- 2:20thing with it is it lasts for a
- 2:22pretty long amount of time in the atmosphere,
- 2:24so about hundred years or so. So in
- 2:26some ways, some of the first nitrous oxides
- 2:29that were being used as anesthetics are still
- 2:31somewhere in our atmosphere,
- 2:33and most of it had gone unused in
- 2:35terms of,
- 2:37clinical
- 2:38benefit to the patient. Now we know the
- 2:40patient still gets the amount that we want
- 2:42the patient to get, but majority of it
- 2:44just leaks before it ever,
- 2:47gets to the patient.
- 2:49So knowing that and, you know, my involvement
- 2:52with our sustainability
- 2:53efforts at Keck, I felt
- 2:56compelled that we need to look at this
- 2:58and we need to figure out a way
- 2:59to better address it. And and,
- 3:01hospitals, nitrous oxide commonly comes in two forms.
- 3:04So either cylinders that gets attached to the
- 3:07anesthesia machine
- 3:08or central pipes that, again, gets connected to
- 3:11the anesthesia machine.
- 3:13Almost all the times, if a place has
- 3:15the central pipes, that's what they use, and
- 3:17the cylinder is used as a backup, you
- 3:19know, should there ever be any issues with
- 3:21central supply.
- 3:23So what we wanted to do was look
- 3:25at our usage at our medical center and
- 3:27decide, you know, whether it makes sense to
- 3:29discontinue it.
- 3:31The challenge with doing that, you know, one
- 3:34is,
- 3:35education and making sure that everyone has
- 3:38awareness as to why we're doing what we're
- 3:40doing, but, also,
- 3:42it's
- 3:44partnering with our, colleagues at facilities because, you
- 3:48know, as an anesthesiologist,
- 3:49I know nothing about, the central pipelines, how
- 3:52they work, and how they function.
- 3:55And, also, you know, at the end of
- 3:56the day, this is a medication that anesthesiologists
- 4:00have used for
- 4:01many decades. So there is clinical comfort,
- 4:05and when established habits that is,
- 4:09takes some time to,
- 4:11get them to see and understand and look
- 4:13at other alternatives. So that's
- 4:15the
- 4:16basics of the beginnings of how we got
- 4:18involved with, getting rid of, nitrous oxide.
- 4:22Excellent. And how did you build a credible
- 4:25business and clinical case for this initiative?
- 4:27And then on top of that, how did
- 4:29you get both hospital leadership and frontline physicians
- 4:33aligned on it?
- 4:34Yeah. That's a that's a really great question,
- 4:36and I think goes to heart of any
- 4:38type of initiative we try to do.
- 4:41It really needs to be collaborative, and you
- 4:42need to have the buy in because, otherwise,
- 4:43it's just not gonna go anywhere.
- 4:45What,
- 4:46I decided to do in this particular instance
- 4:50was,
- 4:51initially,
- 4:51I,
- 4:52you know, our department in anesthesia is about
- 4:55almost 200,
- 4:57individuals,
- 4:58combination of physicians, CRNAs, and, residents.
- 5:02And I picked
- 5:04about 20 of them who
- 5:06either have leadership roles or, you know, are
- 5:08otherwise still fairly influential or have, you know,
- 5:11a lot of experience and expertise,
- 5:13and I pulled them. And my first question
- 5:16to them was, you know, are there any
- 5:18types of cases that we do where nitrous
- 5:20oxide is really the only
- 5:23type of anesthetic we should use for? Because
- 5:26if that answer
- 5:27comes back as yes and a fair amount,
- 5:29then it's a different question. But, you know,
- 5:31as an anesthesiologist myself, I know the answer
- 5:33is no.
- 5:35And that was the response that I got,
- 5:37which was great. So then it led to
- 5:39the next question on on the next round
- 5:41of surveys that we did, which was,
- 5:43since we know that, you know,
- 5:46it's not a must have,
- 5:48can we have the option
- 5:50of,
- 5:51a, fully getting rid of everything that we
- 5:53have?
- 5:54Two,
- 5:55discontinuing
- 5:56the central pipeline and just having the cylinders
- 5:59as backup should anyone need it?
- 6:01Or three,
- 6:03removing everything, but having a few cylinders somewhere
- 6:07in the building as backup should anyone need
- 6:09it, and we'll bring it up and connect
- 6:11it to the machine.
- 6:12And it was interesting
- 6:14that, you know, through that process and, of
- 6:16course, as as these surveys are happening, there's,
- 6:18you know, education,
- 6:20with the department and forms of, you know,
- 6:22grand rounds,
- 6:23to let them know what the impact of
- 6:24nitrous oxide is. But most of the group
- 6:27felt comfortable moving towards
- 6:29an approach where we remove everything from the
- 6:31OR. So it's not there ready to be
- 6:33used,
- 6:34but we'll have cylinders available should we ever
- 6:37be in a need where someone feels like
- 6:39that that is the best thing for for
- 6:40their patient at that point in time. So
- 6:42we reserved four cylinders,
- 6:45where we keep all the the gas cylinders
- 6:47in our hospital and created a pathway that,
- 6:49you know, is easy to follow and a
- 6:51phone number to dial, and the person comes
- 6:53in and helps set it up. And what
- 6:56was really interesting
- 6:57was,
- 6:59in the last
- 7:01three years at our Keck Hospital and two
- 7:03years at Norris Cancer Hospital, not a single
- 7:06time has anyone needed to make that phone
- 7:08call,
- 7:09which essentially made us,
- 7:11the,
- 7:12only institution that I know of in The
- 7:14US that has fully removed nitrous oxide from
- 7:17both central supply and the cylinders.
- 7:22That's incredible.
- 7:23What were some of those key learnings you
- 7:25had when you were moving this from a
- 7:27concept into execution?
- 7:30So one of the,
- 7:32interesting
- 7:33things that came up that we did not
- 7:35know was
- 7:36the way the nitrous is set up to
- 7:38the machine. Once you discontinue it, that machine
- 7:40could no longer do its self check and
- 7:43would give a lot of errors, so it
- 7:44would be nonfunctional.
- 7:46So we first had tried this on one
- 7:49of our spare machines just to see what
- 7:50happens. And once we realized that that's a
- 7:52problem, we needed to
- 7:53connect with the manufacturer,
- 7:56and have one of their representatives come in
- 7:58because they needed, you know, special codes to
- 8:00go in there and change the machine check
- 8:02so that it doesn't alarm and it can
- 8:03still do itself check and it can still
- 8:05function. So that was an interesting learning point.
- 8:08But one of the other things that was,
- 8:11could potentially sometimes I think in other institutions
- 8:13also be viewed as barrier is the term
- 8:17that gets used frequently when it comes to
- 8:19removing nitrous oxide from central
- 8:22supply or central pipelines is decommissioning.
- 8:25And decommissioning can mean different things to different
- 8:27people as as I have learned, and it
- 8:30could be anything from we're just not using
- 8:32the pipes to we need to go into
- 8:34the building and we need to remove pipes,
- 8:36which, of course,
- 8:38is not only a construction nightmare, but also
- 8:41fairly expensive and, you know, regulatory challenges that,
- 8:44you know, may come with it. Our approach
- 8:46to decommissioning
- 8:48was not to do any of that. It
- 8:50was to simply
- 8:51stop having nitrous oxide in those central pipelines.
- 8:55And then our the our team with, the
- 8:58facilities management actually came up with a really
- 9:01brilliant and unique idea, which I think can
- 9:04be used by other hospitals as well, which
- 9:05is to fill that pipes with, nitrogen,
- 9:09which is also another gas that helps preserve
- 9:12the integrity of the pipes should there be
- 9:15some other use for them down the line,
- 9:17for some other form of gas. But at
- 9:19the same time, it's also inexpensive, and it
- 9:21doesn't have any negative environmental impact.
- 9:25That's amazing. Some really interesting problem solving and,
- 9:27you know, issues that probably nobody had thought
- 9:30about before you tried.
- 9:31So I'm curious if we take kind of
- 9:33a step back. And when you're evaluating
- 9:35sustainability initiatives as a whole, how are you
- 9:38balancing the environmental impact with the financial performance,
- 9:42clinical outcomes, all the operational feasibility,
- 9:45and then how are you measuring the success
- 9:47beyond just emissions numbers?
- 9:50Yeah. That's the that's the tough question that
- 9:53we try to figure out. Actually, with every
- 9:55single project that we do, we're fortunate in
- 9:57that,
- 9:58at our institution,
- 10:00there has been, you know, support to the
- 10:03sustainability
- 10:03program.
- 10:05So we have a chief of sustainability and
- 10:07a sustainability program manager.
- 10:09And along with, you know, me and my
- 10:11role, what we try to do with all
- 10:13of these initiatives is partner with the various
- 10:15stakeholders
- 10:16at our hospital,
- 10:18you know, whether it's, you know, obtaining data
- 10:20or whether it's talking with supply chain
- 10:23to try to figure
- 10:25out what the impact is
- 10:27both financially
- 10:28and to the some of the contracts because,
- 10:30you know, the hospitals may be tied to
- 10:32certain contracts, so we can't just suddenly go
- 10:33and say this is what we wanna do.
- 10:36And then, of course, the
- 10:38I would say both, you know, the return
- 10:39on investment from an environmental point of view
- 10:42or from a cost point of view.
- 10:44There are projects
- 10:45that, you know, will be very expensive with
- 10:48maybe not so much,
- 10:50significant environmental
- 10:52impact in terms of reducing carbon footprint, and
- 10:55then there's projects that are exactly opposite. So
- 10:57in our approach so one, we collect as
- 11:00much data as we can,
- 11:02to before, during, and after. And we have
- 11:06committees,
- 11:07that meet very regularly on a monthly basis
- 11:09with all the various,
- 11:11individuals,
- 11:12within the health system that play a role
- 11:14in one form or another and the the
- 11:17care that we deliver to make sure everyone's,
- 11:19on board with the projects and it makes
- 11:22sense.
- 11:23Of course, clinicians,
- 11:25are very much involved in we, you know,
- 11:28we really listen to their input, and that's
- 11:29part of my role is to bring them
- 11:31on board and make sure, you know, nothing
- 11:33that we do ultimately has a negative impact
- 11:35on patient care.
- 11:37But what we try to do, I would
- 11:38say, on a very high level is most
- 11:41of the projects that we decided to tackle
- 11:43earlier on were the types of projects that
- 11:46would achieve both. And that's, I think, one
- 11:48of the other misconceptions with a lot of
- 11:50these efforts to reduce the carbon footprint, of
- 11:53care delivery is everyone just assumes it's gonna
- 11:55be expensive.
- 11:56And when you look at, you know, how
- 11:58can we better be better for our environment,
- 12:00the number one thing everyone just says is,
- 12:02you know, reduce waste.
- 12:04Reducing waste is obviously, you know, financially beneficial
- 12:08as well as well, you know, in in
- 12:10addition to,
- 12:11reducing the negative impact of the on the
- 12:15environment. In in
- 12:17health systems,
- 12:18there is a fair amount of waste. And
- 12:21when you look at health systems, specifically the
- 12:24academic medical centers and part of that cost
- 12:26of education
- 12:28also becomes access waste. So, you know, for
- 12:30all of us who, you know, myself as
- 12:31an anesthesiologist
- 12:32in the operating room, we do see that
- 12:35all the time. And part of it is,
- 12:38just the
- 12:39the practice of medicine and helping teach somebody
- 12:43else and helping somebody else become,
- 12:46a clinician. But I think the other part
- 12:48of it is we've historically, as an entity,
- 12:51never
- 12:52truly looked at how much waste we generate
- 12:54and what the impact is. And now we
- 12:56know that health care is one of the,
- 12:58you know, leading industries when it comes to,
- 13:02greenhouse gas emissions. You know, studies have said,
- 13:05at least in The US, anywhere from eight
- 13:07to 10%,
- 13:08and we're much higher compared to other institutions
- 13:10outside of the country.
- 13:12Absolutely. And I know here at Becker's, we've
- 13:15seen a lot of hospitals that are starting
- 13:17to move forward with sustainability initiatives in a
- 13:20lot of different ways.
- 13:21But I'm curious from your experience, where do
- 13:24you see the biggest untapped opportunities for hospitals
- 13:27to reduce their environment footprint?
- 13:29Yeah. I I think from my point of
- 13:31view, the the biggest untapped opportunity is still
- 13:34lack of education.
- 13:36I I think, you know, again, using myself
- 13:39as as the
- 13:41example of it. The first time I went
- 13:43into a, grand rounds where some individual was
- 13:46talking about the impact
- 13:48of care delivery on carbon footprint was sort
- 13:50of my moment of, you know, I need
- 13:52to get involved, and what do I need
- 13:53to do? And I think that is there's
- 13:56still a great opportunity there, and
- 13:58clinicians really need to be involved. There are
- 14:01some,
- 14:02hospitals or health care systems where they're doing
- 14:04a fair amount,
- 14:06in terms
- 14:07of reducing energy usage or water usage, but
- 14:11the clinicians haven't been fully,
- 14:14engaged. So
- 14:16educating and connecting both the hospital,
- 14:21administrative side and the clinical side together, I
- 14:24think, really makes a big difference from our
- 14:26point of view. You know, once once we
- 14:28got that group together, the project's just one
- 14:31feeds the other. You know, when we started
- 14:33our monthly OR group, talking about how can
- 14:36we, you know, do better in the peri
- 14:38op setting,
- 14:39I remember the first session I had, you
- 14:41know, afterwards, I'm like, oh my god. I
- 14:43have nothing to say next month. I just
- 14:44went over everything I had to say.
- 14:46And now it's at a point, you know,
- 14:48two years later where there's not enough time
- 14:50to keep talking about all the different things
- 14:52that people wanna do.
- 14:54The different folks in the hospital, whatever their
- 14:56role and responsibility is, are the ones that
- 14:59come to us with the ideas.
- 15:01We have one of the individuals at our
- 15:02hospital that,
- 15:04does patient transport is the one that, you
- 15:06know, came up with idea of how to
- 15:07try to create bins for,
- 15:10the the significant battery waste, that we have
- 15:14in hospital for all the devices that we
- 15:15use. So the idea is slow once you
- 15:18have that set up,
- 15:20and, you know, you have the key individuals
- 15:23involved. So I think from my point of
- 15:24view, the biggest barrier is that first step.
- 15:26And once you take that first step, it
- 15:28just ends up feeding itself. And at the
- 15:30end of the day, gets us to a
- 15:31place where we
- 15:33deliver better care because in my view, the
- 15:35best care you can deliver is also the
- 15:37most sustainable one where the patient does well
- 15:39and they don't have to come back to
- 15:40the hospital again or be readmitted
- 15:43to the hospital or have a prolonged hospital
- 15:45stay.
- 15:46And,
- 15:47as you we do that, we're able to
- 15:49deliver more care and actually do it in
- 15:51the most cost effective way. So for me,
- 15:54that mentality is just very much aligned with
- 15:57value care that we, you know, aspire to
- 16:00deliver.
- 16:01Absolutely.
- 16:02Well, this has been such an informative discussion.
- 16:05Thank you for taking the time to join
- 16:06me today and share more about everything you're
- 16:08doing.
- 16:09Thank you so much. I appreciate being here.
