Rational Use Of PPE In COVID - 19
5 Plays6 years ago
In this episode of Critical Matters, we continue to discuss issues related to the COVID- 19 pandemic. The numbers of cases continue to rapidly climb in the US and the world. There are serious concerns for adequate supplies of personal protective equipment for clinicians. In today’s episode we talk about the rational use of personal protective equipment. We try to focus on facts over fear. The discussion is an excerpt from a webinar Dr. Zanotti presented to Sound's national group of clinicians.

US as COVID-19 Epicenter
00:00:33
Speaker
Since our last episode on Critical Matters,
00:00:35
Speaker
the COVID-19 pandemic has continued to grow exponentially around the world.
00:00:43
Speaker
Today, the United States is becoming the epicenter of the worldwide pandemic, and we are seeing a rapidly increasing number of cases throughout the country, with some areas such as New York, California, and Washington State taking the brunt of these cases.
00:01:04
Speaker
On today's episode,
00:01:05
Speaker
of the podcast, we will continue to talk about COVID-19, but we will focus on personal protective equipment and a lot of the anxieties around the potential lack of proper PPE for frontline clinicians.
PPE Shortages and Clinician Anxiety
00:01:22
Speaker
With a worldwide impact and supply chains affected as they are, it is possible and likely in some places that shortages on PPE will be encountered
00:01:34
Speaker
by clinicians caring for patients with COVID-19.
00:01:38
Speaker
This has created a tremendous amount of anxiety among clinicians, rightfully so.
00:01:44
Speaker
However, I do believe that there's always things that we have under our control that we can apply to mitigate and minimize the risk of ourselves and coworkers contracting the virus at the front lines.
00:02:00
Speaker
And I think it's very important for us to try to differentiate facts from fear
00:02:04
Speaker
and understand the available evidence and comprehend how we can best apply that at the bedside to keep us as safe as possible.
Webinar on PPE Usage
00:02:14
Speaker
In today's episode, I'll share a segment of a webinar that we held with my co-chief medical officers at Sound Physicians, Gregory Johnson for hospital medicine and Nate Ruck for emergency medicine to our providers.
00:02:31
Speaker
And specifically, we'll share a portion where I addressed
00:02:34
Speaker
the irrational use of personal protective equipment.
00:02:38
Speaker
Before we get into the recording, I think it would be appropriate to share a quote from Viktor Frankl, which I think speaks highly to the situation that today we're living that is unprecedented in our clinical careers.
00:02:57
Speaker
When we are no longer able to change a situation, we are challenged to change ourselves.
00:03:03
Speaker
Without further ado, this is our webinar on rational use of personal protective equipment.
Acknowledgment of Healthcare Teams
00:03:12
Speaker
As John said and Greg said, I want to first start by thanking everybody for all the hard work.
00:03:18
Speaker
The stories that are coming from the field are amazing.
00:03:21
Speaker
I think not unexpected because I've met many of our teams and I know that this is an opportunity for them to really create value and serve the communities that we're in.
00:03:31
Speaker
Just as a general sound physicians update, like John mentioned, the number of cases continues to increase across all service lines.
00:03:39
Speaker
We will continue, the CMOs, John and Mark, working on the webinar series.
00:03:44
Speaker
A lot of the questions that you write, if they go unanswered, will help us guide future content.
00:03:49
Speaker
We also have a series of specialty-specific communications.
00:03:53
Speaker
that will continue.
00:03:54
Speaker
And I just want to assure you that the entire organization is focused on the front line and trying to really provide all our clinicians with the best tools possible to really try to make a difference with this pandemic and help our communities.
Rational PPE Usage Discussion
00:04:08
Speaker
So today's focus will be on clinical guidance on the rational use of personal protective equipment and keep our clinicians safe.
00:04:17
Speaker
And before I start, I think it's worth remembering
00:04:22
Speaker
that this is a very fluid situation.
00:04:25
Speaker
It's a novel virus.
00:04:27
Speaker
There is an enormous amount of information that is coming in.
00:04:31
Speaker
Not all the information is the same quality.
00:04:34
Speaker
There's a lot of information that also we have learned from previous pandemics of similar coronaviruses.
00:04:41
Speaker
And I think that ultimately what we need to understand is that these are unprecedented times for us as clinicians.
00:04:48
Speaker
And there are things that we will need to do probably that we never thought we would have to do.
00:04:52
Speaker
And I think that one of the tools that we can offer our clinicians is knowledge.
00:04:59
Speaker
And knowledge really is focusing on what are the things that we control, what are the things that we understand, eliminate noise and focus on moving things forward and really trying to make a difference.
Social Distancing Efforts
00:05:11
Speaker
So as we said earlier,
00:05:14
Speaker
The goal here is to create the greatest amount of good for the greatest number of people.
00:05:18
Speaker
From a community perspective, I think the whole country has embraced, the whole world actually has embraced this concept of flattening the curve by implementing social distancing and other intervention at a community level.
00:05:30
Speaker
We are hoping that we can manage the surge of cases
00:05:35
Speaker
and that really we don't overwhelm every hospital system in America.
00:05:39
Speaker
As many of you might know, there are hospital systems such as New York that right now are at the brink and really, I mean, are taking an influx of patients that is something that we've never seen.
00:05:50
Speaker
And I think that we're hoping that with all these measures, we can really create the greatest good for the greatest number and get through together as a team.
PPE Needs vs. Availability
00:05:59
Speaker
So why is this concept of rational use of personal protective equipment,
00:06:05
Speaker
being mentioned.
00:06:05
Speaker
And I think that it's very important to just face reality and acknowledge that there's what we want, there's what we need, and there's what we have.
00:06:19
Speaker
And we have to make sure that we can align those as best we can.
00:06:24
Speaker
Now, this whole idea of being rational about the way we use protective equipment, I think is something that has never really been an issue for us because we've never
00:06:34
Speaker
faced a situation like this.
00:06:36
Speaker
We would have one patient that needed isolation and you could get all the equipment you needed.
00:06:41
Speaker
But now we're really seeing a lot of patients in a scale that we never thought and that's overwhelming, not only hospitals in America, but across the world.
COVID-19 Transmission and PPE
00:06:50
Speaker
There are three buckets that I think are very important in considering and constructing a framework for rational use of personal protective equipment or PPE.
00:07:02
Speaker
Number one,
00:07:03
Speaker
is understanding COVID-19 transmission, how the virus is transmitted.
00:07:08
Speaker
There's a lot we have learned.
00:07:09
Speaker
There are still things we don't know, but I think that understanding the available evidence helps us as clinicians anchor ourselves on reality and try to prioritize the best way we can with the context that we have to live at each one of our programs.
00:07:25
Speaker
Number two is the proper use of PPE based on what we understand of COVID-19 transmission, but also
00:07:33
Speaker
based on the reality of the place that we are in.
00:07:36
Speaker
And I think that the third bucket, which is disruption of supply chains, is something that we have never experienced in the scale that we're experiencing right now.
00:07:45
Speaker
And that disruption of supply chains is really due to many, many, many reasons.
00:07:50
Speaker
Number one, the epidemic started in China, which is where most of these factories reside.
00:07:57
Speaker
A lot of those factories are closed.
00:07:59
Speaker
And number two, it's a pandemic that's affecting the whole world.
00:08:03
Speaker
So never have we seen a surge of need at the same time at such a scale for these type of PPE.
00:08:13
Speaker
Number three is a massive hysteria in the community where people went and bought things that they can't use, don't need, and don't even know how to use and price gouging.
00:08:25
Speaker
And there's a lot of that going on, which ultimately has also obviously impacted the clinicians at the bedside.
00:08:33
Speaker
Having said that, I do think that there are things that we do, we can understand, there are things that we can do, and I would really emphasize that everything I present is based on the best available information and evidence that is out there.
00:08:48
Speaker
I rely heavily on WHO, on CDC, on peer-reviewed journals.
00:08:54
Speaker
I think that there's a lot of information on social media that is not actionable data sometimes, but I really think that if you think about this,
00:09:02
Speaker
as a clinician, as a scientist, there are some things that you can understand, some things that you can infer, and I think ultimately use a rational approach to guide how we deal with this, because I think that's ultimately the best chance we have to be safe and to protect ourselves and our teams.
00:09:24
Speaker
So what do we know about COVID in terms of transmission?
00:09:30
Speaker
Based on the best available evidence,
00:09:33
Speaker
The virus of COVID-19 is transmitted between people through close contact and droplets.
00:09:39
Speaker
And I think that that's a very important concept because everything that we know so far indicates that that is the way that this is transmitted.
00:09:48
Speaker
Now, there's other ways that we will talk in a second that are potential or plausible, but let's focus on what we do know.
00:09:56
Speaker
We do know that close contact and droplets are the key.
00:10:00
Speaker
And in terms of close contact, what does that really mean?
00:10:03
Speaker
It means being close to somebody in a length of less than six feet or one meter.
00:10:10
Speaker
And in terms of prolonged contact, some healthcare organizations such as the CDC at Singapore, they find it as 30 minutes of close contact without protection.
00:10:21
Speaker
And others such as Hong Kong, they find it as 15 minutes.
00:10:24
Speaker
But again, this is not, you just walk by somebody and you're gonna get COVID-19.
00:10:29
Speaker
It's related to droplets and close contact.
00:10:32
Speaker
Now, one of the likely ways that this happens is that you get droplets on your hand and then you rub them in your eye, your nose or your mouth.
00:10:40
Speaker
And that's an easy way of transmitting the virus.
00:10:44
Speaker
And that is why frequent hand washing is perhaps the most powerful tool we have both in the community and at the hospital level to prevent dissemination of this virus.
00:10:56
Speaker
Other community-based strategies or measures
00:10:58
Speaker
that are important are avoid touching your face, your eyes, your mouth and your nose in particular.
00:11:05
Speaker
Respiratory hygiene in the community, which means if somebody's gonna sneeze or cough to do it in their elbows and if they use a napkin or a tissue paper to dispose that tissue paper immediately and wash your hands.
00:11:18
Speaker
The use of medical masks, which are prevalent for the last several months around the world in communities and airports
00:11:26
Speaker
even in some hospitals, are only indicated for those who have symptoms.
00:11:31
Speaker
And they're indicated for those who have symptoms so that they will decrease the transmission of droplets to others.
00:11:37
Speaker
And finally, the whole idea of social distancing.
00:11:40
Speaker
More and more counties and states are going into quote-unquote lockdown, but the whole idea really of people staying home, people not gathering with other people, and especially, I think, for those who have symptoms or are COVID-19 positive,
00:11:56
Speaker
it's very, very important.
Global Lockdown Efforts
00:11:57
Speaker
So these measures are what I think as a society, public health officials are trying to push through and we're seeing different measures of this throughout the world, but in one way or the other, the world as we know it today is different.
00:12:13
Speaker
Today they announced a lockdown in India.
00:12:15
Speaker
It's the largest lockdown in the history of humanity, 1.2 billion people in lockdown.
00:12:21
Speaker
And I think it just illustrates
00:12:23
Speaker
to how people are concerned about this virus, but also that these measures actually can impact the number of transmissions.
00:12:32
Speaker
Now, there's been a lot of talk and a lot of concern about fomites and aerosol.
00:12:39
Speaker
And I think it's very important to understand that where this comes from.
00:12:43
Speaker
So all the clinical evidence available so far has indicated that the transmission of COVID-19 virus, the COVID-19 virus,
00:12:53
Speaker
producing virus is through close contact and droplets.
00:12:57
Speaker
There is one particular research published as a correspondence to the New England Journal of Medicine earlier this month where they, under experimental conditions, were able to show viable virus generated in aerosols and in different types of fomites such as copper, cardboard, stainless steel, and plastic.
00:13:19
Speaker
So nobody has been able to link this
00:13:23
Speaker
experimental finding to solid clinical evidence that this has caused a transmission of the virus.
00:13:30
Speaker
However, I think that it does bring up the point that that mode of transmission is plausible.
00:13:36
Speaker
In terms of aerosols, what that means is that what are situations that are most likely to generate circumstances similar to the ones that they had in the experiment?
00:13:47
Speaker
They're not a lot.
00:13:48
Speaker
but there are some aerosol generating procedures such as intubation, extubation, bronchoscopy, non-invasive positive pressure ventilation, nebulizers, CPR bagging that might fall in those categories.
00:14:03
Speaker
And you'll see throughout the discussion that that's why we're prioritizing certain types of airborne precautions for those situations.
00:14:11
Speaker
On the other hand, in terms of fomites, there is no clinical evidence that suggests that the fomites are an issue.
00:14:17
Speaker
but we do know that cleaning of our hands and cleaning of surfaces with soap appropriately, as we'll talk for hand washing and with alcohol-based products eliminates the virus.
00:14:29
Speaker
So again, even if fomites are a plausible source of contamination, I think that we do have tools that when applied in a consistent manner can mitigate that risk significantly.
00:14:42
Speaker
Now, in terms of experimental,
00:14:45
Speaker
Evidence based on this publication in this paper, you can see that both for aerosols and fomites, there's a possibility for the virus to remain alive.
00:14:57
Speaker
In terms of epidemiological evidence, it's been hard to prove, but from an airborne perspective, we do have some evidence to suggest that if we prevent droplets, we're in good shape as healthcare providers.
00:15:13
Speaker
But also the other evidence that I think is very important is with over 300,000 positive cases around the world and many more that are untested, over and over again when people have been quarantined, it has not been that they consistently infect everybody in their household.
00:15:29
Speaker
So if you take a good droplet precautions and you have a sick patient with COVID in your home or a positive COVID patient, it doesn't mean that everybody gets sick, which makes me think that if airborne were an important mode of transmission,
00:15:41
Speaker
on a regular day-to-day basis, that would be impossible.
00:15:45
Speaker
The spread of disease would be incontainable in households because those houses have no way of filtering the air.
00:15:52
Speaker
So as you can see, there is some epidemiological data that would suggest again that the main mode of transmission is droplets, that fomites and
00:16:02
Speaker
aerosols, other plausible are much less likely.
00:16:05
Speaker
And furthermore, in the clinical experiments that have looked at either exposure of a healthcare provider workers or in large randomized trials, not with this particular virus, but with influenza and other similar respiratory viruses, they have shown that the surgical face mask of droplet precautions have the same protection as those with N95 and other respirators.
00:16:32
Speaker
more evidence suggesting that perhaps the aerosol and the fomites are less relevant, but that we should still, because they're plausible, maybe focus on super high risk situations and what are the factors that we have to mitigate that.
00:16:47
Speaker
So we talked about community interventions and we talked about social distancing.
00:16:53
Speaker
I am making a very strong urge for everybody in our programs to really start thinking about how do we
00:17:02
Speaker
produce or how do we implement social distancing in the hospital, especially in the ICU, but I'm sure in the ED and also in our hospital teams.
00:17:12
Speaker
We work in groups.
00:17:13
Speaker
We do MDRs.
00:17:14
Speaker
I think we're going to have to start rethinking how we do that.
00:17:17
Speaker
We want to keep as much distance as we can because a lot of healthcare provider workers are getting sick around the world from other healthcare provider workers who have symptoms, and I think that that's going to be very important.
00:17:28
Speaker
So rethink how you do MDRs.
00:17:31
Speaker
Meetings should be virtual as much as possible.
00:17:35
Speaker
If it's a small number of people, maybe with enough distance, it's okay, but start rethinking how we do meetings.
00:17:41
Speaker
Rethink how we socialize at the hospital.
00:17:44
Speaker
I think that we need to support each other, but we have to be smart about things, and maybe after a tough shift, going out for happy hour in the big group is not the best idea.
Hospital Social Distancing Measures
00:17:54
Speaker
And then I think another issue that I think is very relevant is our work areas and call rooms.
00:18:00
Speaker
I have visited many of our programs, and I know a lot of our programs have call rooms where the clinicians and the rest of the team work together.
00:18:09
Speaker
Think about how do I implement not only social distancing there, but how do we clean things appropriately?
00:18:14
Speaker
How do we disinfect computers?
00:18:16
Speaker
How do we disinfect our phones?
00:18:19
Speaker
And really start thinking very deliberately about implementing social distancing, not only when we're out of the hospital, but when we're at work.
00:18:30
Speaker
what can we learn about healthcare providers from other experiences?
00:18:34
Speaker
There was a very interesting article that was shared by John earlier this week by Atul Gawande, and there's also other reports available through WHO and other sources that basically talk about what has happened in different places that have either been through the surge of their epidemic or are still in the midst of that, but have had more experience in terms of
00:18:59
Speaker
dealing with this for a longer time.
00:19:01
Speaker
And there's three, I think, that come to mind immediately that might give us some clues that might be useful for us to focus on what are the things that we can do that might help.
00:19:11
Speaker
So obviously, as you all know, the first epicenter of the pandemic was in Wuhan, China.
00:19:17
Speaker
In the initial wave at Wuhan, over 1,300 healthcare workers became COVID positive.
00:19:24
Speaker
Now, they really had a big problem with their healthcare workers force, and at one point, they were able to implement very draconian rules everywhere and were able to change the trajectory at other places in China, but they were able to bring in over 40,000 healthcare workers from other places in China to work in Wuhan.
00:19:47
Speaker
Now, these had bunny suits, N95s, droplet precautions,
00:19:53
Speaker
And they really, I mean, were very aggressive in having that for everybody.
00:19:57
Speaker
And it's very interesting that based on what's reported from that second wave of providers, zero got infected.
00:20:04
Speaker
So I think that that gives us hope that with the right implementation, we obviously can keep our workforce safe in the hospital.
00:20:15
Speaker
Now, the reality also is that we don't have all those suits, but they mostly did it based on
00:20:22
Speaker
use of N95s and droplet precautions as well.
00:20:24
Speaker
So let's look at other experiences and see what we can
Italy's Healthcare Collapse
00:20:27
Speaker
learn.
00:20:27
Speaker
The second epicenter of the pandemic has been in Italy.
00:20:33
Speaker
And as many of you know, Italy has been struggling for the last several weeks, especially in the northern area of the country, in Lombardy, with really a collapse of the healthcare system.
00:20:44
Speaker
There's been 8% of the infected COVID positive people are healthcare workers.
00:20:49
Speaker
they represent 1% or 2% of the population.
00:20:52
Speaker
So clearly that is an increased risk.
00:20:55
Speaker
And this has not been published, but in a webinar that was presented by WHO late last week, the head of the Italian Critical Care Societies was sharing their experience.
00:21:07
Speaker
And one of the things that he was very clear about was that when they have analyzed and looked at their healthcare worker that were positive, they do believe that a lot of people got exposed
00:21:19
Speaker
early on that they did not have droplet precautions and that a lot of the exposure also may have happened from socialization before and after work and that the healthcare providers themselves, the workers, were an enormous vector for transmission of the disease.
00:21:36
Speaker
So really, I mean, a lot of people have had the opportunity to hear these webinars from our Italian colleagues and to participate in some of these calls.
00:21:43
Speaker
Their plea is to be
00:21:44
Speaker
very diligent with PPE to prioritize, to make sure that people are utilizing it in the right way.
00:21:52
Speaker
And the third experience that I think is actually a shared one from Hong Kong and Singapore, where they had early rises in cases and took very decisive action, it might be more comforting for us in the United States because they did, at Singapore, they did utilize a very rational use of PPE.
00:22:14
Speaker
which they really prioritized the N95s for the situations where high aerosols might be produced or for the positive patients.
00:22:23
Speaker
They used droplet precautions in everybody and they also went further in terms of making sure that standard precautions such as washing your hands deliberately and using just regular gloves and even just a regular face mask for other patient interactions was done as early as possible and they have shown zero
00:22:41
Speaker
healthcare workers infected so far based on their reports.
00:22:45
Speaker
Very interesting also is that based on an exposure, one pneumonia patient in Singapore that exposed 41 healthcare workers, of which I think 85% of them had only dropped the precautions and only 15% had used at one point N95s.
00:23:03
Speaker
All those healthcare workers had, over a course of 14 days,
00:23:07
Speaker
double testing and none of them turn positive, suggesting that if we take the right droplet precautions and prioritize the N95s and airborne for the highest risk procedures, we can really keep our healthcare workers safe.
00:23:23
Speaker
So again, I think that this is information that I think is valuable.
00:23:28
Speaker
It doesn't give us all the answers, but I think that it would be foolish not to try to understand what has happened elsewhere
00:23:35
Speaker
as this pandemic continues to grow and affect the rest of the world.
Rational PPE Guidelines
00:23:40
Speaker
So let's move on now to talking about what we really consider rational use and how we should be thinking about this based on what we know, based on what we understand, and based on what the WHO and CDC have recommended.
00:23:55
Speaker
So in an ideal world, we would have all the PPE we want, understand exactly what we need, and not have to worry about it.
00:24:06
Speaker
In a pandemic world, that might not always be possible or that potentially could be a problem.
00:24:12
Speaker
So the way we optimize PPE availability is we use PPE appropriately, we minimize the need for PPE, and we do the best we can as a hospital, as a group, as a city, as a state, and as a country to coordinate PPE supply chains.
00:24:30
Speaker
And we'll talk about each one of these a little bit more.
00:24:34
Speaker
So in terms of
00:24:36
Speaker
Minimizing PPE need, I think that the first thing that we have implemented at Sound Physicians and we're trying to push forward, and there's different ways we can do this, is the use of telemedicine, especially for triaging and for patients who are not as sick.
00:24:50
Speaker
A lot of this can be done through telemedicine.
00:24:54
Speaker
There's been other seminars or webinars from Sound on the application and how to deploy this.
00:25:00
Speaker
The second is physical barriers.
00:25:02
Speaker
And that is very important for our ED colleagues, especially for triage, figuring out ways to triage people who might have COVID-19 so that we don't disseminate or infect all people.
00:25:15
Speaker
And I know that Nate and his team talked about that earlier today in terms of how to use TENS and outside triaging for a lot of patients who might not require hospitalization, but that who might still be positive and spread the disease.
00:25:33
Speaker
The restriction of healthcare workers, I think, is very important from entering the room.
00:25:37
Speaker
Think about how to minimize the number of times we need to do things.
00:25:42
Speaker
Labs should be drawn at once.
00:25:45
Speaker
People should be doing certain checks when they're giving medications.
00:25:48
Speaker
Consultants don't need to go into the room unless they really are going to examine the patient for something that's going to change management.
00:25:56
Speaker
Obviously, at this point, I think most hospitals with
00:25:59
Speaker
trainees and students have limited that number.
00:26:02
Speaker
Visitors is another big component of that.
00:26:05
Speaker
And I think that a lot of hospitals, depending where they are, are moving to more and more restrictive visitor policies.
00:26:11
Speaker
Obviously that has, may have positive impact and decreasing spread in the community and among healthcare workers, but I think it also has significant impacts on the community in terms of what it means in a time of crisis.
00:26:26
Speaker
And I think it's important for us to think about this because our kindness and compassion are probably not gonna be enough to help everybody that really is gonna need help.
Emotional Impact of Visitor Restrictions
00:26:37
Speaker
But it has happened in other places like in Italy when patients are dying by themselves and family members are not there.
00:26:45
Speaker
So just think about the toll that this takes not only on us as healthcare workers, but on everybody in the community.
00:26:52
Speaker
Other options to minimize PPE,
00:26:56
Speaker
In some places, depending on the structure of your hospital, what's available, what's possible, cohorting might help eventually to minimize the use of PPE.
00:27:06
Speaker
There's a lot about this in CDC recommendations.
00:27:09
Speaker
This is not necessarily, I mean, a given solution for everybody, but something to think as things progress.
00:27:15
Speaker
And finally, also, how do you deal with non-COVID patients
00:27:20
Speaker
And in a lot of instances where we would usually use PPE for some contact isolations, there's also a possibility of prioritizing and making sure that we're minimizing the use of PPE in other situations, which in this pandemic at this given crisis time might be less of a priority.
00:27:40
Speaker
So what about the use of PPE appropriately?
00:27:42
Speaker
And let's talk about this.
00:27:43
Speaker
And this is really, I think, what we really want to get to in terms of
00:27:48
Speaker
rational use of PPE.
00:27:51
Speaker
There are things that we need to do at triage.
00:27:53
Speaker
I think that our index of suspicion for COVID-19 as the pandemic progresses in our communities is going to be lower and lower.
00:28:01
Speaker
But anybody with acute respiratory illness of unknown origin who presents with fever or cough or shortness of breath, we definitely can have COVID.
00:28:10
Speaker
I think going further for our ED and hospitalist colleagues,
00:28:14
Speaker
Think about common diseases now like a COPD exacerbation, an asthma exacerbation, somebody who has a DKA.
00:28:21
Speaker
Why do these people usually get these?
00:28:22
Speaker
It's because they have something that exacerbated it.
00:28:25
Speaker
One of the most common causes is respiratory illness.
00:28:27
Speaker
So think about that as well.
00:28:29
Speaker
Is this DKA because I started having, I mean, a sore throat and had a fever, or is it just because I didn't take, I ran out of insulin?
00:28:36
Speaker
So all these things are going to be important and have a high index of suspicion.
00:28:40
Speaker
As soon as we suspect somebody being COVID positive, the first thing we can do is implement infection prevention control measures in all suspected patients.
00:28:49
Speaker
And that I think we should be very aggressive because it minimizes the risk of exposure for everybody else.
00:28:55
Speaker
So what are some of the infection control, prevention and control measures that we can implement immediately?
00:29:02
Speaker
So if possible, if you have anybody who you suspect or know has COVID, put a face mask on them, on the patient,
00:29:09
Speaker
that is source control.
00:29:11
Speaker
To all patients that we suspect having COVID or have COVID, apply droplet and contact precautions, and that usually means a single room with droplet and contact precautions.
00:29:24
Speaker
If possible, for those who are COVID positive or those who might undergo an aerosol-generating procedure suspected of COVID, we would use airborne precautions or negative pressure rooms.
00:29:36
Speaker
Most hospitals
00:29:37
Speaker
if they have a high influx of patients will run out of those or can run out of those.
00:29:41
Speaker
So again, the CDC recommends is to focus on droplets precautions and contact precautions, but to prioritize the use of airborne precautions for those patients at higher risk.
00:29:53
Speaker
And again, in terms of what we should use as providers in terms of N95s is again, preferred for those patients who are documented positive or those who are high aerosol generating situations and procedures
00:30:06
Speaker
such as intubation, BiPAP, bronchoscopy, and CPR.
00:30:11
Speaker
Now, so far, all the evidence or the preponderance of evidence clinically and epidemiologically would suggest that the main mode of transmission is droplets.
00:30:22
Speaker
Because of those experimental findings that can be aerosolized, I think, and because it's a novel pathogen, people have taken the extra precaution in those situations to prioritize for airborne.
00:30:34
Speaker
But I also think that we need to recognize that in many places the reality of running out of airborne rooms is true.
00:30:43
Speaker
So then you have to make decisions based on the best available evidence to try to keep everybody as safe as possible.
00:30:51
Speaker
What about, that's what we do for the patient.
00:30:53
Speaker
What about what we do ourselves as healthcare workers?
00:30:56
Speaker
I think the most important
00:30:59
Speaker
The thing I can reiterate both at home and at work is the frequent deliberate hand washing.
00:31:06
Speaker
I had opportunity to work clinically recently and it saddened me to see that there are many, many healthcare workers who don't know how to deliberately and effectively wash their hands for a situation like this.
00:31:19
Speaker
So I really think that you should really focus on this.
00:31:22
Speaker
If you're going to use water and soap, you must make sure that you cover all aspects of your hand
00:31:29
Speaker
Aspects that are often neglected are in between the fingers, the back of the index finger, the tip of the fingers, the thumbs, and you should be doing this for 20 or more seconds.
00:31:43
Speaker
So I think that if you really look at videos that we'll link in the email and you really start practicing very deliberately, you will see that in order to do a very efficient hand washing, it requires you to pay attention.
00:31:59
Speaker
And I think it's important for us to learn that, but more importantly, it's to teach it both at home and to our team, co-workers, so that everybody can stay safe.
Proper PPE Donning and Doffing
00:32:09
Speaker
If you use alcohol, you still have to cover all those areas and you should be using alcohol-based products with 60% or more alcohol for 20 to 30 seconds and then allow it to dry spontaneously.
00:32:21
Speaker
The second aspect of this is to wear the appropriate personal protective equipment.
00:32:26
Speaker
And I think that this is where
00:32:28
Speaker
we have to be very careful.
00:32:30
Speaker
I think that every time that we utilize something that is not needed, it might be something that in the near future we wish we had.
00:32:40
Speaker
And I think that people take comfort in talismans and they believe that the more they have on, the safer they are.
00:32:49
Speaker
But the reality is the way you stay safe is by understanding what each situation requires
00:32:56
Speaker
understanding how to take every step very seriously and do it the right way, and also understanding that within the context that you might be living at your individual program, there might be times where you have to make some priority decisions, and that's best made as a group, as a team for the whole institution.
00:33:16
Speaker
So let's go over this, which I think is very important, the proper order of putting on and removing personal protective equipment.
00:33:24
Speaker
So what do you need for COVID positive patients?
00:33:27
Speaker
Suspected or positive COVID patients, you should have a gown that you put on.
00:33:31
Speaker
You wash your hands first deliberately, then you put on your gown.
00:33:35
Speaker
Then if you're not going to be in a high aerosolized situation, a face mask is recommended currently by CDC and by WHO as being appropriate.
00:33:49
Speaker
You then put a face mask or goggles, and finally you put on your gloves.
00:33:54
Speaker
You take care of what you need to take care.
00:33:56
Speaker
And when you come out, this is very important, you must wash your hands in between every step.
00:34:02
Speaker
I usually will even wash the gloves with alcohol.
00:34:05
Speaker
And the reason is that that decreases the likelihood that I'll self-contaminate.
00:34:11
Speaker
I usually remove my gown and gloves together without touching the external part.
00:34:18
Speaker
I wash my hands after that.
00:34:21
Speaker
I remove my face shield or goggles.
00:34:25
Speaker
trying to not touch my face, I wash my hands again, I then remove my mask or my respirator if it was a situation where required aerosol protection, and then I wash my hands again.
00:34:38
Speaker
And I think that doing that in a paused way takes time, but I think it's very important for us to take very seriously and to show to other people how to do it.
00:34:49
Speaker
And this is very important if you're in, again, if you are in a situation
00:34:54
Speaker
In most hospitals now they're limiting the N95s to COVID positive patients and eventually that might even be limited further to COVID positive or suspected patients in which there's a high risk of aerosol, which would be the intubation, extubation, bronchoscopy.
00:35:09
Speaker
But starting to think about this in a very rational way, I think is the only way that we can optimize the availability for everybody to be as safe as possible.
00:35:19
Speaker
Now, this is actually from the WHO.
00:35:24
Speaker
and it was updated a couple days ago as of late last week.
00:35:28
Speaker
And basically what you can see here is that for healthcare facilities or inpatient facilities, they talk about what you need to do in terms of PPE for healthcare workers who are providing direct care for COVID-19 patients.
00:35:49
Speaker
So if you're not in an aerosol situation,
00:35:52
Speaker
they're recommending medical mask, gown, gloves, and eye protection.
00:35:56
Speaker
If you are in an aerosol generating procedure performed on a COVID-19 patient, they're recommending respirators, which are the N95s in the United States, plus the standard or equivalent, plus the gown, the gloves, eye protection, and the apron.
00:36:13
Speaker
So I think that this is very important for people to understand that droplets is the main way to stay safe.
00:36:20
Speaker
And perhaps the most important intervention that we can control is the hand washing and making it as deliberate as possible.
00:36:28
Speaker
But as we move forward, we might have to select who gets the, when we use the N95s.
Purpose of Masks
00:36:34
Speaker
And what's very clear from both the WHO and the CDC guidance is that when you're not working with patients, you don't need an N95.
00:36:44
Speaker
When you're not working with patients,
00:36:46
Speaker
you don't need to use a mask unless you're using that mask to protect others.
00:36:52
Speaker
And I think it's going to be something that's very important because that is only something that is used to protect others, not to protect yourself.
00:37:00
Speaker
So just remember that.
00:37:02
Speaker
And then you can see in triage, laboratory, and other areas, there is other recommendations by WHO, which are very much aligned with what CDC is saying right now.
00:37:20
Speaker
So we talked about how to minimize the use of PPE need.
00:37:24
Speaker
We talked about how to utilize the PPE we have in the best way.
00:37:29
Speaker
Let's talk a little bit about coordination of the PPE supply chain.
00:37:32
Speaker
And here I just have a couple of messages.
00:37:35
Speaker
I think that number one is we need to work with our hospital leadership.
00:37:39
Speaker
and understanding what's available, what's not available, what are they worried about, how can we optimize things?
00:37:45
Speaker
I think that sometimes there might be misalignment, but we have to be able to provide them the best information possible.
00:37:51
Speaker
And we, I think need to understand that divided house cannot succeed in this pandemic.
00:37:57
Speaker
They are doing the best they can, I'm sure, to help us.
00:38:00
Speaker
It goes beyond the hospital C-suite, it goes beyond the hospital system, it goes beyond the state, beyond the country.
00:38:07
Speaker
The impact of this pandemic is worldwide.
00:38:10
Speaker
and we're not prepared.
00:38:11
Speaker
And I think that's a reality that we need to understand.
00:38:14
Speaker
So what are the things that we can do to make sure that we utilize what we have in the best possible manner to keep all of us safe?
00:38:21
Speaker
Number two, sound physicians is working other avenues to try to secure and help with this.
00:38:27
Speaker
And we don't believe that we can solve all the problems, but I think that in as much as we can help the teams that are in most need,
00:38:35
Speaker
I think obviously that Rob, John and Jess believe that this is our obligation and we all agree.
00:38:41
Speaker
So we're working on that.
00:38:43
Speaker
And this is a reality that we must confront.
00:38:46
Speaker
I wish it were different, but it's a reality we must confront.
00:38:49
Speaker
And that's why I think knowledge is power in understanding with what I have, what are the things that would keep me
Evidence-Based PPE Usage
00:38:56
Speaker
safe?
00:38:56
Speaker
And as you see, based on the evidence,
00:38:59
Speaker
Most people want things that are not really justified by the evidence, are mostly driven by fear.
00:39:06
Speaker
But if you look at the evidence, we can apply these things the best we can and understand that no matter what, there's always something you can do to mitigate the risk of spread.
00:39:17
Speaker
The last thing I want to talk about is what happens if we do everything to optimize and we still have a crisis period where we really get into trouble.
00:39:29
Speaker
Our hope is that as we move forward and things are activated, this won't be a problem in every hospital in America.
00:39:36
Speaker
But I do believe that based on what we're hearing from New York and what has happened in other places, it could very well be a problem in hospitals that we have.
00:39:45
Speaker
So I think you need to understand how to think about this.
00:39:49
Speaker
There are conventional capacity strategies, which means that it's business as usual and you would just do whatever is recommended.
00:39:56
Speaker
And I think that that's where people were operating some months ago.
00:40:00
Speaker
There are contingent capacity strategies, which now means that we still have what we need, but we are worried that if we don't take care of it, we might run out.
00:40:08
Speaker
And I think a lot of hospitals are implementing procedures and protocols for that.
00:40:13
Speaker
And usually this means that we would do things that we normally wouldn't do.
00:40:16
Speaker
So for example, in many hospitals, they are restricting the number of N95s to prioritizing to COVID positive patients or to patients who have high aerosols.
00:40:27
Speaker
You might reutilize
00:40:29
Speaker
and then 95 the same day.
00:40:32
Speaker
In other places, you might use them for a little bit longer if you are in a place where people are cohorted.
00:40:38
Speaker
So these are things that are done in order to try to preserve N95s and are obviously less than the ideal situation, which is you use it and you throw it away, but they're done under the circumstances to provide the greatest amount of protection to our healthcare workers.
Crisis PPE Strategies
00:40:55
Speaker
And then there's also a crisis or alternate strategies
00:40:59
Speaker
which is when you're actually very close or running out.
00:41:02
Speaker
And there's also recommendations from the CDC in this respect.
00:41:07
Speaker
And the idea is that if you are rational about how you deal with a crisis, the hope is that you can go back to a conventional capacity strategy or contingent capacity strategy as soon as possible.
00:41:19
Speaker
And we're hoping with everything that's going on, that will be the case if it happens to anybody.
00:41:24
Speaker
So in terms of
00:41:26
Speaker
What do we do if we run out?
00:41:27
Speaker
Just some thoughts.
00:41:28
Speaker
Obviously, what we're trying to do is prioritize the use of PPE.
00:41:31
Speaker
So prioritize based on risk.
00:41:34
Speaker
Risk in terms of aerosolized-producing patient, not aerosolized-producing situation.
00:41:39
Speaker
That's a big differentiator.
00:41:41
Speaker
If they're not aerosolized and you don't have enough N95s, you use regular face masks and face shields, and based on the available evidence, that is going to offer you protection.
00:41:51
Speaker
Prioritize based on need.
00:41:53
Speaker
So in terms of where are the areas that you might have more of this and high risk procedures and make sure that that's where the N95s go.
00:42:05
Speaker
There's also alternatives to N95s.
00:42:07
Speaker
A lot of people have asked me about the PAPRs or the Powered Airway suits, reserves.
00:42:14
Speaker
These are actually, we're trying to get them in a lot of hospitals.
00:42:18
Speaker
They're hard to, you can't really use it all day long.
00:42:21
Speaker
I mean, it's kind of hard, but if you're in an area that's
00:42:23
Speaker
cohort that might work, but also try to use those in a judicious way for those high risk procedures and then clean them again and use them again, I think is very important.
00:42:33
Speaker
But they also offer difficulties in terms that we don't have them for everybody.
00:42:39
Speaker
They also can increase cross-contamination and they require training.
00:42:43
Speaker
So I think something to think about for the highest risk procedures and there's other alternatives that the local authorities, state authorities and governments are looking into.
00:42:52
Speaker
Another thing that I think is very important is in some situations, cohorting patients when you get to the situations and a lot of places, I mean, utilizing the same PPE for more than one patient, if they're all COVID positive, obviously, that is something that has happened in ICUs and in hospitals that have been really overrun with a number of patients.
00:43:12
Speaker
And the other thing I always think is important is to focus on steps that are available.
00:43:17
Speaker
So even if you didn't have N95s,
00:43:20
Speaker
but you could control your hand washing, do appropriate droplets, source control on the patient, minimize the time you spend with a patient and minimize the time others spend with a patient.
00:43:31
Speaker
These are all things that will mitigate your risk.
00:43:33
Speaker
So always focus on what you can do, which is always something that can be done that is effective in mitigating the risk.
00:43:41
Speaker
And lastly is that as soon as you restore your supply, obviously returning to the best practice when supplies are available.
00:43:47
Speaker
So these are things that I think are hard to sometimes listen, but I think that understanding how to best approach them are a much more powerful weapon than anxiety in terms of making sure that we all get through this as best possible.
00:44:06
Speaker
This is an example from the CDC statement on crisis alternate strategies.
00:44:12
Speaker
and just showing you that no matter what the situation is, there are things that you can do in terms of keeping the distance from the patients.
00:44:18
Speaker
If you have to be close and it's not a situation where a respirator is needed, if you can cover the patient and cover yourself with face masks, that itself, I mean, is very important and can reduce risk.
00:44:30
Speaker
Also considering the use of other alternatives other than N95s for those high-risk procedures.
00:44:36
Speaker
There's what's called elastomeric, PAPRs,
00:44:40
Speaker
based on availability.
00:44:40
Speaker
So a lot of hospitals are working to secure those as well, but those are not usually something that you can buy by the thousands.
00:44:47
Speaker
So I think it would be prioritized again for the highest risk interventions and procedures.
00:44:56
Speaker
Finally, I want to talk about some special situations for healthcare workers.
Healthcare Worker Guidelines
00:45:00
Speaker
I know that I have received and Greg and Nate a lot of questions about this.
00:45:04
Speaker
I wish I had definitive answers, but let me share with you
00:45:07
Speaker
what WHO and CDC have shared, what's posted.
00:45:11
Speaker
Number one is healthcare workers who are positive for COVID-19.
00:45:14
Speaker
Obviously those patients, those healthcare workers should be quarantined.
00:45:21
Speaker
There's different procedures that are gonna be driven by state and local authorities.
00:45:26
Speaker
I think that this is different from somebody who got an exposure.
00:45:31
Speaker
So with exposure, initially people are being quarantined, but now without symptoms and self monitoring,
00:45:37
Speaker
A lot of those are allowed to come back to work with masks.
00:45:40
Speaker
With positive tests or symptoms, the initial guidance is for them to stay home so they don't infect other coworkers.
00:45:50
Speaker
Depending on what's going on in the situation, like in Italy, obviously, they're in a very different situation.
00:45:54
Speaker
That might change, but just be aware of what is going on from CDC and speak with your local health authorities.
00:46:01
Speaker
Pregnant patients in general, there's a lot of questions about this.
00:46:06
Speaker
There is no data available as of now that suggests or that demonstrates that pregnant patients are at a higher risk of contracting the disease or at a higher risk if they contract the disease of having worse outcomes.
00:46:20
Speaker
As you might remember, some of you who were through the previous pandemic, which was the H1N1 pandemic, that virus had a particular preference or had a particular impact on pregnant patients, and there were a lot of reported
00:46:36
Speaker
very severe ARDS cases in pregnant patients.
00:46:38
Speaker
We have not seen that, but the truth is that we do not know.
00:46:41
Speaker
So if this is a concern for a pregnant healthcare worker, they should talk with their clinician, they should talk with their supervisor, and there's maybe things that can be done to mitigate this, but as of now, the CDC is recommending that this is evaluated individually.
00:47:00
Speaker
In terms of immunosuppressed patients,
00:47:03
Speaker
I think that there are obviously a wide range of definitions of immunosuppression.
00:47:08
Speaker
I do believe that if you talk with transplant surgeons and cancer and doctors, oncologists, categories of severe immunosuppression that would include recipients of transplants who are in active immunosuppression, physicians getting active chemotherapy,
00:47:28
Speaker
And maybe physicians or healthcare workers who are being treated with immunomodulation therapy for rheumatoid disease or for rheumatological disease would probably fall in a special category.
00:47:42
Speaker
And those patients, those healthcare workers should talk with their physicians, but also with their directors about their concerns.
00:47:51
Speaker
Without doubt, the situation that many clinicians are facing around the world
00:47:57
Speaker
and might be facing in the United States regarding the availability of personal protective equipment and the availability to care for COVID-19 patients in the best possible way is very challenging.
00:48:09
Speaker
It is something that we have not experienced at this level ever in my recollection as a clinician and is clearly uncharted territories for most of my colleagues.
Data-Driven Pandemic Support
00:48:24
Speaker
I think it's important to stay balanced
00:48:27
Speaker
and understand that the difficulties ahead of us are significant, but that with good data or utilizing the best available data and by supporting each other, we can get through it.
00:48:42
Speaker
I hope that the conversation in this episode was helpful and I hope that everybody is doing the best they can to stay safe and make a difference on this pandemic that has affected
00:48:56
Speaker
every country and every person in the world in one way or the other.
00:49:02
Speaker
Traditionally, we talk about books and ideas at the end.
00:49:05
Speaker
I think that that is still very fitting for times like this.
00:49:10
Speaker
I introduced the episode with a quote from Viktor Frankl, and I think that a very appropriate book to read in times like this would be Viktor Frankl's Man's Search for Meaning, which is really a phenomenal account of what he endured during the Holocaust
00:49:27
Speaker
but really focused on the creation of the logos therapy or purpose-based therapy in terms of identifying what our role is in life.

I think it's obviously a very powerful read, not a light read, but I think one that would give us a lot of insight into what is going on in our world today.

Speaker
quote from that book by Viktor Frankl that says, between stimulus and response, there is a space.
00:50:04
Speaker

00:50:08
Speaker

00:50:11
Speaker
I hope that every intensivist at the bedside does the best use of that space and chooses the best response in terms of making the greatest good for the greatest amount of people.
