This is what Haitians call indecent poverty, which would suggest,
of course, that they have a clear notion, or at least a notion,
of what descent poverty might look like. The floor on your house
is not dirt, its cement. In descent poverty the roof of your house
is not thatch, it’s tin. And I have to say when I went to
Haiti 20 years ago, I didn’t know there was a distinction,
but immediately when you’re there it makes obvious sense.
And so I practice medicine mostly between these two very distinct,
it’s like the Hayes Adam Hotel and the Cheap Ride. It’s
the Brigham women’s Hospital, which is one of the giant teaching
hospitals here, and the hospital that we’ve built at the middle
of a squatter settlement in rural Haiti. And many people have actually
derided us for trying to build a medical center in the middle of
a squatter settlement saying that it seems like a very unwise use
of resources.
But interestingly, those critiques have not come from the Haitians,
but from people like you or me. So we decided early on that we would
actually listen to the people living there in indecent poverty,
and ask them what they really want. And have been following of course
also evidence based medicine and what we knew to be a set of clear
priorities in public health, but also listening to what people what.
This is the starting point in indecent poverty.
These images I’m going to show you are more targeted towards
the non-medical people here, but the impact of our administration
using modern medicine in a very poor part of the poorest country
in the Western hemisphere can be very dramatic indeed. This is a
child with extra pulmonary tuberculosis, and for the infectious
diseases people here, this is a person with tuberculosis peritonitis
and which really went undiagnosed for some time. And this is the
same patient with four months of a series of drugs that cost about
50-60 cents a day. I am convinced that very much generic problems
of what it means to be a human today, in a world that is driven
by social inequalities. And that’s what’s obsessed me
over the last 20 years going as an American to Haiti in 1983.
The two examples I’m going to use, one is arcane and the other
is well known, the arcane one just very briefly, and I presented
this in a more drawn out fashions to my medical colleagues already,
this is also a woman also with tuberculosis, but she on the other
hand could not be treated with 50 cents a day. This is a woman with
a kind of tuberculosis that’s resistant to conventional therapy
of the disease, which is now very inexpensive. So to treat her costs
a lot of money and so she, this was actually in a hospital room
not in Haiti, but in a slum in Lima, Peru. And as an aside, her
son who had been caring for her, her young adult son, later fell
ill with the same disease because its an airborne disease. She had
what’s called in our circle multi-drug resistant tuberculosis,
but had been declared untreatable because the medications were too
expensive and because its complex to deliver medications with toxities
and side effects, etc. And just to give you an idea about how straight
forward this message was, and this is from the World Health Organization
speaking about the disease that is obviously killing this women,
the comment made here is: “MDR-TB is to expensive to treat
in poor countries,” and then there’s a semi-colon in
this sentence, a complex sentence, and it even says something else,
and “ treating it detracts attention away from the real task
at hand.” Again, this is going to strike the non-medical people
as jargon, but the point is perfectly generic. It’s not about
infectious disease only, certainly managing the patients and treating
them correctly is a job for a specialist, whether infectious disease
or pulmonary specialist, but this is a general problem. You see
here two claims, 1) that is too expensive, and the other, that it
is not a good idea because it will distract our attention from what
we should really be doing. Now interestingly, this is what I call
a conversation stopper, and you can tell in reading, the intentions
of those who wrote and disseminated this wildly, they’re not
saying “okay lets stop and figure out how to bring down the
prices of the drug,” nor are they saying “lets find
a way so that we can do this without distracting attention from
the more straight forward job.” This is a comment that’s
designed to stop a conversation. Again, my argument here today is
that, in a general audience, is that this is a general problem in
the world today.
Now,
very rapidly so we can go on to the other more well known example.
This is a group of young people from the same slum who we, as you
can see, I was younger then, I had more hair, who in 1996 we trained
these young people to try and help us care for these patients with
the drugs that they needed. If the infecting strain, that is the
kind of TB that was infecting them, was resistant to some drugs,
that didn't mean that it was resistant to all drugs, and it of course
wasn't. Finding the right drug, and doing the right thing for these
patients, which is to treat them correctly, the patients who had
been told that they were untreatable, actually it turned out that
they weren't untreatable. We started doing this August 1996 and
this is inside a slum dwelling in Lima. We began treating a small
number of patients, which has now become a huge number of patients,
with results that surprise everybody. These results were published
in the New England Journal of Medicine. The uncureable patients
had an 83% cure rate. That led us to say "well, what is really
behind this problem," and the point that was behind the problem
is, of course, again, social inequality is the basics, and then
a long list of problems which I will give you a more vivid example;
one which is already known, and that is HIV.
We moved this (picture of someone coughing) forward ore rapidly
because it is an air born disease. You get TB when someone sneezes
or coughs. Having double standards of care, whether you live in
a Peruvian slum or in Charlottesville, it doesn't end up working
out that way. For example, it's true that the Bronx has a very different
per capita income than Manhattan, however, why didn't it work when
the same disease became epidemic in New York. To say, "well,
we treat it in Manhattan because its cost effective there, but unfortunately
it's not cost effective to treat it in the Bronx." Now that
would seem absurd, but that is of course, the claim that is being
made and unfortunately these pathogens do not respect national borders.
If you look, as we did, in the public literature we readily found
cases that originated in Peru but were diagnosed in affluent settings
in North America and Europe. This was just looking at the published
literature, this was not calling friends on the phone and saying
"hey, have you had any multi-drug resistant cases of TB from
Peru," because I've done that too and found that the whole
thing, would be red, the map, would be completely red.
So
what about a non-air borne disease? Before I close, this is of course
in Russia, as you may know. This story is told in this new book,
how our group got dragged into not a poor unindustrialized country
but an industrialized country that was going through very dramatic
political and economic changes, and had, as you might imagine, an
epidemic of TB. You might not know that it was drug resistant TB.
Again, how long was it before there would be patients, who unlike
the people stuck in these slums in Latin America, who got on a plane
in Europe and ended up staying in the United States with active
pulmonary multi-drug resistant TB? And the answer was, already,
it had already happened. We had found a case of a person from the
former Soviet Union who boarded a plane, I think it was Belgium,
and ended up in a state called Pennsylvania, who was sick with a
strain resistant to 8 drugs. And of course, this is going to happen
again and again. 85% of all Vermont's TB cases are among the foreign
born, but this was a case of active TB on a plane, which of course
has very different implications that we can talk about if people
are interested.
The general point, though, is that social inequalities are not only
driving forward the epidemics, I would argue, and one could make
complex arguments about this, which is what some of my research
is about: how does that work. Because it sounds easy to say that
social inequalities drive forward epidemics but it's actually quite
complex, and as you might imagine, there is a very different set
of mechanisms when you are looking at an airborne pathogen, versus
a sexually transmitted pathogen, versus a an insect born pathogen.
But social inequalities get their way into the body in a host of
ways that are important.
Now let me move forward to the second example. Now I wont spent
time talking about epidimiology or numbers. HIV, as people in this
room already know, has become the leading infectious cause of adult
death in the world today, and has surpassed all other pathogens
it seems, including the plague in the 14th century according to
body count. This is the big plague of our time, HIV, 14 million
children in Africa orphaned by the disease. You can imagine the
kind of social disruption that's going to cause. The impact on life
expectancy is what you might expect: dramatic decline in life expectancy
and complete reversal of the gains of modern public health and medicine
in the space of as single generation, in fact, in a single decade.
These are not projections, they were made as projections some time
ago, but these are from an article published a few months ago in
the British Medical Journal. These are no longer projections, but
they are just as bad or worse as predicted.
So
what is to be done? There are a lot of things that can be done.
I'll just mention that I'm an infectious disease doctor, so there
are a fairly clear set of instructions in a way for me. And I'll
show you a very similar (graph), look at the shape of these curves,
and this is a very similar shape curve, but is the opposite curve.
This is not a decline in life expectancy, this might as well a decline
in death expectancy. So something important happened in this country
in the mid 90's, and that was, of course, the development of effective
therapies. Not ideal, not therapies that eradicate the organisms,
but therapies that turn HIV from a death sentence to a chronic and
manageable disease. So those two curves remind us of what underpins
different differential chances of survival in the world today, and
those are largely social inequalities.
And
what can be done? Well let me just, again, I'm seeking here today
to focus on the general, and argue that this should be of interest
to anyone whether one is a law student, or medical student, or professor
of medicine, or philosophy professor, or an undergraduate, or community
health worker, whatever. The only point I'll make about these is
that they were both published again very recently last summer, and
they make some very curiously specific claims. These are the abstracts
of two papers published in another intellectual journal, the Lancet,
especially in international medicine. It says, well, it's 28 more
times more cost effective to prevent than to treat. Now, nobody
is going to be prefer to treat a debilitating illness than to prevent
it. Having spent a lot of my adult life as a physician working in
HIV prevention, especially with young people, I can assure you that
there's nothing fun, even with the tools, with managing a chronic
infectious disease. If there are diabetics in the room who have
to take insulin every day, they know what I'm talking about. this
is difficult, of course mostly difficult for patients, but difficult
for physicians as well.
Now remember this claim here, and again you see, now that I've shown
you this other slide about multi-drug resistant TB, I'm going to
ask you to think about these statements and ask if they're meant
to start a conversation or to stop one. When I read them, I had
the distinct impression that it was really about ending a conversation,
or delaying a conversation, and ended up asking, I was in Haiti,
when these were published and I asked a research assistant in Harvard,
to look how they found the data, how they determined that curiously
specific number. I found that one, they had two sources of data,
one was a mathematical modeling project done with a computer, not
from actually having tried and costed this out, and the other was
projected expenses for a project that was being planned for a country
in Western Africa.
Now, last summer, of course, we've been doing this for some years,
so we had real data, we had our own experience. Even without knowing
what the source of the data was, you'd have to argue that it's not
wise to make such confident claims. There are reasons to be humble
about it. First of all, the cost of the drugs and other inputs are
changing rapidly. And let me speed this up and show you what's happened.
First of all, this is a protease inhibitor, and this was a study
done by the Pan-American Health Organization in 2001. Notice the
highest price for this particular drug is in the poorest country.
Now again, I would argue that that is not a very scientific or sensible
way to approach a problem like this. The most HIV infected country,
which, again, not accidentally, is the poorest one, is the country
in which the drug costs the most in the open market. So, already
before looking at what could happen, you see what's happening and
it just doesn't make sense.
And here is our own experience. Average wholesale prices on the
market here ranging about $10,000 per patient per year, the regiments
that are being discussed are named here but I'm not going to cover
them because I'm sure not all of you here are interested. Again,
the general point is that the average wholesale price is about $10,000
dollars. We, by last year, PIHSUS Partners in Health had reduced
the price through a variety of mechanisms, which we can discuss
if people are interested, to under $700 dollars for these same two
very effective regiments. And this year, from the International
Dispensary Association, we just got our first shipments of drugs
costing under $1 dollar a day. So again, to make a claim with this
very sharp specificity, 28 times more expensive to do one thing
over the other, is not a very wise thing to do.
Now, even if it is wise or not, you can imagine that patients might
feel strongly about these matters. That's one thing that doctors
and anthropologists get to do, is they get to talk to patients and
I'm going to let you hear what some of these patients have to say
about this by quoting them. But how could we respond? Well first
of all, it's hard to do research across these steep international
gradients when we're using first world diagnostics or research endeavors,
but the very much third world therapeutic endeavors. And this is
of course a big debate in medical literature now, about 10 years
after it became a big debate in the afflicted communities themselves.
That's a common I can make wearing more my anthropology hat, because
I actually did a lot of my Ph.D. thesis talking to Haitians about
what they thought about this, and got a whole book full of commentary
in the late 1980's. Now its in our literature, but it was in their
public discussion long before it was in our scientific literature.
The point is, and this is not a criticism of research and policy
makers, I'm involved in both of these communities: both the research
community and the policy making community. We're asking a different
set of questions. We're asking if these services are sustainable,
are they appropriate technology, are they ranking priority, which
are important questions to ask, and they're going to be questions
we have to keep asking. However, we mustn't expect the patients
and their families to be asking these questions. They aren't asking
questions like that at all, and I'm sure it's obvious that they're
asking a very different set of questions and asking for a very different
set of responses. So, we ended up trying to treat this disease in
the middle of one of the poorest parts of Haiti and we ended up
calling our effort the HIV Equity Initiative, and this is going
back to 1998, by the way, which is a significant point because by
accident, we ended up becoming one of the oldest so called demonstration
projects in the resource absent, as one of my colleagues here said,
resource absent world. That was not our goal, our goal was, as you
can imagine, to remmiediate inequality to access to care, save lives
and prevent death. Prevent children from becoming orphans. But the
very short story is that it relies not only on the doctors and nurses,
who are also absent from rural Haiti, but rather on community health
workers. So here's a community health worker who is visiting a patient
every day, to give the life saving triple therapy.
And just a couple words about what happened when we made the decision
in 1998 which was a very painful one because we didn't have the
resources, and why didn't we have the resources? Because, we couldn’t'
find backers. And why would they not back us? Because, the argument
was that this was not appropriate technology or sustainable in a
community as poor as this one. So we ended up relying on, you would
be amazed on the sources of the medications. First of all, people
had been supporting us on the other project that I mentioned, the
multi-drug resistant TB project, so private donors, people who I
respectfully call church ladies. Interestingly enough, patients
in the US who collected for us, HIV patients, who collected for
us un-expired medications when their regiments changed. That of
course is no way to run a project, we did not want to run our project
like that. We needed to have security so that we would know there
would be no drug stock-outs. But in 1999 we were able to change
the fates of many.
The
people who got the regiments who lived in the __, call them group
A, and the reason this was not intended as a research project, is
just that in Group A we put the sickest patients we were sure needed
these medications right away. This is not what might be called in
certain fields cherry picking, we didn't choose patients that we
thought would do well, on the contrary, we chose patients that were
sickest and put them on therapy. Group B were from the same communities
here we had community health workers and could in principle deliver
the regiments in the manner that we chose, which was through community
health workers with daily home visits, just like we treat TB. And
Group C, These are patients all of whom received free care whenever
they showed up in our clinic, our HIV clinic, but they didn't live
near us so we couldn’t' be sure when they would show up. And
to put it mildly, the different in outcomes by 2002 was nothing
short of startling. First of all, none of the first 100, and we
call this dot hard directly observed therapy with highly active
anti-retroviral, and none of the patients died, or have died of
the first 100. And now, this is some many years later, whereas 11%
of those who received aggressive community based care with everything
but anti-retroviral, they still did much better then you would expect,
but they did not do anywhere near as well as those who received
the anti-retroviral. And this red one keeps on going up as I find
more data (bar graph), because we counted as everyone that we couldn’t'
find of the first 100 patients as alive until we could show that
they were not alive when we found them. Since I made this slide
for the retrovirus meetings in February in Boston, I can tell you
now in March that number is now 28% and not 24%, and this is again,
not surprising but it is one of the first time that it has been
documented in a country as poor as Haiti, maybe the first time.
Now, again, back to generics. No pun intended for those of you who
follow the debate about drugs. What about the argument that stigma
around HIV will prevent us from using these regiments in places
like Haiti or Southern Africa, as we may say in scholarly terms,
poppycock. Not only is there no evidence to support that often heard
claim, we have patients telling us just the opposite, and look why.
This is a man (picture of emaciated Haitian) who the day he started
anti-retroviral therapy, and the same fellow about a year and a
half later (picture of same man, healthy looking) and this is a
translation of his comments made in an interview when we were talking
about how these drugs had affected his life. And we have lots of
these stories, they are just stories. This is a woman dying in the
summer of 1999 in her home, and the same woman 2 years later who
is now an HIV outreach worker with our clinic. And she says the
medicines are eloquent enough. And they are eloquent, and their
impact in settings like Haiti if they are used correctly is of course
very dramatic.
Another example is a woman who came in weighing 73lbs with decimated
TB and HIV, and the same woman 8 months later giving a speech about
the importance of access to care. The speech of the patients, which
is actually called the Declaration of Courage is available in the
PIH web site, its been translated from Haitian into French, English
and Spanish.
In
any case, I want these to serve as points of discussions about these
inequalities so I'm going to go back to the generalities. This is
what's happening in Haiti. You know, we hear a lot about corruption
and violence in Haiti, but this is the real violence, is the violence
of a shrinking economy. What is called in both of these books structural
violence. People who wake up in the morning, and as one woman said
to me, it's the same fight every day for food, wood and water. This
is a struggle very different from the one that we face. Certainly,
a guy like me is filling a gap. This is too small to see, but the
country, it's interesting that in Latin America the country with
the most doctors per population and the country with the least are
the two neighboring islands of Cuba and Haiti.
I like
my work, I'm filling in a gap, I'm glad to be an infectious disease
doctor in a place that has a lot of infectious diseases, but the
bigger problems are not going to be fixed by people like me who
are filling in a gap. It's not the basic problem. The basic problem
is this one (graph), and I'm never sure that this image is very
decipherable, but it’s a way of looking at what's happening
in the world. This is a doctors eye view, but I think its probably
true for many other, even law or other disciplines, I think it's
probably true even generically. We're discovering great new things,
particularly in temples of learning like this one, you're making
scientific discovery, we're making advances, but we don't have a
good plan to make sure that these discoveries are used equitably,
to say nothing of having a plan to make sure that they are used
where they are needed most. So we have what you might call a growing
outcome gap in the world today. I believe that human progress will
go forward, and much of it will come from places like this one,
but we need, very much I believe, a strategy to move resources where
they need to go. To do that you need much broader based alliances,
you need people, as they say, of all walks of life to do that.
