Good morning.

I've come here to share with you an experiment
1
2000
4000
00:21
of how to get rid of one form of human suffering.
2
6000
4000
00:25
It really is a story of Dr. Venkataswamy.
3
10000
3000
00:28
His mission and his message is about the Aravind Eye Care System.
4
13000
6000
00:34
I think first it's important for us to recognize what it is to be blind.
5
19000
5000

6
24000
4000
00:43
Woman: Everywhere I went looking for work, they said no,
7
28000
4000
00:47
what use do we have for a blind woman?
8
32000
3000
00:50
I couldn't thread a needle or see the lice in my hair.
9
35000
3000
00:53
If an ant fell into my rice, I couldn't see that either.
10
38000
3000
00:57
Thulasiraj Ravilla: Becoming blind is a big part of it,
11
42000
2000
00:59
but I think it also deprives the person of their livelihood, their dignity,
12
44000
5000
01:04
their independence, and their status in the family.
13
49000
3000
01:07
So she is just one amongst the millions who are blind.
14
52000
4000
01:11
And the irony is that they don't need to be.
15
56000
3000
01:14
A simple, well-proven surgery can restore sight to millions,
16
59000
4000
01:18
and something even simpler, a pair of glasses, can make millions more see.
17
63000
5000
01:23
If we add to that the many of us here now
18
68000
3000
01:26
who are more productive because they have a pair of glasses,
19
71000
4000
01:30
then almost one in five Indians will require eye care,
20
75000
3000
01:33
a staggering 200 million people.
21
78000
3000
01:36
Today, we're reaching not even 10 percent of them.
22
81000
4000
01:40
So this is the context in which Aravind came into existence
23
85000
3000
01:43
about 30 years back
24
88000
3000
01:46
as a post-retirement project of Dr. V.
25
91000
3000
01:49
He started this with no money.
26
94000
2000
01:51
He had to mortgage all his life savings
27
96000
3000
01:54
to make a bank loan.
28
99000
2000
01:56
And over time, we have grown into a network of five hospitals,
29
101000
4000
02:00
predominately in the state of Tamil Nadu and Puducherry,
30
105000
4000
02:04
and then we added several, what we call Vision Centers
31
109000
4000
02:08
as a hub-and-spoke model.
32
113000
2000
02:10
And then more recently we started managing hospitals
33
115000
3000
02:13
in other parts of the country
34
118000
2000
02:15
and also setting up hospitals in other parts of the world as well.
35
120000
4000
02:19
The last three decades,
36
124000
2000
02:21
we have done about three-and-a-half million surgeries,
37
126000
4000
02:25
a vast majority of them for the poor people.
38
130000
4000
02:29
Now, each year we perform about 300,000 surgeries.
39
134000
4000
02:34
A typical day at Aravind, we would do about a thousand surgeries,
40
139000
4000
02:38
maybe see about 6,000 patients,
41
143000
4000
02:42
send out teams into the villages to examine, bring back patients,
42
147000
5000
02:47
lots of telemedicine consultations,
43
152000
3000
02:50
and, on top of that, do a lot of training,
44
155000
3000
02:53
both for doctors and technicians who will become the future staff of Aravind.
45
158000
6000
03:00
And then doing this day-in and day-out, and doing it well,
46
165000
4000
03:04
requires a lot of inspiration and a lot of hard work.
47
169000
4000
03:08
And I think this was possible thanks to the building blocks
48
173000
3000
03:11
put in place by Dr. V.,
49
176000
3000
03:14
a value system, an efficient delivery process,
50
179000
4000
03:18
and fostering the culture of innovation.
51
183000
3000
03:21
(Music)
52
186000
7000
03:29
Dr. V: I used to sit with the ordinary village man because I am from a village,
53
194000
4000
03:33
and suddenly you turn around and seem to be in contact with his inner being,
54
198000
4000
03:37
you seem to be one with him.
55
202000
3000
03:40
Here is a soul which has got all the simplicity of confidence.
56
205000
5000
03:45
Doctor, whatever you say, I accept it.
57
210000
3000
03:48
An implicit faith in you
58
213000
2000
03:50
and then you respond to it.
59
215000
2000
03:52
Here is an old lady who has got so much faith in me, I must do my best for her.
60
217000
3000
03:57
When we grow in spiritual consciousness,
61
222000
3000
04:00
we identify ourselves with all that is in the world,
62
225000
3000
04:03
so there is no exploitation.
63
228000
3000
04:06
It is ourselves we are helping.
64
231000
3000
04:09
It is ourselves we are healing.
65
234000
2000
04:17
(Applause)
66
242000
5000
04:23
This helped us build a very ethical and very highly patient-centric organization
67
248000
6000
04:29
and systems that support it.
68
254000
2000
04:31
But on a practical level, you also have to deliver services efficiently,
69
256000
6000
04:37
and, odd as it may seem, the inspiration came from McDonald's.
70
262000
4000
04:41
Dr. V: See, McDonald's' concept is simple.
71
266000
4000
04:45
They feel they can train people all over the world,
72
270000
8000
04:53
irrespective of different religions, cultures, all those things,
73
278000
3000
04:56
to produce a product in the same way
74
281000
4000
05:00
and deliver it in the same manner
75
285000
3000
05:03
in hundreds of places.
76
288000
2000
05:05
Larry Brilliant: He kept talking about McDonalds and hamburgers,
77
290000
2000
05:07
and none of it made any sense to us.
78
292000
6000
05:13
He wanted to create a franchise,
79
298000
3000
05:16
a mechanism of delivery of eye care
80
301000
3000
05:19
with the efficiency of McDonald's.
81
304000
3000
05:22
Dr. V: Supposing I'm able to produce eye care,
82
307000
2000
05:24
techniques, methods, all in the same way,
83
309000
4000
05:28
and make it available in every corner of the world.
84
313000
3000
05:31
The problem of blindness is gone.
85
316000
2000
05:34
TR: If you think about it, I think the eyeball is the same,
86
319000
3000
05:37
as American or African,
87
322000
2000
05:39
the problem is the same, the treatment is the same.
88
324000
3000
05:42
And yet, why should there be so much variation in quality and in service,
89
327000
4000
05:46
and that was the fundamental principle that we followed
90
331000
3000
05:49
when we designed the delivery systems.
91
334000
3000
05:52
And, of course, the challenge was that it's a huge problem,
92
337000
3000
05:55
we are talking of millions of people,
93
340000
3000
05:58
very little resource to deal with it,
94
343000
3000
06:01
and then lots of logistics and affordability issues.
95
346000
4000
06:05
And then so, one had to constantly innovate.
96
350000
3000
06:08
And one of the early innovations, which still continues,
97
353000
3000
06:11
is to create ownership in the community to the problem,
98
356000
4000
06:15
and then engage with them as a partner,
99
360000
3000
06:18
and here is one such event.
100
363000
2000
06:20
Here a community camp just organized
101
365000
3000
06:23
by the community themselves,
102
368000
3000
06:26
where they find a place, organize volunteers,
103
371000
3000
06:29
and then we'll do our part. You know, check their vision,
104
374000
4000
06:34
and then you have doctors who you find out what the problem is
105
379000
3000
06:37
and then determine what further testing should be done,
106
382000
3000
06:40
and then those tests are done by technicians
107
385000
5000
06:45
who check for glasses,
108
390000
4000
06:49
or check for glaucoma.
109
394000
4000
06:53
And then, with all these results, the doctor makes a final diagnosis,
110
398000
4000
06:57
and then prescribes a line of treatment,
111
402000
3000
07:00
and if they need a pair of glasses, they are available right there at the camp site,
112
405000
4000
07:04
usually under a tree.
113
409000
2000
07:06
But they get glasses in the frames of their choice,
114
411000
3000
07:09
and that's very important because I think glasses,
115
414000
3000
07:12
in addition to helping people see,
116
417000
2000
07:14
is also a fashion statement, and they're willing to pay for it.
117
419000
3000
07:22
So they get it in about 20 minutes
118
427000
3000
07:25
and those who require surgery, are counseled,
119
430000
3000
07:28
and then there are buses waiting,
120
433000
3000
07:31
which will transport them to the base hospital.
121
436000
3000
07:34
And if it was not for this kind of logistics and support,
122
439000
5000
07:39
many people like this would probably never get services,
123
444000
3000
07:42
and certainly not when they most need it.
124
447000
4000
07:46
They receive surgery the following day,
125
451000
4000
07:50
and then they will stay for a day or two,
126
455000
3000
07:53
and then they are put back on the buses
127
458000
2000
07:55
to be taken back to where they came from,
128
460000
3000
07:58
and where their families will be waiting to take them back home.
129
463000
4000
08:03
(Applause)
130
468000
6000
08:09
And this happens several thousand times each year.
131
474000
5000
08:14
It may sound impressive that we're seeing lots of patients,
132
479000
3000
08:17
very efficient process,
133
482000
2000
08:19
but we looked at, are we solving the problem?
134
484000
4000
08:23
We did a study, a scientifically designed process,
135
488000
2000
08:25
and then, to our dismay,
136
490000
2000
08:27
we found this was only reaching seven percent of those in need,
137
492000
5000
08:32
and we're not adequately addressing more, bigger problems.
138
497000
4000
08:36
So we had to do something different,
139
501000
2000
08:38
so we set up what we call primary eye care centers, vision centers.
140
503000
5000
08:43
These are truly paperless offices
141
508000
2000
08:45
with completely electronic medical records and so on.
142
510000
4000
08:49
They receive comprehensive eye exams.
143
514000
3000
08:52
We kind of changed the simple digital camera into a retinal camera,
144
517000
4000
08:56
and then every patient gets their teleconsultation with a doctor.
145
521000
4000
09:02
The effect of this has been that, within the first year,
146
527000
4000
09:06
we really had a 40 percent penetration in the market that it served,
147
531000
5000
09:11
which is over 50,000 people.
148
536000
2000
09:13
And the second year went up to 75 percent.
149
538000
2000
09:15
So I think we have a process by which
150
540000
2000
09:17
we can really penetrate into the market
151
542000
2000
09:19
and reach everyone who needs it,
152
544000
3000
09:22
and in this process of using technology, make sure
153
547000
3000
09:25
that most don't need to come to the base hospital.
154
550000
3000
09:28
And how much will they pay for this?
155
553000
2000
09:30
We fixed the pricing, taking into account
156
555000
3000
09:33
what they would save in bus fare in coming to a city,
157
558000
4000
09:37
so they pay about 20 rupees, and that's good for three consultations.
158
562000
4000
09:41
(Applause)
159
566000
3000
09:44
The other challenge was, how do you give high-tech
160
569000
3000
09:47
or more advanced treatment and care?
161
572000
3000
09:50
We designed a van with a VSAT,
162
575000
3000
09:53
which sends out images of patients to the base hospital
163
578000
4000
09:57
where it is diagnosed,
164
582000
3000
10:00
and then as the patient is waiting, the report goes back to the patient,
165
585000
4000
10:04
it gets printed out, the patient gets it,
166
589000
3000
10:07
and then gets a consultation about what they should be doing --
167
592000
3000
10:10
I mean, go see a doctor or come back after six months,
168
595000
3000
10:13
and then this happens as a way of
169
598000
2000
10:15
bridging the technology competence.
170
600000
3000
10:20
So the impact of all this has been essentially one of growing the market,
171
605000
4000
10:24
because it focused on the non-customer,
172
609000
3000
10:27
and then by reaching the unreached,
173
612000
3000
10:30
we're able to significantly grow the market.
174
615000
2000
10:32
The other aspect is how do you deal with this efficiently
175
617000
4000
10:36
when you have very few ophthalmologists?
176
621000
3000
10:39
So what is in this video is a surgeon operating,
177
624000
3000
10:42
and then you see on the other side,
178
627000
2000
10:44
another patient is getting ready.
179
629000
2000
10:46
So, as they finish the surgery,
180
631000
3000
10:49
they just swing the microscope over,
181
634000
3000
10:52
the tables are placed so that their distance is just right,
182
637000
4000
10:56
and then we need to do this, because, by doing this kind of process,
183
641000
3000
10:59
we're able to more than quadruple the productivity of the surgeon.
184
644000
5000
11:04
And then to support the surgeon,
185
649000
2000
11:06
we require a certain workforce.
186
651000
3000
11:09
And then we focused on village girls that we recruited,
187
654000
4000
11:13
and then they really are the backbone of the organization.
188
658000
3000
11:16
They do almost all of the skill-based routine tasks.
189
661000
4000
11:20
They do one thing at a time. They do it extremely well.
190
665000
3000
11:23
With the result we have very high productivity,
191
668000
3000
11:26
very high quality at very, very low cost.
192
671000
3000
11:31
So, putting all this together, what really happened was
193
676000
3000
11:34
the productivity of our staff was
194
679000
3000
11:37
significantly higher than anyone else.
195
682000
3000
11:40
(Applause)
196
685000
6000
11:46
This is a very busy table,
197
691000
2000
11:48
but what this really is conveying is that,
198
693000
2000
11:50
when it comes to quality, we have put in
199
695000
2000
11:52
very good quality-assurance systems.
200
697000
3000
11:55
As a result, our complications are significantly lower
201
700000
3000
11:58
than what has been reported in the United Kingdom,
202
703000
3000
12:01
and you don't see those kind of numbers very often.
203
706000
3000
12:04
(Applause)
204
709000
2000
12:06
So the final part of the puzzle is,
205
711000
2000
12:08
how do you make all this work financially,
206
713000
3000
12:11
especially when the people can't pay for it?
207
716000
3000
12:14
So what we did was, we gave away a lot of it for free,
208
719000
4000
12:18
and then those who pay, I mean, they paid local market rates,
209
723000
3000
12:21
nothing more, and often much less.
210
726000
2000
12:23
And we were helped by the market inefficiency.
211
728000
3000
12:26
I think that has been a big savior, even now.
212
731000
3000
12:29
And, of course, one needs the mindset to be wanting to give away
213
734000
4000
12:33
what you have as a surplus.
214
738000
3000
12:36
The result has been, over the years,
215
741000
2000
12:38
the expenditure has increased with volumes.
216
743000
2000
12:40
The revenues increase at a higher level,
217
745000
2000
12:42
giving us a healthy margin
218
747000
2000
12:44
while you're treating a large number of people for free.
219
749000
4000
12:48
I think in absolute terms,
220
753000
2000
12:50
last year we earned about 20-odd million dollars,
221
755000
3000
12:53
spent about 13 million, with over a 40 percent EBITA.
222
758000
5000
12:58
(Applause)
223
763000
8000
13:06
But this really requires going beyond what we do,
224
771000
3000
13:09
or what we have done,
225
774000
3000
13:12
if you really want to achieve solving this problem of blindness.
226
777000
3000
13:15
And what we did was a couple of very counter-intuitive things.
227
780000
4000
13:19
We created competition for ourselves,
228
784000
3000
13:22
and then we made eye care affordable
229
787000
3000
13:25
by making low-cost consumables.
230
790000
3000
13:28
We proactively and systematically
231
793000
3000
13:31
promoted these practices to many hospitals in India,
232
796000
4000
13:35
many in our own backyards and then in other parts of the world as well.
233
800000
3000
13:38
The impact of this has been that these hospitals,
234
803000
4000
13:42
in the second year after our consultation,
235
807000
3000
13:45
are double their output
236
810000
2000
13:47
and then achieve financial recovery as well.
237
812000
5000
13:53
The other part was how do you address
238
818000
3000
13:56
this increase in cost of technology?
239
821000
4000
14:00
There was a time when we failed to negotiate
240
825000
3000
14:03
the [intra-ocular lens] prices to be at affordable levels,
241
828000
2000
14:05
so we set up a manufacturing unit.
242
830000
4000
14:09
And then, over time, we were able to bring down the cost significantly
243
834000
4000
14:13
to about two percent of what it used to be when we started out.
244
838000
5000
14:18
Today, we believe we have about seven percent of the global market,
245
843000
4000
14:22
and they're used in about 120-odd countries.
246
847000
4000
14:26
To conclude, I mean, what we do, does it have a broader relevance,
247
851000
5000
14:31
or is it just India or developing countries?
248
856000
5000
14:36
So to address this, we studied UK versus Aravind.
249
861000
6000
14:43
What it shows is that we do roughly about 60 percent
250
868000
3000
14:46
of the volume of what the UK does,
251
871000
3000
14:49
near a half-million surgeries as a whole country.
252
874000
3000
14:52
And we do about 300,000.
253
877000
3000
14:55
And then we train about 50 ophthalmologists
254
880000
3000
14:58
against the 70 trained by them,
255
883000
3000
15:01
comparable quality, both in training and in patient care.
256
886000
3000
15:04
So we're really comparing apples to apples.
257
889000
3000
15:07
We looked at cost.
258
892000
2000
15:09
(Laughter)
259
894000
2000
15:11
(Applause)
260
896000
6000
15:17
So, I think it is simple to say
261
902000
2000
15:19
just because the U.K. isn't India the difference is happening.
262
904000
4000
15:23
I think there is more to it.
263
908000
2000
15:25
I mean, I think one has to look at other aspects as well.
264
910000
2000
15:27
Maybe there is --
265
912000
2000
15:29
the solution to the cost could be in productivity,
266
914000
4000
15:33
maybe in efficiency, in the clinical process,
267
918000
3000
15:36
or in how much they pay for the lenses or consumables,
268
921000
3000
15:39
or regulations, their defensive practice.
269
924000
3000
15:42
So, I think decoding this can probably bring
270
927000
3000
15:45
answers to most developed countries
271
930000
5000
15:50
including the U.S., and maybe
272
935000
2000
15:52
Obama's ratings can go up again.
273
937000
3000
15:55
(Laughter)
274
940000
3000
15:59
Another insight, which, again, I want to leave with you,
275
944000
4000
16:03
in conditions where the problem is very large,
276
948000
3000
16:06
which cuts across all economic strata,
277
951000
2000
16:08
where we have a good solution,
278
953000
3000
16:11
I think the process I described,
279
956000
2000
16:13
you know, productivity, quality, patient-centered care,
280
958000
4000
16:17
can give an answer,
281
962000
3000
16:20
and there are many which fit this paradigm.
282
965000
2000
16:22
You take dentistry, hearing aid, maternity and so on.
283
967000
3000
16:25
There are many where this paradigm can now play,
284
970000
3000
16:28
but I think probably one of the most challenging things
285
973000
2000
16:30
is on the softer side.
286
975000
2000
16:32
Now, how do you create compassion?
287
977000
2000
16:34
Now, how do you make people own the problem,
288
979000
2000
16:36
want to do something about it?
289
981000
2000
16:38
There are a bit harder issues.
290
983000
2000
16:40
And I'm sure people in this crowd can probably find the solutions to these.
291
985000
4000
16:44
So I want to end my talk leaving this thought and challenge to you.
292
989000
3000
16:47
Dr. V: When you grow in spiritual consciousness,
293
992000
3000
16:50
we identify with all that is in the world
294
995000
3000
16:53
so there is no exploitation.
295
998000
3000
16:56
It is ourselves we are helping.
296
1001000
2000
16:58
It is ourselves we are healing.
297
1003000
3000
17:01
TR: Thank you very much.
298
1006000
