1. The Big Data Revolution
in Healthcare
BASED ON A TED TALK BY JOEL SELANIKIO

2. Collecting global health data is an imperfect
science: Workers tramp through villages to
knock on doors and ask questions, write the
answers on paper forms, then input the
data — and from this messy, gappy
information, countries and NGOs need to
make huge decisions.

3. Data collected in form of forms

4. There have been sea change in collecting health data in
the past decade — starting with the PalmPilot and
Hotmail, and now moving into the cloud.

5. There's a concept that people
talk about nowadays called
"big data. But the biggest
problem is: how do we
organize all that information?

6. Problems while working in global
health…
The data that would help solve the problems people are trying to
solve is not actually present on the Internet, so the following
problems are faced:
• How many people right now are being affected by disasters or by
conflict situations, is not known.
• Any of the clinics in the developing world, which ones have
medicines and which ones don't, is not known.
• How many children were born, is not known.

7. Problems while working in global
health…
• Don't know how many kids died last week.
• Don't know the needs of the elderly, the mentally ill.
For all of these different critically important problems or critically
important areas that we want to solve problems in, we basically
know nothing at all.

8. Reason?
Part of the reason why data scientists don't know anything at
all is that the information technology systems that we use in
global health to find the data to solve these problems is a paper
form.

9. Reason?
The only way we can actually find out how many children were
vaccinated in the country of Indonesia, what percentage were
vaccinated, is actually not on the Internet, but by going out and
knocking on doors, sometimes tens of thousands of
doors. Sometimes it takes months to even years to do something
like this.

10. Insights

11. The problem, of course, with all
the collection of data is that
instead of using internet, paper
forms are used for survey.
The time which is wasted in
collecting data on form, then
typing it manually, and then
start analyzing, can be saved if
we directly collect data via
digital devices.

12. Relevance to an Indian
Manager?

13. • India is country with huge population. This comes with a
responsibility of collecting “huge” amount of data. And the dat
collected is useful only when it is correct.
• To manage this whole process a good manager is required, who
can ensure the proper collection of data.
