What do we know about improving health in Punjab? And

some lessons from IndiaDr. Jeffrey Hammer

Princeton University

IGC – CDPR Seminar, IslamabadFebruary 12, 2015

What do we know? Possible answers

• First is “not a lot”

• Second is: Maybe something from India? Or from theory and logic?

• Third is: Maybe something from surveys done in Pakistan?

• Fourth is: Not really. as I undercut answer three above with examples of peculiarities in Pakistani data.

• Can we start getting some reliable data by establishing collection systems?

3

Talk in three parts

• Some evidence from rural areas in India on the relative effectiveness of public and (publicly provided) private goods.

• Some meager (and debatable) evidence on the same thing in Punjab, Pakistan

• Complaint about the state of statistics and a suggestion or two on new opportunities for data sources, collection methods and organization.

4

The Total Sanitation Campaign in Maharashtra

• Program: change behavior to get rid of open defecation, don’t just build latrines

• Evaluation: Randomized Control Trial of promotion of 100% safe defecation practices at village level.

Chaudhury, Ghosh Moulik et al; Hammer and Spears (2014)

5

Challenges of initial design

• Secretary, Rural Development, wanted to try this out in the hardest possible conditions – very poor, very isolated, heavily tribal areas.

• He bet that if it could work there, it could work anywhere.

• Unfortunately, he lost.

• Only in 1 District out of 3 (Ahmednagar) did officials do anything

6

Lessons (before we even start)

• On Intent to Treat grounds it obviously failed. Implementation constraints are critical

• BUT, on Treatment on Treated grounds, things look much better

• So, it might work. But only where it works.

So addressing sanitation (with big externalities) could work!

How about publicly provided primary health care?...

not so much

9

How can this be? How can publicly provided medical care NOT help?

• Vacancies (A budget, not an implementation problem)

• Absenteeism

• Low levels of knowledge and ability of public MBBS’s (sometimes relative to untrained – sometimes not)

• Abysmal effort exerted by public providers such that they can’t possibly find out what’s wrong with you

• Substitutability of small (ish) public sector with a much larger private sector around it

10

All leading to the question: What is the marginal impact of an expanded

public system on the market as a whole?

• On overall usage (quantity)?• On the accuracy of medical advice (quality) in

the market as a whole – public and private?

• This is a very hard problem – we can only address bits and pieces of it

11

“Weak links” in our knowledge

India

• Absenteeism – about 40% in 2003, not much change about a decade later

• Quality of care (knowledge)- Das et al, Das and Hammer – next slide

Pakistan

• ??? – one very good but small study (Hasanain et al) based on an IT intervention, not a national picture

• ??? Not that I know of

12

How bad can quality be?

Madhya Pradesh: Public doctors know more than anyone but put in so little effort, they give the worst advice and treatment

Reasons to doubt effectiveness of public sector - almost no one uses it

What shows up as possible correlates with child health in the Punjab?

• Education (of mothers for sure – maybe fathers)

• Standard of living (measured by possessions – not even a direct measurement)

• Maybe, just maybe, open defecation (but not nearly as convincing as we’d like to see)

18

Why is it so hard to show anything?

• Serious data quality issues

• “Errors in variables” larger than variance of variables

Plea for better data

• Massive changes in rich world in type, sources and sizes of available data

• Organized in ways that are either easy to use or, at least, publicly available

• Much is being organized geographically – a continuously lengthening panel of routinely collected data

22

Can we start now to develop general use statistics?

• Could we request donors to ask questions in their surveys that policy makers in Pakistan have discussed and considered important? And maybe ensure quality?

• Could we request researchers to format data so that it can be absorbed into a larger system?

• Could we request ministries to do the same?
