On August 8, 2000 the
Ministry of Health and Family Welfare and its nodal agency for managing the AIDS programme
the National AIDS Control Organisation (NACO) criticised the Joint United
Nations Programme on HIV/AIDS (UNAIDS) for what it says are "exaggerated"
figures of HIV-infected people in the country. With increasing pressure from the
parliament, the then health minister, C P Thakur accused UN agencies of mis-reporting
facts and creating confusion. "I am at a loss to understand how there can be so many
different estimates by different UN agencies," an anguished Thakur told reporters at
a press conference. Thakur said the NACO, which is supervised by his ministry, generates
epidemiological data from field studies and it would be "advisable" for UN
agencies to use these figures.
The government's main objection was to the
figures in the latest UNAIDS report on the global HIV/AIDS epidemic, which show that
310,000 Indians died of AIDS in India in 1999. However, the report did not explain the
source of the figure. Six years earlier, NACO had officially questioned the basis on which
UNAIDS calculated that India then had 1.75 million people infected with the AIDS virus.
Explaining how UNAIDS arrived at the figure for the number of Indians who died of AIDS in
1999, Gordon Alexander, a senior UNAIDS official in India said. "We arrived at the
number of 3.1 million using an internationally accepted model based on experience in
various parts of the world." However, because there are huge differences in the
assumed parameters, to begin with, the idea of extrapolating and applying different basal
conditions in 'universal models' to a 'specific country' is questionable. The numbers that
thus would be arrived at would be unreliable. According to Alexander, while there was room
for discussion on the figures, the idea was to "emphasise the need for prevention and
support and a care system for HIV patients."
Official Indian estimates for the year put
the number of AIDS deaths to a modest 11,000, though some experts have questioned the
reliability of this figure too. The health minister admitted that these were projections.
"We have to develop a proper model for estimation of AIDS deaths based on the number
of infections in the country," he said. "It is not always easy to get actual
reports on deaths as the cause of death is always recorded as due to opportunistic
infections like tuberculosis, meningitis, pneumonia etc."
About the number of estimated cases of
AIDS, NACO said that there were as many as 3.5 million reported HIV infection cases in the
country. However, NACO's former director Prasada Rao denied that figure and attributed it
to a "typographical error." If India did have the hundred of thousands of
HIV-infected people as estimated, there should have been many more cases of people
afflicted with diseases that mark the final phase of full-blown AIDS. Rao said there was
no evidence of this happening anywhere in India.
Some public health groups have an
explanation for the confusion over AIDS statistics. According to Purshottaman Mullolli of
the Joint Action Council (JAC), the "conflicting statistics" could be
"attributed to... a deep conspiracy to inflate figures in order to justify the
expending of all too readily available loans from the World Bank." An umbrella group
of NGOs working in the areas of human rights and HIV, the JAC has campaigned against a
NACO programme that targets so-called high-risk groups, leading to their social
ostracisation. "The fact is that far from alleviating problems, a scare is being
created in the country," he said. This has led to the import of expensive
AIDS-related medical equipment even as basic health services in the country are starved of
essential supplies, he added.
Two years after this episode, NACO, UNAIDS,
and host of other programmes that run in the country still lack information on the number
of people that suffer from AIDS in India. NACO has proposed to strengthen its annual
National Sentinel Surveillance Survey by including sexually transmitted disease clinics,
antenatal clinics, intravenous drug users sites and homosexual sites.
Earlier this year, the health ministry said
there were 3.97 million people infected with the virus that could lead to AIDS. The
figures, derived from a report by the ministrys Sentinel Surveillance Survey, said
the spread of the virus had been contained. However a report released by the Futures Group
International for USAID says the cumulative new HIV cases for 2000-2025 in India range
from 30 million (mild epidemic) to 140 million (severe epidemic).3 Health minister
Shatrughan Sinha has been quick to dismiss such figures. Especially with more funds coming
in from the Bill and Melinda Gates Foundation giving NGOs more reasons to rev up their
strident attack.
Statistics is a weapon in political battles
over social problems like AIDS. Advocates take different positions and use numbers to make
their points. It is common to hear a debate with contradictory statements
"Its a big problem!," "No, its not!". The debate
continues.
Cancer
Yet another compelling evidence of how the government plays with statistics is seen in the
data on cancer released by Indian Council for Medical Research (ICMR) in November 2001.
The National Cancer Control Programme (NCCP) says that 700,000 new cases of cancer are
detected each year and around 300,000 people die. It predicts that more than 1.4 million
people will be suffering from cancer by the year 2026, listing environmental conditions as
one of the most important reasons of the prevalence of cancer in the present era. In 1965,
the K N Rao Cancer Assessment Committee had recommended the establishment of a National
Cancer Registry Programme (NRCP), which would provide the mortality and morbidity data and
help study the distribution of cancer in different parts of India. It was only in 1972, 17
years after its recommendation that NRCP was set up. There are two main types of cancer
registries in the country the Population Based Cancer Registry (PBCR) that provides
information about the disease in an area and the Hospital Based Cancer Registry (HBCR)
that provides information about the stage at which the patient enlists in a hospital and
the treatment that is administered. It would be safe to assume that the data available on
cancer would be updated, concise and precise. Unfortunately that is not the case. The last
report that was released from the ICMR's stable was in 1992 and it contained 13-year-old
data.
This kind of data is certainly not in a
position to aid the government in devising prevention strategies.4 The ICMR cancer
registry suggests that cancer is rising in India, but the capacity of health facilities in
government hospitals is sufficient to meet the increasing numbers. If this is so, then why
is it that the number private cancer hospitals have increased from 11 in 1990 to 42 in
2001?5
Death, birth and other things
Roughly, how many people die in India every year? The Registrar General of India that
documents the numbers of deaths in hospitals or those reported to municipal offices
provides the only authentic record. Unreported deaths never make it to the final list. Yet
figures for death and birth rates are projected and guesstimates and calculated based on
decadal averages. The number of actual deaths in epidemics is not known.
Often people themselves over- report deaths
and disease. An interesting anecdote has been mentioned in P Sainaths seminal book, Everybody
loves a good drought. In a village called Bansajal, in Sarguja district of
Chattisgarh, the total number of deaths from all causes was eight as against the reported
figure of 25. On being questioned, the sarpanch (village head) responded,
"Unless we have news of people dying like flies, we dont get a single hand
pump". In the absence of actual data, this kind of tactics brings relief but shifts
the focus from the real problem.6
System Error
The Ministry of Statistics and Programme Implementation (MOSPI) is responsible for
gathering data from the grassroots and compiling them for various ministries. The Central
Statistical Organisation (CSO) coordinates and lays down norms and standards for
statistics and data collection. It also provides grants to various non-governmental
organisations for undertaking research and surveys. The National Statistical Survey
Organisation (NSSO) conducts economic census surveys. The NSSO has a specialised Survey
Design and Research Division (SDRD) and a Field Operations Division (FOD).7
At the national level, the Central Bureau
of Health Intelligence (CBHI), under the Directorate General of Health Services (DGHS),
within the Ministry of Health and Family Welfare, is the sole organisation, which deals
with the collection, compilation, analysis and dissemination of the information on health
conditions in the country. It covers various aspects of health including health status,
health resources, utilisation of the health facilities etc. It produces the Health
Information of India, a compilation of data from the Registrar Generals Offices,
NSO, NFHS, CSO, and reproductive and child health surveys. Apart from these inputs, it
compiles reports that it has received on various diseases and health infrastructure
figures from the states. The main problem with the Health Information of India is
that all it only presents is data from government hospitals. Private hospitals that cater
to 60 per cent of Indias urban demands and about 40 per cent of the rural needs are
not covered. Though private hospitals need to report epidemics and outbreaks of at least
16 notifiable diseases under the state law, very few outbreaks are ever reported by
private hospitals. These diseases include tuberculosis, cholera, diarrhoea, malaria,
rabies and other infectious and communicable diseases. In Mumbai city for example, when
leptospirosis broke out in 2000 and 2001, patients went first to private clinics, which
had never encountered a case of the disease earlier. As a result they treated patients for
malaria, which led to many deaths. Had the municipal body been notified of this, an
epidemic could have been prevented.

How
solid is the statistical support for research reports, news items, or political
assertions? Often, not. Here are a few tips on how to cut through the numerical fog. While
reading statistics ask questions and look out for conscious biases.
Questions to ask while reading statistics
Things to watch out for while reading statistics
- Are the questions being asked
- relevant?
- Is the source of data reliable?
- Is all the data reported?
- Is the data presented in context and interpreted correctly?
- Are accepted statistical procedures and techniques employed?

Although every ministry and department and
their specialised agencies collect data, very little meaningful data on the overall
picture exists. The problem in Indias statistical system is a combination of data
frauds, poor statistical knowledge and lack of political will to report the true picture.
The crux of the problem is that data is called for only when new programmes are being
proposed and old ones renegotiated. Since most programmes like malaria, tuberculosis
and AIDS have either been there for too long or are assured sustained funding, there is
little or no pressure from decision-makers for acquiring good quality data that would
reflect ground realities. Also statisticians have not evolved methods to correlate trends
between demographic, social, health and environment variables. Paying attention to details
in statistics and understanding actually what is being written could help in understanding
them better (see box: Clearing the numerical fog).
In all states, at least 24 registers are maintained by a
sub-centre (the smallest health unit in a district). For the grassroots workers the
rigmarole of reporting the same data to different authorities in different sections and
departments takes its toll. Hence there is a lot of parallel reporting of the same data.
Often these grassroots workers are not even informed of project status. In some cases
reports continue to come into state offices even though the programme has ended many years
ago. In Maharashtra, the state health officials noticed this problem and in the early
1990s devised a comprehensive 16 page format for the sub-centre to report to the district
and state office. |
