the right pattern. Again, 15 percent of the un-implemented districts are in one state
and means could be found to give special care to this state to solve its problems.
Even in the implemented districts, on an average, one third of the PHIs have not
been involved in DTP, for one reason or another. This implies that only two thirds of
the population has in reality been offered the services. If so, how can wo establish
expectations on the basis that the entire population has access to the services. And
then feel dissatisfied that the expectations have not been fulfilled?
Management wise there are some more disquieting factors. The annual targets are
being met only to the extent of fifty per cent; supervision over PHIs by DTO and his
team is also being exercised to that extent, only about 25% of DTPs have fully
trained teams posted and quite a few team members are untrained, implying that,
supervision exercised by them could not be very effective.
Unless and until the constraints are addressed diligently, the noted progress will
fail to satisfy most. It is the right time to improve management in particular and. operations in general and the progress could even be spectacular.
IUATLD PRIZES
The International Union Against Tuberculosis and Lung Diseases (IUATLD) will award four
prizes of US $ 5000 each to two young scientists or physicians working in the field of tuberculosis
and the other two awards will be for scientists or physicians whose work relates to nontuberculous respiratory diseases. For both fields, prizes will acknowledge efforts in developing and
developed countries. Applicants should have distinguished record in research, teaching or in
carrying out public health programmes directed at preventing or treating tuberculosis or other
lung diseases. Only persons under 45 years of age of the end of 1989 are eligible.
Application in English, French or Spanish including curriculum vitae and mentioning age,
attainments and important publications (with copies thereof) should reach the IUATLD
Secretariat (68 Boulevard Saint Michel, Paris 75006) directly or through the Tuberculosis
Association of India (3, Red Cross Road, New Delhi-110 001) before 31.12.89.

standard, to-DTC teams is given by NTI.
Programme activities are standardised and made
available in the form of manuals by NTI. It is the
responsibility of DTO & his team in DTC, to
involve all peripheral health institutions (PHI) in
the district, in offering DTP services to the
people, either as microscopy or as referring

supervise their working, for NTP. Besides, there
is provision for State and Central level
programme monitoring, and supervision of the
performance of DTP, from State level, and of
State programmes from the Centre., Within the
above fairly comprehensive structuring, there is
scope for flexibility to suit local conditions, as
long as basic principles are observed. This is
necessary because under the constitution, Health
, is a State subject and all responsibility for
programme implementation and evaluation rests
! with states. An agreed quantum of central
i__ assistance (which includes international aid)
flows to state governments and provides the;
modicum of uniformity on a countrywide basis.
NTI has been monitoring NTP quarterly since
1978. This presentation, therefore, is based on
U those periodic reviews, a recent in-depth study
done by an independent voluntary agency and the
experience of those associated with NTP since its
birth.
Extension of National Tuberculosis Programme
In the nineteen fifties, the approximately 400
million people were spread in roughly 300
districts. Average district population then was L5
million - 80% rural - and number of PHIs around
50, besides the DTC. Since then, the population
has grown to over 800 million. And due to socio
-political reasons, the number of districts has gone
/-J up to 437;. average district population to 1.8
nillion and average number of PHIs to 60, with
improvement in the health infrastructure.
By 1988 end, out of 437 districts, only 371
(85%) had DTP. But at no time since 1962 has
the proportion of implemented districts crossed
the 85% level, nor has the proportion been
improving for many years. Analysis of the 66 non
implemented districts in 16 states/union
territories reveals a mixed bag of reasons, largely
of administrative nature.

Nonetheless, why should a proportion of the
population not have access to services near their
homes, so long after the introduction of DTP in
the country? And, for that matter, how many
PHIs in the implemented districts are not
participating in DTP?
In the 371 implemented districts at the end of
1988, around 14,000 PHIs were participating i.e.
on an average 38 out of the estimated 60 PHIs in
each district (63%). It appears that for

Treatment and Case Holding
Information on these aspects is comparatively
incomplete. During 1988, on an average 4,700
tuberculosis patients per DTP were put on
treatment. Of the 4,000 newly discovered cases
during the year, around 5% did not start
treatment (initial default), while 25% got added
on account of ‘transfers in’ and ‘restarted
treatment’. Only about 30% of DTPs reported
cohort analysis, according to which only 27% had
completed twelve monthly drug collections or
more.- Default in drug collections is frequentmore in urban arcas-and taking of defaulter
actions infrequent. Sputum examination at the:
end of treatment completion is infrequent too,
making any observation on sputum conversion
unrealistic.
Since no appreciable improvement in
treatment completion occurred after 1981, and
the potential for treatment completion with
standard regimens, in an NTI operational study,
was no better than 45%, it was decided, in 1985,
to try out six-month short course chemotherapy,
despite some doubts regarding the capability of
present day DTP case-holding. Eighteen DTPs in
the South were placed under supervision of the
Tuberculosis Research Centre, Madras for this
purpose. Treatment completion, on an average,
has improved to 52% with the six-month drug
regimens. And, another group of 176 DTPs have
been assigned to NTI to see if short course
chemotherapy will give similar results under the
routine supervision of DTC teams. Since
treatment compliance with the standard drug
regimens, at the sixth month of therapy, is also
around 50% to 60%, it is believed that case
holding and treatment completion can be
improved to around sixty percent level, under
