No. of India’s TB patients may be double the estimate: Lancet
India's tuberculosis nightmare
could be much worse than feared. A new study analysing the sale of anti-TB
medicines across India has estimated that there could be two times more
drug-sensitive TB patients than currently assumed.
While it was assumed that India's annual
burden of TB cases stands at roughly 2.2 million a year, the study to be
published in The Lancet Infectious Diseases journal on Thursday pegs this
number at over 3.8 million in 2014. This excludes drug-resistant TB cases. The
study, jointly done by the Indian government, the Imperial College of London
and the Bill & Melinda Gates Foundation, confirmed what has long been
suspected: more Indian TB patients seek treatment in the private sector than
the public sector.
Dr Sunil Khaparde,
who heads the Central TB Division and is an author of the Lancet study, said,
"We realised the number of patients coming to the private sector were
underestimated, but the new study looked at medicine sales and found that this
number alone could be as high as 2.2 million as against the 8 lakh we had
previously estimated."
It translates into a three times jump in the number of cases
in the private sector. The study's main author Dr Nimalan Arinaminpathy, who is
from the School of Public Health at Imperial College, said, "TB is a major
global health issue, and India bears a large proportion of the world's TB
burden." In fact, it is estimated that India accounts for a fourth of all
TB cases.
"The private
healthcare sector is a major issue in controlling India's TB epidemic, but so
far we haven't had a clear idea of the size of the problem: how many patients
are being treated in the private healthcare sector, and how does this compare
with the public sector? We have so far relied largely on informed opinion, but
in this study we aimed to address this question through quantitative
data," he said.
Using data of drug sales collected by IMS Health, he found
that India's TB burden in 2014 was 3.8 million instead of 2.2 million. Santacruz-based
private practitioner Dr Yatin Dholakia said the fact that India has a higher
burden of TB is an "open secret". In a study published in the Indian
Journal of Tuberculosis in 2004, Dr Dholakia had found that "in just one
Mumbai ward of Andheri," for the 94 cases registered with the government
programme, there were 363 cases in laboratories and radiology centres.
