The Centre for Global Health Research is conducting
an incredible research program, called Million Death Study (MDS). This program
had been started 16 years ago and has been set up to document death in India
using ‘verbal autopsy’ strategies. The MDS involves in-person surveys of more
than 1 million households in India to study premature mortality from 1997 to
2013 which occurred outside the hospital. Using the verbal autopsy method, the
researchers can determine the probable causes of death in cases where there was
no medical record or formal medical attention. Families are questioned by
field-workers about the events that preceded the deaths. The narratives are
then sent to physicians to assign a probable cause of death to each case. The
data is valuable for public health experts to monitor disease and assess interventions.
That is why the CGHR will be providing the results of the Million Death Study
to governments, research agencies and the media.
Nature has published
an article
on this study which highlights the gathering of the data, the progress of the study
and of course the preliminary results on the top causes of deaths. The four
most significant causes of death for Indians aged 30-69 are vascular disease,
chronic respiratory disease, tuberculosis and cancer. However, the real value
of the MSD lies in the observed trends and differences between deaths in
hospital and in rural areas. For instance, of the deaths attributed to malaria 90%
occurred in rural areas outside of hospital or health-care facilities. These estimates
are much higher than the estimates of the WHO. The use of
verbal autopsy to gather the data has been criticized, also by the WHO, as it
is not always possible to differentiate malaria from other diseases that cause
fever symptoms. However, other
teams have also reported higher mortality rates due to malaria.
(c) CGHR: Million Death Study
The MDS was
started by Prabhat Jha, an epidemiologist at the University of Toronto, who
wanted to found more information on his grandfather’s death, who had died at
home in India. Jha went on to found the CGHR, an independent, not-for-profit organization.
