Excess deaths in Tamil Nadu over four times official COVID-19 tally

But undercount is decrease than that of Madhya Pradesh and Andhra Pradesh.

The variety of “excess deaths” registered by the Civil Registration System (CRS) in Tamil Nadu ever because the COVID-19 pandemic hit (from April 2020 to May 2021) is 6.2 times the official reported determine of 24,232 deaths. But in information accessed by The Hindu, the CRS recorded the variety of deaths resulting from COVID-19 as 35,807 (14,652 in 2020 and 21,155 until May 2021), presumably adjusted over the months, a rise of practically 47% in the deaths reported in the State well being bulletin.

After omitting deaths resulting from causal components unrelated to COVID-19, it’s estimated that there have been 1,61,581 extra deaths amounting to an undercount issue of 4.5 for the pandemic interval — April 2020 to May 2021. In the second wave (April and May 2021) alone, the CRS registered 20,158 COVID-19 deaths, however we discovered that this was undercounted by an element of three, because the estimated extra deaths for this era had been 60,773. The undercount issue for 2021 was 3.7.


Excess deaths in Tamil Nadu had been calculated primarily based on the month-wise variety of deaths registered by the CRS from January 2018 to May 2021, apart from utilising year-wise information from 2015.

Data accessed by The Hindu included cause-wise deaths registered in the CRS and medically licensed deaths information (near 45% of deaths had been medically licensed in the State as of newest information from 2019).

Causes comparable to coronary heart illness and coronary heart assaults, diabetes mellitus, unclassified, liver illness, bronchitis, pneumonia, cerebro-vascular points constituted greater than 80% of all deaths registered in 2020 and 2021, rising from 72% and 73% in 2018 and 2019, suggesting that there was a fall in different causes general in comparison with COVID-related or comparable causality. Deaths resulting from most cancers for instance fell from 3% in 2018 and 2019 to 2.6% and 1.9% in 2020 and 2021 up to now. The incapability to entry commonplace take care of continual circumstances over a interval of two years, it’s suspected, might have led to increased mortality over this era amongst sufferers who had co-morbidities.

Gender ratio

Gender-wise, the proportion for female and male individuals among the many lifeless remained the identical (60%-40%) earlier than (2018 and 2019) and in the course of the pandemic years (2020 and 2021).

Both the undercount figures, adjusted for unrelated causal components and registered demise depend (3.7, 3) and unadjusted (6.5, 5.3) numbers, for 2021 and the second wave (April 2021-May 2021) respectively are, nonetheless, a lot lower than the corresponding figures from CRS information estimated for Madhya Pradesh and Andhra Pradesh (42 and 43, 34 and 31.4) not too long ago. The unadjusted determine for Tamil Nadu was additionally much like that of Karnataka — an estimated 5 times the precise demise depend for 2021. But these figures had been nonetheless increased than the undercount estimated by the WHO for COVID-19 deaths globally — two to a few times and greater than 1.6 times for the U.S., Latin America and Europe in 2020.

Raw information from the Greater Chennai Corporation on deaths present that the undercount components (primarily based on official deaths and never CRS adjusted figures) had been 5.6, 4.1, 5.6 in comparison with 6.5, 6.2 and 5.3 for the State for the durations April 2020-May 2021, January to May 2021 and April-May 2021 respectively. This means that undercounting was decrease in town limits general, however enhancements in registration in the remainder of the State led to comparable numbers in the course of the second wave.

Excess demise calculations had been not too long ago estimated for Madhya Pradesh and Andhra Pradesh (Scroll), Karnataka (The Newsminute) primarily based on CRS information and deaths registered in municipal companies in Hyderabad, Kolkata and Chennai (The Hindu) not too long ago.

The inclusion of causal information together with the CRS registrations in Tamil Nadu helped in estimating the surplus deaths in a granular method. Releasing CRS information on demise registrations together with causal components nation-wide from all States will go a great distance in estimating the precise variety of deaths as a result of pandemic in the nation and measure the true influence of COVID-19.

Differences of opinion

“We need to understand that there are two different things at play — death certification, and medical certification of death. As far as registration of deaths, there is no major issue in the State. As far as medical certification goes, it is indeed an evolving process — driven by ICMR guidelines. But in many cases there have been differences of opinion about the underlying cause of death. For instance, doctors are conflicted whether a person had died due to complications from Parkinsonism, and has also tested positive for COVID-19. So medical certification is an evolving process, at best — guidelines are also shifting,” explains Health Secretary J. Radhakrishnan.

However, he provides that Tamil Nadu has a longtime mechanism of facilitating demise audit, and a State-level reconciliation committee constituted for the specific objective of reconciling demise information (COVID-related). “The government has been clear about revealing the proper figures — whether it is related to deaths or positive cases. Reconciliation has been an important part, we even indicate such deaths in the daily bulletin we put out. In the field, health staff have also been overwhelmed, which might result in a lag in counting/certifying deaths,” Dr. Radhakrishnan stated.
