Author – Ritesh Ranjan: A new study from IIT Madras has highlighted a powerful and encouraging public health story from Tamil Nadu. While the COVID-19 pandemic severely disrupted healthcare systems across the world, Tamil Nadu’s emergency healthcare network appears to have not only recovered from the crisis but also improved in several important areas after the pandemic.
The study, based on eight years of ambulance registry data from Tamil Nadu’s 108 emergency response system, found that the state recorded faster ambulance response times, better emergency transfers, reduced maternal mortality and major improvements in newborn health during the post-pandemic period.
Covering data from 2017 to 2024, the research offers one of the most detailed views of maternal emergency care in India. It shows how sustained public investment in emergency medical services, maternal care and healthcare staffing can help a system become more resilient even after a major crisis.
A Large-Scale Study Based on Real Ambulance Data
The study examined real-world data from Tamil Nadu’s 108 ambulance emergency response system. This makes the research especially important because it is not limited to one hospital, one city or a small sample group. Instead, it covers all 42 districts of Tamil Nadu and a population of more than 84 million people.
Researchers analysed the period from 2017 to 2024, covering pre-pandemic years, different phases of COVID-19 and the resilient recovery period of 2023–2024. By dividing the pandemic into multiple phases, the team was able to study how emergency healthcare services changed over time instead of treating COVID-19 as one single event.
This approach helped researchers understand how the system performed during the first wave, the second wave and the recovery period. It also allowed them to compare emergency medical service performance with actual maternal and newborn health outcomes.
What the IIT Madras Study Found
The findings show that pregnancy-related emergency calls increased sharply during the pandemic. This was expected, as movement restrictions, fear of infection and pressure on hospitals affected routine healthcare access.
However, despite these challenges, Tamil Nadu’s emergency healthcare system improved several operational indicators over time. Ambulance response time, patient transfer time and hospital handoff time became more efficient after the first COVID-19 wave and remained strong through 2023–2024.
These improvements are important because emergency response time can directly affect maternal and neonatal outcomes. Faster ambulances, smoother referrals and better coordination between emergency teams and hospitals can help save lives during pregnancy-related complications.
Major Improvement in Maternal Health Outcomes
One of the most important findings of the study is the reduction in maternal mortality during the post-pandemic phase. According to the research, maternal mortality fell by 19% to 37 deaths per 100,000 live births. This is significantly lower than India’s national average of 97 deaths per 100,000 live births.
The study also found that home deliveries dropped by more than 36%. This is a positive sign because institutional deliveries are generally safer, especially when complications arise during pregnancy or childbirth.
Other maternal health indicators also improved. Miscarriages declined by 28%, while complicated vaginal births reduced by more than 19%. These figures suggest that stronger emergency care, better access to hospitals and improved maternal health programmes helped reduce risks for pregnant women.
Newborn Health Also Improved
The study also reported meaningful progress in newborn and infant health. Neonatal mortality declined by 17%, while infant mortality fell by 19% during the post-pandemic phase.
These gains suggest that Tamil Nadu’s emergency healthcare system played a major role not only in supporting mothers but also in protecting newborns. Timely ambulance services, better referrals and improved hospital coordination can make a major difference in the first hours and days of a newborn’s life.
The improvement in neonatal and infant health also points to the importance of integrated healthcare. Emergency transport alone is not enough. It must be connected with strong antenatal care, hospital readiness, trained medical staff and effective public health planning.
Why Tamil Nadu’s Model Stands Out
Tamil Nadu has long been recognised for its public health systems, and this study adds further evidence to that reputation. The state’s model stands out because it combines emergency transport, maternal care, healthcare planning and government support at scale.
The 108 ambulance network acts as a critical link between households and hospitals. For pregnant women, especially those in rural or underserved areas, this link can be life-saving. When an emergency occurs, timely transport can decide whether the patient receives care early enough.
The study suggests that Tamil Nadu’s investment in ambulance infrastructure, healthcare staffing and maternal health schemes helped reduce the impact of the pandemic and supported a strong recovery afterwards.
Public Health Investment Played a Key Role
The researchers concluded that consistent government investment helped Tamil Nadu’s health system withstand the shock of COVID-19. Ambulance infrastructure, trained staff, better coordination and maternal health programmes all contributed to improved outcomes.
The study received data support from Emergency Medical Services and the National Health Mission, Tamil Nadu, under the state Health and Family Welfare Department.
Prof. P. Kandaswamy, a retired IPS officer and Professor of Practice at IIT Madras, led the research along with Ashwin Prakash of Moody’s Analytics. According to Prof. Kandaswamy, Tamil Nadu faced severe disruptions in maternal healthcare during the pandemic, particularly during the second wave. Home deliveries increased and maternal mortality rose sharply during that period.
However, the post-pandemic recovery tells a different story. Rather than showing long-term damage, the data shows a system that adapted, recovered and improved.
A Counter-Narrative to COVID-19 Healthcare Disruption
Globally, COVID-19 is often discussed as a crisis that weakened healthcare systems. That is true in many ways. Hospitals were overwhelmed, routine care was interrupted and emergency services faced enormous pressure.
However, the IIT Madras study presents a more hopeful counter-narrative. It shows that when a healthcare system receives sustained investment and policy support, it can emerge stronger after a crisis.
This does not mean the pandemic was not damaging. Tamil Nadu also faced serious challenges, especially during the second wave. But the state’s recovery shows that strong public systems can absorb shocks and later deliver better outcomes.
Lessons for Other Indian States
Tamil Nadu’s experience offers a practical blueprint for other Indian states, especially those with higher maternal mortality rates and weaker emergency transport systems.
The key lessons are clear. States need strong ambulance networks, risk-based antenatal care, efficient referral pathways and better coordination between emergency services and hospitals. Maternal care should not function in isolation. It must be connected to emergency transport and public health planning.
The study also highlights the value of data. By using eight years of ambulance registry records, researchers were able to identify trends, measure performance and connect emergency service efficiency with health outcomes. Other states can use similar data-driven approaches to improve healthcare delivery.
Why This Study Matters
This research matters because it connects operational performance with real health outcomes. It does not only ask whether ambulances arrived faster. It also looks at whether mothers and newborns benefited from a stronger emergency care system.
For policymakers, this is valuable evidence. It shows that investments in emergency medical services are not only useful during disasters but can continue to improve healthcare outcomes long after a crisis has passed.
The researchers also caution that the study shows strong associations rather than direct causation. This means more long-term research will be needed to fully understand all contributing factors. Even so, the findings strongly suggest that consistent investment in emergency healthcare and maternal services can produce transformative results.
Conclusion
The IIT Madras study on Tamil Nadu’s emergency healthcare system offers an important message for India’s public health future. COVID-19 created severe disruption, but Tamil Nadu’s response shows that strong systems can recover, adapt and improve.
With faster ambulance response, lower maternal mortality, fewer home deliveries and better newborn health outcomes, Tamil Nadu has demonstrated the value of sustained public investment in healthcare.
For other states, the lesson is clear: resilient healthcare systems are not built overnight. They require planning, funding, trained personnel, reliable emergency transport and strong public health programmes. When these elements come together, the results can save lives and create a stronger future for mothers and children.
