Emergency Care Needs to Be Prioritised
Syllabus: Health
Source: TH
Context: The recent stampede in Karur, Tamil Nadu, highlighted gaps in India’s emergency response system, sparking renewed calls to treat emergency medical care not merely as a service, but as a constitutional duty ensuring every citizen’s right to life.
About Emergency Care Needs to Be Prioritised:
Evolution of Emergency Care:
• Modern emergency medicine evolved from wartime trauma management during the World Wars, where organised triage and rapid evacuation became critical.
• The industrial revolution and advances in trauma and cardiovascular medicine led to structured ambulance systems with life-support capability.
• Over time, the focus expanded from mere transport to on-site stabilisation, giving rise to paramedic-led and doctor-led mobile emergency units.
• India’s 108 Emergency Response System, introduced under the National Health Mission (NHM), institutionalised public access to emergency transport.
• The concept evolved globally into the “Golden Hour” and later the “Platinum Ten Minutes”, emphasising response speed as a determinant of survival.
Constitutional Imperative:
• The Right to Life under Article 21 of the Indian Constitution inherently guarantees access to timely emergency medical care.
• The State is ethically bound to ensure unobstructed emergency access during mass gatherings and disasters.
Science of Timely Intervention:
• Acute illnesses and trauma cause rapid circulatory collapse; immediate diagnosis and treatment can reverse these life-threatening disturbances.
• The “Golden Hour” represents the crucial 60 minutes post-injury when intervention can prevent irreversible organ damage.
• The evolved “Platinum Ten Minutes” standard stresses that medical help—not just transport—should reach the victim within 10 minutes.
• Modern ambulances act as mobile ICUs, equipped with oxygen supply, defibrillators, ECG, airway management tools, and telemedicine links.
• Timely, skilled intervention transforms outcomes, reducing preventable deaths from strokes, heart attacks, and trauma.
Existing Initiatives:
• The 108 Ambulance Service, a public-private partnership, operates over 10,000 ambulances, serving 7–9 million patients annually.
• Tamil Nadu leads with an average response time of 10 minutes 14 seconds, close to the Platinum Ten benchmark.
• The National Ambulance Code (AIS-125) sets standards for design, safety, and equipment across vehicle categories.
• The Motor Vehicles (Amendment) Act, 2019, mandates right of way for ambulances and penalises obstruction.
• NHM support enables State-level flexibility in managing emergency systems and training first responders.
Challenges in Emergency Systems:
• Fragmented services: Wide disparities exist between States and private providers, leading to uneven quality.
• Skill shortage: Lack of certified emergency medical technicians and high attrition rates weaken continuity.
• Infrastructure gaps: Many ambulances lack advanced life support systems and telemedicine integration.
• Poor coordination: Weak linkages between call centres, hospitals, and ambulance teams delay response.
• Accountability vacuum: Absence of a National Emergency Regulatory Authority results in inconsistent standards and oversight.
Policy Reforms and Recommendations:
• Constitute a National Emergency Services Regulatory Authority to standardise training, operations, and equipment across States.
• Integrate technology through AI-based dispatch systems, GPS tracking, and real-time data sharing with hospitals.
• Introduce national certification and pay parity for paramedics to improve retention and professionalism.
• Expand air and drone ambulances for remote access and organ transport logistics.
• Mandate emergency access protocols for public gatherings and urban infrastructure planning.
• Promote PPP models for integrated emergency networks linking urban and rural areas.
Conclusion:
A nation capable of robotic surgeries and organ transplants must not lose lives to delayed ambulances or disorganised response systems. Emergency medical care must evolve from fragmented services into a right-based, standardised national mission. Recognising it as a constitutional and moral duty is essential to ensure that every citizen receives help when every second counts.

Context: The Commission for Air Quality Management (CAQM) invoked Stage II of the Graded Response Action Plan (GRAP) across Delhi-NCR as the city’s Air Quality Index (AQI) crossed 300 (“very poor”).
About Graded Response Action Plan (GRAP):
What it is?
• The Graded Response Action Plan (GRAP) is a statutory framework that specifies stage-wise measures to be implemented to combat deteriorating air quality in the National Capital Region. It provides predefined actions based on the severity of pollution.
Established in: GRAP was first introduced in 2017 under the directives of the Supreme Court of India and the Environment (Protection) Act, 1986.
• Later revised by the CAQM in December 2024 to include predictive action based on IMD and IITM forecasts.
Aim: The plan aims to create a graded and preemptive response system for air quality management by identifying specific interventions to be taken as the AQI worsens in Delhi-NCR.
Criteria / Stages: GRAP classifies air quality into four categories based on AQI levels and corresponding actions:
Stage | Category | AQI Range | Actions
Stage I | Poor | 201–300 | Dust control, waste removal, enforcement of vehicle norms
Stage II | Very Poor | 301–400 | Mechanical sweeping, C&D monitoring, DG set regulations
Stage III | Severe | 401–450 | Restrictions on BS-III/IV vehicles, construction limits
Stage IV | Severe+ | Above 450 | Ban on truck entry, WFH orders, halting C&D projects
Key Features of GRAP:
• Dynamic implementation: Actions are activated dynamically based on real-time AQI data and IMD/IITM forecasts, allowing authorities to respond before pollution peaks.
• Cumulative approach: Each higher stage includes all measures from lower stages, ensuring progressive tightening of restrictions as air quality worsens.
• Inter-agency coordination: Implementation involves coordinated efforts among CAQM, CPCB, SPCBs, Urban Local Bodies (ULBs), and Traffic Police, ensuring accountability at every level.
• Predictive enforcement: Measures are invoked in advance when forecasts show a likely rise in AQI, promoting preventive rather than reactive air quality management.
