I now have enough information from both the authoritative medical textbook (Park's Preventive and Social Medicine) and current web sources. Let me compile the comprehensive answer.

Health Care Delivery System in India

Overview

India's health care delivery system is one of the largest and most complex in the world, serving a population of over 1.4 billion across 28 states and 8 Union Territories. Under the Constitution of India, states are largely independent in the delivery of health care to their people. The Central Government's role is primarily policy-making, planning, guiding, assisting, evaluating, and coordinating with State Health Ministries. The system has 3 main structural links: Central, State, and Local/Peripheral. - Park's Textbook of Preventive and Social Medicine, p. 989

Administrative Structure

1. Central Level

The official organs of the health system at the national level are:
  • Ministry of Health and Family Welfare (MoHFW) - headed by a Cabinet Minister, with two departments: (1) Department of Health and (2) Department of Family Welfare.
  • Directorate General of Health Services (DGHS) - the principal technical adviser to the Government of India on medical and public health matters.
  • Central Council of Health and Family Welfare - an advisory body that frames broad policies.
Functions under the Union List (exclusive Central responsibility):
  1. International health relations and port quarantine administration
  2. Administration of central institutes (AIIH&PH Kolkata, NCDC Delhi, etc.)
  3. Promotion of research through research centres
  4. Regulation of medical, pharmaceutical, dental and nursing professions
  5. Establishment and maintenance of drug standards
  6. Census and collection of statistical data
  7. Coordination with states for health promotion
Functions under the Concurrent List (shared Central-State responsibility) include matters like population control, prevention and extension of infectious diseases, vital statistics, and food adulteration.

2. State Level

Each state has a Directorate of Health Services (or Director of Health and Family Welfare in some states). The Director is the chief technical adviser to the State Government on all matters relating to medicine and public health, responsible for organizing and directing all health activities. Regional Directors and Functional Directors (specialists in MCH, family planning, nutrition, TB, leprosy, health education) assist the Director.

3. District Level

The district is the principal unit of administration. India has 718 districts (2020). Each district is divided into:
  1. Sub-divisions
  2. Tahsils/Talukas (200-600 villages each)
  3. Community Development Blocks (~100 villages, population 80,000-1.2 lakh)
  4. Municipalities and Corporations
  5. Villages
  6. Panchayats

Levels of Health Care

India follows a three-tier system that provides a continuum of care from village level to apex institutions. - Park's, p. 989

Tier 1 - Primary Health Care

The first level of contact between individuals, families, and the national health system. Most health problems can be dealt with at this level. Components include:
FacilityCoverage Norm
Sub-Centre1 per 5,000 population (1 per 3,000 in hilly/tribal areas)
Primary Health Centre (PHC)1 per 30,000 population (1 per 20,000 in hilly/tribal areas)
Community Health Centre (CHC)1 per 1,20,000 population (referral centre for 4 PHCs)
Village-level workers bridge the cultural and communication gap between rural people and the organized health sector:
  • ASHA (Accredited Social Health Activist) - one per 1,000 population; a female community health worker who is the first point of contact.
  • ANM (Auxiliary Nurse Midwife) - provides MCH services at sub-centre level.
  • Anganwadi Workers - under the ICDS scheme; provide nutrition, immunization, and child development services; paid Rs. 1,500/month honorarium.
  • Trained Dais - local birth attendants trained to make deliveries safe.
Sub-Centre services include maternal and child health (antenatal care, intrapartum, postnatal), family planning, immunization, nutrition, basic curative care, communicable disease control, and referral. - Park's, p. 998

Tier 2 - Secondary Health Care

More complex problems are dealt with at this level. Secondary care is generally provided at:
  • District Hospitals - one per district, serving 500,000 to 1 million population
  • Community Health Centres (CHCs) - first referral units (FRUs), with specialist services in medicine, surgery, obstetrics, and paediatrics
Patients are referred from PHCs and CHCs to district hospitals for specialized diagnostics, surgeries, and inpatient care. - Commonwealth Fund Profile of India

Tier 3 - Tertiary Health Care

The highest and most specialized level of care, requiring specific facilities and highly specialized health workers. Institutions include:
  • Medical College Hospitals and Government Medical College Hospitals (GMCHs)
  • All India Institutes of Medical Sciences (AIIMS) - premier national institutes
  • Regional and Specialized Hospitals
  • Apex Institutions

Sectors of Health Care Delivery

India's health care is delivered through four parallel sectors:

1. Public Sector

Government-funded facilities at central, state, and local levels - from sub-centres to AIIMS. Public health care is mostly free at the point of delivery, though resource constraints limit quality and accessibility.

2. Private Sector

The largest provider of outpatient and inpatient care in India. Includes:
  • Corporate hospital chains (Apollo, Fortis, Manipal, etc.)
  • Private hospitals, polyclinics, nursing homes
  • General practitioners and individual clinics
  • Diagnostic laboratories and imaging centres Out-of-pocket payments account for approximately 44% of total health expenditure (2023), which drives catastrophic health expenditure for many households. - Commonwealth Fund, 2025

3. Indigenous Systems of Medicine (AYUSH)

  • Ayurveda - traditional Indian herbal/plant-based medicine
  • Yoga and Naturopathy
  • Unani and Tibbi - Greco-Arabic medicine
  • Siddha - traditional South Indian medicine
  • Homeopathy
AYUSH practitioners form a significant part of the health workforce, especially in rural and semi-urban areas. The Ministry of AYUSH was established in 2014 to promote and regulate these systems.

4. Voluntary Health Agencies

NGOs, charitable trusts, and community organizations that supplement government efforts in areas like tuberculosis control, leprosy, mental health, and child nutrition.

Key National Health Programmes

ProgrammeFocus
National Health Mission (NHM)Umbrella mission covering rural (NRHM) and urban (NUHM) health; strengthening primary care infrastructure
Ayushman Bharat - PM-JAYHealth insurance coverage of Rs. 5 lakh per family/year for 500 million+ beneficiaries; expanded in Sept 2024 to include all senior citizens 70+ years
Ayushman Arogya Mandirs (AAM)Upgraded Health and Wellness Centres; 1,72,148 operational as of March 2024; 1,34,650 offering 12 key services
PM Ayushman Bharat Health Infrastructure Mission (AB-HIM)Rs. 64,000 crore over 6 years for infrastructure at primary, secondary, and tertiary levels
Universal Immunization Programme (UIP)National immunization against 12 vaccine-preventable diseases
eSanjeevaniNational telemedicine platform improving access in remote areas
Nikshay (TB)Digital tracking platform for TB patients under the National TB Elimination Programme
Ayushman Bharat Digital Mission (ABDM)Unique Health ID for every citizen; digital health records ecosystem
The healthcare budget for FY 2024-25 was increased to Rs. 90,958 crore (a 2% rise), with priority given to infrastructure and maternal-child health convergence. - UPSC Medico, 2025

Challenges

Despite significant progress, the system faces persistent structural problems:
  1. Urban-rural disparity - Urban areas have far better infrastructure, specialist availability, and quality of care compared to rural and tribal regions.
  2. High out-of-pocket expenditure - At 44% of total health spend, this remains the primary driver of poverty and financial hardship.
  3. Human resource shortage - Severe shortage of doctors, nurses, and specialists, particularly in rural areas; doctor-population ratio remains below WHO norms in many states.
  4. Fragmented referral system - The three-tier referral chain is poorly utilized; patients routinely bypass primary and secondary levels and overload tertiary hospitals directly. - Commonwealth Fund, 2025
  5. Underfunding - Public health spending remains around 1.3-1.5% of GDP, well below the National Health Policy target of 2.5% of GDP.
  6. Quality gaps - Variable quality of care across facilities; IPHS (Indian Public Health Standards) compliance is incomplete.
  7. Inequity - Marginalized populations (tribal, Dalit, women, urban poor) face compounded barriers of geography, literacy, language, and affordability.

Recent Developments (2024-2026)

  • Ayushman Bharat PM-JAY expansion (September 2024): All senior citizens aged 70 and above now covered regardless of income, benefiting ~6 crore senior citizens across 4.5 crore families.
  • NHM achievements: 7,998 public health facilities certified; 4,200+ with national certification.
  • Digital health push: ABDM Unique Health IDs, eSanjeevani telemedicine, and Ni-kshay TB tracking are transforming delivery and data systems.
  • AIIMS expansion: New AIIMS campuses in multiple states have been commissioned, improving tertiary access in previously underserved regions.

Summary

India's health care delivery system is structured across three administrative tiers (Central, State, District) and three care levels (Primary, Secondary, Tertiary), delivered through public, private, AYUSH, and voluntary sectors. The public system reaches deeply into rural India through ASHAs, ANMs, sub-centres, PHCs, and CHCs. Flagship schemes like Ayushman Bharat and NHM have significantly expanded coverage and access. The core challenges - underfunding, human resource gaps, fragmented referral, and high out-of-pocket costs - remain the priorities that need structural reform for India to achieve Universal Health Coverage. - Park's Textbook of Preventive and Social Medicine
