Health Systems in India

Direct answer
Rural healthcare in India stands on a three-tier pyramid — one sub-centre per 5,000 population (3,000 in hilly and tribal areas), one primary health centre per 30,000 (20,000 hilly), and one community health centre per 1,20,000 (80,000 hilly) — financed and steered since 2005 by the National Health Mission and capped since 2018 by Ayushman Bharat's twin pillars: Ayushman Arogya Mandirs delivering comprehensive primary care, and PM-JAY, the world's largest government-funded health insurance scheme covering hospitalisation up to 5 lakh rupees per family per year for the bottom two-fifths of the population.
What you must remember
- Population norms (plains versus hilly or tribal): sub-centre 5,000 versus 3,000; PHC 30,000 versus 20,000; CHC 1,20,000 versus 80,000 — the CHC is a 30-bed first referral unit with four specialists.
- ASHA (accredited social health activist): a village woman volunteer per 1,000 population; each sub-centre has at least one auxiliary nurse midwife.
- National Rural Health Mission 2005 became the National Health Mission in 2013 by merging the National Urban Health Mission; urban PHCs serve roughly 50,000 population each.
- Ayushman Bharat (2018) has two arms: Ayushman Arogya Mandir (the renamed health and wellness centre, 1.5 lakh target) staffed by a community health officer delivering comprehensive primary care; and PM-JAY, 5 lakh rupees per family per year for secondary and tertiary hospitalisation to about 10.74 crore poor families, portable across India and since 2024 covering all citizens aged 70 and above.
- The community health officer at the Arogya Mandir (BSc nursing or Ayurveda practitioner) provides expanded care including NCD screening and teleconsultation through eSanjeevani, the national telemedicine service.
- National Health Policy 2017: public health spending of 2.5% of GDP by 2025, reduced out-of-pocket spending (still nearly half the total), life expectancy 70 by 2025, IMR 28 and MMR 100.
- Current headline indicators: IMR 28 (SRS 2020), MMR 97 (SRS 2018-20), TFR about 2.0, life expectancy near 70; the Ayushman Bharat Digital Mission (2021) adds the ABHA health ID and interoperable records.
- Indian Public Health Standards (IPHS) define staffing, services and quality benchmarks for each tier, first issued 2007 and revised since.
The referral ladder from hamlet to district hospital
A farm labourer with chest pain begins at home, where ASHA calls the 108 ambulance. At the sub-centre the ANM records an ECG and gives aspirin under teleconsultation with the community health officer at the Ayushman Arogya Mandir, who reviews the tracing over eSanjeevani. Suspected acute coronary syndrome climbs the ladder: the PHC stabilises; the CHC, as first referral unit with monitoring and blood storage, manages uncomplicated cases; a STEMI with complications goes to the district hospital or an empanelled private hospital under PM-JAY, where 5 lakh rupees of coverage absorbs the angioplasty cost that would otherwise pauperise the family. At discharge, the referral ladder runs in reverse: the case sheet travels back down to the Arogya Mandir, where the CHO now manages his blood pressure, cardiac rehabilitation counselling and follow-up ECGs. The system works only because each tier knows exactly what the tier above and below it does — that division of labour is the entire syllabus of health systems.
Schemes and years students mix up
Three pairings cause the most marks lost. NRHM (2005, rural) versus NHM (2013, rural plus urban) — stems dated 2007 answer NRHM. Health and wellness centres versus PM-JAY: the first delivers primary care and NCD screening at the doorstep; the second pays for hospitalisation. ASHA versus ANM versus CHO: ASHA is an honorary community activist (1,000 population), ANM a government nurse at the sub-centre, CHO a mid-level provider at the Arogya Mandir — a stem describing "an honorary female worker who mobilises the community" answers ASHA, never ANM. Numbers to keep current: IMR 28 and MMR 97 (with survey years), the 2.5%-of-GDP NHP 2017 target, and the 5 lakh rupee cover. Remember the norms as ratios: one CHC equals about four PHCs, roughly 20 sub-centres.
Frequently asked questions
What are the population norms for a sub-centre, PHC and CHC?
Sub-centre: 5,000 (3,000 hilly or tribal); PHC: 30,000 (20,000); CHC: 1,20,000 (80,000) — with the CHC serving as a 30-bed first referral unit staffed by four specialists.
What are the two components of Ayushman Bharat?
Ayushman Arogya Mandirs (health and wellness centres) delivering comprehensive primary healthcare through community health officers, and Pradhan Mantri Jan Arogya Yojana, which funds secondary and tertiary hospitalisation up to 5 lakh rupees per family per year for eligible families.
What does the National Health Policy 2017 target?
Public health spending of 2.5% of GDP by 2025, reduction of out-of-pocket expenditure, life expectancy of 70 years by 2025, and mortality milestones including IMR 28 and MMR 100.
What is eSanjeevani?
India's national telemedicine service linking health and wellness centres with specialist doctors, so the community health officer can consult a district physician without the patient travelling.
Who is a community health officer and where is one posted?
A mid-level provider — typically BSc nursing or Ayurveda trained — posted at an Ayushman Arogya Mandir to deliver an expanded package of primary care, including NCD screening, basic laboratory tests and teleconsultation.
