Primary Health Care & Health System in India

Primary Health Care (PHC) is the backbone of any health system and a perennial favourite in Community Medicine. This topic links the Alma Ata Declaration, the three-tier rural health infrastructure, population norms, and the historical committees (Bhore, Mudaliar, etc.) right up to the modern Ayushman Bharat Health & Wellness Centres. Numbers and definitions win marks here.

Definition & the Alma Ata Declaration (1978)

The International Conference on Primary Health Care was held at Alma-Ata, USSR (now Almaty, Kazakhstan) in September 1978, jointly organised by WHO and UNICEF. It gave the historic slogan "Health For All by 2000 AD" (HFA 2000).

Primary Health Care was defined as:

High-yield: "Essential health care based on practical, scientifically sound and socially acceptable methods and technology, made universally accessible to individuals and families in the community through their full participation and at a cost that the community and country can afford to maintain at every stage of their development in the spirit of self-reliance and self-determination."

Four pillars (principles) of PHC

1. Equitable distribution (social justice / coverage of all)
2. Community participation (e.g., village health guides, ASHA)
3. Inter-sectoral coordination (health depends on agriculture, education, water, housing)
4. Appropriate technology (technology that is scientifically sound + acceptable + affordable)

A useful mnemonic for the principles: "ECIA" — Equitable distribution, Community participation, Inter-sectoral coordination, Appropriate technology.

Eight Essential Elements of PHC

The Declaration listed 8 essential components. Mnemonic: "ELEMENTS" or the classic "CHE-MEN PEW" — but the most widely used is the first-letter string:

#	Element	Mnemonic letter
1	Education about prevailing health problems	E
2	Locally endemic disease control	L
3	Expanded Programme on Immunization (EPI)	E
4	Maternal & Child Health including family planning	M
5	Essential drugs provision	E
6	Nutrition (food supply & proper nutrition)	N
7	Treatment of common diseases & injuries	T
8	Safe water & basic sanitation	S

Mnemonic = "ELEMENTS" (E-L-E-M-E-N-T-S maps directly to the eight above).

High-yield: A 9th element — mental health — was added later by WHO. Original Alma Ata had 8.

Comprehensive vs Selective PHC

A favourite conceptual MCQ. After Alma Ata, the broad "comprehensive" vision was criticised as too costly and slow, leading Walsh and Warren (1979) to propose Selective PHC — targeting a few cost-effective interventions.

Feature	Comprehensive PHC	Selective PHC
Origin	Alma Ata 1978	Walsh & Warren, 1979
Approach	Address all/most health needs	A few high-impact, low-cost interventions
Philosophy	Equity, social justice, holistic	Cost-effectiveness, measurable targets
Classic package	All 8 elements	GOBI / GOBI-FFF
Criticism	Resource-intensive, slow	Vertical, ignores root causes / equity

GOBI-FFF (UNICEF's selective package):

• G – Growth monitoring
• O – Oral rehydration therapy
• B – Breastfeeding
• I – Immunization
• F – Female education
• F – Family spacing
• F – Food supplementation

The Three-Tier Rural Health Care System

India's rural health infrastructure is organised in three tiers, established largely on the recommendations of the Bhore Committee and operationalised through later plans. Each level has defined population norms (per the Indian Public Health Standards / National Health Mission).

Sub-Centre → Primary Health Centre (PHC) → Community Health Centre (CHC) is the referral pathway (peripheral → intermediate).

Population norms (single most-tested table)

Facility	Plain area	Hilly/Tribal/Difficult area
Sub-Centre (SC)	5,000	3,000
Primary Health Centre (PHC)	30,000	20,000
Community Health Centre (CHC)	1,20,000	80,000

High-yield: Memorise as 5,000 / 30,000 / 1,20,000 (plain) and 3,000 / 20,000 / 80,000 (hilly). A PHC covers roughly 6 sub-centres; a CHC covers roughly 4 PHCs.

1. Sub-Centre (SC) — the most peripheral

• The most peripheral and first contact point between the primary health care system and the community.
• Staffed by 1 Health Worker Female (ANM / Auxiliary Nurse Midwife) + 1 Health Worker Male (MPW-M); one Health Assistant supervises 6 sub-centres.
• Functions: MCH, family planning, immunization, diarrhoea control, control of communicable diseases, nutrition counselling.
• Now being upgraded to Health & Wellness Centres (HWC) led by a Community Health Officer (CHO).

2. Primary Health Centre (PHC)

• First contact point between village community and a Medical Officer (MBBS doctor).
• Concept given by the Bhore Committee (1946); established in India in 1952 through the Community Development Programme.
• Staffing: 1 Medical Officer (now often 2) + 14 paramedical/other staff.
• 4–6 beds for inpatients.
• A PHC supervises about 6 sub-centres.
• Functions: all 8 elements of PHC, plus referral and supervision.

3. Community Health Centre (CHC) — First Referral Unit (FRU)

• A 30-bedded hospital.
• Staffed by 4 specialists: Surgeon, Physician, Gynaecologist (Obstetrician), and Paediatrician, supported by 21 paramedical/other staff.
• Should have OT, labour room, X-ray, laboratory.
• Designated as a First Referral Unit (FRU) if it provides emergency obstetric care (incl. caesarean/EmOC), newborn care, and blood storage.

High-yield: CHC = 4 specialists + 30 beds. FRU must offer EmOC + newborn care + blood storage (the "3 critical services").

Historical Committees (very high-yield)

These committees are repeatedly tested. Match the year, chairman and key recommendation.

Committee	Year	Chairman	Key point
Bhore Committee (Health Survey & Development Committee)	1946	Sir Joseph Bhore	Foundation of PHC; 3-million / 3-month plan; integration of curative & preventive; "social physician"
Mudaliar Committee (Health Survey & Planning Committee)	1962	Dr. A.L. Mudaliar	Reviewed Bhore progress; strengthen district hospitals; PHC quality poor
Chadha Committee	1963	Dr. M.S. Chadha	Malaria maintenance phase; basic health worker (1 per 10,000)
Mukherjee Committee	1965	Sri Mukherjee	Separate staff for family planning
Jungalwalla Committee	1967	Dr. N. Jungalwalla	"Integrated health services"; unified cadre
Kartar Singh Committee	1973	Kartar Singh	Multipurpose worker (MPW) scheme; 1 MPW per 5,000
Shrivastav Committee	1975	Dr. J.B. Shrivastav	Village Health Guides; rural health scheme; basis of ROME scheme
Bajaj Committee	1986	Dr. J.S. Bajaj	Health manpower planning; education commission

Bhore Committee 1946 — the cornerstone

High-yield: The Bhore Committee (1946) is the foundation of India's health system and laid the blueprint for PHCs.

Key recommendations:

• Integration of preventive and curative services at all administrative levels.
• Concept of the "social physician" — a doctor oriented to community/social medicine.
• A three-tier health system.
• Long-term ("3-million plan", one primary unit per 10,000–20,000) and short-term goals.
• Short-term: one primary health unit per 40,000 population with 75 beds, 6 doctors, 6 PHNs, etc. (the "3-month plan" being the short-term proposal).
• No individual should be denied care for inability to pay.

Mudaliar Committee 1962

• Reviewed progress since Bhore; found quality of PHC care unsatisfactory.
• Recommended strengthening of district hospitals with specialists to act as central referral institutions.
• Limit PHC population to 40,000.
• Constitution of an All India Health Service.

From PHC to Health & Wellness Centres (HWC) — current architecture

Under Ayushman Bharat (launched 2018), the government created two inter-related components:

1. Health & Wellness Centres (AB-HWC) — for Comprehensive Primary Health Care (CPHC).
2. Pradhan Mantri Jan Arogya Yojana (PM-JAY) — health insurance (₹5 lakh/family/year for secondary & tertiary care).

Sub-Centres and PHCs are being upgraded/transformed into HWCs. Target: 1,50,000 HWCs.

High-yield: HWCs expand the package beyond maternal-child health to include NCDs (hypertension, diabetes, three common cancers — oral, breast, cervical), mental health, ENT, ophthalmology, geriatric and palliative care, oral health, and emergency care — the 12 packages of CPHC.

A Community Health Officer (CHO) — typically a BSc Community Health / nurse / Ayurveda practitioner with a bridge course — leads the SC-HWC.

Three-tier transformation: Sub-Centre → SC-HWC (led by CHO) and PHC → PHC-HWC (led by Medical Officer).

Levels of Health Care (conceptual)

Level	Setting	Provider
Primary care	SC, PHC, dispensaries (first contact)	MPW, ANM, GP/MO
Secondary care	CHC, district hospital	Specialists
Tertiary care	Medical colleges, regional/super-speciality hospitals	Super-specialists

Investigations / Indicators of choice

For "health system performance", remember key reference metrics often paired with PHC questions:

• Doctor : population ratio recommended by WHO = 1 : 1000.
• India's norm for a basic health worker = 1 per 5,000 (Kartar Singh).
• Village Health Sanitation & Nutrition Committee (VHSNC) and ASHA (Accredited Social Health Activist) — 1 ASHA per ~1,000 population (per habitation/village under NRHM 2005).

Management / "drug of choice" equivalent — what to deliver where

• Sub-Centre: ANC, immunization, ORS, contraceptives, basic drugs.
• PHC: MBBS-level OPD, minor procedures, referral, all 8 PHC elements.
• CHC/FRU: Specialist care, emergency obstetrics (caesarean), blood storage, in-patient care.

Complications / challenges of the system

• Shortfall of sub-centres, PHCs and CHCs against population norms (esp. in EAG states).
• Specialist vacancy at CHCs is the biggest gap (often >60–70% shortfall of surgeons/paediatricians).
• Urban primary care relatively neglected → addressed by National Urban Health Mission (NUHM, 2013).
• Vertical programmes causing duplication — the rationale for integration (Jungalwalla).

Key differentials / commonly confused pairs

• Bhore (1946) vs Mudaliar (1962): Bhore = founded the system; Mudaliar = reviewed it and strengthened district hospitals.
• PHC (the facility) vs PHC (the strategy): the Primary Health Centre is a building/institution; Primary Health Care is the Alma Ata strategy. Examiners exploit this!
• CHC vs FRU: Every FRU is a CHC-level institution, but a CHC becomes an FRU only when it offers EmOC + newborn care + blood storage.
• HFA by 2000 (Alma Ata) vs SDG-3 (2030): Alma Ata aimed for HFA by 2000; current global target is Universal Health Coverage under SDG-3.

Recently asked / exam angle

• Population covered by a sub-centre in a plain area → 5,000 (3,000 hilly). Repeatedly asked in NEET PG / INI-CET.
• Number of essential elements of PHC at Alma Ata → 8 (mental health added later as 9th).
• Year and venue of the Alma Ata Declaration → 1978, Alma-Ata (USSR/Kazakhstan).
• Which committee recommended Multipurpose Workers? → Kartar Singh (1973).
• Which committee is the foundation of PHC / recommended the social physician? → Bhore (1946).
• Number of specialists at a CHC → 4 (Surgeon, Physician, OBG, Paediatrician).
• GOBI-FFF components and Selective vs Comprehensive PHC debate.
• HWC leader / CHO and the 12 packages of comprehensive primary health care under Ayushman Bharat — newer, increasingly tested.
• First contact between community & a doctor → PHC; most peripheral contact point → Sub-Centre.
