Correct Answer: C. District
The district is the principal administrative unit for health service delivery and public health planning in India. This is established under the National Health Mission (NHM) and the three-tier system of healthcare (primary, secondary, tertiary). The district serves as the nodal agency for coordinating all health programmes, disease surveillance, immunization drives, maternal and child health services, and communicable disease control under the RNTCP, NTEP, and other vertical programmes. The District Health Officer (DHO) and District Programme Manager (DPM) oversee implementation of national health policies at the grassroots level. While villages form the grassroots unit and states are the apex administrative bodies, the district acts as the critical intermediary that translates national guidelines into actionable local health interventions. This is why district-level data forms the basis for health indices, disease burden assessment, and resource allocation in India's public health system. The district also hosts the District Hospital, which serves as the secondary care referral centre for multiple Primary Health Centres (PHCs) and Community Health Centres (CHCs).
Why the other options are wrong
A. Village — While the village is the grassroots unit where health workers (ASHA, ANM) directly serve the population, it is not the principal administrative unit. Villages lack the administrative infrastructure, budget allocation authority, and coordination capacity needed to manage district-wide health programmes. Villages are served by PHCs, not the other way around. B. Centre — A 'centre' is not a recognized administrative tier in India's health system. This term may refer to health centres (PHCs, CHCs) or vaccination centres, but these are facilities, not administrative units. NBE may use this as a distractor for students confusing facility-level operations with administrative hierarchy. D. State — The state is the apex administrative body responsible for policy formulation, budget allocation, and oversight of all health programmes. However, it is too broad to serve as the principal unit of administration for day-to-day health service delivery and programme implementation. The district acts as the operational intermediary between state policy and village-level execution.
High-Yield Facts
- District is the principal administrative unit for health service delivery under the National Health Mission (NHM) framework in India.
- The District Health Officer (DHO) and District Programme Manager (DPM) are responsible for coordinating all health programmes, surveillance, and disease control at the district level.
- The three-tier system (Primary → Secondary → Tertiary) is organized at the district level, with the District Hospital serving as the secondary care referral centre.
- District-level data forms the basis for health indices, disease burden assessment, and resource allocation in India's public health system.
- The district coordinates implementation of national programmes including RNTCP, NTEP, NRHM, immunization, and maternal-child health services.
Mnemonics
PSM Hierarchy: VCD Village (grassroots execution) → Centre/CHC (facility) → District (principal admin unit) → State (apex). Remember: District is the 'sweet spot' where policy meets practice. District = DHO's Domain District Health Officer manages the district as the principal unit. If you see 'DHO' in a question, the answer is almost always district.
NBE Trap
NBE may pair "village" with "grassroots" to lure students into thinking the smallest unit is the principal administrative unit. The trap is confusing operational grassroots presence (village) with administrative authority (district).
Clinical Pearl
In Indian public health practice, when a disease outbreak occurs in a village, the ASHA/ANM reports to the PHC, which escalates to the District Surveillance Officer. The district then coordinates the response, allocates resources, and reports to the state. This real-world workflow underscores why the district is the principal administrative unit, not the village.
