I now have all the information needed for a comprehensive note. Here it is:
Sub-Centre
(Source: Park's Textbook of Preventive and Social Medicine)
Definition and Position
The sub-centre is the most peripheral outpost of the existing health delivery system in rural areas. It is the first contact point between the community and the formal health system, providing primary health care services at the grass-root level.
Establishment Norms
| Area | Population Coverage |
|---|
| General/Plains | 1 sub-centre per 5,000 population |
| Hilly, Tribal, Backward areas | 1 sub-centre per 3,000 population |
As of March 2017, 25,650 PHCs were working with 6 sub-centres each. One LHV (Lady Health Visitor) and one Health Assistant (Male) at the PHC are entrusted with supervision of every six sub-centres.
Indian Public Health Standards (IPHS) for Sub-Centres
IPHS for sub-centres (revised in 2012) prescribe basic promotive, preventive, and limited curative services. Services are classified as:
- Essential - minimum assured services
- Desirable - services all states/UTs should aspire to achieve
Categorization of Sub-Centres
Sub-centres have been categorized into two types based on catchment area, health-seeking behaviour, case load, and location of other facilities (PHC/CHC/FRU/Hospitals):
Type A Sub-Centre
- Provides all recommended services except conducting deliveries as a facility.
- ANMs trained in midwifery may conduct normal deliveries at home if needed.
- Applicable to sub-centres in remote, hilly, desert, or tribal areas with poor transport; or those without adequate physical infrastructure for a labour room.
- If demand for deliveries rises, the sub-centre may be upgraded to Type B.
Type B Sub-Centre (MCH Sub-Centre)
- Developed as a delivery facility.
- Also caters to adjacent Type A sub-centre areas for delivery.
- Provides full intra-natal services including: managing labour using Partograph, identification and management of danger signs during labour, and basic emergency obstetric care.
Staff / Manpower
| Staff | Sub-centre A (Essential) | Sub-centre A (Desirable) | Sub-centre B - MCH (Essential) | Sub-centre B - MCH (Desirable) |
|---|
| ANM / Health Worker (Female) | 1 | +1 | 2 | - |
| Health Worker (Male) | 1 | - | 1 | - |
| Staff Nurse (or ANM if Staff Nurse unavailable) | - | - | - | 1** |
| Safai-Karamchari* | 1 (Part-time) | - | 1 (Full-time) | - |
* To be outsourced.
** If number of deliveries at the sub-centre is 2 or more per month.
Supervisory staff (based at PHC): One LHV (Lady Health Visitor) and one Health Assistant (Male) supervise every 6 sub-centres. Medical Officer also makes periodic supervisory visits.
Site of Service Delivery
Since the sub-centre mainly provides outreach services, most services are NOT delivered in the building itself. Services are delivered at:
- Villages - during Village Health and Nutrition Day (VHND) / Immunization sessions
- During house visits
- During house-to-house surveys
- During community meetings and events
- At the facility premises - minimum 6 hours of routine OPD per day, 6 days a week (where 2 ANMs are provided, one must remain at the centre at all times)
