Regarding the roles and responsibilities of Community Health Centers (CHCs) in India's three-tier system, all of the following are true EXCEPT:

## CHC Population Coverage and Location **Key Point:** The correct population norm for CHC is: - **CHC serves approximately 120,000 population** (not 10,000) - **CHC is located at the block level** — typically one CHC per block - **10,000 population** is served by a **Sub-center** (SC), not a CHC The statement claiming "CHC serves 10,000" is **factually incorrect** and confuses the population norms across the three-tier system. ## Three-Tier System: Population Norms | Tier | Population Served | Staffing | Key Functions | |------|-------------------|----------|----------------| | **Sub-center (SC)** | 3,000–5,000 (plain); 1,000–3,000 (hilly) | 1 ANM (F) + 1 Male Health Worker | Basic preventive & promotive care | | **PHC** | 3,000–5,000 (plain); 1,000–3,000 (hilly) | 1 ANM + 1 Male Health Worker | First contact, treatment of common illnesses | | **CHC** | ~120,000 (block level) | 4 specialists + nursing staff | Referral, emergency obstetrics, surgery, pediatrics | ## CHC Core Competencies **High-Yield:** CHCs are **secondary care centers** equipped for: 1. Emergency obstetric care (cesarean sections, management of eclampsia, PPH) 2. Surgical emergencies (appendicitis, trauma, acute abdomen) 3. Pediatric emergencies (severe pneumonia, sepsis, meningitis) 4. Specialist consultation (surgery, obstetrics, pediatrics, medicine) **Clinical Pearl:** CHC is the **"first referral unit"** — it bridges primary care (PHC) and tertiary care (district hospital). ## Hierarchical Referral Flow ```mermaid flowchart TD A[Sub-center<br/>3,000-5,000 pop]:::outcome --> B[PHC<br/>3,000-5,000 pop]:::outcome B --> C[CHC<br/>~120,000 pop<br/>Block level]:::outcome C --> D[District Hospital<br/>~1 million pop]:::outcome A -->|Referral| B B -->|Referral| C C -->|Referral| D ```
