Which functional capacity best distinguishes a Community Health Centre (CHC) from a Primary Health Centre (PHC) in India's tiered health system?

Explanation

## Functional Distinction: CHC vs PHC ### Specialist vs Primary Care Threshold **Key Point:** The **availability of specialist doctors and operative obstetric care (emergency caesarean section)** is the defining functional feature that elevates a CHC above a PHC. ### Comparative Table | Feature | Primary Health Centre (PHC) | Community Health Centre (CHC) | | --- | --- | --- | | **Specialist staff** | None; only generalist ANM/MPW | Obstetrician, Paediatrician, Surgeon, Physician | | **Operative obstetric care** | Delivery (normal) only; no surgery | Emergency caesarean section, laparotomy, trauma surgery | | **Inpatient beds** | 4–6 beds (maternity, general) | 30–50 beds (obstetrics, paediatrics, general, surgery) | | **Laboratory** | Basic (microscopy, blood/urine) | Comprehensive (biochemistry, haematology, microbiology) | | **Imaging** | None or basic X-ray | X-ray, ultrasound, ECG | | **Referral role** | First-contact curative care; refers to CHC | Secondary care hub; refers to tertiary centre | | **Population coverage** | 10,000–20,000 (plain); 4,000–10,000 (hilly) | 80,000–120,000 (plain); 40,000–80,000 (hilly) | | **Obstetric capability** | Antenatal care, normal delivery, postnatal care | **Emergency obstetric care (EmOC):** caesarean, blood transfusion, antibiotics | ### High-Yield Concept **High-Yield:** The CHC is defined as the **first point of secondary care** with **operative obstetric capability**. This is critical for: - **Maternal mortality reduction:** Emergency caesarean section for obstructed labour, eclampsia, placental abruption - **Neonatal emergency care:** Resuscitation, NICU-level support - **Surgical emergencies:** Acute abdomen, trauma, appendicitis **Mnemonic: CHC = **C**aesarean + **S**pecialist + **S**econdary** (the 3 S's of CHC identity) ### Clinical Pearl **Clinical Pearl:** In India's health system hierarchy, the PHC is the **primary care gatekeeper** (diagnosis and simple treatment); the CHC is the **secondary care hub** (specialist diagnosis and operative intervention). The presence of a surgeon and obstetrician at the CHC is non-negotiable for rural maternal and child health outcomes. [cite:Park 26e Ch 3]
