A 32-year-old woman from a rural village in Madhya Pradesh attends the primary health centre (PHC) with complaints of persistent cough for 3 weeks and low-grade fever. The ANM (Auxiliary Nurse Midwife) suspects tuberculosis and refers her to the district hospital for sputum microscopy and chest X-ray. However, the patient is unable to afford transport and diagnostic costs. The PHC has a trained ASHA worker and basic microscopy facility. According to the principles of primary health care, what is the most appropriate immediate action?

Question

Accepted Answer

C. Conduct sputum microscopy at the PHC itself; if positive, initiate anti-TB treatment under DOTS and involve the ASHA worker for adherence support. ## Primary Health Care Principle: Accessibility and Decentralization

**Key Point:** Primary health care emphasizes bringing diagnostic and treatment services as close as possible to the community, reducing barriers of cost, distance, and time.

**High-Yield:** The PHC is the first point of contact in India's three-tier health system. When equipped with basic facilities (sputum microscopy) and trained personnel (ANM, ASHA), it should provide diagnosis and initiate treatment rather than defer to higher levels.

**Clinical Pearl:** Tuberculosis under the National Tuberculosis Elimination Programme (NTEP) mandates:
- Sputum microscopy at PHC/sub-centre level for case detection
- Immediate initiation of DOTS (Directly Observed Therapy, Short-course) if positive
- ASHA worker involvement for treatment adherence and reducing default rates

**Mnemonic: PHC DOTS** — Primary Health Centre is the Diagnostic and Operational Treatment Site for TB in India.

## Why Option 1 is Correct

Utilizing the PHC's existing microscopy capacity and trained staff:
1. Reduces diagnostic delay and treatment initiation time
2. Eliminates financial and transportation barriers for the patient
3. Aligns with the principle of equitable access (a core PHC principle)
4. Enables early community-based DOTS, improving cure rates and reducing transmission

## PHC Role in TB Case Management

| Function | PHC Capability | Rationale |
|----------|---|---|
| Sputum microscopy | Yes (basic facility) | Decentralized diagnosis |
| DOTS initiation | Yes (trained ANM) | Evidence-based treatment |
| Adherence monitoring | Yes (ASHA support) | Community engagement |
| Referral to district TB unit | Only if complications arise | Tiered care |

**Warning:** Delaying diagnosis or treatment violates the principle of accessibility and increases community transmission risk.
