A 35-year-old woman from a rural village in Madhya Pradesh presents to the Primary Health Centre (PHC) with complaints of persistent cough for 3 weeks and low-grade fever. The health worker at the sub-centre had referred her to the PHC for further evaluation. On examination, she is afebrile now, with a respiratory rate of 18/min. Chest examination reveals crackles in the right upper lobe. The PHC has limited diagnostic facilities and no radiography. The health worker asks the PHC nurse about the appropriate next step in managing this patient according to primary health care principles. Which of the following best represents the action aligned with the core principles of primary health care in this scenario?

Explanation

## Primary Health Care Principles in TB Management **Key Point:** Primary health care emphasizes accessibility, affordability, community participation, and appropriate use of available resources. In resource-limited settings, presumptive TB diagnosis and early initiation of treatment is a cornerstone of TB control. **High-Yield:** The RNTCP (Revised National TB Control Programme) and WHO guidelines advocate for **presumptive TB case detection and early treatment initiation** at PHC level, with referral to designated TB centres for confirmation and supervised treatment. This approach: - Reduces diagnostic delay - Prevents disease progression - Reduces transmission in the community - Aligns with equity and accessibility principles **Clinical Pearl:** In a patient with clinical features suggestive of TB (chronic cough >2 weeks, fever, constitutional symptoms, and focal crackles), initiating anti-tuberculous therapy while arranging confirmatory tests (sputum microscopy, GeneXpert MTB/RIF) is the standard approach in primary care. ## Why This Approach Embodies PHC Principles | PHC Principle | Application in This Case | | --- | --- | | **Accessibility** | Treatment initiated at PHC level without waiting for advanced diagnostics | | **Affordability** | Anti-TB drugs are provided free under RNTCP | | **Equity** | Rural patient receives same standard of care as urban patient | | **Community participation** | Health worker involvement in case detection and referral | | **Appropriate technology** | Use of sputum microscopy (available at PHC) rather than expensive imaging | **Mnemonic:** **AEIOU** of PHC — Accessibility, Equity, Integrated, Outreach, Upstream prevention. This case demonstrates all five. [cite:Park 26e Ch 5]
