Under the NPCDCS framework in India, which is the most common non-communicable disease for which screening and early detection activities are currently being scaled up at the primary health centre level?

Explanation

## NPCDCS Screening Priorities at PHC Level **Key Point:** Hypertension is the most common NCD targeted for screening and early detection at the PHC level under NPCDCS because of its high prevalence, asymptomatic nature, and critical role as a modifiable risk factor for CVD and stroke. ### Epidemiological Justification | Disease | Prevalence in India | Screening Priority | PHC Feasibility | | --- | --- | --- | --- | | **Hypertension** | 25–30% of adults | **Highest** | **Yes** — simple BP measurement | | Type 2 DM | 8–10% of adults | High | Requires blood glucose testing | | Breast cancer | ~2 per 100,000 | Moderate | Requires trained personnel | | COPD | 3–5% of adults | Moderate | Requires spirometry | **High-Yield:** NPCDCS prioritizes hypertension screening because: 1. Highest prevalence among the four NCDs 2. Asymptomatic in 90% of cases — requires active screening 3. Simple, low-cost detection (BP cuff) 4. Effective pharmacological and lifestyle interventions exist 5. Prevents downstream complications (MI, stroke, kidney disease) ### NPCDCS Hypertension Screening Algorithm at PHC ```mermaid flowchart TD A[All adults ≥30 years at PHC]:::outcome --> B[Measure BP]:::action B --> C{BP ≥140/90 mmHg?}:::decision C -->|Yes| D[Repeat on 2 more visits]:::action D --> E{Confirmed HTN?}:::decision E -->|Yes| F[Initiate treatment + lifestyle]:::action E -->|No| G[Routine follow-up]:::outcome C -->|No| G F --> H[Referral if complications]:::action ``` **Clinical Pearl:** The NPCDCS uses the "opportunistic screening" model at PHCs — every adult attending for any reason is offered BP measurement, making hypertension detection a routine, scalable intervention. ### Why Hypertension Over Other Diseases - **Prevalence:** 25–30% vs. 8–10% (DM), 2% (cancer), 3–5% (COPD) - **Detectability:** Requires only a sphygmomanometer; no lab infrastructure needed - **Treatability:** Highly responsive to both pharmacological and non-pharmacological interventions - **Impact:** Prevents 50% of stroke deaths and 30% of MI deaths if controlled **Mnemonic:** **HYPE** — Hypertension is the **H**ighest priority, **Y**ields maximum benefit, **P**erfectly feasible at PHC, **E**asily detected.
