Defining Cost-Effectiveness - Smart Spending Saves
- Cost-Effectiveness Analysis (CEA): Compares intervention costs & health outcomes (QALYs, life-years).
- Goal: Maximize health per Rupee spent; not just cheapest.
- Indian Context: Crucial for India: resource limits, high OOP spending.
- Key Metrics:
- ICER (Incremental Cost-Effectiveness Ratio): $ICER = \frac{(Cost_{new} - Cost_{std})}{(Effect_{new} - Effect_{std})}$. Extra cost per unit health gain.
- QALY (Quality-Adjusted Life Year): 1 QALY = 1 year perfect health.
- DALY (Disability-Adjusted Life Year): Years lost (death/disability).
- WHO Thresholds (vs. GDP/capita):
- Highly cost-effective: ICER < 1x GDP
- Cost-effective: ICER 1x - 3x GDP
- Not cost-effective: ICER > 3x GDP
⭐ CEA guides resource allocation for max population health, vital in LMICs like India.
Economic Evaluation Tools - Crunching Care Costs
| Tool | Cost Unit | Outcome Unit | Key Metric / Formula | Decision Rule (Example) |
|---|---|---|---|---|
| CMA (Cost-Minimization) | Monetary (₹) | Assumed Identical | Lowest Cost | Choose cheapest if outcomes same |
| CEA (Cost-Effectiveness) | Monetary (₹) | Natural (e.g., LYG, cases cured) | $ICER = \frac{\Delta Cost}{\Delta Effect}$ | ICER < WTP threshold |
| CUA (Cost-Utility) | Monetary (₹) | QALYs, DALYs | Cost per QALY/DALY | Cost/QALY < WTP (e.g., 1-3x GDP/capita) |
| CBA (Cost-Benefit) | Monetary (₹) | Monetary (₹) | Net Benefit ($B-C$); $B/C Ratio$ | $B-C > \textbf{0}$; $B/C > \textbf{1}$ |
Prudent Prescribing & Testing - Lean Medicine Moves
- Prescribing Principles for Value:
- Generic substitution: Bioequivalent, offers significant ↓cost.
- Rational Drug Use (RDU): Adhere to Standard Treatment Guidelines (STGs), National List of Essential Medicines (NLEM).
- Combat polypharmacy: Conduct regular medication reviews, especially in elderly.
- Antibiotic stewardship: Crucial for ↓resistance, ↓overall healthcare expenditure.
- Lean Diagnostic Strategies:
- "Choosing Wisely" India: Critically evaluate necessity of each test/procedure.
- Stepwise, targeted investigations: Avoid broad "shotgun" approaches.
- Utilize validated clinical decision rules (CDRs) for appropriate testing.
- Discuss test implications, benefits, risks, and costs with patients.
⭐ The Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) aims to provide quality generic medicines at affordable prices through Kendra outlets.
System-Level Strategies - Bigger Picture Benefits
- National Health Policy (NHP): Aims for universal health coverage; ↑ public health expenditure to 2.5% of GDP by 2025; focus on preventive & promotive health.
- Ayushman Bharat (PM-JAY): World's largest health assurance scheme; cashless access for secondary/tertiary care hospitalisation to over 12 crore vulnerable families.
- Telemedicine & Digital Health (e.g., eSanjeevani): Enhances healthcare access, especially in remote areas; reduces travel costs & time.
- Electronic Health Records (EHRs): Improves care coordination, reduces redundant testing, supports clinical decision-making.
- Preventive & Promotive Healthcare: Emphasis on screening programs (NCDs, cancers), immunisation, health & wellness centers.
- Generic Drug Promotion: (e.g., Pradhan Mantri Bhartiya Janaushadhi Pariyojana - PMBJP) for affordable quality medicines.
- Centralized Procurement: Bulk purchasing of drugs, vaccines, and medical supplies to reduce costs.
⭐ Ayushman Bharat PM-JAY provides a health cover of ₹5 lakhs per family per year for secondary and tertiary care hospitalization across public and empanelled private hospitals in India.
High‑Yield Points - ⚡ Biggest Takeaways
- Generic drug substitution is paramount for affordable patient care.
- Evidence-Based Medicine (EBM) minimizes unnecessary tests and treatments.
- Adopt a stepwise approach to diagnosis: history, examination, then targeted investigations.
- Preventive strategies and health education are crucial for long-term cost reduction.
- Rational antibiotic stewardship combats resistance and controls expenditure.
- Appropriate referrals to specialists prevent needless costs and delays.
- Avoiding low-value care (e.g., routine screening without indication) is essential.
