I now have all the content from K. Park's textbook. Let me craft a well-structured, exam-ready 5-mark answer.
Cost-Benefit Analysis and Cost-Effectiveness Analysis
[Source: Park's Textbook of Preventive and Social Medicine, 28th Edition, Chapter on Health Management - Quantitative Methods]
π EXAM ANSWER
COST-BENEFIT ANALYSIS AND COST-EFFECTIVE ANALYSIS
(Quantitative Methods in Health Management)
Definition / Introduction:
Cost-benefit analysis and cost-effective analysis are quantitative management techniques derived from the field of economics, operations research, and budgeting that are used for rational decision-making in health service management.
1. COST-BENEFIT ANALYSIS (CBA)
"This is a management technique which has attracted the widest attention for application in the health field."
- K. Park, Textbook of Preventive and Social Medicine
Definition:
Cost-benefit analysis is a technique in which the economic benefits of any programme are compared with the cost of that programme.
Key features:
| Feature | Details |
|---|
| Expression of benefits | In monetary terms (Rs./currency) |
| Purpose | To determine if a programme is economically sound |
| Comparison | Multiple alternate programmes can be compared |
| Outcome | Best programme is selected based on benefit-to-cost ratio |
Formula concept:
Benefit-to-Cost Ratio (BCR) = Total Benefits (in money) / Total Cost
- BCR > 1 β Programme is economically viable
- Higher BCR β More preferred programme
Drawback of CBA:
"The main drawback with this technique is that the benefits in the health field, as a result of a particular programme, cannot always be expressed in monetary terms."
- Benefits in health are usually expressed as:
- Births prevented
- Deaths prevented
- Illness avoided or overcome
- Hence, the scope of applying this method is rather vague in the health field.
2. COST-EFFECTIVE ANALYSIS (CEA)
Definition:
Cost-effective analysis is a tool similar to CBA, except that benefits are expressed not in monetary terms but in terms of results achieved.
Key features:
| Feature | Details |
|---|
| Expression of benefits | In health outcomes (non-monetary) |
| Examples of outcomes | Number of lives saved, number of disease-free days |
| Use in health field | More promising than CBA |
| Limitation | Not always possible in many cases |
"This is a more promising tool for application in the health field than cost-benefit analysis."
- K. Park
Examples of measurable outcomes in CEA:
- Number of lives saved per Rs. 1 lakh spent
- Cases detected per rupee invested
- Number of immunizations done per cost unit
3. COST-ACCOUNTING
Definition: Provides basic data on the cost structure of any programme.
Three important purposes in health services:
- Cost control - preventing wasteful expenditure
- Planning and allocation of people and financial resources
- Pricing of cost reimbursement - ensures fair compensation
COMPARISON TABLE: CBA vs CEA
| Parameter | Cost-Benefit Analysis | Cost-Effective Analysis |
|---|
| Benefits expressed as | Monetary terms | Health outcomes |
| Applicability in health | Limited / vague | More practical |
| Comparison possible | Between different sectors | Within health sector |
| Example | Money saved vs. cost | Lives saved vs. cost |
| Limitation | Cannot monetize health | Not always possible |

IMPORTANCE / APPLICATION IN COMMUNITY MEDICINE
- Helps prioritize health programmes when resources are limited
- Assists in rational allocation of healthcare budget
- Enables comparison of alternative intervention strategies
- Useful in National Health Programme planning (e.g., comparing vaccination programmes)
- Guides policy decisions at national and international levels (WHO, government ministries)
SUMMARY BOX
Cost-Benefit Analysis = Compares costs vs. benefits in money β BCR > 1 preferred
Cost-Effective Analysis = Compares costs vs. benefits in health outcomes β More useful in health
Cost-Accounting = Tracks cost structure β Used for cost control, planning, pricing
