Question
What is the most cost-effective screening for identifying carcinoma cervix in a population?
The correct answer is
High risk selective screening
Cost-Effective Cervical Cancer Screening Strategy
The most cost-effective method for identifying carcinoma cervix in a population is high risk selective screening.
Rationale for High Risk Selective Screening
- This approach focuses resources on individuals with a higher probability of developing cervical cancer (e.g., based on age, HPV status, sexual history, or previous abnormal results).
- By concentrating screening efforts on this subset, overall costs are reduced compared to screening the entire population (mass screening).
- It maximizes the yield of positive cases relative to the resources invested, making it more efficient.
Evaluating Other Screening Options
- Mass screening involves testing everyone, which can be very expensive and may over-allocate resources to low-risk individuals.
- Multiphasic screening uses multiple tests simultaneously or sequentially, which often increases costs significantly.
- Prospective screening involves observing individuals over time, which is typically used for follow-up or research and isn't the primary method for initial, cost-effective population identification.
Therefore, targeting screening towards high-risk groups offers the best balance between effectiveness and cost for carcinoma cervix detection.
