Several factors contribute to overtreatment, including:
1. Defensive Medicine: Physicians may prescribe unnecessary tests or treatments to avoid potential lawsuits. 2. Financial Incentives: The fee-for-service model may encourage more procedures and tests. 3. Patient Expectations: Patients often expect or demand aggressive treatments, even when not medically necessary. 4. Technological Advancements: Overreliance on new technologies without sufficient evidence of benefit can lead to overtreatment.
