What role does data play in shaping healthcare policies?

Data is pivotal in shaping healthcare policies in several ways:

1. Evidence-Based Decision Making: Reliable data allows policymakers to make informed decisions that are based on empirical evidence rather than assumptions.
2. Tracking Disease Trends: Surveillance data helps in understanding disease trends and patterns, which is essential for planning and implementing control measures.
3. Evaluating Policy Impact: Data helps in evaluating the effectiveness of implemented policies and making necessary adjustments.
4. Resource Allocation: Data-driven insights help in the efficient allocation of resources to areas where they are most needed.
