Five-hundred life-saving interventions and their cost-effectiveness

Area of Science:

• Health Economics
• Public Health Policy
• Preventive Medicine

Background:

• Assessing the economic value of health interventions is crucial for resource allocation.
• Previous analyses of life-saving interventions often lack standardized cost-effectiveness metrics.
• A comprehensive understanding of cost-effectiveness across diverse interventions is needed.

Purpose of the Study:

• To systematically evaluate and standardize the cost-effectiveness of life-saving interventions in the United States.
• To provide a comparable metric (cost per life-year saved) for a wide range of health and safety strategies.
• To identify variations in cost-effectiveness across different categories of interventions.

Main Methods:

• Systematic review of publicly available economic analyses of life-saving interventions in the U.S.
• Standardization of cost-effectiveness ratios to a common metric: net resource costs per year of life saved.
• Inclusion of 587 distinct behavioral and technological interventions.

Main Results:

• The median cost-effectiveness ratio for all interventions was $42,000 per life-year saved.
• Median costs varied significantly by category: medical interventions ($19,000/life-year), injury reduction ($48,000/life-year), and toxin control ($2,800,000/life-year).
• Intervention costs ranged from cost-saving to over $10 billion per life-year saved.

Conclusions:

• Significant variation exists in the cost-effectiveness of life-saving interventions, highlighting opportunities for optimizing public health spending.
• Medical interventions generally demonstrate higher cost-effectiveness compared to injury and toxin control measures.
• Standardized cost-effectiveness data can inform policy decisions and improve resource allocation for maximizing population health gains.
