• Health Economic Modeling: I can build and interpret health economic models (e.g., Markov models, decision trees) to estimate the long-term costs and benefits of different interventions. These models are particularly useful for evaluating the cost-effectiveness of new technologies or treatments.
• Decision-Making Frameworks: I’m adept at using health economic principles to inform healthcare decision-making. This includes understanding the importance of considering both clinical effectiveness and economic efficiency when making choices about resource allocation and treatment strategies.

For example, in a recent project, I conducted a cost-effectiveness analysis comparing two different treatments for a chronic condition. This involved developing a Markov model to project long-term costs and outcomes, resulting in evidence-based recommendations for the most cost-effective approach.
