Decision Tree
You have two options (antibiotic A and antibiotic B) for the treatment of infection. Each antibiotic has two possible outcomes (clinical success of treatment and failure of treatment). Some of patients who receive antibiotics may experience adverse events regardless of the outcomes. Those who experience adverse events will be treated for those events.
Now, you’ll decide which antibiotic you’ll recommend for your patients. All the information you need to make this decision is shown below:
- Assign the relevant cost at each terminal node in the decision tree.
2. Calculate the expected cost at each chance node in the decision tree.
3. Calculate the ICER.
4. Given a willingness-to-pay of $1000 per extra success, which antibiotic would you recommend to your patients? Justify your answer.
