Deloitte Health-Economic Impact Calculator

This calculator helps healthcare professionals and policymakers evaluate the health-economic impact of interventions using Deloitte's methodology. It estimates the return on investment (ROI), cost-effectiveness, and other key metrics to inform decision-making.

How to Use This Calculator

To calculate the health-economic impact of a healthcare intervention:

Enter the total cost of the intervention in your local currency.
Input the number of people who will benefit from the intervention.
Specify the quality-adjusted life years (QALYs) gained per beneficiary.
Enter the discount rate (typically 3-5% for healthcare interventions).
Click "Calculate" to see the results.

The calculator will display the incremental cost-effectiveness ratio (ICER), net present value (NPV), and other key metrics.

Formula Used

The calculator uses the following formulas to estimate health-economic impact:

Incremental Cost-Effectiveness Ratio (ICER) = Total Cost / Total QALYs Gained

Net Present Value (NPV) = Σ [ (Benefits - Costs) / (1 + Discount Rate)^t ] for each time period t

Where:

Total Cost = Cost of the intervention
Total QALYs Gained = Number of beneficiaries × QALYs per beneficiary
Discount Rate = Annual discount rate (typically 3-5%)

Note: The discount rate accounts for the time value of money and is typically set between 3% and 5% for healthcare interventions.

Worked Example

Let's calculate the health-economic impact of a new diabetes treatment:

Example Scenario:

Cost of intervention: $100,000
Number of beneficiaries: 1,000
QALYs per beneficiary: 0.5
Discount rate: 3%

Using the formulas:

Total QALYs Gained = 1,000 × 0.5 = 500 QALYs ICER = $100,000 / 500 = $200 per QALY NPV = Σ [ ($100,000 - $100,000) / (1.03)^t ] = $0 (assuming no ongoing costs)

This means the intervention costs $200 per QALY gained and has a net present value of $0 in this simplified example.

Interpreting Results

The results from this calculator can be interpreted as follows:

Incremental Cost-Effectiveness Ratio (ICER)

A lower ICER indicates a more cost-effective intervention. Typically, interventions with an ICER below $50,000 per QALY are considered cost-effective.

Net Present Value (NPV)

A positive NPV indicates that the intervention is financially beneficial. A negative NPV suggests that the intervention may not be cost-effective.

Practical Implications: Use these metrics to compare different interventions and make informed decisions about resource allocation.

Frequently Asked Questions

What is the difference between ICER and NPV?: The Incremental Cost-Effectiveness Ratio (ICER) measures the cost per QALY gained, while the Net Present Value (NPV) accounts for the time value of money and ongoing costs.
How do I choose the discount rate?: The discount rate typically ranges from 3% to 5% for healthcare interventions, reflecting the opportunity cost of capital.
Can I use this calculator for any type of healthcare intervention?: Yes, this calculator can be used for a wide range of healthcare interventions, including new treatments, preventive measures, and public health programs.
What are the limitations of this calculator?: This calculator provides estimates based on the inputs provided. Actual outcomes may vary due to factors not accounted for in the model.
