WHO Mental Health Platform
Cost-effectiveness modelling for mental health interventions
About This Platform
The WHO Mental Health Platform is a cost-effectiveness modelling tool for evaluating mental health interventions. It allows health economists and policymakers to compare baseline and intervention scenarios, inspect key assumptions, and estimate health impacts, resource needs, costs, and cost-effectiveness in a country context.
This tool models intervention coverage, effectiveness, and costs based on epidemiological data and published evidence. It generates estimates of health outcomes (DALYs averted), resource needs (workforce, medications, visits), and cost-effectiveness ratios to inform priority-setting and planning.
It is not designed to replace WHO guidance, generate definitive policy recommendations, or stand in for local validation of assumptions, costs, and service-delivery patterns.
This is a modelling tool, not definitive policy guidance. Results depend on model assumptions and input parameters. Users should interpret outputs in context and consult official WHO guidelines and local expertise when making decisions.
How to Use This Tool
On each workflow page, use the navigation button in the top right to move forward, and use the Help button there if you need a plain-language explanation of what the page is for.
- Configuration: choose the condition, country, start year, and final year.
- Baseline: describe current care and current coverage.
- Intervention: describe what changes under the proposed approach.
- Assumptions: review or edit the background epidemiology and model inputs if needed.
- Clinical Pathways: inspect how the model turns people reached into visits, staff time, medicines, and costs.
- Service Inputs: adjust how care is delivered, such as visits, duration, and shares receiving each step.
- Unit Costs: review and update prices, staff rates, medicine costs, and inpatient costs.
- Results: run and compare the health, cost, resource, and cost-effectiveness outputs.
The WHO Mental Health Platform is developed in collaboration with the World Health Organization. This tool was created by Forecast Health.
Disclaimer: This is a decision-support tool for cost-effectiveness analysis. Model outputs are estimates based on available data and assumptions. They should not be interpreted as definitive recommendations or medical advice. Users should validate inputs for their context, interpret results critically, and consult official WHO guidelines and local expertise when formulating policy or clinical decisions.
