Data Sources
All mental health models in the WHO platform use data from validated international sources. Data is fetched via the unified-api and can be reviewed and edited in the platform's Assumptions page before running analyses.
Data Architecture
The platform uses three types of data sources:
1. Demographic Data (FHDB)
Source: Forecast Health Database (FHDB)
Content:
- Population counts by age and sex
- Fertility rates
- All-cause mortality rates
- Life expectancy
Provenance: UN Population Division, WHO life tables
Access: Fetched via unified-api data_fetcher_label: "fhdb"
2. Epidemiological Data (Mental Health)
Source: Mental health disease observations database
Content:
- Prevalence by age, sex, and health state
- Incidence rates
- Remission rates
- Relapse rates
- Disease-specific mortality
Provenance: Global Burden of Disease (GBD) study, published epidemiological studies, clinical trial databases
Access: Fetched via unified-api data_fetcher_label: "mental-health"
3. Cost Data
Source: Multiple sources depending on parameter type
Medicines and Diagnostics: Embedded in scenario JSON files, sourced from WHO-CHOICE, MSH International Medical Products Price Guide, and country-specific procurement data
Workforce Salaries: Static JSON file in platform (public/workforce_salary_by_country.json), sourced from ILO labor statistics and WHO health workforce databases
Facility Visit Costs: Static JSON file in platform (public/visits_by_country.json), sourced from WHO-CHOICE and published costing studies
Access: Static files loaded at app initialization; can optionally be fetched via unified-api data_fetcher_label: "costs"
Epidemiological Data
| Parameter | Source | Description |
|---|---|---|
| Prevalence | Global Burden of Disease (GBD) study | Age and sex-specific prevalence |
| Incidence | Published epidemiological studies | Rates of new cases |
| Remission | Clinical studies | Rates at which individuals recover |
| Relapse | Longitudinal studies | Rates at which individuals in remission experience recurrence |
| Mortality | Meta-analyses of mortality studies | Excess mortality associated with the condition |
Disability Weights
Disability weights are sourced from the Global Burden of Disease study, reflecting the severity of health loss associated with different disease states.
Intervention Efficacy
Data on the effectiveness of various interventions (e.g., psychotherapy, pharmacotherapy) comes from randomized controlled trials and meta-analyses in the scientific literature.
Reviewing Data in the Platform
When you run an analysis, the platform displays all input data on the Assumptions page organized by category:
- Demography: Population structure, births, deaths
- Epidemiology: Disease rates by age and sex
- Intervention Parameters: Coverage, effect sizes
- Cost Parameters: Unit costs for all resources
You can click on any value to edit it before running the analysis. Edits apply to both baseline and comparison scenarios unless different parameters are specified in scenario definitions.
