Asthma

The asthma module models asthma as a marginal disease process over the demographic population. It owns asthma incidence, prevalence, disability and mortality calculations. Its disease-free state is a derived residual inside the asthma partition, not another population.

Clinical treatment calculations are supplied by separate intervention modules. CR1 changes oral-prednisolone treatment for severe exacerbations. CR3 combines the declared inhaled and maintenance-treatment components. Tobacco effects arrive through the declared tobacco-to-asthma incidence relationship.

The compiler reconciles the opening asthma states to the demographic population, inserts the selected intervention or risk-factor components, and supplies annual mortality. Baseline and comparison contain the same asthma graph and differ only in parameter values.

The source repository is ncd-asthma (opens in a new tab). The current module contract describes its inputs, outputs, opening-state method, annual state surface and metric inputs.
