Association between asthma control and healthcare costs: Results from a German linked data study

This study aimed to evaluate differences in healthcare resource utilization and cost among patients with controlled and uncontrolled asthma. Claims data from a German sickness fund was linked to patient survey data. Outpatient physicians enrolled patients and assessed asthma control using the ACT questionnaire. All-cause and asthma-specific healthcare resource use (HCRU)/costs were compared descriptively and based on multivariable models using a continuous ACT score.
