Overuse of rescue medication among asthma patients is associated with increased exacerbations and higher total and asthma-related healthcare costs.

Overuse of rescue medication among asthma patients is associated with increased exacerbations and higher total and asthma-related healthcare costs.

Subacute lack of asthma control (SALAC) predicts subsequent asthma exacerbation and may improve health plan members’ asthma control and healthcare utilization associated with asthma exacerbation.
