Asthma medication ratio (AMR) greater than or equal to 0.5 (ages 5-45 years)
Individuals with an asthma medication ratio (AMR) greater than or equal to 0.5 (numerator), among Individuals with persistent asthma aged 5-45 (denominator)
Asthma is one of the most common chronic respiratory diseases. Despite an observed decline in asthma complications in developed countries over the past decade, the condition is associated with an unacceptable burden for patients, families and health care systems. Moreover most asthma associated mortality is preventable with proper management. Regular daily controller therapy is considered the mainstay of persistent asthma management and reduces the risk of complications, including exacerbation, hospitalization, and mortality . Overuse of reliever medications (primarily inhaled short acting beta agonists) indicates inadequate control and is associated with adverse outcome .
