The Asthma Controller Step-down Yardstick

Guidelines for asthma recommend a series of treatment steps (Figure 1) as a framework for disease management.1,2 The steps allow individualized adjustments in controller therapy in an upward or downward manner in response to a patient's level of asthma control over a period of time. For patients with inadequately controlled asthma, a step-up is recommended.1,2 Strategies for stepping up controller therapy are described in detail in the adult and pediatric Asthma Yardsticks.3,4 For patients whose asthma has been well controlled for at least 3 months (or longer for the highest risk patients), controller treatment may be stepped down.
