The importance of personalized Asthma Action Plans for individuals with asthma is emphasized, as well as the importance of finding a plan that works best for each individual's needs. A study assessed the effectiveness of a class led by a pediatric nurse practitioner on resident physician knowledge of asthma self-management and the development of a written action plan. Environmental triggers for asthma are identified, controlled, or removed, and the Asthma Action Plan serves as a medical order. The Missouri Asthma Program provides resources for school nurses and encourages the use of Asthma Action Plans. Monitoring asthma control and providing self-management education are important factors to consider in managing asthma. It is observed that asthma is becoming increasingly prevalent.
