Objectives • Define the importance of allergy evaluation in asthma management. • Discuss the 3 high risk groups appropriate for immediate allergy evaluation. • Define the 2 methods for assessing specific allergen sensitizations. • Discuss the need to include the ACT or the Asthma APGAR as part of asthma and allergy evaluation visits.

Most Asthma not Controlled • Adults with moderate or severe persistent asthma • Prior to study patients were considered 55% controlled by their clinicians • Study results: 55% of patients were uncontrolled found to be uncontrolled • Incomplete adherence • Inadequate inhaler technique • Unaddressed triggers Peters SP, et al.

Barriers and facilitators for practice change and staff comments Barriers Staff comments regarding barriers Time “It takes time to try something new—we don’t have time” Limited physician buy in “Some physicians are just not willing to try anything new.” Limited staff acceptance “Some of the nursing staff only do what is required by their physicians.” Lack of centralized mandate “Our patients are doing OK” Unsure of need Facilitators Staff comments regarding facilitators Feedback from patients “[With the Asthma APGAR] we actually knew what the patient was Asthma as quality site target doing and thinking”. Case reports “I got more information than I have ever had and…. it improved care.” Ease of use of tools “Using the system definitely improved the asthma care and the Tools from primary care patients liked it.” Yawn BP, et al.
