We propose a five-year Demonstration and Education project to assess the incremental value of peak flow monitoring (PFM) over symptom monitoring (SM) as a management tool for asthma control in adults greater than or equal to 50 years with moderate-severe asthma. We will develop three parallel asthma education programs for older adults using as our base an existing asthma education program (AIR/Kaiser Adult Education Program) of demonstrated efficacy for adults ,50 years of age.
