Further study details as provided by National Heart, Lung, and Blood Institute (NHLBI):

Study Start Date: August 1994
Estimated Study Completion Date: July 1999
Detailed Description:


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.


Primary outcome Frequency and cost of health care utilization for asthma, and asthma-specific quality of life

Key secondary outcomes Prebronchodilator FEV1; diurnal variability in PEF
