About

Evaluate the incremental effectiveness of peak flow monitoring ove symptom monitoring as a management tool to enhance asthma control in adults >= 50 years with moderate-severe asthma.

Full description

BACKGROUND:

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.

DESIGN NARRATIVE:

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

The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.

Sex: All

Ages: 50 to 90 years old

Volunteers: No Healthy Volunteers
