A randomized trial comparing peak expiratory flow and symptom self-management plans for patients with asthma attending a primary care clinic.
Great emphasis is placed on educating asthmatics to use action plans to achieve better control of symptoms.
The use of peak flow meters (PFM) has been recommended as an important part of self-management plans.
We studied 92 (47 F) adult patients with asthma in a primary care setting to compare the effectiveness of action plans using either peak flow monitoring or symptoms to guide self-management.
Each patient was instructed in the use of the action plan in the context of a 6-mo asthma education program taught by a nurse.
Patients were already using inhaled corticosteroids or were newly prescribed corticosteroids by their family physician.
Forty-four patients were randomized to the PFM group and 48 to the symptoms group.
Spirometry, symptom scores, quality of life, medication use, and measures of health care utilization and morbidity (emergency department visits, hospitalizations, unscheduled doctor visits, and days lost from work or school) were recorded at baseline and throughout the study period.
PC2O methacholine was measured at the first and at the final visits.
There were significant improvements within groups for FEV1, symptoms score, PC20methacholine, and quality of life, but no between-group differences.
A significant shift from higher to lower daily use of bêta-agonists (p<0.008 for both groups) and significant shifts to higher daily doses of inhaled steroids (p<0.001) occurred in each group. (...)
