Objective: To determine the sensitivity, specificity, and predictive value
of a simple, self-administered questionnaire for the diagnosis of asthma in
children.
Study design: A questionnaire specifically designed to assist primary care
providers in making a diagnosis of asthma in children was developed and adm
inistered in 4 different primary care and subspecialty clinics, validated,
and then used as part of an asthma management program called Easy Breathing
. Asthma diagnoses were made according to recommended National Asthma Exper
t Panel Guidelines.
Results: Four questions on the survey were shown to be sensitive and specif
ic for asthma. The sensitivity was greater for all levels (mild, moderate,
and severe) of persistent asthma than for mild, intermittent asthma. A posi
tive response to any 1 of the 4 questions was over 94% sensitive for asthma
; a negative response to all 4 questions was 55% specific for ruling out as
thma.
Conclusions: Patient responses to 4 specific respiratory symptom questions
can assist primary care providers in diagnosing asthma in children. Primary
care providers serving pediatric populations at high risk for asthma shoul
d consider asking patients or their parents these 4 questions regarding ast
hma symptoms on a regular basis.
