Background: Demographic and socioeconomic factors have an impact upon
the morbidity and mortality rates of asthma in inner-city pediatric po
pulations. Many pediatric patients with asthma use the emergency room
as their primary care physician, while a smaller number of children wi
th asthma use the allergy-immunology clinic. Objective: We examined th
e demographic and socioeconomic characteristics of asthmatic patients
using the emergency room as their primary care physician and of those
attending the allergy-immunology clinic in the same inner-city hospita
l. We compared the morbidity and cost of care of asthmatic patients wh
o received their medical care in the emergency room to that of those w
ho received their care in the allergy-immunology clinic. Methods: Fift
y consecutive emergency room patients and 25 clinic patients were stud
ied using an identical questionnaire. Results: There was no difference
between the two groups in the total number of individuals per househo
ld, children per family, monthly income, type or size of dwelling, fin
ancial problems purchasing medications, health insurance type, distanc
e to the medical center, or education of the caretaker. Severity of as
thma was not different in the two groups before the start of the study
. The only significant demographic difference was in age: 10.6 years f
or the clinic group and 7.8 years for the emergency room group (P < .0
02). Clinically, in the year preceding the interview, the clinic group
had significantly less nocturnal cough (P < .025), sleep interruption
(P < .001), weekly asthma (P < .05), and emergency room visits (P < .
09). The allergy clinic group had an approximate average savings of $1
37 per patient per year. Hospital admissions and emergency room costs
were increased by a small group of three allergy clinic patients, decr
easing the difference in the cost of care between the two groups. Conc
lusion: The data showed that patients who attended the emergency room
and those who attended the allergy-immunology clinic were not demograp
hically or socioeconomically different. The decreased morbidity of ast
hma and cost of care for the allergy clinic patients, as opposed to th
e emergency room patients, are likely due to the care given in the all
ergy-immunology clinic.
