Influence of caregiver and provider communication on symptom days and medication use for inner-city children with asthma.
BACKGROUND
Effective pediatric guideline-based asthma care requires the caregiver to accurately relay the child's symptom frequency, pattern of rescue and controller medication use, and level of asthma control to the child's primary care clinician.


OBJECTIVE
This study evaluated the longitudinal effects of a caregiver-clinician asthma communication education intervention (ACE) relative to an asthma education control group (CON) on symptom days and controller medication use in inner-city children with asthma.


METHODS
231 inner-city children with asthma, recruited from urban pediatric emergency departments (EDs) and community practices, were followed for 12 months. Data included number of symptom days and nights, ED visits, hospitalizations, presence of limited activity, and controller medication use over 12 months. Pharmacy records were used to calculate controller to total asthma medication ratios as a proxy of appropriate controller medication use. Multivariate logistic regression models were used to identify factors associated with number of symptom days and nights over the past 30 days at the 12-month follow-up.


RESULTS
Most caregivers rated the communication with their child's clinician as high. Unadjusted and adjusted rates of symptom days and nights did not differ by group at follow-up. ACE children tended towards a higher controller to total medication ratio at 12 months as compared to CON children (mean ratio: ACE: 0.54, SD 0.3; CON, 0.45, SD 0.4; p = .07). Activity limitation due to asthma and persistent asthma severity were the only factors significantly associated with reporting any symptom day within the past 30 days, adjusting for treatment group, number of oral corticosteroid courses and number of clinician visits in the last 6 months, seasonality, insurance type, and controller to total asthma medication ratio covariates.


CONCLUSIONS
A home-based caregiver asthma communication educational intervention was not associated with decreased symptom days. However, a trend was noted in higher controller to total medication ratios in the intervention group. Inner-city caregivers of children with asthma may require a health systems approach to help convey the child's asthma health information to their clinician.
