Background:
Disadvantaged urban children with asthma are at high risk for undermanagement of their disease and poor compliance with inhaled corticosteroids (ICS).
Objective:
To determine whether spatial accessibility (SA) of retail pharmacy services is associated with ICS compliance.
Methods:
Caregivers of 137 urban high-morbidity asthmatic children attended a comprehensive intervention to improve asthma care and outcomes. Subsequent ICS compliance was determined at 1, 3, and 6 months. We modeled 18 measures of SA to 339 pharmacies using logistic regression and adjusting for numerous covariates.
Results:
No relationships between SA and compliance were found.
Conclusions:
In this group of disadvantaged urban children with severe asthma, compliance with ICS was not significantly associated with SA of retail pharmacy services.

The capillary endothelial barrier allows only smaller molecules below 600 Da (Daltons) to pass through. It also restricts drugs like heparin that are bound to blood components, limiting their movement within the bloodstream.
