We read with interest the recent article by O'Connor et al. comparing immunization coverage rates based on different definitions of active patients seen in a pediatric practice of an urban children's hospital.1 O'Connor et al. concluded that the Clinical Assessment Software Application (CASA) designed by the Centers for Disease Control and Prevention (CDC) underestimated immunization coverage rates.
