The intervention combined case management elements from NCICAS (Evans et al.
The teams underwent rigorous training and had lighter caseloads compared with NCICAS counterparts.
According to analysis on the frequency of severe asthmatic episodes that result in hospitalization or death, NCICAS results indicate that asthma is more prevalent among low-income and minority families.
RESULTS: Asthma symptoms during the previous 2 weeks decreased from 6.5 days at enrollment to 3.6 days at the 12-month symptom assessment (a 45% reduction, p < 0.001), consistent with changes observed after NCICAS and ICAS interventions (35% and 62% reductions in symptom days, respectively).
Post-intervention changes in symptoms were consistent with previous randomized trials of NCICAS and ICAS interventions.
For example, in the NCICAS study, Weil and colleagues (1999) found that caregiver mental health was the only significant psychosocial predictor of number of hospitalizations for asthma, suggesting that interventions for low-income, urban families should assess and target family processes associated with parental depression (e.g., emotional neglect of children, inconsistent discipline).
Both interventions were cost effective based-upon symptom-free days (SFD) The NCICAS intervention cost was $9.20 per SFD [95% confidence interval (CI), $12.56-$55.29].

The NCICAS study was the first report that examined mouse allergen in residential environments (Phipatanakul et al.
In contrast to the NCICAS study, we did not observe an association between cockroach allergen and mouse allergen in the bedroom, although their level of correlation was moderate (r = 0.18) (Phipatanakul et al.
The NCICAS documented the association between cockroach allergen exposure and symptoms in sensitized children (6), and data from the NCICAS and elsewhere (6,9,14,15) suggest that most inner-city children with asthma are sensitized and exposed to multiple indoor allergens (16) and highly exposed, to environmental tobacco smoke (ETS).
Our study was more heterogeneous than either the NCICAS or HAS studies with a greater range in attained education, ethnic diversity, housing type, and population density.
