The West Philadelphia asthma care implementation study (NHLBI# .

Asthma is the most common chronic condition among children, with low-income families living in urban areas experiencing significantly higher rates. Evidence based interventions for asthma are routinely implemented in either the home, school, or primary care setting. However, even when caregivers of poor children are engaged in asthma interventions in one setting, they often have to navigate challenges in another setting, such as an under-resourced home, non-supportive school, or disengaged health care provider.
