The Fresno Asthma Project targeted the entire low-income, inner-city, multiethnic population of Fresno, California. For 36 months following a 6-month planning phase, continuing education was provided to a high proportion of physicians, pharmacists, nurses/respiratory therapists, emergency medical technicians, school personnel, and allied health professionals involved in asthma care in Fresno, including virtually all those providing care/services to the target population. Small group patient education was made available and provided in age- and culturally appropriate formats to patients/families in clinics, hospitals, and schools. General and ethnic media and a Speakers Bureau were used to raise public awareness of asthma as a serious but controllable health problem. This community intervention model is particularly appropriate to multiethnic communities. It is relatively low cost (total direct costs were $140,000 per year), uses existing educational resources, and appears to have minimized counterproductive competition. Although morbidity and mortality trend data are not yet available to monitor program impact, penetration into the target community has been substantial: community physicians refer patients to asthma classes, asthma educator training is ongoing through the local American Lung Association chapter, hospitals and managed care systems serving low- income/MediCal patients offer asthma classes, and public schools and HeadStart are institutionalizing asthma awareness and self-management classes.
