AbstractManaged care plan members provide a population for analysis that minimizes the financial barriers to routine medical care that have been linked to high rates of asthma-related hospitalization, emergency care, and mortality among urban African Americans. We examined patterns of asthma care among 464 African American (AA) and 1,609 Caucasian (C) asthma patients, age 15 to 45 yr, in a southeast Michigan managed care system during 1993. Compared with C, AA had fewer visits to asthma specialists (0.32 versus 0.50 visits/yr, p = 0.002), and filled fewer prescriptions for inhaled steroids (1.44 versus 1.74 Rx/yr, p = 0.038), while being more likely to visit the emergency department with asthma (0.71 versus 0.28 visits/yr, p < 0. 001), to be hospitalized with asthma (0.08 versus 0.03 admissions/yr, p = 0.002), or to have filled prescriptions for oral steroids (0.91 versus 0.59 Rx/yr, p < 0.001). AA were equally likely to have visited a primary care physician for asthma (0.95 versus 0.93 visits/yr, p = 0.81). Similar physician visit profiles and discrepancies in the use of oral steroids persisted when analyzing exclusively low socioeconomic status subgroups. These results suggest that ethnic differences in patterns of asthma-related health care persist within managed care settings and are only partially due to financial barriers.
