The ecology of medical care for children in the United States

Background. Medical care ecology has previously been investigated for adults, but no similar exploration has been made specifically for children. Objective. To describe proportions of children receiving care in 6 types of health care setting on a monthly basis and to identify characteristics associated with receipt of care in these settings. Methods. Nationally representative data from the 1996 Medical Expenditure Panel Survey were used to estimate the number of children per 1000 per month who received care at least once in each type of setting. Multivariate analyses assessed associations between receiving care in various settings and children's sociodemographic factors (age, sex, ethnicity, poverty, parent's education, urban or rural residence, insurance status, and whether or not the child had a usual source of care). Results. Of 1000 children aged 0 to 17 years, on average each month 167 visited a physician's office, 82 a dentist's office, 13 an emergency department, and 8 a hospital-based outpatient clinic. Three were hospitalized and 2 received professional health care in their home. Younger age was associated with increased proportions of children receiving care in all health care settings except dentists' clinics. Poverty, lack of health insurance, black race, and Hispanic ethnicity were associated with decreased receipt of care in physicians' and dentists' offices. Only age ( Conclusions. The ecology of children's medical care is similar to that of adults in the United States in that a substantial proportion of children receive health care each month, mostly in community-based, outpatient settings. In all settings except emergency departments, receipt of care varies significantly by children's age, race, ethnicity, income, health insurance status, and whether they have a usual source of care.
