BackgroundChildren covered by Medicaid are at increased risk of emergency department (ED) utilization.Objective.-To examine whether an association exists between ED use and perceived delay in accessing acute care.Design And SettingCross-sectional study. We used data from the Consumer Assessment of Health Plans Survey collected by Washington State Medicaid in 2000. We used multivariate logistic regression to determine the odds of any ED use, using a model that included whether the parent reported not always receiving illness care for the child as soon as wanted (perceived delay), age, gender, race/ethnicity, health status, presence of a special health care need, primary language, needing an interpreter, parental education, and having a regular provider.SubjectsParents of a random sample of children from 9 Medicaid managed care plans were surveyed if their children were <15 years old and enrolled at least 6 months.Main Outcome MeasuresAny ED use in the past 6 months.ResultsThe response rate was 56.3%, yielding 5142 subjects. Of children with illnesses in the previous 6 months, 69.1% of parents reported that their child always received care as soon as they wanted; 19.9%, 8.2%, and 2.8% reported usually, sometimes, and never, respectively. Not always (vs always) receiving illness care as soon as wanted was significantly associated with increased odds of any ED use (adjusted odds ratio: 1.79; 95% confidence interval: 1.35- 2.36).ConclusionChildren with managed care Medicaid are more likely to use the ED if parents perceive any delay in receiving illness care.
