Objective: To describe the utilization of emergency departments (ED) using a national database with asthma as a primary or secondary diagnosis for pediatric and young adult populations with Medicaid/Children's Health Insurance Program (CHIP). Study Design: 2010 National Hospital Ambulatory Medical Care Survey (NHAMCS) ED data was used to create a dependent variable for asthma (diagnosis code 493) in patients under 25 years old with Medicaid/CHIP. Descriptive statistics using frequency and cross-tab analysis examined utilization and geographic region while controlling for race/ethnicity. Chi-square was used to test for any statistically significant relationships among variables. Population Studied: ED patients under 25 years old with a primary or secondary asthma diagnosis on Medicaid/CHIP Principal Findings: A combined variable of asthma as a primary or secondary diagnosis in patients less than 25 years old with Medicaid/CHIP insurance resulted in 2,225 Patient Record Forms (PRFs) (6.5% of overall NHAMCS ED sample size). Male cases outnumbered female cases by 2:1 ratio. Out of 2,225 PRFs, 985 were non-Hispanic White (44.3%), 751 were non-Hispanic Black (33.8%), 407 were Hispanic (18.3%) and 82 were other (3.7%). 658 PRFs were from the Northeast region (29.6%), 502 from Midwest (22.6%), 684 from South (30.7%), 381 from West (17.1%). Non-Hispanics Whites made up the highest concentration in Midwest (52%), highest concentration of Non-Hispanic Blacks were in the South (44.7%), highest concentration of Hispanics came from West (33.9%). When controlling for race/ethnicity, there was a statistically significant relationship between ED utilization for Medicaid/CHIP patients less than 25 years of age with an asthma diagnosis and geographic region for non-Hispanic Blacks (p < .001) and Hispanics (p < .001). 53% of the studied patient population was categorized on a severity scale as immediate, emergent or urgent at nurse triage. Conclusion: There was a statistically significant relationship in the utilization of EDs for patients under 25 years old with asthma as a primary or secondary diagnosis and Medicaid/CHIP insurance who are Non-Hispanic Blacks and Hispanics. Overall, non-Hispanic Whites made up the majority of cases, reminding us that NHAMCS is a national survey and may not be representative of major urban hospitals that traditionally serve a greater minority population with uncontrolled asthma. About half of the studied population may utilize the ED for routine asthma care. Policy Implication: Medicaid/CHIP patients often face barriers to timely access for quality primary care and/or lack adequate resources for optimal self-management of asthma.
