Analysis of 2006 Maine Emergency Department Use


This study, conducted on behalf of the Emergency Department Use Work Group of the Maine Advisory Council on Health System Development provides an analysis of visits to hospital emergency departments in Maine that took place in 2006. The study relied on two sources of data: a comprehensive file of hospital discharge records provided by the Maine Health Data Organization; and comprehensive claims records for most privately insured residents in Maine and most MaineCare members. The 2006 data used for this analysis pre-dated some of the initiatives undertaken by the Department of Human Services to improve access to primary care and reduce emergency department use among MaineCare members.<p></p>
Key findings with regard to emergency department (ED) use:<li>
Maine's emergency department use in 2006 was, in aggregate, about 30% higher than the national average.
<li>Maine's rate of use in every age cohort was higher than the national average for the same age cohort.
<li>The highest prevalence of frequent ED users (4 or more visits in a year) is found among infants, and 19 to 24 year olds.
<li>Use of emergency department care for outpatient care by MaineCare members is more than three times as high (918 outpatient visits per 1000) as rates of use by privately insured residents (284 per 1000).
<li>The uninsured are responsible for 9 percent of emergency department visits. ED visits by uninsured patients are concentrated among young adults. Between the ages of 15 and 44, 15 percent of emergency department visits are generated by the uninsured.
<li>Rate of emergency department use varies substantially by health service area; Geographic variation in emergency department use rates is seen among both privately insured and MaineCare members with substantial overlap of high and low use areas for these two populations, suggesting that use rates are affected by area-specific health system factors that affect the total population.
<li>A review of diagnoses frequently seen in emergency departments in Maine suggests that a substantial number of visits are made for conditions that could be appropriately treated in office or clinic settings.</li>

Dr. Ziller to speak on Rural Implementation and Impact of Medicaid Expansions

The impact of the ACA Medicaid expansion on health care coverage and access in rural areas is largely unknown and will depend on the different state policy contexts in which the expansions are implemented and on existing system capacity. Understanding how many rural residents are likely to become newly eligible for Medicaid under the ACA, as well as their characteristics and health status, will provide important information to aid policymakers in structuring outreach and enrollment strategies and ensuring that the healthcare infrastructure and delivery systems in rural areas can address the needs of these individuals.

On March 18th, Dr. Ziller, Deputy Director of the Maine Rural Health Research Center at the University of Southern Maine, will present via a SHARE webinar, nationally representative information identifying rural-urban differences among low-income non-elderly adults (18 to 65) in the following areas:

  • Medicaid eligibility, pre-ACA
  • Medicaid participation, pre-ACA
  • New Medicaid eligibility in 2014

Dr. Ziller will also analyze the characteristics associated with any rural-urban differences in the above areas. Characteristics to be considered include age, gender, employment, education, income, Census region, health status, current relationship to primary care provider, primary care supply, and FQHC availability.

This webinar is based on Dr. Ziller's research under a State Health Access Reform Evaluation (SHARE) grant to inform federal and state implementation of the ACA Medicaid expansion by estimating the size and characteristics of the rural population likely to be newly eligible.
