AHRQ Stats

Nearly 85 percent of Americans had health care expenses in 2010, which included out-of-pocket payments and payments by Medicaid, Medicare and private insurance. The percentage was generally lower in California, Texas, and New York, and higher in Illinois.

1. AHRQ Releases 2011 Nationwide Emergency Department Sample

AHRQ has released its 2011 Nationwide Emergency Department Sample (NEDS), the largest all-payer emergency department (ED) database in the United States. The NEDS was created to provide data for analyses of ED utilization patterns and to support public health professionals, administrators, policymakers, and clinicians in their understanding of and decisionmaking about this critical source of health care. Constructed with records from AHRQ's State Emergency Department Databases and the State Inpatient Databases, the 2011 NEDS contains data from nearly 29 million ED visits and encompasses all encounter data from more than 922 hospital-based EDs in 30 states. It approximates a 20-percent stratified sample of EDs from community hospitals. Weights are provided to calculate national estimates about the 131 million ED visits that took place in 2011. The NEDS provides information on "treat-and-release" ED visits, as well as ED visits in which the patient was admitted to the same hospital for further care. The NEDS has many research applications as it contains information on hospital and patient characteristics, geographic region, and the nature of the ED visits (e.g., common reasons for ED visits, including injuries). The database includes information on all visits to the ED, regardless of payer—including persons covered by Medicare, Medicaid, private insurance, and the uninsured. The 2011 NEDS is a product of AHRQ's Healthcare Cost and Utilization Project (HCUP) and is available for purchase through the HCUP Central Distributor. Selected aggregate statistics from the NEDS can be accessed at no charge via HCUPnet.

2. CHIPRA Evaluation Highlight Illustrates State Partnerships

The sixth Evaluation Highlight from the national evaluation of the Children's Health Insurance Program Reauthorization Act (CHIPRA) Quality Demonstration Grant Program is available on the AHRQ Web site. Of the 10 grantees that received grant awards, six represent multi-state partnerships involving 14 of the 18 CHIPRA quality demonstration states. This highlight illustrates how states are using the partnerships to improve the quality of children's health care. It describes strategies that states are using to create and maintain cross-state relationships, as well as benefits and challenges of partnering. A supplement to the highlight provides a snapshot of the six multi-state partnerships and the projects they are developing. The analysis covers the first 3 years of these 5-year CHIPRA quality demonstration projects, including a year of planning.

3. Advanced Methods, Delivery System Research Webinar Series Available on AHRQ Web Site

A series of Webinars on advanced approaches to planning, executing, analyzing, and reporting delivery system research is posted on the AHRQ Web site. Evaluating the effectiveness of different approaches to delivering care poses challenges to many of the traditional tenets of designing and conducting research. The series, "Advanced Methods of Delivery System Research," complements those traditional approaches by studying issues including the effects of delivery system change. It was jointly sponsored by AHRQ's Delivery System Initiative and the Agency's Patient-Centered Medical Home (PCMH) program. The package, which includes videos and PowerPoint presentations, is designed to give investigators and researchers a better understanding of social, organizational, technical, and market influences that can help shape future improvement initiatives. The first four Webinars paired authors of papers in the AHRQ PCMH Research Methods Series with an AHRQ grantee or contractor who had conducted research using the selected method. The final Webinar featured guest editors and authors of studies and abstracts from "Integrating Mixed Methods in Health Services and Delivery System Research," an AHRQ-sponsored special issue of Health Services Research published in December.

4. Register Now: February 19 Webinar on Evidence-Based Resources for Advanced-Practice Nurses

AHRQ, in collaboration with the American Association of Nurse Practitioners, is hosting a Webinar on February 19 from 1:00 p.m. to 2:00 p.m. ET on the use of evidence-based recommendations to inform clinical practice. After participating in this Webinar, advanced-practice nurses will be able to:

  • Describe the five major steps in conducting a systematic review.
  • List the evidence-based resources available on the AHRQ Web site, including those available through the Effective Health Care (EHC) Program.
  • Locate the resources available on the U.S. Preventive Services Task Force (USPSTF) Web site, including the Electronic Preventive Services Selector (ePSS) tool.
  • Explain how the EHC Program resources, USPSTF recommendations, and the ePSS tool can be integrated into clinical decisionmaking by advanced-practice nurses.
  • Download the ePSS application to a personal digital assistant or mobile device.

Select to register.

This program was planned in accordance with AANP CE Standards and Policies and AANP Commercial Support Standard and is approved for 1 contact hour of continuing education.

5. All Payer Claims Database Updates Include Increased Data Analysis Capacity

The All Payer Claims Database (APCD) portal in AHRQ's United States Health Information Knowledgebase (USHIK) has been updated and redesigned to improve usability. Updates to the portal, which contains the APCD data dictionaries from participating states, include the following:

  • The most recent reporting specifications for each of the previously loaded states.
  • Colorado APCD reporting specifications.
  • Increased capability to view, analyze, compare, and export state reporting specifications. The home page, list pages, comparisons, and detail pages have all been refreshed.
  • APCD specifications by state, file submissions, or data element lists. Each of these list pages allows a user to filter and/or select a variety of items for comparison.

USHIK is an online, publicly accessible registry and repository of health care–related data, metadata, and standards. USHIK is funded and directed by AHRQ with management support in partnership with the Centers for Medicare & Medicaid Services, and the Centers for Disease Control and Prevention's National Center for Health Statistics.
