New Community-Level Statistics on HCUPnet on Stays for Alcohol and Other Drugs
Hospital stays involving alcohol, opioids, stimulants and other drugs are now available as new county- and region-level statistics on HCUPnet. This new resource includes 32 participating States for years 2013 and 2014 by total number of discharges and as a rate per 100,000 population. Statistics can be distinguished by several variables, including age group, sex, payer and type of stay, and by hospital costs/charges and lengths of stay.
To start your search, navigate to the HCUPnet starting page, click on “Create a New Analysis.” You should then go through the following steps:
- Choose Community.
- Choose a Year.
- Choose your State.
- Choose Counties.
- Choose Diagnosis/Procedure.
- Choose Stays for Alcohol and Other Drugs.
- Agree to the terms of the data use agreement.
An example query for Cook County, IL below shows an opioid-related hospitalization rate of 440 per 100,000 people in 2014. By contrast, Starr County, TX, had a rate for opioid-related hospitalizations of 18 per 100,000 people (not shown).

Newly Released: HCUP Tools Loading Tutorial
HCUP Tools, when applied to HCUP databases or other administrative data sets, systematically create new data elements from existing data and enhance a researcher’s ability to conduct analyses.
Following the transition to the International Classification of Diseases, Tenth Revision, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) on October 1, 2015, the HCUP Tools are no longer preloaded onto HCUP databases. To assist researchers, AHRQ has released the HCUP Tools Loading Tutorial, which provides a step-by-step guide to locating, downloading, and applying HCUP Tools to HCUP’s administrative databases. The tutorial also shows users how to verify that the most up-to-date version of HCUP Tools is being used.
Additional information also is provided within a separate announcement in the HCUP Q&A section of this newsletter.
Now Available: The 2015 Nationwide Emergency Department Sample (NEDS)
The 2015 Nationwide Emergency Department Sample (NEDS) is now available. The NEDS is the largest all-payer emergency department database in the United States and contains information about geographic, hospital, patient, and visit characteristics. Unweighted, it contains data from approximately 31 million emergency department (ED) visits each year. Weighted, it estimates roughly 143 million ED visits.
Because of the transition to ICD-10-CM/PCS on October 1, 2015, the file structure and the location of many of the data elements within the files that constitute the 2015 NEDS have changed. Users are encouraged to review the ICD-10-CM/PCS Resources Page prior to analyzing outcomes affected by this change in the ICD coding scheme.
The NEDS enables analyses of ED utilization patterns and yields information that supports public health professionals, administrators, policymakers, and clinicians as they make decisions regarding this critical source of care.
The 2015 NEDS is available for purchase through the HCUP Central Distributor.

Question: I recently purchased the 2015 National Inpatient Sample (NIS) and noticed that HCUP Tools, such as the Clinical Classifications Software (CCS) and comorbidity variables, are not on the 2015 Quarter 4 (Q4) files. I would like to add the HCUP Tools to my 2015 Q4 files, but before I do, I have a few questions about the process.
- Why were the tools removed from the 2015 Q4 files?
- Are HCUP Tools for ICD-10-CM/PCS available?
- What version of the ICD-10-CM/PCS tools should I be using?
- Are there load programs or additional documentation to help me apply the ICD-10-CM/PCS HCUP Tools to the 2015 Nationwide databases?
- Is there any guidance available for users performing longitudinal trend analyses including the ICD-10-CM/PCS data?
Why were the tools removed from the 2015 Q4 files?
Data elements derived from AHRQ Software Tools (i.e., CCS, Chronic Condition Indicator, and Procedure Classes) are not available in the Q4 files because the ICD-10-CM/PCS versions of these tools are still under development. In the 2015 NIS, data elements based on AHRQ Software Tools are unavailable for the Diagnosis and Procedure Groups File for Q4 as well as the Disease Severity Measures File for Q4.
Are HCUP Tools for ICD-10-CM/PCS available?
HCUP Tools have been translated to ICD-10-CM/PCS as part of the conversion to the new coding system on October 1, 2015. Beta versions of the ICD-10 HCUP Tools are available at https://www.hcup-us.ahrq.gov/
tools_software.jsp. This translation is not final and is being modified on an ongoing basis.
What version of the ICD-10-CM/PCS tools should I be using?
The latest version of HCUP Tools should always be used. Updated versions of the HCUP Tools are released in the fall (usually mid-to-late October) to reflect the annual release of new or updated Federal fiscal year codes, although occasionally the HCUP Tools are rereleased during a Federal fiscal year to apply changes to the Tools assignment of specific codes. HCUP Tools now incorporate a versioning system that refers to both the Federal fiscal year and an incremented release number (e.g., CCS for ICD-10-CM/PCS Version 2018.1).
The latest version is always available on the HCUP-US Web site. As an example, the latest version of the CCS for ICD-10 is available in the Downloading Information of CCS for ICD-10-CM/PCS Tool section of the Beta CCS for ICD-10-CM/PCS page of the HCUP-US Web site.
Are there load programs or additional documentation to help me apply the ICD-10-CM/PCS HCUP Tools to the 2015 Nationwide databases?
For users wishing to append the ICD-10-CM/PCS HCUP Tools to the 2015 Nationwide databases, ASCII versions of the ICD-10 HCUP Tools are available for use with user analytic software such as SAS®, Stata®, and IBM® SPSS Statistics. The ZIP file that includes the ASCII version of the ICD-10 HCUP Tool also includes a Load Program that is unique to that HCUP Tool and a 1–2-page Load Guide that includes step-by-step instructions. The HCUP Tools Loading Tutorial also walks users through the process of locating, downloading, and applying HCUP Tools, using the CCS for ICD-10-PCS as an example.
Is there any guidance available for users performing longitudinal trend analyses including ICD-10-CM/PCS data?
Users are encouraged to review the ICD-10-CM/PCS Resources Page on HCUP-US for guidance on analyzing outcomes that may be affected by the transition to the ICD-10-CM/PCS coding system. Several reports are available that offer HCUP recommendations for reporting trends spanning the ICD-9-CM and ICD-10-CM/PCS coding systems. Also provided are other Federal or State Web-related resources with information on ICD-10-CM/PCS.
The HCUP e-News is available online at the HCUP-US Web site and distributed via the HCUP Mailing List.
