News and Announcements

HCUP Fast Stats Data Update!

AHRQ has released new information in HCUP Fast Stats—Trends in Inpatient Stays. This section of the larger National Hospital Utilization and Costs topic examines national trends in inpatient utilization, costs, and mortality across a variety of patient characteristics. The update adds national statistics for 2016 to this section of Fast Stats. 
For additional information, please refer to the Fast Stats Frequently Asked Questions page or contact HCUP User Support.

2016 National Inpatient Sample (NIS) Data Now Available on HCUPnet

Nationwide statistics from the 2016 NIS now have been added to HCUPnet, the free, online query system based on HCUP data.
HCUPnet provides health care statistics and information for hospital inpatient, emergency department, and ambulatory settings, as well as population-based health care data on counties.
This is just one of many updates the tool has received over the last few months. Other additions include graphs of two-way statistics, inclusion and refinement of ICD-10-CM/ICD-10-PCS queries, and aggregation of community-level statistical tables by 3-year increments.
To check out the updates and start your own query, visit HCUPnet today at https://hcupnet.ahrq.gov/.

HCUP Q&A

Question: I am interested in conducting a trend analysis of pediatric discharges now that the 2016 Kids’ Inpatient Database (KID) is available. Before I get started, I have a few questions:
  • Because the KID is not created annually, I am wondering whether it is possible to substitute another HCUP database for the years that the KID is not available. If so, which HCUP database should I use?
  • I am interested in conducting an analysis on a specific subpopulation in the KID, but I am not sure how to approach a trend analysis for a subpopulation of interest. Is there any issue with subsetting each individual data year of the KID prior to combining the multiple years to examine trends?
  • Are there issues I should consider when working with the KID longitudinally?
Answers:
Because the KID is not created annually, I am wondering whether it possible to substitute another HCUP database for the years that the KID is not available. If so, which HCUP database should I use?
You are correct. The KID includes data for a single calendar year, or January to December of the release year. If you are interested in pediatric discharges for the interim years, we recommend using the NIS, which includes both pediatric and adult records. Researchers often use the KID for available years and fill in the intervening years with data from the NIS for trend analyses.
I am interested in conducting an analysis on a specific subpopulation in the KID, but I am not sure how to approach a trend analysis for a subpopulation of interest. Is there any issue with subsetting each individual data year of the KID prior to combining the multiple years to examine trends?
We do not see an issue with subsetting each year of the KID prior to combining multiple years as long as each subset includes at least one (possibly dummy) record for each hospital. This is done to ensure correct standard errors. For additional information on conducting subpopulation analyses with the KID, refer to HCUP Method Series Report #2005-07, Calculating Kids' Inpatient Database (KID) Variances.
Are there any other issues that I should consider when working with the KID longitudinally?
Yes, the following issues are worth considering when working with the KID longitudinally to analyze trends:
  • The data element YEAR should be added as a stratification variable; otherwise the statistical routines will treat the data as though they were sampled from a single year. Additional information on this approach is available in Method Series Report #2015-09, Calculating National Inpatient Sample (NIS) Variances for Data Years 2012 and Later.
  • Beginning with the 2012 KID, the hospital identification data element changed from HOSPID to HOSP_KID, and HOSP_KID is not linkable across years. We recommend clustering by HOSP_KID and YEAR beginning with 2012 data.  
The 2016 KID uses ICD-10-CM/PCS diagnosis and procedure codes. Prior years used ICD-9-CM diagnosis and procedure codes only. Additional information is available on the KID Database Documentation page..
