2017 National Inpatient Sample (NIS) Data on HCUPnet

Data from the 2017 National Inpatient Sample (NIS) have now been added to HCUPnet, the free, online query system that provides statistics and data tables based on HCUP data. The large sample size of the NIS is ideal for developing national and regional estimates and enables analyses of rare conditions, uncommon treatments, and special populations.
HCUPnet’s easy, step-by-step process allows users to explore many healthcare topics relating to hospital inpatient services and ED settings. Users can also generate tables and graphs on national, regional, and county-level statistics including hospital readmissions and trends on hospital and ED use in the United States.
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 readmission analysis using the HCUP Nationwide Readmissions Database (NRD). Before I get started, I am hoping to learn a bit more about how the NRD can be used as well as some aspects of the methodology for the NRD’s design.
  • Can I combine years of the NRD to analyze readmissions across years?
  • Does the NRD include data elements that identify readmissions?
  • How are transfers handled in the NRD?
Answers:
Can I combine years of the NRD to analyze readmissions across years?
If your intention of combining multiple years of the NRD is to follow patients over time, this currently cannot be done. Each year of the NRD should be considered as a separate sample. The patient linkage numbers (NRD_VisitLink) do not track the same patient across years of the NRD. Additionally, the hospital identifiers (HOSP_NRD) do not track the sample hospital across years of the NRD.
If your intention is to analyze trends in readmissions over time, then multiple years of the NRD can used in combination.  For example, you can examine trends in readmission statistics for certain conditions or patient characteristics as long as you identify index and readmissions within a single data year.  Because the stratum identifier (NRD_STARTUM) and hospital identifier (HOSP_NRD) are reassigned each year, there is no issue related to the different clustering that occurs within each data year when multiple years of the NRD are combined. However, if you wish to report statistics for each individual data year, then you will need to stratify your results by data year (YEAR).
Does the NRD include data elements that directly identifies readmissions?
No, the NRD does not include any data element that directly identifies readmissions. The NRD was designed to support many different types of readmission analyses. Analysts can use the information contained in the NRD (e.g., data elements) to define the index event and readmission specific to their topic of interest:
  • Index event - the starting point for analyzing repeat hospital visits
  • Readmission - a subsequent inpatient admission within a specified time period; readmission may be for a specific cause or any cause.
For additional information on using the NRD for readmission analyses, refer to the Introduction to the NRD.
How are transfers handled in the NRD?
Readmission analyses do not usually allow the hospitalization at the receiving hospital to be counted as a readmission. To eliminate this possibility, HCUP collapses the pairs of records representing a transfer into a single “combined” record in the NRD and removes the original separate discharge records from the NRD. Transfer records are defined as having all of the following characteristics:
  • Discharge date of the first inpatient stay equaled the admission date of a subsequent inpatient stay.
  • The first record had a discharge disposition of transfer to an acute care hospital.
  • The second record was from a different hospital and had an admission source indicating a transfer.
We defined a discharge as a same-day stay if the discharge date for one inpatient stay was the same as the admission date of a second stay for the same patient (same as transfers), but there was no indication of a transfer by the discharge disposition or admission source. Same-day stays may or may not have involved different hospitals. Same-day stays may indicate that a patient was discharged too soon and then needed to be returned to the hospital on the same day. However, it was also possible that these were transfer records with an incorrect or missing discharge disposition and admission source.
We collapsed records that were part of transfers or same-day stays into a single combined record. These combined records account for about three percent of records in the NRD and are identified by the data element SAMEDAYEVENT. The value of SAMEDAYEVENT is defined as follows:
  • Transfer involving two discharges from different hospitals (value 1): Discharge date of one admission equaled the admission date on another record for the same patient. There was a discharge disposition of transfer to an acute care hospital on the first record and an admission source of transfer (in) on the subsequent record; two different hospitals were involved.
  • Same-day stay involving two discharges at different hospitals (value 2): The discharge date on the first inpatient stay equaled the admission date on a second inpatient stay for the same patient; two different hospitals were involved, but the coding of either the discharge disposition or admission source did not indicate a transfer.
  • Same-day stays involving two discharges at the same hospital (value 3): The discharge date on the first inpatient stay equaled the admission date on a second inpatient stay for the same patient; the hospital was the same on both records.
  • Same-day stay involving three or more discharges, same or different hospitals (value 4): Multiple records indicating a combination of transfers and other same-day events seem odd, but they do rarely occur in administrative data.
  • Not a transfer or other same-day stay (value 0). About 97 percent of the records in the NRD did not involve transfers or same-day stays.
Please note that if a patient had a discharge disposition of transfer and an admission source that also indicated a transfer, but the discharge date of the first stay did not equal the admission date of the second stay (e.g., the patient was admitted the next day because the transfer occurred at night), the two records are not considered a transfer in the NRD.
