How does HCUPnet work? A step-by-step description of the query process.

How does HCUPnet work?

HCUPnet is based on aggregate statistics tables to speed up data transfer and protect individual records, so not all possible queries can be addressed. If a query is not possible, HCUPnet will not allow you to choose certain parameters. If there is a query you'd like to see that HCUPnet does not support, please contact us at hcup@ahrq.hhs.gov.

With HCUPnet, you build your query step-by-step. Here are the basic steps:

Step 1: Select the focus of your query.
Click National Statistics if you want information on the entire U.S.
Click For Children Only if you want to focus on children.
Click State Statistics to see what State data are available.
Check out Quick National and State Statistics to see if the information you want is available here in ready-to-go, fully sortable tables.
Click AHRQ Quality Indicators to get information on the quality of the health care system in the U.S.

Step 2: Select the type of query you want.
By Diagnosis or Procedure gives you detailed statistics for particular diagnoses or procedures.

You'll be able to get statistics by ICD-9-CM codes, by CCS category (a clinical grouper that puts ICD-9-CM codes into clinically homogeneous categories), by DRG (diagnosis related groups that are used by many insurers for reimbursement purposes), or by MDC (general groups of DRGs that comprise body systems).
If you're interested in statistics about all patients in general, click All Stays.
Click Trends if you want to see tables and graphs with trends over time.
Click Rank Order if you'd like to rank diagnoses or procedures by such factors as number of discharges, charges, or mortality rate.

Step 3: Select the Outcomes and Measures. HCUPnet provides a wide range of measures:
Number of discharges
Length of stay
Total charges
Total costs
Aggregate charges
Percent died in the hospital
Discharge status
Percent admitted through the emergency department
Percent admitted from another hospital
Percent admitted from a long term care facility

Step 4: Select patient and hospital characteristics. With HCUPnet you can Compare Patients by:
Age
Gender
Primary payer
Median income of the patient's ZIP code

And you can Compare Hospital Types by:
Region of the country
Teaching status
Location
Bedsize
Ownership/control

Step 5: Results. You then get your results in a format that can be printed or downloaded or you can instantly rerun the same query on another database within HCUPnet.

A navigation bar above the query pages lets you know where you are in the HCUPnet system. You can use the navigation bar to go back to previous pages.
