Our Vizient data set includes a comprehensive set of tables to view line-item, patient-level, detailed data across a wide set of inpatient encounter-related information. Our data sets include de-identified, patient-level data for every member in the Vizient network, including most of UT-HIP members and affiliates.
As a database used primarily for Quality Improvement, this dataset provides patient-level risk-adjustment, based on Medicare Severity Diagnosis-Related Groups (MS-DRG), for the primary outcome measures: Mortality, Length of Stay (LOS), and Direct Cost. Through this, selected cohorts can be benchmarked against other custom-made groups.
The following de-identified tables, with some representative key fields, are available for consumption:
| Table Name | Table Description | Example Fields |
|---|---|---|
