Data Model Keys
- Encounter ID -- The internal database identifier (used, e.g., for joins and primary keys) for the encounter. (See also [URSA-CORE] Encounter)
- Patient ID -- The internal database identifier (used, e.g., for joins and primary keys) for the patient. This value is typically mastered, i.e., all records for the same patient, regardless of the source data system from which that record originated, should have the same Patient ID value. (Note that while the mastered Patient ID value might resemble a local identifier used in one of the upstream data sources, this does not indicate any special priority of that source system in determining the characteristics of the patient.) (See also [URSA-CORE] Patient)

Date Fields
- Encounter Start Date
- Segment Start Date -- The start date of the reporting segment. (See also [URSA-CORE] Reporting Segment)
- Segment End Date -- The end date of the reporting segment. (See also [URSA-CORE] Reporting Segment)

- Patient State Abbreviation
- Patient ZIP Code 5-Digit
- UW HIP Area Deprivation Index National Percentile -- A value between 1 and 100 representing the composite measure of socioeconomic deprivation from University of Wisconsin’s School of Medicine and Public Health. Scores are for Census Block Group geographic level, which generally contains between 600 and 3,000 people. Higher scores indicate more deprivation, so a score of 1 indicates the least deprivation while a score of 100 indicates the most deprivation. Percentiles are constructed by ranking the ADI from low to high for the nation and grouping the block groups into bins corresponding to each 1% range of the ADI. The 2019 ADI was constructed using the 2015-2019 5-year estimates from the US Census' American Community Survey and includes 17 component measures that span the domains of income, education, employment, and housing quality. It may be linked with the 9-digit ZIP code crosswalk, which was built to correspond directly to Census block groups. The 2019 ADI was released on 07/14/2021 and is the most recent version as of 02/02/22.
- UW HIP ADI Quintile Category -- The UW HIP Area Deprivation Index National Percentile grouped into 5 levels, each spanning 20 percentile points (ADI 1 is percentile scores from 1 to 20 while ADI 5 is scores from 81 to 100). Higher scores indicate more deprivation, so ADI 1 is the least deprived while ADI 5 is the most deprived. Quintiles are frequently used in health research. They give larger sample sizes per group and are easier to plot and interpret. Quintiles also carry less information and group more dissimilar patients. Quintiles are good for descriptive analyses while the original percentile measure is preferable for predictive modeling. (See also [URSA-CORE] UW HIP Area Deprivation Index National Percentile)
