Published Fields

  • Data Model Keys

    • 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)
    • Primary Payor ID -- The internal database identifier (used, e.g., for joins and primary keys) for the Primary Payor. (See also [URSA-CORE] Primary Payor)
    • Primary Plan ID -- The identifier for the health insurance plan product that is the first party responsible for payment.
    • Primary Plan Attributee Provider ID
    • Empirical Attributee Primary Care Individual Provider ID
    • Empirical Attributee Primary Care Provider Group Provider ID

  • Patient Fields

    • Is Hospice in Last 12 Months -- Evidence of CMS hospice status or evidence of hospice services in the last 12 months. Typically used as a denominator exclusion.
    • Patient Age Integer -- Patient age, expressed as an integer, as of a reference date or interval.
    • Patient Age Category Tier 1 -- Non-overlapping ranges of the patient age in years into three categories; [01] Pediatrics < 19, [02] Adults 19 - 64, and [03] Older Adults >= 65. Coarser grain to the Patient Age Category Tier 2. (See also [URSA-CORE] Patient Age Category Tier 2)
    • Patient Age Category Tier 2 -- Non-overlapping ranges of the patient age in years representing finer grain categories than the Patient Age Category Tier 1. This field incorporates findings from publications on defining meaningful age groups in the context of disease. These ranges closely, but not exactly, align with standard age ranges such as those defined by the Medical Subject Headings (MeSH). See results of K-Means simple clustering method at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3825015/ (See also [URSA-CORE] Patient Age Category Tier 1)

    • Specialty Care Engagement Category
    • Primary or Specialty Care Engagement Category

  • Date Fields

    • 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)

    • 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)
