[SO/URSA-PHARM] Patient Timelines of PDC Medication Supply

Object Description

Patient timeline with one record per period during which the patient is in a medication therapy episode for a PDC medication; the purpose of this object is to avoid double-counting supply when patients are on multiple families of medications within the same PDC category.

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)

• Date Fields

  • Period Start Date
  • Period End Date

• Module Fields

  • Is Oral Antidiabetic -- A child to the "Is Antidiabetic" medication type, indicates antidiabetic medications that can be taken orally as opposed other routes of administration (such as injections). Oral Antidiabetics are commonly separated from all antidiabetics for various adherence/quality measures (e.g., Stars PDC). (See also [URSA-PHARM] Antidiabetic)
  • Is Oral ACEI/ARB -- One of the Priority Adherence Medication types; indicates a medication classified as a angiotensin-converting enzyme inhibitor (ACEI) and an angiotensin receptor blocker (ARB) based on the Red Book Generic Cross Reference code and/or NDC being included in the CMS Stars measure specifications for Oral ACEI/ARB PDC measures. (See also [URSA-PHARM] Is Priority Adherence Medication, [URSA-PHARM] Active Priority Adherence Medication Type Category)
