Mission & Charter

The Patient Administration Work Group supports the HL7 mission by defining the requirements and specifications to support the interoperability among clinical and non-clinical systems regarding patient encounters and administrative registries.

This group produces normative standards by:

  • Identifying requirements and providing specifications for exchanging:
    1. Demographic and administrative data used to describe patients, persons, service delivery locations and patient encounters [scheduled and/or actual], including healthcare providers, places, organizations, and their relationships in the context of healthcare encounters.
    2. Administrative data to describe resources, their availability, [for example, represented by schedules or by status], and regulatory topics such as licensing and credentialing information about individuals, animals, organizations and devices directly or indirectly involved in the delivery of healthcare services.
  • Identifying requirements and providing specifications regarding the dynamic behaviors involved in requests and their fulfillment with respect to:
    1. Additions and modifications to registries such as patients, persons, service delivery locations, healthcare providers, places, and organizations
    2. Scheduling of appointments for services, encounters and associated resources. These processes include the functions of requesting, booking, notification, and modification pertaining to appointments and resources.
    3. Queries for information
  • Defining the domain and process of scheduling. As a domain, Scheduling offers a generic set of messages and behavior to implement any number of Scheduling scenarios. As a process, Scheduling offers an abstract data model and a set of operations to any domain within HL7 that utilizes scheduling concepts.
