Clinical Health Information Exchange (CHIE)

The Clinical Health Information Exchange (CHIE) is a clinical data repository that receives and stores patient information from multiple electronic medical record systems (eMRs). Patient information is aggregated and displayed in a single record so clinicians can quickly access their patient’s health history.

The Challenge

While clinicians could readily access patient information from the eMR system within their own local health district, they could not directly access this information from private hospitals or other local health districts. Lack of access to patient health information residing within different eMRs was preventing clinicians from providing continuity of care where patients had received care from multiple health settings or had transitioned between them.

The Plan

eHealth NSW developed a single clinical data repository to receive and store patient information from multiple different organisations regardless of their electronic medical system.

Known as the Clinical Health Information Exchange (CHIE), the repository allows clinicians to view eMR records for the same patient across different organisations. Only information from hospitals signed up to the CHIE is available to view via their local eMR.

Through CHIE, clinicians can view vital patient information including:

  • Demographics
  • Allergies and alerts
  • Problems and diagnoses
  • Past medical history
  • Encounters
  • Medications (on discharge)
  • Vital signs and observations (top 20)
  • Family history and social history and
  • A range of clinical documents such as discharge summaries, progress notes, operation reports and management plans.

This ensures patients receive better continuity of care no matter where they are treated, improving a patients healthcare experience.

The CHIE is an evolving and malleable platform that has allowed our clinicians to share and review the important, current documentation and data/results needed to care for patients in a variety of treatment scenarios. This includes helping us to provide seamless care between hospital and community encounters, as well as supporting tertiary care, both with and without transfers, between the various facilities in the LHDs/organisations contributing to the CHIE.

The Outcome

The Clinical Health Information Exchange was the first implementation of its kind in Australia.

eHealth NSW piloted the repository in September 2019 by connecting Northern Sydney and Central Coast Local Health Districts and the public/private hybrid Northern Beaches Hospital.

Since then, it has been rolled out to a further six local health districts and one hospital network and continues to be implemented across the state.

The Benefits

For clinicians, CHIE:

  • Supports patient clinical information visibility by providing access to data from other eMR domains
  • Facilitates continuity of care
  • Supports management of care for shared patients
  • Increases workflow efficiency
  • Helps inform clinical decision making and
  • Improves patient safety and service quality.
