From detailed guides to online courses – resources are available to provide you with the knowledge necessary to build and integrate EHR applications.

Information Model Overview

The following diagram introduces the high level subject areas contained in the conceptual information model. Subsequent sections in this chapter will review the model in more detail.

Figure 4: EHR Information Model

Information model definitions:

  • Health client: a health care client (a person who is eligible to receive, has received, or is receiving health care services in Ontario), or a client supporter (someone who is acting on behalf of or supporting someone receiving health care services in Ontario)
  • Health care provider: a person or organization providing health care or other health-related services or products
  • Client team: a group of client supporters and interdisciplinary health care providers working collaboratively with the health care client to support the health care plan. Each client team member is assigned responsibilities to facilitate care for the health care client appropriate to their role.
  • Health care plan: an integrated care plan, created by a health care client and/or provider(s), to manage the client’s optimal health, to address preventative measures, or to manage existing health conditions. A health care client may have one health care plan, or none. It contains client-centered activities, goals and targets based on best practice guidelines, and is monitored by client team members on a regular basis either directly or through automated and directed notifications. 
  • Client health profile: information about the health care client used to access his/her current health state and potential impacts on future health. It includes a diverse range of information, including, but not limited to:
    • Sensitivities, allergies, intolerances and adverse reactions to substances
    • Health conditions
    • Family history
    • Personal health characteristics
    • Special needs
    • Immunizations
    • Health directives
    • Health concerns
    • Barriers
    • Information consent
    • Emergency contacts
  • Health care encounter: an event where one or more services or products are provided to assess, maintain or improve a health care client’s health. The service or product may be from a health care provider, or may be self-provided. Any number of outputs may result from a single encounter. Outputs include information categorized by observations, diagnoses, dispense events, intake of substances, clinical procedures performed, requisitions, health care encounter locations, health care products and services provided. Several health care encounters can be linked into an episode of care.
