Online access to COVID-19 lab test results for Health Care Providers

If you are an authorized Ontario health care provider with access to one of the provincial viewers (ClinicalConnect™, ConnectingOntario ClinicalViewer and eHealth Portal) or an electronic medical record system (with OLIS to EMR) or Hospital Information System (with OLIS integration), you can access novel coronavirus (COVID-19) lab test results stored in Ontario Laboratories Information System (OLIS) in near real-time.

Digital Health Drug Repository Specification –FHIR (Release 3)

A key element of the EHR, the digital health drug repository (DHDR) is an electronic repository of dispensed drug and pharmacy service information that will expand on what has been available to date in the drug profile viewer. The DHDR currently includes records relating to publicly funded drugs, monitored drugs and pharmacy services representing approximately 70 per cent of the total dispensed medications in Ontario. DHDR data will improve patient care by allowing authorized clinicians secure electronic access to a patient's drug information. It will provide more time for diagnosing, treating and communicating with patients and improve patient outcomes by decreasing the risk of adverse drug events.

The DHDR specification provides a data store environment and web services for retrieving dispensed drug history data. This means clinicians can access clinically relevant data securely and efficiently at the point of care through regional clinical viewers.


DHDR Point of Care System Access FHIR API – also known as DHDR Release 3 – built on the FHIR (Fast Healthcare Interoperability Resources ®) standard R4 base specification was designed for provider application use. DHDR Point of Care System Access FHIR API specifies profiles for the following FHIR resources:

  • Medication
  • MedicationDispense
  • MedicationRequest
  • Organization
  • Patient
  • Practitioner

This specification ensures all information technology systems that retrieve drug data from the DHDR can exchange and understand the content through standardized HL7 messages based on FHIR specification and terminologies.


FHIR is an evolving trial-for-use standard, so additional changes by HL7 are expected. We will continue to monitor developments and assess whether or not there are impacts, and publish updates as they emerge.
