Digital Health Drug Repository (DHDR) Overview

Access to Drug Information through Your EMR!

Clinicians juggle many patient encounters and practice priorities every day in a limited amount of time. Simplifying this work and easing the burden on you is why OntarioMD (OMD) is focused on connecting your EMR to as many clinically valuable digital tools as possible—including Ontario Health's Digital Health Drug Repository (DHDR).

With seamless access from your EMR, the DHDR gives you as much information on drugs dispensed to your patients as is available. Knowing as much as possible about the drugs patients are taking helps you reduce the risk of adverse drug events such as medication errors, drug reactions, allergic reactions, and overdoses, and increases the likelihood of optimal patient outcomes.

The provincial DHDR is now available to all users of OMD-certified EMRs in good standing. OMD can begin the connection process with you today!

Benefits to Your Patients and Your Practice

  • Access patients' medications covered under the ODB program, drugs that are considered narcotics or controlled substances, as well as COVID-19 vaccination information, directly from your EMR.
  • If you use a provincial clinical viewer to access the DHDR, you will now have direct access from your EMR—you no longer need to log in to a separate portal to view the information, saving you time and effort!
  • Access to the DHDR from your EMR further enables:
    1. Improved patient safety, outcomes and continuity of care
    2. Decreased risk of medication errors and patient mortality
    3. A record of dispensed prescriptions and pharmacy services for more informed clinical decisions
    4. More time to diagnose, treat and communicate with patients
    5. More efficient medication reconciliation in case of medication recalls 
    6. Improved collaboration with other health care providers who also access the DHDR

Get ahead of the curve: 3 basics to get started

Your EMR vendor is making it a priority to give you access to the DHDR. Secure access to medication information through your EMR requires three prerequisites, and you may already have the first two:

  1. A ONE® ID from Ontario Health
  2. A PKI certificate, a digital certificate that proves your identity
  3. A client information form for Ontario Health

The sooner you start the process to access medication information, the sooner you can enhance patient safety! Contact us at today.

EMR Integration with the DHDR is mandatory

OMD is leading EMR integration with the DHDR in partnership with Ontario Health, the Ministry of Health, and vendors with OMD-certified EMRs.

In November 2021, EMR integration with the DHDR became mandatory. All vendors with OMD-certified EMRs must complete the work by November 2022 to maintain their OMD EMR certification.

Please contact your OMD Advisor or to express your interest in connecting DHDR to your EMR. Only OMD-certified EMRs can connect to drug information.
