TELUS Collaborative Health Record (CHR) has a fully integrated Drug Interaction Checker which is provided and powered by the leading Canadian company, Vigilance Santé.

This embedded functionality automatically runs a query/analysis for drug-drug and drug-allergy interactions when you add any new medication from the prescription creation section of the patient chart.

Adding Medications with the Drug to Drug Interaction Checker:

You can add a new medication to a patient's chart from an encounter, active medications or prescriptions

📌 Note: Medications are most commonly prescribed by providers from the prescription section of an encounter.

The following page will open: Prescription / Medication Screen is split into three sections:

1. The Medication Prescribing Screen (LHS)

a. From the General Tab, enter the drug you want to prescribe in the Search bar.

b. Complete the corresponding fields for the dose, frequency, duration, etc.

Once you have added/selected a medication, the drug to drug interaction checker automatically runs, checking for any drug interactions between the patient's current medications, allergies and any new medications prescribed.

2. Drug Interaction Screen (Middle)

This Alerts section will flag all of the possible drug to drug/ drug to allergy interactions between the patients' current medications and allergies.

For further details of each alert/interaction and further information on each prescribed medication (i.e. specific drug dosing, side effects, contraindications, etc.),

a. Click Full Report - this will take you to the Vigilance Santé (VS) Portal. (for more details on the VS Portal click here).

3. Patient's Allergies and current Medications (RHS)

Here you will find a list of the patients previously recorded allergies and current medications. This has been set up so that you have access to all the necessary information in one convenient location when adding additional medications.

⚠️ Important:

  • When searching for medications, it is important to select a medication that is associated with a DIN (Drug Identification Number). Only prescribed medications that have an associated DIN number will be included in the Drug Interaction Checker Analysis.

  • When you want to add allergies to the Patient’s Profile you can do so through the Summary View. It is important that allergies added have associated DINs (otherwise they will not be included in the Drug Interaction Check).

📌 Note:

  • All alerts are arranged according to severity.

  • Medications and allergies that are NOT included in the drug interaction analysis are flagged on the right hand side, in red “Not included in analysis”.


Can the drug to drug interaction checker work with my Formulary medications?

Yes, it can work with formulary medications. As long as you provide a valid DIN# when creating a formulary medication, it should be able to be included in the analysis (assuming that it also exists within the Vigilance Santé database).

Can I customize Drug Interaction Alerts on a per user basis?

Yes, it is possible to customize how interaction alerts appear within InputHealth on a per user basis. It is also possible to set an account alert threshold, this can however only be set up by the account owner. Please see the following Help Article for more details on customizing alerts:
