How to Issue a Prescription
Open the patient record → Drug menu → Add Prescription → select drug, dose, frequency, duration → review and Issue.
This is the standard prescribing workflow in CCMS — what every clinician does dozens of times a day. Use this guide for a routine acute prescription. For repeats, controlled drugs, allergy alerts, or error recovery, see the linked FAQs.
This page is a placeholder for the standard prescribing workflow. Steps below are an outline; full screenshots and worked examples will be added before launch. If you need a definitive answer right now, contact the CCMS helpdesk.
Before You Start
- Prescriber role (Doctor, MA with prescribing rights, or other authorized clinician)
- The correct patient record open and identity verified
- Smartcard logged in for the active session
- Knowledge of the patient's allergies and current medications (visible in the journal)
Step-by-Step Instructions
Open the patient record and verify identity
Always confirm the right patient before prescribing
- Use Quick Patient Search (
Ctrl + F) to open the patient. - Verify name, IC, and date of birth before any prescribing action.
- Check the allergy banner at the top of the record.
Navigate to the prescribing dialog
Open the Add Prescription window
- From the patient record, open the Drug menu.
- Select Add Prescription (or use the toolbar shortcut if configured).
Select the drug
Search by name, brand, or generic
- Type the drug name in the search field.
- Pick the correct entry from the dropdown — pay attention to strength and formulation.
- The system displays interaction and allergy alerts at this point — read them.
Set dose, frequency, and duration
The three fields that define every prescription
- Enter the dose (e.g., 500 mg).
- Choose the frequency (e.g., TDS).
- Set the duration or quantity (e.g., 5 days, or 30 tablets).
- Add instructions to patient (e.g., "Take after food").
Review and issue
Final check before the prescription is sent
- Review the full prescription summary on screen.
- Confirm dose, frequency, duration, and route.
- Click Issue (or Sign) to commit.
- The prescription is now part of the active medication list and visible in the audit trail.
Troubleshooting
Prescribing dialog will not open
Cause: Most commonly the multi-instance lock (only the first SystmOne window can prescribe).
Solution: See Prescribing First Instance Error for the full fix.
I issued the wrong drug or dose
Cause: A clinical error after issuance — wrong drug, wrong dose, or wrong patient.
Solution: See Prescription Error Handling for the recovery procedure, including PHIS coordination.
Allergy alert keeps firing for a drug I know is safe
Cause: The allergy entry on the record is over-broad (e.g., "all NSAIDs" when only one is implicated).
Solution:
- Review the original allergy entry with the patient.
- Refine the recorded allergy to the specific drug or class with documented clinical justification.
- Do not silently override — every override is logged.
