Urgency-Based Waitlists: How Specialty Clinics in BC and Ontario Can Prioritize Referrals
Quick answer
An urgency-based waitlist sorts accepted referrals by clinical priority rather than arrival date, using levels your physicians define. Patients are booked from the top of the list for the right physician or procedure, cancellations are backfilled from the same list, and every placement can be reviewed.
Why do arrival-order waitlists fail?
Because Canadian patients already wait a long time. The Fraser Institute’s 2024 survey put the national median wait from GP referral to treatment at 30 weeks, with about 15 weeks between the GP referral and the specialist consultation. Ontario recorded the shortest provincial median at 23.6 weeks. When the queue is that long, booking in arrival order means an urgent patient referred today waits behind every routine patient referred last month.
What is an urgency-based waitlist?
Instead of one first-come, first-served queue, the clinic keeps a waitlist per physician, service or procedure, sorted by urgency. Most clinics use three or four levels, such as urgent, semi-urgent and routine, each with a target time to be seen. Some specialties already have published benchmarks to anchor these levels. In gastroenterology, for example, the Canadian Association of Gastroenterology’s consensus sets targets ranging from 2 weeks for suspected malignancy to 6 months for screening colonoscopy.
How is the wait measured in Ontario?
Ontario’s Wait Time Information System measures Wait 1 from when a referral is received to the first specialist consultation, and Wait 2 from the decision to treat to the procedure for surgical care. Wait 1 is exactly the part an urgency-based waitlist controls: the time between a referral landing in your inbox and the patient being seen.
How should urgency levels be defined?
Start with the referral reasons your clinic sees most often.
Have physicians assign each reason a default urgency level.
Define red-flag findings that always escalate to physician review.
Set a target time to be seen for each level, using published benchmarks where they exist.
Review the rules every few months as patterns change.
Who decides a patient’s urgency?
Physicians. Software and staff can apply the rules your physicians define and suggest a level, but flagged referrals should always be reviewed by a physician, who can change the level at any time.
How do you keep the waitlist moving?
Backfill cancellations from the same urgency-sorted list immediately.
Keep contact details current so patients can be reached when a slot opens.
Track time on list against your targets for each urgency level.
Record availability so short-notice offers go to patients who can accept them.
Keep patients informed about their status, which reduces repeat calls.
Update referring offices when patients are booked.
What should you measure?
Wait 1 by urgency level, against your targets
Percentage of patients seen within target, by level
Cancelled slots refilled within 24 hours
Patients on the list with outdated contact information
Key takeaways
Sort by urgency, not arrival date.
Physicians define the levels and review flagged referrals.
Keep separate lists per physician or procedure and track Wait 1 against targets.
Backfilling cancellations from the right list protects capacity.
Frequently asked questions
How many urgency levels should a clinic use?
Three or four is common. Enough to separate urgent from routine without making the rules hard to apply.
Can routine patients wait indefinitely?
No. Time-on-list targets for each level make sure routine patients are also booked in a predictable order.
How do we handle patients who cannot attend at short notice?
Record their availability so backfill offers go to patients who can accept them.
