WA ED Wait Times -- Visualization Drafts
Recharts prototypes for Western Australia emergency department data. WA provides triage category 4 average wait times and a total-in-ED count, enabling richer analysis than raw wait counts alone.
A) List Route Enrichments
1. Hospital rows with sparkline + triage wait badge
Each row shows 24h patients-waiting trend, current count badge, and triage 4 average wait time. The vertical bar encodes the waiting-to-total ratio.
Armadale Hospital
71 in ED · 40 being treated
Fiona Stanley Hospital
113 in ED · 80 being treated
Joondalup Health Campus
116 in ED · 80 being treated
King Edward Memorial Hospital
11 in ED · 5 being treated
Peel Health Campus
40 in ED · 37 being treated
Perth Children's Hospital
37 in ED · 28 being treated
Rockingham General Hospital
49 in ED · 32 being treated
Royal Perth Hospital
79 in ED · 58 being treated
Sir Charles Gairdner Hospital
74 in ED · 52 being treated
St John of God Midland
80 in ED · 61 being treated
2. Aggregate WA-wide patients waiting
Total patients waiting across all 10 WA EDs over the last 24h. Dashed line is the period average (124).
3. Triage 4 average wait time ranking
Horizontal bars sorted by longest wait first. Category 4 (semi-urgent) should be seen within 60 minutes per Australasian Triage Scale. The 60-min reference line marks the target.
4. ED load composition -- waiting vs being treated
Stacked horizontal bars showing how many patients are waiting vs being treated. Sorted by total patients in ED.
B) Analysis / Detail Views
Charts below use Joondalup Health Campus as the focal hospital where applicable. Change with the dropdown above.
5. Crowding vs wait time bubble chart
X-axis: patients waiting. Y-axis: triage 4 avg wait (minutes). Bubble size: total patients in ED. Reveals whether crowding correlates with longer waits -- hospitals in the top-right quadrant are under the most pressure.
6. Triage 4 wait time comparison across hospitals
Overlaid triage 4 average wait for all WA EDs. Focal hospital (Joondalup) in solid lime, others in lighter tones. The 60-min ATS target is the dashed reference.
7. ED composition over time (Joondalup)
Stacked area showing the split between patients waiting and patients being treated over the last 24h. The total height is the total ED load.
8. Triage 4 wait vs patients waiting -- dual axis (Joondalup)
Composed chart overlaying triage 4 wait time (area, left axis) with patients waiting (line, right axis). Shows whether the two metrics move together or diverge.
9. Normalised radar comparison
Each hospital plotted on three axes (patients waiting, total in ED, triage 4 wait), normalised to 0-100 relative to the busiest hospital on each metric. Larger shapes mean higher load.

10. WA-wide average triage 4 wait trend
Average triage 4 wait time across all WA EDs over the last 24h. The 60-min ATS target is the green dashed line. Anything above the red dashed line (120 min) is double the target.
11. Waiting ratio over time (all hospitals)
Percentage of ED patients who are still waiting (not yet being treated). Higher ratios suggest bottlenecks in triage or bed allocation. Focal hospital highlighted.
