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.

Focus:

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.

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.
