Friday 21:00–01:00 walkout rate is 16.1%. The rest of the week sits at 6.6%.
285 ER arrivals in the Friday late window; 46 walked out. At our
$220 per-triage estimate, that's $10.1K
of forgone revenue in the cluster alone, with $5.9K
directly recoverable if the cluster fell to the baseline walkout rate.
The seeded cause in our synthetic data is no-DVM-on-shift weeks (CVT-only Fri 21:00 coverage). The matching
operational fix is a DVM rotation onto the Friday late shift and a written locum-cover plan for the
remaining Fridays — a scheduling recommendation, measured only; nobody is contacted. Veterinary ER walkout
rates are not published as a public benchmark, so this 6–7% baseline is a Central Uplift estimate; Instinct's
State of ER & Specialty Veterinary Care 2024 found 16% of ER patients wait more
than two hours, consistent with walkouts being a real, material loss.

What this looks like in your stack today.
Heatmaps over (day-of-week × hour) aren't in BluWave's standard kit; Vetspire reports
weekly aggregates by site rather than hourly density. The same insight could be hand-built in Looker if you have
a data engineer who can stand up the dimensional grain — typical effort is 2–3 weeks once the warehouse is fed.

Cited context. The ER walkout baseline is a Central Uplift estimate — no public veterinary ER LWBS benchmark exists. Per-triage revenue ($180–$280; we use the $220 mid-band) is anchored to the AAHA Veterinary Fee Reference (11th ed.), ER triage exam codes. This is a measure-only operational view: the recommendation is a staffing change the operator makes, never owner outreach. Press Q for the query this page ran.
