Building the After-Hours Triage Script for a Veterinary Clinic

"Is this an emergency or can it wait until morning?" The caller doesn't know — that's why they're calling at 11pm. Whoever answers needs a script that produces an answer without asking them to make a clinical judgment.

The professional backdrop

The AVMA Principles of Veterinary Medical Ethics state that when veterinarians can't be available, they should either stay reachable for follow-up or have arranged for emergency coverage and continuing care — and should give clients "readily accessible information to assist clients in obtaining emergency services." Your after-hours line is how a general-practice clinic meets that expectation. A voicemail that says "if this is an emergency, hang up and go to the ER vet" technically points somewhere, but it doesn't triage, and it sends every routine call to an emergency hospital the client may not be able to afford.

Script structure

Open with identification. Client name, patient name and species, and whether this is an existing patient of the clinic. An existing patient means the agent can pull the record for the on-call vet; a new caller may need redirecting to an emergency hospital depending on your policy.

Get the presenting problem in the caller's words, then move into the matching branch.

A branch per common after-hours reason. Build one for each of: vomiting or diarrhea; not eating or lethargy; known or suspected toxin ingestion; trauma or hit-by-car; difficulty breathing; unproductive retching with a distended abdomen (large-breed dogs); straining to urinate with little or no output (especially male cats); seizure; whelping or queening difficulty; eye injury; wound or active bleeding; post-operative concern.

Each branch is two or three questions, each answer mapped to a tier. The agent reads the questions in order and matches answers to your routing rule. If a branch needs more than three questions to reach a decision, it should route to the on-call vet — that's a clinical assessment, not a script.

Three tiers

• To an emergency hospital now. The agent gives your designated referral hospital's name, address, and phone, and — if your protocol says so — calls ahead.
• On-call veterinarian contacted now. The agent reaches your on-call DVM by your escalation ladder and connects or arranges a callback within a stated window.
• Advice plus a next-business-day appointment. The agent gives pre-approved guidance for the branch, books the morning slot, and logs it.

The middle tier is what keeps the script usable — it's where "vomited twice, otherwise bright and eating" goes, without either an ER referral or a 2am call to your vet.

Flagged combinations

Pre-define the symptom combinations that always escalate regardless of how the branch scores — for example, unproductive retching plus a visibly distended abdomen, or vomiting plus lethargy plus a known toxin. These are your call, written in advance, so the agent never has to assemble them on the phone.

Toxin calls get a standing resource

For suspected poisoning, the agent captures the product, the amount, the time, and the animal's weight, then routes per your rule — and has your standing resources in front of them: the ASPCA Animal Poison Control Center (888-426-4435, staffed 24/7; a consultation fee may apply) and the Pet Poison Helpline, whichever your clinic prefers, plus your on-call vet or referral hospital. The agent offers the resource per your instruction; they don't advise on decontamination.

The escalation ladder

Name the on-call DVM contact order, the wait window between attempts, and the fallback if no one answers — usually: refer the client to the designated emergency hospital and keep trying to reach the on-call vet, documenting every attempt with a timestamp.

Documentation

Every after-hours call: time, client and patient, presenting problem, branch, tier assigned, advice given, and outcome — in a format your team reviews first thing in the morning, so nothing that was handled overnight is a surprise.

The weekly review

Pull a sample of the week's after-hours logs and check them against the script: were the tiers right, did a client get sent to the ER for something the middle tier covered, did anything get an appointment that should have been seen that night. Mis-tiered calls tell you which questions need rewording.

The takeaway

A good after-hours veterinary line isn't a person deciding what's an emergency — it's a person running your branches and matching answers to your rules. Build the branches, define the flagged combinations, name the escalation ladder, and review the logs weekly.
