1.2 Telephone Triage, Urgent Symptoms & Emergency Scheduling

Telephone Triage, Urgent Symptoms & Emergency Scheduling

Telephone triage converts an incomplete patient report into information that a licensed clinician or approved protocol can act on. It is not a substitute for examination. A caller may use words such as blur, cloud, curtain, spots, flashes, pain, pressure, or distortion differently, so the technician should clarify rather than translate those words into a diagnosis.

A consistent opening sequence

First verify the patient's identity, a safe call-back number, location, and whether the patient is alone. Ask which eye is affected, when the change began, whether onset was sudden or gradual, and whether symptoms are stable, improving, or worsening. Record the patient's own description before adding structured details.

Useful follow-up questions include:

• Is vision reduced, distorted, missing in one area, or completely absent?
• Are there new flashes, a sudden increase in floaters, a shadow, veil, or curtain?
• Is there pain, photophobia, discharge, marked redness, nausea, headache, weakness, speech difficulty, or other neurologic symptom?
• Was there trauma, chemical exposure, recent injection, laser, surgery, or a current intraocular gas bubble?
• What was the most recent procedure, medication, eye, and date?
• Can the patient compare one eye with the other without driving or creating another hazard?

Do not ask the patient to press on the eye, remove an embedded object, instill an unapproved medication, eat or fast for a possible procedure, or drive with acute visual loss unless the authorized clinician or written protocol gives that instruction.

Red-flag patterns

Certain reports require immediate escalation because delay may threaten vision or general health. Examples include sudden profound monocular vision loss; a new curtain or field defect; flashes with a shower of floaters; severe or progressive pain, redness, photophobia, or vision reduction after an injection or surgery; penetrating or high-velocity trauma; chemical exposure; and ocular symptoms accompanied by stroke or giant-cell-arteritis warning signs.

These are patterns for routing, not diagnoses. Preserved central reading vision does not prove that a detachment is macula-on, and poor central vision does not establish how long the macula has been involved. Likewise, pain after an injection can have several causes, and infectious endophthalmitis can occasionally be painless. The correct response is rapid clinician review, not a treatment prediction over the telephone.

Sudden painless vision loss suspicious for retinal arterial ischemia is an emergency. Activate the clinic's emergency and stroke-routing plan without delaying for office-based pressure-lowering maneuvers. In an older adult, ask about new headache, scalp tenderness, jaw claudication, polymyalgia symptoms, fever, or weight loss and relay those answers immediately because arteritic disease changes the emergency evaluation.

For chemical exposure, advise immediate irrigation according to the emergency protocol while emergency help is arranged; history-taking must not delay flushing. For penetrating injury, protect the eye from pressure, avoid manipulation, and activate emergency care.

Recent-procedure calls

Ask for the procedure, treated eye, date, medication if known, and the discharge instructions already provided. Mild surface irritation can occur after antisepsis, but increasing pain, marked redness, photophobia, discharge, lid swelling, or declining vision needs prompt review. Do not reassure a caller solely because symptoms began early or late, and do not tell the patient that a vitreous tap, antibiotic injection, paracentesis, or other intervention will occur; the examining clinician makes that decision.

Disposition and closed-loop communication

Use the current physician-approved triage pathway. The pathway may direct emergency services, an emergency department or stroke center, immediate clinician contact, same-day examination, or another interval based on findings and local capability. If the patient cannot travel, lacks transportation, is outside the region, or refuses the recommendation, notify the clinician and document the barrier and revised plan.

Repeat the instructions in plain language and ask the caller to teach them back. Provide the exact destination and whom to contact if symptoms worsen during transit. Never promise that a particular timing guarantees visual recovery.

Documentation checklist

Record:

1. identity, caller relationship, call-back number, location, and time;
2. affected eye, onset, progression, exact symptoms, and associated systemic findings;
3. recent procedures, medications, trauma, and relevant ocular history;
4. the protocol or clinician contacted and notification time;
5. instructions given, patient read-back, destination, and transport advice;
6. refusal, inability to comply, disconnected calls, and follow-up attempts.

Objective, contemporaneous documentation supports continuity and safety. Avoid labels such as definite detachment or definite infection unless documenting the licensed clinician's assessment.
