After the ER: the first 24 hours at home

ER discharges happen fast, and the instructions are usually thin. Sometime around midnight a nurse hands you a two-page printout, the door slides open, and you are walking your parent to the car. The next twenty-four hours are when the small things become big — a missed dose, a confusing instruction, a pain that was managed in the ER but is not now.

This guide is the first-twenty-four-hours plan for the family bringing a parent home from the emergency department: what to ask before you leave, what to set up tonight, who to call, and how to write down what you saw so the next provider can use it. Plain language. Built from the questions families ask after the discharge papers stop making sense.

Before you leave the ER: three minutes of questions

ER discharge papers are usually generic and the nurse handing them over is one task into the next. The three minutes between the printout and the parking lot are when you ask the questions that the paper does not answer. There are three.

First: what is the working diagnosis? ER diagnoses are often described as 'most likely' rather than confirmed — the imaging or the labs may still be pending. Ask whether anything is still being followed up. Second: what changed about the medication list? Did the ER start anything new, stop something, or change a dose? Get the change in writing. Third: what warning signs mean call back, and what means come back? Get both lists, specific to the working diagnosis, before the door closes.

For the longer printable version of the questions to ask before any hospital discharge, see What to ask the hospital case manager. ER discharges are shorter conversations but follow the same pattern.

The 'command station' on the main floor

Inside the first hour at home, set up a single spot on the main floor where everything for the next twenty-four hours lives: the ER printout, the printed medication list (if there is one), a glass of water, the after-hours nurse-line number on a sticky note, a phone within reach, and a small notebook or notes app to write down anything you notice. One spot for everything.

If your parent will be sleeping on a different floor than usual, the command station goes wherever they will actually be — the couch, a daybed in the living room, a guest bedroom. The point is that everything anyone might need at 3 a.m. is within one arm's reach of where they are. The middle of the night is not when you want to be hunting for a sticky note.

Three check-ins, on a clock

Pick one person to be the discharge-day point of contact for the first twenty-four hours. Not the whole family — one person. That person does three check-ins, on a clock.

• Four hours: are we home and settled?A call or text to the family at four hours after discharge: home, eating something light, water beside the chair, first dose if appropriate.
• Eight hours: how is the first night going?Pain level, mobility to the bathroom, any new symptom, any confusion. Write the answers in the notebook so the trend is visible the next morning.
• Twenty-four hours: how was the night?Sleep quality, pain on waking, appetite at breakfast, any swelling, any change in alertness. Compare against the warning-signs page.
• Save two numbers in the phoneThe after-hours nurse line and the follow-up provider. Both saved before the first night, not during it.
• Print the medication list (or photograph it)One copy taped inside the kitchen cabinet, one photo in the phone of every adult in the home. Two backups beat one.
• Tape the warning-signs page to the fridgeThe page from the ER printout that names red flags — confusion, fever, swelling, sudden pain, trouble breathing — taped where every adult and any visiting helper will see it.

Medications: what the ER probably did not reconcile

ER discharges almost never include a real medication reconciliation. The ER team may have added one new medication (for pain, for an infection, for a specific symptom) without reviewing the rest of the home medication list. At home, gather every bottle on the kitchen counter and lay the ER printout next to them.

Three things to look for: a duplicate (the ER started a new blood-pressure medication but the home version is still in the pill organizer), an interaction (the ER started a new antibiotic that does not play well with a chronic medication), and a gap (a familiar pill that was skipped during the ER stay and has not been restarted). When in doubt, call the after-hours nurse line or the pharmacist tomorrow.

The companion post What is medication reconciliation — and why your parent’s list is wrong walks through this exercise in more detail.

What to write down (even when it does not feel urgent)

Write down anything that feels off in the first twenty-four hours, even if it does not feel urgent. Vague observations turn into useful sentences when you write them as you notice them. 'A little more confused than usual after dinner' is far more useful, three days later, than 'she has not seemed quite right.'

Date the entries. Time them. Note what your parent was doing when the change happened (waking up, after a dose, after walking to the bathroom). The notebook is what the primary-care provider will read on Tuesday morning to decide whether to bring your parent in or wait another day.

When to call the nurse line (and when 911)

The triage tree is the same one experienced caregivers use without thinking, and the same one new caregivers usually learn the hard way. Call 911 for chest pain or pressure, sudden one-sided weakness or slurred speech, severe shortness of breath, a fall with a head strike or possible broken bone, severe bleeding, a sudden change in consciousness, or any warning sign the ER printout specifically names as 'call 911.'

Call the after-hours nurse line for everything else that feels wrong but is not in the 911 list. A new pain, a low-grade fever, mild confusion, a missed dose, a question about whether to take or hold a medication, a wound that looks different. Nurse lines exist for exactly this conversation. Use them without apology.
