Tips for visiting the ER in San Francisco
Call 911 instead if it's severe
Chest pain, trouble breathing, stroke signs, heavy bleeding, or a serious injury — call 911 rather than driving. Paramedics start treatment on the way and you are assessed on arrival instead of joining the queue.
Bring your insurance card, ID and a medication list
Bring your health insurance card, photo ID, and a written list of your medications, doses and allergies. Federal law (EMTALA) means an emergency department must screen and stabilize you whether or not you have insurance — never skip care over coverage.
Expect to be seen by severity, not arrival
Triage means the sickest patient goes first, so the posted wait is an estimate for an average patient. Tell the triage nurse immediately if your symptoms change or get worse while you are waiting — that can change your priority.
Check the wait before you leave, and compare other San Francisco options
Waits move by the hour. Refresh this page just before you set off, and compare against the other departments listed further down — a longer drive can still mean a shorter total time.
Call a nurse line first if you're unsure
Most health insurers and hospital systems run a free 24/7 nurse advice line — the number is usually on the back of your insurance card. A nurse can tell you whether an emergency visit is warranted, or whether urgent care, telehealth or waiting until morning is safe.
Bring someone, and something to do
Emergency departments run 24/7 and waits of several hours are common. Bring a phone charger, water, any regular medication you take, and if you can, someone who can speak for you and drive you home.

Frequently asked questions
- What is the current ER wait time at UCSF Medical Center – Mission Bay Campus?
- UCSF Medical Center – Mission Bay Campus does not publish a live emergency wait time. WaitUpdates.com shows an estimate of about 1h 5m to first assessment (typically 45 min – 1h 25m) instead, based on the typical waits recorded for UCSF Medical Center – Mission Bay Campus. Treat it as a rough guide — call the hospital for anything time-sensitive.
- How long does a full ER visit take at UCSF Medical Center – Mission Bay Campus?
- Longer than the wait to be seen. At UCSF Medical Center – Mission Bay Campus, if you are admitted, the time from arriving in the ER to getting a hospital bed is typically 3h 40m – 5h 40m, and if you are treated and sent home, the whole visit typically takes 4h 40m – 7h 20m. Tests, imaging and specialist consults all add time after the first assessment, so plan for a long stay even when the waiting room looks quiet.
- How many emergency departments are there in San Francisco?
- WaitUpdates.com tracks 17 hospital departments in San Francisco, 17 of which are emergency rooms. They are all listed on this page with their current waits, shortest first.
- Should I go to the emergency room with the shortest wait time?
- Not necessarily. US emergency departments triage by severity (most use the 5-level Emergency Severity Index), not arrival order, so a sicker patient arriving after you is seen first. A department showing a longer posted wait may still treat you sooner if your condition is urgent, and the posted figure is an estimate for average patients, not a promise. Use the shortest wait to choose between comparable options — never to decide whether to seek care at all.
- Where does WaitUpdates.com get UCSF Medical Center – Mission Bay Campus's wait times?
- UCSF Medical Center – Mission Bay Campus publishes no live figure, so the headline number is an estimate. Visitor reports on this page are shown separately and are never blended into the official number, because a handful of reports can be skewed easily.
- Is UCSF Medical Center – Mission Bay Campus open 24 hours?
- Hospital emergency departments in California, including UCSF Medical Center – Mission Bay Campus, are open 24 hours a day, every day of the year, including holidays. Urgent care and walk-in clinics keep shorter hours, so check before traveling to one of those instead.
- What should I do if the wait in San Francisco is long?
- This page lists the 6 nearest emergency departments outside San Francisco with their current waits and distance, so you can weigh a drive against a wait. You can also call the 24/7 nurse advice line on the back of your insurance card to speak with a registered nurse about where to go. For something non-urgent, an urgent care center, a telehealth visit or a pharmacist can often help with far less wait. If symptoms are severe or worsening, call 911 — long waits are never a reason to avoid emergency care.
