Question 1

Where should I go for minor illnesses in Hong Kong?

Accepted Answer

Public A&E departments prioritise critical and emergency cases. Semi-urgent and non-urgent patients may wait longer. If your condition is minor, consider private clinics or primary care services instead of A&E.

Question 2

How does the A&E triage system work in Hong Kong?

Accepted Answer

Hospital Authority A&E departments triage patients into five categories (I–V) by clinical urgency. Category I (critical) and II (emergency) are seen first; Category IV (semi-urgent) and V (non-urgent) typically wait longest.

Question 3

What do the wait times mean?

Accepted Answer

The main wait-time table shows the 95th percentile wait for semi-urgent (Category IV) and non-urgent (Category V) patients, based on the past few hours. This means most patients in those categories waited less than the time shown. It is a reference only, not a guarantee.

Question 4

How do sudden emergencies affect A&E wait times?

Accepted Answer

When a hospital receives sudden severe cases — such as major accidents or heart attacks — staff and resources are directed to those patients first. Waits for semi-urgent and non-urgent patients can increase quickly, and the spike may not show up in historical wait figures right away.

Question 5

Where does the trend data come from?

Accepted Answer

Trend charts use historical waiting time records from the Hospital Authority open data programme, dating back to 2018. We analyse this dataset to show average waits by day and hour across Hong Kong public A&E departments.

Question 6

What is the best time of day to visit an A&E department?

Accepted Answer

Based on historical trends across all hospitals, 12 PM to 1 PM often shows the lowest waits. Early mornings and late nights tend to be busiest. Check live waits on our site before you travel.

Question 7

How often is waiting time data updated?

Accepted Answer

Our site refreshes wait time data approximately every 15 minutes from official Hospital Authority sources.

Question 8

Why does ae.wait.hk focus on semi-urgent and non-urgent categories?

Accepted Answer

Patients in Category IV and V often have time to compare hospitals before travelling. Those in critical, emergency, or urgent categories should seek care immediately rather than comparing waits. Higher Cat IV/V waits often correlate with busier departments overall.

Question 9

What do critical and emergency management status icons mean?

Accepted Answer

On the wait-time table, icons next to a hospital name show when the Hospital Authority reports the department is managing critical or emergency cases. These often appear during busy periods and can mean longer waits for semi-urgent and non-urgent patients:

Question 10

How can I see trend data for a hospital?

Accepted Answer

On the home page, click a hospital row to open a panel with live busyness, hourly trends, and contact details. To see the full trend chart and wait times by triage category, go to All Hospitals and select a hospital.

Question 11

How can I determine my triage category before visiting A&E?

Accepted Answer

You cannot know your triage category before arrival. The Hospital Authority does not disclose this in advance. An experienced nurse assesses you after registration and assigns Category I–V based on clinical need.

Question 12

I have more questions about the Hospital Authority — where should I look?

Accepted Answer

This site is not affiliated with or endorsed by the Hospital Authority.

Question 13

Accepted Answer

From 1 January 2026, eligible persons (valid HKID) pay HK$400 per public hospital A&E visit. Patients triaged as Category I (critical) or II (emergency) are fee-exempt. Non-eligible persons pay HK$2,100 with no exemptions. Fees are set by the Hospital Authority.

Question 14

How are wait times predicted?

Accepted Answer

Trend charts show estimated waits for the next 1, 2, and 3 hours. These forecasts use a machine learning model trained on recent Hospital Authority historical data.
