Emergency departments are clogged and patients are waiting for hours or giving up. What's going on?

Around 25,000 people^[1] visit hospital emergency departments across Australia every day. Many of them are reporting waiting for hours to be seen. Some give up^[2] and leave, only to have their condition deteriorate.

“Ambulance ramping” – where ambulances queue outside hospitals to hand over patients – has become more common and means some people wait long periods before they even arrive at emergency.

Of the 8.8 million^[3] presentations at emergency departments each year, one in three people wait more than four hours to be treated and admitted to a ward for further care, or to be discharged.

Our fragile public health system and its staff need urgent attention before emergency departments can recover.

Not a new problem

Demand for urgent hospital care is increasing Australia-wide, placing prolonged strain on the acute care services provided by emergency departments. But demand has been building over decades, not months.

According to the Australian Institute of Health and Welfare^[4], the number of people presenting at public emergency departments increased by 3.2% on average each year from 2014–2019, mostly due to an ageing population that is experiencing more complex health issues.

Perhaps surprisingly – and despite ups and downs in some cities over shorter periods – overall demand on emergency departments decreased^[5] during the peak COVID period as people chose to stay home or were in lockdown. Volumes have only recently recovered to normal levels.

Two key issues stand in the way of people getting emergency care.

First, the public health system is already at capacity, so even small increases in demand send it into gridlock.

Second, with more and more staff unable to work due to illness, including COVID infection, burnout and now influenza, there are not enough staff to look after patients.

No slack in the system

Emergency departments are in the business of preparing for the unexpected, whether it’s a surge in COVID infections or mass injuries from natural disasters, large-scale accidents or a terrorist attack.

The surge becomes magnified when the event also affects health-care staff or facilities, taking away care capacity as demand increases. We are currently facing an early influenza surge, with rates around what’s typically seen in late June^[7].

Systems can cope with unexpected events by allowing “slack” or holding excess capacity in normal times. Unfortunately, our health-care systems have been stripped of excess capacity. Cuts^[8] in the name of efficiency have been implemented by successive governments, without fully appreciating the implications on health-care supply in times of need.

Working harder comes at a cost

During COVID, extra capacity was created by ambulance and hospital staff working faster and longer. Longer term, this results in burnout.

Because burnout is harder to see than ramped ambulances, it’s less likely to make the evening news – but it’s a more critical and complex problem.

Around 20,000 Australian nurses^[10] left the profession in 2021, many citing stress and abuse^[11] suffered on the job.

Around 8% of paramedics^[12] suffer post-traumatic stress disorder, twice the average for Australian workers. Almost one third are diagnosed with depression.

Just add beds?

The addition of “more beds” sounds like a practical solution – but hospital beds rely on staff (particularly nurses) to take care of the patients in them.

Addressing hospital staff shortages is less straightforward. There is a long lead time to train additional nurses and we can’t rely solely on importing them from overseas. New Zealand is already concerned we’re going to take many of its nurses to help our aged care sector^[14] and other countries are competing for skilled hospital staff.

In an attempt to relieve pressure, governments want to divert those with less severe illnesses or injury away from emergency departments to urgent care centres or 24-hour GPs. This may improve access to care for some patients, but it may not substantially reduce emergency demand. New South Wales data^[15] shows surprisingly few people went to emergency when they could have gone to a GP.

Improving flow

The long-term solution to emergency department blockages is to increase throughput.

Imagine the hospital as a bathtub, and the patients as the water streaming into the bath. Increasing the bath size is a temporary fix. If you can’t turn off the tap, it will quickly fill. We need to work on the drainage system – increasing the size of the drain and unblocking any pipes that are clogged.

Hospitals have a duty of care to discharge patients to a safe environment. To quicken hospital discharges, we need more community capacity to house people with disability, people with mental health conditions who need supported care, older people who can no longer live alone without assistance, and homeless people.
