When patients leave hospital emergency departments before finishing treatment, the consequences are often invisible. They go home to wait, to deteriorate, or sometimes to develop complications that could have been prevented. More than 79,000 patients left NSW emergency departments before completing treatment in the last quarter of 2025, an increase of nearly 11,000 from the same time in 2024, according to the Bureau of Health Information.
The clinical significance here is substantial. ED access block results in ED overcrowding which reduces available treatment spaces, leading to prolonged waiting times, longer ED length of stay, further overcrowding, increased morbidity and mortality, increased inpatient length of stay, and increased rates of failure to wait to be seen. The research is clear: when EDs become dangerously overcrowded, patients die at higher rates than when capacity is adequate.
What the data tells us is that NSW faces a cascading system failure. The average length of NSW hospital stay for non-acute episodes was 19.3 days, the highest of any comparable quarter. This is the bottleneck: patients occupy hospital beds long after they are medically ready for discharge. Ambulances arrive at EDs but cannot hand over patients to a bed. Waiting rooms fill. Eventually, people leave.
The contributing factors sit across the entire health system, not merely within emergency departments. Delays result from hospital overcrowding partly due to increasing ED presentations, and long-stay patients awaiting discharge further reduce hospital capacity and delay admissions. Limited aged care and disability support services, along with staff and resource shortages, may compound the issue. A patient occupying a hospital bed who could be cared for in the community keeps that bed occupied and prevents an ED patient from being admitted.
To understand what solutions might work requires distinguishing between two different problems. The first is demand: more people are presenting to emergency departments, including a higher proportion with serious conditions. The second is capacity: hospitals do not have enough beds relative to population need. Simply telling patients not to come to emergency departments, or asking staff to work faster, addresses neither.
Meaningful reform requires investment in three areas. First, more hospital beds: funding extra beds and staff in partnership between the Commonwealth and States and Territories so that hospitals have a chance of ending ambulance ramping, meeting community demand and improving treatment times. Second, faster discharge: systems to discharge patients who are medically ready, particularly older patients and people with disability. Third, alternatives to hospital: funding alternatives to out-of-hospital care so people whose needs can be better met in the community can be treated outside hospital, with programs working with GPs to address avoidable admissions and readmissions.
The data from NSW shows that tinkering at the edges does not work. The patient who leaves an emergency department before treatment may return sicker. Some will suffer preventable harm. This is not failure of individual clinicians; it is failure of system design. The question for NSW and federal governments is whether the cost of fixing the problem now is higher than the cost of accepting it as normal.
