Floodwaters have engulfed large parts of New South Wales, with at least one person dead and almost 50,000 evacuated after days of heavy rainfall in a “one-in-500-year” flood event. The scale of the disaster is still unfolding and affected communities will be recovering for some time to come.
One question worth asking is: how ready are our hospitals to cope when disaster strikes?
A growing body of research, including our own, has looked at how hospitals might contend with disasters like floods, bushfires, heatwaves, cyclones or even mass injury events such as a stadium collapse. The answer? There’s room for improvement.
Australia is already prone to natural disasters, which are expected to become more frequent and severe as the climate changes.
Research around the world shows hospital administrators can better plan for how they’d cope if a disaster or terrorist attack wiped out their hospital’s capacity to function normally.
When flood strikes, large parts of the hospital stop working
In March 2022, rapidly rising floodwaters on Australia’s east coast posed an imminent threat to Ballina Hospital, on the NSW far north coast.
With a few hours’ notice, staff safely evacuated the whole hospital to a nearby high school. This included 55 patients, essential equipment, supplies and medications.
Our study documented this remarkable achievement via seven interviews with doctors and nurses integral to the evacuation.
Several key themes emerged:
- communication was disrupted: there was no mobile phone reception. Field hospital staff requested a satellite phone, but it was sent without any battery charge or a charging device
- staff shortages: flooded roads prevented doctors and nurses from reaching the hospital. However, they could get to the high school field hospital, which still had road access
- managing volunteers was tricky: community support was praised. However, there were so many volunteers, security was called to ensure volunteers didn’t get into spaces that would compromise the patient confidentiality, privacy and safety
- patient tracking was a challenge: it was hard to keep track of vulnerable evacuated patients with cognitive decline or behavioural impairment
- transport had to be improvised: cars, buses and taxis were used to transport equipment, medication and supplies
- triage for patient transfers and discharging was crucial: health professionals prioritised less critical patients first, as they often make up the majority. By swiftly addressing their needs, staff could then concentrate on the smaller group of patients requiring intensive care.
Some workers, dealing with their own personal losses during the evacuation, had to be sent home. One staff member told us:
There were a couple of nursing staff who also lived within the flood risk area, and they had children at home, so we needed to let them go home.
Another said:
We did end up with almost too many people wanting to help, which is lovely, but it becomes a problem because we don’t need this many people.
A third staff member said:
Everybody was accounted for. We had a list of patients at one end and then when they got there, they put a new list of who was there and who was coming; that was all written on a big whiteboard.
Disaster simulation: when a semi-trailer crash causes a stadium collapse
Natural disasters aren’t the only kind of catastrophe for which hospitals must prepare.
Our research has also looked at how hospitals might contend with a human-made disaster such as a mass casualty or injury event.
Our team studied a mass casualty simulation exercise at one of Australia’s largest public hospitals.
More than 200 hospital staff participated in the three‐hour long exercise, which simulated a semi‐trailer crashing into a stadium grandstand. Some 120 “patients” were taken to the hospital with crush, burn, smoke inhalation and other injuries.
In the simulation, clinicians had to adapt quickly. New patients were continuously coming via the ambulance ramp and private cars.
Participants had to make rapid collective decisions on treatment and transfers based on patient conditions and severity.
During the exercise, additional random disruptive scenarios were introduced to test the clinicians’ ongoing responses. This included the city mayor repeatedly calling the Hospital Emergency Operations Centre for updates.
Some key challenges included:
- some of the hypothetical patients died from a lack of critical care equipment
- an overwhelming number of minor injuries had to be managed
- clinicians were uncertain about how many casualties were en route to the hospital and how many beds to make available for them
- a shortage of orderlies to accompany transfers from the emergency department to surgical theatres or for scans
- difficulties in keeping track of patients and bed allocations.
We also observed hospital staff adapting to the situation. This included:
- paediatricians treating adult patients with minor injuries
- staff fast‐tracking triage
- staff manually ventilating patients using a specialised resuscitation balloon when mechanical ventilation equipment was unavailable
- running scans and imaging in batches instead of individually, due to the limited number of orderlies.
A growing body of research
Research shows that despite many hospitals having excellent, longstanding hospital disaster management plans, things can still go wrong. After the Fukushima nuclear accident in Japan, nearly half of evacuated stroke and renal failure patients died in vehicles or on arrival to another hospital.
Learning from hospital responses to disasters can help hospitals prepare for the future.
Overall, our research shows many Australian hospitals have excellent disaster preparedness planning. However, some areas require improvement well before disaster strikes. Adapting on-the-fly as your hospital is inundated with floodwater or struck by another disaster means things have been left too late.
