A global study has revealed that establishing 鈥楥OVID-19-free鈥� areas in hospitals for surgical patients could save lives during additional waves of the pandemic, reducing the risk of death from lung infections associated with coronavirus.

Researchers working collaboratively around the world found that hospitals can continue safe surgery by setting up COVID-19-free areas to minimise the risk from the coronavirus. Areas were set up in small independent hospitals and large hospitals with emergency departments, with strict policies ensuring that no patients treated for COVID-19 were mixed with surgical patients.

In Australia, it is estimated that around 55,000 operations take place each year for the five most common surgically treated cancers: breast, prostate, colorectal, lung and melanoma. Setting up COVID-19-free hospital areas could protect patients from coronavirus risk and allow safer surgery to continue, even if the virus infection rises again in one or more of our major cities.

Led by researchers at the , the comprises experts from over 130 countries. The group has published its findings in the . Data from Australia was collected by more than 100 trainees and Fellows from the .

The study examined data from 9171 patients in 55 countries, across five different continents from the start of the pandemic up to the middle of April 2020.

Pulmonary (lung) complication (2.2% vs 4.9%) and rates of death after surgery (0.7% vs 1.7%) were lower for patients who had their hospital treatment in a COVID-19-free area. However, only 27% of patients received care in these protected areas.

Collaborative lead in Australia, Consultant Surgeon and Royal Australasian College of Surgeons Fellows, Dr Peter Pockney, from the University of Newcastle, said, 鈥淎s health providers provide elective cancer surgery, they must look to protect cancer surgery patients from harm by investing in dedicated COVID-19-free hospital areas. These can be tailored to the resources available locally, ensuring that patients treated for COVID-19 are not mixed with patients needing surgery.

鈥淗owever, this represents a significant challenge to the hospital system around the country. Governments and hospital providers must help to fund this major redesign of surgical services if and when the virus affects us again and provide protection for patients.

鈥淐OVID-19-free areas could save many lives during future waves, by allowing surgery to continue safely despite high rates of infection in the community.鈥�

The study was funded by a (NIHR) Global Health Research Unit Grant. It covered adult patients undergoing elective surgery with curative intent for a range of suspected cancers including bowel, gullet, stomach, head and neck, lung, liver, pancreas, bladder, prostate, kidney, womb, cervix, ovarian, breast, sarcoma and brain tumours.

Dr Nagendra Dudi-Venkata 鈥� a surgical trainee and study leader in South Australia 鈥� commented, 鈥淢ajor reorganisation of hospital services to provide COVID-19-free areas for elective surgery must be justified by evidence like this, as it redirects time and resources away from other services. We have proved that those efforts are essential in protecting patients undergoing surgery during the pandemic.

鈥淥ur data showed that COVID-19-free hospital areas were beneficial when the rate of infection in the community was both low and high. We recommend that COVID-19-free areas are set-up in all countries currently affected by the pandemic, including those likely to suffer from future waves.

鈥淗owever, overcoming the challenges of setting up such pathways, including separate hospitals to provide elective surgery, may lead to unintended consequences. Consequences for hospitals must be carefully monitored to achieve the best balance of health care for patients.鈥�
