Over 28 million elective surgeries across the globe could be cancelled as a result of the Covid-19 pandemic – leading to patients facing a lengthy wait for their health issues to be resolved, a new study reveals.

The CovidSurg Collaborative has projected that, based on a 12-week period of peak disruption to hospital services due to Covid-19, 28.4 million elective surgeries worldwide will cancelled or postponed in 2020.

The modelling study, published in the British Journal of Surgery, indicates that each additional week of disruption to hospital services will be associated with a further 2.4 million cancellations.

Led by researchers at the University of Birmingham in the United Kingdom, researchers collected detailed information from surgeons across 359 hospitals and 71 countries on plans for cancellation of elective surgery.

This data was then statistically modelled to estimate totals for cancelled surgery across 190 countries.

The researchers project that worldwide 72.3% of planned surgeries would be cancelled through the peak period of Covid-19 related disruption.

Most cancelled surgeries will be for non-cancer conditions.

Orthopaedic procedures will be cancelled most frequently, with 6.3 million orthopaedic surgeries cancelled worldwide over a 12-week period.

It is also projected that 2.3 million cancer surgeries globally will be cancelled or postponed.

In Malaysia, the cancellation rates for surgeries during the peak 12 weeks of Covid-19 disruption were estimated as follows:

  • Benign surgeries - 81.5% (134,725 cases)
  • Cancer surgeries - 41% (16,992 cases)
  • Obstetric surgeries - 26.1% (2,978 cases)
Overall, the total number of cancelled surgeries is estimated to be 154,695 (70.9%).

In the UK, the National Health Service (NHS) advised hospitals to cancel most elective surgeries for 12 weeks.

It is estimated that this will result in 516,000 cancelled surgeries, including 36,000 cancer procedures.

These cancellations will create a backlog that will need to be cleared after the Covid-19 disruption ends.

Meanwhile, the backlog of surgical cases, not including obstetric cases, in Malaysia is estimated to be 151,717 cases.

If, after the disruption ends, the UK NHS increases the number of surgeries performed each week by 20% compared to pre-pandemic activity, it will take 11 months (44 weeks) to clear the backlog.

It will take roughly the same amount of time (45 weeks) for Malaysia to do the same.

However, each additional week of disruption will lead to the cancellation of an extra 43,300 surgeries in the UK and nearly an extra 12,900 surgeries in Malaysia, significantly extending the period it will take to clear the backlog.

Birmingham's NIHR Global Health Research Unit on Global Surgery consultant surgeon and senior lecturer Mr Aneel Bhangu commented: "During the Covid-19 pandemic, elective surgeries have been cancelled to reduce the risk of patients being exposed to Covid-19 in hospital, and to support the wider hospital response, e.g. by converting operating theatres in to intensive care units.

"Although essential, cancellations place a heavy burden on patients and society.

"Patients' conditions may deteriorate, worsening their quality of life as they wait for rescheduled surgery.

"In some cases, e.g. cancer, delayed surgeries may lead to a number of unnecessary deaths.”

His colleague, research fellow Dr Dmitri Nepogodiev said: "Each additional week of disruption to hospital services results in an additional 43,300 surgeries being cancelled, so it is important that hospitals regularly assess the situation so that elective surgery can be resumed at the earliest opportunity.

"Clearing the backlog of elective surgeries created by Covid-19 will cost the (UK) NHS at least £2bil (RM11bil).

"The government must ensure that the NHS is provided with additional funding and resources to ramp up elective surgery to clear the backlog.”
