The number of Covid-19 patients at Groote Schuur Hospital in Cape Town is doubling every five days, according to a doctor, one of several at the hospital that we spoke to. The hospital will not be able to cope unless something is done.
“I expect there will be an excess of patients needing care even if all existing beds are opened,” said the doctor, who did not want to be named.
The hospital is currently running seven wards with over 120 Covid-19 patients, and four intensive care units with 19 Covid-19 patients.
Three of these wards are for confirmed Covid-19 cases, others are for suspected cases - in other words people with respiratory illnesses. A doctor said that the proportion of these patients testing positive is increasing rapidly. “I would estimate around 60% at this point.”
These are not additional beds. They were created by shutting down other services. The Department of Medicine, which currently runs the Covid-19 services in the hospital, has added the 120 Covid-19 (or suspected Covid-19) beds to its existing beds (approximately 100). In other words, the department has doubled its workload. “Additional capacity to absorb the expected number of Covid-19 patients will need to be created by collapsing other services to allocate beds and redeploy staff from surgical and other disciplines,” a doctor told us.
A doctor said to us that the number of Covid-19 patients is doubling about every five days. He said a “surge of cases” was expected in the next few weeks and “a transparent and feasible plan” to develop more capacity in the health care system was urgent. “This requires beds, oxygen, and importantly, staff, plus a triage system that can identify patients requiring hospital versus lower levels of care. The public could volunteer and be trained to support lower care Covid-19 facilities.”
One doctor said nurses and doctors were working 12-hour shifts. Several doctors have tested positive, all with mild symptoms so far, and a larger number of other staff, including nurses and porters. Burnout is “starting to creep in” but there are a number of support services in place.
But some doctors and nurses are apparently not showing up for work or reluctant to work with Covid-19 patients. In a message to doctors, a senior hospital manager pleaded with them to make themselves available.
“My reason for writing to you tonight is to make a plea for your assistance and to request you to dig deep in asking yourselves why you became doctors in the first place. Each and every one of us now need to be truthful to our oath and to our profession.
“Some staff have volunteered to work in these wards; some have been told to work without any choice and then there are many who have not come to the fore as yet.”
We asked a hospital doctor if the number of non-Covid-19 patients has declined. The doctor said it’s difficult to estimate because for some patients with respiratory illnesses, which increase at this time of the year, it’s not known if they have Covid-19 until their tests come back, which can take days. “There are still between 15 to 20 direct non-Covid medical admissions a day, which is maybe slightly lower than the usual numbers,” the doctor said.
“We have seen data from the province showing that HIV and TB services have been affected with fewer antiretroviral treatment initiations and TB diagnoses in April compared to previous months. As primary care is diverted to dealing with Covid-19 there will be fewer referrals to hospitals for other conditions, although on the other hand, there may be a higher risk for underlying chronic conditions to deteriorate and more patients will require hospital care.”
While there are no approved drugs in South Africa to treat Covid-19 yet, one factor makes a difference: getting oxygen to sick people.
One doctor explained: “The majority of patients will be either on no oxygen or low flow oxygen via nasal prongs or face mask. A subgroup of patients with respiratory failure require much higher concentrations of oxygen that can only be achieved by specialised high flow nasal cannula devices or mechanical ventilation. Because the outcomes with invasive mechanical ventilation (intubation) are so poor, we are supporting patients with non-invasive methods for as long as we can, and only intubate when these strategies fail. All patients admitted to intensive care will be intubated and mechanically ventilated. We have a very limited number of ‘high care’ beds and high flow oxygen devices, and this is rapidly becoming a limited resource in itself as we see many more patients with severe Covid.”
The hospital currently has enough oxygen for non-ventilated patients. But ultimately this too is a limited resource. Oxygen is supplied to the hospital via a liquid oxygen tank. And the limiting factor is its flow rate.
Meanwhile Mitchells Plain Hospital has reached its capacity. And News24 reported that Tygerberg Hospital’s intensive care unit is full. Groote Schuur is expected to start receiving many more patients from Mitchells Plain over the weekend, and a doctor told us that the hospital will struggle to cope.
