I'm a GP. DH is a Consultant Anaesthetist working in ITU. Bit of an essay here, but I feel this is important.
I can only speak for my area, but we have 6 elderly care homes in our practice area, and over the past 4 weeks we have discussed what to do in the event of COVID-19 infection with EVERY patient of ours in those homes, or with the family if the patient does not have mental capacity for the discussion. We have written many emergency health care plans (EHCPs) and DNAR forms.
When the realities of what 'admission for treatment' means are properly discussed, we've had only one patient who wanted to opt for admission, and that only up to non-invasive ventilation. Most frail elderly people don't want to be separated from their regular carers and familiar environments, and many already had EHCPs in place. Remember that you only tend to end up in a care home if you couldn't manage independently with carers attending four times per day. Unless you have fairly advanced dementia, that generally means that physically you're very frail.
Very few dementia patients would be able to tolerate the nasal oxygen or CPAP, which is uncomfortable to wear, and requires you to sit/lie still. Sedating people seems to cause a rapid deterioration, which is why ventilation is a last resort, but this means they'd be potentially very frightened, in an unfamiliar environment, and unable to tolerate treatment, as they wouldn't understand what was happening.
As GPs, we are in daily phone contact with the care home staff by phone. We are taking turns in the COVID-19 home visiting service, which is staffed by district nurses, palliative care specialists, GPs and elderly care specialist nurses. We are providing palliative care medications/ syringe drivers if needed. If we run out of syringe drivers (which is a possibility), then we have figured out alternative medication regimens. We can alleviate pain, agitation, breathlessness, nausea, secretions etc, as we usually would for patients at the end of their lives. We are trying our best to provide some emotional support to the care home staff. All the care homes in our city have the same access to PPE as the GP surgeries.
The thing with COVID-19 is that if you're sick enough to need admission, you will almost certainly need critical care, whether for high flow nasal oxygen, CPAP or (if unavoidable) ventilation. Hospital doctors are reporting that the vast majority of patients that are sick enough to need admission are needing critical care, low flow oxygen doesn't make any difference. It isn't that we're admitting 'late' particularly, that just seems to be the nature of the illness: if you're going to deteriorate, it happens fast and hard.
Ventilated patients with COVID-19 need to stay under for a very long time (2 weeks on average). There are very few very elderly people that would be able to get off a ventilator after that long, whatever the reason for ventilation, as even well people become de-conditioned very rapidly during ventilation. It is thought that the prolonged duration of ventilation is one of the reasons why it has such a low success rate.
We are not 'leaving the elderly to die', we are trying to ensure a comfortable, dignified death for patients for whom the chances of survival even with maximum intervention are minimal, and would lead to a massively reduced quality of life even if they did survive. Patients who are old, but previously fit and well, are being admitted if they want to be. No-one is declining care on the basis of age alone.
Interestingly, some Italian doctors who work in the UK are saying that part of the reason Italy had such overwhelm of the health care system is because they don't practice the same 'ceiling of intervention' discussions that are part of normal care for the frail elderly in the UK. Therefore at the start of their epidemic, they intubated and ventilated a large number of frail elderly, before they knew how bad the peak was going to be. When they started seeing massive numbers of sick patients, they had already filled their critical care capacity with people whom they then couldn't extubate.
This is a brand new infection. We are learning as fast as we can, and trying to make decisions based on the best evidence we have available at the time. I completely agree that patients who are known to be COVID-19 positive should not be getting discharged to homes with no COVID-19 cases, and that we need to support carers who are simply not used to have to deal with palliative care for so many people simultaneously, but beyond that, we are doing the best we can in both primary and secondary care to ensure that people get the care that is best for them as individuals.
