Doctors’ haste to mechanically ventilate patients at the start of the pandemic might have contributed to the higher rate of death in spring compared to now, a senior medic has said.
Dr Alison Pittard, the dean of the Faculty of Intensive Care Medicine in London, said doctors’ evolving understanding of the virus had dramatically upped the survival rate.
At the start of the pandemic, just 66% of people in hospital with the virus survived, compared to 84% in August. Dr Pittard told Sky News:
We used to put patients straight onto mechanical ventilation – so we would bring them to intensive care, sedate them and put them on ventilators. But we have slowly started to realise that perhaps we could manage some patients without doing that.
She said intensive care teams now use a variety of interventions to help patients breathe, and full mechanical ventilation is a last resort.
Pittard said there’s no evidence to suggest Covid-19 has become less dangerous despite falling death rates in the UK. She said that, although treatment is improving, social distancing is also having an impact on transmission and viral load.
It is still a very deadly virus, although the majority of people who still become infected will have a very, very minor illness or may not even know that they are ill at all. For those people that require hospital admission, for those that come to intensive care it’s still a very severe disease.
If you end up in critical care with Covid pneumonia you are almost twice as likely to die than somebody who’s admitted with a pneumonia not due to Covid - so it is still something to be worried about.
Keeping critical care facilities open to non-Covid patients will be vital to minimising the collateral damage of the next wave of the pandemic, Pittard added.
She said that minimising transmission within the community was the best way to prevent urgent care units becoming overburdened. Pittard said the focus of the next wave of the pandemic “isn’t going to be on Covid patients getting access to healthcare, it is going to be for those patients that don’t have Covid”.
If we can keep community transmission down it means we can treat everybody who needs healthcare and that is the great desire for everyone working in the NHS at the moment.
